In the 1920s the Bolsheviks hoped that if they steamrolled over Poland and reached Germany, the German workers would rise up and overthrow the German Bourgiouise. Any reading material that goes into the reasons why that didn't occur and we got a spiral into fascism instead?
Yeah there was one and it was crushed by the state (or rather a second phase was, the revolution against the Kaiser succeeded). Then there was another (much larger) one in 1920 to counter the kapp putsch that was also crushed. The strikes were not large enough, and not enough of the army rebelled. Luxemburg and Liebknecht were extremely apprehensive about the the January uprising and thought it was premature, but once it got rolling in the streets of Berlin it was too late to stop. It ended tragically for them. After the surrender, a citizen militia found them after storming an apartment building. They were taken to the Garde-Kavallerie-Schützen-Division, the largest Friekorps unit, headquarters. Liebknecht was beaten, taken to a park and executed. He showed up in a morgue days later. Luxemburg was beaten, possibly to death, then shot in the head and thrown in the Landwehr Canal. Her body was recovered in June of that year.
