In this episode of pplpod, we explore the life of Hernando de Soto, the Spanish conquistador who helped topple the Inca Empire, grew wealthy beyond measure, and died chasing a second fortune in North America. Born in the late 1490s or early 1500s in impoverished Extremadura to a family of minor nobility, he grew up in the aftermath of the Reconquista, when ambitious young men had no war left at home. He sailed to Panama in 1514, honed his tactics in brutal campaigns in Central America, and became a skilled horseman who relied on seizing local chiefs to extort supplies.

The episode follows De Soto in Peru, where as a cavalry commander under Francisco Pizarro he took part in the capture of Atahualpa at Cajamarca, befriended the captive emperor, and returned from a scouting mission to find him executed. His share of the plunder made him one of the richest men in the world, and he returned to Spain in 1536 with a noble marriage and entry into the Order of Santiago. Still hungry for his own empire, he won the governorship of Cuba and the right to colonize North America, landing in Florida in 1539 with about 620 men, horses, and pigs. Without a centralized empire to decapitate, he relied on a fragile chain of interpreters, including Juan Ortiz, and on harsh violence, including the Napituca massacre and the devastating Battle of Mabila in 1540. Rather than reach his supply ships, he marched inland, crossing the Mississippi in 1541. He died of fever in 1542, and his men sank his body in the river to hide his death from native peoples who believed he was immortal. About 311 survivors reached Mexico. The expedition found no gold, left feral pigs, and contributed to the collapse of Mississippian societies, leaving a legacy of ambition, violence, and irony.
