Sitting Bull , also nicknamed Slon-he or "Slow"; (c. 1831-December 15, 1890) was a Hunkpapa Lakota Sioux holy man who led his people as a tribal chief during years of resistance to United States government policies. Born near the Grand River in Dakota Territory, he was killed by Indian agency police on the Standing Rock Indian Reservation during an attempt to arrest him and prevent him from supporting the Ghost Dance movement. Sitting Bull's premonition of defeating the cavalry became reality. Seven months after the battle, Sitting Bull and his group left the United States to Wood Mountain, Saskatchewan, where he remained until 1881, at which time he surrendered to US forces. A small remnant of his band under Chief WanbliÃ‚Â decided to stay at Wood Mountain. After his return to the United States, he briefly toured as a performer in Buffalo Bill Cody's Wild West Show, earning $50 a week.
