Tanasi is first mentioned in early 18th-century documents as the base or destination of various English colonial traders and diplomats. Tanasi appears on multiple maps of the Overhill territory produced in the 1720s and 1730s, but Chota does not. This suggests that Chota may have been part of Tanasi, or may not have been considered a town before the 1740s. In the 1720s, the head man of Tanasi— known simply as the "Tanasi Warrior"— was the chief of the Overhill towns in what is now Tennessee, and the Middle and Valley towns in Western North Carolina. Chota does not appear in historical records until around 1745.
