“That’s what happened after the war ended.”
Slavery in the Southern states would have ended without that War.
How soon? Sadly, we will never know.
Great, after the blue states collapse we can make them colonies
So what are you saying, that it would have been all right for the confederacy to hold on to the slaves until they were ready to free them?
And if they were planning abolish slavery, the why do the articles of secession from all of the states mention slavery as a reason for seceding?
