Clark County is located in Southeastern Illinois. It was originally part of the Northwest territory. The first pioneer settlement was York, on the Wabash (Ouabache) River, before 1816. The present county was formed out of Crawford County in 1819, just a short time after Illinois became a state. At that time, the northern border of Clark County ran all the way to what would become Wisconsin. The County was named for George Rogers Clark, whose fame came mainly from his exploits on the Illinois frontier during the Revolutionary War. The first settlers came from Virginia, Ohio and Kentucky. Many were veteran soldiers of the War of 1812. Settlement increased after the construction of the National Road through the county. Clark County's first County Seat was at Aurora, on the Wabash River. The County Seat was moved to Darwin in 1823 when the good citizens of Aurora realized that the River could flood higher than they could build. In 1839, a county-wide election was held to decide on a new County Seat. The contenders were Marshall, and Auburn. The tempers were high as the voting day drew near and the tension grew. In spite of Auburn changing it's name to Clark Center, Marshall won the day and has been the County Seat of Clark County ever since.
As reported by the Census Bureau, the county has a total area of 505 square miles (1,308 km2), of which 502 square miles (1,299 km2) is land and 3 square miles (9 km2) (0.67%) is water.
