DeKalb County was formed on March 4, 1837, out of Kane County, Illinois. The County was named in honor of Johann de Kalb, a German (Bavarian) hero of the American Revolutionary War. DeKalb County 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, early 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. Some of the notable industries based in DeKalb County were: Sandwich Manufacturing Company, Marsh Harvester Company, Barbed Wire, Gurler Brothers Pure Milk and many more.
The county has always been noted for agriculture. In 1852, the first Agricultural Fair was held in Sycamore, under the supervision of the DeKalb Agricultural Society. Eventually farmers, businessmen, bankers and newspapermen organized to become the DeKalb County Soil Improvement Association. In later years the DeKalb County Soil Improvement Association would split into two and become 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.

DeKalb County is divided into nineteen townships:
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. 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 1972, 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 Illinoian, 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, but she still narrowly won the county.
