The earliest known Euro-American settler in what is now Carthage was William Walton (1760–1816), who arrived in the late 1780s. Circa 1800, Walton directed the construction of the Walton Road (Cumberland Turnpike), an early stagecoach route connecting the Knoxville area with Middle Tennessee. The road, which roughly paralleled what is now U.S. 70, would prove influential in the early settlement of the Cumberland region. Walton operated a ferry and tavern along the road, around which a small community developed. In 1804, Walton's community was chosen as the county seat of the newly formed Smith County after a heated election, and the town of Carthage was laid out shortly thereafter.
Carthage's situation at the confluence of the Cumberland and Caney Fork rivers made it an important shipping and steamboat port throughout the first half of the 19th century. During the Civil War Carthage became an important post in the Eastern Highland Rim area of Tennessee. Carthage was selected as part of the route Confederate General Braxton Bragg marched the Army of Mississippi through on his Confederate Heartland Offensive into Kentucky. Later on March 6, 1863, Union Brigadier General George Crook established a Union outpost in Carthage to serve as a base from clearing out the considerable Confederate guerrilla activity that was active from east Tennessee through middle Tennessee. As for Carthage's prominence as a river port on the Cumberland River, the emergence of railroads later in the century made steamboat and river travel largely obsolete, and the area's industrial focus shifted to South Carthage and Gordonsville.
