Map - Calhoun County, Illinois (Calhoun County)

Calhoun County is a county in the U.S. state of Illinois. As of the 2010 census, the population was 5,089, making it Illinois’ third-least populous county. Its county seat and biggest community is Hardin, with a population of 801. Its smallest incorporated community is Hamburg, with a population of 99. Calhoun County is at the tip of the peninsula formed by the courses of the Mississippi and Illinois rivers above their confluence and is almost completely surrounded by water. Calhoun County is sparsely populated; it has just five municipalities, all of them villages.

Calhoun County is part of the Metro-East portion of the St. Louis, MO-IL Metropolitan Statistical Area.

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, in addition to the Calhoun family that was prominent in the area at the time. 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 200 sqft 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.

The first European settler to make his home in what is now Calhoun County was a man only known today by his last name, O'Neal. He came in the year 1801 and settled in the south part of the county at Point Precinct at what has been called "Two Branches". Although his name might have one assume differently, O'Neal was a French trapper and had made his way there from Acadia. O'Neal lived in Point Precinct a number of years before any other European settlers came to that region, and when they did come he refused to mingle with them. He lived in a small cave which he had dug, and which was located about a quarter of a mile from the Mississippi River. He continued to live in this cave until his death in 1842, and after that he was referred to as "The Hermit" due to the fact that he would not visit the other settlers or allow them to come to his place. In 1850, Soloman Lammy, who then owned the farm upon which the cave was located.

The next settlers to come to the area were French trappers and people of mixed ancestry, who started a community about a mile above what was called the Deep Plain Ferry, on the Illinois River, in the southern part of the county. They remained until about 1815 when they were driven out by the very high water. Another French settlement was located at Cap au Gris (which means Cape of Grit or Grindstone). This place was located at the site of what was once the West Point Ferry, in Richwoods Precinct. The French settlers who lived here came sometime after 1800 and by the year 1811 there were 20 families, who had a small village on the bank of the river, and cultivated a common field of about 500 acres. The field was located on the level land about a mile from the site of their town. One writer said that these families were driven away by the Native Americans in 1814, but there is some doubt as to the accuracy of the statement as John Shaw who took part in battles with the natives in the region and was a community leader at the time does not mention in his writings any harm coming to the settlers at Cap au Gris.

As early pioneers continued to settle in Calhoun County there is evidence of troubled relations between the European settlers and the Native Americans. There are two known cases on kidnapping of settler's children. One being the three-year-old son of Jacob Pruden. Mr. Pruden settled in the county in 1829 near what was called the old Seuier place, about five miles below the present site of Hardin. The boy was recaptured from the Native Americans five days after he had been taken, and had not been harmed. The second case was the kidnapping of Joe DeGerlia, the son of Antoine DeGerlia Sr., the first settler in the French Hollow area. Mr. DeGerlia had not yet finished building his home, when his small son, Joe, was taken, however the family oral history may suggest Joe was bartered or sold. Nearly thirty years later a man who was acquainted with the history of the DeGerlia family was traveling among the tribes of the Indian Territory, and there he heard the story of a boy that had been kidnapped many years before from a place not far from where the Illinois River flows into the Mississippi. He investigated the story and found that the boy was Joe DeGerlia of a family in Calhoun. Joe had been taught the Native's language and had grown to manhood among the remnants of the tribe that had taken him southwest. Joe returned to Calhoun, married, and lived in the French Hollow area. The descendants of the DeGerlia family are still living on the same land Antoine DeGerlia settled over 200 years ago.

The most well-known historical event to impact Calhoun County is likely the Great Flood of 1993. Calhoun County is a peninsula nestled between the Illinois and Mississippi Rivers, which both saw record flooding during 1993. The Great Flood of 1993, the name it is now known as, impacted several villages in Calhoun and completely destroyed the village of East Hardin which once sat across the Joe Page Bridge when the Nutwood levee broke in August 1993. The flood also closed all crossings over the rivers in the county including the bridge in Hardin and all ferries, leaving residents without access to groceries, gasoline, or other supplies. All supplies needed had to be flown in via helicopter or retrieved on a 2 hour long drive north via the only road existing Calhoun without a water passage or was not covered by flood water. The Great Flood of 1993 was devastating to Calhoun County because it destroyed homes, infrastructure, and caused many residents to leave. The population of the county has yet to recover.
