In what ways were the fall of the Inca and Aztec empires alike?

The fall of the Inca and Aztec empires were alike in several key ways, primarily due to the impact of European colonization, particularly by Spanish conquistadors. Both empires faced internal strife and weakened political structures before their conquests, which made them more vulnerable. Additionally, the introduction of European diseases decimated indigenous populations, significantly undermining their ability to resist. Lastly, the superior military technology and tactics of the Spanish forces played a crucial role in the rapid downfall of both empires.
