Lat/Long: 39.3333, -87.8000
The Illinois General Assembly created Clark County in 1819 from Crawford County. Later that year, commissioners appointed for the purpose chose a site for the county seat and named it Aurora. In 1823, county residents successfully petitioned the legislature to move the county seat to different site, which they named Darwin. In 1834 and 1836, Clark County citizens petitioned the General Assembly to relocate the county seat from Darwin. In May 1837, voters decided to relocate the county seat, and in August, chose Marshall over Auburn as the permanent seat of justice for Clark County. County offices moved to Marshall in 1838. Originally comprising about one-fourth of the state, Clark County was reduced to its current size by 1831.
