Relations internationales 166 (July 2016).
This article highlights and explains the turn of 1955 in the changing interaction pattern among the States of post-war Europe in the migratory field. This study calls into question the findings of previous works, by identifying this turn and its underlying forces. This work resorts to the documents of international organizations involved in these episodes: the Organisation for European Economic Cooperation, the Council of Europe, the European Coal and Steel Community and the European Economic Community. It also resorts to the archives of the French and West German governments. While previous studies had highlighted the role of the Italian strategy, this article explains the change primarily by describing the strategy of the German government related to the context of the Cold War.
