If the South won the American Civil War, would slavery over time end up abolished in the US?

Computers are the new slaves. When we get true artificial intelligence then we will have another civil war for computer rights. Yes I think slavery would have eventually be abolished or moved onto another group ie computers.

Yes, but I don’t know how long.

I think so.

Although, I guess the more accurate question is would the Confederate states have abolished slavery. We wouldn’t even be the United States as we are today. Or, maybe we would have United again. I don’t know.

Perhaps. But as was clearly demonstrated, the rights and opportunities for black people would have to be brutally restricted, just as they were. The South managed for better than 100 years beyond emancipation to restrict and and successfully degrade half its resident population through fear and intimidation.

Impossible to know.

But my guess is that slavery would have continue to grow for a while, particularly in states south of the Mason Dixon line and any states affected by the Missouri Compromise. meaning that most of the Western US would have been open to (or legal) to keep slaves.

Now, slavery was really only useful in Southeast, where there was a good deal of rainfall and water and slaves would be useful in agriculture. Once you get west of Texas, and to some degree NW of Missouri, the climate (and agricultural potential) changes markedly. You can’t have a cotton plantation in Colorado or Utah, for example.

But the advent of tractors (and picking machines, and especially the internal combustion engine) would have spelled the end to manual agriculture and the need for slaves.

So in my estimation, slavery would have died out by around 1925–1930 of its own accord. And if it hadn’t by the time of the Depression, the Depression would have ended it for sure.

Yes. With the advent of modern, practical cotton picking machines developed in the 1950’s. But, like @elbanditoroso , I think it would have ended earlier.

Doubtful.
Chances are, they would have allied with Nazi Germany in WW2.

@elbanditoroso makes a point I think. The need for slaves would have dwindled eventually, as science and technology advances.
However, that doesn’t mean blacks and other slaves would have reached the status of equality, since that wasn’t the case in this war and years after.

Slavery would have ended in North America regardless of the Confederacy. What were they going to do, build the Great Wall of the South? The North would have continued to poach slaves from the South, the Underground Railroad would have chugged along, and the men in the South would have daily been faced with the possibility of (literally) shooting their own family. Remember, the South wasn’t fighting for control of the entire country (that was an impossibility), but for their right to leave the union of states and form a new union. The North was not going to allow that and had the sheer numbers of shoulders to impose their will.

The South was going to lose and slavery was going to be abolished. The timing was all that was in question – how long it was going to take. Even with a major setback for the North, slavery was due to be off the continent well before the turn of the next century.
