• 8:45Lex Fridman?

  You've described that the Byzantine Empire is the Roman Empire, that calling it the Byzantine Empire is an invention of historians writing long after the empire has collapsed, that the people of that time considered themselves Romans, and that the so-called Byzantine Empire never actually existed, that it was, in every legal and cultural sense, the Roman Empire, continuing unbroken. So, let's get our terms right in the grand historical context. What is the Byzantine Empire? And why should we just call it the Roman Empire?

• 9:21Speaker 01

  So Lex, the burden of proof is on those who would assert that what we've been calling the Byzantine Empire is something other than the Roman Empire, because all of our sources are very clear about this. And we've known about this, we've always known about it. It's almost a form of cognitive dissonance, right? It's like when you know something is the case, but you carry on as if it's not. So, the Eastern Roman Empire, this is the direct continuation of the Ancient Roman Empire in the East. Everybody knows the Western Empire fell in the 5th century. And for many conceptions of Western history, that was sufficient, like that's when we just called it, the Roman Empire fell in the 5th century. And we kind of, yeah, we kind of know that the eastern half survived, but we don't want to include that in our cultural genealogy.

• 10:04Speaker 01

  And so, we kind of pretend that it became something else. But in fact, it called itself the Roman Empire. Its subjects were Roman citizens. They called themselves Romans all the way down through to the end and beyond. So, there are a number of reasons why Western Europeans wanted to think that the Eastern Empire is something different. And those reasons have created these models where they called it Empire of the Greeks for 1,000 years, then they switched to Byzantine Empire for very political reasons. Now that's collapsing. So, we're now moving into a phase where we have the Long Roman Empire. We recognize that the history of the Roman state, the Roman polity... Is something that lasts an extraordinarily long time, very unique almost in history, from antiquity, like archaic period,

• 10:50Speaker 01

  down to the 15th century.

• 10:52Lex Fridman?

  I think it would be really nice to actually look just for a brief moment at the grand scale of the, uh, the full Roman state as it lasted for over 2,200 years.

• 11:04Speaker 01

  Yeah.

• 11:05Lex Fridman?

  So it's founding 753 B.C. To, let's say, the fall of Constantinople in 1453 A.D. So can we try to give a big picture overview of everything that happened?

• 11:18Speaker 01

  Okay, so first we have a period of the kings. This is almost legendary from like the 8th century B.C. Down to around 510 B.C. So this is when Rome is ruled by a series of local kings. The kings are expelled and the republic, or what we call the republic, is instituted, and this is a regime that's governed by mostly an aristocracy, but with cooperation from the people of Rome. In various ways, the arrangements change over the centuries. So that lasts for about five centuries. And then we have the end of the republic in the era of Julius Caesar and Augustus Caesar, when the civil wars lead to the creation of an imperial monarchy, right? Under Augustus.

• 12:00Speaker 01

  So that's, we date that roughly either 27 B.C., something like that. And thereafter, it is an imperial monarchy for the next millennium and a half. Very broadly, we can divide that into two phases. One where the center of power is in Rome and one where it's in Constantinople. And, you know, we can debate the dates of when that transition takes place. These big transitions usually take place over long periods of time. They're not like very sudden. So that's the big picture. Kings, republic, imperial monarchy.

• 12:35Lex Fridman?

  The Roman Kingdom, the Roman Republic, the Roman Empire.

• 12:39Speaker 01

  Yes.

• 12:39Lex Fridman?

  And then the West and East Roman Empire.

• 12:42Speaker 01

  Yes.

• 12:43Lex Fridman?

  And then maybe, what are the different terms that we could be using for the Byzantine Empire, including Byzantium?

• 12:52Lex Fridman?

  Is it also fair to say the late Roman Empire?

• 12:56Speaker 01

  So late Roman Empire, we use for both east and west. Starting around the reign of Diocletian, maybe even a bit earlier, so during the third century AD. And that goes down to maybe the early 7th century. So that period, we call late Roman Empire. And if you ask me to define its principal characteristics, it would probably be the tax system and the administration, the bureaucracy of the later Roman Empire. It's that that comes from mostly Diocletian and Constantine's reforms.

• 13:25Lex Fridman?

  And Diocletian was in the 3rd century.

• 13:28Speaker 01

  Yes, 284 to 305 AD. Yes, he was a very important reformer.

• 13:33Lex Fridman?

  And we'll talk about it, but let's just do this whirlwind. And hopefully there'll be automagical images somewhere overlaid.

• 13:39Speaker 01

  Okay.

• 13:40Lex Fridman?

  So 753 B.C., Rome, a small city-state is founded. And then 509 B.C., the kings are overthrown and the Roman Republic is born. 390 B.C., the Gauls sack Rome. And this, I believe, among other events throughout its history, is a formative trauma that hardens Rome's security obsession. It turns out throughout its history, people want to attack from different directions. And so you have to defend. So there's two wars, as we're actually saying off mic. There's two kinds of military operations. One is wars of conquest and expansion, and one is more defensive.

• 14:25Lex Fridman?

  And we'll talk about how the military changes throughout its history to allocate more effort to one versus the other. In 264 to 146 B.C., the Punic Wars and the survival against Hannibal transformed Rome into a Mediterranean superpower. Then- Uh, like you mentioned Caesar in forty nine to thirty one B C Caesar's crossing of the Rubicon to assassination of Caesar to the Battle of Actium. And then the civil war dismantles the Republic and concentrates power in the single ruler, Octavian, AKA Augustus, the first Roman Emperor, let's say. Yeah.

• 15:06Lex Fridman?

  And twenty seven B C Augustus founds the principate, really low key monarchy. And so officially that ends the Republic and then that begins uh twenty seven B C to one eighty A D, the Pax Romana, which is a period of relative peace and stability. And a lot of the emperors we know of, the sexy, popular emperors all come from that period. Yes. Marcus Aurelius, who I'm a big fan of from that period. Then that takes us to two eighty four A D, the guy we mentioned, Diocletian, who rebuilds the state, uh, emperors drop the first citizen mask. This perception of the way, and we'll talk about this, the persona that's presented by the state.

• 15:48Lex Fridman?

  Three twelve A D Constantine defeats Maxentius at the Milvia Bridge to become the sole ruler of the western half of the empire and then founds Constantinople in three thirty A D. East and West are split in three ninety five A D Visigoths sack Roman four ten A D. The West falls at four seventy six A D um as the last Western Emperor is deposed. And then we sort of focus more on the East Roman Empire with uh five twenty seven in the sixth century Justinian's reign. In the seventh century, Heraicus defeats Persia and then loses against the Arabs. Uh, there's the Arab conquest continuing in the seventh century.

• 16:33Lex Fridman?

  In the eighth, uh, the Arab siege of Constantinople fails.

• 16:39Lex Fridman?

  There's the Macedonian dynasty that you have an excellent book about. And then the Crusades, and then eventually leading to Constantinople falling in 1453 AD. As a person who understands the full journey of it with a focus on East Roman history, is there obvious glaring holes or incorrect things in what I just said?

• 17:08Speaker 01

  No, nothing incorrect. I would say if you wanted to produce a sort of very swift timeline of its history, it's obviously important to focus on the moments when lots of territory was lost to foreign invaders. And these are actually three main moments. There's the Arab conquests in the 630s. This is a decade, in a decade that war was lost. It is the Seljuk Turk conquest of Asia Minor, modern Turkey, in the 1070s. And that was very swift and partly reversed afterwards, but only partly.

• 17:52Speaker 01

  And then there's the Fourth Crusade, 1204, when the armies from mostly France sack, conquer Constantinople and dismember the empire as much as they could. It didn't last that long. The Romans managed to regroup and recover. But those are the three main crisis points. They are very swift, but they caused incredible damage. For all the rest of its history, it is a state and society that is generally consolidating, regrouping, and generally engaged in slow but steady economic growth, territorial expansion, a small scale but steady.

• 18:36Speaker 01

  So we can talk about this. I think it's an important thing to keep in mind about the big picture, that the defeats were swift and kind of terrible. But the most of its history is one of slow growth.

• 18:53Lex Fridman?

  There's some traumatic events that have a big impact, but a lot of the developments we'll talk about. It might seem or feel like there's a particular moment when those developments or changes in the way the government or the military is structured arise, but really it's a gradual process.

• 19:12Speaker 01

  Exactly.

• 19:12Lex Fridman?

  That's the tension we have to be constantly dancing with.

• 19:14Speaker 01

  Yeah, so as historians, this is a point of method, and it's very important. There are moments when like individuals with a great deal of power make choices that impact everybody else and have, you know, long-term consequences downstream. Constantine's conversion to Christianity, for example, right? Not something that anybody could have or did predict. Okay. Otherwise, most of the developments that we identify by specific dates, like you mentioned, 395, the division of the Eastern and the Western Empires. Those are conventional dates that we use to actually capture what is in fact a much longer process. There was no split between the two halves.

• 19:55Speaker 01

  It was one among many allocations of jurisdiction to like one sun and another sun in the east and the west. The two halves were subsequently reunited, then they kind of divided again among different emperors. It's just a process. And so we sometimes use fixed dates for what is in fact a process. Or for 76, the fall of the Western Empire. This is the last date. It's actually a very long process that took decades. So that's just something to keep in mind, that sometimes we're talking about processes, sometimes we're talking about very discreet events with long-term consequences. Yeah.

• 20:30Lex Fridman?

  Maybe an impossible question for a Roman state that lasted over 2,200 years, but is there a kind of through line, a thread, a soul that runs through the entire history of the Roman Empire? As you said, it's a slow transformation and evolution. But if we dare call the whole thing Roman, Rome, the Roman state.

• 20:53Speaker 01

  Yes.

• 20:53Lex Fridman?

  Is there some aspects, some characteristics that run through the whole thing?

• 20:59Speaker 01

  I think so, yes. By the way, you know the metaphor of the ship of Theseus? Okay, so in case the audience doesn't know, this is when there's a ship and it's at sea. And over time, like every component of that ship is replaced with some other component. So that by the end of the story, it has none of the original parts. But it's like, in a certain sense, still that ship because of the story, right? Okay, so Roman history is different from, let's say, Greek history or Christian history, right? Christian history is the story of a religion. It can be in any country, among any ethnic group. It's here, there, it's everywhere. But you still have histories of Christianity. It's the same with like, say, Greek culture or your Greek literature, right?

• 21:43Speaker 01

  It's not a function of a particular state. Ancient Greeks were famously never united in a state. But it's people who culturally accept that tradition as their kind of elite prestige culture and engage with Homer and Plato and so forth. And they can be anywhere. Roman history is not like that. Roman history is very specifically the history of a state or a political community. And so this is the community of the Roman people, the Roman citizens. And it is in gradual evolution, but at no point is there a rupture in that history such that its members would ever think that something dramatic had changed and that they're no longer part of that story.

• 22:26Speaker 01

  So in the same way as the ship I just mentioned, in other words, it's the narrative that you tell about it where the changes that take place to it make sense only when you see them within the context of that story. It's the same with Roman history. Yes, there are changes, like eventually everything changes. But it happens so gradually that it doesn't seem that way to anyone living in it. And so the narrative of the history of the Roman people is what holds all of this together.

• 22:55Lex Fridman?

  How important is it that, so you mentioned Greek culture. So a lot of my friends who are Greek are extremely proud of being Greek. There's certain cultures that are proud.

• 23:05Speaker 01

  Sure.

• 23:06Lex Fridman?

  And it's not a momentary ephemeral thing. It feels like a thing that has lasted for many generations.

• 23:13Speaker 01

  Oh, yeah.

• 23:13Lex Fridman?

  And so that is an engine that propagates through time that carries that culture forward. And so does a similar thing apply for the Roman Empire in a different way? Maybe because you say it's a political kind of community. That means a set of ideals. And we'll talk about because those ideals become even more concretized and explicit, I think, through the East Roman Empire. Because one of the things you talk about is that the citizens of the empire are kind of all connected, that they're, they are engaged in this whole sort of machinery. Anyway, that's a complicated way of asking, is there some elements that Greek pride that

• 23:55Lex Fridman?

  speak, is there some kind of Roman pride that propagates the thing?

• 23:59Speaker 01

  Oh, there totally is. You can find authors and historical agents who definitely display this or talk about it. But we don't want to make that the center of the story or the basis for any analysis because, so what you're observing in your Greek friends is also the result of modern nation building, is it's the result of modern systems of education and sort of national identities. And these are fostered and created through all kinds of media and institutions. It's just a different situation altogether. What you find in ancient republics or medieval states is more something like a consensus to be ruled, to be, to rule and to be ruled in this particular political community.

• 24:43Speaker 01

  Now, some members of it may definitely, and in fact, did have this kind of pride. I'll give you an example. So there's an ambassador in the sixth century and he's concluding a deal with the Persians. And, you know, the Persians are skeptical because Romans can't always be trusted. This guy says to them, he says, And let me just tell you, you're making a deal here with the Romans. The Romans, the name should say it all. Okay, and you get a sense that this is expressing a certain pride in like being a bearer of the Roman tradition and speaking for the emperors and the Roman Empire. I mean, that's for him, this was something very, very momentous. You find these kinds of examples, so these people exist. But I wouldn't want to make that the basis for like an analysis of how the society works as a whole.

• 25:27Speaker 01

  For the most part, it was something like a consensus where, you know, subjects or citizens, however you want to call them, they agree to, let's say, be taxed and be ruled by political authorities because of what they get in return. And there's this kind of understanding of a mutual set of responsibilities. And my concern, among other things, is to try to explain how this society held together for so long. Pride, yes, among some people, definitely. You find it in the sources, but sources are texts are written by literate, you know, usually elites. So this is a small part of the population. We can't automatically extend their attitudes to everybody else.

• 26:12Speaker 01

  So in dealing with everyone else, we have to work with different kinds of materials, different kinds of assumptions. We can't just posit that they're just proud of being Roman. They could have been, we don't know that, though. We can see other sorts of things about them, like, for example, did they pay their taxes? Did they try to rebel and leave the empire? So those are the kinds of things that I look for.

• 26:31Lex Fridman?

  Pride is one component, but it could be other explanations and factors that explain what motivates a soldier to defend the capital, for example.

• 26:41Speaker 01

  Yeah.

• 26:42Lex Fridman?

  Like what motivates a particular person to pay the taxes? And then this is something that we'll definitely talk about. But just to linger at the big picture, if the Romans from the different periods met...

• 26:59Lex Fridman?

  How different would they be from each other? Like, if I, if I brought to you, this is one of those, you know, there's like

• 27:05Speaker 01

  Yes.

• 27:05Lex Fridman?

  Blind taste tests you could do with food.

• 27:07Speaker 01

  Yes. Pepsi and Coke.

• 27:09Lex Fridman?

  Pepsi and Coke?

• 27:10Speaker 01

  Yes.

• 27:10Lex Fridman?

  If I brought you a Roman from the Kingdom period, the Republic period, the early Imperial period.

• 27:20Speaker 01

  I mean, I get asked this in a, in a, in a much more radical form, which is like, if you take someone from like around 1453, who's a Roman and a subject of this, and compare, and, and, you know, compare him or have him meet, you know, in your imagination with someone from the Ancient Republic, like, how, could they find any kind of agreement on, on, on what it means to be Roman and, and recognize each other as belonging to that polity? This is a very difficult thing to, now, I can point to a number of things that they would find eventually, and, you know, if you told them, yo, you're both Romans, you're both from this long history, now you have to find, you know, what you have in common. I think they could find things, but before we talk about those, if, if you want to get

• 28:01Speaker 01

  into it, let's just say that the question can even be posed about Romans who live at the same time. I mean, if you take a senator from the age of Cicero and someone from the slums of Rome, who's maybe the son of a slave who was brought from the east by some general a generation ago, and put them in a room and say, now you can discuss, you're both Romans, what do you have in common? They might have trouble in coming up with something, right? So, let's not minimize the sheer diversity of experiences and sort of life experiences of Romans who are living at the same time.

• 28:42Speaker 01

  The important thing is that change is always happening, and from my standpoint, this change is cumulative, so it results in a Greek-speaking Orthodox Christian Romans in Constantinople, who at first sight might have little to do with Latin-speaking, you know, non-Christians or worshiping the ancient gods, Romans from a Republic in Rome. And those are very, very different situations, and no doubt they would, they would look and seem foreign to each other, right? The question is- Why do we assume that someone like Hadrian, right, an emperor from the second century, sort of very cosmopolitan figure who travels around the empire with his Greek lover and,

• 29:26Speaker 01

  you know, writes poems and is, has a Greek beard and, you know, loves Greek culture and has much to do with someone from the Middle Republic, who's, yeah, some warrior who's chasing down cattle from the Samnites. And yet, the way we understand history is that, oh, no, those belong together, Hadrian and this ancient Roman from the fourth century B.C., but not Hadrian and someone, you know, an emperor a few centuries later, who's just like him, bilingual in Greek and Latin, who's kind of cosmopolitan, who, you know, reads the same stuff, because we posit this rupture between Roman and Byzantine.

• 30:08Lex Fridman?

  One of the ways we can try to analyze this is, for example, looking at a very specific role in society across time. So we can look at soldiers, how they saw violence, for example. That's one way. So you're making me realize that we can just take a thousand different professions and positions in society and really specifically look at what the experience of the world was like.

• 30:34Speaker 01

  Yeah.

• 30:34Lex Fridman?

  And so one of them is, is, is the view of, on violence across time. And, and then the other is the view on the role of the, the government.

• 30:49Speaker 01

  Yeah.

• 30:49Lex Fridman?

  Across time.

• 30:50Speaker 01

  That's an excellent way of putting it. So take soldiers, for example, they swear an oath. Right now, we don't have the oath for every given period. We have some approximations of it, some hints of what it contained. But we know that Roman soldiers swore an oath, like throughout all of the centuries of the empire. Sometimes they might add like a Christian formula to it, sometime before that not. But they swore basically to protect the, the, the republic or depending on what term they used, or the empire, or the emperor. And this is something that they would have recognized very quickly. Like if, if they met each other over time and said, hey, what was your oath like? And they recited it, this would have made much sense to them, right?

• 31:34Speaker 01

  Or take, for example, a woman who runs a business, right? From any century of the empire. It would have been, especially the later you go, the more so, that this woman is enabled to do this by virtue of Roman law, of certain, you know, Roman law property and inheritance and marriage, but also regulations regarding who can do what and what kinds of properties women can handle and under what circumstances. This is something that Roman women had in common that many other cultures did not. So I'll give you an example. So for example, in the 10th, 11th century, there are Jewish women who live in the Eastern Roman Empire,

• 32:19Speaker 01

  who realize that they have more rights in Roman courts than in rabbinical ones. And they take their disputes to the Roman courts. Now, the thing is that for the Romans, these are property matters, not religious matters. But for the rabbis, these are religious matters. But the Roman courts trump the Jewish courts in the empire, right? And so you ended with a situation where Jewish women have more rights than Jewish women do elsewhere because Roman law is not operative. And there you go, right? Like, these things matter, right? And that's a function of imperial law.

• 32:55Lex Fridman?

  And this would be an interesting, actually, interplay between the law and religious institutions throughout the East Roman Empire. So you argue that even though the personality of the various emperors varied, as we'll talk about, and as they're often venerated, celebrated, criticized, talked about, the late Roman Empire was projecting a persona to its citizens that was consistent throughout its history. Can you describe what you mean by this? And describe the different detailed characteristics of this persona?

• 33:30Speaker 01

  Yes. So this persona, it's what the governments or the emperor, the court and the spokesman, the bureaucracy, want their subjects to think this whole thing is about. Like, how is power being used? Why and for whom, right? And they do so in laws that they promulgate throughout the empire. Sometimes they have these laws read in church, for example, or posted publicly. They're definitely eager to have them communicated to as many people as possible. But they're also a function of imperial rhetoric. So the way you praise an emperor, the way you talk about an emperor. You find this language in petitions.

• 34:13Speaker 01

  So this is a hugely important glue for this society is that anyone could basically petition the authorities for, let's just say, just about anything. That's not technically true, but there's a lot of petitioning going on. So if you think something's wrong or you've been treated unjustly, you can petition local officials, even imperial officials, you can petition the emperor, right? And the expectation is that that petition will be read, addressed, and answered. It might not be answered in the way that you want, but it will be answered. And those responses contain this language also, right? So these are the different media through which the emperors are broadcasting this persona. And that persona is what?

• 34:56Speaker 01

  Basically, that the authorities are responsive to the needs of their subjects, that they are often accountable. In other words, they understand that they are exercising public power and that their mandate is to exercise it solely for the benefit of their subjects. They keep saying this. So renouncing any kind of private interest. In other words, "We're not doing this for our benefit," say the authorities. "We're doing this for your benefit." Also that they're proactive. So the emperors are constantly saying that "we're planning ahead. We're trying to foresee what problems you might have and we are solving them before you experience them."

• 35:40Speaker 01

  And that they are also working very hard. So hardworking. In fact, one of the cliches that they keep using is sleepless. The emperors keep saying that "I'm losing sleep over this. I'm not sleeping at night because I'm just worrying so much about your problems and how to solve them." Justinian, for example, was publicly known as the Sleepless Emperor. And not because he was a demon whose head floated around in the palace on its own. Which some people.

• 36:05Lex Fridman?

  That's a thing?

• 36:06Speaker 01

  It was a thing. That's a whole thing.

• 36:08Lex Fridman?

  But sleepers in terms of work so hard, there's no time to sleep.

• 36:12Speaker 01

  He was a workaholic. That is conceded by even his enemies. All night, he was up just hauling officials in at any old hour to talk about whatever, wars and architecture and laws and religion and theology and whatever. So the emperors are projecting this image, right? So that's what I call the persona. Tireless effort to work on behalf of subjects, to do so responsibly, to be responsive and accountable. In other words, if some of my officials breaks the law or oppresses you, I'm giving you instruments, like legal instruments, by which to hold them to account. So that's the persona.

• 36:54Speaker 01

  It's very consistent, and I think it's part of the mechanism of tying the society together. In other words, if subjects think that their emperors are like this, they're more likely to agree to the consensus of essentially paying taxes.

• 37:10Lex Fridman?

  And you draw this distinction between rhetoric and action, what the authorities say and what they actually do. So when you say persona, in the modern times, some of that could be reframed as propaganda, for example. And propaganda implies that the rhetoric, that there's a big gap between the rhetoric and the action. And one of the things you said you took away from reading Machiavelli is that we should judge people not by what they say, but by what they do. So how much of the Roman Empire's government of what they espoused was merely rhetoric and how much was true in how they acted?

• 37:49Speaker 01

  Yes. This is a key lesson I took from reading Machiavelli. And I found this a very insightful way of thinking about politics. And I would recommend that anybody kind of practice this way of looking at the world. People and states and powerful people can say anything they want to. At the end of the day, what matters is what they actually do. And this doesn't mean that what they say is irrelevant, even if it's discordant with what they do. But nevertheless, in the case of the East Roman State, so my research suggests that the emperors and the authorities were generally sincere in what they said.

• 38:31Speaker 01

  In other words, I have found that they generally did what they said they were going to do overall. Not perfectly, obviously. And of course, these are human beings we're talking about. The human societies, there was a lot of corruption and you name it, abuse, of course, of course, there is. But overall, I think that there was a sufficient level of understanding that the emperors are in fact doing this. And they were actually incentivized to do this. We can talk about how, because they were also in a pretty vulnerable situation, too. So they needed their subjects to be relatively content on this front.

• 39:12Lex Fridman?

  Isn't this surprising to you? So from the outside of point of view, Roman emperors, even in the East Roman Empire, technically have a lot of power.

• 39:25Speaker 01

  Yeah.

• 39:26Lex Fridman?

