On this day, 14 March 1883, Friedrich Engels sent a wire to Friedrich Adolph Sorge in New York City saying simply “Marx died today!”. German communist Karl Marx had died in London, aged 64. He had travelled to Britain after being banished from Germany, and arrested and imprisoned in Paris, from which he managed to escape.
The Manchester Courier and Lancashire General Advertiser reported that at his funeral Engels, Marx’s lifelong friend and collaborator, described Marx as the “best hated and worst calumniated man in Europe… [who] had lived, although his work was not finished, to see his views embraced by millions of both hemispheres.”
Marx was clear that the driving force of history is the fight against oppression, writing with Engels: “The history of all hitherto existing society is the history of class struggles.
“Freeman and slave, patrician and plebeian, lord and serf, guild-master and journeyman, in a word, oppressor and oppressed, stood in constant opposition to one another, carried on an uninterrupted, now hidden, now open fight, a fight that each time ended, either in a revolutionary reconstitution of society at large, or in the common ruin of the contending classes.
"The modern bourgeois [capitalist] society that has sprouted from the ruins of feudal society has not done away with class antagonisms. It has but established new classes, new conditions of oppression, new forms of struggle in place of the old ones.
"Our epoch, the epoch of the bourgeoisie, possesses, however, this distinct feature: it has simplified class antagonisms. Society as a whole is more and more splitting up into two great hostile camps, into two great classes directly facing each other — Bourgeoisie [capitalists] and Proletariat [the working class].”
