Marx
Karl Marx (German: maʁks; 5 May 1818 – 14 March 1883) was a German-born philosopher, economist, political theorist, historian, sociologist, journalist, and revolutionary socialist. His best-known works are the 1848 pamphlet The Communist Manifesto (with Friedrich Engels) and the three-volume Das Kapital (1867–1894); the latter employs his theory of historical materialism in an analysis of capitalism, representing his greatest intellectual achievement. Marx’s ideas, theories, and their subsequent development, collectively known as Marxism, have exerted enormous influence on modern intellectual, economic, and political history.
