Russia golden ring historically building. A statue of a man wearing a suit and tie

Vladimir Lenin (1870–1924) was a founder of the Russian Communist Party (Bolsheviks), inspirer and leader of the Bolshevik Revolution (1917), and the architect, builder, and first head (1917–24) of the Soviet state. He was the founder of the organization known as Comintern (Communist International) and the posthumous source of “Leninism,” the doctrine codified and conjoined with Karl Marx’s works by Lenin’s successors to form Marxism-Leninism, which became the Communist worldview.
