The Constitution of the Russian Federation (Russian: Конституция Российской Федерации, romanized: Konstitutsiya Rossiyskoy Federatsii) was adopted by national referendum on 12 December 1993 and enacted on 25 December 1993. The latest significant reform occurred in 2020, marked by extensive amendments that altered various sections, including presidential terms, social policies, and the role of Russian law over international ones. (See 2020 amendments to the Constitution of Russia).
Russia's constitution came into force on 25 December 1993, at the moment of its official publication, and abolished the Soviet system of government. The 1993 Constitution is one of the longest-standing constitutions in Russian history, second only to the Soviet Union’s 1936 Constitution, which was in effect until 1977.