  You can even say, in some cases, absolute power. And yet, they seem to be awfully worried.

• 39:33Speaker 01

  Yeah.

• 39:33Lex Fridman?

  To make everybody in the empire happy. What explains that? Like, what explains the small gap between rhetoric and action in the East Roman Empire?

• 39:45Speaker 01

  A number of things, but ultimately, it is that there is no right to the throne. And this is a function of the Roman matrix of politics here. In other words, so here's a bit of a paradox. What we call the Roman Republic was the most imperialistic phase of Roman history. This is when the Romans did most of their conquering. What we call the Empire is much less imperialistic in this way. That's much more defensive in its approach, right? And yet, our terms are a little mismatched in that way. The Empire is more a function of the, that it has an emperor rather than it is engaged in imperialism.

• 40:29Speaker 01

  And that emperor emerged out of the Republic. But emerged out of the Republic in a very strange way. In other words, not as a dynasty that created the state. So for example, if you think of the Ottoman Empire, many other empires, they, the whole thing existed because this dynasty engaged in conquest and was successful in creating the state. And so the dynasty was like at the heart of the state. But that's not at all the case in the Roman Empire. The emperor is a figure who emerged within a Republic. And in order to create peace after the civil wars, those emperors had to, for a long time, kind of pretend that they were not what they really were.

• 41:13Speaker 01

  And by basically, you know, continuing to flatter the idea of a Republic that is, you know, that has a first citizen, maybe. Oh, no, no, I'm not a king. I'm just, I have this office and that office and that office, whatever the Senate has given me. Now, we understand that's a facade, but the fact that they had to create this facade at all is very important.

• 41:33Lex Fridman?

  Can we actually just linger on that? I mean, how much of this, because you said they had to create this facade?

• 41:38Speaker 01

  Yeah.

• 41:39Lex Fridman?

  Did Augustus, who started the whole thing, the first emperor of Rome, did he have to act that way? Because he kept acting like he's not an absolute monarch. And he could have gone hardcore, destroy the Senate, just full hardcore rule dictator.

• 42:02Speaker 01

  How does he govern then?

• 42:04Lex Fridman?

  So, so he wants to be an effective governor? And he also wants to not be overthrown?

• 42:09Speaker 01

  Exactly. Because, you know, just because you ended one civil war doesn't mean that there's not going to be another. You have to create a consensus such that people don't want to have another civil war. If he did what you said, which he, in theory, could have done, but that would have just led to more wars, right? So the problem is that the emperors, even those who come to power through violence, they can't prevent other people from trying to come to power through violence. Because, like I said, no one has a right to the throne.

• 42:38Lex Fridman?

  We should also say one more thing where. Day I carefully say this, but it seems like riots and civil wars is a feature, not a bug of the system.

• 42:52Speaker 01

  Yes.

• 42:52Lex Fridman?

  This is a different thing that we have to the modern day is because the threat of a civil war, a violent civil war where you overthrow the government and there's just a lot of

• 43:04Speaker 01

  Yeah.

• 43:04Lex Fridman?

  Death and struggle for power is always a threat. That's another incentive that I guess the stick, not the carrot, but the stick for the emperor to behave.

• 43:15Speaker 01

  Yes, it's the main one. In other words, just take the, the thousand years that I study. There's something like 120 civil wars. These are usually very swift. They're over quickly and they're never about ideology. So they're not like modern civil wars. All right. It's about slavery or the rights of kings or whatever. No, no, no. They're solely about who has the power. All sides have the same ideology. They talk about, you know, the responsibility of government in the same way. Right. They're just competing over who's the best man to do the job. Right. And so, once you have that situation, and it might not be a civil war, it could be a palace coup, it could be a kind of fighting in the capital, something like that.

• 44:00Speaker 01

  Once everyone's taken their side and, and you have a winner, that's the emperor.

• 44:06Speaker 01

  And you, you often overthrow the previous regime. I'll give you some statistics, something like 46% of the emperors of Constantinople are overthrown through violence. 46%. And that's almost half. Right. So that's a huge, that's a huge number, which means that every emperor is vulnerable and insecure and they know it. Right. So what they have to do is make sure that that doesn't happen to them. And the way to do that is not by arresting and executing everybody you think might be a threat or just generally behaving like a, you know, a Caligula or Nero, that will just get you killed. Like they know this. So the best way to avoid that fate is to actually do the things that will make people

• 44:49Speaker 01

  happy so that they don't support a rebel if a rebel decides to appear. And sometimes rebels would appear. There's a kind of convention in Constantinople. Like if you, sometimes you, you think, hmm, that emperor is pretty unpopular and I think I can overthrow him. What you would do is

• 45:06Speaker 01

  You would march down the Center Boulevard. And you'd have your people just call the populace of Constantinople out to rally, maybe go to Hagia Sophia, the church, and just create a big crowd and call for the deposition of the emperor. And maybe that would happen. And sometimes it did, and sometimes it didn't. And the rebel, or wannabe rebel, would sort of proceed down the boulevard, and people would just gradually disappear. And then he'd be left alone and go up to Hagia Sophia as seeking asylum. Right? So that's a bid. That's someone making a bid for the throne, and it just goes disastrously bad. Other times, the people come out because they hate the emperor, and they drag the emperor

• 45:49Speaker 01

  out and cut his nose off or whatever. So emperors are constantly trying to prevent that from happening, and the best way to do that is for goodwill.

• 45:59Lex Fridman?

  I'm trying to load in that kind of world because it's a different world than we live in today.

• 46:06Speaker 01

  Yes.

• 46:07Lex Fridman?

  There's a constant inner workings of policy development inside government.

• 46:13Speaker 01

  Yes.

• 46:14Lex Fridman?

  But the check on power is like literal, like, "We will murder you."

• 46:19Speaker 01

  Yes, it depends on the period. Sometimes murder you, sometimes blind you, sometimes cut your nose off. But there were periods-

• 46:26Lex Fridman?

  Thank you for the nuance.

• 46:28Speaker 01

  No, there were periods that were more civilized. We'll just basically, you'd get retired to a monastery.

• 46:32Lex Fridman?

  Right.

• 46:33Speaker 01

  Okay. You're right. So here's what elections do. Elections give a government a mandate for, I don't know, four or five years. And during that period, you may be unpopular, but you're legitimate, right? Because of the institutions. Whereas in Constantinople, we don't have those kinds of institutions. We have instead an ongoing referendum. We just call it a perpetual referendum, right? And in fact, the emperors are, they're conducting opinion polls, in a sense, because they appear in public. They appear in public, everyone is expected to cheer and chant acclamations, right? Like slogans, right?

• 47:14Speaker 01

  So you have 100,000 people in the hippodrome, all chanting, "Worthy," or "Many years for you, Augustus," or something like this. And if that happens, it's great. But if you appear in the hippodrome, and people are sullen, or the chanting is a bit tepid, or if they're booing- Then you know something's wrong, right? So you've got to find out what's wrong. It could be something like the grain supply is, you know, not working or whatever. And so emperors are desperate to fix those problems.

• 47:43Lex Fridman?

  And the Hippodrome is this big gathering place in Constantinople, which I guess a lot of people gathered at and did this kind of cheering or not cheering based on policy and whether the emperor is popular or not. This was democracy. I apologize to use that term, but in our conception of what that means, because what do we mean by democracy in the modern day? Is that the people somehow have a connection to who leads and how they lead. And this is, the Hippodrome was that connection between the people and the leaders.

• 48:19Speaker 01

  Yes. Now, we can talk about modern democracy if you, if you want. That's, I have, I have my own views about modern democracy. And, you know, how it works and how it doesn't. And anyway, whether it is democracy, in fact, because there are other models of democracy, like ancient Athenian democracy, which is a whole other thing. But you're right. It's not just in the Hippodrome. It's wherever people assemble in large numbers. So this could be military mustering grounds, right? So the army, the army is also the Roman people in a way. And in some cases, the most decisive part of it, right? So if an army gathers together and they decide they want a different emperor, that's serious. And that can happen out in the provinces, too. That doesn't necessarily have to happen in Constantinople.

• 49:04Speaker 01

  There's also a yisofia. So the people gather in the church or they gather in public spaces like the Forum of Constantine. So this can happen anywhere where a large number of people can gather. And it's, I don't know if you want to call it a democracy as such, but it is definitely a form of popular, let's say, consultation and a testing of consensus. I'll give you another example. So in the 1190s, the emperor, and it's Alexius III.

• 49:36Speaker 01

  He's being threatened by the German emperor. German emperor is basically, you pay me a bunch of money or I'll invade. Just straight up extortion.

• 49:43Lex Fridman?

  Yeah.

• 49:43Speaker 01

  And Alexius decides, okay, I'm gonna, I'm gonna gather this money. I'm gonna impose these taxes. And he gathers the people in the hippodrome. And he says, you know, we're gonna have the German tax. He called it the German tax. And there's such an uproar in the hippodrome against this that he was like, uh, that wasn't my idea. I don't know where that came from. No, never mind. We're not gonna have the German tax. Unfortunately, the German emperor died and nothing ever happened. But it gives you a sense of how emperors like literally can backtrack when they see that the people are against something in a matter of policy, right? Like tax policy. So, yeah, there, there, there was this give and take. So institutionally, the emperor might look absolute, as you called him earlier.

• 50:27Speaker 01

  In practice, no. No, the ones that did that didn't end well.

• 50:33Lex Fridman?

  And we should say, going to perplexity here, the hippodrome of Constantinople was the main stadium and social center of the Byzantine capital. Used primarily for chariot racing and imperial ceremony and today survives in Istanbul's Sultanate district. And the reason I looked this up, I wanted to see how many people. Shaped as a long U-shaped race course with a central barrier and tiered seating. It may have held from roughly 30,000 up to 100,000 spectators. Though exact capacity is debated because archaeological remains are limited.

• 51:11Speaker 01

  Yes.

• 51:11Lex Fridman?

  That's a lot of people.

• 51:12Speaker 01

  30,000 is definitely a pretty underestimate.

• 51:15Lex Fridman?

  Yeah.

• 51:16Speaker 01

  The hippodrome is still there. I mean, you can see it from like satellite photos. The shape of it is still there. And actually, some parts of the built, the Svendani, the sling around the southern side is still there. You can walk around it. And it's right next to the palace. In other words, emperors didn't have to go far. Now, sometimes there are events for replacing an emperor. So say the emperor dies in his sleep and there's no heir. This happens in 491, for example. And so the people gather in the hippodrome in order to have a discussion with the court about whom to appoint. Now, in those kinds of contexts, it's entirely possible that there are people also in the arena, like not just in the stands.

• 51:58Speaker 01

  I think some military units might have just been arrayed there rather than in the stands. So you can get more people than what we project might fit in the stands because they're not having the races on that day.

• 52:09Lex Fridman?

  We should say, so like, I think the thing that was emphasized in the first paragraph is the athletic events and the entertainment events, right? Like the imperial ceremony, but there is a sort of a political gathering was also popular. The hippodrome was not just for sport. It was where emperors appeared before the people, where acclamations, public punishments, and political demonstrations took place, and where the rival circus factions, blues, greens, reds, whites, became powerful social and sometimes paramilitary forces. And this goes on and on and on. So this is a place

• 52:45Speaker 01

  Oh, it's a very important place, yeah.

• 52:46Lex Fridman?

  For the people to speak to the leader.

• 52:48Speaker 01

  Yeah, vent sometimes.

• 52:50Lex Fridman?

  Yeah.

• 52:50Speaker 01

  Even insult them.

• 52:51Lex Fridman?

  Yeah, this is fascinating. I mean, it's human civilization has converged towards a mechanism that has clearly worked because for the empire in the East stood for a thousand years. So it's fascinating. We as humans throughout our history, we were trying to figure out, okay, how do we figure out how to govern large collections of humans in a way that they're represented, in the way that they don't riot, they don't rebel?

• 53:25Speaker 01

  Yes.

• 53:27Lex Fridman?

  In the way that we flourish together as a people, all this, all this kind of stuff. So this is a real, the East Roman Empire is a real study of something that seemed to have worked. There's lessons there even for the modern times, I think. And modern times, again, is very early.

• 53:46Lex Fridman?

  Human civilization.

• 53:47Speaker 01

  From a certain standpoint, yes, we are still early in.

• 53:51Lex Fridman?

  Trying to figure it out.

• 53:51Speaker 01

  Trying to figure it out, yes. Now, mind you, I'm not advocating for this type of social organization and government. What I'm trying to do as a historian is understand how and why it survived. And also to find the ways that it worked, because it did work. We know that much. We have to start from that. It survived. It was resilient. There was a lot of, you know, give and take in the exercise of power. And I want to understand the mechanisms of that.

• 54:20Lex Fridman?

  So if we can, before we go to Emperor Constantine I and the founding of Constantinople, can we look at some maybe seminal events that led up to some of the topics we'll be talking about? So one of them, maybe tell me if this is not as interesting as I think it is, but the Edict of Caracola in 212 AD. So this is where you described that, starting with Augustus in the early imperial period, government saw itself as a protector of the Roman citizens, which is a minority of the people living in the Roman Empire. It doesn't consider the provincials.

• 55:04Lex Fridman?

  And then you described that the Edict of Caracola, that extended full Roman citizenships to basically all free inhabitants of the Roman Empire. So what is it? Why was it done? Why is it important? And how did it change the Roman Empire?

• 55:24Speaker 01

  Right. I agree with you that this is, in fact, a very important. It's a real turning point, in a sense, but it also is part of a process. So for various reasons, the Roman polity tended to bestow its metropolitan citizenship, that is, Roman citizenship, on its allies and eventually in time on many people that it had conquered. And it had various mechanisms for doing so. It could bestow block grants. Sometimes it allowed its generals to bestow citizenship on people they thought were, you know, would be necessary players for controlling local societies.

• 56:07Speaker 01

  Sometimes they even allowed foreign cities to, like, non-Roman cities, to decide who would get Roman citizenship by basically electing them to certain kinds of offices. Like, they outsourced a lot of this. And so you have, over time, the steady growth of a Roman community of citizens who are not all in Rome and who are not all of Roman origin, whatever that means, but they were not descended from people who were from Rome. And this proceeds, you know, it expands, it expands, it expands. By Caracalla's time, so early 3rd century AD, we can estimate that maybe at most a third of the free citizens of the empire are Roman citizens.

• 56:50Speaker 01

  Everyone else has local citizenship, like you're Alexandrian or Athenian or whatever. And you're subject to those laws. This emperor, Caracalla, now that's his nickname. His reigning name is Marcus Aurelius Antoninus. So just like Marcus Aurelius, it's the same name two generations later.

• 57:08Lex Fridman?

  Some badass names for emperors, by the way. I don't know if it's chicken or the egg, but just some epic names.

• 57:15Speaker 01

  They've been remembered that way, and so we read that back into the name. Absolutely, yes.

• 57:20Lex Fridman?

  But anyway, Caracalla.

• 57:21Speaker 01

  Yeah, so he issues this edict in 212, called the Constitutio Antoniniana, named after him. Some people at the time called it the Divine Decree, which basically extended citizenship to everybody. Now, we don't know exactly why he did so. We can guess the reasons that he said he did so. And this was to, for religious reasons, in other words.

• 57:44Speaker 01

  He wanted people to go to the temples and pray and give thanks to the gods for his survival out of a coup, which is whatever. And it's possible that this was a, there was some kind of religious motivation here, and he wanted everybody to do so as Roman citizens, to honor the Roman gods and something like that. Other historians at the time said he did it for tax reasons. We don't know exactly. There might even have been a kind of ideology of a unified community across the empire playing in his, if not in his mind, in that of the gibbers, that is, the legal advisers that he had. So that's possible.

• 58:28Speaker 01

  But less interesting than his motivations, more interesting is our, the consequences of this and what it tells us about the Roman community. So imagine a situation where, like, no modern empire has ever done this, really, right? What's significant about the Roman case is that not only did they extend citizenship to everybody, but they meant it. This is something that had teeth. In other words, it meant that the rights and opportunities that were available to Roman citizens, say, in the Roman Senate at Rome, are now available to everybody.

• 59:06Speaker 01

  And within a generation, you have a situation where, like, all of the emperors are provincial, right? All the most powerful people in the empire from the provinces.

• 59:18Lex Fridman?

  This is like mind-boggling, mind-blowing. This is incredible.

• 59:21Speaker 01

  Yeah.

• 59:22Lex Fridman?

  The fact that the Roman Empire was able to do this, and it stuck.

• 59:26Speaker 01

  They did it and they meant it.

• 59:27Lex Fridman?

  And they meant it, they implemented it, it was real. That tells you, that's an important thing that tells you a lot of information about the populace of the Roman Empire. That the fact that it stuck, that the government meant it, that the system encouraged, incentivized the government to mean it, it's incredible.

• 59:48Speaker 01

  Yeah, and there's a law of citizenship, and it, basically, it says something like, anyone born within the Roman Empire is a Roman citizen. And the Roman jurists and policymakers who were behind this had some very interesting ideas about, you know, creating this kind of community. Look, like, imagine if, I mean, it's almost impossible to imagine, but the British at the time of the peak of the empire bestowed British citizenship on everyone, including in India, and like suddenly made positions of power in London available to people from India, like, including the throne. Like, it's just unthinkable. And that has to do, you know, with race and colonialism and all kinds of things, right? But not in the Roman Empire.

• 1:00:32Speaker 01

  So we have a situation where the emperors are all from the provinces, the most powerful officials are all from the provinces. And so a century later, when Constantinople is created, this is, it's created, like, in the Bosporus, so like where modern Istanbul is, in the Eastern Roman Empire, it's created within a pre-existing Roman context, right? It doesn't bring Romanness to the East, it's already there. And so it's not such a leap to create a center of Roman power in the East because of that.

• 1:01:07Lex Fridman?

  And you've helped put together a book on the history of intellectual thought in the East Roman Empire, but this is the interesting thing here, and I can ask that many times, but let me ask it here also, is the great man, the great woman view of history, were there like Thomas Jefferson or those types of characters in the meetings as they're executing on the edict or developing the edict? Is that important? Or is it more about the system and the culture and just, uh?

• 1:01:36Speaker 01

  Yeah.

• 1:01:37Lex Fridman?

  Was it, how important was it? Because this seems like a revolutionary idea, and when we think about the American Revolution and the founding documents, it seems like a few individuals were really critical about the wording of things. And then words matter because those words create the reality and then it propagates through time.

• 1:01:56Speaker 01

  For the edict, I suspect that yes, there were a few people who were behind it, and quite possibly jurists, that is, Roman legal scholars. And 212 is in an age of very important Roman legal scholars, Olpian, for example, and others. But we just don't have those. We have minutes of the meetings for the American Revolution. Not only do we not know who was in the room, we don't actually even have the whole edict. We have a papyrus fragment. This is a piece of ancient paper that's mostly torn and mutilated. And we have like a bit of a paragraph from it in Greek, not even the Latin original. And it's kind of torn, but it actually preserves the key clause. Right?

• 1:02:39Speaker 01

  And that's, that's all we have of the original. We have contemporary sources that mention it. We have legal documents, but nothing like a, like we can talk about the people involved in it. Or even how it was immediately implemented. Like suddenly we know everyone in the provinces, like there's this explosion in a number of people called Aurelius, because that was his, his Roman family name. And so when you acquired citizenship from that edict, you became an Aurelius. Right? And there are lots of Aurelius suddenly all over the place. Like, we can see it immediately.

• 1:03:15Lex Fridman?

  Yeah.

• 1:03:16Speaker 01

  But we can't actually see the implementation.

• 1:03:19Lex Fridman?

  But your instinct says that it was very, individuals were very important in the development of that idea and execution of it.

• 1:03:27Speaker 01

  Probably, yeah, yeah. Even though it's part of a long-term process of expanding Roman citizenship, this was a, an explosion, not just an expansion.

• 1:03:36Lex Fridman?

  And then you said that one of the important aspects about this edict is that giving equal rights to provincials was one of the things that helped deal with the, with the crisis of the third century and was the thing that, I think you said, quote, "sapped discontent from the relevant populations", which then minimized the probability of outprisings.

• 1:04:00Speaker 01

  Well, now, that's a very long-term process.

• 1:04:02Lex Fridman?

  Yeah.

• 1:04:02Speaker 01

  Now, the third century is chaos, there's a crisis, it's a mess, right? So what, what follows the edict is... Quite a few decades of unrest.

• 1:04:13Lex Fridman?

  Okay, let's put it mildly. Let's talk about the crisis of the third century, where 26 emperors were murdered in a period of 50 years.

• 1:04:24Speaker 01

  Yes, it's tremendous instability.

• 1:04:26Lex Fridman?

  So there's civil wars nonstop. Almost all of these emperors were generals and almost all were murdered by their men. So civil war was the norm, hyperinflation, economic crash, plus there's a plague from 249 to 262 AD, which is a pandemic, possibly smallpox or Ebola. It killed up to 5,000 people a day in Rome alone, devastating the tax base and army recruitment pool. And the empire fractured into three pieces, but then Emperor Aurelian miraculously reconquered them in a period of five years. So there's a lot

• 1:05:10Lex Fridman?

  of chaos. It deserves the name of the crisis of the third century.

• 1:05:14Speaker 01

  It's a perfect storm. Yeah, I mean, you have a crisis of imperial legitimacy, basically the armies proclaiming emperors left and right. In an odd sense, ironically, this is in part because there are now a lot more stakeholders in the Roman trident, right? There's all of these provincial armies and they're appointing their generals as rival emperors. But you also have a serious uptick in foreign invasions. In the north, you have the creation of the Sassanian Persian or Iranian empire in the east, and this was very, very bellicose. So lots of foreign defeats, armies are defeated by, you know, like, quote, barbarian enemies. You have eventually inflation and you have plague.

• 1:05:59Speaker 01

  And so, under the pressure, right, of all of those forces, it almost fell apart. Now, it didn't actually. Inevitably, there are also historians who downplay the crisis, of course, but like, and legitimately so, right? We must push back against every of these characterizations.

• 1:06:16Lex Fridman?

  26 emperors died, bro.

• 1:06:18Speaker 01

  That's just the emperors. That's just the emperors. We're no, we should be.

• 1:06:22Lex Fridman?

  I'm sorry, in 50 years.

• 1:06:24Speaker 01

  Yeah.

• 1:06:25Lex Fridman?

  Every other year, emperor dead.

• 1:06:26Speaker 01

  Yeah.

• 1:06:27Lex Fridman?

  Civil war.

• 1:06:28Speaker 01

  That's political instability at the top, right?

• 1:06:31Lex Fridman?

  Right, that's not.

• 1:06:32Speaker 01

  What are the lives of most people? So if you go to Egypt, for example, which is kind of out of the, right? What's going on there? How are people living there? And we can see how people are living in Egypt because we have all these papyri documents from Egypt. And for the most part, they don't seem to be experiencing a crisis.

• 1:06:49Lex Fridman?

  I mean, this is something you talk about, Constantine, as we'll get to him, is one of the most murderous leaders in all of human history, if you consider his own family. But if you're living in the provinces, you know, there's, he's.

• 1:07:06Speaker 01

  Oh, yeah, yeah.

• 1:07:07Lex Fridman?

  He's not that murderous.

• 1:07:08Speaker 01

  No, no, no, he's perfectly fine.

• 1:07:09Lex Fridman?

  So it's very important to actually remember about what the actual experience of the average citizen of the empire is like.

• 1:07:16Speaker 01

  Yes.

• 1:07:17Lex Fridman?

  Fair. Okay, so, but how, maybe there's more we could say about the crisis? And then, of course, the crisis is in part resolved by Diocletian as he does a hard reset on the structure and the Roman system of government. So maybe you could speak a little bit more to the crisis that's important for us to understand and how Diocletian solves the crisis in 284 AD.

