I find fault with certain aspects of the Southern Victory/TL-191 Series that pretty much renders it border-ASB.
First of all, France might take the chance to recognize the CSA, but Great Britain most likely will not. Great Britain has already abolished slavery, and is one of the most anti-slavery countries at the time. Even though the United States has not abolished slavery yet, it is already going down the path, and within a few years slavery would have been abolished in the United States. Great Britain also has numerous influential abolitionists in power, and since the CSA espouses slavery, Great Britain will not support such a state.
Second of all, Turtledove's timeline is too parallel to OTL, with our events corresponding roughly to their events. The butterflies from this POD might have affected German Unification, The Second Mexican Empire, the Russian-Turkish War (If Great Britain supported the Ottoman Empire here like in the Crimean, I could see a Russian-German or a Russian-Austrian alliance here, completely changing WWI), European imperialism in Africa, the rise of Japan as a major power, numerous "crises" in European colonies, and the Balkan Wars of 1910s, all which have resisted change in his timeline.
Therefore, I am beginning to start a timeline with the same POD as Harry Turtledove's TL-191, but will be more to the tune of successful timelines here like Disaster at Leuthen, Male Rising, and Dominion of Southern America. Although I mention those three timelines, I am not a terrific writer, so each part of my timeline would not be as long as the parts of those timelines. This is my first timeline, so any comments and suggestions are welcome.
