Sitting Bull was a Hunkpapa Lakota chief and holy man. He was born around 1831 on the Grand River in present-day South Dakota. He became a warrior in a battle with the Crow at age 14, subsequently becoming renowned for his courage in fights with the U.S. Army.
In 1874, an expedition led by George Armstrong Custer confirmed the discovery of gold in the Black Hills, an area that had been declared off-limits to white settlement by the Fort Laramie Treaty of 1868. When efforts by the government to purchase the Black Hills failed, the Fort Laramie Treaty was abrogated. All Lakota not settled on reservations by January 31, 1876, would be considered hostile. Sitting Bull led his people in holding their ground.
