The 1970s see a new reassessment of federal policies that grants Native nations the right to self-determination. Several important acts shift control over programs - in education, health services, policing, and other areas - to tribal governments. The federal government recognizes that it is bound by treaties. The courts affirm that treaties have to be honored.
Some of these developments are beginning to be undone by the late 1980s. The American Indian Religious Freedom Act, for example, is rendered ineffective by the Supreme Court.
