Civil rights organization founded in 1968, originally to help urban American Indians displaced by government programs. It later broadened its efforts to include demands for economic independence, autonomy over tribal areas, restoration of illegally seized lands, and protection of Indian legal rights and traditional culture. Some of its protest activities involved violence and were highly publicized (see Wounded Knee). Internal strife and the imprisonment of some leaders led to the disbanding of its national leadership in 1978, though local groups have continued to function.
