Dallas, the county seat for Paulding County, incorporated on February 8, 1854. The city remembers George M. Dallas of Pennsylvania, who served as vice president for James Polk.
Built in 1892, the county courthouse is listed on the National Register of Historic Places. In and around Dallas, lie two other historic sites and monuments - Pickett's Mill and New Hope Church. The Pickett's Mill Battlefield State Historic site is said to be one of the best-preserved Civil War battlefields in the nation. The New Hope Church monument is the spot of a three-day battle during which Confederate troops fought to hold the line against Union troops heading toward Atlanta.
