Making clear definitions about the phenomena that shape social reality becomes difficult in sociological evaluations of human societies. Religion is one of these phenomena. The phenomenon of religion always maintains its existence for a visible and collectively covered demand, together with traditional or mystical belief codes. Throughout history, religion has had a privileged place and position in the lives of Turks. The Turks believed that in the transience of worldly life, the journey of death and bodily annihilation began, and that there was no such annihilation for the human spirit. Therefore, in the culture of Turks, the temporality of the investment in the body and the permanence of the investment in the soul are unchangeable. This process, called traditionalization, is essentially a re-expression of the change in the social actor in question in the history of the Turks. It is seen that various studies and trials have been carried out on the religious history of the Turks until today. However, studies that show a scientific and systematic approach have not yet touched on the subject in its objective and modern sense. In this study, based on the literature review, first of all, the social reality of religion will be focused on due to the need in question. Then, the religious history of the Turks will be examined in the context of pre- Islamism, post- Islamism and Republic period developments.
