Union County was formed in 1821. It was so named because it is
the product of a union of parts of Fayette, Franklin and Wayne
counties. The first settlers were from Laurens District, South
Carolina. John Templeton was the first settler to enter land at
the Cincinnati land office in what would become Harmony
Township, Union County Indiana. The first county seat was
Brownsville, a small town located on the East Fork of the
Whitewater River. The seat was moved in 1824 to Liberty, a
central location. The primary industry of Union County was and
is farming.
