what was the major factor in native american displacement
History of Native Americans in the United States In the 19th century, the incessant westward expansion of the United States incrementally compelled large numbers of Native Americans to resettle further west, often by force, almost always reluctantly. Native Americans believed this forced relocation illegal, given the Hopewell Treaty of 1785. Under President Andrew Jackson, United States Congress passed the Indian Removal Act of 1830, which authorized the President to conduct treaties to exchange Native American land east of the Mississippi River for lands west of the river.
American Indian Wars When the British made peace with the Americans in the Treaty of Paris (1783), they ceded a vast amount of Native American territory (without the consent of the indigenous peoples) to the United States. The United States treated the Native Americans who had fought with the British as enemy allies, a conquered people who had lost their land. The federal government of the United States was eager to expand, and the national government did so by purchasing Native American land in treaties and through warfare.
