The expeditions of Conquistadors Francisco Pizarro and Hernán Cortés had in common their pursuit of wealth and territory in the Americas, driven by the desire to conquer indigenous empires. Both leaders successfully toppled powerful civilizations—Cortés defeated the Aztec Empire, while Pizarro conquered the Inca Empire.
