The discussion on the relevance of the “inclusion-moderation” thesis to Islamist parties has always been very stimulating. The rise of the Justice and Development Party (AKP, Adalet ve Kalkınma Partisi) in Turkey has so far attracted the attention of the international community in a period riven with the intensification of a civilizational discourse on a global scale since the early 2000s. The main premise of the study is that the “inclusion-moderation” thesis is not very relevant for the Islamists in Turkey. Rather, an “exclusion-moderation” thesis has been more relevant for Islamists’ experiences since the 1960s. AKP was established in 2001 as an offspring of traditional oppositional political Islam in Turkey, which is renowned as the “National Outlook” movement. The name of the party very successfully addressed the two missing elements of the Turkish state and society: “justice” and “development.” The party came to power in 2002 in the aftermath of the one of the most devastating economic crises to hit the country: that of 2001. Starting with a very democratic, inclusive, cohesive, liberal, universalist, and fair political discourse, the party gradually became more and more anti-democratic, authoritarian, populist, polarizing, neo-Ottomanist, and Islamist, at the expense of liberal, secular, non-Sunni, non-Muslim, and other oppositional social groups. Election declarations (seçim beyannameleri) as well as the speeches of the party leaders will be discursively analyzed to find out whether there has been any behavioral moderation in the AKP before or after they came to power. The same documents and speeches will be scrutinized to understand whether there is ideological moderation in the party. The focus will be on the latter to detect the ways in which the AKP leadership has so far deployed an Islamist ideology, which has lately become coupled with a populist political style.
