Benito Amilcare Andrea Mussolini (29 July 1883 – 28 April 1945) was an Italian politician, journalist, and dictator who led the Kingdom of Italy as a fascist dictatorship from 1922 until his overthrow in 1943. Known under his rule as Il Duce, he founded fascism in 1919 with the creation of the Fasci Italiani di Combattimento, which became the National Fascist Party (PNF) in 1921. Mussolini was appointed Prime Minister of Italy after the March on Rome in 1922, establishing a totalitarian fascist dictatorship. He oversaw Italy's participation in World War II as a prominent member of the Axis Powers, and was executed by the Italian resistance near the end of the war in 1945. Mussolini was originally a radical socialist journalist at Avanti!. In 1912, he became a member of the National Directorate of the Italian Socialist Party (PSI), but was expelled for advocating military intervention in World War I. In 1914, Mussolini founded a newspaper, Il Popolo d'Italia, and served in the Royal Italian Army until he was wounded and discharged in 1917. He eventually denounced the PSI, his views pivoting to focus on Italian nationalism, and founded the fascist movement, which opposed egalitarianism, and class conflict, and instead advocated "revolutionary nationalism" transcending class lines. In 1922, following the March on Rome, he was appointed prime minister by King Victor Emmanuel III. After removing opposition through his secret police and outlawing labour strikes, Mussolini consolidated power through laws, and illegal means, that transformed the nation into a one-party dictatorship. He ordered the Pacification of Libya, which is often considered a genocide. In 1929, he signed the Lateran Treaty to establish the Vatican City. Mussolini, especially after the Great Depression, espoused policies of autarky and corporatism. Mussolini's foreign policy shifted from cautious pragmatism to aggressive expansion and close alignment with Nazi Germany in the mid-1930s. Initially, he sought to expand Italy's influence without risking a major conflict with France or Britain, aligning with them during tensions over Austria. However, his invasion of Ethiopia resulted in condemnations from the League of Nations, which isolated Italy diplomatically. This pushed Mussolini toward Adolf Hitler, leading to a rapprochement and the formation of the Rome–Berlin Axis in 1936. Mussolini began militarily supporting Francisco Franco's forces during the Spanish Civil War. Although he acted as a mediator at the Munich Conference in 1938, his ambitions for territorial expansion and growing distrust of the Western powers led him to strengthen ties with Germany, resulting in the creation of the Pact of Steel in 1939. The wars of the 1930s cost Italy enormous resources, leaving it unprepared for the World War II; Mussolini initially declared Italy's non-belligerence. However, in June 1940, believing that German victory was imminent, he joined the war on Germany's side to share the spoils. Following defeats at the hands of the Allies and the landing in Sicily, the Grand Council of Fascism voted on the Grandi motion, which effectively ended Mussolini's leadership and restored powers to King Victor Emmanuel III who then immediately dismissed Mussolini as head of government and placed him in custody in July 1943. After the king agreed to an armistice with the Allies in September 1943, Mussolini was rescued by the Germans during the Gran Sasso raid. Hitler made Mussolini the figurehead of a puppet state in German-occupied north Italy, the Italian Social Republic, which served as a collaborationist regime of Germany. With Allied victory imminent, Mussolini and his mistress Clara Petacci attempted to flee to Switzerland, but were captured by communist partisans and summarily executed on 28 April 1945.
