Clark County

Clark County is an administrative division in southeastern Illinois that encompasses land shaped by river systems, particularly the Wabash River and the North Fork of the Embarras River. The terrain is generally flat and dominated by farmland, with Marshall serving as the county seat.

The county was established in 1819 and named after George Rogers Clark, an officer during the American Revolution. The region was originally part of a much larger territory that stretched farther north before it was divided into smaller districts.

The community revolves around farming and local traditions that show up in regular gatherings and county fairs. People across generations participate in these events and maintain their connections to one another.

Most government offices are located in Marshall, where you can find administrative services. You should check ahead to see which offices are accessible locally, as not all services are available everywhere.

The county originally stretched across a vast territory that extended all the way to present-day Wisconsin. This enormous area was gradually divided into separate counties over time to make administration easier.
