SHEZHIRE OF THE GENUS ESTEK BY GENONYMY AND TRANSIT OF ETHNICITY ISHTYAK / ESTEK IN THE KAZAKH SOCIETY OF THE 18TH-19TH CENTURIES

The article deals with the legends of the family of Estek about the events and rituals of integration into the Kazakh community of the 18th century, which can be used to understand the medieval markers of Estek, Ishtyak, Estek, Ostyak, Heshdek as genonyms. There is an extensive and controversial historiography regarding the designations of these concepts, which is explained by differences in sources and methodological preferences. To resolve the contradictions between the Ugric and Turkic etymology of the concepts, various ideas were proposed, including the constructivist interpretation of the yasak subjects in the Urals and Siberia as a socionym. This is indicative of the perception of the yasak estate by the tsarist administrators, but does not exclude the ethnic content of the markers, if we turn to the authentic evidence of the Turkic historical memory.
