Context: The Final Solution (German: "Endlösung" ) or the Final Solution to the Jewish Question (German: "die Endlösung der Judenfrage" , ] ) was a Nazi plan for the extermination of the Jews during World War II.  The “Final Solution of the Jewish Question” was the Nazi code name for the plan to murder all Jews within reach, and was not limited to the European continent.  This policy of deliberate and systematic genocide starting across German-occupied Europe was formulated in procedural and geo-political terms by Nazi leadership in January 1942 at the Wannsee Conference near Berlin, and culminated in the Holocaust which saw the killing of 90 percent of Jewish Poles, and two-thirds of the Jewish population of Europe. 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. Friedrich Minoux (21 March 1877 – 16 October 1945) was a German industrialist and financier who is best known for being one of the owners of the Wannsee House, where the namesake conference that would decide the fate of millions at the hands of the Nazis during World War II was held in early 1942. Reinhard Tristan Eugen Heydrich (] ) (7 March 1904 – 4 June 1942) was a high-ranking German Nazi official during World War II, and a main architect of the Holocaust.  He was an SS-"Obergruppenführer und General der Polizei" (Senior Group Leader and General of Police) as well as chief of the Reich Main Security Office (including the Gestapo, Kripo, and SD).  He was also "Stellvertretender Reichsprotektor" (Deputy/Acting Reich-Protector) of Bohemia and Moravia.  Heydrich served as president of the International Criminal Police Commission (ICPC; later known as Interpol) 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. The Reich Chancellery and Führerbunker Complex: An Illustrated History of the Seat of the Nazi Regime is a 2006 book by Steven Lehrer, in which Lehrer recounts the history of a group of Berlin buildings, from their construction in the 18th century until their complete destruction during and after World War II. The Wannsee Conference (German: "Die Wannseekonferenz" ) is a 1984 German TV film portraying the events of the Wannsee Conference, held in Berlin in January 1942.  The script is derived from the minutes of the meeting.  Since no verbatim transcription of the meeting exists, the dialogue is necessarily fictionalised.  The main theme of the film is the bureaucratic nature of the genocide. Fatherland is a 1992 alternate history detective novel by English writer and journalist Robert Harris.  Set in a universe where Nazi Germany won World War II, the story's lead protagonist is an SS officer investigating the murder of a Nazi government official who was one of the participants at the Wannsee Conference.  In so doing, he discovers a plot to eliminate all attendees of the conference in order to help Germany establish better political relations with the United States. The Wannsee Conference (German: "Wannseekonferenz" ) 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 Main Security Office SS-"Obergruppenführer" Reinhard Heydrich, was to ensure the cooperation of administrative leaders of various government departments in the implementation of the so-called Final solution to the Jewish question, whereby most of the Jews of German-occupied Europe would be deported to Poland and murdered.  Conference attendees 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 (the occupied part of Poland), where they would be killed. The Rumbula massacre is a collective term for incidents on two non-consecutive days (November 30 and December 8, 1941) in which about 25,000 Jews were killed in or on the way to Rumbula forest near Riga, Latvia, during the Holocaust.  Except for the Babi Yar massacre in Ukraine, this was the biggest two-day Holocaust atrocity until the operation of the death camps.  About 24,000 of the victims were Latvian Jews from the Riga Ghetto and approximately 1,000 were German Jews transported to the forest by train.  The Rumbula massacre was carried out by the Nazi Einsatzgruppe A with the help of local collaborators of the Arajs Kommando, with support from other such Latvian auxiliaries.  In charge of the operation was Higher SS and Police Leader Friedrich Jeckeln, who had previously overseen similar massacres in Ukraine.  Rudolf Lange, who later participated in the Wannsee Conference, also took part in organising the massacre.  Some of the accusations against Latvian Herberts Cukurs are related to the clearing of the Riga Ghetto by the Arajs Kommando.  The Rumbula killings, together with many others, formed the basis of the post-World War II Einsatzgruppen trial where a number of Einsatzgruppen commanders were found guilty of crimes against humanity. The Seventy Years Declaration was a declaration initiated by academics Dovid Katz and Danny Ben-Moshe and released on 20 January 2012 to protest against the policies of several European states and European Union bodies on the evaluation, remembrance and prosecution of crimes committed under communist dictatorships in Europe, specifically policies of many European countries and the EU treating the Nazi and Stalinist regimes in Eastern and Central Europe as equally criminal.  Presented as a response to the Prague Declaration on European Conscience and Communism initiated by the Czech government in 2008 to condemn communism as totalitarian and criminal, it explicitly rejects the idea that the regimes of Joseph Stalin and Adolf Hitler can be compared, i.e. the totalitarianism theory that was popularized by academics such as Hannah Arendt, Carl Friedrich and Zbigniew Brzezinski and became dominant in western political discourse during the Cold War, and that has gained new momentum in many new EU member states following the fall of communism, resulting in international resolutions, establishment of research institutes and museums, and a day of remembrance.  The declaration also claims communist regimes did not commit genocides, citing a 1948 definition that deliberately excluded politically motivated mass killings as demanded by the Soviet Union when it was adopted.  More recent definitions do however include such crimes, and e.g. The Holodomor is recognized as a genocide by the United States, Ukraine and other countries.  The declaration advances the position that the Holocaust was "unique" as compared to other genocides, a subject of some debate.  This position first appeared in discourse in 1967, but does not figure in scholarship of the Holocaust, has become less common since the 1994 Rwandan genocide, and was described as a "vacuous" and "deeply offensive" position by Peter Novick.  The declaration was signed by 70, mostly left-wing, parliamentarians from Europe (MEPs and national MPs).  It was released on the 70th anniversary of the Wannsee Conference in Berlin.
