What factors led to and enabled the conquest of the Aztecs and incas by the Spanish?

The conquest of the Aztecs and Incas by the Spanish was facilitated by several key factors. Firstly, the Spanish brought advanced military technology, including firearms and steel weapons, which gave them a significant advantage in combat. Additionally, the Spanish exploited existing rivalries and dissent among Indigenous groups, forming alliances that weakened the empires' cohesion. Lastly, the impact of European diseases, such as smallpox, devastated Indigenous populations, undermining their ability to resist conquest.
