The Black Hills land claim is an ongoing land dispute between Native Americans from the Sioux Nation and the United States government over the Black Hills mountain range in the US states of South Dakota and Wyoming. The land in question was pledged to the Sioux Nation in the Fort Laramie Treaty of April 29, 1868, but a few years later illegally seized and the treaty nullified in the Indian Appropriations Bill of 1876 without the tribe's consent. That bill "denied the Sioux all further appropriation and treaty-guaranteed annuities" until they gave up the Black Hills. A Supreme Court case was ruled in favor of the Sioux in 1980. The Sioux have outstanding issues with the ruling and have not collected the funds. As of 2011, the award was worth over $1 billion.
