The Communist Party during the Russian Revolution was led by Vladimir Lenin. He played a crucial role in orchestrating the October Revolution of 1917, which overthrew the provisional government established after the earlier February Revolution. Lenin's leadership was marked by his commitment to Marxist ideology, advocating for a proletarian revolution. He implemented the Bolshevik program that promised "peace, land, and bread," addressing the immediate needs of the war-torn Russian populace. Lenin's leadership ultimately established the Soviet regime, transforming Russia into a one-party state ruled by the Communist Party, which significantly influenced global politics throughout the 20th century.
