Kendall County, Illinois is a county in the U.S. state of Illinois located southwest of Chicago. It was formed in the early 19th century and named for a prominent jurist. The county seat is Yorkville, Illinois, and the county includes growing suburbs, historic towns, and portions of regional transportation corridors such as Interstate 80, Interstate 88, and U.S. Route 34.

History

Kendall County was created from parts of LaSalle County, Illinois, Putnam County, Illinois, and Will County, Illinois and named for Amos Kendall, a member of the Andrew Jackson administration and later an associate of Samuel F. B. Morse. Early settlement featured migrants from New England, New York (state), and Pennsylvania following the completion of the Erie Canal and influenced by the Black Hawk War aftermath. Towns such as Yorkville, Illinois, Oswego, Illinois, and Plano, Illinois developed along trade routes and waterways including the Fox River (Illinois–Wisconsin) and feeder streams. Railroads including lines by the Chicago, Burlington and Quincy Railroad and the Chicago and North Western Transportation Company spurred 19th-century growth and linked the county to Chicago, Illinois industry and markets. The county's 20th-century history intersected with national currents through ties to World War I, World War II, the Great Depression, and postwar suburbanization influenced by projects like the Federal-Aid Highway Act of 1956. Preservation efforts in places like the Yorkville Historic District and archaeological work connected to Mississippian culture sites reflect the county's layered past.

Geography

Protected areas and parks connect to regional systems managed in partnership with organizations such as the Illinois Department of Natural Resources and local conservation districts. Climate patterns follow a humid continental climate regime shared with Aurora, Illinois, Joliet, Illinois, and Naperville, Illinois, producing cold winters and warm summers that influence agricultural cycles of crops like corn and soybean, as seen across Kankakee County, Illinois and DeKalb County, Illinois.
