 The passage of the Indian Civil Rights Act of 1968 (ICRA) was influential.ICRA guaranteed the application of much of the Bill of Rights in Indian Country, a guarantee which Native Americans on reservations had not enjoyed.The rise of activist groups in the 1960s, such as the American Indian Movement (AIM), and high-profile demonstrations such as the occupation of Alcatraz led by Native American activist Richard Oakes (activist), helped bring the issue of Native American rights to greater prominence in public policy.
