When gold was discovered in their treaty territory, the US sent in troops to remove them 1876. Under chiefs Crazy Horse and Sitting Bull they defeated General George Custer at Little Bighorn, Montana; as a result, Congress abrogated the Fort Laramie Treaty of 1868 (which had given the Sioux a large area in the Black Hills of Dakota). Gold, uranium, coal, oil, and natural gas have been found there since, and the Sioux pressed for and were awarded $160 million compensation 1980.
