The Kingdom of Italy was governed by the National Fascist Party from 1922 to 1943 with Benito Mussolini as prime minister transforming the country into a totalitarian dictatorship. The Fascists crushed political opposition, while promoting economic modernization, traditional social values and a rapprochement with the Roman Catholic Church. They also promoted imperialism, resulting in the expansion of the Italian Empire.
According to historian Stanley G. Payne, "[the] Fascist government passed through several relatively distinct phases". The first phase (1922–1925) was nominally a continuation of the parliamentary system, albeit with a "legally-organized executive dictatorship". In foreign policy, Mussolini ordered the pacification of Libya against rebels in the Italian colonies of Tripolitania and Cyrenaica (eventually unified in Italian Libya), inflicted the bombing of Corfu, established a protectorate over Albania, and annexed the city of Fiume into Italy after a treaty with the Kingdom of Yugoslavia. The second phase (1925–1929) was "the construction of the Fascist dictatorship proper". The third phase (1929–1935) saw less interventionism in foreign policy. The fourth phase (1935–1940) was characterized by an aggressive foreign policy: the Second Italo-Ethiopian War, which was launched from Eritrea and Somaliland; confrontations with the League of Nations, leading to sanctions; growing economic autarky; the invasion of Albania; and the signing of the Pact of Steel. The fifth phase (1940–1943) was World War II itself, ending in military defeat, while the sixth and final phase (1943–1945) was the rump Salò Government under German control.
