Abstract
The article gives the results of the statistic analysis of interethnic marriages in the Udmurt ASSR in the 1930s. The author considers the marriages of the largest nations of the republic and the share of the interethnic marriages. There were analyzed marriages among Russians, Udmurts and Tatars living in the cities and rural areas of the Udmurt ASSR. As for Mari and Chuvash, the information is sketchy, so it is hard to make any conclusions on inter-ethnic marriages among them. The situation with interethnic marriages in the 1930s is compared with that in the previous decade. The conclusion is that while in the 1920s the process of assimilation in the republic was not very active, by the end of the 1930s the situation had changed, as evidenced by the frequent interethnic marriages. The variants of combinations of nationalities show that the most active assimilation processes followed the line of the «Udmurt man - Russian woman». The article is written on the basis of previously unpublished materials.
