If Germany had been Balkanized after WWI the North and East were more commie than the rest. May have actually seen revolution in a subset. Of course the conditions of Balkanization would make a big difference, though.

The North + East are and were the more protestant areas while the South and Austria were more catholic. The latter were hotbeds of Nazis. Famously, the Hofbraeuhaus in Munich is where much of The Holocaust was decided.
