American Indian activism after 1945 was as much a part of the larger, global decolonization movement rooted in centuries of imperialism as it was a direct response to the ethos of civic nationalism and integration that had gained momentum in the United States following World War II. This ethos manifested itself in the disastrous federal policies of termination and relocation, which sought to end federal services to recognized Indian tribes and encourage Native people to leave reservations for cities. In response, tribal leaders from throughout Indian Country formed the National Congress of American Indians (NCAI) in 1944 to litigate and lobby for the collective well-being of Native peoples. The NCAI was the first intertribal organization to embrace the concepts of sovereignty, treaty rights, and cultural preservation—principles that continue to guide Native activists today. As American Indian activism grew increasingly militant in the late 1960s and 1970s, civil disobedience, demonstrations, and takeovers became the preferred tactics of “Red Power” organizations such as the National Indian Youth Council (NIYC), the Indians of All Tribes, and the American Indian Movement (AIM). At the same time, others established more focused efforts that employed less confrontational methods. For example, the Native American Rights Fund (NARF) served as a legal apparatus that represented Native nations, using the courts to protect treaty rights and expand sovereignty; the Council of Energy Resource Tribes (CERT) sought to secure greater returns on the mineral wealth found on tribal lands; and the American Indian Higher Education Consortium (AIHEC) brought Native educators together to work for greater self-determination and culturally rooted curricula in Indian schools. While the more militant of these organizations and efforts have withered, those that have exploited established channels have grown and flourished. Such efforts will no doubt continue into the unforeseeable future so long as the state of Native nations remains uncertain.
