In 1845 he published The Condition of the Working Class in England, based on personal observations and research. In 1848 he produced with Marx The Communist Manifesto and later he supported Marx financially to do research and write Das Kapital. After Marx's death Engels edited the second and third volumes. Additionally, Engels organized Marx's notes on the "Theories of Surplus Value" and this was later published as the "fourth volume" of Capital.
