One notable Native American on the frontier was Chief Sitting Bull. He was a Hunkpapa Lakota Sioux chief who led his people in battles against the United States Army during the Sioux Wars in the late 19th century. Sitting Bull is known for his role in the Battle of Little Bighorn, where he and his forces defeated General George Armstrong Custer and his troops. Despite his resistance to U.S. expansion, Sitting Bull eventually surrendered and lived on a reservation until his death in 1890.
