Moultrie County is a county in the state of Illinois, USA. It's like a smaller region within the state. In 2020, about 14,526 people lived here. The main town, or county seat, is Sullivan. The name "Moultrie" is said like "mole tree." This is different from how its namesake, a hero from the American Revolutionary War named William Moultrie, said his name.

History of Moultrie County

Moultrie County was created in 1843. Land for the county was taken from Shelby and Macon counties. It was named after South Carolina General William Moultrie. General Moultrie was famous for defending Sullivan's Island, South Carolina, from a British attack in 1776. This place was later named Fort Moultrie. Another nearby county, Jasper County, was named for Sergeant William Jasper, who was also a hero at Sullivan's Island.

The official flag of Moultrie County is the Moultrie Flag. General Moultrie designed this flag. It flew over the new fort on Sullivan's Island during the battle. This flag became a symbol of freedom in the southern states.

When some people wanted to create this new county, they needed land from other counties. Macon County gave up some land that was thought to be "worthless swamp." Today, this land is very fertile and good for farming. Shelby and Coles counties didn't want to give up their land at first. But eventually, Shelby County gave some land, which created a zig-zag border with Moultrie County.
