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 (PNF) ascending to power in the Kingdom of Italy. 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.[1][2]

On 24 October 1922, Mussolini declared in front 60,000 militants at a Fascist rally in Naples: "Our program is simple: we want to rule Italy."[5] On the following day, the Quadrumvirs, Emilio De Bono, Italo Balbo, Michele Bianchi and Cesare Maria de Vecchi, were appointed by Mussolini at the head the march, while he went to Milan. He did not participate in the march, though he allowed pictures to be taken of him marching along with the Fascist marchers, and he comfortably went to Rome the next day.
