The Spanish Conquistadors were adventurers during the Medieval times who sought fame and riches by exploring and conquering lands in the Americas following the Reconquest of Spain from the Muslims. Key figures like Hernando Cortes and Francisco Pizarro led expeditions to conquer the Aztec and Inca empires, respectively, using deception, violence, and technology advantages to defeat forces many times their size and claim the lands and wealth for Spain. The Conquistadors were motivated by monetary gain, expanding Catholicism and the Spanish empire.
