Russia's regions and republics with Muslim majorities (e.g. Tatarstan/Volga region; Daghestan/North Caucasus),  have traditionally been studied in isolation from each other, with the result that also the particular practices and concepts of Islam have been understood as "national". In recent years scholars and activists have established overarching cupola constructions like "Russian Islam", "Traditionalism" or "Islamic Eurasianism".
