Thomas Jefferson sent diplomats to Paris to buy New Orleans and came back with roughly 800,000 square miles. This episode digs into the real mechanics of the 1803 Louisiana Purchase, a deal driven by a blocked port, a revolution in Haiti, and Napoleon’s need for cash to fight Britain.

We explore why the loss of Saint-Domingue made Louisiana useless to Napoleon, how Jefferson set aside his strict constructionism, the narrow House vote on funding, and how Baring and Hope financed the deal through bonds. Then we examine what the United States actually bought, the expansion of slavery, the Missouri Compromise, and the cost of later land cessions from Native nations.

• Why the right of deposit at New Orleans was vital to western farmers
• How the Haitian Revolution and yellow fever wrecked Napoleon’s plans
• How James Madison justified the purchase through the treaty power
• Why a British bank helped finance a deal that funded Britain’s enemy
• Why historians argue the U.S. bought only the preemptive right to the land
