Clark County is a county located in the southeastern part of U.S. state of Illinois, along the Indiana state line. As of the 2010 census, the population was 16,335.[1] Its county seat is Marshall.[2] The county was named for George Rogers Clark, an officer who served in the American Revolution.[3]

History

Clark County was formed in 1819 out of Crawford County. At the time of its formation, Clark County included about a third of Illinois, and extended as far north as the present state of Wisconsin. In 1821 the northern part of Clark County became part of the newly created Pike County on January 31, and the newly created Fayette County took the western part of Clark County on February 14. Edgar County was created from the northern part of Clark County on January 3, 1823. The creation of Coles County occupied additional land from western Clark County, effective December 25, 1830.[4] The boundaries of Clark County have been unchanged since.

Clark County was named for George Rogers Clark[5] (older brother of William Clark of the Lewis and Clark Expedition), an officer of the army of Virginia that captured the Northwest Territory from the British during the Revolutionary War.

The county seat was located in Darwin Township in 1823. A county-wide referendum was held In 1839 to determine whether Auburn or Marshall would be designated as the new seat. Marshall won the election and has remained the county seat since then.[6]

Geography

According to the U.S. Census Bureau, the county has a total area of 505 square miles (1,310 km2), of which 501 square miles (1,300 km2) is land and 3.4 square miles (8.8 km2) (0.7%) is water.[7] Part of the county's eastern border is defined by the Wabash River. The North Fork of the Embarras River and Hurricane Creek are the main streams in western Clark County. Other than the Wabash River, Big Creek is the major stream in the eastern part of the county.[8]

Politics

In its early days, Clark County favored the Democratic Party, not supporting a Republican presidential candidate until Theodore Roosevelt’s 1904 landslide. Since 1920, it has been a strongly Republican county: the last Democrat to win a majority being Lyndon Johnson in 1964, and only Bill Clinton by plurality in 1992 has won the county since.
