On November 7, 1917, with the assault and looting of the Winter Palace, the October Revolution marked the end of the Russian Revolution and the birth of the Russian Soviet Socialist Federative Republic.
From the collapse of the Russian empire in March of the same year (February Revolution) and during the months of Kerensky's provisional government taking office in Kremlin, the revolutionary Bolsheviks, with Lenin and Trockij's Russian Social Democratic Workers' Party, succeeded in acquiring increasing power and consensus until they reached the aforementioned coup d'état.
Bearers of revolutionary Marxist ideologies and supporters of the working class struggle, Lenin and his followers brought hope to a country condemned by the economic crisis, by the war in the central empires, by the decline of Peter's, by the internal turmoil and defeats suffered in the First World War, until the end of the bloody Russian civil war between "red" (Bolsheviks) and "white" (counterrevolutionaries).
With the Revolution power was formally handed over to the Congress of Soviets, whose first main measures were: the distribution of land to farmers, restrictions on trade, the obligation to hand over crops to the authorities, up to the extreme measures taken subsequently and under the name of "communism of war".
The victory of the Bolshevik faction sanctioned the end of the civil war in 1922 and the consequent official birth of the Soviet Union; it played a fundamental role throughout the 20th century until its fall in December 1991.
