History
Formed in 1852 from Hempstead County, Lafayette County, Ouachita County and Union County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Columbia County was created from Hempstead, Lafayette, Ouachita, and Union counties. The county was named after Christopher Columbus. It gained territory from Union in 1858 and from Nevada in 1873, but lost land to the creation of Nevada in 1871 and to Lafayette in 1901.
