Muslims constitute the nationalities in the North Caucasus residing between the Black Sea and the Caspian Sea: Adyghe, Balkars, Chechens, Circassians, Ingush, Kabardin, Karachay, and numerous Dagestani peoples. Also, in the middle of the Volga Basin reside populations of Tatars and Bashkirs, the vast majority of whom are Muslims. Islam is considered as one of Russia’s traditional religions, legally a part of Russian historical heritage. There are over 5,000 registered religious Muslim organizations (divided into Sunni, Shia and Sufi groups), which is only one sixth of the number of registered Russian Orthodox religious organizations of about 29,268 (As of December 2006).
