Final answer:
The Bolshevik Revolution occurred in 1917 and was a key part of the larger Russian Revolution. It resulted in the overthrow of the provisional government by the Bolsheviks led by Lenin, who then established a socialist government.
Step-by-step explanation:
The Bolshevik Revolution, a significant historical event, happened in 1917. This revolutionary wave was a part of the broader Russian Revolution that began during the same year. Tsar Nicholas II's inability to address Russia’s deep-rooted issues, exacerbated by the hardships and the tremendous losses incurred during World War I, led to his abdication. Following the abdication, a provisional government briefly took power but was quickly overthrown by the Bolsheviks, led by Vladimir Lenin. The Bolsheviks, inspired by Marxist beliefs, established a socialist government and withdrew Russia from the war through an armistice with Germany. The revolution set the stage for a radical transformation of Russian politics and society. The Bolshevik Revolution, also known as the October Revolution, took place in 1917. It marked the overthrow of the Provisional Government and the establishment of Soviet power in Russia. The Bolsheviks, led by Vladimir Lenin, played a key role in this event, which eventually led to the formation of the Soviet Union.
