The article is devoted to studying the features of the traditional culture of the descendants of Belarusian immigrants of the second half of the XIX - early XX centuries living in Western Siberia. Based on the materials of expedition studies in places of their compact residence, the nature of ethno-cultural interactions between migrants and the old-time environment is considered, and the main markers of the ethno-cultural identity of Belarusians in Siberia are highlighted. A detailed description is given of the "Candle" rite recorded among the displaced people, which is common in the places of their release in the territory of Mogilev Province. Based on the generalization of the research results, conclusions are drawn about the correlation between the principles of settlement of Belarusians in Siberia and the peculiarities of their ethno-cultural self-identification in a new place. Key words: Belarusians in Siberia, traditional culture of Belarusians, peasant migrations, ethno-cultural interactions.

This was largely due to the long-prevailing ideas about the insufficiently developed national identity of immigrants, the blurring of ethno-cultural differences between Belarusians and Siberian old-timers. Indeed, during the formation of places of compact residence of Belarusians on the territory of Siberia, the national consciousness of the majority of migrants was not yet fully formed, as evidenced by the phenomenon of "tuteishiny": "If you ask such Belarusians who they are in terms of nationality, then very many will only be able to tell you that they are" tuteyshe", i.e. local ones... And they will be rather skeptical about your claim that they are Russians or Belarusians: call them whatever you wan ... Read more
