Franco-Italian rivalry in the Mediterranean generally affected the dialogue
between European great powers. The dispute between Rome and Paris over the
North African colonies (and in particular Tunis, Tangier and Libya) cast a
shadow over negotiations in Europe concerning a settlement of the Rhineland
question. In 1925 Britain, France, Germany, Italy and Belgium became
involved in attempting to reach a permanent diplomatic solution over the
legacy of the peace accords that had followed the First World War. With the
Locarno Treaty the signatory states reached agreement over the status of the
Rhineland region and Alsace-Lorraine; the treaty also provided mutual security
guarantees for both Germany and France, with Italy and Britain as the guaranteeing
powers. For a more thorough examination of the impact of Franco-
Italian tensions over the Locarno negotiations, see H. J. Burgwyn, Italian
Foreign Policy in the Interwar Period, 1918–1940 (Westport, Conn.: Praeger,
1997), pp. 27–32. On the development of Franco-Italian diplomatic and military
relations during the second half of 1930s, see also R. J. Young, ‘French
