Muslim Slavs or Slavic Muslims are ethnic groups or sub-ethnic groups of Slavs who are followers of Islam. The term is most often used in the study of the Balkans, Southeastern Europe, Caucasus, Crimea, and Volga region. The majority of Slavic Muslims are found in Bosnia and Herzegovina, Albania, Kosovo, Montenegro, Bulgaria, and some republics of Russia. Slavic Muslims can also be found in southern Serbia and North Macedonia. Slavic Muslims are one among the indigenous ethnic groups who are native Europeans of the Islamic faith; the others are the Muslim populations of Albanians, Greeks, Romani, Balkan Turks, Pomaks, Yörüks, Volga Tatars, and Crimean Tatars, unlike the Muslims in Western Europe which are mostly non-European recent immigrants or the descendants of old immigrants.
