Traditions and innovations in the life support system and spiritual culture of the Tatars in the zone of interethnic and ethnocultural interaction

The article presents the field materials of the 2022 summer ethnographic works in the Kachukovo and the Ust-Tamak villages in the Znamensky District, Omsk Region. Information collected in these villages in 2002 was used as comparative materials. The changes over twenty years have been analyzed: in economic activities aimed at food production and in rations. Local features and transformations are also described on the example of national cuisine. The paper considers examples of ethno-cultural ties between Tatars, Russians and Belarusians. The following conclusions were made: 1) at present, the population of these villages is a microgroup and a kind of enclave among the non-Tatar, mainly Slavic population; 2) there is a reduction in personal subsidiary farming (animal husbandry and gardening), a decrease in the importance of fishing; 3) in everyday and ceremonial dishes, the backbone of traditional technologies and dishes is preserved. The set of ritual dishes recorded in 2002 survives. There is an increase in the share of purchased food, a decrease in the role of homemade dairy products, a decrease in the amount of fish consumed, canned vegetables, a decrease in the use of lamb for ritual dishes; all these are examples of transformation since the first survey; 4) The specificity of the microgroup is the intermarital relations and ethno-cultural contacts with the Slavic residents of these villages, as a result of which new customs and habits were formed among the Tatars (celebration of the Easter holiday, participation in the rites of the funeral and memorial cycle, and others).
