Biennio Rosso

The Biennio Rosso (English: "Red Biennium" or "Two Red Years") was a two-year period, between 1919 and 1920, of intense social conflict in Italy, following the First World War. The revolutionary period was followed by the violent reaction of the fascist blackshirts militia and eventually by the March on Rome of Benito Mussolini in 1922.
