By the outbreak of World War I in 1914, Italy had annexed Eritrea and Somalia, and had wrested control of portions of the Ottoman Empire, including Libya, though it was defeated in its attempt to conquer Ethiopia. The Fascist regime under Italian dictator Benito Mussolini which came to power in 1922 sought to increase the size of the empire further. Ethiopia was successfully taken, four decades after the previous failure, and Italy's European borders were expanded.
