Friedrich Engels (1820–1895) was a German philosopher, political theorist, economist, and social critic, best known for his lifelong collaboration with Karl Marx. He co-authored The Communist Manifesto (1848) and played a major role in developing the ideas that became known as Marxism. Engels also wrote influential works
of his own, including The Condition
of the Working Class in England, based on his observations
of industrial society. After Marx's death, he edited and published the second and third volumes
of Das Kapital from Marx's manuscripts.
