The Confederate States of America (also referred to as "The Confederacy" or simply "The South") had, like the
United States at the time, several patriotic songs in use which could have been considered anthems, like "Dixie", "The Bonnie Blue Flag", and "God Save the South", none of which were officially declared (possibly because declaring an official anthem wasn't as important to a new nation then as it is now).
"God Save the South" does have more of an anthemaic quality in the music and lyrics, and several publications of the song refer to it as a (or the) "anthem", and
was also the first song to be published in the Confederacy (which was subsequently published in at least nine editions).
