Imperialism, colonialism and irredentism played an important role in the foreign policy of Fascist Italy. Among the regime's goals were the acquisition of territory considered historically Italian in France (e.g. Nice) and Yugoslavia (e.g. Dalmatia), the expansion of Italy's sphere of influence into the Balkans (e.g. Greece) and the acquisition of more colonies in Africa. The pacification of Libya (1923–32), the invasion of Ethiopia (1935–36), the invasion of Albania (1939), the invasion of France (1940), the invasion of Greece (1940–41) and the invasion of Yugoslavia (1941) were all undertaken in part to add to Italy's national space. According to historian Patrick Bernhard, Fascist Italian imperialism under Benito Mussolini, particularly in Africa, served as a model for the much more famous expansionism of Nazi Germany in Eastern Europe.
