In Feb., 1973, about 200 supporters, mostly Sioux, of the American Indian Movement seized control of the hamlet of Wounded Knee, S.Dak., demanding U.S. Senate investigations of Native American conditions. The occupation lasted 71 days, during which about 300 persons were arrested by federal agents. In 1979 the Sioux were awarded $105 million for the taking of their lands, resolving a legal action begun in 1923. Today they constitute one of the largest Native American groups, living mainly on reservations in Minnesota, Nebraska, North Dakota, South Dakota, and Montana; the Pine Ridge Indian Reservation in South Dakota is the second largest in the United States. Many are engaged in farming and ranching, including the raising of bison. The Shakopee Mdewakanton Sioux have a large casino on their reservation in Minnesota, but Oglala efforts to establish one at impoverished Pine Ridge have met with only partial success. Indian Country Today, a successful Native American newspaper, was started at Pine Ridge in 1981; it is now based in Rapid City, S.Dak. In 1990 there were more than 100,000 Sioux in the United States and more than 10,000 in Canada.
