The study provides an analysis of the evolution of state religious policy in Kazakhstan, with special emphasis on an integrated approach that combines strategic guidelines with practical measures aimed at promoting religious harmony and strengthening national security. A detailed analysis of the legal, administrative, and practical aspects of interaction between the state and religious institutions is conducted, emphasizing the critical importance of preserving the secular model of governance that promotes freedom of conscience, religious tolerance, and the prevention of interreligious conflicts. A comprehensive review of existing literature, combined with empirical data collected from various governmental and non-governmental sources, as well as a comparative analysis of the practices of other secular states, reveals significant public support for the current religious policy. However, the study also identifies key challenges facing Kazakhstan, such as the growing threat of religious extremism, demographic pressures, and the need to update the legal framework. The main findings of the work emphasize the need to develop a holistic concept of state policy in the religious sphere, including legal, methodological, and organizational measures that will effectively manage religious diversity in the country. The conclusion presents strategic recommendations aimed at further improving Kazakhstan’s religious policy, which will contribute to strengthening socio-political stability and ensuring a balanced, progressive approach to religious issues in the context of modern challenges of globalization and regional changes.
