The Russian Revolution overthrew the Czar's government in 1917 and established communist rule. It happened due to a weak ruler, poor living conditions for workers and peasants, and Russia's poor performance in WWI. There were two revolutions - in February 1917, the Czar abdicated and a provisional government took over, and in October 1917 the Bolsheviks led by Lenin seized power. Lenin immediately pulled Russia out of WWI and proposed distributing land to peasants. He established communist party rule, forming the USSR, before Stalin took control after Lenin's death in 1924.
