This is a re-do of one of my older maps for my (now-defunct) timeline, sigged below.
Germany goes socialist after WW1, although think more Scandinavia than USSR (though it's labelled red) though due to tensions with Imperial Rusia (1917 fails) there's a second Great War, which Britain and France stay out of.
Basically Russia tries to re-annex territory it lost during the Great War but just as Lithuania's falling, it declares itself a social democratic state and calls for German aid; Germany, worried that Poland and Czechoslovakia will be next, issues an ultimatum and in 1940 war is declared. It rages for six years, involving poison gas and it's only ended when German bombers based in Finland demonstrate their capacity to reach Russia's trans-Uralian industries. The war ends with most of Eastern Europe under Germany's thumb. They range from Czechoslovakia, which is a democratic-socialist state with elections and a GDP per capita comparable to western Europe, to Romania which is a quasi-Stalinist hell hole supported by German arms.
After the war, fearing German might, France and the Benelux countries formed the Western Entente, a mutual defence pact that evolved into the European Commonwealth, formed in 1967 in Bruges, which bound the nations and their colonial empires together. Decolonisation has taken a different turn; some former-colonies, such as Senegal, have entered the EC as sovereign nations while others, like Cote d'Ivoire and Benin, have remained integral parts of France. Large parts of Africa remained organised Territories, deemed too underdeveloped for full admittance yet still governed by the Commonwealth. British involvement with the EC has flitted from Halifax's entrance of the Western Entente in 1942 to the 1972 Anglo-European split, where the Eurosceptic Labour government left the Entente and broke with the EC in favour of diplomatic rapproachment with Germany and her allies.
Italy remained fascist and formed the Eastern Pact with Bulgaria and Turkey in order to invade Yugoslavia and Greece, which occurred in 1944 while the world's eyes were to the north. The alliance remained together until 1976, when the map is set, and the Balkan Spring. Higher standards of living and German and EC prosperity have inspired a series of risings in eastern Europe. The Turkish junta has fallen, as has the Bulgarian Tsar and the Serbian dictatorship. Now unrest is spreading west, even to Italy itself. Hardship caused by the enormous cost of maintaining Italy's colonial empire have taken their toll and now it seems that fascism is under threat. The question is will the regime go quietly, or will it blame insurrection on German influence and brutally crack down. Only time will tell...
