This paper introduces mukaddesatçılık as a Cold War ideological position that reconciles Turkish nationalism, religious conservatism, and Islamist revivalism. Mukaddesatçılık channels senses of disempowerment and alienation among people with Islamic and nationalistic sensibilities to a sense of ressentiment against the Turkish modernization process. The paper analyzes mukaddesatçılık's ideational and emotional components based on the writings of Necip Fazıl Kısakürek. In addition to being the name-father of the concept, Kısakürek was distinguished from other Islam-inspired conservative intellectuals by his appeal to popular mobilization around mukaddesatçı ideology through his eloquent and powerful speeches and poems. The paper argues that Kısakürek's mukaddesatçılık reconstructed Muslimness as the political identity of the popular masses, who are the supposed victims of the Turkish modernization process, to mobilize them against the so-called Western-minded modernizing elite. Mukaddesatçılık informs the current populist policies of Recep Tayyip Erdoğan's government that seek to maintain the divisive polarization between religious and secular identities.
