History and heritage
Randolph County is one of Illinois's older counties, formed in the late 18th century during the territorial era. Its long history reflects French colonial settlement, early American frontier development and the changing course of the Mississippi River. Several historic sites and museums in the county interpret French fortifications, frontier settlements and early state government activity.
Economy and culture
Agriculture remains a central economic activity, supplemented by local manufacturing, services and river-related commerce. Chester celebrates local heritage—most notably as the hometown of E. C. Segar, creator of the Popeye character—and hosts cultural attractions and festivals. Tourism tied to historic sites and outdoor recreation on the river and in county parks contributes to the local economy.
