Dating back to 1822, the county was named in honor of Johann DeKalb, a peasant mercenary who fought for the colonies in the Revolutionary War under the name "Baron Jean deKalb."

Mills and ginneries were vital to the county's early growth. This heritage lives on in the names of various DeKalb roads that once led to these mills, such as Browns Mill, Evans Mill and Henderson Mill.

The county's previous courthouse was built in 1917 at a cost of $10,000. DeKalb's present courthouse was built in 1965 at a cost of $3.5 million, while the old facility has been renovated and serves as the headquarters for the DeKalb Historical Society.