• 1:07:41Speaker 01

  Right. So again, these are processes rather than specific events.

• 1:07:45Lex Fridman?

  Sure.

• 1:07:46Speaker 01

  So for example, you mentioned that the empire kind of breaks into pieces.

• 1:07:50Lex Fridman?

  Yes.

• 1:07:50Speaker 01

  And we have what's called sometime the Empire of the Gauls. Gaul are modern France and sort of Britain for a while are, for a decade and a half or so, are kind of like this little separatist empire. So what's interesting about that is that this was not an attempt to break away from the empire. In other words, it's not some discontent provincials who are just tired of Roman rule and want to break away and do their own thing. No. This is actually just a, it's an attempt by provincial generals to take the throne and to rule the entire empire. It doesn't work. They get only as far as the provinces that they take.

• 1:08:31Lex Fridman?

  Mm-hmm.

• 1:08:32Speaker 01

  And the only way that they know to set up a state is to make it a Roman state, right? Like, that's the total of their political imaginary is like, well, we're just gonna do a Roman thing here. And maybe we'll get, you know, we'll reunite the empire ourselves, or as happened Aurelian, that is, someone from the other side will reunite the empire. But it's always a Roman model. Like, there's, it's almost like there's no alternatives by this point. So that's interesting. What Diocletian does essentially is, the way I characterize it sometimes is that he turns the problem into its own solution. In other words, the problem is too many emperors or wannabe emperors. Because there's just more

• 1:09:16Speaker 01

  going on. Like, one emperor can't deal with all these problems along the frontiers, with all the political problems. So what he does is he deputizes some of his colleagues, people he was on very good terms with from the army. These are all Illyrians. They're from, by the way, for a few centuries, the emperors are all from this region of the former Yugoslavia that's the size of Scotland. That's where they all come from.

• 1:09:37Lex Fridman?

  What explains that?

• 1:09:39Speaker 01

  The army.

• 1:09:39Lex Fridman?

  Ah.

• 1:09:40Speaker 01

  These are military men. Sometimes hard-drinking military men.

• 1:09:43Lex Fridman?

  Yeah.

• 1:09:44Speaker 01

  Very good at their job. Like Aurelian you mentioned, right? So there's a series of Illyrian emperors who restore stability. And the reason why there's so many Illyrian emperors is because they work their way up through the ranks of the army. And, you know, the regions of Yugoslavia at that time are sufficiently, you know, economically underdeveloped that there's a strong incentive for For young men to go join the army because, you know, it's a, it's a living. And so the Lyrians become like kind of the backbone of the Roman army and they're described as these, you know, tough Roman conservative types. I mean, these are, you know, these are, these are tough military guys.

• 1:10:27Speaker 01

  I say that to draw a contrast between, say, Hadrian, whom I mentioned earlier, you know, who was a much more sophisticated, artsy, poetic, cosmopolitan emperor. Also a hard ass, you did not want to mess with Hadrian. But these guys from the third century are military men through and through, like their whole careers are in the army.

• 1:10:47Lex Fridman?

  Yeah.

• 1:10:48Speaker 01

  And they have like the military stubble.

• 1:10:50Lex Fridman?

  Yeah.

• 1:10:50Speaker 01

  They've got these thick necks.

• 1:10:52Lex Fridman?

  Yeah.

• 1:10:52Speaker 01

  They look angry, they've got their hands on their swords. Like, they're not projecting an image of sort of calm and sophisticated, you know,

• 1:11:01Speaker 01

  you know.

• 1:11:01Lex Fridman?

  So so military men, military men from earlier.

• 1:11:04Speaker 01

  Yep. So Diocletian gets a gang of them together. They eventually, there are four. We call this the tetrarchy. And he basically allocates them to various, this wasn't any kind of hard division of the empire. Basically, it was a, it was a collaborative project. They each went wherever they were needed.

• 1:11:25Lex Fridman?

  Was, is it fair to say that there was four administrative zones? He allocated each one to a zone?

• 1:11:31Speaker 01

  Broadly, I'd say more military zones. So the administration tends to operate it kind of humming along in the background, wherever these emperors happen to be, right? This is a, we're talking about a period of big government now. So Diocletian creates a larger government, possibly a larger army. And in order to pay for that, you need more systematic and effective taxation, which means you need more census, you need more bureaucracy, you need more collect, you know? So it is an era of bigger government.

• 1:11:58Lex Fridman?

  So just to linger on that point, is it fair to say that Diocletian created the deep state, quote, deep state? So the tax collectors, the logistics, the thing that you've kind of hinted at, which is the separation of the civil and the military layer of society.

• 1:12:15Speaker 01

  So the concept of a deep state, I've had discussions about that with experts who work on the idea of the deep state. And I'm not sure that I would characterize the Roman Empire that way, in part because while you do have big government, you do have bureaucracy, you have, you have bureaucrats who are buried in various echelons and, you know, nobody knows exactly what they're doing and things like that. I have not come across the idea of some sort of sinister elements, you know, who are working within the administrative apparatus to undermine the emperor.

• 1:12:51Speaker 01

  Like, from a distance, occasionally, you might get glimpses of this kind of thing. Diocletian, for example, once complained that, "Nobody ever tells me anything." In other words, like, he's so removed, in part, from the realities of what's going on on the ground, that he felt sometimes he'd lost touch. But I don't find this kind of idea of undermining imperial power from within the bureaucracy.

• 1:13:14Lex Fridman?

  Yeah, I think one of the ways to explain that is because, so, you know, in the modern-day "democracy" in quotes, there's a kind of temporary nature to the leader at the top. So it incentivizes a deep state to form. That, so the deep state thinks of themselves as a thing that propagates long-term periods of time. And then the leader is a very ephemeral, short-term thing. With an emperor, technically, you can go for a long time, so it's best to be integrated deeply. The bureaucracy should be integrated with the leader. Yeah, it makes sense.

• 1:13:48Speaker 01

  Yep. Also, in modern social thought or fear is that the deep state might be undermining, say,

• 1:13:58Lex Fridman?

  undermining, yeah.

• 1:13:58Speaker 01

  the democracy itself, rather than, right, rather than, it can cut both ways.

• 1:14:02Lex Fridman?

  But there is a bureaucracy. There is a big government.

• 1:14:06Speaker 01

  Absolutely.

• 1:14:07Lex Fridman?

  There's a big machinery.

• 1:14:08Speaker 01

  Yeah, compared to before.

• 1:14:10Lex Fridman?

  Before.

• 1:14:11Speaker 01

  Yes. So Diocletian creates these larger bureaucratic structures, and these are the ones that define the society that I study. So as a specialist, I focus on the period after him, mostly. But he implemented those to solve a lot of these problems. He was mostly successful. So in terms of generating revenue from a much more troubled and kind of precarious situation, it may sustain large armies and putting down these rebellions and usurpations. And he was generally successful at doing that. So he created the model that they kept for the next, well, three centuries or more.

• 1:14:53Lex Fridman?

  But a lot of the elements of that model lasted even beyond that, right?

• 1:14:58Speaker 01

  Yeah, like universal taxation. I'll give you an example. Up until then, Italy was exempt from taxes. Italy was the land of the conquerors. The conquerors don't pay taxes to themselves. The conquerors live off the taxes that others pay, right? So Italy was this big tax haven, right? Diocletian, Galerius, you know, his guys, these guys are from Illyria. They're from the Balkans. Like, why is Italy tax-free exactly? You know, that doesn't make any sense. It's a very, very wealthy, prosperous part of the world. And so, no, they tax Italy. So now, like, not only do all Romans have the same citizenship and the same law, they all have the same tax system. And the Diocletianic tax code, as it were, it's not a code, it

• 1:15:40Speaker 01

  sounds like a flat tax, which for us sounds regressive. But by those standards, by the standards of that time, it's actually kind of progressive in a way. It means that, like, even elites paid like the same, right?

• 1:15:55Lex Fridman?

  So how much of all of this, everything we'll talk about in the coming centuries is all about taxation?

• 1:16:01Speaker 01

  I think it's huge. Taxation is the heart of it.

• 1:16:05Lex Fridman?

  So, I mean, the functioning, the success, the flourishing of a society, the way the government works, the way the people are represented, all of it has to do with the civil wars and everything. It feels like taxation is at the core.

• 1:16:18Speaker 01

  Yes. Yeah. If you asked me to put my finger on one factor, it would be that.

• 1:16:23Lex Fridman?

  So the taxation system, that feels like the early framework for the East Roman Empire.

• 1:16:30Speaker 01

  It did create a more sort of homogeneous framework, for sure. By the end of the third century, it's pretty much in place. What Diocletian does is a universal census. And this is continued by his successors. So every taxable asset in the empire is censused. And so you can now start to have a budget.

• 1:16:52Lex Fridman?

  Now, there is some element, and then you push back against that, some element of Diocletian where he legally limited social and class mobility.

• 1:17:02Lex Fridman?

  In part for the taxation system, it made it, in many cases, illegal to move and illegal to quit your job. For example, as I read, to guarantee the food supply and land tax, farmers were legally forbidden from moving away from the land they worked. So the state always knew who to tax. And then for soldiers, sons of veterans were legally obligated to serve in the army to maintain troop numbers. You argue that these were tax enforcement mechanisms, not a rigid caste system. And so in practice, the empire remained a society of high mobility.

• 1:17:42Speaker 01

  This is a complicated matter.

• 1:17:44Lex Fridman?

  Yeah.

• 1:17:45Speaker 01

  So let's talk, for example, about soldiers. It's probably the case that most soldiers' sons were expected to succeed them. Like, most professions, where you have an apprenticeship, the son will usually succeed, right? There are a number of other professions that were kind of guild-like in nature, like, for example, shipping, where there were considerable assets involved in order to secure contracts for insurance purposes for the ships and so forth. And it made sense for those assets to be, you know, passed from father to son. In other words, and with them comes the obligation to continue in that line of work.

• 1:18:28Speaker 01

  Some of these things are inherently sort of hereditary, and I don't think most people would have objected to it. The farmers is probably the only case where it might have actually involved some coercion. There was a category of farmers, and we don't know how many of them, who were, for fiscal purposes, bound to the land. This doesn't mean they couldn't leave the land physically and I was preventing them from leaving, but they were fiscally responsible for providing the taxes or rents or whatever, because the state wanted to have a secure revenue stream from, say, those lands. And if, anyway, it's one of these complicated situations. This did create some limitations on those people.

• 1:19:13Speaker 01

  And it's a topic of current research, these bound farmers, as it were, who are tied to the land. It's more of a, you know, someone put it that, you know, most of the time it's people who own the land. And in this arrangement, it's the land who owns, that owns the people.

• 1:19:29Lex Fridman?

  But you're saying the bigger picture thing is that there was mobility.

• 1:19:33Speaker 01

  Oh, there's considerable mobility.

• 1:19:34Lex Fridman?

  Class mobility and fiscal mobility. Oh, yeah. Meaning people moved a, and we'll see this as from the west into the east and Constantinople and all this kind of stuff.

• 1:19:42Speaker 01

  Oh, yeah. There's tons of mobility.

• 1:19:44Lex Fridman?

  Yeah.

• 1:19:45Speaker 01

  No, no, this is not a society where people are bound, really. We, like, we don't find anybody who's, who's like, I, I really don't want to be a soldier, but my father was a soldier and I'm obligated to be one. Like, we just don't hear those kinds of complaints of people who don't want to be a so, why wouldn't you want to be a soldier in the Roman Empire? I mean, it's got tremendous perks.

• 1:20:04Lex Fridman?

  Right, right.

• 1:20:05Speaker 01

  Yeah.

• 1:20:06Lex Fridman?

  So can we just linger on the, why is it that Diocletian was able to stabilize that empire? It's like, you know, the crisis of the third century really threatened to tear apart everything. So why did some of these things that we talked about stabilize?

• 1:20:23Speaker 01

  Well, Aurelian had already united the empire territorially. So this is right before Diocletian. And what Diocletian did was put in place a system that reduced the number of rebellions. Simply by having four big guys with four armies, they managed to put out all of those fires, or most of them. And once you have stability, and he also beat the Persians, I mean, Galerius did, so starting to beat back foreign invasions, that creates a framework for economic stability. People need... To, you know, if they're going to invest in like land reclamation or expand production, they need to know that foreigners aren't going to come rampaging through marauding,

• 1:21:05Speaker 01

  through the, you know, stealing their cattle and, you know, enslaving them and taking them off to work on agricultural farms in Mesopotamia. Like, they need to know this. And if you provide that context of stability, the economic growth, the demographic growth will return. And Diocletian created that kind of, that context.

• 1:21:23Lex Fridman?

  So that takes us to Constantine. But first, a quick bathroom break, if I can.

• 1:21:28Speaker 01

  Sure.

• 1:21:29Lex Fridman?

  Quick 10 second thank you to our sponsors. Check them out in the description. It really is the best way to support this podcast. Go to lexroman.com/sponsors. And now, dear friends, back to our conversation about the Eastern Roman Empire. All right, we're back. And let's talk about Constantine and Constantinople. Let's go to the rise of the East Roman Empire. Who was Constantine? Tell me about his rise to power and the founding of Constantinople in 330 AD.

• 1:22:01Speaker 01

  Sure. So Constantine was the son of one of Diocletian's colleagues. So he comes from within the system. And the system was actually designed to be non-hereditary. In other words, the senior emperors would retire, the junior ones would move up to the senior position, and then they would recruit two new ones. And they tried to skip the dynastics element. So it would be kind of, let's just say, kind of meritocratic, not whose son, you know, you were. Constantine was a son, he was passed over, but the armies liked him. He was actually quite competent. And so there's a series of civil wars among all of these successors of Diocletian, and Constantine emerges as the winner. There are periods

• 1:22:44Speaker 01

  when there are quite a few of them, like six at a time, but they gradually window down to one. So, yeah, it's as long as you have the quarterfinals, semifinals, the final war, and Constantine emerges in 324 as the sole ruler of the entire Roman Empire. So that's who he is. He's definitely an insider, very, very competent general at civil war. And he gradually moves eastward.

• 1:23:13Speaker 01

  So as he's conquering his rivals, who are often at times his father-in-law's or his brother-in-law's, but because these people are all intermarry and they have alliances and they fall out. It's one of those kinds of situations. He moves eastward and by the time he defeats his last rival, this emperor called Licinius, in 324, he's in the east. And Licinius had his headquarters, or one of his headquarters, at this town called Visandio. Visandio is a city right where Constantinople was founded. And it is at exactly the point where Europe meets Asia. So on the Bosphorus. And it's a very strategic location. It always had been, right? So whoever controls the Straits of the Bosphorus,

• 1:23:57Speaker 01

  yeah, we don't need to explain how important that is. And Constantine decides to create a city named after himself, Constantinople, on that spot, Visandio. So Visandio essentially ceases to exist as a city and is replaced by Constantinople, AKA New Rome. So it's pretty clear that right from the beginning, Constantine intended this to be a kind of branch office of Rome in the east, a kind of copy and paste of Rome in the east. And it's a plan that his successors continued, right? Now, there are a number of other cities in this, let's say, in the generation or two before this,

• 1:24:40Speaker 01

  that were also treated as sort of quasi-Roms. Basically, there was this historian in the third century who said, "Well, wherever the emperor is, that's Rome." Because emperors are now itinerant. They're no longer staying at Rome. They're mostly on the frontier. And Constantine is one of these frontier emperors. They will sometimes visit Rome, maybe once or twice, maybe once a decade, you know, something like this. So Rome becomes something that can be sort of copied and pasted in other parts of the empire. And a bunch of other cities get called, you know, a new Rome, an other Rome, an alternative Rome, my Rome. And Constantinople is the last and most successful of those.

• 1:25:21Lex Fridman?

  So maybe can you speak geographically, the importance of Constantinople? It's an interesting place because it... When you're talking about a land so large as the West and the East, with enemies, with threats from all kinds of different directions, the location where the emperor sits is important.

• 1:25:40Speaker 01

  Very. So, look at Rome. Right? So, it's right in the middle of Italy, right in the middle of the Mediterranean. Very safe location, in a way, but it's very far from the frontiers. And this is a period when emperors need to be with the armies. Right? They're not senatorial emperors who are sitting in Rome having meetings with senators. They are military emperors who are marching along the frontiers, mostly with generals rather than civilian administration. So, they're doing their job. Like, this is the hard work. They're slogging through the mud of winter campaigns, right? They're not just sitting in a palace enjoying themselves when they could.

• 1:26:22Speaker 01

  But Rome just becomes inconvenient because of that. And if you look at Constantinople, it is kind of halfway between the Danube frontier and the Euphrates frontier. So, if you want to prioritize the East or treat it as an equal part of the Roman Empire, as these emperors all did. In fact, almost all emperors who had a choice about whether they would stay in the East or stay in the West, chose the East. There's only one who chooses the West, and that's Valentinian later in the 4th century. All the others understand that the East is where it's at. And Constantinople is right between the Danube and the Euphrates. These are the two major frontiers. And so, it allows emperors to move between the two.

• 1:27:06Speaker 01

  And also, look at its location, north, south, east, west, right? So, north, south, it is the node between the Black Sea and the Mediterranean, right? And east, west, it's precisely where Europe meets Asia, right? And because there's a break there, so there's a Bosporus, the Sea of Marmara, the Hellespont, the Roman Empire during the civil wars, it would tend to break there. And you would have one emperor on one side in Asia, and you'd have another emperor on the other side. And this just kept happening. And Constantinople ultimately functions as a kind of clamp that unifies this whole

• 1:27:45Speaker 01

  area. So basically, the Balkans and Asia Minor and Syria as a kind of unit, right? And, you know, what is a new Rome? A new Rome is, among other things, a new Senate, right? And Constantine and his successors recruit this new Senate for the new Rome. So we're talking about maybe 2,500, 3,000 men, you know, at its peak. And these are all recruited from all of these areas. You know, some come from Rome, but others come from the Aegean region, from Asia Minor, Eastern Mediterranean. So these are the wealthiest

• 1:28:26Speaker 01

  people, usually most well-connected elites from the whole Eastern Mediterranean. And they come together and form a new purpose, common purpose, in Constantinople. And the empire never breaks there again, right? So it holds together this part of the world. The breaking point now, interestingly, moves to the Adriatic, right? So when in 395, we talked about East and West kind of splitting, it breaks at the Adriatic because Constantinople is now holding that whole Eastern world together. Because all of these elites, they now, they're invested in it. They're literally investing in it. They have to invest in it in order to be senators in Constantinople. So that's kind of one of the functions that it performs,

• 1:29:06Speaker 01

  a strategic function, a political function. There's also a cultural one, but you can talk about that, too. But that's what you see there on that map, the northwest, east, south.

• 1:29:17Lex Fridman?

  So just to linger on it. So you do a podcast, Byzantium and Friends, but you're also a guest on the podcast. And I should mention you being a guest multiple times on the excellent, The History of Byzantium podcast hosted by Robin Pearson. I highly recommend people listen to it, to all of your appearances. You have a lot of really fascinating ones. But the reason I bring all of that up is one of the episodes, you do the fun thing of selecting the top 10 emperors of Byzantium.

• 1:29:50Lex Fridman?

  And spoiler alert, everybody should go listen to the full list because you justify all the different options. But Constantine ends up in the number one spot. And so can you just add a little bit more depth why he would be in your number one spot now that we're talking about him?

• 1:30:10Speaker 01

  Yes, it's not because I sort of like him as a person, right? As you said, he was pretty murderous.

• 1:30:16Lex Fridman?

  Yeah.

• 1:30:17Speaker 01

  Right, all those wars, so clearly ambitious, murderous, ruthless, basically.

• 1:30:23Lex Fridman?

  Can you actually speak to the murderous aspect? He seemed to have murdered a lot of people in his family.

• 1:30:29Speaker 01

  Yes, that's because what we call his family were also alliances of convenience that he made on the way to the top. And when those alliances or, you know, those, you know, those wives or those fathers-in-law were no longer convenient or turned against him, he had no hesitation in removing them. But he's also, you know, he gets a little extra bonus because he also murdered his own son, Crispus, who was apparently a very competent and popular kind of general, and we don't know why. He executes Crispus soon after defeating Licinius and then follows it up with the murder of his wife, not Crispus's mother, and we don't know why.

• 1:31:14Speaker 01

  The funny thing is that when emperors do this sort of thing, if there's any kind of remotely like a good reason, they'll blast it through all of the media, right? Like Crispus was rebelling against me or whatever. There's nothing. He doesn't even try to justify it, which means it must have been something unjustified. Like, I don't know, I can't process it.

• 1:31:34Lex Fridman?

  And also I read that there's historians of the time who just ignore that that happened.

• 1:31:40Speaker 01

  Yes. Well, sort of. So when Crispus is alive, it's all like praising Crispus as, oh, Constantine, you great emperor and your wonderful son who will whatever. And then Crispus is executed and he just disappears from the, like, they never talk about it.

• 1:31:55Lex Fridman?

  Yeah. Actually, as another side to a side, you, I think you mentioned.

• 1:32:02Lex Fridman?

  Whether it's on your podcast or elsewhere, if you had to have a beer with any of the emperors that you probably wouldn't. So it's not like some of the most impactful, some of the most influential and great emperors that we talk about, they might not be very pleasant people.

• 1:32:20Speaker 01

  Right. So let's set aside whether you'd like to have a beer with these people. The reason I put Constantine at the top of the list is because the decisions that he made were so consequential, just important and for the most part, not bad decisions. So I couldn't not put him at the top of the list. You know, creating Constantinople and converting to Christianity and setting the empire on a path to conversion, these are major, like world history level decisions, right? Now, not many emperors do that. In fact, Constantine is in like his own league when it comes to those kinds of decisions.

• 1:33:03Speaker 01

  My other criteria for top emperors were basically those who did the job well, right? Not making, you know, these kinds of earth, you know, shattering decisions or, you know, world history changing decisions, but just who performed the role competently with results that impacted the lives of their subjects for the better. So those are the other criteria that I used. It's difficult to juggle these different criteria, right? In order to create a systematic list. And by the way, historians generally don't do these kinds of things, but you said it's fun.

• 1:33:38Lex Fridman?

  It was fun.

• 1:33:39Speaker 01

  It is fun. And it allows you to talk about certain things that you might not otherwise do. So yeah, that's why Constantine was at the top.

• 1:33:46Lex Fridman?

  So you mentioned Christianity. That was one other big component of his rule. What was the role of Christianity in Constantine's life, in the lives of the citizens of the new Roman Empire?

• 1:34:00Speaker 01

  At this stage, Christianity doesn't yet have a role. It actually took the emperors. When the emperors took it on board, that is, they made it a part of the imperial system, then it began to acquire a role within this system. Previously, it had imagined itself as having its own history, like not necessarily part of the empire or affiliated with imperial power. But after Constantine, it does acquire a role.

• 1:34:27Lex Fridman?

  So it's actually, one way to ask that question was just fascinating because you said that there's like, there's Rome, and then there's like cultures, like, or traditions, like Christianity, or being Greek, that kind of thing.

• 1:34:43Speaker 01

  Yeah.

• 1:34:44Lex Fridman?

  So one of the ways to ask this question is, does Christianity triumph over Rome, or did Rome capture Christianity?

• 1:34:51Speaker 01

  Right, yes.

• 1:34:52Lex Fridman?

  Which is the mechanism?

• 1:34:56Speaker 01

  I would lean more toward the second. In other words, that the religion was co-opted by the imperial system. Now, there are many areas in which that's not the case and where the opposite happens. So I'm not going to be absolute about it. But I think it's very important to recognize that because Christianity generates this narrative of triumph, right? Which modern historians perpetuate, and it's framed in very particular ways. In other words, that Christianity triumphs over the ancient religions, right? So displacing Zeus and Apollo and all of that, and animal sacrifice is gone, and like, that's because Christianity triumphs. And that's a very narrow way of looking at it. In other words, you pick your enemy and then you can defeat that enemy, right?

