The document summarizes the February Revolution of 1917 in Petrograd that overthrew the Russian monarchy. It describes the harsh winter conditions that led to widespread strikes and protests. Demonstrations started at factories and spread throughout the city as workers marched down Nevsky Prospekt. No political party was organizing the movement initially. The revolution established a provisional government and soviets formed across Russia, though there was no common election system. Lenin returned from exile in April and published his April Theses calling for land redistribution, nationalization of banks, and renaming the Bolshevik party to the Communist party. The Bolsheviks seized power in October 1917 through the October Revolution and began nationalizing industry and land reforms.
