History
DeKalb County was created in 1822 from Henry, Gwinnett and Fayette Counties. It was named for Baron Johann de Kalb, a German soldier who fought on the side of the Americans in the American Revolutionary War. In 1853, Fulton County was formed from part of DeKalb. Until this time, the growing city of Atlanta had been inside DeKalb. During the American Civil War, much of the Battle of Atlanta was fought in DeKalb. Until the 1960s, DeKalb was a mainly agricultural county, but as Atlanta and its suburbs grew, DeKalb became more urban.
