The Europeanization of national foreign policy: explaining Greek support for Turkey’s EU accession

Europeanization has been a fashionable term over the last decade. However, when it comes to foreign policy, extant work has produced inconsistent findings and few theoretical insights. This paper aims to fill this gap by constructing a synthetic theory which integrates into a ‘thick rationalist’ approach four mechanisms of Europeanization identified in the literature (policy adaptation, normative framing, differential empowerment, diplomatic coordination), and specifies a set of mediating conditions that can explain variations in the scope and direction of Europeanization. This theory is used in order to explain why Greece has become, since 1999, an active and solid supporter of Turkey’s European Union (EU) membership prospect.
