Answer:The aztec empire
Step-by-step explanation:
Hernan Cortez overthrew the Aztec empire by convincing the Aztec people that he and his crew were gods and they got the Aztec king to promote that story; he also allied with enemy tribes of the Aztec empire who played a major role in the upcoming war. Then Hernan Cortez's men witnessed a sacrifice in Tenochtitlan and proceeded to start killing people which caused the Spanish to be kicked out of Tenochtitlan. After they were kicked out the Aztecs met them in open battle expecting to win but lost and Tenochtitlan was put under siege by the Spanish. Most of Tenochtitlan's population died of disease which caused them to surrender.
