Hernán Cortés captured the strong Aztec Empire through a combination of strategic alliances, superior weaponry, and psychological tactics. He formed alliances with various indigenous groups who were enemies of the Aztecs, which bolstered his forces. Cortés also leveraged the element of surprise and utilized firearms and horses, which the Aztecs had never encountered. Additionally, the outbreak of smallpox weakened the Aztec population, further aiding Cortés in his conquest.
