Communism is a political and economic ideology that positions itself in opposition to liberal democracy and capitalism, advocating instead for a classless system in which the means of production are owned communally and private property is nonexistent or severely curtailed. 

Understanding Communism

"Communism" is an umbrella term that encompasses a range of ideologies. The term's modern usage originated with Victor d'Hupay, an 18th-century French aristocrat who advocated living in "communes" in which all property would be shared, and "all may benefit from everybody's work."

The idea was hardly new, even at that time, however: The Bible's Book of Acts describes 1st-Century Christian communities holding property in common, according to a system known as koinonia, which inspired later religious groups such as the 17th-century English "Diggers" to reject private ownership.

The Communist Manifesto

Modern communist ideology began to develop during the French Revolution, and its seminal tract, Karl Marx and Friedrich Engels' "Communist Manifesto," was published in 1848. That pamphlet rejected the Christian tenor of previous communist philosophies, laying out a materialist and—its proponents claim—scientific analysis of the history and future trajectory of human society. "The history of all hitherto existing society," Marx and Engels wrote, "is the history of class struggles."

The Communist Manifesto presented the French Revolution as a major historical turning point when the "bourgeoisie"—the merchant class that was in the process of consolidating control over the "means of production"—overturned the feudal power structure and ushered in the modern, capitalist era. That revolution replaced the medieval class struggle, which pitted the nobility against the serfs, with the modern one pitting the bourgeois owners of capital against the "proletariat," the working class who sell their labor for wages.

In the Communist Manifesto and later works, Marx, Engels, and their followers advocated for (and predicted as historically inevitable) a global proletarian revolution, which would usher in first an era of socialism, then of communism.

The Communist economy would function, as a popular Marxist slogan puts it, "from each according to his ability, to each according to his needs."

The Soviet Union

Marx and Engels' theories wouldn't be tested in the real world until after their deaths. In 1917, during World War I, an uprising in Russia toppled the czar and sparked a civil war that eventually saw a group of radical Marxists led by Vladimir Lenin gain power in 1922. The Bolsheviks, as this group was called, founded the Soviet Union on former Imperial Russian territory and attempted to put communist theory into practice.

Prior to the Bolshevik Revolution, Lenin had developed the Marxist theory of vanguardism, which argued that a close-knit group of politically enlightened elites was necessary to usher in the higher stages of economic and political evolution: socialism and finally communism.

Lenin died shortly after the civil war ended, but the "dictatorship of the proletariat," led by his successor Joseph Stalin, would pursue brutal ethnic and ideological purges as well as forced agricultural collectivization. Tens of millions died during Stalin's rule, from 1922 to 1953, on top of the tens of millions who died as a result of the war with Nazi Germany.

This system of central planning enabled rapid industrialization, and from 1950 to 1965, growth in Soviet gross domestic product (GDP) outpaced that of the U.S. In general, however, the Soviet economy grew at a much slower pace than its capitalist, democratic counterparts.

Weak consumer spending was a particular drag on growth. Central planners' emphasis on heavy industry led to chronic underproduction of consumer goods, and long lines at understocked grocery stores were a fixture of Soviet life even during periods of relative prosperity.

The Soviet Union collapsed in 1991 after a push to reform the economic and political system and provide greater room for private enterprise and free expression. These reform pushes, known as perestroika and glasnost, respectively, didn't halt the economic decline the Soviet Union suffered in the 1980s and likely hastened the Communist state's end by loosening its grip on sources of dissent.

Communist China

In 1949, after more than 20 years of war with the Chinese Nationalist Party and Imperial Japan, Mao Zedong's Communist Party gained control of China to form the world's second major Marxist-Leninist state. Mao allied the country with the Soviet Union, but the Soviets' policies of de-Stalinization and "peaceful coexistence" with the capitalist West led to a diplomatic split with China around 1958.

Mao's rule in China resembled Stalin's in its violence, deprivation, and insistence on ideological purity. During the Great Leap Forward from 1958 to 1962, the Communist Party ordered the rural population to produce enormous quantities of steel in an effort to jumpstart an industrial revolution in China.

The same period's Great Chinese Famine killed at least 16 million people and perhaps more than 45 million. The Cultural Revolution, an ideological purge that lasted from 1966 until Mao's death in 1976, killed perhaps a further 1.6 million people and subjected millions of others to political persecution.

After Mao's death, Deng Xiaoping introduced a series of market reforms that remained in effect under his successors. The U.S. began normalizing relations with China when President Nixon visited in 1972, prior to Mao's death.

The Chinese Communist Party (CCP) remains in power, presiding over a largely capitalist system, though state-owned enterprises continue to form a large part of the economy. Freedom of expression is significantly curtailed and meaningful opposition to the reining Communist Party isn't permitted. In short, it would take a miracle for the CCP to be ousted.

The Cold War

The U.S. emerged from World War II as the world's richest and most militarily powerful nation. As a liberal democracy that had just defeated fascist dictatorships in two theaters, the country—if not all of its people—felt a sense of exceptionalism and historical purpose. So did the Soviet Union, its ally in the fight against Germany and the world's only revolutionary Marxist state. The two powers promptly divided Europe into spheres of political and economic influence: Winston Churchill called this dividing line the "Iron Curtain."

The two superpowers, both of which possessed nuclear weapons after 1949, engaged in a long standoff known as the Cold War. The closest the U.S. came to a direct military conflict with the Soviet Union was the 1962 Cuban missile crisis. The U.S. did fight a prolonged war in Vietnam, however, in which its military supported South Vietnamese forces fighting the Chinese- and Soviet-supported North Vietnamese army and South Vietnamese communist guerrillas. The U.S. withdrew from the war and Vietnam was united under communist rule in 1975.

The Cold War ended with the collapse of the Soviet Union in 1991.

Why Did Communism Fail?

While there has been extensive study of the reasons for communism's failure, researchers have pinpointed a couple of common factors that contributed to its demise.

The first is an absence of incentives among citizens to produce for profit. The profit incentive leads to competition and innovation in society. But an ideal citizen in a communist society was selflessly devoted to societal causes and rarely stopped to think about their own welfare.

The second reason for communism's failure was the system's inherent inefficiencies, such as centralized planning. This form of planning requires aggregation and synthesis of enormous amounts of data at a granular level. Because all projects were planned centrally, this form of planning was also complex. In several instances, growth data was fudged or error-prone in order to make facts fit into planned statistics and create an illusion of progress. The concentration of power in the hands of a select few also bred inefficiency and, paradoxically enough, provided them with incentives to game the system for their benefit and retain their hold on power. Corruption and laziness became endemic features of this system and surveillance, such as characterized East German and Soviet societies, was common. It also disincentivized industrious and hard-working people. In the end, the economy suffered.

The Bottom Line

Communism, as a theory, has been around since the beginning of humanity. However, it was the French Revolution, Karl Marx, and Friedrich Engels who turned it into an influential political ideology.  Since then, the idea of a classless society in which all property and wealth are communally owned has been tarnished somewhat. While it has existed harmoniously in smaller communities, on a larger level communism has so far failed to be successfully implemented. The two major examples we have are in Russia and China, where communist leaders ruled with violence and suppression and often gamed the system for their own benefit.

Some say this proves communism doesn’t work. Others argue that these regimes deviated from communism and shouldn’t, therefore, be considered as examples.
