My entry for MotF 45: A communist Greater Germany.
In this timeline, after a First World War that goes on for another two years, the German Spartacist/KPD movement gathers enough momentum and supporters that it successfully takes control of Germany. Soon after the German Revolution communist revolts break out across Europe, supported by the German Red Armies. Chaos reigns, and after the dust has settled from what became known as the European Revolution the Union of European Worker's Republics was created, stretching across Europe from the North Sea to the Adriatic.
The UEWR is formed out of 12 "equal" Worker's Republics, listed on the map below. In practice the 7 German Republics usually vote in the Supreme Worker's Council together, and as such they remain listed under the old German Union. This is partially why there has been resistance to integrating Hungary and Denmark into the UEWR.
Anyway, the map:
The Union of European Worker's Republics: The major power in Europe, also holds a lot of power through supported socialist states in Africa, Asia and South America.
The Alliance of Free Nations: The name given to the alliance between the UK, France and the US (not shown), with several other countries tapped on mainly for protection. Mainly very uneasy about combating enemies from either side, often engages in proxy wars with the UEWR.
The Tsarist Empire of Russia: Revolution in Germany provided a new focus and a much bigger goal for the Communists. Russia became an extremely despotic state; though it is slowly modernising in every field other than political.
The Rome-Madrid Axis: Key players in Europe but not huge internationally. Often is forced to work with the other side; e.g. exchanging Südtirol for Italian Switzerland. Their closely growing bonds with Greece may well drag them into a war some time soon.
Key to numbers on the main map:
1 Ireland was so close to full independence, but the socialists getting involved forced the UK's hand.
2 Not a happy place if you are European, along with the rest of Red Africa. Only cordial links with the UEWR.
3 They get very annoyed if you call them French. They get EVEN MORE annoyed if you suggest they should rejoin the rest of the Low countries. If you then go on to mention Brussels they are likely to be excused from the dinner table.
4 Don't really like any side but neutrality didn't work last time. Side with the French and forget Geneva...
5 ... who wanted rump Switzerland to join France; the other cantons called their bluff and kicked them out.
6 Berlin's not that interested in Denmark per say, but Greenland on the other hand...
7 One thing about the Reds; they tend to like ethnic borders. The Poles could live with this,...
8 ... the Czechs on the other hand have the opposite opinion.
9 A slight oddity of history. Not a great place to live, but any complaints and the neighbours would be more than happy to step in.
10 Brought back into the Tsarist sphere after a hard fight.
11 Part of 10. Consider themselves lucky they could chose Helsinki over Moscow or (God forbid) Berlin.
12 Not many Poles nowadays, but still enough to resist Russian calls for a Finland-like status.
13 Like the idea of this Fascist idea, just the thing for Cyprus. Close to becoming a full Axis member.
14 Can't ally with the Russians or Greeks for obvious reasons, and the Allies are both to far away and too close for comfort. As such kind of left hanging, hoping to form a fifth(!) power bloc with those Middle Eastern states that aren't red yet.
