Karl Heinrich Marx (5 May 1818 – 14 March 1883) was a German political philosopher, economist, historian, sociologist, journalist and revolutionary socialist. Marx's work in economics laid the basis for labor theory of value, and has influenced much of subsequent economic thought. He published many works during his lifetime, including The Communist Manifesto (1848) and the first volume of Das Kapital (1867), the two later volumes being completed by his collaborator Friedrich Engels.
