History

Richland County was established on February 24, 1841. Its formation came during a period of territorial organization and settlement in Illinois as communities subdivided larger counties into smaller administrative units. The county's name reflects the region's productive soils and early emphasis on farming.

Geography and economy

The county's landscape is typical of central and southern Illinois: a mix of cropland, pasture, small woodlots, and town centers. Agriculture is a major economic driver, accompanied by local manufacturing, retail, and services that support rural life. Transportation links connect towns to regional markets, and community institutions such as schools and hospitals center life in Olney and nearby villages.
