History
Calhoun County was settled by Americans during the very early 19th century, and officially organized in 1825. It was named for Vice President John C. Calhoun. The southern side of the county, covered in thick forest, was untouched until the population began to expand in the late 1840s with the arrival of German immigrants. Land was cleared for farming, exporting lumber, and constructing spacious log barns, typically in size, which were a "trademark of successful German farmers."

The territory was originally settled by indigenous people who occupied the resource-rich river valleys near waterways. The remains of their occupation have provided some of the most valuable archaeological information in the country. The county's archaeological record chronicles more than 10,000 years of continuous human occupation by Native Americans.
In 1680, French explorer René-Robert Cavelier, Sieur de La Salle recorded in his diary historic Native American raids by the Iroquois against the Illinois tribes along the Illinois River. La Salle recounts the aftermath of a massacre of the Illinois by the Iroquois in South Calhoun County writing, "As the French drew near to the mouth of the Illinois, they saw a meadow to the right, and, on the farthest verge, several human figures erect, yet motionless. They landed and cautiously examined the place. The long grass was trampled down and all around were strewn the relics of the hideous orgies which formed the ordinary sequel of an Iroquois victory. The figures they had seen were the half consumed bodies of women still bound to the stakes where they had been tortured. Other sights there were, too revolting for record. All the remains were of women and children; the men, it seems, had fled, and left them to their fate. The French descended the river and soon came to the mouth." The massacre is noted as taking place in the last week of November 1680, about a mile above the site of the Deer Plain Ferry which is no longer in operation, at a place now known as Marshall's Landing. Many skulls, parts of skeletons, and weapons have still been found near this spot by farmers during plowing.

Politics
For two generations following the Civil War, Calhoun County was typical of the German counties on the Illinois side of the Mississippi River in being heavily Democratic as it had opposed the “Yankee” American Civil War. However, many citizens of Calhoun County enlisted in military on the side of Union during the war. The people of Calhoun generally were not sympathetic to the Confederate cause, as there are accounts of Calhoun citizens harassing Confederate sympathizers and Calhoun was often the target of Confederate desperados who would steal horses, burn barns, and generally terrorize the locals. Only when German-Americans were offended at Woodrow Wilson's policies towards Germany did the county vote Republican for the first time in 1920, and it narrowly repeated that in the GOP landslides of 1924 and 1928. The county did turn strongly Republican due again to opposition to war involvement in 1940, and remained Republican-leaning for three decades. Between 1970 and 2008 Calhoun turned Democratic once more – George Bush senior in 1992 won a smaller proportion of the vote than Alf Landon in 1936 or William Howard Taft in 1912. The county leaned heavily Republican during the 2010s, so that Joe Biden’s 2020 vote percentage is the worst ever by a Democrat. Despite Donald Trump defeating Hillary Clinton by almost 40 points in 2016, Calhoun County concurrently voted Democratic in the Senate race, narrowly supporting Tammy Duckworth over Mark Kirk.
As of February 2025, the county is one of 7 that voted to join the state of Indiana.
