Hernando Cortes (Cortez) (1485-1547), Spanish conquistador, attacking natives in Mexico. Cortes landed in Mexico in 1519. With a force of only some 600 men, he succeeded in overthrowing the empire of the Aztecs, a civilization numbering 5 million. He was able to achieve this partly due to the natives being terrified of the Europeans' horses and firearms, neither of which they had seen before. In addition, the Aztecs believed a prophecy that they would be visited by a light-skinned bearded god, the Quetzalcoatl, who had taught them agriculture and government in the past, and whose return they were to welcome with great ceremony. Cortes was able to exploit his resemblance to the Quetzalcoatl to great effect. (Photo by Ann Ronan Pictures/Print Collector/Getty Images)
