DeKalb County, Georgia is a core county of the Atlanta metropolitan area and one of the most populous counties in the state. Its county seat is Decatur, though it contains no single dominant city and is composed of numerous vibrant communities and unincorporated areas. The county is a major economic and cultural hub, home to prestigious institutions like the Centers for Disease Control and Prevention and part of Emory University. It was created in 1822 from portions of Henry, Gwinnett, and Fayette counties and named for Johann de Kalb, a German-born hero of the American Revolutionary War.

History

The area was originally inhabited by the Muscogee and Cherokee peoples before being ceded in the 1821 Treaty of Indian Springs. The county was pivotal during the American Civil War, notably as the site of the Battle of Atlanta, a decisive engagement in the Atlanta Campaign led by Union General William Tecumseh Sherman. In the 20th century, it transformed from a rural area to a key suburban component of Atlanta, experiencing significant growth during the Post–World War II economic expansion. The county was a center of activity during the Civil Rights Movement, with figures like Martin Luther King Jr. living and working in the area, and was the site of important legal battles such as those argued by the NAACP Legal Defense and Educational Fund.

It is bordered by Fulton County to the west, Gwinnett County to the northeast, Rockdale County to the east, and Clayton County to the south.
