Karl Marx (German: [kaʁl ˈmaʁks]; 5 May 1818 – 14 March 1883) was a German-born philosopher, political theorist, economist, historian, sociologist, journalist, and revolutionary socialist. His best-known works are the 1848 pamphlet The Communist Manifesto (with Friedrich Engels) and his three-volume Das Kapital (1867–1894); the latter employs his critical approach of historical materialism in an analysis of capitalism, in the culmination of his intellectual endeavours.
