<Li> Greco - Italian War </Li> <Li> Second World War </Li> <P> Benito Amilcare Andrea Mussolini (/ bəˈniːtoʊ mʊsəˈliːni, muː - /; Italian: (beˈniːto mussoˈliːni); 29 July 1883--28 April 1945) was an Italian politician and journalist who was the leader of the National Fascist Party (Partito Nazionale Fascista, PNF). He ruled Italy as Prime Minister from 1922 to 1943; he constitutionally led the country until 1925, when he dropped the pretense of democracy and established a dictatorship . </P> <P> Known as Il Duce ("The Leader"), Mussolini was the founder of Italian Fascism . In 1912, Mussolini had been a leading member of the National Directorate of the Italian Socialist Party (PSI), but was expelled from the PSI for advocating military intervention in World War I, in opposition to the party's stance on neutrality . Mussolini served in the Royal Italian Army during the war until he was wounded and discharged in 1917 . Mussolini denounced the PSI, his views now centering on nationalism instead of socialism and later founded the fascist movement which came to oppose egalitarianism and class conflict, instead advocating revolutionary nationalism transcending class lines . Following the March on Rome in October 1922, Mussolini became the youngest Prime Minister in Italian history until the appointment of Matteo Renzi in February 2014 . After removing all political opposition through his secret police and outlawing labor strikes, Mussolini and his followers consolidated their power through a series of laws that transformed the nation into a one - party dictatorship . Within five years, Mussolini had established dictatorial authority by both legal and extraordinary means and aspired to create a totalitarian state . Mussolini remained in power until he was deposed by King Victor Emmanuel III in 1943, but a few months later he became the leader of the Italian Social Republic, a German client regime in northern Italy--Mussolini held this post until his death in 1945 . </P>
