In the words of the Bloody Goon from Illinois the war was not about slavery. Do some research.
My research tells me the Southern states in rebellion seceded to defend slavery.
“The new Constitution has put at rest forever all the agitating questions relating to our peculiar institution—African slavery as it exists among us—the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution.”
