National Fascist Party was the ruling party of the Kingdom of Italy from 1922–1943. Benito Mussolini founded the party in 1919 and served as it's Chairman (Italian:"Presidente del Partito Nazionale Fascista") from 1919–1943. The Party came to power after Mussolini led thousands of Blackshirts in a march on Rome and forced King Victor Emmanuel III to appoint him Prime Minister. As Prime Minister (the "real" head of government), Mussolini banned all other political parties and established a one-party police state, which lasted until he was thrown out of power by his own citizens- and ordered to be arrested- by the King in 1943. After Mussolini's arrest, the National Fascist Party was destroyed.
