From Wikipedia: The March on Rome (Italian: Marcia su Roma) was an organized mass demonstration in October 1922, which resulted in Benito Mussolini’s National Fascist Party (Partito Nazionale Fascista, or PNF) ascending to power in the Kingdom of Italy (Regno d’Italia). In late October 1922, Fascist Party leaders planned an insurrection, to take place on 28 October. When fascist troops entered Rome, Prime Minister Luigi Facta wished to declare a state of siege, but this was overruled by King Victor Emmanuel III. On the following day, 29 October 1922, the King appointed Mussolini as Prime Minister, thereby transferring political power to the fascists without armed conflict.
