Benito Mussolini was an Italian political leader who founded and led the National Fascist Party. He became the Prime Minister of Italy in 1922 and ruled as a dictator under the title "Il Duce" until 1943. Mussolini played a key role in the creation of fascism, a far-right, authoritarian political ideology that emphasizes nationalism, dictatorial power, and the suppression of opposition.   Mussolini was born on July 29, 1883, in Predappio, Italy. He was the son of a blacksmith and a schoolteacher, growing up in a working-class family with strong socialist influences. Mussolini himself was initially a socialist, but he broke away from the movement during World War I, advocating for Italy's participation in the war and ultimately embracing nationalism and militarism.   In 1919, Mussolini founded the Fasci Italiani di Combattimento, which later evolved into the National Fascist Party. His rise to power was marked by the infamous March on Rome in 1922, after which King Victor Emmanuel III appointed him as Prime Minister. Mussolini quickly dismantled democratic institutions and established a totalitarian regime that controlled all aspects of Italian life.   Mussolini's ambition led him to form an alliance with Nazi Germany during World War II, a decision that ultimately contributed to his downfall. After years of military failures and growing resistance within Italy, Mussolini was deposed in 1943. He was captured and executed by Italian partisans on April 28, 1945, in the small village of Giulino di Mezzegra. His death marked the end of fascist rule in Italy.
