The Civil Code of the Russian Federation (, frequently abbreviated 'ГК РФ') is the prime source of civil law for the Russian Federation. The Russian Civil Law system descended from Roman Law through Byzantine tradition. It was heavily influenced by German and Dutch norms in the 18th-19th centuries. Socialist-style modifications took place during the Soviet period (1922-1991) and Continental European Law influences since the 1990s. The Civil Code of the Russian Federation came into force in four parts. The first part, which deals with general provisions (i.e. defines sources, names legal entities etc.) was enacted by the State Duma in 1994 and entered into force in 1995.
