History

The future state of Indiana was first regulated by passage of the Northwest Ordinance in 1787. In 1790 the Territory was divided into two counties, with Knox covering much of present-day Indiana. In 1810, a portion of Knox was partitioned to create Wayne County; in 1811 a portion further south was partitioned to create Franklin. The area between those two counties was partitioned in 1818 to create Fayette; by the 1820s the eastern part of Fayette County was populated sufficiently to warrant separate representation. Thus on 5 January 1821 the state legislature authorized the creation of Union County, with areas ceded from Wayne County, Fayette County and Franklin County. The organization of the new county’s governing structure began on 1 February 1821.

It was so named because it united 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 community 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.

Geography

Union County lies on the east side of Indiana; its east border abuts the state of Ohio. Its low rolling hills have now been cleared of timber, although drainage areas are still largely brush-filled. The area is devoted to agricultural or recreational uses. The highest point on the terrain (1,140 feet/350 meters ASL) is a rise near the county’s north border, 1.0 mile (1.6 km) ENE from Witts Station.

Silver Creek flows southwestward through the northeastern part of the county, discharging into Whitewater Lake. The East Fork of Whitewater River flows southward through the upper western part of the county, discharging into Brookville Lake. The lower part of the county is drained by Dubois Creek, flowing westward into Brookville Lake.

According to the 2010 census, the county has a total area of 165.18 square miles (427.8 km), of which 161.22 square miles (417.6 km) (or 97.60%) is land and 3.95 square miles (10.2 km) (or 2.39%) is water.
