What made the spanish more powerful than the Aztecs?

The Spanish were more powerful than the Aztecs primarily due to their advanced military technology, including firearms, steel weapons, and armor, which gave them a significant advantage in combat. Additionally, the Spanish formed strategic alliances with various indigenous groups who were rivals of the Aztecs, further weakening Aztec resistance. The introduction of European diseases, such as smallpox, decimated the Aztec population, undermining their ability to fight back effectively. These factors combined to enable the Spanish to conquer the Aztec Empire swiftly.
