Hernan Cortes led an expedition from Cuba to Mexico in 1519, landing in present-day Veracruz. He gained alliances with native civilizations like the Tlaxcala who were enemies of the Aztecs. Cortes continued gaining allies as he traveled to Tenochtitlan, the Aztec capital, where emperor Moctezuma II greeted him. However, Cortes had his men massacre Aztec nobles. The Aztecs drove the Spanish out but Cortes returned with greater forces and finally retook Tenochtitlan in 1521, destroying the Aztec empire.
