György Lukács (born 13 April 1885 – 4 June 1971) was a Hungarian Marxist philosopher, aesthetician, literary historian, and critic.
He was one of the founders of Western Marxism, an interpretive tradition that departed from the Marxist ideological orthodoxy of the Soviet Union.
He developed the theory of reification, and contributed to Marxist theory with developments of Karl Marx's theory of class consciousness.
He was also a philosopher of Leninism. He ideologically developed and organised Lenin's pragmatic revolutionary practices into the formal philosophy of vanguard-party revolution.
