Native Americans had not ended their resistance. In the early 19th century, the Shawnee leader Tecumseh gained renown for organizing his namesake confederacy to oppose American expansion in Native American lands. The resulting conflict came to be known as Tecumseh's War. The two principal adversaries in the conflict, chief Tecumseh and American politician William Henry Harrison, had both been junior participants in the Battle of Fallen Timbers at the close of the Northwest Indian Wars in 1794. Tecumseh was not among the Native American signers of the Treaty of Greenville, which had ended the war, when the Shawnee and other Native Americans ceded much of their historic territory in present-day Ohio to the United States. However, many Indian leaders in the region accepted the Greenville terms, and for the next ten years pan-tribal resistance to American hegemony faded.
