The Russian Soviet Federative Socialist Republic (Russian: Росси́йская Сове́тская Федерати́вная Социалисти́ческая Респу́блика [РСФСР] Rossiyskaya Sovetskaya Federativnaya Sotsialisticheskaya Respublika [RSFSR]), also called the Russian Soviet Federated Socialist Republic, the Russian SFSR and the RSFSR for short, was the largest and most populous of the fifteen Soviet republics of the Soviet Union and became the Russian Federation after the collapse of the Soviet Union. It was by far the largest sub-national entity in the world by area and 2nd in population after Uttar Pradesh, India. After the dissolution of the Soviet Union, Sichuan, China became the 2nd most populous subnational entity until 1997 when it was divided. The capital was Moscow, also the capital of the Soviet Union.
The Soviet regime was established on November 7, 1917, following the October Revolution. In Russian official documents of the time it was referred to as Russian Republic, Soviet Republic, (Russian: Советская Республика, or Russian Soviet Republic, among others. On July 10 1918 the 1918 Constitution was accepted, with the official name of Russian Socialist Federative Soviet Republic; the most recent variant of the name (with "Socialist" and "Soviet" swapped), was adopted in the 1937 Constitution.
In English, the term Bolshevist Russia or Soviet Russia is commonly used for the period 1917 - 1922.
The RSFSR became part of the Soviet Union in 1922, an act formalised by the 1924 Soviet Constitution.
On April 17, 1946 the Kaliningrad Oblast - the north of the former German province of East Prussia - was erected and made part of the Russian SFSR. Nikita Khrushchev transferred Crimea from the Russian SFSR to the Ukrainian SSR in 1954.
