From the late 1940s through the 1960s, the federal government considered an Indian termination policy, to end the special relationship of tribes. Retreating from the emphasis of self-government of Indian tribes, Congress passed a series of laws to enable the government to end its trust relationships with native tribes. On 13 August 1946, it passed the Indian Claims Commission Act of 1946, Pub. L. No. 79-726, ch. 959. Its purpose was to settle for all time any outstanding grievances or claims the tribes might have against the U.S. for treaty breaches (which were numerous), unauthorized taking of land, dishonorable or unfair dealings, or inadequate compensation on land purchases or annuity payments. Claims had to be filed within a five-year period.
