Moultrie County was formed in 1843 with areas taken from Shelby and Macon counties. It is named for South Carolina General, and later Governor, William Moultrie. General Moultrie defended Sullivan's Island, South Carolina from British attack in 1776. The site was later renamed Fort Moultrie. Nearby Jasper County was named for Sgt. William Jasper, another hero of the defense of Sullivan's Island.
The official flag of the county is the Moultrie Flag, which was flown over the new fortress on Sullivan's Island, when Moultrie defended it, and was designed by Moultrie. It went on to become iconic of liberty in the South.
When Abraham Kellar of Lovington, John Cook of Marrowbone, and John Fleming of Nelson proposed the formation of a new county from Macon, Shelby, and Coles counties, Macon gave up a strip of “worthless swamp” that is now among the most fertile land in the world, but Shelby and Coles voters refused to give up any land. Finally, Shelby County gave up some of its land to make a zig-zag border with Moultrie County.
