This article provides a comprehensive framework to explain why Turkey has adopted a pro-active diaspora agenda since the early 2000s. It shows that Turkey's diaspora policy is the result of an amalgamation of domestic, transnational, and international factors: Domestically, the AKP's rise to power resulted in drastic economic and political reforms and the promotion of a new identity based on neo-Ottomanism and Sunni-Muslim nationalism. These developments have transformed Turkey's state-diaspora relations. The 2013 Gezi Park protests and the 2016 failed coup attempt also played a role. Transnationally, Turkish expatriates' growing socioeconomic and political clout in their host countries, as evidenced by the mushrooming of political parties founded by Turks in Europe, has urged Turkey to reconsider the efficacy of its diaspora as a source of influence abroad as well as a noteworthy electorate in national elections. Various international events have also shaped Turkey's new diaspora agenda, including Turkey's increasing bargaining power vis-à-vis the EU since the early 2000s, particularly after the European refugee crisis, and the rise of Islamophobia in the post-9/11 era. I suggest that domestic factors have played the most significant role in shaping Turkey's diaspora agenda. I examine the domestic dimension both as an independent factor and also in relation to transnational and international factors. The configuration of a new political elite has changed the ways in which Turkey interacts with its transnational diaspora and perceives its international position vis-à-vis European countries. The findings of the article draw on official statements and documents, semistructured in-depth interviews conducted with Turkish officials, the Euro-Turks Barometer Survey, and news sources.
