Summary execution in the context of "Malmedy massacre"

The Nuremberg trials were international criminal trials held by France, the Soviet Union, the United Kingdom, and the United States against leaders of the defeated Nazi Germany for plotting and carrying out invasions of several countries across Europe and committing atrocities against their citizens in the Second World War.

Between 1939 and 1945, Nazi Germany invaded many countries across Europe, inflicting 27 million deaths in the Soviet Union alone. Proposals for how to punish the defeated Nazi leaders ranged from a show trial (the Soviet Union) to summary executions (the United Kingdom). In mid-1945, France, the Soviet Union, the United Kingdom, and the United States agreed to convene a joint tribunal in Nuremberg, occupied Germany, with the Nuremberg Charter as its legal instrument. Between 20 November 1945 and 1 October 1946, the International Military Tribunal (IMT) tried 22 of the most important surviving leaders of Nazi Germany in the political, military, and economic spheres, as well as six German organizations. The purpose of the trial was not only to try the defendants but also to assemble irrefutable evidence of Nazi war crimes, offer a history lesson to the defeated Germans, and delegitimize the traditional German elite.

Political repression is the act of a state entity controlling a citizenry by force for political reasons, particularly for the purpose of restricting or preventing the citizenry's ability to take part in the political life of a society, thereby reducing their standing among their fellow citizens. Repression tactics target the citizenry who are most likely to challenge the political ideology of the state in order for the government to remain in control. In autocracies, the use of political repression is to prevent anti-regime support and mobilization. It is often manifested through policies such as human rights violations, surveillance abuse, police brutality, kangaroo courts, imprisonment, involuntary settlement, stripping of citizen's rights, lustration, and violent action or terror such as murder, summary executions, torture, forced disappearance, and other extrajudicial punishment of political activists, dissidents, or the general population. Direct repression tactics are those targeting specific actors who become aware of the harm done to them while covert tactics rely on the threat of citizenry being caught (wiretapping and monitoring). The effectiveness of the tactics differs: covert repression tactics cause dissidents to use less detectable opposition tactics while direct repression allows the citizenry to witness and react to the repression. Political repression can also be reinforced by means outside of written policy, such as by public and private media ownership and by self-censorship within the public.

Where political repression is sanctioned and organised by the state, it may constitute state terrorism, genocide, politicide or crimes against humanity. Systemic and violent political repression is a typical feature of dictatorships, totalitarian states and similar regimes. While the use of political repression varies depending on the authoritarian regime, it is argued that repression is a defining feature and the foundation of autocracies by creating a power hierarchy between the leader and citizenry, contributing to the longevity of the regime. Repressive activities have also been found within democratic contexts as well. This can even include setting up situations where the death of the target of repression is the result. If political repression is not carried out with the approval of the state, a section of government may still be responsible. Some examples are the COINTELPRO operations by the FBI from 1956 to 1971 and the Palmer Raids from 1919 to 1920.

The Guatemalan genocide, also referred to as the Maya genocide, or the Silent Holocaust (Spanish: Genocidio guatemalteco, Genocidio maya, or Holocausto silencioso), was the mass killing of the Maya Indigenous people during the Guatemalan Civil War (1960–1996) by successive Guatemalan military governments that first took power following the CIA-instigated 1954 Guatemalan coup d'état. Massacres, forced disappearances, torture and summary executions of guerrillas and especially civilians at the hands of security forces had been widespread since 1965, and was a longstanding policy of the U.S. backed military regimes. Human Rights Watch (HRW) has documented "extraordinarily cruel" actions by the armed forces, mostly against civilians.

The repression reached genocidal levels in the predominantly indigenous northern provinces where the Guerrilla Army of the Poor operated. There, the Guatemalan military viewed the Maya as siding with the insurgency and began a campaign of mass killings and disappearances of Mayan peasants. While massacres of indigenous peasants had occurred earlier in the war, the systematic use of terror against them began around 1975 and peaked during the first half of the 1980s. The military carried out 626 massacres against the Maya during the conflict and acknowledged destroying 440 Mayan villages between 1981 and 1983. In some municipalities, at least one-third of the villages were evacuated or destroyed. A March 1985 study by the Juvenile Division of the Supreme Court estimated that over 200,000 children had lost at least one parent in the war, and that between 45,000 and 60,000 adult Guatemalans were killed between 1980 and 1985. Children were often targets of mass killings by the army, including in the Río Negro massacres between 1980 and 1982. A 1984 report by HRW discussed "the murder of thousands by a military government that maintains its authority by terror". In fact, the rights abuses were so severe that even the U.S. with its fervent anticommunist policy "kept its assistance comparatively limited. For most of the 1980's the Guatemalan army relied on fellow pariah-states like Argentina and South Africa for supplies."

