Europeans were able to take over the Americas in the 15th, 16th, and 17th centuries due to a combination of factors. These included technological advantages such as guns and ships, the spread of diseases to which Native Americans had no immunity, and the political and economic motivations of the European powers. Additionally, the Native Americans were often divided and unable to unite against the Europeans, allowing them to be easily conquered.
