Alexandru Drăghici (] ; September 27, 1913 – December 12, 1993) was a Romanian communist activist and politician.
 He was Interior Minister in 1952 and from 1957 to 1965, and State Security Minister from 1952 to 1957.
 In these capacities, he exercised control over the "Securitate" secret police during a period of active repression against other Communist Party members, anti-communist resistance members and ordinary citizens.
The First Of March Organization (Organizacion Primero de Marzo) (OPM) was a clandestine movement created in Paraguay in the mid 70s to fight General Alfredo Stroessner’s dictatorship.
 It was the most serious attempt at creating an armed resistance to the dictator’s repressive government.
 Even though the organization was discovered before it was capable of attacking in the government in any way, the wave of repression which followed the discovery was enormous.
 During that period of repression, several leaders of the organization were captured, tortured and then executed, but the violence also extended to many regions of the country, affecting several agrarian movements and agrarian workers that had nothing to do with the OPM.
In Spain, the punk rock scene emerged in 1978, when the country had just emerged from forty years of fascist dictatorship under General Franco, a state that “melded state repression with fundamentalist Catholic moralism”.
 Even after Franco died in 1975, the country went through a “volatile political period”, in which the country had to try to relearn democratic values and install a constitution.
 When punk emerged, it “did not appropriate socialism as its goal”; instead, it embraced “nihilism”, and focused on keeping the memories of past abuses alive, and accusing all of Spanish society of collaborating with the fascist regime.
The history of Thailand from 1932 to 1973 was dominated by military dictatorships which were in power for much of the period.
 The main personalities of the period were the dictator Luang Phibunsongkhram (better known as Phibun), who allied the country with Japan during the Second World War, and the civilian politician Pridi Phanomyong, who founded Thammasat University and was briefly prime minister after the war.
In 1855 Alexander II began his reign as Tsar of Russia, and presided over a period of political and social reform, notably the emancipation of serfs in 1861 and the lifting of censorship.
 His successor, Alexander III (1881-1894), pursued a policy of repression and restricted public expenditure, but continued land and labour reforms.
 This was a period of population growth and significant industrialization; nevertheless Russia remained a largely rural country.
The "Dirty War" (Spanish: "Guerra Sucia" ), was the name used by the Argentine Military Government for a period of state terrorism in Argentina from roughly 1974 to 1983 (some sources date the beginning to 1969), during which military and security forces and right-wing death squads in the form of the Argentine Anticommunist Alliance (Triple A) hunted down and killed left-wing guerrillas, political dissidents, and anyone believed to be associated with socialism.
 About 30,000 people disappeared, many of which were impossible to be formally reported due to the nature of the issue: state terrorism.
 The targets were left-wing activists, guerrillas and militants, trade unionists, students, journalists and Marxists and Peronist guerrillas and their support network in the Montoneros believed to be 150,000-250,000-strong and 60,000-strong in the ERP, as well as alleged sympathizers.
 Some 10,000 of the "disappeared" were guerrillas of the Montoneros (MPM) and the Marxist People's Revolutionary Army (ERP) although the lowest estimate is that the Montoneros and ERP had a combined strength of 5,000.
 The "disappeared" included those thought to be a political or ideological threat to the military junta, even vaguely, and they were killed in an attempt by the junta to silence the opposition and break the determination of the guerrillas.
 The worst repression reportedly occurred after the guerillas were largely defeated in 1977, when the church, labor unions, artists, intellectuals and university students and professors were targeted.
 Although the Montoneros reported having carried out some 600 armed attacks in 1977, the guerrilla threat had greatly declined.
 The junta justified this mass terror by exaggerating the guerrilla threat, and even staged attacks to be blamed on guerillas and used frozen dead bodies of guerilla fighters that had been kept in storage for this purpose.
 In late 1979, Amnesty International accused the Videla military government of being responsible for the disappearance of 15,000 to 20,000 Argentine citizens since the 1976 coup.
 That year, a special study by the New York City Bar concluded that around 10,000 Argentines had disappeared since the coup.
 According to "Registro Unificado de Víctimas del Terrorismo de Estado" (Ruvte), 662 were disappeared under the presidency of Isabel Perón and 6,348 were disappeared during the military dictatorship.
Japanese dissidence during the early Shōwa period was dissidence by Japanese citizens of the Empire of Japan (1868–1947) during the Shōwa period, the reign of the Shōwa Emperor, Hirohito (1926–1989).
 The early Shōwa period witnessed the rise of Japanese militarism, and Imperial Japan's full-scale invasion of China in the Second Sino-Japanese War (1937–1945), which escalated into a full-scale invasion of the Asia-Pacific during the Pacific theatre of World War II (1941–1945).
 Throughout the period, there was political repression in Imperial Japan.
The Stalinist repressions in Mongolia (Mongolian: Их Хэлмэгдүүлэлт , Ikh Khelmegdüülelt, ""Great Repression"") refers to a period of heightened political violence and persecution in the Mongolian People's Republic between 1937 and 1939.
 The repressions were part of the Stalinist purges (also known as the Great Purge) unfolding across the Soviet Union around the same period.
 Soviet NKVD advisors, under the nominal direction of Mongolia's "de facto" leader Khorloogiin Choibalsan, persecuted individuals and organizations perceived as threats to the Mongolian revolution and the growing Soviet influence in the country.
 As in the Soviet Union, methods of repression included show trials, torture, and imprisonment in remote forced labor camps.
 Estimates differ, but anywhere between 20,000 to 35,000 "enemies of the revolution" were executed, a figure representing three to five percent of Mongolia's total population at the time.
 Victims included those suspected of espousing lamaism, pan-Mongolist nationalism, and pro-Japanese sentiment with the Buddhist clergy, aristocrats, intelligentsia, political dissidents, and ethnic Buryats and Kazakhs suffering the greatest losses.
Augusto José Ramón Pinochet Ugarte (] or ] ; 25 November 1915 – 10 December 2006) was a Chilean general, politician and the dictator of Chile between 1973 and 1990; he remained the Commander-in-Chief of the Chilean Army until 1998.
 He was also president of the Government Junta of Chile between 1973 and 1981.
 His rule of Chile was a dictatorship.
The Popular Unitary Action Movement or MAPU (Spanish: Movimiento de Acción Popular Unitario ) was a small leftist political party in Chile.
 It was part of the Popular Unity coalition during the government of Salvador Allende.
 MAPU was repressed during the dictatorship of Augusto Pinochet.
 In this period, some of its most radical members formed the Movimiento Juvenil Lautaro, whose leaders were political prisoners during the dictatorship and with the return to democracy.
 Another faction of the former members of the party joined the social democratic Party for Democracy in 1987.
