In the years after the American Revolution, the Shawnee were the most prominent residents of west central Ohio, growing in numbers and permanency after the 1794 Treaty of Greenville. By 1817, the United States had created the Hog Creek Reservation for the local Shawnee, covering portions of what would become Allen and Auglaize counties, and including part of present-day Lima.
The creation of the Shawnee reservation freed other lands in the area for settlement, and in February 1820, the Ohio legislature formally established Allen County. In 1831 the Shawnee were forced to surrender all their land in the area to the United States and relocated to Kansas, opening all of Allen County to settlement. The Ohio legislature mandated that a county seat be established and "Lima" was the result.
