Chatham House had been researching potential post-war issues as early as 1939 through the Committee on Reconstruction. Whilst a number of staff returned to the Institute at the end of the war, a proportion of members found themselves joining a range of international organisations, including the United Nations and the International Monetary Fund. Combining this with the Institute's early support of the League of Nations and impact of the gold study on the Bretton Woods system, Chatham House found itself to be a leading actor in international political and economic redevelopment.
