What are the factors of why the Europeans were able to get the early civilizations in the Americas to basically bend at their own will?

The Europeans were able to dominate early civilizations in the Americas due to a combination of advanced military technology, such as firearms and steel weapons, which gave them a significant advantage in combat. Additionally, they exploited existing rivalries among indigenous groups, forming alliances that weakened the resistance against them. The spread of diseases like smallpox, to which Native Americans had no immunity, decimated populations and undermined social structures, further facilitating European conquest. Lastly, the allure of European goods and the promise of wealth often swayed some indigenous leaders to cooperate with colonizers.
