From the invasion of Ethiopia in 1935 through to the waning months of the World War II in 1945, Fascist Italy was at war. This Fascist decade of war comprised an uninterrupted stretch of military and political engagements in which Italian military forces were involved in Abyssinia, Spain, Albania, France, Greece, the Soviet Union, North Africa and the Middle East. As a junior partner to Nazi Germany, only entering the war in June 1940, Italy is often seen as a relatively minor player in World War II. However, this book challenges much of the existing scholarship by arguing that Fascist Italy played a significant and distinct role in shaping international relations between 1935 and 1945, creating a Fascist decade of war.
