In April 1967, a group of colonels seized power in Greece. Since Greece was a member-state of the Council of Europe and held an association agreement with the European Community, both organizations had to define their positions vis-à-vis the new military regime. Very soon, politicians in the parliamentary assemblies of both organizations started to cooperate with the aim of imposing sanctions on Greece. This article examines the inter-organizational dynamics between the European Community and the Council of Europe on Greece during the colonels’ regime. It argues that the European Community imported concrete policy positions and even normative ideas which had first emerged in the Council of Europe. In so doing, the Community prepared the ground for its future human-rights policies.
