Rockford is Illinois's fifth-most populous city with 148,655 residents in 2020, located in Winnebago and Ogle counties in far northern Illinois on the Rock River and serving as the county seat of Winnebago County. Originally settled as Midway in the mid-1830s for its location equidistant between Lake Michigan and the Mississippi River, Rockford was renamed in 1837 and officially chartered as a city in 1852, earning the nickname "Forest City" in 1853. The city became an industrial powerhouse in the 19th and early 20th centuries, particularly for heavy machinery and furniture production following inventor John Henry Manny's arrival in 1853 to manufacture mechanical reapers, but experienced significant decline typical of Rust Belt cities in the late 20th century. Since the late 1990s, Rockford has pursued economic diversification through automotive and healthcare industries alongside downtown revitalization and tourism development. The city is home to cultural landmarks including the Anderson Japanese Gardens, Coronado Theatre, Burpee Museum of Natural History, and Rockford University (founded as Rockford Female Seminary in 1847), and has contributed notable musical acts including Cheap Trick. Joliet is a city located 40 miles southwest of Chicago in Will and Kendall counties, serving as the county seat of Will County, with a 2020 census population of 150,362, making it Illinois's third-most populous city. Originally settled in 1852 as a steel mill town on the Des Plaines River, Joliet became known as the first major city outside Chicago on U.S. Route 66, which was completed through the city in 1926 and features the first-ever Dairy Queen location. The city's industrial heritage includes the Joliet Iron and Steel Works, once the second-largest steel mill in the United States, which operated from 1869 to 1936 and is now preserved on the National Register of Historic Places. Joliet is home to Old Joliet Prison, the state's largest correctional facility when completed in 1858 and constructed from local limestone, which gained prominence through films including the 1980 movie The Blues Brothers before closing in 2002 and reopening for tours in 2018. Named after French explorer Louis Jolliet who paddled the Des Plaines River in 1673, the city was reincorporated in 1852 under its first mayor, Cornelius Covenhoven Van Horne, after residents changed the spelling from "Juliet" to "Joliet" in 1845. DeKalb is a city of 40,290 residents located in DeKalb County, Illinois, approximately 65 miles west of Chicago and 30 miles southeast of Rockford. Named after Revolutionary War hero Baron Johann de Kalb, the city was founded in 1856 and became a pioneering center for barbed wire manufacturing after Joseph Glidden patented double-strand barbed wire there in 1874, with companies like American Steel and Wire eventually merging into United States Steel. DeKalb also played a leading role in commercial hybrid corn development through the DeKalb Agricultural Association, which beginning in 1934 produced seed varieties that dominated American farming until the mid-1970s before being acquired by Bayer in 2017. Today, Northern Illinois University, founded in 1895, serves as the city's largest employer, though agricultural and service industries remain significant economic sectors. The city sits along the South Branch Kishwaukee River in northern Illinois and experiences a humid continental climate with four distinct seasons.
