Newnan was established as county seat of Coweta County (replacing the defunct town of Bullsboro) in 1828 and was named for North Carolinian General Daniel Newnan. It quickly became a prosperous magnet for lawyers, doctors, other professionals, and merchants. Much of Newnan's prosperity was due to its thriving cotton industry, which relied on slavery.Newnan was largely untouched by the Civil War due to its status as a hospital city (for Confederate troops), and as a result still features muchantebellum architecture. Celebrated architect Kennon Perry designed many of the town's 20th century homes. During the Atlanta Campaign, Confederate cavalry defeated Union forces at the nearby Battle of Brown's Mill.