• 1:35:39Speaker 01

  But if you look in the other direction, there's like the Roman imperial state, and you cannot say that Christianity either triumphed over it, or even tamed it, or anything, it actually became part of it. In many ways that, you know, determined its history for centuries and in fact, down to today. So this is very different, for example, from the history of Islam. So Islam comes into existence without a pre-existing state to receive it and take it on board. It creates its own state, right? So the Muslim armies, they conquer this empire and then they have to sort of govern it. They think according to whatever Islamic principles, the Quran doesn't say anything about running an empire.

• 1:36:22Speaker 01

  So that creates a completely different society, right? Where Islam is really a primary kind of identity and drives a lot of developments. But Christianity comes into existence within a very well-developed society and political system. Now, here's the thing. We don't know exactly how many Christians existed in the time of Constantine. We speculate maybe 10% of the empire. That might be very high, right? But even if it's 10%, it's not a lot. And these are not elites, for the most part. Maybe middle, loosely called middle class, a few elites, a few slaves, like this kind of thing, mostly urban.

• 1:37:04Speaker 01

  And keep in mind, most of the population is rural, right? So pockets of concentrated Christian groups in cities. That's what we're talking about. Not terribly politically powerful.

• 1:37:16Lex Fridman?

  So Constantine's conversion to Christianity and moving the empire towards Christianity is not something where it's a gigantic majority of the people, or it's a political convenience because it's the elites. It's something else. I mean, pretty revolutionary decision, I would say.

• 1:37:31Speaker 01

  Exactly. Now, there used to be theories that Constantine did this for pragmatic cynical reasons, that he wasn't a true Christian or anything, but there was some kind of political gain to be had here. But I have never read a convincing account of what exactly that political gain is. We now know that there are fewer Christians. They were not that influential. You can make an argument that bishops are a convenient social influencers, you might say. You can use those. They're not a threat to your position, right? So bishop is not going to try to take the throne. So they're not dangerous political operatives in that way. But they do have some influence over sectors of society, and so that might be a... Okay, I see that, but I don't quite see the

• 1:38:15Speaker 01

  argument for like going full Christian just to get the support of some bishops, who actually pretty quickly turned out to be, some of them, more trouble than they're worth. Anyway, so I have not yet seen a convincing, like, political argument for Constantine's decision, which means that you then fall back on a personal explanation that he did this because he was a believing Christian, right? And, and he came out, you know, in support of the religion that he held. And that's kind of where most scholars are today, though I gotta tell you, historians are very uncomfortable about personal choice, like, explaining history in terms of these kinds of personal choices. Because Constantine's conversion is like, it's massive. It, it opens the door,

• 1:39:00Speaker 01

  it incentivizes so many people to also convert. Because Romans will generally do what their, you know, rulers will tell them. If we've mentioned Hadrian a few times, Hadrian's had this lover, Antinos, Greek boy from Bithynia, who died in an accident in Egypt, whatever. And Hadrian said, basically, that Antinos should be regarded as a god throughout the empire. And he was. We have like more statues and busts of Antinos from all of these temples all over the empire than I think of anyone else except Hadrian. So yeah, if the emperor says, like, this is a person is a god now, you know, put statues of him everywhere, they will. And when Constantine comes out in favor of Christianity, yeah, suddenly people

• 1:39:42Speaker 01

  discover that, oh, this is an interesting, right? It's got the support of the emperor.

• 1:39:46Lex Fridman?

  So one of the things here, going to the perplexity, Constantine's conversion to Christianity is usually dated to 312 AD, linked to a visionary experience before the Battle of the Melvian Bridge. Do you believe that vision, that he had this religious experience before the Battle of the Melvian Bridge? Here it says, "But historians debate both its nature and its sincerity." Do you believe the sincerity of that?

• 1:40:13Speaker 01

  Before we even get to the sincerity, it's the problem of the sources. This is reported by authors writing later, in the aftermath of a victory, when the emperor, like... One of them had a dinner conversation with the emperor a few decades later. And he said, well, let me tell you about the Milvian Bridge. And it's like, OK, I'm not going to believe that. I'm not going to take that at face value, rather. It's a much more complicated. This is how the emperor wants things to be remembered. That's different. Also, Constantine tended to have a lot of religious visions. He had had religious visions of Apollo before Christ. And we have sources that talk about that, too, that he went to this temple in Gaul, and Apollo appeared to him in the form of light. OK, Constantine has a religious vision. Every time, he kind of wants to shift policies.

• 1:40:55Speaker 01

  And, and his like profile, like when he wanted to break away from his other emperors, who used to go for the, like, they went for this kind of Jupiter Hercules model, and he shifted to an Apollo model. This is branding. This is emperors doing branding.

• 1:41:08Lex Fridman?

  So we should say that, as you've described, Constantine is a pragmatist. He's very pragmatic. But you're saying it's fair to believe, based on the evidence, that he actually converged towards being a Christian believer?

• 1:41:25Speaker 01

  Yeah, it's very possible, in fact plausible, that he thought the Christian God had helped him in battle. And, you know, for someone like him, that's as good a reason as any to support that God.

• 1:41:37Lex Fridman?

  But he was not like a hardcore Christian all the way through. He was a kind of a spiritual, religious kind of person. He thought about idea, religions more generally, and just converged towards Christianity as a good religion. He also had ideas about what a good religion is and what a bad religion is, that kind of stuff. So he's thinking in this space.

• 1:42:01Speaker 01

  He's tending not to be too explicit, depending on the audience. So Constantine remains a pragmatist in the sense that he doesn't want to alienate too many of his subjects, right?

• 1:42:13Lex Fridman?

  Fair.

• 1:42:15Speaker 01

  And so he's sometimes a bit coy or elusive about what he's getting at. When he's talking to Christians, he will talk about Christ. He will mention Christ. When he's talking to everybody else in like a general law, he'll just refer to good religion. And it's like, you, like, maybe you know what I mean, right? But, but he's not going to like, you know, come to Jesus.

• 1:42:36Lex Fridman?

  Yeah.

• 1:42:37Speaker 01

  So. Even at the time when he's like, supporting the church, like, basically institutionalizing the church as an part of the imperial system, but he's also putting up statues of himself that look like Apollo in Constantinople, right? So, the focal point of Constantine's Constantinople is the form of Constantine, and in the middle is this very tall column, and it has a colossal statue of Constantine on top, gilded, enormous thing. I don't know, like, eight meters tall or whatever. But it's a repurposed Apollo. It's even, like, visibly so. It's naked. It has the rays coming out of the head, right? And everybody knew it was an Apollo.

• 1:43:18Speaker 01

  So that's Constantine in the guise of his old patron god Apollo. Still, but he's still Christian Constantine. So he's sending all of these different messages.

• 1:43:28Lex Fridman?

  I mean, he likes being the godlike figure. I mean, that whole statue is just like, I am the god.

• 1:43:34Speaker 01

  Yeah, it's assimilating yourself to, yeah, yeah, yeah.

• 1:43:37Lex Fridman?

  And I mean, a lot of the Romans, is it fair to say, kind of saw the emperor a little bit now, like?

• 1:43:42Speaker 01

  Oh, yeah. They called him divine, and, yeah. There's not a hard theology there, right? Like, if you pressed them on the actual theology, they wouldn't, they wouldn't say the emperor is a god. No. This is mushy. This gets very, very mushy.

• 1:43:54Lex Fridman?

  But I mean, a lot of the Christians have a kind of humility before God.

• 1:44:00Speaker 01

  Yeah.

• 1:44:01Lex Fridman?

  I think when you have an emperor that's godlike, it gets a little weird.

• 1:44:05Speaker 01

  Yes.

• 1:44:06Lex Fridman?

  In the way you talk about God.

• 1:44:08Speaker 01

  It depends on the context. Like, there are contexts in which you are an emperor and you're proclaiming your majesty. And then there are more personal contexts where you might be more humble because, I don't know, you're being baptized or something. Like, those are different contexts.

• 1:44:22Lex Fridman?

  So can you speak to the whole process of the conversion to Christianity, of the propagation of Christianity throughout the empire and Constantine's role in that?

• 1:44:31Speaker 01

  Constantine, or his successors as well, because this was a gradual process. And it takes a very long time. So let's, let's put it into perspective. We probably can't talk about a majority Christian society until maybe the fifth century or early fifth, mid-fifth. We don't have data, obviously. And we can't talk about like a solidly Christian society until early sixth century. And by solidly, I mean maybe where the non-Christians are 10, 15%, right? So that's a long time. That's like five centuries after Jesus. That's half a millennium.

• 1:45:12Speaker 01

  So we're talking about a half a millennial process here. It's, it's very long.

• 1:45:18Lex Fridman?

  But it's only a couple of centuries after Constantine.

• 1:45:21Speaker 01

  Yes.

• 1:45:22Lex Fridman?

  So it takes about two centuries to really make the Roman Empire Christian.

• 1:45:27Speaker 01

  Yes. So very slow conversion, maybe, maybe up to 10% tops under Constantine. Then obviously, larger and larger groups join the church, even if only nominally, right? And until you get to the sixth century, when you're clearly talking about, you know, mostly or overwhelmingly Christian society. A lot of this is just done through incentives and disincentives, right? So bishops are given funds with which to distribute like charity and help to communities in distress. They have lists of widows and whatever they support. Land is given to the church by the emperors or in wills so that they can engage in this kind of social policy.

• 1:46:12Speaker 01

  And then there are disincentives. So emperors pass laws that increasingly restrict the exercise of traditional religion. Like you can't perform animal sacrifices. Then you can't start doing these, like tying ribbons to make wishes or like all of these things, like going out to sacred trees and doing this or that. Because they say, oh, this is kind of nefarious business or like magic or whatever it is. And then they just gradually start outlawing it more and more, putting restrictions on like, if you're not a Christian, you can't hold these high offices or you can't, you know, there's problems with your wills. So they gradually do it like that. And this is how you, yeah, this is, and it works.

• 1:46:51Speaker 01

  It works.

• 1:46:51Lex Fridman?

  What explains the success of Christianity after Constantine? Why, why, why was it as a technology so successful at spreading throughout the empire?

• 1:47:02Speaker 01

  Christianity developed in a number of ways. So it acquired a certain number of forms that were capable of appealing to different constituencies. In other words, there was an intellectual side to it. The sort of theology, the almost quasi philosophical or engagement with philosophical schools that could draw in, let's say, intellectuals. There is a public ceremony and ritual aspect where you can organize communities and cities to have processions or like have all these festivals that take the place of the ancient ones.

• 1:47:43Speaker 01

  You have a kind of, it's not secretive, but it's kind of this initiatory aspect where this is baptism and you, you learn a sort of creed and you're initiated into the religion with the prospect of a personal afterlife, right? And that appeals to other kinds of people. There's also ways in which it, it integrated itself into the court and the language of power, also in the army, right? Soldiers now swear an oath to the Trinity, right? So it takes all of these different forms that enable it to position itself, you know, here and there and, you know, in the streets, in the court, in the armies, in the churches,

• 1:48:28Speaker 01

  in the, in texts, in books. And so it has this kind of manifold diversity, right? That makes it very adaptable.

• 1:48:37Lex Fridman?

  So one of the things you mentioned that Constantine did not anticipate, did not realize that Christianity creates divisions between various groups.

• 1:48:46Speaker 01

  So in part, this is, happens when you have religions that make exclusive claims, right? Like my beliefs are true and yours are by definition false, not, not just wrong, but false and even kind of evil, like maybe Satan put them in your mind to lead you astray, right? And this is inherently divisive, like it is. So there's this paradox where Christianity, in contrast to say, the ancient religions, is both far more polarizing.

• 1:49:19Speaker 01

  But also far more powerful as a unifying force at the same time, right? So ancient religions tended not to produce this kind of conflict or identities, right? Or wars or these kinds of things. And they could, under certain circumstances, but for the most part, they were not drivers of history in this kind of way. But when you have exclusive claims, then suddenly these very communities of that are consolidated and have this very strong identity. But you also alienate other groups that you then are in conflict with. So this is why I, for one, can't come down on whether Christianity is more of a unifying

• 1:50:02Speaker 01

  force or a divisive force in the history of the Eastern Empire, because it's both.

• 1:50:06Lex Fridman?

  And also trying to figure out whether the unifying or the divisive aspects are a feature or a bug. Maybe some of the divisive elements is a way for society internally to try to, much like the civil wars, to try to figure itself out. So sometimes tension and conflict is a good mechanism for figuring out what do the people want?

• 1:50:29Speaker 01

  Or what's the truth?

• 1:50:31Lex Fridman?

  Or what's the truth?

• 1:50:32Speaker 01

  Yeah. So the story that it likes to tell itself is that there's this one original truth and the hardcore of true believers is defending that truth at every moment against all of these evil heretics who are coming in and trying to corrupt it. In reality, what happens is that this truth is something that's evolving in the course of the controversies. And often, they don't know that they believed that until in retrospect, once they've had the fight and the winner has this position, oh, now that turns out to have been the position we always held, right? And this happens again and again and again. A lot of the time, these Christian theologians who get into so much trouble and get branded

• 1:51:15Speaker 01

  as heretics and sometimes get sent into exile, they didn't mean any harm. They often just were stating what they thought everybody believed. And then when they blurted out, someone is often, Alexandria is like, what? That's heresy. And then now you're in trouble. Now you're getting into this fight and you might win, you might lose. But a lot of them were kind of well-intentioned in that way, or they had no intention of starting a fight. But there's always someone who wants to start a fight.

• 1:51:42Lex Fridman?

  Yeah, I mean, sometimes the fights are extremely intense over things that I could see on the surface or like iconography. It's like, it seems like a very subtle debate, like almost academic. And then a large number of people don't see it as academic. They, they do see it like the devil put ideas in your head that are completely wrong. And it's fascinating how that kind of division can emerge. I mean, I, the impossible question, and I apologize for asking it, but maybe just worthwhile to, to, to try to think about it is on the grand scale of centuries of

• 1:52:21Lex Fridman?

  the East Roman Empire, is religion a constructive or a destructive force for the empire? Did it help it flourish? Or did it hold it back?

• 1:52:34Speaker 01

  This society identified itself increasingly with what it saw as orthodoxy. Orthodoxy just means correct belief. I mean, like every religion ultimately thinks it's orthodox, right? That's, but that's the conventional name, right? Orthodoxy today might be called Greek orthodoxy. And I mean, it's such an essential part of the culture. It really is. I, I can't think of the two of them. I mean, I try to because as a historian, I have to test the, the models, you know, and try to see these things as independent of each other. But ultimately, it's very difficult to disentangle them. And I would say that to the degree that this is a successful society

• 1:53:17Speaker 01

  historically, that its religion definitely contributed to that and played a role in it. Not without cost, right? There are, it mattered to them. They valued it. But things that matter to you have a cost. And, and they, they paid that price. They were willing to pay that price for it. For example, at the very end, they had to choose between Catholicism, Western rule, where they essentially have to compromise on their faith, or rule by Muslims, the Turks, where they would not have to compromise their faith. And some of them were explicit that they were preferring option B, because the Turks will at least respect our identity.

• 1:54:01Speaker 01

  Like, that's a cost.

• 1:54:03Lex Fridman?

  Yeah, but there's other layers like taxation and the functions of government that are connected to religion, to the degree it interacts with the tax system. But it feels like that's the engine of the society and religion is more like the cultural layer.

• 1:54:20Speaker 01

  Yeah, so this is why I said that I try in, in, in thinking of the models that we use to understand this society, not to assume that religion is everywhere and for everything. Now, I have colleagues who do that and I would disagree with them about this, but you're exactly right. There are elements of this society that I like to see as their own thing, like the Roman identity, for example. It's not the same as orthodoxy, but also the operations of the state. Those are very pragmatic things and you see them intersect with religion largely in areas of terminology or the vocabulary that they use or, you know, like at the top,

• 1:55:04Speaker 01

  but not at their actual functioning. So in my field, I'm a historian who's tried to promote other aspects of the culture as having the kind of integrity of their own and not to subsume them all within orthodoxy.

• 1:55:21Lex Fridman?

  So, I mean, again, an impossible way of asking the same question. If you asked a Roman, a million Romans across a thousand years, are you a Roman or a Christian? What would be the answer for them?

• 1:55:39Speaker 01

  Both. Oh, absolutely.

• 1:55:40Lex Fridman?

  You don't get to say both. You're not allowed to do that.

• 1:55:42Speaker 01

  Why not? It's the true answer.

• 1:55:45Lex Fridman?

  Okay, so you're saying they're really tied together?

• 1:55:48Speaker 01

  Well, they overlap, but if you were to, and this might be a somewhat more subtle conversation than most of them would want to have, but if you were to say, is Roman and Christian the same thing to you? If they thought about it for a little while, they'd quickly be able to say no. Because there were, I mean, just logically, there were Christians who were not Romans, the Bulgarians, or the Rus', or whoever. There were lots of Christians who were not Roman, and they did not regard them as Roman just because they were Christian. Conversely, they knew perfectly well that there had been Romans who were not Christians. And they knew this how? Because in the churches, like, almost every week, they celebrated martyrs

• 1:56:33Speaker 01

  who had been killed by the Roman emperors in the past. And it was like, the performance of violence by Roman emperors against Christians was like something they remembered. They knew perfectly well. So those two things did not overlap perfectly. And there were some contexts in which you would be more Roman, and there were some contexts in which you would be more Christian. And you find characters who, and I love to do this. I find characters who, as some sources say, didn't pay too much attention to Christian things. There's just politicians. They were just doing their work. And then you find characters who devote themselves, they go all in on orthodoxy and monasticism. They just don't care about the Roman stuff at all.

• 1:57:17Speaker 01

  And that is, in fact, part of the reason why I like this society is because it has these kinds of options for people to choose. And there's another one. There's the Greek stuff, too. Because their language is Greek, their literature is Greek. And so there are people in this society who go all in on the Greek stuff, right? And I see this society as this kind of laboratory of these three elements coexisting in these fascinating combinations. Usually, it's combinations, right? But sometimes you will find people who are like, kind of try to be purists in one way or another. And it's the only society in history in which you can do this. Because it's the only society that's Roman and Christian and Greek. But in different ways, right?

• 1:57:59Lex Fridman?

  Yeah, unfortunately, I think it's tempting, but it's probably impossible to say, if we removed the taxation system, would Roman Empire be more or less successful? If we removed religion, would it be more or less successful? If we removed...

• 1:58:15Lex Fridman?

  Greek and kept it Latin all the way through to be more or less successful. It's probably impossible to do this kind of analysis because they're all so deeply integrated.

• 1:58:26Speaker 01

  And fundamentally, it also wouldn't be what it was. It would be something different.

• 1:58:32Lex Fridman?

  But there is a big temptation, and this is at the core of your work, and to understand why did the East Roman Empire last as long as it did?

• 1:58:40Speaker 01

  Yes.

• 1:58:41Lex Fridman?

  And why did the broader Roman Empire last as long as it did?

• 1:58:44Speaker 01

  Yeah.

• 1:58:45Lex Fridman?

  Because it is one of, if not the, most successful empires in terms of duration and stability in a very tense part of the world.

• 1:58:55Speaker 01

  That's actually like my next project. I'm starting to write a book, trying to explain, just kind of from a analytical standpoint, why?

• 1:59:04Lex Fridman?

  How did it last so long?

• 1:59:06Speaker 01

  Yeah.

• 1:59:06Lex Fridman?

  A lot of your work kind of hints at it.

• 1:59:08Speaker 01

  Yeah.

• 1:59:09Lex Fridman?

  Here and there, but you're trying to do it more systematic. So, and we'll keep hinting at it.

• 1:59:14Speaker 01

  Yes.

• 1:59:15Lex Fridman?

  But to put a bow tie on Constantinople, it went from a very low population of maybe 25,000 people to 500,000 people in just two centuries. So can you explain how that happened?

• 1:59:31Speaker 01

  Well, it didn't happen through just demographic growth and reproduction in the city itself. That rate of growth is impossible for an ancient city. So when I say 20,000, 25,000, that's possibly what the ancient city of Byzantium had when Constantine decided to found Constantinople. And it grew to a city of a half a million in two centuries. That can only have been done in one way, and that is emigration from the provinces. So people must have been moving there in, in large numbers, which is a movement that we can't see very clearly in the sources, but we have to infer it and then try to explain it.

• 2:00:13Speaker 01

  So also, there's another factor, which is that ancient cities we now know or suspect are what some historians call death traps. In other words, the density of disease is such that ancient cities probably are losing something like 1%, 2%, possibly 3% of their population per year. So just in order to stay with a stable population, they have to import people. Right? Now, they're not like 17th century London. They're not that bad.

• 2:00:46Lex Fridman?

  Does diseases and plagues seem to be prevalent?

• 2:00:49Speaker 01

  Oh, yeah. Now, you know, Roman cities have some corrections for these sorts of things, like the way they distribute the water through the city. Anyway, they weren't as bad as they could have been, but there's that. So not only to keep the population steady, but to expand it so dramatically means that a lot of people are coming in from the provinces, mostly the Greek-speaking provinces. So, you know, Greece, Asia Minor, and some of the major cities in the east that are Greek-speaking. And I started wondering, like, well, how did this happen? Like, who are these people, for one thing? And then I did some simple calculations. So I mentioned earlier that we have something like 2,500 senators who are required initially

• 2:01:34Speaker 01

  to reside in Constantinople. Well, senators don't live in bachelor pens. Senators have manners, they have household staff, right? In Rome at the time, there's a calculation that a notorial household was something like 100 people, right? Just servants, slaves, dancing girls, cooks, barbers, whatever, right? So let's assume sort of conservatively that in Constantinople, it's only 30 people, which might be low, right? So if you do the math, you're starting to get something like, I mean, closer to 100,000 people, right? And that's just by bringing in senators, right? They come with people.

• 2:02:18Speaker 01

  So I think this was the nucleus of the population. Now, then Constantine also makes provision for possibly up to like 200,000 people to receive the grain dough, the bread.

• 2:02:35Speaker 01

  So that would have incentivized even more people to travel there because there are-

• 2:02:39Lex Fridman?

  So you get free bread?

• 2:02:41Speaker 01

  Yes. And you can't live on that alone, but it is, it's something.

• 2:02:44Lex Fridman?

  Incentive.

• 2:02:45Speaker 01

  Yeah.

• 2:02:45Lex Fridman?

  Is it true that he diverted resources from Rome to Constantinople?

• 2:02:49Speaker 01

  Absolutely. Oh, yeah. That grain, that's coming from Egypt. So New Rome is literally stealing food from the mouth of Old Rome.

• 2:02:58Lex Fridman?

  Yeah.

• 2:02:58Speaker 01

  Now, Old Rome doesn't starve because they divert other, like from North Africa and Sicily, you can feed Rome, right?

• 2:03:04Lex Fridman?

  But it sends a strong signal to the people living in Old Rome that long-term should probably move.

• 2:03:11Speaker 01

  Some people do move. So we know of some senators who moved from Rome.

• 2:03:16Speaker 01

  It sends a signal about the priorities of the state, like they're investing much more in the East, and that the East would be regarded as a equal, parallel Roman, you know, world. Yeah.

• 2:03:26Lex Fridman?

