History

Settlement in the area began during westward expansion after the Black Hawk War era when migrants moved along the Fox River Trail and the Illinois and Michigan Canal corridors.

Industrial growth in the late 19th and early 20th centuries paralleled firms in Rockford, Illinois and manufacturing clusters associated with Sears, Roebuck and Company distribution networks. Post‑World War II suburbanization echoed trends in the Sunbelt migration and the rise of Interstate Highway System infrastructure, with commercial developments influenced by regional actors such as Walmart and Target Corporation expanding along transport arteries.
