After Tecumseh's death in 1813, Tenskwatawa retained a small group of followers, but had no significant leadership position among the American Indians in the subsequent decade. In 1824, at the request of Lewis Cass, the governor of Michigan Territory, the aging Prophet returned to the United States from Canada to assist the federal government with its plans for the Shawnee removal west of the Mississippi River. Tenskwatawa hoped his involvement would allow him to regain some influence as a leader among the Shawnee.
