Cambodian genocideThe Cambodian genocide (របបប្រល័យពូជសាសន៍នៅកម្ពុជា) was the systematic persecution and killing of Cambodian citizens by the Khmer Rouge under the leadership of Communist Party of Kampuchea general secretary Pol Pot. It resulted in the deaths of 1.5 to 2 million people from 1975 to 1979, nearly a quarter of Cambodia's population in 1975 ( 7.8 million). Pol Pot and the Khmer Rouge had long been supported by the Chinese Communist Party (CCP) and its chairman, Mao Zedong; it is estimated that at least 90% of the foreign aid which the Khmer Rouge received came from China, including at least US$1 billion in interest-free economic and military aid in 1975 alone.
Mass killings under communist regimesMass killings under communist regimes occurred through a variety of means during the 20th century, including executions, famine, deaths through forced labour, deportation, starvation, and imprisonment. Some of these events have been classified as genocides or crimes against humanity. Other terms have been used to describe these events, including classicide, democide, red holocaust, and politicide. The mass killings have been studied by authors and academics and several of them have postulated the potential causes of these killings along with the factors which were associated with them.
Soviet famine of 1930–1933The Soviet famine of 1930–1933 was a famine in the major grain-producing areas of the Soviet Union, including Ukraine and different parts of Russia, including Northern Caucasus, Kuban Region, Volga Region, Kazakhstan, the South Urals, and West Siberia. Estimates conclude that 5.7 to 8.7 million people died of famine across the Soviet Union. Major contributing factors to the famine include: the forced collectivization of agriculture as a part of the First Five-Year Plan, and forced grain procurement, combined with rapid industrialization and a decreasing agricultural workforce.
Katyn massacreThe Katyn massacre was a series of mass executions of nearly 22,000 Polish military officers and intelligentsia prisoners of war carried out by the Soviet Union, specifically the NKVD ("People's Commissariat for Internal Affairs", the Soviet secret police) in April and May 1940. Though the killings also occurred in the Kalinin and Kharkiv prisons and elsewhere, the massacre is named after the Katyn forest, where some of the mass graves were first discovered by German Nazi forces.
The Black Book of CommunismThe Black Book of Communism: Crimes, Terror, Repression is a 1997 book by Stéphane Courtois, Andrzej Paczkowski, Nicolas Werth, Jean-Louis Margolin, and several other European academics documenting a history of political repression by communist states, including genocides, extrajudicial executions, deportations, and deaths in labor camps and artificially created famines. The book was originally published in France as Le Livre noir du communisme: Crimes, terreur, répression by Éditions Robert Laffont.
Population transferPopulation transfer or resettlement is a type of mass migration, often imposed by state policy or international authority and most frequently on the basis of ethnicity or religion but also due to economic development. Banishment or exile is a similar process, but is forcibly applied to individuals and groups. Population transfer differs more than simply technically from individually motivated migration, but at times of war, the act of fleeing from danger or famine often blurs the differences.
HolodomorThe Holodomor, also known as the Great Ukrainian Famine, was a man-made famine in Soviet Ukraine from 1932 to 1933 that killed millions of Ukrainians. The Holodomor was part of the wider Soviet famine of 1930–1933 which affected the major grain-producing areas of the Soviet Union. While scholars are in consensus that the cause of the famine was man-made, whether the Holodomor constitutes a genocide remains in dispute. Some historians conclude that the famine was planned and exacerbated by Joseph Stalin in order to eliminate a Ukrainian independence movement.
Red TerrorThe Red Terror (krasnyj terror) in Soviet Russia was a campaign of political repression and executions which was carried out by the Bolsheviks, chiefly through the Cheka, the Bolshevik secret police. It officially started in early September 1918 and lasted until 1922. Arising after assassination attempts on Vladimir Lenin and Petrograd Cheka leader Moisei Uritsky in retaliation for Bolshevik atrocities, the latter of which was successful, the Red Terror was modeled on the Reign of Terror of the French Revolution, and sought to eliminate political dissent, opposition, and any other threat to Bolshevik power.
Great Leap ForwardThe Great Leap Forward of the People's Republic of China (PRC) was an economic and social campaign led by the Chinese Communist Party (CCP) from 1958 to 1962. CCP Chairman Mao Zedong launched the campaign to reconstruct the country from an agrarian economy into an industrialized society through the formation of people's communes. Mao decreed that efforts to multiply grain yields and bring industry to the countryside should be increased.
Anti-communismAnti-communism is political and ideological opposition to communist beliefs, groups, and individuals. Organized anti-communism developed after the 1917 October Revolution in the Russian Empire, and it reached global dimensions during the Cold War, when the United States and the Soviet Union engaged in an intense rivalry. Anti-communism has been an element of many movements and different political positions across the political spectrum, including anarchism, centrism, conservatism, fascism, liberalism, nationalism, social democracy, socialism, leftism, and libertarianism, as well as broad movements resisting communist governance.
