Engels, the son of a wealthy textile manufacturer, met Marx in 1844. They jointly authored works including ''The Holy Family'' (1844), ''The German Ideology'' (written 1846), and ''The Communist Manifesto'' (1848), and worked as political organisers and activists in the Communist League and First International. Engels also supported Marx financially for much of his life, enabling him to continue writing after he moved to London in 1849. After Marx's death in 1883, Engels compiled Volumes II and III of his ''Das Kapital'' (1885 and 1894).
Engels wrote eclectic works of his own, including ''The Condition of the Working Class in England'' (1845), ''Anti-Dühring'' (1878), ''Dialectics of Nature'' (1878–1882), ''The Origin of the Family, Private Property and the State'' (1884), and ''Ludwig Feuerbach and the End of Classical German Philosophy'' (1886). His writings on materialism, idealism, and dialectics supplied Marxism with an ontological and metaphysical foundation. Provided by Wikipedia
