After the end of WW1 you had a decent ammount of social unrest, especially in the industrial centers of the north and the rural regions of the centre-north, leading in some cases to civil-war similar situations. The revolts were however suppressed by the state and, especially in the rural areas, by fascist militias. Besides that, the vast majority of the elites and the security apparatus opposed them, so ther's no real possibility they might have succeded.

In hindsight there was no real threat of Bolshevism and a full scale socialist uprising at all, however the horrors of the recent and ongoing civil war in Russia had a hughe impact on the mentality of conservatives, liberals, fascists and even social democrats all over Europe. Anti-Bolshevism was almost the cornerstone of fascist propaganda and the main link to conservatives: It justified the fascist regime in Italy, the coup d'état of the spanish generals and the following civil war, as well as the invasion of the soviet union, which, for instance, was portrayed as an common effort of protecting Europe against the "barbarity of bolshevism."
