The war had NOTHING to do with slavery. Slavery was brought into the mix by Lincoln to keep Europe out of the fight. England and France were siding with the south. They had already ended slavery, and when Lincoln made it about slavery, they could not step in and side they the CSA any more without the obvious hypocrisy. The emancipation proclamation was a joke. It freed no one. Lincoln was the worst president in the history of the USA. The Declaration of Independence alone gives states the president to secede from the VOLUNTARY union.
