The Generalplan Ost, abbreviated GPO, was the Nazi German government's plan for the genocide and ethnic cleansing on a vast scale, and colonization of Central and Eastern Europe by Germans. It was to be undertaken in territories occupied by Germany during World War II. The plan was attempted during the war, resulting indirectly and directly in the deaths of millions by shootings, starvation, disease, extermination through labor, and genocide. But its full implementation was not considered practicable during the major military operations, and was prevented by Germany's defeat.

The August Frank memorandum of 26 September 1942 was a directive from SS Lieutenant General (Obergruppenführer) August Frank of the SS concentration camp administration department (SS-WVHA). The memorandum provides a measure of the detailed planning that Frank and other Nazis put into the carrying out of the Holocaust. It includes instructions as to the disposition of postage stamp collections and underwear of the murdered Jews. It is clear that the Nazis were intent in removing everything of value from their victims.

"Green Folder" refers to a document belonging to Reichsmarschall Hermann Göring which was presented in the Nuremberg Trials. This was the master policy directive for the economic exploitation of the conquered Soviet Union. The implications of this document were the deaths by starvation of millions of Slavic people, something that partially came to pass in the Holocaust, the neglect of Soviet soldiers captured by the Nazis which led to huge mortality rates, and the general expropriation of food in the occupied areas of the Soviet Union. It is also referred to as Document of the Soviet Prosecution, Exhibit USSR 10.

Reinhard Tristan Eugen Heydrich was a high-ranking German SS and police official during the Nazi era and a principal architect of the Holocaust. He was chief of the Reich Security Main Office. He was also Stellvertretender Reichsprotektor of Bohemia and Moravia. He served as president of the International Criminal Police Commission and chaired the January 1942 Wannsee Conference which formalised plans for the "Final Solution to the Jewish Question"—the deportation and genocide of all Jews in German-occupied Europe.

Martin Franz Julius Luther was an early member of the Nazi Party. He served as an advisor to Foreign Minister Joachim von Ribbentrop, first in the Dienststelle Ribbentrop, and later in the Auswärtiges Amt as a diplomat when von Ribbentrop replaced Konstantin von Neurath. He participated in the Wannsee Conference, at which the Final Solution was planned; it was the 1947 discovery of his copy of the minutes that first made the Allied powers aware that the conference had taken place and what its purpose was.
The Nisko Plan was an operation to deport Jews to the Lublin District of the General Governorate of occupied Poland in 1939. Organized by Nazi Germany, the plan was cancelled in early 1940.

The Posen speeches were two speeches made by Heinrich Himmler, the head of the SS of Nazi Germany, on 4 and 6 October 1943 in the town hall of Posen (Poznań), in German-occupied Poland. The recordings are the first known documents in which a member of the Hitler Cabinet spoke of the ongoing extermination of the Jews in extermination camps. They demonstrate that the German government wanted, planned and carried out the Holocaust.

The Reich Chancellery meeting of 12 December 1941 was an encounter between Adolf Hitler and the highest-ranking officials of the Nazi Party. Almost all important party leaders were present to hear Hitler declare the ongoing destruction of the Jewish race, culminating in the Holocaust, yet it remains less known than the later Wannsee Conference.

Sonderaktion 1005, also called Aktion 1005, or Enterdungsaktion, began in May 1942 during World War II to hide any evidence that people had been murdered by Nazi Germany in German-occupied Poland and Soviet Union. The project, which was conducted in secrecy from 1942 to 1944, focused on concealing evidence of mass murder at the Operation Reinhard killing centres, as well as at other sites. Groups of Sonderkommando prisoners, officially called Leichenkommandos, were used to exhume mass graves and burn the bodies; inmates were often put in chains to prevent them from escaping.

The SS Main Economic and Administrative Office, abbreviated SS-WVHA, was a Nazi organization responsible for managing the finances, supply systems and business projects for the Allgemeine-SS. It also ran the concentration camps and was instrumental in the implementation of the Final Solution through such subsidiary offices as the Concentration Camps Inspectorate and SS camp guards.

The Wannsee Conference was a meeting of senior government officials of Nazi Germany and Schutzstaffel (SS) leaders, held in the Berlin suburb of Wannsee on 20 January 1942. The purpose of the conference, called by the director of the Reich Security Main Office SS-Obergruppenführer Reinhard Heydrich, was to ensure the co-operation of administrative leaders of various government departments in the implementation of the Final solution to the Jewish question, whereby most of the Jews of German-occupied Europe would be deported to occupied Poland and murdered. Conference participants included representatives from several government ministries, including state secretaries from the Foreign Office, the justice, interior, and state ministries, and representatives from the SS. In the course of the meeting, Heydrich outlined how European Jews would be rounded up and sent to extermination camps in the General Government, where they would be killed.

Wannsee House and the Holocaust by Steven Lehrer tells the story of the elegant suburban Berlin villa where the Wannsee Conference took place on January 20, 1942. At that meeting, Reinhard Heydrich announced the plans for the deportation and extermination of all Jews in German-occupied territory. This to be coordinated with the representatives from the Nazi state agencies present at the meeting.
