The third meeting of the All-Russian Congress of Soviets officially established the entity known as the Russian Soviet Federative Socialist Republic on the 25th of January 1918. This event followed the emergence of the Russian Soviet Republic on the 7th of November 1917 following the October Revolution.
Vladimir Lenin created the world's first communist government under his leadership after the October Revolution. Prominent members of the Left Socialist Revolutionaries assumed positions in Lenin's government including roles in agriculture, property, justice, post offices, telegraphs, and local government.
Just four months after Operation Barbarossa began the Wehrmacht advanced quickly through the Russian SFSR reaching approximately 100 kilometers from Moscow. German forces were pushed back after the defeat in the Battle of Moscow and a Soviet winter offensive ultimately pushing them out of Russia by 1944.
The Russian SFSR was composed of sixteen smaller constituent units including autonomous republics five autonomous oblasts ten autonomous okrugs six krais and forty oblasts. Turkestan ASSR formed on the 30th of April 1918 while Bashkir ASSR formed on the 23rd of March 1919 among other units.
On the 17th of March 1991 an all-Russian referendum created the post of President of RSFSR and on the 12th of June Boris Yeltsin was elected president by popular vote. He had been elected chairman of the Supreme Soviet of the Russian SFSR on the 29th of May 1990 at his third attempt.
