The appearance of Sufi mysticism in Dagestan dates back to the 14th century. The two Sufi tariqas that 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 of Naqshbandi and Shadhili tariqahs in Dagestan until his death.
