Welcome to the Illinois State Historical Society The mission of the Illinois State Historical Society is to foster awareness understanding research preservation and recognition of history in Illinois. The Society was founded in 1899 to support the Illinois State Historical Library and to encourage research and writing on subjects of Illinois history. Though independent of the State of Illinois and the Historical Library since 1997 the Illinois State Historical Society continues to actively promote the study of Illinois history. The Society encourages everyone from university scholars to local historians to take an active part in Illinois history.
