History

Formed in 1839 from Ouachita Parish

An old deed may name a county that no longer exists, or a boundary that has since moved.

Union Parish was created from Ouachita Parish in 1839. It lost territory to the creation of Jackson Parish in 1845, then exchanged land with Jackson and Ouachita parishes in 1846. In 1867 it gained territory from Claiborne Parish, and in 1873 it lost territory to the creation of Lincoln Parish.
