I have been reading this from the start, and have been loving every update. I love your concept of mixing MDS with KR, makes for some exciting possibilities.
I must say, I am surprised that Shangqing conquered all of China. Also, it is interesting that Mittelafrika made it through the 20th century. I guess without a 2nd world war, decolonization never got off the ground. It wouldn't be surprising to see LOTS of terrorist and guerrilla activity against German rule in Mittelafrika. Also, its nice to see that the USA won the civil war.
One little nitpick: When you showed the borders of Mittelafrika, they owned both Botswana and Zimbabwe (which I guess in TTL would still be Rhodesia). Didn't South Africa still own them? Or did Mittelafrika seize them at some point over the years?
Yeah, maybe some things look odd, but they can be explained. I have already mentioned history of some nations in past updates.
I think it is best option that Shangqing China won against other Chinese factions. This fact offers better story. Imagine pro-German Qing Empire or German corporation conquering all of China. I think it is realistic that Chinese chosed theocratic state as this kind of society offered them best options. Shanqing was fighting for free China, they presented new ideas and strong China. Corrupted cliques and Qing Empire didn't enjoy support of the people. Shanqing armies that were fighting for their strong ideas were armed with outdated weapons, but they had strong fighting spirit, bravery and loyalty. Other people of China were not willing to fight and die for corrupted warlords and German imperialists.
Mittelafrika was not so fragile as it seem. I already mentioned that Germans offered many rights to native African people. They were not classical colony which would serve only as base of resources. Germans were investing in African economy and they tried to achieve good relations between African and European population. They also propagated African unity, like African people are one nation etc. People of Mittelafrika were enjoying more rights than population of French North and West Afrika, where French elites dominated society. Mittelafrika is facing new threats after rise of Syndicalism in Ethiopia. Ethiopians are propagating creation of great African nation where everyone are living in equality. Their ideas are combination of socialism and rastafarian movement. Combination like this attracted many people of Mittelafrica, especially African labour class. As for African wealthy middle class, they support German Mittelafrika which is free trade zone that offers many chances for business. As you see, Africa is not so particioned because of special historical situation. Instead of national conflicts, there is more like conflict between pan-African European capitalism and pan-African socialism, mixed with African tradition. Mittelafrika was also a bit of bully, this is why it expanded into Portugese colonies and into South Africa. In war with Portugal(which is included in classical KR scenario), Portugese lost their colonies. I have also added story where Spain joins Mitteleuropa and conquers metropolian Portugal. There was also war with South Africa(also included in KR scenario). Entente couldn't protect South Africa, but maybe it will help their old friends later. South Africa is now member of Entente alliance. It is African fortress of Liberal Democracy(Germans are propagating Conservative Aristocratic Democracy). If there will be war between Entente and Mitteleuropa, South Africa will try to liberate other parts of Africa.
As for United States, in update about Entente Conference in Canada, Canadian PM was talking about Canadian intervention in US civil war. Canada declared war on Reed's CSA and Californian PSA. This allowed MacArthur to defeat Southerns without fighting on two fronts, while swift Canadian intervention prevented Mexican invasion of California. With Canada defeating PSA and CSA, Mexicans decided not to intervene in American war. In long era of peace, USA became very strong. Altough Canada is still formal leader of Entente, USA has became strongest nation in alliance and de facto leader of it.
I hope I have explained some things to you, many people were asking about them and this is short explanation. As you see, world is partitioned between many alliances, forces of liberal democracy(free market and liberal political values), aristocratic democracy(conservative political values and free market with some limitations) and peoples democracy(state controled economy- Socialists and very limited free market- Social Radical). There are also small alliances like Belgrade pact(Serbia-Romania-Greece) and Treaty of Tehran(Persia-Oman-Egypt-Turkestan). There is still misterious Chinese alliance(Shanqing-Alash Orda-Indonesia). I thing I have answered on most of questions that were asked by readers. Thanks for reading and commenting.
