Аннотация:This chapter, based on archival documents and testimonies, examines the funeral-memorial rituals of a Moscow Tatar community, most of which originated from the Gorkiy (Nizhnii Novgorod) region, during the period of “mature socialism” in the 1960s–1980s. The focus is on the activity of the only Muslim temple open in Moscow at the time, the Cathedral Mosque, which was then headed by imam Akhmetzian Mustafin, and of representatives of the unofficial clergy conducting funeral and memorial rituals. The active participation of women in these rituals is also examined more closely. This research shows that Tatars, unlike other ethnic groups, including Russians, continued to strictly observe traditional memorial-funeral rituals throughout the Soviet period, even within the numerically small and quite secular Tatar communities of large cities. It also testifies to the fact that, in spite of widespread stereotypes about an opposition between the official and unofficial clergy, in the Soviet period they often de facto collaborated. This was the case not particularly in the sphere of funeral-memorial rituals, but also in the conservation, albeit in a limited form, of religious tradition, on the basis of which a revival of Islam occurred in the late 1980s.
