Operation Reinhard

1942–1943

The code name for the German operation to murder the Jews of the General Government and the Białystok District in 1942–1943. Odilo Globocnik directed it under Heinrich Himmler; Christian Wirth supervised the killing centres, and Franz Stangl commanded Sobibór and later Treblinka. Estimates place the number murdered at Bełżec, Sobibór and Treblinka at approximately 1.7–1.8 million people, overwhelmingly Polish Jews.

Operation “T4”

1939–1941

The code name for the mass murder of disabled people and psychiatric patients in the German Reich. Adolf Hitler authorised the programme, which Philipp Bouhler and Karl Brandt organised. About 70,000 people were killed by gas or lethal injection in the centralised phase; Nazi propaganda disguised the murders as “euthanasia”. Personnel and methods from “T4” were later transferred to Operation Reinhard.

Denazification

from 1945

The Allied process, begun in 1945, of removing Nazism from public life in Germany and Austria. It included dissolving the NSDAP and its affiliated organisations, screening officials, judges and teachers, and prosecuting perpetrators. Its reach remained incomplete: many perpetrators escaped punishment, returned to professional careers or fled justice.

Einsatzgruppen

1939–1945

Mobile task forces of the Security Police and SD, subordinate to the RSHA. They carried out mass shootings behind the front in occupied Poland from 1939 and throughout the occupied Soviet territories after June 1941. Their victims included more than one million Jews as well as Roma, members of the Polish intelligentsia, psychiatric patients and Soviet prisoners of war.

Gauleiter

1925–1945

General Government

1939–1945

A German occupation administration created in October 1939 in central and south-eastern Polish territories not formally annexed to the Reich.

Ghetto

1939–1944

A compulsory, segregated district in which German occupation authorities confined Jews under conditions of extreme overcrowding, starvation and terror. Ghettos were part of the Holocaust: residents were murdered locally or deported to killing centres. Their administration also joined forced labour and systematic plunder to the process of destruction.

Nazi Germany (the “Third Reich”)

1933–1945

The German state under the dictatorship of Adolf Hitler and the NSDAP from 1933 to 1945. It was a racist and antisemitic dictatorship that launched the Second World War and committed genocide, crimes against humanity and war crimes. “Third Reich” was a political self-description of the regime and is used here only as a historical term.

Reichsgau Wartheland

1939–1945

An administrative district formed in 1939 from western Polish territories illegally annexed to the Reich and ruled by Gauleiter Arthur Greiser.

Genocide

legal term coined in 1944

A crime committed with intent to destroy, in whole or in part, a national, ethnic, racial or religious group. Polish-Jewish jurist Raphael Lemkin coined the term in 1944, and the United Nations codified it in the 1948 Genocide Convention. The Holocaust and the genocide of Roma and Sinti are central examples of Nazi genocide.

IMT — International Military Tribunal

1945–1946

The tribunal of the four Allied powers that tried major German war criminals at Nuremberg in 1945–1946 for crimes against peace, war crimes and crimes against humanity. It imposed twelve death sentences, one in absentia, and declared the leadership corps of the NSDAP, the SS, SD and Gestapo criminal organisations under defined conditions. Its judgment became a foundation of modern international criminal law.

Supreme National Tribunal of Poland

1946–1948

A Polish court operating from 1946 to 1948 to try German perpetrators extradited to Poland. It sentenced Rudolf Höss, Arthur Greiser, Albert Forster and Amon Göth, among others, to death. Its judgments were among the early judicial applications of the concept of genocide.

They examined distinct sectors of the apparatus of crime, including doctors, jurists, ministries, industrialists, military commanders, the Einsatzgruppen and the SS economic administration. The proceedings documented the participation of professional and bureaucratic elites in Nazi crimes.

November Pogroms of 1938 (“Kristallnacht”)

9–10 November 1938

A state-organised pogrom against Jews in Germany and Austria on 9–10 November 1938. More than a thousand synagogues were burned or damaged, thousands of businesses and homes were attacked, at least 91 people were killed and about 30,000 Jewish men were imprisoned in concentration camps. The familiar term “Kristallnacht”, referring to broken shop-window glass, is a perpetrator-era euphemism that obscures the violence.

Related people: Joseph Goebbels

NSDAP

1920–1945

The National Socialist German Workers’ Party, led by Adolf Hitler. From 1933 it was the only legal political party in Germany, and its racist and antisemitic ideology became state policy.

Concentration camp and killing centre

1933–1945

Concentration camps imprisoned, terrorised and exploited people through forced labour; hundreds of thousands died through murder, starvation, disease and exhaustion. Kulmhof, Bełżec, Sobibór and Treblinka were created specifically for immediate mass murder, chiefly of Jews. Auschwitz-Birkenau and Majdanek combined concentration-camp functions with mass killing. These categories describe institutional purpose and should not be collapsed into one another.

“Final Solution to the Jewish Question”

1941–1945

The Nazi regime’s bureaucratic euphemism for the plan to murder Europe’s Jews. Reinhard Heydrich coordinated its state-wide implementation at the Wannsee Conference in January 1942, while Adolf Eichmann’s RSHA section organised deportation logistics. Mass shootings, ghettos and killing centres were interconnected means of carrying out the genocide.

It controlled the Einsatzgruppen and included Eichmann’s deportation office.

SA

1921–1945

The Sturmabteilung was the NSDAP’s paramilitary organisation. Its street violence helped the Nazis gain power, and after 1933 its members participated in anti-Jewish boycotts, early improvised camps and the November 1938 pogroms. After Hitler had much of its leadership murdered in 1934, the SA lost power to the SS.

“Anti-bandit warfare” as cover for repression of civilians

1940–1945

The perpetrator term Bandenbekämpfung joined actual operations against armed groups with collective reprisals against civilians, village pacifications, plunder and deportation.
