Local groups of the Russian ethnos at the end of the XIX-first quarter of the XX centuries : historical and demographic research

The paper deals with ethnic groups of the Russians of the late XIX- first quarter of the XX centuries. The author divides all local groups of the Russians into ethno-territorial, ethno-class, ethno-confessional and ethnographic ones. They were formed in the context of the development of territorial-economic and historical-cultural clusters: Southern and Central Russian, North Russian, Siberian, Far Eastern and Central Asian. Subethnic groups of the Russians had to adapt to different climatic conditions, perceive the way of life and a new type of economy, elements of the material culture of the aboriginal peoples. The degree of closeness to indigenous peoples varied. From self-isolation to close contacts and mixed marriages. At the same time, as a rule, the Russians retained their language, cultural elements, ethnic identity and other basic values. The paper presents demographic indicators of local groups of the Russians of the late XIX-first quarter of the XX centuries.
