Why were the aztecs conqured so easily?

The Aztecs were conquered relatively easily due to a combination of factors, including the arrival of Spanish conquistadors led by Hernán Cortés, who exploited existing rivalries among indigenous groups. Many tribes resented Aztec rule and allied with the Spanish, providing crucial support. Additionally, the introduction of European diseases, such as smallpox, decimated the Aztec population, weakening their defenses and social structure. The technological advantages of the Spanish, including firearms and horses, further facilitated their conquest.
