Historical Trajectory
Phase I: Rise
Benito Mussolini came to power on 31 October 1922, nominally within the parliamentary framework but rapidly consolidating an executive dictatorship. Between 1922 and 1929, the Fascist regime suppressed political opposition, pacified Libya, bombed Corfu, established a protectorate over Albania, annexed Fiume, and concluded the Lateran Pacts with the Catholic Church, securing broad domestic legitimacy and reshaping Italy's foreign posture.
Phase II: Zenith
During the mid-1930s, Fascist Italy reached its greatest imperial extent by conquering Ethiopia in 1935–1936, incorporating it into Italian East Africa alongside Eritrea and Somaliland. Italy also formally annexed Albania in 1939 and signed the Pact of Steel with Nazi Germany. Domestically, the regime pursued economic modernization and autarky, while Mussolini projected Italy as the heir to Roman imperial power.
Phase III: Decline
Entering World War II in 1940, Italian forces suffered repeated setbacks in North Africa, Greece, and the Eastern Front. Following the Allied invasion of Sicily in July 1943, King Victor Emmanuel III had Mussolini arrested. Italy signed an armistice in September 1943; Germany then occupied the north and installed Mussolini as head of the puppet Italian Social Republic. Mussolini was killed by partisans on 28 April 1945, ending Fascist rule.
