DeKalb County is part of the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area.

History

DeKalb County was formed on 4 March 1837, [3] out of Kane County, Illinois. The County was named for Johann de Kalb, [4] a German (Bavarian) hero of the American Revolutionary War. DeKalb County's area is approximately 632.7 square miles, located 63 miles west of Chicago. There are 19 townships in the county with the county seat at Sycamore.

Between 1834 and 1837, white men began to settle in DeKalb County along the streams and wooded areas because of the fertile soil, wild game, and food and water opportunities. Major growth stemmed from the introduction of the railroad which brought easier methods of transportation and opportunities for industrial growth. Early industries based in DeKalb County included Sandwich Mfg. Co, Marsh Harvester Co, Barbed Wire, and Gurler Bros Pure Milk Co.

The county is noted for agriculture. In 1852, the DeKalb Agricultural Society produced the county's first Agricultural Fair, in Sycamore. Eventually farmers, businessmen, bankers and newspapermen organized to become the DeKalb County Soil Improvement Association, which later was split into DeKalb County Farm Bureau and DeKalb Agricultural Association (DEKALB AgResearch, Inc., Monsanto). DeKalb County is credited with being the birthplace of the Farm Bureau movement. DeKalb County is also the 2nd largest hog producing county in Illinois and the 66th largest in the nation.

Education has played an important role in the area with Northern Illinois University located in DeKalb and Kishwaukee Community College located in Malta. A major fair has been held each year since 1887 at the Sandwich Fairgrounds in Sandwich.

Pronunciation

Unlike similarly spelled locations, such as DeKalb County, Georgia, DeKalb denizens from Illinois pronounce the county name /dɪˈkælb/ di-KALB, with an L sound, as in German.

Politics

As part of Northern Illinois, DeKalb County was a stronghold for the Free Soil Party in its early elections – being among nine Illinois counties to support Martin Van Buren in 1848 – and became overwhelmingly Republican for the century following that party's formation. The only time it did not back the official GOP nominee between 1856 and 1988 was in 1912 when the Republican Party was mortally divided and Progressive Theodore Roosevelt won almost half the county's vote. Republican candidate Alf Landon, who lost 46 of 48 states in 1936, won DeKalb County by double digits, whilst even Barry Goldwater – renowned for his antagonism towards the establishment – won by seven percent despite losing sixteen percent of the vote compared to Richard Nixon in 1960.

Beginning in 1992, DeKalb County has shown a strong trend towards the Democratic Party owing to the growth of its powerfully Democratic student population. In that year's election George McGovern, who was to lose all but 130 counties nationwide, managed to exceed his nationwide vote percentage in this county that had not voted Democratic since giving a plurality to Franklin Pierce in 1852. In 1980, Illinois native John B. Anderson won over fifteen percent of the county's vote and this was to shift towards the Democratic Party in subsequent elections. In 1992 and 1996, Bill Clinton became the first Democrat to carry the county in 140 years, and in 2008 another Illinois son, Barack Obama, became the first Democrat to win an absolute majority since Van Buren in the county's first-ever Presidential election of 1840. Obama repeated this in 2012, but economic concerns in the rust belt caused a sizeable swing away from Hillary Clinton in 2016, although she still narrowly won the county.
