Tecumseh's death led to the collapse of his confederacy; except in the southern Creek War, most of his followers did little more fighting. In the negotiations that ended the War of 1812, the British attempted to honor promises made to Tecumseh by insisting upon the creation of an Indian barrier state in the Old Northwest. The Americans refused and the matter was dropped. The Treaty of Ghent (1814) called for Indian lands to be restored to their 1811 boundaries, something the United States had no intention of doing. By the end of the 1830s, the U.S. government had compelled Shawnees still living in Ohio to sign removal treaties and move west of the Mississippi River.
