“social system based on collective ownership,” 1843, from French communisme (c.1840) from commun (Old French comun; see common (adj.)) + -isme (see -ism). Originally a theory of society; as name of a political system, 1850, a translation of German Kommunismus (itself from French), in Marx and Engels’ “Manifesto of the Communist Party.” Cf. communist. In some cases in early and mid-20c., a term of abuse implying anti-social criminality without regard to political theory.

Each [i.e. socialism, communism, anarchism] stands for a state of things, or a striving after it, that differs much from that which we know; & for many of us, especially those who are comfortably at home in the world as it is, they have consequently come to be the positive, comparative, & superlative, distinguished not in kind but in degree only, of the terms of abuse applicable to those who would disturb our peace.

An economic and social system envisioned by the nineteenth-century German scholar Karl Marx. In theory, under communism, all means of production are owned in common, rather than by individuals (see Marxism and Marxism-Leninism). In practice, a single authoritarian party controls both the political and economic systems. In the twentieth century, communism was associated with the economic and political systems of China and the Soviet Union and of the satellites of the Soviet Union. (Compare capitalism and socialism.)
