August 11, 1965

Named after Robert Caulk, who held the first patent to the land in 1860, the town of Caulksville of Logan County voted to receive official incorporation. Following the Civil War, more white settlers began to move into the area, prompting Caulk to build a post office in 1870. By 1891, Caulksville had two general stores, three grocery stores, a grist mill, a cotton gin, and a blacksmith shop. Population decline was exacerbated by the Great Depression, causing the closure of the post office. The town’s incorporation may have been to prevent annexation by the nearby town of Ratcliff (Logan County).
