DeKalb County was created by the Alabama legislature on January 9, 1836,  from land ceded to the Federal government by the Cherokee Nation. It was named for Major General Baron Johann de Kalb, a hero of the American Revolution. 
The county's eastern edge, along the state line, was also the epicenter of an earthquake on April 29, 2003, measuring 4.6 on the Richter scale. Power was knocked out in the area, mirrors and pictures thrown to the floor, foundations cracked, and one chimney fell to the ground. It was felt over a significant portion of the southeastern states, including quite strongly in northeastern Alabama and neighboring northern Georgia, and nearby eastern Tennessee (especially near Chattanooga). It was also felt slightly in western upstate South Carolina, far west-southwestern North Carolina, south and southeastern Kentucky, and east-northeastern Mississippi.
On the whole, DeKalb County is a dry county. In 2005, a change in local laws enabled Fort Payne to become the only location in the county to allow the legal sale of alcohol.  Collinsville and Henagar later allowed alcohol sales.
DeKalb County saw one of the highest death tolls in Alabama during a massive tornadic system in April 2011, the 2011 Super Outbreak, with 31 deaths reported in the county.

DeKalb County is strongly Republican. Eighty-three percent of its voters supported Donald Trump in 2016, and no Democrat has carried it since Southerner Jimmy Carter did so in 1976. Populist appeal in the county during the period of “ Redemption” meant that even during the “ Solid South” era DeKalb County sometimes supported victorious Republican presidential candidates, as it did during the three Republican landslides of the 1920s.
