Benito Mussolini was an Italian politician and leader of the National Fascist Party who ruled Italy as Prime Minister from 1922 to 1943. He consolidated power by inviting the King to make him Prime Minister in 1922. He then centralized power by becoming the Head of State in 1925 and holding multiple cabinet positions. He pursued an imperialist foreign policy of expanding Italian territory through the invasion of Ethiopia and Albania. However, his government was plagued by ineptness and an inability to supply the military in World War 2, leading to Italy's defeat and Mussolini's execution in 1945.
