History. Soon after the end of the Civil War (1868), Escambia County was formed from parts of Conecuh and Baldwin Counties by an Act of Legislature of Alabama. The Act was introduced by Mr. Mark Lyons, the grandfather of Senator Lister Hill. Mr. Lyons was a merchant and timber buyer who resided in Pollard. In the Act creating the county, Pollard was designated as the Seat of Justice, and remained the County Seat until 1883. It was then moved to Brewton. The first courthouse was built in 1901.
