Answer:
A. they formed an alliance with the enemies of the Aztecs
Explanation:
The conquest of the Aztecs took place between 1519 and 1521 and was one of the episodes of the Spanish invasion and colonization of America. The great Aztec Empire had been built by Mesoamerican peoples from the fourteenth century. With their conquest, the Spanish began the colonization of the region that today corresponds to Mexico.
After a great defeat against the Aztecs in 1520, Cortes did not fully reorganize his forces until 1521, when he formed a gigantic army of thousands of Tlaxcaltec warriors (enemies of the Aztecs). In addition, he built numerous vessels to surround Tenochtitlán (the Aztec capital was on an island in the middle of a large lake that no longer exists). Reports told of violent fighting taking place in the streets of Tenochtitlán.
The result of the siege of Tenochtitlán was the Spanish victory. The new emperor, whose name was Cuahtemoc, was taken prisoner, and from there the Spaniards moved on to conquer the other smaller cities controlled by the Aztecs. With the conquest of this people, the Spanish established in the region the Vice Kingdom of New Spain, which was initially administered by Cortes himself.
