By the early 19th century, there were tensions among the Creek, with young men of the Upper Creek promoting a revival of religion and traditional culture, and the Lower Creek, more influenced by settlement and trade with European Americans in Georgia, becoming more assimilated. In addition, in 1811, the Shawnee chief Tecumseh of the upper Northwest appealed to the Creek to join his Western Confederacy to try to drive out and exterminate the European settlers west of the Appalachians.
