Option: Horses

Explanation:

Hernan Cortes was able to conquer the Aztec Empire in 1521 because of the superior firearms and cavalry. The Spanish had steel weapons, horses, and cannons, which was an advantage to defeat the larger Aztec army who were unknown to the Horses. Horses helped the Spaniards in wining further battles because of cavalry, which provided a deadly attack on the Aztecs people without getting any injured.