  As we talk about diverting resources, slowly, the West declines and collapses in 476 A.D. So Visigoths sack Rome in 410 A.D. And in 476 A.D., the last Western emperors deposed, marking the end of the Western Roman Empire. High-level question, what is the reason for that decline and the collapse of the Western Roman Empire? So nonstop civil wars, as we've talked about, weak emperors, there's a economic money crisis,

• 2:04:07Lex Fridman?

  so shrinking tax base, rising army costs, there was a loss of key provinces, especially in North Africa, reliance on contracted barbarian troops as they immigrated more and more into the Western Roman Empire, cascading invasions, migrations amplified by Han pressure, and then the east-west split. The richer East survives, the West can't stabilize under that split.

• 2:04:41Speaker 01

  The crux of the matter is that barbarian armies, so armies from outside the empire, put increasing pressure on it during the 5th century. And for whatever reason, when the Roman state failed to sort of suppress one of them and say, settled them here, or allowed them to have here, or couldn't stop them, and they took over a province like the Vandals did in North Africa. This created this kind of vicious cycle because then the Roman state lost access to the resources from those provinces. That is, the taxes. And without those resources, they couldn't, you know, maintain, mobilize, pay for their armies. Then they had fewer armies to handle the next wave of barbarians that came in.

• 2:05:26Speaker 01

  The previous barbarians who settled kind of declared their kind of independence. They also could not be put down. And so this created a vicious cycle that just continued in that way. It's not rocket science, actually. I mean, you can see it playing out. Now, who these groups are, where they came from, why did they cross? Those are different questions, right? But from the Roman standpoint, that's how it was experienced. These are armies that can defeat a Roman field army, right? In battle. And sometimes they do.

• 2:06:01Speaker 01

  And they then settle and take over territories. And then you lose the revenues. And so you can't recruit your own armies. And so, anyway, that's the kind of cycle. The East tried to help. Occasionally, they would send forces, but they were also subject to some of the same pressures. Because remember, the Goths cross the Danube for the first time in a major way in 376. Then you have the Battle of Adrianople a couple of years later, where like 1 1/2 field armies is just annihilated. And the Emperor Valens dies, and the Goths are just like kind of loose in the Balkans.

• 2:06:34Speaker 01

  And there was then a long war with them, four years. It results in a kind of truce where neither side wins. And the Romans for the first time accept the presence of this quasi-independent Gothic army in the territory of the empire. This is unprecedented, as I said. And it creates a lot of tensions and dysfunctions. Okay. So why does the East survive and the West does not, right? And so there are lots of reasons that we can give here. But one of them... Is a geography that we were talking about earlier. In other words, without a fleet, which they don't have, the Goths can't cross over

• 2:07:14Speaker 01

  from Thrace or the Western Balkans to Asia Minor and go plunder some of the more prosperous provinces. So they're stuck in the Balkans, they're gradually pushed kind of in toward the Western Balkans, which is like the worst part you, you know, at the time, like you want to be in. And eventually they just decide, well, you know, it's kind of nicer in Naples. And so they go to Italy, right? Just because there's just a lot more resources there for them. And that's one way that the East just kind of manages to, it doesn't do this deliberately, but it, the geography kind of pushes these invaders to the West.

• 2:07:54Lex Fridman?

  So that's one. So geography is some of it's sort of the luck of geography and

• 2:07:59Speaker 01

  Yeah.

• 2:07:59Lex Fridman?

  Both of the invaders and the geography of the empire.

• 2:08:02Speaker 01

  Yeah.

• 2:08:03Lex Fridman?

  But, you know, the, the East had a lot of invaders since.

• 2:08:08Speaker 01

  Yes.

• 2:08:09Lex Fridman?

  And was able to still barely at times

• 2:08:12Speaker 01

  Yes.

• 2:08:13Lex Fridman?

  Survive the invaders. So, and some of that could be luck, some of it could be about the nature of the invaders and the, the effectiveness of their military, all that kind of stuff.

• 2:08:23Speaker 01

  By the way, it worked in the other direction, too. So if you have like Persians or Arabs coming into Asia Minor from the East, they usually can't cross over into your Balkan provinces. So you can fall back on one side or the other side. They, if you fortified Constantinople so that it's an impregnable bunker, which it was, right? So you, you're holding your command center in Constantinople. You can alternate between your European or your Asian provinces, depending on where the trouble is. You can call in reinforcements from either side. So the East does have that kind of advantage. This is not the reason why it survives for as long as it does, though it is a reason. Also, they acquire flamethrowers at some point, which those help too.

• 2:09:04Lex Fridman?

  Yeah.

• 2:09:05Speaker 01

  Right? Ultimately, I think it's the decision made by local communities to stick with the Roman state. Like ultimately, like they're not going to actively side with invaders. And when the trouble passes, they restore community, ties with Constantinople immediately. Like this is their natural political home. And, and that's the question that I'm really trying to answer. Like, why does that happen?

• 2:09:30Lex Fridman?

  You know, we should say, just like we've articulated multiple times, that the Roman Empire survives.

• 2:09:37Lex Fridman?

  So it's not like the Roman Empire collapsed and then another Byzantine Empire was born.

• 2:09:42Speaker 01

  Yeah.

• 2:09:42Lex Fridman?

  Really, there is a shift that happens. And part of that shift is because of Constantine. Right? It's not just about where the capital is, but I'm sure that there is just a general move towards that direction. From the West to the East.

• 2:09:58Speaker 01

  Yeah.

• 2:09:58Lex Fridman?

  And that, in many ways, you know, weak emperors and the West, the weak leaders, the structure of government, all these kinds of elements put together. Maybe demographic shifts and declines that have to do with the fact that the center of the empire has moved.

• 2:10:17Speaker 01

  That's right.

• 2:10:18Lex Fridman?

  And so ultimately, it's not that the West Roman Empire collapsed. It's that the center of the Roman Empire shifted.

• 2:10:27Speaker 01

  Yes.

• 2:10:28Lex Fridman?

  And because of that, the historic West collapsed.

• 2:10:31Speaker 01

  It's quite striking. So for example, already by, like, in the 430s, Constantinople is basically codifying Roman law for the West. So Roman law in Latin is codified in Constantinople and then sent to the West as, oh, here's your law code. And this is in the 430s, so after the alleged division between the two, which, like I said, is kind of loose. It's not hard and fast. In the 6th century, it is the East that reconquers part of the West under Justinian. And not only that, he also recodifies Roman law on a much bigger scale. And then that law becomes Western law.

• 2:11:12Speaker 01

  So in a certain sense, Roman law as we know it comes from Constantinople. It doesn't come from ancient Rome. I mean, ultimately, it comes from ancient Rome, but we don't have those versions of it. We have the East Roman versions of it. It is East Rome that reconquers Rome. This is a funny inversion, you know, because Constantinople is situated in a province, Thrace, which always was sort of considered backwards. Right? In the time of like the early Caesars, if you were in Rome and you thought, you know, Thrace, it was like, ugh, it's like, you know, some sort of armpit of the Roman Empire or something, you know? But by Justinian times, complete inversion, like the capital of the Roman world, the heart of it,

• 2:11:52Speaker 01

  is there and Rome is this kind of backwater provincial city in Italy, you know, that you've just liberated from the Gost and it's kind of in ruins, there are wolves roaming the streets of the Forum. So this is a complete overhaul of the centers of power. It's turned inside out almost.

• 2:12:11Lex Fridman?

  And I think it's fair to say that the reason the East, part of the reason the East lasts as long as it did is the topic that we've mentioned, which is the structure of government. So can we just zoom out once again and explain the key ways that government functioned in the East Roman Empire? And how it evolved over the lifetime of the empire?

• 2:12:31Speaker 01

  Very broadly speaking, there's civilian and military. Right? And you might actually add the church. It's entirely plausible to treat the church as a kind of government institution at this time. But let's just stick with military and civilian. The military is pretty straightforward, would be recognizable to any student of military history. This is how you recruit, organize, equip, pay and lead soldiers. And the East Roman state tends to have a larger military, at least paper strength. Active is a different matter. Like, how many soldiers you take on a campaign is a different matter. But how many soldiers you maintain like in the provinces generally, right?

• 2:13:16Speaker 01

  It tends to be on the large side for a medieval society. Right? So it compares favorably to, say, the caliphate later on, which is a much more massive territorial entity. So the military is that. It can have anywhere between 100,000 at a minimum at a low point, up to maybe about 250,000 at a high point, depending on the period. It's a lot of people. It's a lot of men, factoring in their families. Right? These are also like part of the whole, you know, military economic.

• 2:13:57Speaker 01

  Complex, if you will.

• 2:13:58Lex Fridman?

  And they're career military. So like, this is their job.

• 2:14:01Speaker 01

  Yes.

• 2:14:02Lex Fridman?

  And is the military for most of the history of the East Roman Empire defensive military?

• 2:14:08Speaker 01

  Mostly, but not always.

• 2:14:11Lex Fridman?

  Yeah. And we'll talk about Justinian.

• 2:14:13Speaker 01

  Sure. And so then you have the civilian administration. Civilian administration does a number of things. Principally, it is to find the funds to pay for this army, which is the single largest expense on the state budget, right? And so in order to find those funds, it has to have census of the assets, and it has to be able to tax them. And there are lots of different ways of doing that. So the civilian administration has a number of tax bureaus, records, keeping this sort of thing, also a legal branch for resolving disputes with the imperial fisc. Okay. But the civilian administration does a number of other things too.

• 2:14:53Speaker 01

  For example, the whole legal regulation of the of the empire, the courts, judges, courts of appeal, or also issuing laws, keeping records, all of this. And those are the main bureaus that have to do with the subjects of the empire. The emperors obviously maintain bureaus that are for things like diplomacy, right, or running the palace staff, because the palace is a huge institution, right? With, and then there are a number of endowments that, you know, major churches, I guess Sophia, for example, has hundreds of staff, clergy to, you know, readers to whatever. And so they need to be paid. And so you need endowments.

• 2:15:38Speaker 01

  The imperial household, it has expenses, so it needs endowments, right? So there's a lot of land that's earmarked for these kinds of expenses that requires administration. So this multiplies, right? I mean, go on and on and on and on.

• 2:15:52Lex Fridman?

  And I'm sure the tax code is not a simple, flat tax. It's probably incredibly complicated. So it's just like in the United States. It feels like majority of the United States is basically lawyers and the IRS.

• 2:16:08Lex Fridman?

  That's maybe ninety, ninety-eight percent, I think, is lawyers.

• 2:16:11Speaker 01

  Lawyers.

• 2:16:12Lex Fridman?

  I'm not sure is scientific.

• 2:16:13Speaker 01

  I thought they shrunk the IRS down now to a size that it can't like actually do anything.

• 2:16:17Lex Fridman?

  They shrunk it down.

• 2:16:18Speaker 01

  I thought it was just.

• 2:16:19Lex Fridman?

  To just ninety percent.

• 2:16:20Speaker 01

  Ninety.

• 2:16:22Lex Fridman?

  No.

• 2:16:24Lex Fridman?

  I think there is something, this is another conversation about human nature and about the, the nature of governments. But there's, there's something about, like, I think it's impossible to have an IRS type organization that doesn't grow. I think maybe with good intentions, because you can't, you have to like, everybody always comes to you, well, I don't, here's my special case, I want my tax to be lower. And then you kind of add another line, all right, if you have purple hair.

• 2:16:59Speaker 01

  Right, right.

• 2:17:00Lex Fridman?

  The tax decrease. And so you keep adding, and then of course, the more you add,

• 2:17:06Lex Fridman?

  the more opaque the thing becomes, therefore corruption seeps in, or, you know, maybe not of, of like official corruption, but corruption light. And then either that tax code grows, and then all of a sudden you have these big institutions that then encourage corruption. And then there's a bureaucracy and there's a momentum, and this is just how humans are.

• 2:17:25Speaker 01

  Yes. So this happens in East Roman society too. I'll give you some examples. So

• 2:17:32Speaker 01

  there's not a tax code as such, but what you, the way it operates is through basically exemptions. So you petition for an exemption, you might be a monastery, you might be a wealthy land, you might be someone well connected to the court. You might be a struggling provincial village and you petition the emperor or some official and you say, hey, we know, we had bad season, or the barbarians came through and they took all of our, we can't pay the taxes, could, could we have an exemption? And emperors often are granting these exemptions for very specific things, like maybe for this year or for that tax or whatever. The problem is that the emperors are discovering every once in a while that their officials are granting these exemptions sort of on their own. So every once in a while, the emperors have to like clear house

• 2:18:17Speaker 01

  and they have to like, like cancel all of these exemptions and start the whole process again. But later on, when, once we start to have documentation, like maybe in the 11th century, we see that every little, well, not every, but we have all these monasteries, these little villages, these high officials, and they all have these documents that gives them exemption from this or that or the other thing. And it gets so complicated and that's how it works.

• 2:18:43Lex Fridman?

  But it is the engine of society that makes the whole thing worse because you have to fund, I mean, there's infrastructure projects, but you have to fund the army and the army is necessary to defend against all the military incursions.

• 2:18:55Speaker 01

  Yeah, yeah, yeah.

• 2:18:56Lex Fridman?

  A good fraction of the bureaucracy seemed to have been eunuchs, which are castrated men. Can you explain why this was a prominent thing?

• 2:19:05Speaker 01

  The eunuchs are part of the household staff of the emperor. So that would be like, what would it be? The, the west wing of the White House or something like this? So they are the people who handle the imperial person, the bedchamber, the organization of palace life, things like banquets, you know, these kinds of things, the wardrobe. And why are they important? So for, for starters, if you're like physically with the emperor all day, right, like you're handling the meetings, you're right? People can come to you and say, hey, I need you to put in a good word for whatever. Right? So they can get things done. So you bribe them, they get things done. So they're very useful in this way.

• 2:19:49Speaker 01

  They're also kind of hated for that reason. Right? But they're also kind of there to be hated. In other words, they soak up a lot of the frustration that people sometimes feel when they're not getting, you know, their, what they want from the court. Okay, that's one thing. Here's the other thing that's more interesting. How do you, as an emperor, make sure that your bureaucracy doesn't displace you? Like, if the bureaucracy is handling all the matters of running the empire, what do we need you for? Right? Like, the bureaucracy can develop rules of its own for solving all the problems, for dealing with petitions and exemptions and whatever. Like, they can do it. So where's your power exactly?

• 2:20:32Speaker 01

  So what the emperors did not want is to be displaced or overshadowed by these kinds of more impersonal institutions. And so they would often set up, like, parallel tracts of power. This could be a bit confusing. So eunuchs were perfect for this reason because often their origin was from outside the empire, or they were former slaves. They weren't connected to, like, networks of powerful families. So you knew that they would generally be loyal to you because they depended entirely on you, the emperor, for their position and their power. And what you would sometimes do is you'd say, "Okay, I'm putting you in charge of, like, this army." Literally, like, putting you in charge of an army, just so you can counterbalance

• 2:21:15Speaker 01

  the, the kind of networks of established generals. And you'll have, like, "No, a eunuch from my wardrobe. You know, I'm putting him in charge." And so this kind of shook things up a little bit, so that people who were part of a system or a network could never fully count that that could get them all the power that they wanted. Now they have to answer to this eunuch from the wardrobe who's, like, outside of their system. And sometimes these eunuchs were extremely competent, like Narcissus Justinian's general who defeated the Goss in Italy in this massive battle. Like, this guy was a total hard ass. He was this little old man. He was, he was very old, he was tiny, and he was a eunuch. And the Goss laughed at him, but he had the last laugh, right?

• 2:21:57Lex Fridman?

  Is there some component to them being eunuchs so they can't propagate the bloodline?

• 2:22:02Speaker 01

  Yeah, they can't have their own family, so they can't be, like, looking out for their own offspring. They're kind of isolated individuals who depend entirely on your favor.

• 2:22:14Lex Fridman?

  Is it known whether the castration is almost always by force?

• 2:22:19Speaker 01

  There are eunuchs in society generally. They're often bishops, they're appointed patriarch of Constantinople sometimes. They're, they're in all kinds of positions. Many of them are children who are enslaved and castrated against their will.

• 2:22:34Speaker 01

  Sometimes, however, they are castrated very much according to the will of their families. In some parts of, like, in, in Caucasia, there were some regions that were famous for producing eunuchs. Also, in Persia and so forth. But also, we are pretty sure that this happened within the empire. Because there were some families that like really wanted to place a eunuch at the court. So from Patagonia, there were a number of, this is in northern Asia Minor. And so they would, it was almost like a family strategy.

• 2:23:08Lex Fridman?

  I mean, it's fascinating. It's fascinating that they had so, so much representation in the inner circles of the emperor and therefore had real influence.

• 2:23:21Speaker 01

  Oh, yeah. But this was the case always, even in Rome, like in the Julio Claudians, under, you know, the first Caesars. There are all these powerful eunuchs and the senatorial class always hates them. I mean, it's just, it's the same dynamic.

• 2:23:35Lex Fridman?

  One of the interesting things you've said, as an aside in one of the many podcasts I listened with you is, you said that there were no isolated people.

• 2:23:46Lex Fridman?

  You know, people that are disconnected from the empire.

• 2:23:51Lex Fridman?

  Maybe who, for example, don't know about the taxes or just don't feel integrated into the system. I mean, that's really interesting to me that there's so much connectivity, there's so much cohesion.

• 2:24:03Speaker 01

  Yeah.

• 2:24:04Lex Fridman?

  As an entire peoples.

• 2:24:05Speaker 01

  These people do not exist, these isolated peasants. This is a myth that I, one day I'm going to write a chapter about this. Because it's this idea that you occasionally encounter, actually quite often in the scholarship, that there are these rural communities out there somewhere that don't know what's going on in Constantinople. They might not even know who the emperor is. They're cut off. Maybe a tax official will show up every once in a while, maybe not. And they just live their lives on their own, unaffected by the, say, state. Because the medieval state, we suspect, is, you know, always powerless and can't, you know, affect people's lives.

• 2:24:48Speaker 01

  There's no proof for these communities at all. At most, you might try to find some like actual hermits, like actual Christian aesthetic hermits who try to go out and find this situation. And sometimes they're described in the text as like so and so went so far out into the mountains that not even the tax census people showed up there, which tells you how they think about what it means to be isolated, right? So this is a state in which every piece of arable land has been censused for centuries. It's not like you can hide a village, right? And the taxation process is not like they visit once a year, give us some coin and we'll leave.

• 2:25:32Speaker 01

  It's actually more like three times a year. And the taxes is not just coin and maybe a payment in kind or something, but it's a whole bunch of things like services and recruits and you're right. And once you start adding all of these things up, it creates a very dense institutional matrix in which all communities are enmeshed. They can't get out of it. Also, they have a church, don't they? And if they have a church, they have the calendar. And of course, they have the calendar because so like, how do they organize time and space and boundaries and all of these things? No, this is all state institution. How do they pay for anything? They have coins. Coins are everywhere.

• 2:26:15Speaker 01

  So I think that these institutions structured the way that everyone, even in village communities, even in the most isolated ones supposedly, how they thought about things like time and space and value and relations and power and kinship and so forth.

• 2:26:32Lex Fridman?

  So what you're saying is taxation is the thing that brings the empire together.

• 2:26:37Speaker 01

  It is principally, yes.

• 2:26:39Lex Fridman?

  I mean, it's true, right? This is like, this is how you know.

• 2:26:43Speaker 01

  Yeah, but on top of that is layered things like the economy, coins, right? But also, there's a church.

• 2:26:49Lex Fridman?

  Yeah, and church is important, just like you said, yeah. And there's churches throughout the empire.

• 2:26:54Speaker 01

  Yes, and they have sermons and. And they pray for the emperor after this service. No, there are no isolated communities.

• 2:27:02Lex Fridman?

  So one of the things I briefly mentioned, just it would be nice to elaborate on is this term of monarchical republic. So we've been throwing around words like kingdom and republic and empire and monarchy. So what is the actual, what's a good applicable term to what this thing is?

• 2:27:27Speaker 01

  Yes.

• 2:27:27Lex Fridman?

  The East Roman Empire.

• 2:27:28Speaker 01

  That's an excellent question, and I'm glad you flagged that because we call it conventionally Byzantine Empire, and it's neither of those things, really. We talked about Byzantine.

• 2:27:38Lex Fridman?

  Yeah.

• 2:27:39Speaker 01

  Now, empire is a bit of a problem because, first of all, there's no term in Greek, in the Greek that they use at this period, that corresponds to our notion of empire. It's not part of the official terms. It's not even, they didn't even have a term for it. You could have, there's some terms that might mean something like state, arche maybe, or katos. But for the most part, it's either vasilia, which we might translate as monarchy, or politia, which is polity. And politia in Greek, politi, is a Greek translation of Latin res publica. Res publica doesn't mean republic the way we mean it for the Romans, like a non-monarchical regime, right?

• 2:28:23Speaker 01

  That's how we mean like the American republic or, you know? That's a usage that came in later, like during the Enlightenment. In Latin, a res publica is the common affairs, the common interest of a people who are constituted as a political community, regardless of the type of regime that they have. Now, even Cicero could imagine the Roman res publica governed by a king, or by a senate, or by a democracy. And they continue to use that term. We don't use it according to Roman norms. We use it according to modern norms, the term republic. So they continue to call it a res publica or a politi under the emperors as well. Right? And it was understood that the role of the emperor, whether he's Caesar, or vasilefs,

• 2:29:07Speaker 01

  or whatever, whatever language, was to serve the politi. They keep saying this. So the terms that occur in the sources for Most commonly are Vasilia of the Romans, Polity of the Romans, or Romania, which is the proper name of this state. Not empire. Now, empire. Empire, in modern English, commonly, an empire is a state that's created when one group conquers a bunch of others and rules them. It could be an ethnic group. It could be an ethno-religious group. It could be a political group, whatever. But it's an act of conquest and results in a state where one group is ruling over others. That's not how Romania is actually constituted. We've talked about this.

• 2:29:51Speaker 01

  It's, for the most part, all Roman citizens ruling themselves, like Roman subjects, ruling themselves through their own government. So it's not an empire, strictly speaking. Now, occasionally, they will conquer other people. Like, we talked about the warfare. Sometimes it's not just offensive. Sometimes it's offensive, right? In that case, you do establish an imperial relationship. Like, we, the Romans, are ruling over this other group. It could be Slavs. It could be Bulgarians for a while. It could be whatever. Or even some Muslims in northern Syria for a while in the 11th century. And you are not Romans. And that's an imperial relationship. The question is, how many of these imperial relationships

• 2:30:34Speaker 01

  do you need to decide that, well, we've reached a tipping point and now we're just going to call the whole thing an empire? Personally, I don't think we ever reached that point. I mean, all states, even today, have minorities. Some of them are part of that state because they were conquered once upon a time. But we don't call those states empires necessarily. Even though, like, look at the United Kingdom. Well, Wales was conquered. And, you know, the Welsh have their own identity, their own language. But I don't know that you would call that now an imperial relationship. Maybe. I don't know.

• 2:31:15Lex Fridman?

  I think there's also a synonymous use of the word empire that refers to the power that the state has in the global context geopolitically. So sometimes empire is used synonymously with superpower, meaning it's one of the primary... Nations in the world, and it doesn't necessarily have to do with the imperial nature of its history.

• 2:31:40Speaker 01

  That's true.

• 2:31:40Lex Fridman?

  Hence, these sort of American empire, US empire.

• 2:31:43Speaker 01

  Yes, though you would never characterize the American political regime as an imperial one, insofar as it does not have an emperor, for example, but anyway.

• 2:31:55Speaker 01

  Yes, the problem is that in my field, we use the term empire conventionally, even when what you just described is clearly not happening, like even toward the end. It's not a major world power, it like has a few islands in the Peloponnese, but we call it empire and the emperor, and it's like, it's completely ridiculous, there's not even a term in their language for that sort of thing.

• 2:32:19Speaker 01

  Anyway, we can call things whatever we want, just so we understand what the reality is and what we are using those terms to mean. I think that's the important thing, yeah.

