The leader of the Bolshevik Revolution, which occurred in 1917, was Vladimir Lenin. As the head of the Bolshevik Party, Lenin played a crucial role in overthrowing the provisional government that had been established after the abdication of Tsar Nicholas II. Advocating for "peace, land, and bread," Lenin's ideas resonated with the working class and soldiers disillusioned by World War I. His leadership during the October Revolution led to the establishment of a socialist state in Russia, eventually resulting in the formation of the Soviet Union. Lenin remains a central figure in discussions about revolutionary theory and practice.
