7. Cortés and Moctezuma
A small group of conquistadors led by Cortés reached Mexico in 1519.
Moctezuma II, the Aztec leader, believed that Cortés was a god.
Moctezuma sent Cortés gifts, including gold. Cortés wanted more gold, so he went to Moctezuma.
Cortés took Moctezuma prisoner. The other Aztecs attacked Cortés and his men. The Spanish were driven out, but Moctezuma was killed.
Cortés returned with many Indian allies and in 1521 they defeated the Aztecs and ended their empire.

8. Causes of the Defeat of the Aztecs
Alliances The Spanish had made allies in the region who gave them supplies, information, and warriors.
Weapons The Spanish had better weapons than the Aztecs. They had cannons, armor, swords, and horses that the Aztecs did not have.
Geography The Spanish were able to cut off the capital city. The people had no food or water, so many Aztecs died of starvation.
