The Indian Claims Commission was established in 1946 (abolished in 1978) to review "territorial claims by native peoples within the forty-eight contiguous states and, where these were found to be valid, to retire them through payment of appropriate compensation." Most of the claims dealt with the undervaluation of tribal lands in treaties of purchase and the failures of the United States government to abide by treaty provisions.
