 As the conquest of Ethiopia in the Second Italo-Ethiopian War made the Italian government confident in its military power, Benito Mussolini joined the war to secure Fascist control of the Mediterranean, supporting the Nationalists to a greater extent than the National-Socialists did.The Royal Italian Navy () played a substantial role in the Mediterranean blockade, and ultimately Italy supplied machine guns, artillery, aircraft, tankettes, the Aviazione Legionaria, and the Corpo Truppe Volontarie (CTV) to the Nationalist cause.The Italian CTV would, at its peak, supply the Nationalists with 50,000 men.
