The treaty included articles intended to "ensure the civilization" of the Lakota; financial incentives for them to farm land and become competitive - and stipulations that minors should be provided with an "English education" at a "mission building". To this end the US government included in the treaty that white teachers, blacksmiths, a farmer, a miller, a carpenter, an engineer and a government agent should take up residence within the reservation.
Repeated violations of the otherwise exclusive rights to the land by gold prospectors led to the Black Hills War. The treaty explicitly described, "the permanent home of the Indians, which is not mineral land..." Migrant workers seeking gold had crossed the reservation borders, in violation of the treaty. Indians had assaulted migrant workers, in violation of the treaty. War ensued. The U.S. government seized the Black Hills land in 1877.
More than a century later, the Sioux nation won a victory in court. On June 30, 1980, in United States v. Sioux Nation of Indians, 448 U.S. 371, the United States Supreme Court upheld an award of $17.5 million for the market value of the land in 1877, along with 103 years worth of interest at 5 percent, for an additional $105 million.
