Abstract: The subject of the research is the process and dynamics of creation of the civil law system in Russia over 1649 - 1675. The Sobornoye Ulozheniye of 1649 and following legal acts regulating civil law relations till 1675 have been selected by the researcher as the main sources to be studied in this historical legal research. The purpose of the research is to carry out a comprehensive historical legal research of the patterns according to which the civil law system had been creating in Russia over 1649 - 1675 as the part of the process of systematization of the effective legislation in general and civil law in particular. The methodological grounds for the research involve the dialectical, logical, systems, historical, comparative and technical (legalistic) research methods. The novelty of the research is caused by the fact that pre-revolutionary, Soviet and contemporary academic literature on legislative history have never before focused on the changes in statutory and substantive aspects of the Russian civil law during 1649 - 1675. Isolated legislative enactments contained legal rules and regulations contributed to the legal institutions of Ius in re (real right), inheritance rights and contractual rights that had been previously fixed in the Sobornoye Ulozheniye of 1649.
