The leader of the Communist Party during the Russian Revolution was Vladimir Lenin. He played a pivotal role in the Bolshevik Revolution of 1917, which overthrew the Provisional Government and established a communist regime in Russia. Lenin's leadership focused on the ideas of Marxism and aimed to create a proletarian state. He advocated for “peace, land, and bread,” appealing to the war-weary and impoverished masses. Following the revolution, Lenin led the new government and instituted significant changes, including land redistribution and the nationalization of industry, solidifying the Communist Party's power in Russia.
