It includes numerous counties such as Cook County, Illinois, DuPage County, Illinois, Lake County, Illinois, Will County, Illinois, Kane County, Illinois, McHenry County, Illinois, Lake County, Indiana, and Kenosha County, Wisconsin. The area forms a major hub linking Great Lakes, the Mississippi River watershed, and national transport corridors like Interstate 90 and Interstate 94.
Geography and Extent
The metropolitan region occupies shores of Lake Michigan and extends inland across the Chicago Portage corridor, encompassing subregions like the North Shore (Chicago) and South Side, Chicago.

The 19th century brought events including the Illinois and Michigan Canal construction, the incorporation of City of Chicago and the transformative Great Chicago Fire. Industrial expansion tied to railroads—Chicago and North Western Railway, Chicago, Burlington and Quincy Railroad, Illinois Central Railroad—and the rise of firms like Pullman Company shaped labor conflicts such as the Pullman Strike and political movements including the Haymarket affair.