• 2:32:28Lex Fridman?

  So then, let's look at words which are both fascinating, monarchical republic.

• 2:32:34Speaker 01

  Right.

• 2:32:35Lex Fridman?

  Why is that a good term for the East Roman Empire?

• 2:32:40Speaker 01

  Because they understood it very much to be a polity in the Roman sense of a res publica, that was governed by a regime that was monarchical.

• 2:32:48Lex Fridman?

  So those two elements, there's an emperor due at the top, and it's functioning politically like a republic.

• 2:32:57Speaker 01

  Also, the emperor was expected to be working for the republic, like they keep saying this. So like, this was their conception. You don't find it, for example, in other kinds of dynastic empires, the ones that don't emerge from within the context of an ancient republic. So this is another reason why I find this civilization so fascinating, right? I mean, we mentioned the Greek and the Roman and the Christian elements that are kind of jostling together. This is fascinating to me in part because it's this weird combination of monarchical power, like in terms of executive institutions, and a republican kind of baseline ideology on which it operates.

• 2:33:41Speaker 01

  Yeah, and they sometimes come to a head.

• 2:33:44Lex Fridman?

  Is there at all a degree to which it's a military dictatorship? Because especially when it's a general in the emperor's seat, yes, there's republic, yes, there's political discussion, but the army has a lot of power. So to what degrees in a military dictatorship, as is sometimes talked about when you talk about the Roman Empire?

• 2:34:05Speaker 01

  Yeah, so Augustus's position, for example, and that of his successors is talked about as a military dictatorship. In other words, when push comes to shove and the basis of political power is the army, then I suppose it's legitimate for historians to talk about a military dictatorship. But here's why I don't think the Eastern Roman Empire is a military dictatorship, even though, again, the emperors control the armies and the armies themselves will often have a say in who becomes emperor, like through the civil wars that we mentioned. Okay. The reason why I don't think it's a military dictatorship is because they almost never,

• 2:34:49Speaker 01

  very, very, very rarely, use the army as an instrument of social control.

• 2:34:56Lex Fridman?

  Isn't that strange to you? Because you see that being done through so much of human history.

• 2:35:02Speaker 01

  Yeah.

• 2:35:03Lex Fridman?

  And the fact they don't resort to that, I mean, for a thousand years, that's just not a thing.

• 2:35:12Speaker 01

  As a way of keeping down the population, you just don't see it. And part of the reason for that is I don't think the population needs to be kept down. Like, this gets back to the consensus that we were talking about. The understanding is that the army is there to protect the Roman people and is often recruited among them. And for most of the period that I study is, like, lives among them. So when the emperors have to call up the army, they're literally calling up soldiers from local villages.

• 2:35:41Lex Fridman?

  It's just incredible that this worked. I guess the civil war thing is, as a mechanism, is effective. Because you just, throughout human history, I mean, you look at even recent history, it's just a very common thing for authoritarian figure to use the army to suppress people.

• 2:35:58Speaker 01

  Yeah, but isn't that dangerous, though? Look at how many modern regimes tried to use their own armies against their people who were in a moment of rising up. Well, it's a risk, like the Arab Spring, especially in Egypt.

• 2:36:15Speaker 01

  And you could you could tell for those three weeks that Mubarak was trying to decide whether he could actually count on the army to suppress the protesters or not, because you never know what they're going to do. If you ask them to fire on a civilian population, it can backfire on you badly. So I think that is a very dangerous force to use. And even in the context of modern regimes, can result in a regime change.

• 2:36:46Lex Fridman?

  Absolutely, and there's huge wisdom behind that. But, you know, leaders are not always wise, often not wise. And often, maybe they start out wise, but power corrupts them over time. And so the fact that this does not happen just over and over and over and over on the East Roman Empire is there's just signal there that's fascinating. And I mean, this goes to the book that you want to be working on about why the thing lasts.

• 2:37:12Speaker 01

  There's one emperor who does do that, and that's Justinian.

• 2:37:16Lex Fridman?

  Yeah, he gets wild.

• 2:37:17Speaker 01

  Yeah.

• 2:37:18Lex Fridman?

  So let's talk about Justinian. We have to, we have to talk about Justinian.

• 2:37:21Speaker 01

  Yes.

• 2:37:22Lex Fridman?

  One of the most impactful Roman emperors in history started as a peasant and rose in power to become emperor. He fought wars of conquest and was very consequential and impactful.

• 2:37:35Speaker 01

  Yes.

• 2:37:36Lex Fridman?

  So who was he?

• 2:37:37Speaker 01

  All right, so Justinian was the emperor from 527 to 565. So quite a long reign. He was the nephew of the previous emperor, Justin the First, who was an older man, ruled for just under a decade before Justinian. And both of them came from small, poor agricultural communities in the Western Balkans.

• 2:37:59Lex Fridman?

  We should say that Justin the First ended up in your worst 10 emperors list.

• 2:38:04Speaker 01

  Yeah, for one decision, he's not the worst of the worst, but he made a very, very bad call when it came to church policy, tore the church apart. He shouldn't have done that. In my view. By the way, Justinian is an immensely complicated figure. I found it impossible to decide, first of all, whether to put him on the best emperors or the worst emperors.

• 2:38:23Lex Fridman?

  Yeah, you're being spicy.

• 2:38:25Speaker 01

  Yeah, you have to be provocative about these things. And I thought omitting those two would be that. And it was. So, and here we are talking about it.

• 2:38:33Lex Fridman?

  Yeah, exactly, the controversy.

• 2:38:36Speaker 01

  And through the, all the systems of social mobility that we've been talking about, Justin ended up emperor. Because of his military background, he just rose through the ranks. He was in the right place, the right time, became emperor. And then he gradually positioned his nephew, Justinian, whose background we do not know. Literally, we do not know anything that Justinian did before the age of something like 38, when he appears on the historical record. Same background, we know where he came from, but we don't know what he was doing. Although, like, was he an active soldier for decades? We don't know. Probably not. He comes equipped with like, a knowledge of something like Roman law and some Christian theology. That seems to be like, what he knew.

• 2:39:19Speaker 01

  And then, Justin positions him to become his successor eventually, kind of reluctantly, but he does. Justinian also marries Theodora, who's a woman, who's a former sex worker, which is a controversial choice. By this point, he's a senator and is holding all of these top generalships. And then he becomes emperor.

• 2:39:41Lex Fridman?

  She was also very influential, yes?

• 2:39:43Speaker 01

  Very powerful, yes. During his, yeah, during his reign. So, the interesting thing about Justinian's choice of, let's say, associates, and that includes his wife, is that he seems to have just gone for people he, like, he thought were talented, or that would be good for him as a ruler, rather than their social class or prestige. And so, he accumulates around him quite a motley group of odd, sometimes, like, these kinds of disreputable people. But they did what he wanted them to, and they were, they were blasting consequences for world history. So, he has an eye for talent.

• 2:40:26Speaker 01

  And, and he doesn't hesitate to pick people that others might look down on if he thought they could get the job done. And these are some of the attributes that enable him to be as successful as he was. So, that's his background.

• 2:40:41Speaker 01

  He's a Latin speaker primarily, but he knows Greek too.

• 2:40:44Lex Fridman?

  So here he is, but he had, so like I mentioned, the wars of conquest. He also overhauled the Roman law.

• 2:40:51Speaker 01

  He appoints a committee.

• 2:40:52Lex Fridman?

  Yep.

• 2:40:53Speaker 01

  As one does, to just take the whole of Roman law and condense it into what today we call the corpus juriscuris, which is the body of Roman civil law. And this was a massive work of codification. And it is our main source for Roman law. Like overwhelmingly, what we call Roman law is what Justinian's committee, and specifically this character called Trebonian, who was a very accomplished jurist, said it was.

• 2:41:25Lex Fridman?

  And that, did that persist through time? Did that last?

• 2:41:27Speaker 01

  Yes, still to this day. When you study Roman law, you're studying Trebonian's committee.

• 2:41:34Lex Fridman?

  And so in terms of our modern society, how much of impact did that have? This codification, this stable law that ran the East Roman Empire?

• 2:41:44Speaker 01

  Well, I mean, Roman legal concepts pervade everything from philosophy to political thought to actual Roman legal practice. I mean, depends on what country you're in. So in many of the countries of Europe, it is the, you know, current law. And it is to some degree, I mean, I'm exaggerating, but legal scholars have to study Roman law. Even, even law students have to do that. Not in so much in countries like the United States or Britain, which have the so-called common law system. But ideas in Roman law about, for example, property, right? Ownership, things like this. These were hugely important in formulating ideas, for example, about sovereignty in political thought.

• 2:42:28Speaker 01

  Yeah, it's one of the most important and influential acts of committee work ever done in Constantinople.

• 2:42:34Lex Fridman?

  So going to perplexity here and looking at some aspects of the Justinian's laws. They include a systematic structure of private law, persons, things, actions, strong protection of property and contracts, detailed family and inheritance rules, and a hierarchical status-based view of persons. These elements became the template for later civil law systems. And some overall structures, tripartite schema, law organized around personae, legal subjects, things, and procedural actions, essentially who, what, and how of private law. And it

• 2:43:16Lex Fridman?

  goes on. I mean, a lot of things I'm reading here really sounds like what we think of as law.

• 2:43:22Speaker 01

  Yeah.

• 2:43:23Lex Fridman?

  Marriage.

• 2:43:24Speaker 01

  Look, most of it's about property.

• 2:43:25Lex Fridman?

  Yeah.

• 2:43:26Speaker 01

  Yeah.

• 2:43:27Lex Fridman?

  Marriage is a legal status. Lawful matrimony required conformity to rules about age, citizenship, and canobium or prohibited degrees, incest rules, adoption relations, et cetera. All that kind of stuff.

• 2:43:42Speaker 01

  Oh, yes. Who you can marry, who not.

• 2:43:44Lex Fridman?

  What was their view of homosexuality?

• 2:43:47Speaker 01

  Well, I mean, Justinian thought it caused earthquakes.

• 2:43:49Lex Fridman?

  Dog did it.

• 2:43:52Speaker 01

  Yes.

• 2:43:53Lex Fridman?

  Did it.

• 2:43:54Speaker 01

  Yes.

• 2:43:55Lex Fridman?

  Fascinating.

• 2:43:56Speaker 01

  No, for him, no, so for Christian emperors or Christian authorities, this is reprehensible immoral act. Depending, it could be punished. Justinian did try to punish it pretty brutally. I mean, ultimately lethally. However, this gets really tricky here because what counts as a homosexual act is not clear to everybody, right? And in addition to which.

• 2:44:33Speaker 01

  There, this is a society that generally will not go after,

• 2:44:41Speaker 01

  let's say scandals or deviance, or however you want to call it, like systematically. This is not like some, there's no inquisition. There's no social police. If there's some sort of scandal and this comes out, then it's a problem. But they're not actively going to track down, hunt down, monitor, survey, interrogate people about their sex lives. I mean, it's, it is in a way, despite having views that we, we may not agree with about sexuality.

• 2:45:16Speaker 01

  It was, it was, it was generally humane in the way of just kind of leaving people alone.

• 2:45:22Lex Fridman?

  I mean, that said, there's some, I'm just, on perplexity, I looked up Justinian Roman Law view of sexuality. They're pretty harsh and like adultery and just getting freaky with it.

• 2:45:36Speaker 01

  No, Justinian was more zealous in this matter, definitely.

• 2:45:41Lex Fridman?

  Even though he married a sex worker.

• 2:45:46Speaker 01

  Well, sex work wasn't illegal.

• 2:45:49Lex Fridman?

  Right, but it's a bit spicy.

• 2:45:51Speaker 01

  Yes, and in fact, it was illegal for a senator to marry someone from such a disreputable profession. And he got his uncle to pass a law changing that rule so that he could.

• 2:46:04Lex Fridman?

  Well.

• 2:46:05Speaker 01

  Yeah.

• 2:46:05Lex Fridman?

  Love knows no bounds.

• 2:46:07Speaker 01

  Actually, Justinian kind of says that in one of his laws.

• 2:46:10Lex Fridman?

  Oh, well.

• 2:46:11Speaker 01

  No, he clearly loved her. There's no question.

• 2:46:13Lex Fridman?

  Actual love. I mean, this, you'll have to like this guy. Starts as a peasant, surrounded himself by all kinds of weirdos just because they were good at what they did and it doesn't really matter class or not.

• 2:46:24Speaker 01

  Yes, but there's a lot to be said against him, too. I liked so much.

• 2:46:31Lex Fridman?

  Let's get into it. So he didn't launch wars of conquest. What was his view of war and conquest and what maybe what are the things we should mention in terms of expansionary wars?

• 2:46:43Speaker 01

  He thought he was authorized by God to reconquer the lost provinces of the Western Roman Empire. And when he did so, that was proof that God favored him. And he was generally opportunistic about it, and for the most part, kind of successful in that he intervened in the most critical moments of the histories of these barbarian, you know, kingdoms in the West and exploited their weaknesses and took them over. Now, in the process, many of these provinces were ravaged by war, Italy for decades. He overstretched his resources, leaving his successors with a much more dangerous situation to defend.

• 2:47:25Speaker 01

  And he disbanded certain armies that were meant to protect Constantinople, sent them to Italy, for example. This weakened the home front. So he left a very difficult legacy for his successors in that way. Plus, some of the provinces that he conquered were so, like Italy, I don't think it could even pay for itself after a certain point. So I'm not sure that some of those decisions were the best ones. North Africa, yeah, probably that paid off. Italy and Southern Spain, not so sure.

• 2:47:55Lex Fridman?

  So that's one of the big criticisms is even though there was conquest, it was overextended and those lands were not economically stable.

• 2:48:06Speaker 01

  Yeah.

• 2:48:06Lex Fridman?

  Broke.

• 2:48:08Speaker 01

  Yeah.

• 2:48:08Lex Fridman?

  AKA.

• 2:48:09Speaker 01

  Conquest is not just good, you know, in itself. I mean, this is, I know that some rulers in history are called the great simply because they conquered something, but that's, that's not enough. I mean, I know that rulers do this, but if we're to compare them to each other, we should at least expect that they have a plan or that it works out well in the end, let's say. And I don't think that many of these did.

• 2:48:33Lex Fridman?

  I should say that as far as historians go, I think you don't give too many points on the conquest front.

• 2:48:42Speaker 01

  Personally, I, yeah, I don't.

• 2:48:44Lex Fridman?

  Yeah. So your value comes from, is a leader implementing lasting?

• 2:48:51Lex Fridman?

  Change, like a stable.

• 2:48:53Speaker 01

  Was he good for his subjects?

• 2:48:55Lex Fridman?

  Yeah.

• 2:48:55Speaker 01

  Were they living better because of him than otherwise?

• 2:48:58Lex Fridman?

  And also like longer, like the long-term nature of it, not just,

• 2:49:03Speaker 01

  Yeah.

• 2:49:04Lex Fridman?

  not just like a temporary thing.

• 2:49:06Speaker 01

  Right. Are you strengthening institutions that benefit your subjects? That. And some he did, some not. So, look, in order to send those armies west to make those conquests, he stripped the east of armies. So the Persians could just march in and like destroyed Antioch. Like, that's a major strategic failure. And I don't think you get a pass for conquering North Africa by surrendering Syria.

• 2:49:32Lex Fridman?

  He did rebuild Constantinople and reconstructed the Hagia Sophia?

• 2:49:37Speaker 01

  Yes, after he and his soldiers set fire to it, yes, in the Nika insurrection. So this is when the people of the capital rise up against him. And there's like about 10 days of street fighting and he brings in some armies. And eventually, he orders his armies to slaughter the protesters, leaving more than 30,000 dead. Like, this is an enormous number. And a lot of Constantinople burned in the process. And yeah, he rebuilt it. So his building is considered one of his great points. He built a Yassofia, for example, which is a magnificent church, like, hands down. It's just a fascinating monument to study, too. And yeah, that was, that was him, too.

• 2:50:19Speaker 01

  I'm trying to give you a sense here that the good and the bad are mixed in such equal measure that, like Burden's ass, I can't decide which, which bale of hay to put him on.

• 2:50:28Lex Fridman?

  But there's a grand scale to the good and the bad.

• 2:50:30Speaker 01

  Yes, yes.

• 2:50:32Lex Fridman?

  For many people, that's what makes for a

• 2:50:34Speaker 01

  Exactly.

• 2:50:35Lex Fridman?

  top 10 emperor list. What about the plague?

• 2:50:39Speaker 01

  Well, he wasn't responsible for that, at least.

• 2:50:43Speaker 01

  Okay.

• 2:50:43Lex Fridman?

  The plague of Justinian.

• 2:50:45Speaker 01

  Yes.

• 2:50:45Lex Fridman?

  AKA 541 AD. So some historians claim that it killed half the population and ruined the empire. You are skeptical on this view?

• 2:50:55Speaker 01

  Yes. So this is A bubonic plague, which lasts more or less for two centuries. It comes and it goes, and it's kind of endemic to large parts of the world. 541 is when it starts to break out in the empire and Constantinople and other cities, and it spreads. There's been a lot of debate about this recently because now we've actually isolated the pathogen. It's Ersaniaspestis, like we know this. Just like a generation ago, this was just guesswork. But now there's all of this new laboratory science work that's come in to fill in some of the gaps in history. That's so cool. It is, it is. There are lots of discussions about that.

• 2:51:37Speaker 01

  And so the study of diseases and virology have just become much more important lately. It still doesn't tell you, however, mortality rates and historical impact. For that, you still need standard, old fashioned, non-laboratory historical work. And there's a debate about the impact of this plague, and it's ongoing, I should say that. And some scholars argue for a maximalist position of 50%. I think that would have brought this society to a halt, just logistically speaking. And so I believe in a much more moderate impact. And the real impact is what? The tax base shrinks? Oh, oh, yeah. The tax base would shrink instantly.

• 2:52:22Speaker 01

  You wouldn't be able to recruit armies. There would be massive social dislocation, like what happens in the Black Death in Europe in the 14th century. We have very good records for what happened to those societies, and basically, everything that they were doing stopped for a few years until they tried to put things back together again. This does not happen in the 6th century. In fact, Justinian is at that time waging war on something like four or five different fronts. If you read the narratives of those wars, there's no pause, there's no, there's no impact from the plague on the conduct of those wars. They just continue on. Taxation continues, the courts continue, like you just don't see it in the narrative.

• 2:53:07Speaker 01

  And so I think that there is a much less impact than certainly than 50%. Yeah.

• 2:53:12Lex Fridman?

  So this sets the stage for tumultuous seventh century.

• 2:53:18Speaker 01

  Yeah, you could call it that. Yes.

• 2:53:21Lex Fridman?

  So what, what is the legacy of Justinian? In terms of how he left the empire, leading in to the seventh century?

• 2:53:31Speaker 01

  Well, he left it overextended. So his successors had to deal with many more problems along many more fronts. With fewer military forces concentrated in what we might call the homeland of the Eastern Roman Empire. And so that made the, the center vulnerable too. And so you start to get raids into the Balkans and, you know, it enters a kind of vicious cycle again.

• 2:54:00Speaker 01

  Now, not all of this was Justinian's fault. I mean, the plague definitely had some impact.

• 2:54:06Speaker 01

  But I wouldn't blame everything on his successors, as is sometimes done. Like they mishandled the situation. He, yeah, he left them a very difficult situation to deal with.

• 2:54:20Lex Fridman?

  So speaking of which, let's talk about Herakles.

• 2:54:24Lex Fridman?

  He didn't make, he didn't make your list either, which is a shocker for a lot of people. Perhaps you can describe the nuance of that, but he took over the Roman Empire on the verge of extinction. Persians at the gates, treasury empty. So maybe first tell the full saga of the Roman Persian War that threatened the empire's existence.

• 2:54:46Speaker 01

  Sure. Well, he, he wasn't entirely, you know, free of blame for the situation that he inherited. He was in part responsible for it. So, so he doesn't get a pass on that. So Herakles is basically a rebel and a usurper. So for various reasons, Rome and Persia are at war.

• 2:55:09Speaker 01

  Starting around 602, and the Persian Shah at this time, Qusro II, has basically decided on a policy of conquest, not just raiding. Like, I'm gonna go in and take your people, some cattle and some statues, and take them to Mesopotamia. He starts what, I mean, I think there's some evolution in his thinking and his planning about this, but pretty soon during the 600 and the aughts, he realizes that there's potential for actual permanent territorial gain here, and his armies start moving in. And the Roman emperor is this guy called Fokas, who is himself a usurper, a military background. And he now faces a rebellion by Heraclius,

• 2:55:52Speaker 01

  who's base is in North Africa at this time, like around Carthage. And they have a civil war for three years, 608 to 610. That civil war that Heraclius initiates causes a diversion of Roman armies to the civil war away from the Persian front. So it's a massive gift to the Persians. Plus, a lot of the fighting takes place in Egypt. And Egypt was a province that had, up until that point, not really been harmed by war. Now it is. Right? So Heraclius's forces, he's not in Egypt, but his backers are fighting a civil war in Egypt.

• 2:56:32Speaker 01

  So that's, province is now ravaged, in part. The Persians make tremendous gains in the east. Heraclius heads straight for Constantinople during all of this. And to make a long story short, he manages to take Constantinople, execute Fokas, and become emperor. Right? But now he's facing a problem that's much worse than it was before he started the rebellion. The reason why Heraclius is sort of lionized in some... Well, actually, there's a very long tradition of doing this, which goes back to the Middle Ages. In the Western Middle Ages, Heraclius was sometimes considered like the first crusader.

• 2:57:10Lex Fridman?

  Interesting.

• 2:57:11Speaker 01

  Yeah, yeah. So there's all this medieval literature about Heraclius as being a proto crusader type and all that for reconquering Jerusalem from the Persians and restoring the True Cross and all that. So he had this kind of aura. And I think his modern admirers are basically just continuing, I mean, they might not know it, but they're kind of continuing this very, very long tradition of treating Heraclius as this heroic holy warrior. Anyway, from my standpoint, it's a complete wash. In other words, yes, he does beat the Persians. And he gets, like, in my view, full credit for that, though he did it with, I think, the

• 2:57:54Speaker 01

  help of some Turkish allies from Central Asia. These were, I think, the major component of his success at the very end. But no, no. So he held the Persians off and ultimately defeated them. Yes. And then he loses everything to the Arabs.

• 2:58:09Lex Fridman?

  So the Arab conquests are 630s and 640s, but the Persian War is 602 to 628?

• 2:58:17Speaker 01

  Yes.

• 2:58:17Lex Fridman?

  So what can be said about this, what seems to be a pretty costly war against Persians?

• 2:58:25Speaker 01

  So the war was costly initially only for the Romans. The eastern provinces were conquered by Persia. That means Syria, Palestine, Egypt. So that's a loss. You lose all that revenue. And then they start raiding into Asia Minor. By the way, this is exactly what the Arabs would do, you know, just a couple decades later. They would conquer Syria, Palestine, Egypt, and they would start raiding into Asia Minor. So almost like this phase of East Roman history begins already during the Persian invasion. It's just a kind of a prelude. It was in fact the Arabs that would do that for the next few centuries. So Heraclius,

• 2:59:03Speaker 01

  it takes him a very long time to get organized. In fact, something like 15 years. And it's not entirely clear, like, what he's doing all this time. But he ultimately manages to defeat the Persians by waging these Really spectacular, weird campaigns in the east. He decides to strike into the Persian heartland, as it were. Well, first in the Caucasus region, and then he goes into Mesopotamia. So not to try to defeat their armies that are rampaging around Asia Minor, or even besieging his capital in 626.

