Tatarstan and Chechnya, two federal republics with strong Islamic elements in their regional identities, have nimbly positioned themselves within the “Russian world,” an ideological concept that has increased in prominence since the outbreak of the Ukraine conflict. Both republics have sought to raise their visibility within the Russian Federation and promote themselves as regional success stories, but their policies differ in many respects. Tatarstan promotes itself as a region where Islam and Orthodox Christianity harmoniously coexist, while the republic’s leadership avoids overt political or ideological agendas in pursuit of federal resources for regional development. Chechnya, on the other hand, has been a republic of extremes: President Ramzan Kadyrov has fostered a resurgent fundamentalist Islam and vigorously defended his region’s autonomy, all the while playing the role of stalwart defender of the Putin regime and—paradoxically—of the “Russian world” as its ideological core.
