De Soto played a significant role in Pizarro's Conquest of the Inca Empire, which began in 1532. He served as Pizarro's second-in-command and was instrumental in the capture of the Inca capital of Cuzco in 1533. He later led a series of expeditions into the interior of the empire, searching for gold and silver. He died in 1542 while leading an expedition to Florida.
