Actually, the Civil War is framed as a war over state's rights, at least from a Southern conservative perspective.
The Southerners were first demanding the federal gov't keep its hands out of state's rights and also railing against the economic sanctions the North was putting on the South for pursuing the "rights" the southern states deemed proper, namely slavery.
Remember, the Republicans of the era were considered the fairly progressive, or liberal, political party while the Democrats were the fairly conservative political party and heavily concentrated in the South.
Of course, the "state's rights" argument the Southerners used was just a cover for keeping slavery as an institution, but that's irrelevant.![]()
Secession was simply the straw that broke the camel's back.
Th thing is that they weren't covering for slavery at all back then. They were very explicit about how much they liked slavery and how intent they were on keeping it.
It has only been in more modern times that historical revisionists have attempted to whitewash the confederacy.
