At the end of World War I, Europe was filled with unrest, especially in Germany, France, Poland, and Hungary. The year 1919 was filled with several failed socialist revolutions, beginning with the Spartacus uprising in Germany.
So, my question is, how can we get successful socialist revolutions in Germany, Poland, and Hungary, with a POD no earlier than 1919.
Further, none of these revolutions can be Bolshevik in nature--I'm looking for something more along the Luxemburgist variety: a large and developed proletariat rising up in an organized and orthodox Marxist fashion.
I'm looking to create a new TL, so as much help as possible is encouraged.
GO!!
