In the Southern Victory series the Red Rebellion is an uprising of black confederates who rose up in 1915. About 10% of the blacks in the CSA participated and they caused serious damage to the confederates in the process especially with US support. So what i'm wondering is, what would be the outcome if this rebellion somehow managed to succeed against all of the odds? Would it be an OTL style union of Socialist republics? What would have to happen to make this even possible? How would this effect the post war years?
