The March on Rome was an organized mass demonstration in October 1922 which resulted in Benito Mussolini's National Fascist Party ascending to power in the Kingdom of Italy. In late October 1922, Fascist Party leaders planned a march on the capital. On 28 October, the fascist demonstrators and Blackshirt paramilitaries approached Rome; Prime Minister Luigi Facta wished to declare a state of siege, but this was overruled by King Victor Emmanuel III, who, fearing bloodshed, persuaded Facta to resign by threatening to abdicate. On 30 October 1922, the King appointed Mussolini as Prime Minister, thereby transferring political power to the fascists without armed conflict. On 31 October the fascist Blackshirts paraded in Rome, while Mussolini formed his coalition government.

Benito Amilcare Andrea Mussolini was an Italian dictator who founded and led the National Fascist Party (PNF). He was Prime Minister of Italy from the March on Rome in 1922 until his deposition in 1943, as well as Duce of Italian fascism from the establishment of the Italian Fasces of Combat in 1919 until his summary execution in 1945 by Italian partisans. As dictator of Italy and principal founder of fascism, Mussolini inspired and supported the international spread of fascist movements during the inter-war period.
