An addendum.
The War Between The States is a euphemism often used by pro-Confederate groups. The correct term is the Civil War if we believe that the United States is a country. The War Between the States was used to describe an Ununited States which was the goal of the Conferadacy, realistically, because they could never get all the Northern states to agree to it.
BTW, Dixie was appropriated by the South because of a publisher in New Orleans who ripped it off from a Northerner from Ohio, the author, Daniel Emmett of the Christy Minstrels who were popular on the New York stage. In short, a Northern song appropriated by the South. There is a strange history here that hasn't been covered about it by the leading authorities. I saw a mention of it in a book that maintains that it was created about "Dick's Farm", a theme park on Long Island run by a Mister Dicks as a replica of an antebellum plantation where the "slaves" were paid performers. Haven't found any other corroborations for this anywhere. Did the author of the songbook I read make it up? Interesting question.
Also, there were Northern versions of Dixie's Land that were directed at the South prior to and during the Civil War. There is also a case for the fact that Emmett might have written it as a parody on the popular Southern song of the time.
