Communism is a political and economic ideology that aims at a classless society in which the means of production are owned in common and goods are distributed according to need, summed up in Marx's phrase "from each according to his ability, to each according to his needs." In the theory set out by Karl Marx and Friedrich Engels, private ownership of capital, social classes and eventually the state itself would disappear.
The word is used in two senses. One is the theoretical end-state described by Marxism. The other is the system run by communist parties that took power in the twentieth century, notably in the Soviet Union and China, which called themselves socialist states building toward communism. Communism is the most radical alternative to capitalism and is related to, but narrower than, socialism.
Communism in plain terms
Imagine a large family farm where nobody owns their own field. Everyone works the land, the harvest goes into a common store, and each household takes what it needs. No one pays rent, no one hires anyone else, and nobody gets rich from someone else's work. That is the communist ideal, applied to a whole society.
In practice, running an entire country this way meant that a single party and a central planning office decided what every factory should make, how much it should cost and where people should work. The ideal was equality and shared ownership; the reality, critics say, was a powerful state that controlled both the economy and people's lives.
Origins in Marxist theory
Marx and Engels published the Communist Manifesto in 1848. Marx's Capital (first volume 1867) argued, building on the labor theory of value, that capitalists profit by paying workers less than the value they create. He predicted that competition and crises would concentrate wealth, impoverish workers and lead to revolution. After a transitional "dictatorship of the proletariat," a socialist stage would pay people according to their work, and full communism would follow once abundance made money and the state unnecessary.
Vladimir Lenin adapted these ideas to Russia, arguing that a disciplined vanguard party should lead the revolution. Later variants include Stalin's model of rapid state-led industrialization, Mao Zedong's peasant-based revolution in China, and Trotskyist and other dissident currents.
How communist economies worked
The Soviet Union, founded in 1922, built the template followed by most communist states:
- Central planning. A state planning agency, Gosplan in the Soviet case, set five-year plans with output targets for each industry. Prices were fixed administratively rather than by supply and demand.
- State and collective ownership. Nationalization put industry, banking and trade in state hands, while farms were collectivized, often by force.
- A monobank. A single state bank handled payments and credit according to the plan, and the currency was not freely convertible, backed up by strict capital controls.
- Guaranteed employment. Open unemployment was officially absent, though hidden underemployment was common.
The model delivered fast heavy industrialization, mass literacy and military power. It also produced chronic shortages of consumer goods, queues, poor quality, weak innovation and a large informal economy. Forced collectivization contributed to devastating famines, including the Soviet famine of 1932–33 and the famine that followed China's Great Leap Forward (1958–62), each estimated to have killed millions of people. Political repression, labor camps and the absence of free elections are central to most historical assessments.
Reform and collapse
From 1978 China under Deng Xiaoping began market reforms: household farming, private businesses, special economic zones and later stock exchanges, while the Communist Party kept political control and the state kept large enterprises. Vietnam followed with its Doi Moi reforms in 1986. In Europe, the fall of the Berlin Wall in 1989 was followed by the end of communist rule across Eastern Europe, and the Soviet Union dissolved in December 1991. The transition brought privatization, high inflation and sharp falls in output in several countries before growth returned.
As of 2026, five states are ruled by communist parties: China, Vietnam, Laos, Cuba and North Korea (which now presents its ideology as Juche rather than Marxism-Leninism). China and Vietnam run large market sectors and are often described as state capitalist or authoritarian capitalist.
Debate and assessments
Critics from free-market and liberal traditions argue that the communist record shows central planning cannot coordinate a modern economy and that concentrating economic and political power leads to repression; economists of the Austrian school predicted the information problems in advance. Defenders and sympathetic historians point to rapid industrialization, gains in health and education, and the role of communist movements in pushing capitalist countries toward welfare states and labor rights. Many Marxists argue that the Soviet model was a distortion of Marx's ideas rather than their fulfillment. Communism remains a reference point in debates about inequality and the limits of markets.
