Treutlen County got its territory from Emanuel and Montgomery counties in 1917. Its land a wealth of wiregrass and pine forests, the region saw its earliest settlers arrive in 1784, historians speculate. The county bears the name of John Adam Treutlen who participated in the Provincial Congress of 1775 and served as the state's first official governor. While visiting Orangeburg, South Carolina, Treutlen was murdered, allegedly by Tories. Soperton, the county seat, is named for a prominent local citizen.
