If the South was fighting for slavery during Lincoln's War, who was fighting against slavery?

I say “Lincoln's War” to distinguish that war from the first Revolutionary War when, history records, all thirteen states agreed to fight for slavery.

Nobody directly. The North's motivation for pursuing the war that the South started was not to end slavery. As it happened, the end of that institution was a fortunate outcome but not the reason for the war itself.

That's the first time I've heard that the American Revolution was motivated by slavery.
