History of DuPage County

Prior to European-American settlement, the area that is now DuPage County was inhabited by the Potawatomi people. By 1800, the Potawatomi had established 4 major villages along local rivers within the county, and had a network of trails crisscrossing the area. The first European-American settlers arrived in what is now DuPage County in 1832, and the Potawatomi population was forced out of the region only one year later after ceding their land in the Treaty of Chicago. DuPage County was officially formed on February 9, 1839, out of Cook County. The county took its name from the DuPage River, which was, in turn, named after a French fur trapper, DuPage. The first written history to address the name, the 1882 History of DuPage County, Illinois, by Rufus Blanchard, relates: The DuPage River had, from time immemorial, been a stream well known.
