What a ****ty history teacher you had.
The south started the war by bombarding Ft. Sumter. I guess Lincoln was invading them with ****ing ghosts hahaha.
Slavery was the cause of the civil war. States rights was the rallying cry so the poor folk who didn't own slaves (aka the ones dying in the war) would fight. If they strictly said "We're doing this to own slaves" most people would be like, "Nah, **** you" if slavery wasn't the main reason, then why didn't the resolution to ban importing African SLaves pass? Despite the massive potential boom from it?
