This article focuses on the historically complex relations between the Presidency of Religious Affairs (Diyanet) and the Turkish state. It asserts that the Diyanet, from its establishment in 1924 to the present time, has experienced transformation from a strictly state-controlled institution to a more autonomous one. This transformational process transpired, sometimes overtly and sometimes covertly, within the borders of the secular state. In exploring this process, the article analyzes the ways in which the institution’s position has gradually risen within the state’s constitution and how its religious discourses, statements, and activities have changed from nationalistic to holistic.
