Islam and its history in Turkmenistan Islam came to the Turkmen primarily through the activities of Sufi shaykhs rather than through the mosque and the "high" written tradition of sedentary culture. These shaykhs were holy men critical in the process of reconciling Islamic beliefs with pre-Islamic belief systems; they often were adopted as "patron saints" of particular clans or tribal groups, thereby becoming their "founders." Reformulation of communal identity around such figures accounts for one of the highly localized developments of Islamic practice in Turkmenistan. Integrated within the Turkmen tribal structure is the "holy" tribe called övlat . Ethnographers consider the övlat, of which six are active, as a revitalized form of the ancestor cult injected with Sufism. According to their genealogies, each tribe descends from Muhammad through one of the Four Caliphs. Because of their belief in the sacred origin and spiritual powers of the övlat representatives, Turkmen accord these tribes a special, holy status. In the 18th and 19th centuries, the övlat tribes became dispersed in small, compact groups in Turkmenistan. They attended and conferred blessings on all important communal and life-cycle events, and also acted as mediators between clans and tribes. The institution of the övlat retains some authority today. Many of the Turkmen who are revered for their spiritual powers trace their lineage to an övlat, and it is not uncommon, especially in rural areas, for such individuals to be present at life-cycle and other communal celebrations.

For the most part, the Muslim Board functioned as an instrument of propaganda whose activities did little to enhance the Muslim cause. Atheist indoctrination stifled religious development and contributed to the isolation of the Turkmen from the international Muslim community. Some religious customs, such as Muslim burial and male circumcision, continued
