Interesting fact of the day: Lincoln's Emancipation Proclamation **only** freed the southern slaves and kept the north slaves legal and enslaved. It was a sort "screw you to the south" more so than to abolish slavery.
Lincoln only supported and pushed through the 13th amendment once slavery was voluntarily abolished at the state level first.
@threalist Yup, it was all the states that bordered the south but were in the north.
Though technically you could argue after the emancipation proclimation (since the north is the legal recognized government) the north was the only region left with slaves after that moment..
Of course the reality is more complex since southern states didnt recognize the authority. But at least from the perspective of the north, as the one true government, after that point slavery existed **only** in the north (legally).
@freemo @threalist Speaking of border states, one problem the South had was all the high tech industry was either in the North or in those border states that sided with the North.
The Confederates built a big powder mill - one of their few industrial successes - and they had to confiscate a Northern made steam engine to make it go!
They also wound up pulling railcars with horses because their steam locomotives were broken and they could not fix them.
@threalist @freemo Wow that's a lot. I know the South actually had a lot of slaves forced to fight for it. And there were a surprising number of Southern men - like 200K - that left to join the Union army.
The non land-owning white Southerner had to know that slavery did not serve his interests. It depressed wages and allowed the Boss to treat him with contempt. So he had to wonder "what's in it for me."
I think that is what the "Golden Circle" invade Mexico idea was for. Were they serious?
There is no doubt a large portion of the south were fighting for their right to decide for themselves how to handle slavery (and wanting to keep it, at least in the short term)...
But you are right, there are many nuanced factors overall.
