During the early post-war years Britain occupied an indeterminate position within the international system. Although one of the 'Big Three' victorious allies, it did not possess the resources of the US and the USSR. Nor did it share the wartime experience of occupation, division and defeat of many continental European states. The documents in this section reflect the impact of these and other conditions on the evolution of British policy towards the idea of European unity during the period of post-war reconstruction.
