Soperton, incorporated as a town December 17, 1902, is the county seat and the only incorporated town in Treutlen County. The town honors Benjamin Franklin Soper, a construction engineer with the Macon, Dublin and Savannah Railroad.
Soperton is known as the "Million Pines City" because landowner James Fowler planted more than 7 million pine seedlings on thousands of acres of county land. Pine by-products are now an important part of the local economy.
