For the south, a leader like Robert E. Lee would have been (more than likely) asked to lead the country.

Any thoughts on personalities who might have risen to the presidencies of the North and South?

I would think that the American Civil War, had it ended in a truce, would initially be like the North/South Korea we see today: a no-mans land, not a bunch of interaction (at first). There was so much resentment at the real end of the war (northerners were held in disrepute b/c of the destruction the Southerners endured), that there would be lingering animosity. I do think that slavery would have ended in the late 19th century as the Industrial Revolution swept through the world, but the cultural superiority of the South in regard to African-Americans would have forced them to leave, causing some sort of “Great Migration”.

I don’t think that you would’ve seen the KKK as a movement if there had been peace, mainly because direct persecution of A-As would have still been allowed and probably encouraged.

As a divided country, the US and CS would be less likely to enter world politics in the late 1800s; “peace movements”, which were strong even then, would effectively limit the involvement in the world affairs, probably leading to German victory in WWI.

As for the leaders. Lincoln would never have won a second term in 1864 had the north lost, so a the country would probably be run by pacifist people for a while, at least. The desire then would be for peace and harmony between the US and the CS, leading to a normalization of relations by the turn of the century. In the CSA, the states were so dependent on STATES rights that there would be much friction between the states for a while, potentially leading to a E/W split as their differences grew. Many states were distrustful of one another, and Jefferson Davis really struggled to hold the confederacy together during the war.

I have much more to say, but I thought I’d start with this and see what you thought.