The Soviet invasion of Poland was a military conflict by the Soviet Union without a formal declaration of war. On 17 September 1939, the Soviet Union invaded Poland from the east, 16 days after Nazi Germany invaded Poland from the west. Subsequent military operations lasted for the following 20 days and ended on 6 October 1939 with the two-way division and annexation of the entire territory of the Second Polish Republic by Nazi Germany and the Soviet Union. This division is sometimes called the Fourth Partition of Poland. The Soviet (as well as German) invasion of Poland was indirectly indicated in the "secret protocol" of the Molotov–Ribbentrop Pact signed on 23 August 1939, which divided Poland into "spheres of influence" of the two powers. German and Soviet cooperation in the invasion of Poland has been described as co-belligerence.

The Red Army, which vastly outnumbered the Polish defenders, achieved its targets, encountering only limited resistance. Some 320,000 Poles were made prisoners of war. The campaign of mass persecution in the newly acquired areas began immediately. In November 1939 the Soviet government annexed the entire Polish territory under its control. Some 13.5 million Polish citizens who fell under the military occupation were made Soviet subjects following show elections conducted by the NKVD secret police in an atmosphere of terror, the results of which were used to legitimise the use of force. A Soviet campaign of political murders and other forms of repression, targeting Polish figures of authority such as military officers, police, and priests, began with a wave of arrests and summary executions. The Soviet NKVD sent hundreds of thousands of people from eastern Poland to Siberia and other remote parts of the Soviet Union in four major waves of deportation between 1939 and 1941.Soviet forces occupied eastern Poland until the summer of 1941 when Germany terminated its earlier pact with the Soviet Union and invaded the Soviet Union under the code name Operation Barbarossa. The area was under German occupation until the Red Army reconquered it in the summer of 1944. An agreement at the Yalta Conference permitted the Soviet Union to annex territories close to the Curzon Line (which almost coincided with all of their Molotov–Ribbentrop Pact portion of the Second Polish Republic), compensating the Polish People's Republic with the greater southern part of East Prussia and territories east of the Oder–Neisse line. The Soviet Union appended the annexed territories to the Ukrainian, Byelorussian and Lithuanian Soviet Socialist Republics.

The Nepalese Civil War (1996–2006) was a protracted and countrywide armed conflict in the then Kingdom of Nepal between the Kingdom's rulers and the Communist Party of Nepal (Maoist), with the latter making significant use of guerrilla warfare. It began on 13 February 1996, when the CPN(M) initiated an insurgency with the stated purpose of overthrowing the Nepali monarchy and establishing a people's republic. It ended with the signing of the Comprehensive Peace Accord on 21 November 2006.

The conflict was characterized by numerous war crimes and crimes against humanity, including summary executions, massacres, purges, kidnappings, and mass rapes. It resulted in the deaths of over 17,000 people, including civilians, insurgents, and army and police personnel; and the internal displacement of hundreds of thousands of people, mostly throughout rural Nepal. The Truth and Reconciliation Commission has received about 63,000 complaints, as reported by commissioner Madhabi Bhatta, while the Commission for Investigation of Enforced Disappearances has received around 3,000.

An extrajudicial killing (also known as an extrajudicial execution or an extralegal killing) is the deliberate killing of a person without the lawful authority granted by a judicial proceeding. It typically refers to government authorities, whether lawfully or unlawfully, targeting specific people for death, which in authoritarian regimes often involves political, trade union, dissident, religious and social figures. The term is typically used in situations that imply the human rights of the victims have been violated. Deaths caused by legal police actions (such as self defense) or legal warfighting on a battlefield are generally not included, even though military and police forces are often used for killings seen by critics as illegitimate. The label "extrajudicial killing" has also been applied to organized, lethal enforcement of extralegal social norms by non-government actors, including lynchings and honor killings.
