The Justice and Development Party (AKP), an Islamist and populist political party led by Turkish President Recep Tayyip Erdoğan, has increasingly incorporated what we term civilizational populism into its discourse. This article examines civilizational populism in AKP discourse, especially in the discourse of its leader Erdoğan, and finds it to be an important element of AKP discourse and ideology. The article also examines the impact of civilizational populism on Turkish domestic and foreign policy under AKP rule. The article finds that the AKP has increasingly, and especially since the 2013 Gezi Park protests and the mysterious coup attempt in 2016, construe opposition between the Turkish ‘self’ and the ‘other’ not in primarily nationalist terms, but in civilizational terms, and as a conflict between the Ottoman-Islamic ‘self’ and ‘Western’ other. Furthermore, the article finds that the AKP’s domestic and foreign policies reflect its civilizational populist division of Turkish society insofar as the party is attempting to raise a ‘pious generation’ that supports its Islamizing of Turkey society, and its neo-Ottoman imperialism in the Middle East. Finally, the paper discusses how the AKP’s civilizational populism has become a transnational phenomenon due to the party’s ability to produce successful televisions shows that reflect its anti-Western worldview and justify its neo-Ottoman imperialism in the Middle East.