• 2:59:42Speaker 01

  The Persians and the Avars, this nomadic warrior group that's settled in roughly modern Hungary, they're besieging Constantinople. Heraclius doesn't even go. And he's just kind of preparing his armies in the east. And he strikes the Persians right where it hurts. And this now begins to degrade the Persian heartland and their infrastructure. Because remember, both of these empires are going to be in shambles by the time the Arabs come along. And this is what enables the Arabs to conquer them so quickly. And they've destroyed each other in these wars. And eventually Heraclius calls in his Turkish allies and they go on a field trip through Mesopotamia. And this causes a coup in Persia and Cusro is killed.

• 3:00:27Lex Fridman?

  Is there something to be said, a little bit of texture, to the motivations of the different empires and the different groups involved? So the East Roman Empire, the Persian Empire, and the Islamic Caliphates, were they after conquering? Were they after expansion? Were they after more like raiding for financial benefits? What was the motivation?

• 3:00:49Speaker 01

  So in the past, the Persian shahs basically were interested in raiding. And they also had an interest in manpower. So all of those Mesopotamian agricultural estates won't till themselves. So they were kind of insatiable for agricultural workforces and specialized craftsmen and people like that. So they would go into the empire and get them. But in this phase, it seems that Cusro II is taking really to heart the idea that the Persian Empire should really extend to the Mediterranean, as it did in like Akhenaten times, right? In ancient history, the empire that Alexander conquered. So it seems that the Sassanians, this is this dynasty, this Iranian dynasty, that's ruling the Persian Empire. The course they were aware of the Achaemenids,

• 3:01:33Speaker 01

  but sometimes they would have these claims to reviving the former greatness of the Iranian empire.

• 3:01:39Lex Fridman?

  Sure.

• 3:01:39Speaker 01

  So bathing in the Mediterranean Sea is something that many Near Eastern monarchs, they did this as a sign of success. Anyway, for the Romans, it was sheer survival, just desperate survival because they knew that this was a war that could end the Roman state.

• 3:01:59Lex Fridman?

  I mean, they're already on the verge of being ended.

• 3:02:03Speaker 01

  Yeah.

• 3:02:03Lex Fridman?

  And here they're defensive wars of survival.

• 3:02:08Speaker 01

  Yeah, so it's pretty clear that initially, the goal of Arab Muslim warfare is to unify Arabia. That is, that all Arabs should be Muslim and should be unified into this religious kind of state, whatever, that the prophet and his successors had created. Now, then they start striking out into Rome and into Iran. It's not entirely clear like why. Now, there are obvious reasons. I mean, we don't, it's not like a huge historical mystery why a recently formed, successful army

• 3:02:51Speaker 01

  will decide to take on two very weak opponents who are on their doorstep. Like, this is not complicated.

• 3:02:58Lex Fridman?

  Yeah, they're pretty effective at military conquest.

• 3:03:01Speaker 01

  Yeah, but they're striking both empires from a direction that those empires had never prepared to defend from. Arabia was just not, oh, you might get some occasional raiders. You're never going to get an army that's coming out that can potentially conquer you. So the defensive orientations are all wrong. And these two empires have gone through this massive war that has destabilized them. They're low on manpower, low on resources. The outcome is almost kind of inevitable. I don't think there's a great mystery.

• 3:03:33Lex Fridman?

  And the effect of that is they stripped away the richest provinces of the Roman Empire.

• 3:03:40Speaker 01

  Yes, Egypt in particular. And that means now you can't feed Constantinople. Like, we talked about the grain from Egypt, right? That came to Constantinople. You don't have that now. And so that means that the population of Constantinople will decline dramatically over the next few decades.

• 3:03:57Lex Fridman?

  So how does the empire rebuild itself? You know, restabilize because it's not, it doesn't collapse there, right?

• 3:04:05Speaker 01

  Yes.

• 3:04:05Lex Fridman?

  It stays, it survives. There's interesting low points for the empire where it still survives.

• 3:04:12Speaker 01

  This is one of them.

• 3:04:13Lex Fridman?

  And that is as interesting as the survival at the top. And the flourishing, survival at the bottom is also super interesting. So how, what, what, what happens? How does it kind of stabilize?

• 3:04:25Speaker 01

  Very slowly. This is a painful process and it takes them centuries, you could say.

• 3:04:32Lex Fridman?

  Yeah.

• 3:04:32Speaker 01

  First, you gotta stop the bleeding, just try to hold the line. It takes them decades to just to hold a line. Like they get pummeled by the Arabs for decades in the seventh century. Until finally by, ah, six, six sixties, six seventy, they finally begin to beat them. Beat them on land and, and hold the line on the sea. And so we now have an investment in fleets. Eventually you get the Greek fire, which is the flamethrowers. And when the Arabs try to take Constantinople, these attempts are defeated like twice.

• 3:05:14Speaker 01

  And that ensures the survival of this, of the Roman state in some form.

• 3:05:20Lex Fridman?

  How were the flamethrowers used?

• 3:05:23Speaker 01

  Ah, yes, this is an interesting question. We're still kind of debating that.

• 3:05:26Lex Fridman?

  Oh, it's not fully understood.

• 3:05:27Speaker 01

  Well, it's a state secret.

• 3:05:30Speaker 01

  They didn't want this getting out, so they kept it pretty well. The fact that we're debating it will tell you that they were pretty good at keeping secrets. So possibly through a, a pressure valve. Right? So you have this flammable compound whose preparation and components is also a state secret. So there's specialized, there's a corps of engineers that, that prepares this and deploys it. And it's possibly through a heated, pressurized container with this spigot, let's say, that unleashes this thing through a nozzle and.

• 3:06:10Speaker 01

  And it's lit and basically spews flaming napalm on other ships. And it will continue to burn even when it's on the water, right? On the top. So like you can't like swim away or anything. So this is very, very destructive weapon, terrifying. They used it against Vikings too. This is much later. So once the Vikings show up, like when they would raid, attacked Constantinople in the 940s, then again in the 1040s. Yeah, the Romans used Greek fire fleets to just incinerate them. And that'll teach Vikings.

• 3:06:52Speaker 01

  Yes. If you're in, if you're in that situation, you'd rather serve under the emperors than attack them.

• 3:07:00Lex Fridman?

  And so this is, this is kind of nuclear weapon level state secret.

• 3:07:03Speaker 01

  They even had it in hand grenade form.

• 3:07:07Lex Fridman?

  This is a real thing?

• 3:07:08Speaker 01

  Oh, yes.

• 3:07:09Lex Fridman?

  Hand grenade form?

• 3:07:10Speaker 01

  Yes. So it's a, it's like a clay container with the compound. And it has like some sort of fuse that you light on the outside and you throw it. Now, you throw it, you can throw it against people. It's not going to be that effective. Maybe you burn a person, whatever. You just wasted a hand grenade for, you know, one person. It's most effective against things like a siege engines.

• 3:07:34Speaker 01

  So you, you throw that on a wooden frame and you know, yeah.

• 3:07:38Lex Fridman?

  This is incredible. So this is one of the things that's finally stabilized.

• 3:07:43Lex Fridman?

  Stop the bleeding from a military perspective.

• 3:07:45Speaker 01

  Yeah, eventually. Now, now remember they've pulled the armies back into Asia Minor. So they're, they're beginning to defend and fortify Asia Minor. Now you have to find ways to pay and support and feed all of these soldiers. And this is a whole administrative, it's a wrenching administrative readjustment. But they go through it. It takes them a long time. Eventually they emerge with a different kind of strategic logistical system.

• 3:08:08Lex Fridman?

  Just a smaller, harder core of the empire.

• 3:08:13Speaker 01

  That's right. Very militarized.

• 3:08:15Lex Fridman?

  Very militarized.

• 3:08:16Speaker 01

  Yeah.

• 3:08:17Lex Fridman?

  Then in the eighth century, the, the, the second Arab siege of Constantinople that somehow fails.

• 3:08:24Speaker 01

  In the early eighth century, yes, that was the second siege.

• 3:08:27Lex Fridman?

  Yeah, the early eighth century. So why, why did it fail? Can you tell the story of that siege? That was really the empire hanging by, by a thread.

• 3:08:36Speaker 01

  Yes, but it happened to have a very competent man in charge. This is Leo the Third, and he's an emperor who has, he's a usurper. He's just seized power. They knew that this massive Arab attack was coming. And so it's quite possible that the Roman elites, you know, preferred to put someone capable in, in power at that moment. The city was very well prepared. I encourage people in the audience to, to go and read the, the sources that we have for that. You, you can find many accounts of it online. It, it was just very, very well done. He also had Bulgari allies. So these are the, the Bulgari who had just, you know, crossed the Danube, just like, just a few years earlier, actually,

• 3:09:17Speaker 01

  and settled south of the Danube, um, you know, where eventually, you know, Bulgaria emerged. So he had Bulgari allies and he used the, the Greek fire very, very strategically. He used his own fleet. He contained the Arabs to certain places where they kind of starved and wore them down. It was just very well done.

• 3:09:36Lex Fridman?

  From a military perspective?

• 3:09:37Speaker 01

  From a military perspective.

• 3:09:39Lex Fridman?

  Well, was there, was it the, uh, the walls, the navy, the weather, the diplomacy? Just good luck that helped Constantinople hold?

• 3:09:51Speaker 01

  I don't see much role for good luck there. I mean, I think he had it all pretty planned out. It was all of the elements that you mentioned. And yeah, he, he just deployed them very, very astutely. Um, and went on to rule after that for another 20 some years. And, um, his son continued, um, they formed a dynasty. We call it the Isaurian dynasty, though they were not from Isauria.

• 3:10:12Lex Fridman?

  And then from that, the fascinating thing that we mentioned about religion, there is a whole stretch of time. Marked by intense internal religious conflicts over iconoclasm. Maybe you can clarify this, but so iconoclasm, of course, is whether sacred images, icons, should be venerated or destroyed. This had major political and theological stakes. The seemingly smallest things can have the biggest of conflicts.

• 3:10:41Speaker 01

  Yeah. You've been in an Orthodox church. Have you seen all the icons in the just painting everywhere? Every, every space that you can imagine is covered in either icons or images or iconography of saints. All right. That's a result of this. No, that's not what Christian churches used to be like, at least not in Constantinople. But his dynasty basically tried to limit or remove images from churches. And ultimately, that policy failed. And the other side that wanted images or liked images, and put differently, thought that images were not only appropriate, but helpful in the context of Christian worship, prevailed.

• 3:11:25Speaker 01

  And so gradually, the churches began to fill up with icons, lots of icons. They're almost like, you know, like a catchword for Orthodox, you know, devotion. I have icons at home. You have a little corner in the house, you have a little iconography. Anyway, I mean, as a secular Orthodox person, but I, even I can't get away from them.

• 3:11:48Lex Fridman?

  But that has serious consequences. I mean, there's serious, there was an extremely serious internal religious conflict.

• 3:11:54Speaker 01

  Well, okay, so one asterisk on that. In my research, I did not find a popular interest in this matter.

• 3:12:04Lex Fridman?

  Oh, interesting.

• 3:12:05Speaker 01

  Yeah, I, yeah, I don't.

• 3:12:07Lex Fridman?

  So this is an overblown?

• 3:12:08Speaker 01

  Yes, yes, socially, completely overblown.

• 3:12:11Lex Fridman?

  Oh, this is one of those things where religious folks will write the story of history.

• 3:12:16Speaker 01

  That's it, got it. You got it. I could not find, there were like a few emperors, and there's some bishops and abbots and monks, like, I don't know, maybe a hundred, 200 people are like seriously invested in this and they're going at it. But these are the people who write the texts. But they never mentioned, for example, that, oh, you know, the, the people of Constantinople, they rose up and they demanded icons or not icons or anything like that. No, never. So in my view, this is one of those controversies that's only a few people really, really cared about it. And unfortunately, they're the ones who wrote the sources.

• 3:12:58Lex Fridman?

  So you always have to be very careful to consider the sources when you're reading about anything involving religious events.

• 3:13:07Speaker 01

  Or any kind of events.

• 3:13:09Lex Fridman?

  But certain, certain things are more intensely, people are more intensely passionate about and therefore they're going, that bias is going to bleed into the way you report the history.

• 3:13:21Speaker 01

  And not only that, when emperors changed their policy, almost everyone fell into line. They switched positions. It's like, yeah, whatever. Put the images, take the images, like, whatever. Like, this isn't, they did not see this as central. Some people did. And they got very worked up about it. Anyway, but in the end, the pro icon position won, and their view just began to fill up the space. Like, it literally was filling up the churches. And it still does. Yeah.

• 3:13:55Lex Fridman?

  The thing is, we somehow took on the impossible task of talking about a thousand.

• 3:14:03Speaker 01

  It'll defeat you, man. It'll defeat you every time.

• 3:14:05Lex Fridman?

  I mean, there's a reason why you really want to do a thousand hour podcast on this, right? As, as, as you do, as there's so many incredible conversations about every single emperor, every single nuance detail of the emperor. It really is a thriving civilization, is a thriving empire, which in it contains so many lessons for even the modern times. But anyway, you have written, one of the books is Streams of Gold, Rivers of Blood, The Rise and Fall of Byzantium, 955 A.D. to the First Crusade. So this period has, we talked about survival and some low points. This is a period where, once again, there's

• 3:14:46Lex Fridman?

  some flourishing. So by the 10th century, in the Macedonian era, the empire is back.

• 3:14:54Lex Fridman?

  It's wealthy, it's culturally confident and under emperors like Bezo the Second, who I think is in your top 10 list. It is expanding again, and this is the period you describe in part in your book, Streams of Gold, Rivers of Blood. So how did Byzantium go from surviving to expanding again?

• 3:15:16Speaker 01

  So I wrote that book in part in order to test myself and see if I could write narrative. So I hadn't written a history narrative book up until that point. Everything I wrote was sort of analytical, right? And it was successful enough that a few years later, my editor asked me to write the big history, the New Roman Empire, the thousand-

• 3:15:39Lex Fridman?

  Of the whole thing.

• 3:15:40Speaker 01

  Of the whole thing. And so I set for myself the task of explaining in this book, Streams of Gold, Rivers of Blood, a very particular period that was marked by a sudden turn to conquest again after a long period of more or less defensive war. 955, there's a new military leadership is appointed and the Romans go conquering again, especially in Solicia, northern Syria, and Cyprus and the Caucasus, and then eventually also Bulgaria. And then right afterwards, they have this generation plus period of stability and prosperity,

• 3:16:23Speaker 01

  and then they're hit by a triple whammy. These are three new attackers. So it's primarily the Seljuk Turks coming in from the east, some Pecheneghs coming down from the north over the Danube, and the Normans in southern Italy. And under the pressure of this three-part attack, the, you know, this expansionist, what had become more imperial state buckles and enters another one of these crises, just like the one we described for the seventh century.

• 3:16:59Speaker 01

  You know, survives it by the skin of its teeth and goes on again to rebuild and become prosperous, wealthy and powerful again, as it does throughout its history. It's these cycles. So I just wanted to describe that iteration of that, that process. And that's what I do in, in that book.

• 3:17:18Lex Fridman?

  So I think the traditional view in this perfect storm of the 11th century is that it was more to do with the internal sort of moral decay and civilian emperors neglecting the army, this internal stuff. And you make the case that it's the external stuff, the three-pronged attack, like you said, Normans in the West, the Turks, that people in the North and Central Asia, the, the Turks in the East. Can you describe that, the three forces in the case that that was the main reason why Hitler low?

• 3:17:58Speaker 01

  Well, this is also a methodological problem, right? In other words, when you're looking at a society that suddenly faces a bunch of problems and you could, you know, reasonably make the case for a kind of decline or a crisis, is your instinct, is your first instinct to suppose that there must be something wrong in the internal mechanisms of that society that, you know, led it to fail? Which is what my field has done traditionally, in part because of the decline and fall model, right, of, of this society, we're kind of primed to think that there was something wrong with it. That's a long story.

• 3:18:34Speaker 01

  Or is it reasonable to say that a society that does not seem to have any like particularly serious structural flaws is hit by external, you know, challenges that it couldn't realistically have foreseen or prepared for, such that, you know, it couldn't cope with them and, as I said, buckled? And I think that's what happened. I think that's the, the main narrative. Not that there weren't problems, there were. But. No state can, medieval or ancient, can realistically survive the simultaneous attack of three very different kinds of enemies.

• 3:19:19Speaker 01

  The Normans are like these knights, like a new type of Western warfare that is just all about grinding the enemy to bits, but who are also terrorists, like they're straight up terrorists.

• 3:19:33Lex Fridman?

  Normans are fascinating because I mean, there's a Viking component to the Normans. That's a whole. So they have three different kinds of enemies.

• 3:19:43Speaker 01

  Yes, the Pechonegs, who's a totally different type of, probably mostly nomadic horsemen. And then the Seljuk Turks, who are also mostly nomadic horsemen, but who are coming in from Central Asia with vast reserves of manpower behind them. In fact, either intending to, or as it happens, affecting a demographic change in, not just demographic, but ecological too, because they basically, when they move into Asia Minor, they're transforming or terraforming agricultural land into pasturage. And they're just backed by reserves of manpower

• 3:20:26Speaker 01

  that no other enemy of the empire has had yet. So yeah, how do you cope with these situations? I mean, it's very, very difficult and it's a wonder that they survived it at all. Now, they also have internal problems. I'm not going to sort of try to sweep these under the rug, right? In particular, we're seeing the end of the Macedonian dynasty. This is a dynasty that had lasted for about two centuries. And this has a kind of politically destabilizing effect. New emperors, and there are a lot of like childless old men in this period, are relatively insecure. They don't have this kind of a dynastic glitz behind them. And so they're tending to buy a lot of political support,

• 3:21:10Speaker 01

  like hand out these exemptions, give cash, you know, titles to anyone who will support them. And this, of course, causes a budget problem. Like they don't have enough money after a while. And then they have to start raising all of these armies to deal with all of these problems. And that just increases the pressure on the budget. And so there is an internal problem as well. Yeah.

• 3:21:29Lex Fridman?

  So you mentioned this loop of. Thriving and then having to survive, surviving, that happens a few times throughout the history of the Roman Empire. It seems that societies in general oscillate in that way. Is there something particular you could say about the oscillations, the loops that the Roman Empire goes through?

• 3:21:52Speaker 01

  Yes. Now, I don't think this is an oscillation. At least, that's not how I think of it in my own mind. So as I explained, the crises that this polity, this state, this society that it undergoes, are, there are a discreet number of them. I can, I can tell you what they are, and we've, we've talked about most of them so far. They don't last very long, and they are all sudden challenges that appear from the outside. In other words, they're exogenous shocks that they can't really have prepared for. These shocks cause massive territorial loss, which requires adjustment, right?

• 3:22:37Speaker 01

  But they don't last that long. In other words, the Romans almost always, at some point, figure out how to hold a line, how to consolidate their position, regroup, and put their economy and their society back on a trajectory of revival, regrowth, and eventual reconquest. Always, every single time, except the last time, right? And for me, this poses the following kind of dilemma, which I can answer. And the dilemma is, should we define this society by these brief crises of exogenous shocks?

• 3:23:16Speaker 01

  Or should we define it by the centuries-long, sometimes, periods of regrowth, consolidation, and stabilization, which are endogenous? Nobody came from the outside to help them rebuild. And my answer is unequivocally the latter. So I see this as a society whose internal organization primes it to stabilize and embark on steady growth, slow and gradual, but steady. And that's what I would like my field to explain more. And I'm going to try to do so in the book I mentioned that I'm writing on like the longevity

• 3:24:00Speaker 01

  or the resilience of this society and not try to center the crises, which I see as being from the outside. Like, these aren't, of course, they're part of its story, but they're not coming from it. What's coming from it is the stability. And I think that's the more interesting part of this society.

• 3:24:19Lex Fridman?

  Yeah, so the, you know, these peak to peak histories, as you can think of them, they miss the machinery in the valleys, institutions, incentives, daily life, all of these things, the politics, the religion. You have a bunch of revisionist history ideas in your work. You're challenging the field.

• 3:24:38Speaker 01

  Yes, you could say that.

• 3:24:40Lex Fridman?

  In the best possible way. So just to linger on, what are some of the things that historians miss? So this is a big one, right, that you're speaking to, which is like focusing too many, too much on specific moments versus on the broad structural underpinnings of an empire, of a society.

• 3:25:01Speaker 01

  Right, so what you alluded to there is a critique of what we might call short histories of Byzantium, which is a kind of genre of a book. This isn't necessarily like what my other revisionist ideas are about. The more important ones are things like the monarchical republic that we talked about. In other words, that there's actually a broader spectrum of political participation, that emperors are having to look over their shoulders all the time, that there is a deeper matrix of Roman republican thought there. Like, that's one revisionist idea. Another one is about Roman identity, just like, who are these people? And they are Romans, and in fact, is kind of an ethnic identity after a certain point. Like, those kinds of ideas.

• 3:25:46Speaker 01

  The criticism of the peak to peak kinds of books. So if you're trying to condense 1,200 years into 120 pages, or even, you know, even 200 pages. There's no way to do so realistically and give a sense of the whole terrain. In other words, what these books do is they go, they jump from, from highlight to highlight. And these highlights are sometimes things like, you know, everything Justinian did, because it's so extravagant, to the crises. The crises are, of course, dramatic moments that you can't skip. And you can't get a sense from these books as to how all of this is interconnected in, in the valleys, right? In the crags, down there.

• 3:26:29Speaker 01

  Like, what, what are the mechanisms that are connecting these peaks together? And that's how I tried to write the big history, the New Roman Empire, is to tell the story by casting light in those darker places. That is, to show how especially institutions and ideologies sort of tie, you know, people's lives together, that is, tie people to institutions and to the broader history that surrounds them. So that the reader can get a sense, when I'm, when I'm recounting specific events, or either of, you know, greatness, or of success, or of failure, that they can understand roughly why these things are happening, right? Look, there's no perfect answer.

• 3:27:14Speaker 01

  A short book will just not tell you these things. A long book, well, is a long book.

• 3:27:19Lex Fridman?

  Well, in some sense, I mean, this, in this, even in this very conversation, I think we did a pretty good job of looking at the valleys, at the structure, at the institutions. And that gives you a sense of the whole underpinnings. And so it's, it's beautiful. It's a beautiful way to see history, especially for societies that have lasted as long as, as the, as the East Roman Empire has.

• 3:27:38Speaker 01

  But it did take us a few hours.

• 3:27:39Lex Fridman?

  Yes.

• 3:27:40Speaker 01

  Yes. You're right. But it, it requires that you, that you actually spend some time to look in there. Yeah.

• 3:27:47Lex Fridman?

  What's, what's a few hours among friends?

• 3:27:48Speaker 01

  No, no, no, that's, I, I agree.

• 3:27:50Lex Fridman?

  So zooming out and asking once again, the old, we're getting a little, close to last call at a bar, and ask you the big question. We asked it before about the collapse of the West Roman Empire. When did the decline of the East Roman Empire begin for you?

• 3:28:16Lex Fridman?

  Throughout this loops, when, if you were to predict, would you be able to say where this is going to be over? And what led to that decline and the collapse? So of course, the collapse is in, finally, in 1453 A.D.

