Benito Mussolini

Benito Amilcare Andrea Mussolini (1883–1945) was the founder of Italian Fascism and head of government of the Kingdom of Italy from October 1922 until July 1943. Originally a socialist journalist and editor of Avanti!, he broke with the Italian Socialist Party over Italy's entry into World War I and founded the Fasci Italiani di Combattimento in Milan in March 1919, which became the National Fascist Party (PNF) in 1921.

Following the March on Rome in October 1922, King Victor Emmanuel III appointed Mussolini Prime Minister. Over the next several years he dismantled parliamentary democracy, particularly after the murder of socialist deputy Giacomo Matteotti in 1924 and the leggi fascistissime of 1925–1926, which banned opposition parties and established a one-party state. He styled himself Il Duce ("the Leader") and built a corporatist economic system and a cult of personality.

In foreign policy, Mussolini signed the Lateran Treaty with the Holy See in 1929, resolving the "Roman Question" and creating Vatican City. Italy invaded Ethiopia in 1935–1936 in violation of the League of Nations Covenant, intervened on Franco's side in the Spanish Civil War, and formed the Rome–Berlin Axis with Adolf Hitler in 1936. The Pact of Steel (1939) and Tripartite Pact (1940) formalized the alliance with Germany and Japan. Italy entered World War II in June 1940.

Military defeats in Greece, North Africa, and the Allied landings in Sicily led the Fascist Grand Council to vote against Mussolini on 25 July 1943. He was arrested, then rescued by German commandos and installed as head of the puppet Italian Social Republic (Salò Republic) in northern Italy. On 28 April 1945, Italian partisans captured and executed him near Lake Como.

His regime is the original referent for the term "fascism" in political science and remains a standard case in studies of authoritarianism, propaganda, and interwar diplomacy.
