British committee on the theory of international politics
The British Committee on the Theory of International Politics was a group of scholars created in 1959 under the chairmanship of the Cambridge historian Herbert Butterfield, with financial aid from the Rockefeller Foundation, that met periodically in Cambridge, Oxford, London and Brighton to discuss the principal problems and a range of aspects of the theory and history of international relations. The Committee developed a study of international society and the nature of world politics, which have had an important impact that continues in the present day.
Under the guidance of Herbert Butterfield, Martin Wight, Adam Watson and Hedley Bull, the British Committee on the Theory of International Politics met three times a year for an almost thirty-year period from the 1950s to the 1980s, once or twice in Italy. In 1974 a three days meeting (27-30 September) was held at Villa Serbelloni, Bellagio, in agreement with Rockefeller foundation.
They produced books, essays, article, and they regularly wrote a series of papers specially conceived for the Committee which provoked lively internal discussions and most of which are still unpublished.

- It has often been remarked upon, with some irony, that many of the leading lights in the formative era of the English school of International Relations were not English. This tendency show no signs of abating. (…) The most detailed book to be written on the British Committee – the institution that many regard as the fulcrum of the English School – has been written by Brunello Vigezzi from the University of Milan. (...) No better and more comprehensive account of their work [the British Committee ] is ever likely to be produced; Tim Dunne, Review of The British Committee on the Theory of International Politics 1954-1985: The Rediscovery of History, International History Review, XXIX:4, 2007, 913-14.
