The leader of the Bolshevik Revolution in Russia was Vladimir Lenin. An influential Marxist theorist and revolutionary politician, Lenin played a pivotal role in overthrowing the Provisional Government during the October Revolution of 1917. His leadership was characterized by the promise of "peace, land, and bread," which resonated with the war-weary and economically struggling populace. Following the revolution, Lenin established a one-party socialist state, leading to the formation of the Soviet Union. His vision and policies fundamentally transformed Russia's political landscape and had far-reaching consequences for global politics throughout the 20th century.
