This was a treaty between the U.S. and the Lakota Indians. The two parties came to an agreement to give the Lakota people the Black Hills and hunting rights in South Dakota, Wyoming, and Montana. However, migrant workers looking for gold had crossed the Lakota borders, in violation of the treaty. Indians had assaulted these workers, also in violation of the treaty. War would soon follow. The U.S. government then seized the Black Hills land in 1877. The dispute over the land between the Lakota Indians and the U.S. can still be found in courts today.
