History of Will County

Will County was formed on January 12, 1836, out of Cook and Iroquois Counties. It was named after Conrad Will, a politician and businessman involved in salt production in southern Illinois. Will was a member of the first Illinois Constitutional Convention and a member of the Illinois legislature until his death in 1835. The county originally included the part of Kankakee County, Illinois, north of the Kankakee River. It lost that area when Kankakee County was organized in 1852. Since then its boundaries have not changed. 36 locations in Will County are on the National Register of Historic Places.
