As non-Indians moved westward, pressures were exerted upon the Indian land base. The federal government consequently evolved a policy of restricting the tribes to specified reservations. This goal was typically accomplished by treaty, exacted with varying degrees of persuasion and coercion, in which the tribe ceded much of the land it occupied to the United States and reserved a smaller portion to itself. On other occasions, the tribe was moved entirely away from the lands it was occupying to a distant reservation. (William C. Canby, Jr. American Indian Law in a Nutshell series)
