In July 1519, Cortes and his men took over Veracruz and in mid-August continued on towards Tenochtitlan. They made alliances along the way with various native tribes who would help the Spaniards take over Cholula, the second largest city in Mexico.
Cortes was able to conquer the Aztec Empire of millions of people for several reasons of varying importance. The Aztec's cruel tribute system, Marina and Aguilar as translators, the Spanish military dominance, Cortes' Indian allies, the Quetzakoatl myth, and the smallpox epidemic all contributed in the Spanish success.
