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.
War of 1812 American expansion into the Northwest Territory was being obstructed by various Indian tribes since the end of the Revolution, who were supplied and encouraged by the British. Americans on the western frontier demanded that interference be stopped.[42] There is dispute, however, over whether or not the American desire to annex Canada brought on the war. Several historians believe that the capture of Canada was intended only as a means to secure a bargaining chip, which would then be used to force Britain to back down on the maritime issues. It would also cut off food supplies for Britain's West Indian colonies, and temporarily prevent the British from continuing to arm the Indians.[43][44] However, many historians believe that a desire to annex Canada was a cause of the war. This view was more prevalent before 1940, but remains widely held today.[45][46][47][48][49][43] Congressman Richard Mentor Johnson told Congress that the constant Indian atrocities along the Wabash River in Indiana were enabled by supplies from Canada and were proof that "the war has already commenced.Â ... I shall never die contented until I see England's expulsion from North America and her territories incorporated into the United States."[50]
