The British Committee on the Theory of International Politics is generally considered the original core of the “English School.” Equally often, scholars have identified as one of its characteristic elements the importance it attributed to “international society” as a force aimed at enlivening and regulating, as far as possible, power relations between states. The attention it paid to international society is also seen as consistent with the importance the authors of the British Committee attributed to “history” and in particular to the “history of international society” as a means to understand and reconstruct international life in the past and the present. However, the internal history of the British Committee is all too often neglected. Studies concerned with the orientations of the English School have mainly sought to analyze the thinking of this or that author without considering the work of the British Committee as a whole. In other words, scholars have tended to pay little attention to the moment when the British Committee began to examine “international society” and the manner in which it did so. In particular, the achievement of the British Committee discussions during 1961–1962 was important, and it was the beginning of a development of great interest. The various texts, the debates, do not limit themselves to a sort of rich and varied list of the component parts of an “international society.” Instead, they paint an overall picture, and they guarantee an interconnection between the reflections of the individuals and the overall orientation of the Committee. Moreover, they are the critical point of departure for the future development of theory.
