A South Divided is an account of Southern dissidents in the Civil War, at times labeled as traitors, Tories, deserters, or mossbacks during the war and loyalists, Lincoln loyalists, and Unionists by historians of the war.

In recent years there has been an upsurge of interest in Southern dissenters among specific groups or communities. But A South Divided presents a panoramic overview of Southern dissent. What emerges is a complex pattern of dissent involving every state of the Confederacy and every year of the war. All of these people and groups had their part to play in the epic drama that sapped the strength of the Confederacy from within. They were rebels against the rebellion.
