In the postmodern world, scientific, technological and cultural developments have significantly changed the impact of religion and led to radical changes in people's daily lives. Undoubtedly, this impact and the resulting transformation manifests itself in every field, especially in the education system. How has the Turkish education system, which has been governed by different practices in different periods, developed a perspective on religious values in the historical process? Moreover, how have the developments affecting the society in general shaped people's approach to religious institutions from an educational perspective? The Turkish education system, which is thought to be affected by the secularization process, defined as the decline in the influence of religion in modern societies, was analyzed by focusing on four different periods through research techniques such as literature review, document analysis and examination of educational policies. The research focuses on tracing the movement from the Turkish education system, which was historically influenced by religion and its cultural components, to today's Turkey, where the effects of modernization and secularization are felt. Accordingly, the article aims to examine the relationship between religious values and the Turkish Education System and analyze how this relationship has evolved over time in response to significant historical, social, cultural and political changes. In connection with this, the impact of religious values on the Turkish Education System throughout its historical development is examined, with a particular focus on the secularization process. All things considered, the importance of this paper lies in its examination of the evolving relationship between religious values and the Turkish Education System, which has been shaped by historical, cultural, social and political forces over time. In particular, the article provides valuable insights into how the secularization process, characterized by the diminishing role of religion in modern societies, has influenced educational policies and practices in Turkey.
