Kaskaskia is a village in Randolph County, Illinois. Having been inhabited by indigenous peoples, it was settled by France as part of the Illinois Country. It was named for the Kaskaskia people. Its population peaked at about 7,000 in the 18th century, when it was a regional center. During the American Revolutionary War, the town, which by then had become an administrative center for the British Province of Quebec, was taken by the Virginia militia during the Illinois campaign.
