Finally, a large updated map of my Pax Germania timeline.
In this world the central powers win a relatively quick victory in the West, and are able to achieve hegemony over Eastern Europe in their equivalent of WW1.
In the 30's the central powers and the Entente clash again in the Second European War, France an the UK are utterly defeated and loose most of their Empires to the central powers.
Things remain relatively quiet in the 40's and early 50's as Germany sets its sights on the Americas, increasing its influence until 1954 when they quickly conquer the United States (apart from a small enclave set up by the Canadians in Toronto).
Buoyed by their success Germany turns to China, the final possible threat. The wealth and resources of China could give the Entente a significant advantage were they to get organised, so in 1958 Germany invaded, and found they had severely underestimated the Chinese, with victory only coming in 1971 with millions of German soldiers dead. To secure China, Germany had had to call on it's allies. Austria-Hungary's had honed it's counterinsurgency skills in the Balkans and had managed to secure much of Southern China, with it being the least restive part of the whole nation. However, whenever the Germans tried to take over control the Chinese revolted. Germany is hesitant to transfer "Austrian China" directly to the duel monarchy as it would set a precedent that Finland, Turkey and the Netherlands could all try to exploit.
Meanwhile, Russia has been at war with itself since 1917. The White forces were much more organised with more support, allowing the war to continue for almost 80 years until in 1994, with the balance tipping in the Bolsheviks favour, the Central Powers invaded European Russia, setting up the Provisional Government of Russia. In Siberia the Monarchist and Mensheviks continue to battle the Communists.
To protect themselves from the central powers, without provoking them by joining the Entente (and visa versa) several diverse nations banded together to form the Non-aligned alliance, who's shared nuclear arsenal should discourage anyone form interfering with their sovereignty and neutrality.
