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.
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.
That's the first time I've heard that the American Revolution was motivated by slavery.
“As it happened, the end of that institution was a fortunate outcome but not the reason for the war itself.”
Oh, I thought you had made the case the reason for the war was slavery. If you did not, many northerners who attended public schools do.
“That’s the first time I’ve heard that the American Revolution was motivated by slavery.”
I am not surprised. I am of the understanding that history isn’t taught in public schools much anymore.
If you read the DOI, I think you’ll find what I said is true.
