History

Union County was formed out of Johnson County, nearly a year before the Illinois Territory gained statehood.[3] It was named for 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.[4]

  • For its first year of existence, Union County included an area of unorganized territory temporarily attached to it.[5]
  • In 1819, the additional territory became Alexander County, reducing Union to its current borders.
