Before the start of World War II, around 9.5 million Jewish people lived in Europe. By the time the war ended, the Nazis had killed 6 million European Jews in concentration camps, or pogroms, or ghettos, or mass executions in what we refer to today as the Holocaust. The Nazis used the term Endlösung, or Final Solution, as the “answer” to the “Jewish question.” But when did this monstrous plan get put in motion?
^ "War nicht der 'Archipel Gulag' ursprünglicher als 'Auschwitz'? War nicht der 'Klassenmord' der Bolschewiki das logische und faktische Prius des 'Rassenmords' der Nationalsozialisten? Sind Hitlers geheimste Handlungen nicht gerade auch dadurch zu erklären, daß er den 'Rattenkäfig' nicht vergessen hatte? Rührte Auschwitz vielleicht in seinen Ursprüngen aus einer Vergangenheit her, die nicht vergehen wollte?"[477]
On 15 September 1935, the Reichstag passed the Reich Citizenship Law and the Law for the Protection of German Blood and German Honor, known as the Nuremberg Laws. The former said that only those of "German or kindred blood" could be citizens. Anyone with three or more Jewish grandparents was classified as a Jew.[107] The second law said: "Marriages between Jews and subjects of the state of German or related blood are forbidden." Sexual relationships between them were also criminalized; Jews were not allowed to employ German women under the age of 45 in their homes.[108] The laws referred to Jews but applied equally to the Roma and black Germans.[107]
Belzec, Sobibor, and Treblinka formed part of what the Nazis called “Operation Reinhard,” whose sole purpose was the systematic massacre of Jews. A labor camp existing in Belzec since 1940 was turned into an extermination camp in the autumn of 1941, becoming operative in March 1942. In the same month, the camp at Sobibor was set up to alleviate the overburdened camp of Belzec. The third, Treblinka, received the Jews from Warsaw and the Radom district.
While concentration camps were meant to work and starve prisoners to death, extermination camps (also known as death camps) were built for the sole purpose of killing large groups of people quickly and efficiently. The Nazis built six extermination camps, all in Poland: Chelmno, Belzec, Sobibor, Treblinka, Auschwitz, and Majdanek. (Auschwitz and Majdanek were both concentration and extermination camps.)
The ghettos, and the slow death they brought, were only part of the overall plan. In the months following the Wannsee Conference, three specialized killing centers, Belzec, Treblinka and Sobibor, were constructed in southeast Poland, featuring large gas chambers with adjacent crematories or burial pits for the disposal of corpses. After they became operational, the ghettos were bypassed and Jews went directly by train to the new death camps.

