The history of the creation of the United Nations Educational, Scientific and Cultural Organization (UNESCO) encompasses essentially two international conferences: the Conference of Ministers of Education of the Allied Governments and the French National Committee (CAME) which took pJace in London from 1942 through 1945 and the Conference of the United Nations for the Establishment of an International Organization for Education and Culture, held November 1–16, 1945. The latter conference, called jointly by the governments of France and the United King dom, was partially a result of the former and was also held in London. At this two-week conference UNESCO's constitution was drafted and adopted. In this development a part was played by the founding process of the United Nations whose Charter, adopted at the United Nations Conference on International Organization in San Francisco in June 1945, foresaw the advancement of international cooperation in culture and education. The founding conference of UNESCO considered itself the executor of this mandate. This article will show how the idea of international cultural cooperation was developed during the Second World War at the meetings of CAME, how it was modified by the United States aid policy toward Europe, how it was influenced by French traditions of intellectual cooperation manifested within the framework of the League of Nations, and how it led finally to the creation of a new specialized agency of the United Nations.
