Historical Trajectory

Phase I: Rise

Alabama's secession convention met in Montgomery in January 1861, voting 61–39% to leave the Union and inviting other slaveholding states to form a southern republic. Governor Andrew B. Moore seized federal forts at Mobile Bay and the arsenal at Mount Vernon before secession was finalized, distributing weapons to Alabama towns. Only seven Cotton States of the Lower South initially joined Alabama in forming the Confederacy, with Montgomery serving as the new nation's first capital.

Phase II: Zenith

Alabama contributed substantially to the Confederate war effort, supplying troops, military leadership, food, horses, mules, and industrial materiel. Its Gulf Coast ports remained operational for nearly four years despite Union naval blockades, sustained by blockade runners protected by Forts Morgan and Gaines, floating mines, and obstacle paths. The state's divided population saw most Unionists concentrated in northern Alabama, while the majority of citizens supported the Confederate cause and served in its forces.

Phase III: Decline

Alabama's role in the war ended as Union forces closed its remaining strategic assets. The Battle of Mobile Bay in August 1864 broke Confederate naval control of the coast, and the Battle of Fort Blakeley in April 1865 forced the surrender of Mobile, the last major Confederate port. With the Confederacy's collapse in April–May 1865, Alabama came under Union military occupation and faced the political and social upheaval of Reconstruction.
