So, as we all know, the American Civil War was rather odd in that the southern states sought to break away from the Union into their own country, making it more a rebellion than anything else. So, would it have been possible, with a reasonable POD (sometime in the 1850s?), to have a civil war in which the southern states simply wish to fight to reform the government more to their liking? Like, perhaps, force Lincoln out of office and put their own president in his spot?
