Will County, Illinois

History

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.

Government

Will County is governed by a 22-member county board elected from 11 districts. Each district elects two members. The county executive, county clerk, coroner, auditor, treasurer, recorder of deeds, state's attorney, and sheriff are all elected in a countywide vote. The current county executive is Jennifer Bertino-Tarrant, who took office in 2020.

Will County government has been housed in a succession of courthouses, the first being erected in 1837. The fourth courthouse was designed of reinforced concrete in the Brutalist style by Otto Stark of C.F. Murphy Associates and completed in 1969. Citing lack of space, inefficiency and high operating costs, the County Board chose to erect a new courthouse, which was designed by Wight & Co. and completed in 2020. Considerable controversy surrounded the disposition of the 1969 courthouse, with Landmarks Preservation Council of Illinois including the building on its “2022 Most Endangered Historic Places in Illinois”. After a number of votes and appeals, demolition was approved and the destruction of the building began on December 4, 2023.

Politics

Like most of the collar counties, Will County was once a Republican stronghold. It went Republican in all but three elections from 1892 to 1988. Since the 1990s, it has become a swing county. It voted for the national winner in every presidential election from 1980 to 2012, but Chicago-born Hillary Clinton won it along with the rest of the "collar counties" aside from McHenry in 2016.
