What was Lenin known for in the context of the Russian Revolution?

Lenin is recognized as the founder of the Bolsheviks, a key political party that played a fundamental role in the Russian Revolution of 1917. Under his leadership, the Bolsheviks advocated for a proletarian revolution and aimed to establish a socialist state, which they achieved by seizing power from the provisional government in October 1917. Lenin's theories on Marxism and revolution influenced the Bolshevik strategy and their eventual triumph during the revolution. His leadership and ideology were critical in shaping the direction of the revolution and the subsequent formation of the Soviet state.

While other options mention significant aspects of the revolution, they do not accurately capture Lenin's role. The Mensheviks were a rival faction to the Bolsheviks, and Lenin's policies stood in stark contrast to the notion of establishing a democratic government as promoted by some other factions at the time. Additionally, while Lenin had his own wartime strategies, this option does not encapsulate his broader influence on the revolution as effectively as his founding role in the Bolsheviks does.
