The centenary of the creation of the International Committee on Intellectual Cooperation (ICIC) is an opportunity for historians to step back and examine the achievements but also the limitations of this enterprise, its lack of diversity and cultural representativeness. In recent years, there has been a renewed interest in this field of research, in parallel with a renewed interest in the League of Nations as a whole, in a context of doubts about the capacity of multilateral institutions. Without attempting to cover all the areas that remain to be studied in relation to intellectual cooperation and soft power diplomacy in the interwar period, such an event therefore seems to be a useful place of exchange at the crossroads between the archives, teaching and research communities.
