COUNTY FORMATION
Located in the southern portion of Illinois known locally as "Little Egypt," Union County was created on January 2, 1818, the same year Illinois became a state. The original boundries were carved from Johnson County. In 1819, a portion was lost to form Alexander County, reducing Union County to its current borders.
Union county was named in honor of a joint revival meeting of the Baptists and Dunkards, called a "union meeting." The county seal depicts the leaders of these two groups shaking hands.
The county seat is Jonesboro.
