Despite their totalitarian tendencies, the communist societies of the Soviet Union and China were laced with conflict. Under both Stalin and Mao, those conflicts erupted in a search for enemies that disfigured both societies. An elastic concept of “enemy” came to include not only surviving remnants from the prerevolutionary elites but also, and more surprisingly, high-ranking members and longtime supporters of the Communist Party who allegedly had been corrupted by bourgeois ideas. Refracted through the lens of Marxist thinking, these people became class enemies who had betrayed the revolution and were engaged in a vast conspiracy, often linked to foreign imperialists, to subvert the socialist enterprise and restore capitalism. In the rhetoric of the leadership, the class struggle continued and even intensified as the triumph of socialism drew closer.

In the Soviet Union, that process culminated in the Terror, or the Great Purges, of the late 1930s, which enveloped tens of thousands of prominent communists, including virtually all of Lenin’s top associates, and millions of more ordinary people. (See Document 21.4 and the Portrait of Anna Dubova for individual experiences of the Terror.) Based on suspicious associations in the past, denunciations by colleagues, connections to foreign countries, or simply bad luck, such people were arrested, usually in the dead of night, and then tried and sentenced either to death or to long years in harsh and remote labor camps known as the gulag. A series of show trials publicized the menace that these “enemies of the people” allegedly posed to the country and its revolution. Close to 1 million people were executed between 1936 and 1941. Perhaps an additional 4 or 5 million were sent to the gulag, where they were forced to work in horrendous conditions and died in appalling numbers. Victimizers too were numerous: the Terror consumed the energies of a huge corps of officials, investigators, interrogators, informers, guards, and executioners, many of whom themselves were arrested, exiled, or executed in the course of the purges.

In the Soviet Union, the search for enemies occurred under the clear control of the state. In China, however, it became a much more public process, escaping the control of the leadership, particularly during the Cultural Revolution of 1966–1969. Mao had become convinced that many within the Communist Party had been seduced by capitalist values of self-seeking and materialism and were no longer animated by the idealistic revolutionary vision of earlier times. Therefore, he called for rebellion, against the Communist Party itself. Millions of young people responded, and, organized as Red Guards, they set out to rid China of those who were “taking the capitalist road.” Following gigantic and ecstatic rallies in Beijing, they fanned out across the country and attacked local party and government officials, teachers, intellectuals, factory managers, and others they defined as enemies. (See Visual Sources 21.1 and 21.4.) Rival revolutionary groups soon began fighting with one another, violence erupted throughout the country, and civil war threatened China. Mao was forced to call in the military to restore order and Communist Party control. Both the Soviet Terror and the Chinese Cultural Revolution badly discredited the very idea of socialism and contributed to the ultimate collapse of the communist experiment at the end of the century.
