By 1881, Indian landholdings in the United States had plummeted to 156 million acres. By 1934, only about 50 million acres remained (an area the size of Idaho and Washington) as a result of the General Allotment Act* of 1887. During World War II, the government took 500,000 more acres for military use. Over one hundred tribes, bands, and Rancherias relinquished their lands under various acts of Congress during the termination era of the 1950s.
By 1955, the indigenous land base had shrunk to just 2.3 percent of its original size.
