The Treaty of Fort Laramie (1868) was an agreement between the United States government and several Native American tribes, including the Lakota Sioux, Cheyenne, and Arapaho. The treaty aimed to establish peace and define territorial boundaries, particularly in the Black Hills region of present-day South Dakota. In exchange for recognizing tribal lands, the U.S. promised to protect these areas from settlers and provide annual payments. However, the treaty was violated when gold was discovered in the Black Hills, leading to increased white settlement and conflict. The U.S. government ultimately failed to uphold its commitments, resulting in further tensions and wars with the tribes involved.
