Democide refers to "the intentional killing of an unarmed or disarmed person by government agents acting in their authoritative capacity and pursuant to government policy or high command." The term was first coined by Holocaust historian and statistics expert, R.J. Rummel in his book Death by Government, but has also been described as a better term than genocide to refer to certain types of mass killings, by renowned Holocaust historian Yehuda Bauer. According to Rummel, this definition covers a wide range of deaths, including forced labor and concentration camp victims, extrajudicial summary killings, and mass deaths due to governmental acts of criminal omission and neglect, such as in deliberate famines like the Holodomor, as well as killings by de facto governments, for example, killings during a civil war. This definition covers any murder of any number of persons by any government.
Genocide is the intentional destruction of a people in whole or in part.
The Nanjing Massacre or the Rape of Nanjing was the mass murder of Chinese civilians in Nanjing, the capital of the Republic of China, immediately after the Battle of Nanking in the Second Sino-Japanese War, by the Imperial Japanese Army. Beginning on December 13, 1937, the massacre lasted six weeks. The perpetrators also committed other war crimes such as mass rape, looting, and arson. The massacre is considered to be one of the worst wartime atrocities.
Mass killing is a concept which has been proposed by genocide scholars who wish to define incidents of non-combat killing which are perpetrated by a government or a state. A mass killing is commonly defined as the killing of group members without the intention to eliminate the whole group, or otherwise the killing of large numbers of people without a clear group membership.
Rudolph Joseph Rummel was an American political scientist and professor at the Indiana University, Yale University, and University of Hawaiʻi at Mānoa. He spent his career studying data on collective violence and war with a view toward helping their resolution or elimination. Contrasting genocide, Rummel coined the term democide for murder by government, such as the genocide of indigenous peoples and colonialism, Nazi Germany, the Stalinist purges, Mao Zedong's Cultural Revolution, and other authoritarian, totalitarian, or undemocratic regimes, coming to the conclusion that democratic regimes result in the least democides.
The Empire of Japan committed war crimes and crimes against humanity in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese and Pacific Wars. These incidents have been described as "the Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most were committed during the first part of the Shōwa era, the name given to the reign of Emperor Hirohito.
Estimates of casualties of the Vietnam War vary widely. Estimates can include both civilian and military deaths in North and South Vietnam, Laos, and Cambodia.
Massacre in Korea is an expressionistic painting completed on 18 January 1951 by Pablo Picasso. Picasso's third anti-war painting after Guernica and The Charnel House, Massacre depicts a scene of a massacre of a group of naked women and children by a firing squad. It has been considered to be a condemnation of American intervention in the Korean War. The painting was exhibited in the Musée Picasso in Paris.
The Bodo League massacre was a massacre and a war crime against communists and alleged communist-sympathizers that occurred in the summer of 1950 during the Korean War. Estimates of the death toll vary. Historians and experts on the Korean War estimate that between 60,000 and 200,000 people were killed.
Mass 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. Some authors have tabulated a total death toll, consisting of all of the excess deaths which cumulatively occurred under the rule of communist states, but these death toll estimates have been criticized. Most frequently, the states and events which are studied and included in death toll estimates are the Holodomor and the Great Purge in the Soviet Union, the Great Chinese Famine and the Cultural Revolution in the People's Republic of China, and the Cambodian genocide in Democratic Kampuchea.
Anti-communist mass killings are the politically motivated mass killings of communists, alleged communists, or their alleged supporters which were committed by anti-communists and political organizations or governments which opposed communism. The communist movement has faced opposition since it was founded and the opposition to it has often been organized and violent. Many anti-communist mass killing campaigns waged during the Cold War were supported and backed by the United States and its Western Bloc allies. Some U.S.-supported mass killings, including the Indonesian mass killings of 1965–66 and the killings by the Guatemalan military during the Guatemalan Civil War, are considered acts of genocide by some scholars.
The Sinchon Massacre was a massacre of civilians between 17 October and 7 December 1950, in or near the town of Sinchon. North Korean sources claim the massacre was committed by the U.S. military and that 30,000–35,383 people were killed in Sinchon. South Korean sources dispute the death toll and accuse South Korean right-wing security police and North Korean communists of the killings. The event took place during the second phase of the Korean War and the retreat of the North Korean government from Hwanghae Province.
The South Korean government, under the regime of Park Chung Hee, took an active role in the Vietnam War. South Korea's decision to join resulted from various underlying causes, including the development of US-South Korea relations, political exigencies, and the promise of economic aid from the United States. From September 1964 to March 1973, South Korea sent some 350,000 troops to South Vietnam. The South Korean Army, Marine Corps, Navy, and Air Force all participated as an ally of the United States. The number of troops from South Korea was much greater than those from Australia and New Zealand, and second only to the U.S. military force for foreign troops located in South Vietnam. The military commander was Lieutenant General Chae Myung-shin of the South Korean army. Participation of Korean forces in the war included both non-combatant and combatant roles.
The Sunchon tunnel massacre was a death march followed by a massacre of American POWs during the UN offensive into North Korea. The death march began in October 1950 when around 180 prisoners of war who had survived the Tiger Death March from Seoul to Pyongyang were loaded onto railcars by the Korean People's Army (KPA) and transported deep into North Korea. The journey is said to have taken four to five days. The climate was very harsh and many of the POWs, who were unprotected and given no food, water, or medical treatment, died during the trip.
Since the 1990s, the Amhara people of Ethiopia have been subject to ethnic violence, including massacres by Tigrayan, Oromo and Gumuz ethnic groups among others, which some have characterized as a genocide. Large-scale killings and grave human rights violations followed the implementation of the ethnic-federalist system in the country. In most of the cases, the mass murders were silent with perpetrators from various ethno-militant groups— from TPLF/TDF, OLF–OLA, and Gumuz armed groups.
