Which of the following was NOT a factor in how 600 Spanish men conquered the Aztec Empire?

The assertion that the Spanish knew the terrain very well is accurate in that they were largely unfamiliar with the geographical landscape of the Aztec Empire, which was different from their own homeland. This unfamiliarity with the terrain actually put them at a disadvantage in many respects compared to the Aztecs, who had a deep understanding of their own land.

In contrast, the other factors were significant contributors to the Spanish conquest. The superior weaponry of the Spanish, including firearms and steel swords, provided a technological edge that the Aztecs could not match, especially since they primarily fought with weapons made of obsidian and wood. The internal conflicts within the Aztec Empire weakened their ability to unite against the invaders, which the Spanish exploited. Additionally, the alliances the Spanish formed with rival tribes, such as the Tlaxcalans, significantly bolstered their forces and provided vital knowledge as well as support in their military campaigns against the Aztecs. Thus, the combination of these factors substantially facilitated the Spanish conquest, while their lack of terrain knowledge stands out as a notable exception.
