Karl Heinrich Marx (May 5, 1818–March 14, 1883) was a German-Jewish philosopher, political economist, sociologist, humanist, political theorist, revolutionary, and communist icon.

Marx's approach to history and politics is indicated by the opening line of the first chapter of The Communist Manifesto (1848): “The history of all hitherto existing society is the history of class struggles”. Marx argued that capitalism, like previous socioeconomic systems, will produce internal tensions which will lead to its destruction. Just as capitalism replaced feudalism, capitalism itself will be displaced by communism, a classless society which emerges after a transitional period—socialism—in which the state would be nothing else but the revolutionary dictatorship of the proletariat.

On the one hand, Marx argued for a systemic understanding of socioeconomic change. On this model, it is the structural contradictions within capitalism which necessitate its end, giving way to communism:

On the other hand, Marx argued that socioeconomic change occurred through organized revolutionary action. On this model, capitalism will end through the organized actions of an international working class, led by a Communist Party: "Communism is for us not a state of affairs which is to be established, an ideal to which reality 1 have to adjust itself. We call communism the real movement which abolishes the present state of things. The conditions of this movement result from the premises now in existence." (from The German Ideology)

While Marx was a relatively obscure figure in his own lifetime, his ideas began to exert a major influence on workers' movements shortly after his death. This influence was given added impetus by the victory of the Marxist Bolsheviks in the Russian October Revolution, and there are few parts of the world which were not significantly touched by Marxian ideas in the course of the twentieth century.

Biography

Karl Heinrich Marx was born in Trier, in the Kingdom of Prussia's Province of the Lower Rhine, the third of seven children. His father, Heinrich Marx (1777–1838), born Herschel Mordechai, the son of Levy Mordechai (1743-1804) and Eva Lwow (1753-1823), was descended from a long line of rabbis but converted to Lutheran Christianity, despite his many deistic tendencies and his admiration of such Enlightenment figures as Voltaire and Rousseau, in order to be allowed to practice Law. Marx's mother was Henriette née Pressburg (1788–1863). His siblings were Sophie (d. 1883) (m. Wilhelm Robert Schmalhausen), Hermann (1819-1842), Henriette (1820-1856), Louise (1821-1893) (m. Johann Carel Juta), Emilie, Caroline (1824-1847) and Eduard (1834-1837). His mother was the grand-aunt of industrialists Gerard Philips and Anton Philips and a maternal descendant of the Barent-Cohen family through her parents Isaac Heijmans Presburg (Presburg, c. 1747 – Nijmegen, May 3, 1832) and wife Nanette Salomon Barent-Cohen (Amsterdam, c. 1764 – Nijmegen, April 7, 1833), the daughter of Salomon David Barent-Cohen (d. 1807) and wife Sara Brandes, in turn the uncle and aunt by marriage of Nathan Mayer Rothschild's wife.
