Abstract. Religious security became one of the important spheres in internal and external political affairs of the post-Soviet Muslim countries during 30 years of their independent development. Each of these states, including Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan,  gained their own experience in solving  problems of religious security which however had many common features and methods of fighting religious extremism and radicalism. As a result it allowed the above countries to form cooperation in this field during  the last decade and to undertake a lot of common practical and legal interstate steps in order to provide their  religious security.
