Confederate oath of allegiance
The Confederate oath of allegiance, an oath of allegiance to the Confederate States of America, was taken by officers and enlisted men of the CSA (1861–1865) during the American Civil War. In contrast to the American oath of allegiance, Confederates swore "allegiance to the Confederate States without mention of allegiance to their constitution." Confederate oaths varied somewhat by state, and in the spirit of the CSA's proclaimed preference for states' rights over a unified federal government with majority rule and minority rights, Confederate oaths were often made to specific state governments.
