Alabama's Historic Marker Program
The Alabama Historical Association (AHA) began sponsoring historical markers as early as 1950. The AHA is the oldest statewide historical society in Alabama. Their mission is "to discover, procure, preserve, and diffuse whatever may relate to the natural, civil, literary, cultural, economic, ecclesiastical, and political history of the state of Alabama."
