ABSTRACT The process of Europeanisation initiated in Turkey following the 1999 Helsinki summit witnessed a loosening of state control over the Patriarchate of Constantinople under the government of the Justice and Development Party (AKP). In parallel with the AKP’s reforms geared towards EU membership, the Patriarchate’s activities became more transnational in their character, especially with regards to its organisation and influence over religious affairs within the Christian world. This contribution traces change and continuity in Turkish policy towards the Patriarchate under the AKP government. Key differences between the AKP government’s stance on the Patriarchate and those of its predecessors are noted, with specific reference to prospects of EU membership and the strategy that has been devised by the AKP to that end. Specifically, the contribution shows that Turkey’s bid to join the EU initially presented important leverage over Turkey, allowing the Patriarchate to reassert its transnational character. However, diminished prospects of EU membership together with a gradual return of nationalist sentiment now present an important challenge for the Patriarchate in its efforts to maintain transnational character and influence.
