What were 3 reasons why the Spanish defeated the Aztecs?

The Spanish defeated the Aztecs primarily due to superior military technology, including firearms and steel weapons, which gave them a significant advantage in battles. Additionally, they exploited existing divisions among the indigenous tribes, forming alliances that bolstered their forces against the Aztecs. Lastly, the introduction of diseases such as smallpox decimated the Aztec population, weakening their ability to resist Spanish conquest.
