Summary

Written by a model from the transcript; not yet reviewed.

This episode explores the improbable chain of historical events linking a 1784 shipwreck in the Gulf of Mexico to the Louisiana Purchase, which doubled the size of the United States. The hosts recount how a fisherman named Jerry Murphy accidentally dredged up silver coins from the sunken Spanish ship El Casador in 1993, prompting a look back at why the vessel was carrying 19 tons of currency to New Orleans. When the silver went down, King Carlos of Spain faced a financial drain that made the distant Louisiana colony seem less worthwhile, eventually leading Spain to return the territory to France. The hosts explain how a successful slave revolt in Haiti then destroyed Napoleon's economic plans for the region, causing him to sell the entire Louisiana Territory to Thomas Jefferson for fifteen million dollars.
