On the Pine Ridge Reservation in South Dakota, some 200 Sioux Native Americans, led by members of the American Indian Movement (AIM), occupy Wounded Knee, the site of the infamous 1890 massacre of 300 Sioux by the U.S. Seventh Cavalry. The AIM members, some of them armed, took 11 residents of the historic Oglala Sioux settlement hostage as local authorities and federal agents descended on the reservation.

AIM was founded in 1968 by Russell Means, Dennis Banks, and other Native leaders as a militant political and civil rights organization. From November 1969 to June 1971, AIM members occupied Alcatraz Island off San Francisco, saying they had the right to it under a treaty provision granting them unused federal land. In November 1972, AIM members briefly occupied the Bureau of Indian Affairs in Washington, D.C., to protest programs controlling reservation development. Then, in early 1973, AIM prepared for its dramatic occupation of Wounded Knee. In addition to its historical significance, Wounded Knee was one of the poorest communities in the United States and shared with the other Pine Ridge settlements some of the country’s lowest rates of life expectancy.