As the war continued, the rescuers learned to adapt and work around the Nazi network of informers and collaborators. However, they were never able to develop effective strategies to combat the Nazis’ rapid organization of mass deportations and population transfers. As the war progressed, rescuers were able to identify sympathetic local groups, individuals, and organizations in every country of occupied Europe; for example, low-level clergymen, Socialists, Communists, and nationalist anti-Nazis. At all times, however, the success of Jewish rescue depended upon fate and chance.
In France Jews under Fascist Italian occupation in the southeast fared better than the Jews of Vichy France, where collaborationist French authorities and police provided essential support to the understaffed German forces. The Jews in those parts of France under direct German occupation fared the worst. Although allied with Germany, the Italians did not participate in the Holocaust until Germany occupied northern Italy after the overthrow of Fascist leader Benito Mussolini in 1943.
It was reported around the world that in February 2014, 265 copies of the Frank diary and other material related to the Holocaust were found to be vandalized in 31 public libraries in Tokyo, Japan.[40][41] The Simon Wiesenthal Center expressed "its shock and deep concern"[42] and, in response, Chief Cabinet Secretary Yoshihide Suga called the vandalism "shameful." Israel donated 300 copies of Anne Frank's diary to replace the vandalized copies.[43] An anonymous donor under the name of 'Chiune Sugihara' donated two boxes of books pertaining to the Holocaust to the Tokyo central library.[44] After media attention had subsided, police arrested an unemployed man in March.[45] In June, prosecutors decided not to indict the suspect after he was found to be mentally incompetent.[46] Tokyo librarians have reported that Nazi-related books such as the diary and Man's Search for Meaning attract people with mental disorder and are subject to occasional vandalism.[47][better source needed]
As the tide of World War II turned against the Nazis, they began a systematic plan to eliminate or "liquidate" the ghettos they had established, by a combination of mass murder on the spot and transferring the remaining residents to extermination camps. When the Nazis attempted to liquidate the Warsaw Ghetto on April 13, 1943, the remaining Jews fought back in what has become known as the Warsaw Ghetto Uprising. The Jewish resistance fighters held out against the entire Nazi regime for 28 days, longer than many European countries had been able to withstand Nazi conquest.
To those whose knowledge of the Holocaust consists, essentially, of the fact that Hitler killed the Jews, it often comes as a surprise to learn that, in the first seven and a half years of Nazi rule in Germany, he did no such killing: Jews were not deliberately murdered by the Nazi regime until the invasion of the Soviet Union in June 1941. In Karl Schleunes’ famous phrase, there was a “twisted road to Auschwitz,” with a gradual but by no means direct path to continental genocide. For the first few years of Nazi rule in Germany”Hitler came to power in January 1933 as chancellor and consolidated his rule after the death of President von Hindenburg a year later”Nazi policy aimed “merely” at the removal of Jews from positions of authority, especially in the state sector, with such removal constantly reinforced by the totalitarian regime’s propaganda and its police terrorism.
The survey of her manuscripts compared an unabridged transcription of Anne Frank's original notebooks with the entries she expanded and clarified on loose paper in a rewritten form and the final edit as it was prepared for the English translation. The investigation revealed that all of the entries in the published version were accurate transcriptions of manuscript entries in Anne Frank's handwriting, and that they represented approximately a third of the material collected for the initial publication. The magnitude of edits to the text is comparable to other historical diaries such as those of Katherine Mansfield, Anaïs Nin and Leo Tolstoy in that the authors revised their diaries after the initial draft, and the material was posthumously edited into a publishable manuscript by their respective executors, only to be superseded in later decades by unexpurgated editions prepared by scholars.[57]
Her exceptional scholarship has included such insightful books as Beyond Belief: The American Press and the Coming of the Holocaust, 1933-1945 (1986), Denying the Holocaust: The Growing Assault on Truth and Memory (1993), History on Trial: My Day in Court with a Holocaust Denier (2006), The Eichmann Trial (2011), and now, Holocaust: An American Understanding (2016), published as a part of Rutgers University's Key Words in Jewish Studies series.
In October 1939 Hitler signed a "euthanasia decree" backdated to 1 September 1939 that authorized Reichsleiter Philipp Bouhler, the chief of Hitler's Chancellery, and Karl Brandt, Hitler's personal physician, to carry out a program of involuntary "euthanasia"; after the war this program was named Aktion T4.[98] It was named after Tiergartenstraße 4, the address of a villa in the Berlin borough of Tiergarten, where the various organizations involved were headquartered.[99] T4 was mainly directed at adults, but the "euthanasia" of children was also carried out.[100] Between 1939 and 1941, 80,000 to 100,000 mentally ill adults in institutions were killed, as were 5,000 children and 1,000 Jews, also in institutions. In addition there were specialized killing centres, where the deaths were estimated at 20,000, according to Georg Renno, the deputy director of Schloss Hartheim, one of the "euthanasia" centers, or 400,000, according to Frank Zeireis, the commandant of the Mauthausen concentration camp.[101] Overall, the number of mentally and physically handicapped murdered was about 150,000.[102]
Dr. Karski was the contact between the Polish resistance and the Polish government in exile. He repeatedly crossed enemy lines to act as a courier between his occupied nation and the West. Prior to his last departure from Poland, he was smuggled into the Warsaw Ghetto by the Jewish underground in order to witness the horrendous conditions. Asked to tell the story to the rest of the world, he reported on his experience to many world leaders, including American President Franklin Roosevelt.
By the spring of 1942, the Nazis had established six killing centers (death camps) in Poland: Chelmno (Kulmhof), Belzec, Sobibor, Treblinka, Maidanek and Auschwitz. All were located near railway lines so that Jews could be easily transported daily. A vast system of camps (called Lagersystem) supported the death camps. The purpose of these camps varied: some were slave labor camps, some transit camps, others concentration camps and their sub­camps, and still others the notorious death camps. Some camps combined all of these functions or a few of them. All the camps were intolerably brutal.

On November 4, 1943, Globocnik wrote to Himmler from Trieste: "I have, on Oct. 19, 1943, completed Action Reinhard, and closed all the camps." He asked for special medals for his men in recognition of their "specially difficult task". Himmler responded warmly to 'Globos' on November 30, 1943, thanking him for carrying out Operation Reinhard. Also in: Holocaust Encyclopedia. ""Final Solution": Overview".

From this moment on, the Nazi regime adopted hundreds of laws restricting the rights and liberties of the Jewish people. Jews were expelled from the civil service and barred from entering particular professions, stripped of their citizenship, and forbidden from intermarrying or even having a relationship with anyone of “German or German-related blood”.

Historians disagree as to when and how the Nazi leadership decided that the European Jews should be exterminated. The controversy is commonly described as the functionalism versus intentionalism debate which began in the 1960s, and subsided thirty years later. In the 1990s, the attention of mainstream historians moved away from the question of top executive orders triggering the Holocaust, and focused on factors which were overlooked earlier, such as personal initiative and ingenuity of countless functionaries in charge of the killing fields. No written evidence of Hitler ordering the Final Solution has ever been found to serve as a "smoking gun", and therefore, this one particular question remains unanswered.[105]
In response to a typhus epidemic in the women's camp, Mengele cleared one block of six hundred Jewish women and sent them to their deaths in the gas chambers. The building was then cleaned and disinfected, and the occupants of a neighboring block were bathed, de-loused, and given new clothing before being moved into the clean block. This process was repeated until all of the barracks were disinfected. Similar procedures were used for later epidemics of scarlet fever and other diseases, with infected prisoners being killed in the gas chambers. For these actions, Mengele was awarded the War Merit Cross (Second Class with swords) and was promoted in 1944 to First Physician of the Birkenau subcamp.[37]
