and around the port city of Derbent, the population (primarily made up of Azerbaijanis) is Shia. A Salafi minority is also present, which is often a target of official repression. The appearance of Sufi mysticism in Dagestan dates back to the 14th century. The two Sufi orders that are widely spread in the North Caucasus were the Naqshbandiya and the Qadiriya. The mystic tariqas preached tolerance and coexistence between the diverse people in the region. The Communist total intolerance for any religion after the Communist Revolution of 1917 also suppressed the Sufi movements. Shaykh Said Afandi al-Chirkawi was a prominent scholar, spiritual leader, and murshid (guide) of Naqshbandi and Shadhili tariqahs in Dagestan until his death. Since the dissolution of the Soviet Union, there has been an Islamic revival in the region. By 1996, Dagestan had 1,670 registered mosques, nine Islamic universities, 25 madrassas, 670 maktab, and it is estimated that "nearly one in five Dagestanis was involved in Islamic education", while of the 20,000 or so Russian pilgrims for the Hajj more than half were from Dagestan. Judaism A relatively large number of native Tati-speaking Jews – the "Mountain Jews" – were also present in these same coastal areas. However, since 1991 and the collapse of the Soviet Union, many have migrated to Israel and the United States. These were an extension of much larger Azerbaijani Jewish community across the border in the Azerbaijani districts of Quba and Shamakhi. Christianity The number of Christians among the non-Slavic indigenous population is very low, with estimates between 2,000 and 2,500. Most of these are Pentecostal Christians from the Lak ethnicity. The largest congregation is Osanna Evangelical Christian Church (Pentecostal) in Makhachkala, with more than 1,000 members. Cathedral of the Assumption is an Eastern Orthodox cathedral located in the city of Makhachkala, the main cathedral of the Diocese of Makhachkala. Church of the Holy Equal-to-the-Apostles Prince Vladimir is a Russian Orthodox cathedral of the Diocese of Makhachkala, located in the city of Makhachkala. Genetics In 2006, a genetic study of the Dagestan populations, published in Human Biology, suggested that inhabitants of Dagestan are closely related to Anatolian Turks and Cypriot Turks. Yunusbayev et al. pointed out that these findings support the theory that indigenous groups of Dagestan can trace their roots back to ancient Anatolian farming tribes who introduced early agricultural traditions.
