--- - |2 Abstract Grounded in institutional isomorphism theory, the paper analyzes the extent to which the process of homogenization (isomorphism) can be useful in our understanding of changes within religious entities. Examining the emergence and development of religious entities in post‐Soviet Tajikistan, I find that three isomorphic mechanisms are less dependent on the impact of religious institutional environments and interaction among religious organizations. Rather, isomorphic changes are manifested as the result of interaction with the state. Mimetic and normative processes are observed in a weak state, whereas coercive isomorphism is exerted under the influence of a strong state. A relative heterogeneity of the religious field is observed in the first two stages of the development of religious entities. Once the state expands its regulation and control, religious entities become more homogeneous in structure and administration due to coercive isomorphism. Implications for extending the concept of institutional isomorphism beyond traditional organizational fields are discussed. - 'Journal of Historical Sociology, Volume 31, Issue 3, Page 346-362, September 2018.
