After the failure of the Stresa agreements and the condemnation of the international community for the occupation of Ethiopia, Mussolini came closer and closer to Hitler. The two regimes consolidate the agreement by sending a contingent of militiamen to support the Phalangists in Spain, to overthrow the legitimately elected Left government. The Spanish War becomes the clash between democracies and fascism and is considered the rehearsal of the Second World War. Inspired by the alliance of left-wing parties in the Popular Front (Communists, Socialists, Social Democrats), active since the mid-1930s, the Popular Front was born, with the aim of fighting international fascism. During the Civil War, More than 30,000 volunteers from the International Brigades from more than 50 countries will arrive in Spain.
