The leader of the Bolsheviks during the Russian Revolution was Vladimir Lenin. He played a pivotal role in the October Revolution of 1917, which led to the overthrow of the Provisional Government and established Bolshevik control over Russia. Lenin's leadership was crucial in articulating a vision for a socialist state, heavily influenced by Marxist ideology. His effective use of propaganda and the organization of the armed forces facilitated the Bolsheviks' rise to power. Following the revolution, Lenin became the head of government and implemented significant reforms, including land redistribution and the nationalization of industry, which laid the foundation for the Soviet Union.