• 3:28:37Speaker 01

  Right. That's actually a very good question. In other words, not looking at all of the previous crises that caused loss of territory, like you lose Egypt, you lose Syria, you lose Palestine, you lose Eastern Asia Minor, right? But at what point could you say there's no coming back from this? Right? I would say early 14th century, somewhere between 1300 and 1350, the sources of resilience begin to dry up. And you have a number of setbacks. They lose Asia Minor to the Turks by 1300, roughly, which means that you can now no

• 3:29:19Speaker 01

  longer draw upon the two wings, as it were, the European side and the Asian side, which they could always do. They're confined to Europe. And then you have a series of civil wars, you have the Serbian expansion, and you have the Black Death. And they never recover from that. In 1300, you think of this, you look at it, and you think, that's a tiny little Balkan state. Okay, it goes from Constantinople to the Adriatic in this sort of ribbon, right? This corridor that just stretches across the Balkans. And yet, it's not that much smaller than England and has about as much, if not more,

• 3:30:04Speaker 01

  revenue, because they're still able to raise cash because taxes. Right? So the emperor's still able to pull in a lot of gold. And his territory is not, you know, completely insignificant. It's not what the Roman Empire used to be. But I don't think that it's completely lost. Then they have some civil wars. Then one rebel makes a deal with the Serbs, surrenders half that territory. Okay, after that, game over. What's surprising is it takes the Turks that long. 1453, that's another century, right? It didn't need to be. It looks like they might have had it wrapped up like 50 years after, you know, like by 1400. But then accidental events happened.

• 3:30:49Speaker 01

  This is Timur, Tamerlane, comes from Central Asia, trounces the Turks, breaks up their empire. So they go into a cycle of rebuilding. And so that's why it takes another 50 years. Anyway, but I'd say by the 1340s, game over.

• 3:31:05Lex Fridman?

  And so why did it collapse? What are the things in the ground? When you zoom out, the thing that ate away at the, I like this term, sources of resilience.

• 3:31:19Speaker 01

  Oh, foreign invasions. There's no question.

• 3:31:21Lex Fridman?

  It's just invasion.

• 3:31:22Speaker 01

  It's foreign invasions, those which they could not cope with. They coped with lots of them. But, you know, all it takes is to lose to one and you lose some part of your territory. And if you keep losing enough, you won't have anything to fall back on. And that's what happens.

• 3:31:42Lex Fridman?

  So really, you know, if there's no significant external invasions, the East Roman Empire, the fundamentals, the taxation system, the way the policies were developed, the way the politics was done, the way the representation was done, all of that, this empire could have lasted for another thousand years.

• 3:32:07Speaker 01

  Absolutely. I'm absolutely convinced of this because you never see movements to split away. That is, there's no separatist movements, at least not on the part of any Roman provincials. There's one separatist movement, which is Bulgaria. We mentioned Bulgaria was conquered, right, in 1018. There's a couple of independentist movements, rebellions. Eventually one succeeds in 1185. So just under two centuries. So Bulgaria is the only part of this empire that actively seeks to break away and does so. But for the rest of the 1,200 years, you don't find provincials wanting to leave this system. However much they complain about the taxes,

• 3:32:51Speaker 01

  they don't want to leave and they make no move to do so. You also never have a moment when the center loses its ability to tax its territories. Right? You don't have like widespread peasant uprisings or provincial, right? Agricultural rebellions or these kinds of things, which happens in every other one of these empires. They also never decide to partition it. The Franks partitioned theirs, right? Like after Charlemagne. No, there are no like Roman warlords that try to carve out a piece of the territory for themselves and rule it independent. Nope, that doesn't happen either. So if you're looking at the kinds of factors that cause states to fail, fragment,

• 3:33:35Speaker 01

  you know, become ungovernable, these never happen.

• 3:33:40Lex Fridman?

  This is so incredible. This is truly incredible. In the history of human civilization, just an incredible study of what human societies can form. So what are the whys? Why? Why? Why was it so stable?

• 3:33:57Speaker 01

  Well, now, look, there are other stable, like, for example, the British monarchy. That's been around for quite a while, right? States like Portugal, Japan, they have one thing in common. They're all tucked away at the edges. Like they're off, they're little islands or whatever. They're not like, right? We're talking about a society that was right in the middle of one of the main corridors of empire building and new religions in the world. This is the most dangerous neighborhood, right? That you can possibly live in. So no wonder it didn't survive. Like, it would have been extraordinary if it had. But absent those forces,

• 3:34:40Speaker 01

  I don't see any forces of internal decomposition that would have imperiled it significantly.

• 3:34:49Lex Fridman?

  So what, I mean, we've talked about a lot of it, but what, just to like return to it, why was there no internal?

• 3:34:59Lex Fridman?

  Sources of decomposition. Like, why, why did it work so well? Why did the people feel represented? Yes, they, by the way, you talked about how they complain about the taxes, which is one of the signs of a healthy society that we, it's like complaining about the weather. The fact that you complain about the taxes actually means that you're happy with the taxes, kind of intuitively, or it's not too bad.

• 3:35:19Speaker 01

  Yeah.

• 3:35:19Lex Fridman?

  Just complaining is part of the system. Anyway, but why? Why, why, why did it work so well? Why did everybody get along?

• 3:35:26Speaker 01

  Oh, no, no, no.

• 3:35:27Lex Fridman?

  Feel represented? No, not get along.

• 3:35:28Speaker 01

  Yeah.

• 3:35:29Lex Fridman?

  Not in a, in a silly way. I mean, sufficiently to where they wouldn't, warlords wouldn't rise and break apart the system.

• 3:35:37Speaker 01

  Yeah.

• 3:35:37Lex Fridman?

  Or if there was those kinds of forces, they would come back together.

• 3:35:41Speaker 01

  Yeah.

• 3:35:41Lex Fridman?

  Like, why is this such a great self-healing system?

• 3:35:44Speaker 01

  So you're exactly right. So sufficient is the key word. We don't want to idealize this, right? These aren't like, they're not just dancing in the streets, holding hands and, right? It's so, even when it comes to the tax system, they are complaining all the time. Of course, they're doing so because they know that complaining gets you things. There's no disincentive to complaining. You might not get what you want, or you might get it, but you know, no harm will come to you. So they're complaining all the time. They have all of these civil wars. They're like, okay. So I, I think I would give you a two-part answer, sort of really quickly, as to why this held together so well. First, is that an extraordinary effort was made by the authorities

• 3:36:28Speaker 01

  to persuade their subjects that they were ruling on their behalf? And I think, for the most part, actually tended to do so. And the second is that it had a very tightly unified identity as Roman and as Orthodox. In other words, for the most, most time, they knew that they were surrounded by enemies who were not those things. And they did not want to live under the power of non-Romans and non-Christian people. And so those two factors combined, I think, gave everybody reason to hold it together. The alternatives were worse.

• 3:37:06Lex Fridman?

  Yeah, I mean, that's a really brilliant summary. And I think we should mention that both the rhetoric and the action are important. I think you've articulated that rhetoric is really powerful, like stating over and over and over.

• 3:37:20Lex Fridman?

  That you represent the people, that you're you're acting on behalf of the people and doing the action, but it's not enough to actually do the action. You would think that's all Machiavelli says is the only thing that matters. Then no, the rhetoric actually has a lot of power.

• 3:37:33Speaker 01

  Yes.

• 3:37:33Lex Fridman?

  Because it is a uniting idea, an ideal that propagates through time and it pacifies you, it makes you, puts you at peace.

• 3:37:41Speaker 01

  Yeah.

• 3:37:41Lex Fridman?

  Rhetoric is important.

• 3:37:43Speaker 01

  I'll give you an example. As a academic administrator, right? I mean, I was a chair of department for years and years. There's a difference between a dean who says, um, sorry, bad budget situation, we're just going to have to cut your programs, on the one hand, and a dean who says, I am fully on board with what you're trying to accomplish with these programs. I am a defender of the humanities. Unfortunately, we have this budget situation and we're going to have to cut some of the programs, but I assure you, the moment I'm

• 3:38:23Speaker 01

  in this with you together, the moment we find the funds, we will restore them. Those two, just rhetorical strategies, they're aiming at the same practical outcome, will produce very different levels of compliance, right, and consensus.

• 3:38:40Lex Fridman?

  And I should say that there's subtlety there. The best rhetoric in that context, and maybe in the East Roman Empire, is you also have to believe it.

• 3:38:50Speaker 01

  Yes, it has to be credible. You can't just say it and then not do it.

• 3:38:53Lex Fridman?

  But one of the things I've learned about humans, just having, doing this little podcast, is that it, people could, like, the best way to say a thing, a powerful thing, is to really believe it. And so like, this clearly, one of the things that made the Roman Empire work is Doing the action is the best way to make the rhetoric powerful and effective.

• 3:39:19Speaker 01

  Yeah. This is sort of what Aristotle says about tyrants. In the Politics, Aristotle is giving essentially advice to tyrants on how to protect themselves, because tyrants are usually hated and are killed in coups, right? And he says, so how, you know, essentially, how do you manage to secure yourself when you're a tyrant? Well, you know, you can start by maybe, you know, obeying the laws or making sure that your subjects obey the laws and, you know, maybe work for the interests of your subjects. Essentially, he's telling them to kind of become benevolent kings. Just, and the best way to persuade your subjects that you're legitimate benevolent kings is to be that.

• 3:40:00Lex Fridman?

  Yeah.

• 3:40:00Speaker 01

  Yeah.

• 3:40:01Lex Fridman?

  So what, from all of this, from this 2,200-year history of the Roman Empire, what lessons can we draw for modern times? Now, we're sitting in America, this young empire. I know we're not calling it an empire, but you know.

• 3:40:19Speaker 01

  Lots of people are calling it an empire. I thought it was sort of taboo. Yeah, in the 20th century, it was like, ah, is America an empire or not? But like, I think since the Iraq War, like, since 2003, I, I've seen at least very casual uses of America and empire in the same, you know, sentence without any kind of hand wringing.

• 3:40:39Lex Fridman?

  Is it ever called that in an academic setting?

• 3:40:42Speaker 01

  Yes.

• 3:40:42Lex Fridman?

  I mean, technically, I guess you could say, given, given the expanse of the military bases and, and the military might and the way that represents itself in the geopolitical context.

• 3:40:55Speaker 01

  There are books published all the time that unironically discuss America as an empire in various ways. Yeah, no.

• 3:41:02Lex Fridman?

  By the way, both positive and negative. So when you're saying a positive thing about America, calling it an empire, and when you're saying to criticize America, you call it an empire. Yeah, you're right.

• 3:41:11Speaker 01

  Yeah, I mean, most academic books aren't trying to do like, either. They're just trying to analyze a situation.

• 3:41:16Lex Fridman?

  Yeah.

• 3:41:16Speaker 01

  Yeah.

• 3:41:17Lex Fridman?

  What lessons about, about representing the people, about flourishing, about stability can we draw?

• 3:41:27Speaker 01

  I will say that.

• 3:41:30Speaker 01

  Just drawing on what we were talking about a moment ago, that investing in institutions that work for the majority of your subjects, even if indirectly, like they have to pay a cost for them, but you have to explain to them why they're paying that cost, is to the benefit of the ruling classes as well. Because you're, ideally, you're thinking about long-term success and not just your own short-term, you know, gain. And I think that's what the society tends to do well. You know, the Romans generally, you know, how they built roads for the centuries and the millennia? They built institutions too. You know, one of the institutions they built was like the Christian church.

• 3:42:13Speaker 01

  Like, they build things to last. And I think that's a, that's a good lesson beyond even the roads. I think institutions that explain, you know, to people why they exist is, uh, yeah, I think we could, we could use some of that.

• 3:42:30Lex Fridman?

  And also, the first point you made about the East Roman Empire. I think you've said that US foreign policy sometimes has a, quite a large gap between the rhetoric and the, in modern times, the rhetoric and the action. And so this, to Mackey Valley's point, that we want to maybe narrow that gap for a successful empire, for a successful nation, the rhetoric has to match the action.

• 3:42:56Speaker 01

  Yes.

• 3:42:56Lex Fridman?

  It doesn't quite for some of the foreign policy engagements in the world.

• 3:43:03Speaker 01

  So, in the context of the society I study, let's say the army is the single largest expense, is doing pretty much what the emperors say that it's doing, which is protecting its subjects. That's actually what it's doing most of the time. Not all the time. So, for example, emperors will sometimes take the armies out on a raid or an expedition, you know, crack some skulls, gather some plunder, come back, and this is done to glorify the emperor. Like, yeah, yeah, yeah, this, this does happen. But for the most part, they're doing that, not much else. And actually, in pre-modern contexts, it's very difficult to operate like, you know, shadow foreign policies and things like this. Like, it's just not part of the, it's not, not, not in the cards.

• 3:43:48Speaker 01

  But America in particular has such a history of proclaiming the loftiest goals. It just, sometimes just, you know, breathtakingly implausible.

• 3:44:04Lex Fridman?

  Plus, the incredible engineering behind the military industrial complex. So, America is very good at creating the flamethrowers.

• 3:44:13Speaker 01

  Yes.

• 3:44:13Lex Fridman?

  The, the technologies of war. And so, the lofty goals combined with just a lot of profit that could be made on the technologies of war creates a very difficult situation to navigate where the gap naturally widens.

• 3:44:27Speaker 01

  I don't think most of the world even believes, you know, what American leaders say their goals are, especially when it comes to, like, war. Like, spreading democracy, really? I, I remember when they were trying to convince me, us, that the, the invasion of Afghanistan was a feminist war.

• 3:44:50Lex Fridman?

  Oh, that was the thing, huh?

• 3:44:51Speaker 01

  Oh, yes. They were to liberate the women from the burkas or whatever. And the, the news was just flooded with like, how terrible women have it in Afghanistan. It's like, you're really trying to persuade me that that's why you're sending armed for, like, anyway.

• 3:45:06Lex Fridman?

  I think there's a lot, a lot of wake-up calls about the war in Afghanistan and Iraq, where people realized that there is that gap between the rhetoric and the action. And, I mean, that's how, because of a lot of people waking up to that, they, they create.

• 3:45:23Lex Fridman?

  Pressure on the government to close the gap. And that's how we kind of navigate this complicated world. But it's a costly one. I mean, these were extremely costly wars.

• 3:45:32Speaker 01

  Yes.

• 3:45:32Lex Fridman?

  On every front, on every measure.

• 3:45:35Speaker 01

  Yep, but the same lesson was learned in like the Vietnam War. And that was such a disaster that essentially they had to switch to abandon the conscript army, switch to a professional army. And like, it took them so long to be able to like wage, you know, these empire wars again because of the sheer damage that the Vietnam War did to the credibility of the military leadership in the country. Right? This never happens in like, this doesn't happen in Constantinople. I can lose a, you can be criticized for losing a war. That's, that's one thing, right? But that you're using the army to do some like, you know.

• 3:46:16Lex Fridman?

  Some of this does have to do with the functioning of how democracy works, the temporary nature of the leaderships and that they're very short sighted because of the nature of the, of the elected position of the executive. I mean, that's what we're trying to figure out as a human civilization, how to do this in this particular case, the democracy thing.

• 3:46:40Speaker 01

  There's no right answer. And by the way, I don't want to be ruled by kings or monarchs or emperors either. So it's like, I wouldn't necessarily support that. I'm not advocating here for anything. I'm just trying to explain, but you're exactly right. You know, we want democracy. We want leaders whom we can eject every four or five years, which includes sometimes their, their, you know, teams of experts and policy designers and whatever. And that comes at a cost too.

• 3:47:07Lex Fridman?

  So you said that, you know, the Roman Empire, maybe ancient Greece, maybe the societies before that, and now societies after that, the society we live in are very different. And so applying the lessons of history, you have to be careful doing so. But are there things that are the same?

• 3:47:29Lex Fridman?

  With us humans, so of everything you've studied across hundreds of years and centuries, are there aspects of human nature that kind of persist?

• 3:47:39Speaker 01

  So, look, intellectually, I have gone through periods when, like when I was a grad student, it was, you know, this was kind of when post-modernism, what we might call loosely, was kind of alive and well and not, had not yet been kicked in the pants. It was very common to find colleagues who did not believe that there was such a thing as, let's say, human nature. In other words, that, let's say, the parameters of human psychology are, you know, yes, there's considerable variation, but they're within a certain set of, you know, you know, norms. Like, it's not, we're not going to behave like,

• 3:48:20Speaker 01

  like different species. And, and that they did not believe that there was such a thing. In other words, that all of human history is essentially a series of incommensurate slices of difference, right? That you just couldn't go from one to the next. And I think it's a very problematic view for all kinds of reasons. Like, how, how small do you slice these slices? I mean, and, no, I'm with Lucidities on this one, who says that, you know, more or less, human beings are going to, more or less, they're, they're going to be after, right? They love and they hate and they have ambitions and they're incompetent. And, you know, you find the whole range of, you know, the whole gamut of diversity, pretty much

• 3:49:02Speaker 01

  in every, any group of about 20 or 30 people, you're going to find the same kinds of types. Now, culture then comes in and, you know, tweaks things in all kinds of weird ways. And that's, as a historian, what I'd like to study. I like just how the, the, the culture will modify, will set the dials, right? But that the dials go from one to 10, most people, it's like, yeah, yeah, yeah, I think so.

• 3:49:25Lex Fridman?

  But every once in a while, there'll be a few. A few folks who come along, whether it's Steve Jobs with a turtleneck or some guy with a weird mustache or with a funny hat. And those can turn the tides of history.

• 3:49:40Speaker 01

  I think so, occasionally, yes.

• 3:49:42Lex Fridman?

  But they're just ultra skilled at the right time, at the right moment.

• 3:49:47Speaker 01

  Oh, I believe that, too. Oh, yeah. In other words, I don't, I also don't think that, that cultural systems or ideologies are so effectively totalitarian that they sort of colonize the mind of every person. And so everyone in a culture is just like a clone. No, you encounter this sometimes in, in historical scholarship. And no, I think people can sometimes just think for themselves or they can think outside the box and they can do all kinds of things. And, and I always want to keep my mind open to that possibility when I'm encountering historical agents.

• 3:50:19Lex Fridman?

  So just because you've seen this grand history, I apologize for the ridiculous question. But if we look at the entirety of Earth and we fast forward a million years from now.

• 3:50:33Lex Fridman?

  And the, and the history of life on Earth is written. Do you think we're at the very beginning of human history? Or is, are we in the middle or are we close to the end?

• 3:50:48Speaker 01

  A million years from now. I mean, I can't project or predict anything like a year from now. And I've, I've become actually increasingly skeptical that I can do so at least. However, so I don't know about beginning, middle and end.

  It's easier to think in terms of like, like numbered phases, like significantly different phases of human history. And I would say we're probably in the third. I think there've only been three phases. The first one being sort of hunter gatherer period, which that lasted for the majority of human history so far, right? Then there's the agricultural revolution, basically. And this is when you start to produce surpluses that create more complex societies. And we're now living through a technological, first industrial, now.

• 3:51:40Lex Fridman?

  You can throw it all in the same bucket, industrial, technological.

• 3:51:42Speaker 01

  Industrial technological, which is modifying the parameters of what it is that human beings can do and possibly be. And who knows where this will go, but I see these as very distinct in many ways. It's all human beings.

• 3:51:57Lex Fridman?

  Yeah, it's all humans.

• 3:51:58Speaker 01

  Very different contexts.

• 3:51:59Lex Fridman?

  They're almost modifying themselves. So the question is, is there a fourth? Is there going to be?

• 3:52:06Speaker 01

  I'm pretty sure there will be.

• 3:52:07Lex Fridman?

  And what does that look like? And is it, when they look back at the third, would they still see us as the same as them? Or would it be something completely different?

• 3:52:21Speaker 01

  Oh, no, I, I mean, we look back at the, you know, Romans or the Greeks or like any period in history and we're like, yeah, no, I, I see what you're doing there. You're doing it with the, you know, the technological capabilities that you had at that time, you're doing it with the materials that you had, but I see what you're doing. Yeah, you've got, you've got families and you've got armies and you've got, you know, you bury your dead and you, you know.

• 3:52:44Lex Fridman?

  But now we're increasingly actually having the tools and technology to modify, like deeply modify what it means to be human. Genetic engineering, brain-computer interfaces. As we understand the brain more, we can modify things, expand completely. Plus, artificial intelligence, it can expand the, the, the, the knowledge base and the intelligence of the human mind. Unless we figure out the human mind is actually incredibly special to the degree words, at least with the tools we have this century, we cannot accomplish, we cannot achieve the level of intelligence that generally tells that humans have.

• 3:53:27Lex Fridman?

  Or one of these we might figure out in stage four of this long history is that the thing that makes humans special is not intelligence, it's not any of the things we kind of value each other by, it's actually consciousness. And consciousness is the thing that is very difficult to engineer.

• 3:53:46Speaker 01

  Yeah.

• 3:53:46Lex Fridman?

  And so that's the common thing from the hunter gatherers to before the industrial revolution and after is we're still the same. We still feel like something to be alive. And that's maybe an important component of what makes us fall in love with each other or fear each other or suffer, suffer and all the full range of the human condition, the human experience. Maybe even technology cannot, cannot replicate that, cannot modify that. Maybe that's what we learn. Or very possibly we destroy this whole thing. Cause now for the first time in human history, we have the tools, unfortunately, to destroy everything.

• 3:54:29Speaker 01

  This is all very eloquent. I mean, after so many hours of my rambling about the medieval Roman Empire, you're, you're, yeah, I'm, I'm impressed.

• 3:54:38Lex Fridman?

  Okay. What gives you hope about this whole thing? About the future of human civilization?

• 3:54:44Speaker 01

  Look, there are a lot of challenges, right? That, that we, that we face and we talk about them a lot.

• 3:54:53Speaker 01

  As a historian, I see other periods that were far, far more difficult when people could have far more easily have given up hope and sometimes did.

• 3:55:06Speaker 01

  But I, I don't think we're in one of those, like there, there's some major issues, like the uncertain future of technologies, what they might do, exactly what you were talking about. I think they're solvable problems to a certain degree. Like if we can rein in some elites, a lot of these problems can be fixed. And that's not like a super difficult, I mean, it's difficult, but it's not like impossible. Look, um, so I, I grew up during the Cold War. Let's just take the eighties, for example. And in the eighties, like there was a pervasive sense that nuclear war could happen at any time and just annihilate everything. And we lived under that. If you look at the popular culture of the eighties, it's like all like upbeat and cheerful and naive.

• 3:55:49Speaker 01

  And like, there was just no correlation. And then you move into the nineties and the Cold War is over and everyone's all depressed. The music gets all like whiny and like, what happened? There's just no correlation. Anyway, I just think that that's a pervasive sense of hopelessness or despair doesn't always match with, like, if you look at the situation objectively. I mean, yeah, it can be pretty bad.

• 3:56:20Speaker 01

  But there's so much that's happening that is good all the time.

• 3:56:25Lex Fridman?

  So I think this period of human history will be, because we've talked about the ups and downs of the Roman Empire. I think unquestionably, this period in history, the 20th, the late 20th century and the 21st century will be seen as the flourishing of humans. So if we actually just wake up,

• 3:56:46Speaker 01

  Yeah.

• 3:56:46Lex Fridman?

  it's like what everything around us, by most measures of human flourishing, we're doing pretty good.

• 3:56:54Speaker 01

  The amount of like sheer misery is probably objectively decreasing every year. Now, you know, we're also creating problems, yes. That will cause misery down the road. Yeah, yes. But overall, I don't see a reason to despair and not have hope.

• 3:57:12Lex Fridman?

  Yeah, we're doing OK.

• 3:57:14Speaker 01

  We can do better. Let's do better.

• 3:57:17Lex Fridman?

  That's let's do better. Well, Anthony, this was an incredible conversation. Thank you for all the amazing work you do and for the whirlwind journey through such a fascinating part of human history. This was fun. Thank you for talking today.

• 3:57:36Speaker 01

  It was a pleasure to be here and thank you for, not just for inviting me. I mean, this is probably the largest audience, you know, I've ever spoken to. But also just for giving my field and this civilization that I study, the opportunity to be seen and heard from more people. I think that's very important. You've done a real service here, so I want to thank you for that.

• 3:57:58Lex Fridman?

  Thank you.
