Karl Heinrich Marx (1818 – 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist and socialist revolutionary. Born in Germany, Marx studied law and philosophy at university. His best-known titles are the 1848 pamphlet The Communist Manifesto and the three-volume Das Kapital (1867–1883). Marx's political and philosophical thought had enormous influence on subsequent intellectual, economic and political history.
