Here is another source, Robert Toombs' speech to the Georgia Legislature. He makes no bones about it, the issue is slavery and the election of that Republican Lincoln who is opposed to it.

Toombs was later appointed CSA Secretary of State, but he resigned to join the Army. He was a brigade commander at Antietam. I asked our guide about him, remarking that if I remembered correctly he was a real fire breather. The guide didn't respond. Maybe they are not supposed to be overtly Northern or Southern. Or maybe he didn't know who Toombs was apart from being another Confederate General.

In the end, the south sought to preserve slavery instead of the Union.

Again, I ‘m getting ahead of things, but I wonder how the Southern legislators and Governors squared secession with their oath under Article VI to uphold the Constitution of the United States.
