What are a few reasons why the Aztec civilization declined?
Answer The main reason for the fall of the Aztec civilization was the arrival of the Spanish Conquistadors. The Spanish had superior weapons and military tactics. They quickly took control of the entire empire, in part by playing various tribes against each other and also with military might. Spread of smallpox also destroyed much of the population, thus making the Spaniards’ job easier. I hope this helps!
