County of union

History & Founding

Union County, Arkansas, traces its origins to 1870 when it was carved from parts of Calhoun, Ouachita, and Howard counties. The name itself is a tribute to the Union soldiers of the Civil War, a deliberate choice reflecting the Reconstruction era's political climate and a desire to signify loyalty to the United States. Prior to its establishment, the area was inhabited by Quapaw Indians, and later saw settlement by Choctaw and Chickasaw tribes as part of forced relocation efforts. During the late 19th century, the discovery of oil spurred significant growth, transforming the region from a largely agricultural landscape to an industrial hub. A fascinating anecdote from this period tells of a local farmer, William H. Bass, who famously struck oil while attempting to drill a water well in 1920, unknowingly initiating the South Arkansas Oil Boom. This event dramatically reshaped the county’s fortunes and attracted a wave of prospectors and entrepreneurs. Union County played a vital role in Arkansas’s development, particularly in the state’s emergence as an oil-producing region.
