History

Prior to European-American settlement, the area that is now DuPage County was inhabited by the
Potawatomi The Potawatomi (), also spelled Pottawatomi and Pottawatomie (among many variations), are a Native American tribe of the Great Plains, upper Mississippi River, and western Great Lakes region. They traditionally speak the Potawatomi language, ...
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 Cook County is the most populous county in the U.S. state of Illinois and the second-most-populous county in the United States, after Los Angeles County, California. More than 40 percent of all residents of Illinois live within Cook County. ...

, 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. It took its name from a French trader who settled on this stream below the fork previous to 1800. Hon. H. W. Blodgett, of Waukegan, informs the writer that J. B. Beaubien had often spoken to him of the old Frenchman, Du Page, whose station was on the bank of the river, down toward its mouth, and stated that the river took its name from him. The county name must have the same origin. Col Gurden S. Hubbard, who came into the country in 1818, informs the writer that the name DuPage, as applied to the river then, was universally known, but the trader for whom it was named lived there before his time. Mr. Beaubien says it is pronounced Du Pazhe (having the sound of ah, and that the P should be capitalized). This was in reply to Mr. Blodgett's inquiry of him concerning the matter.
The first white settler in DuPage County was Bailey Hobson who, with Lewis Stewart, built a house in 1831 for the Hobson family at a site about south of present-day downtown Naperville. Hobson later built a mill to serve surrounding farmers. Today, the Hobson house still stands on Hobson Road in Naperville, and the location of the mill is commemorated with a millstone and monument in today's Pioneer Park.

Government

DuPage County is governed by a County Board whose duties include managing county funds and business, levying taxes, and appropriating funds. The County Board exercises powers not assigned to other elected officials or other boards. The county is divided into six districts. Each district elects three members to the County Board in staggered two-year and four-year terms. The Chairman of the County Board is the chief executive officer of DuPage County, and is elected countywide every four years. DuPage County is part of Regional Office of Education #19 which is coterminous with the county's corporate boundaries. As of December 2022, the DuPage County Board is controlled by the Democratic Party by an 11 to 7 margin.


Politics

DuPage County was historically a stronghold of the Republican Party, and a classic bastion of suburban conservatism. In recent years, DuPage County has joined other suburban counties outside large U.S. cities trending Democratic in presidential election years since the 1990s. The county also leans Democratic in state and local politics. In the 2018 Illinois gubernatorial election, J. B. Pritzker became the first Democratic candidate for the governorship to win the county in nearly 100 years. DuPage County voters backed Pritzker in his 2022 re-election bid by a large margin.

Local politics

Republicans historically controlled local politics in DuPage County from the nineteenth century until modern times. During the twentieth century, Democrats only held countywide office twice. In 1934 William Robinson was elected Circuit Clerk and Arthur Hellyer was elected Treasurer. That year also saw the first ever Democratic majority county board and only such majority that century. Robinson and Hellyer each served one term; Robinson lost his bid for a full term in 1936 and Hellyer left the Treasurer's office to make a failed bid for probate judge in 1938. In 2018, as part of a larger suburban realignment, Democratic candidate Jean Kaczmarek won the election for County Clerk and Daniel Hebreard won the President of the Forest Preserve District of DuPage County. During that same period Democrats were sporadically elected to the county board and township government. In 1972, Don Carroll was elected to the County Board. In the Democratic wave of 1974, Jane Spirgel, Mary Eleanor Wall, and Elaine Libovicz were elected. All four were from the northeastern portion of DuPage, which at that time was the most Democratic region of the county. Eventually, Republicans regained all seats on the board when Jane Spirgel ran for

with Adlai Stevenson III under the Solidarity Party banner. In 2000, Linda J. Bourke Hilbert was elected. Like her 1970s counterparts, she was from the northeastern portion of the county. During the 2008 Democratic wave, three Democrats were elected to the board. After the initial Obama wave, Republicans reasserted themselves on the board and by 2017 Democrats held only one of the eighteen board seats. In the 2018 general election, Democrats won seven seats as well as the offices of County Clerk and Forest Preserve District President. In 1973, a slate of Democrats took eight of nine offices in Addison Township. This feat would not be replicated until 2017 when Democratic candidates won a majority of offices in Naperville and Lisle townships. Between these two victories, Democrats only held two township offices. Mark Starkovich served as York Township Supervisor from 1989 to 1993 and Martin McManamon has served as Wayne Township Highway Commissioner since 2013. In 2020, Democrats won control of the DuPage County Board, expanding on their 2018 lead. In 2022, Democrats expanded their majority in the County Board to 11 seats out of 18. Concurrently, Democrat Deb Conroy was elected as the chairman of the County Board.
