History
St. Clair County was established on November 20, 1818, by the Alabama Territory legislature by splitting the area from Shelby County. [1] [4] The county seat was incorporated and named "Ashville" in honor of John Ash. [1] In 1836, a portion of St. Clair County was separated to establish Cherokee County and DeKalb County. In 1866, after the Civil War, a northeast section of the county was used to create Etowah County. [1]
Due to the relatively high terrain of the far southern end of the Appalachian Mountains which divides the county in a northeast–southwest orientation, and the difficulty of communication and administration from either side of the county to the other, a second county seat was established in Pell City to better provide administration and services to the southeast side of the county. [5]
In 2019, St. Clair County became the seventh county in Alabama to adopt its own flag. [6]
