Historical Trajectory
Phase I: Rise
Italy began acquiring overseas territories in 1882, establishing footholds in Eritrea and later Somalia. After the humiliation at Adwa in 1896, Italian colonial ambitions continued, culminating in the seizure of Libya from the Ottoman Empire in 1911–1912. The Fascist regime under Benito Mussolini, coming to power in 1922, aggressively pursued further expansion to forge a new Roman Empire and satisfy irredentist demands.
Phase II: Zenith
The empire reached its greatest extent between 1936 and 1941, following Italy's brutal conquest of Ethiopia in 1935–1936, which was merged with Eritrea and Somalia into Africa Orientale Italiana. Italy also controlled Albania and the Dodecanese Islands. The Fascist government promoted mass demographic colonisation, resettling hundreds of thousands of Italian settlers across Libya and East Africa to assert dominance over these territories.
Phase III: Decline
Italy's entry into World War II alongside Nazi Germany in 1940 initially brought temporary occupations of British Somaliland and parts of Egypt, Greece, Yugoslavia, and France. Allied counteroffensives expelled Italian forces from East Africa by 1941 and North Africa by 1943. Italy formally relinquished its colonial claims in 1947. Former Italian Somaliland was administered as a UN trust territory until Somali independence in 1960, marking the empire's final end.
