Ghettos were intended to be temporary until the Jews were deported to other locations, which never happened. Instead, the inhabitants were sent to extermination camps. The ghettos were, in effect, immensely crowded prisons serving as instruments of "slow, passive murder."[216] Though the Warsaw Ghetto contained 30% of Warsaw's population, it occupied only 2.5% of the city's area, averaging over 9 people per room.[217] Between 1940 and 1942, starvation and disease, especially typhoid, killed many in the ghettos.[218] Over 43,000 Warsaw ghetto residents, or one in ten of the total population, died in 1941;[219] in Theresienstadt, more than half the residents died in 1942.[216]
Below are figures for the number of Jews murdered in each country that came under German domination. They are estimates, as are all figures relating to Holocaust victims. The numbers given here for Czechoslovakia, Hungary and Romania are based on their territorial borders before the 1938 Munich agreement. The total number of six million Jews murdered during the Holocaust, which emerged from the Nuremberg trials, is also an estimate. Numbers have ranged between five and seven million killed.
There are different methods of execution. People are shot by firing squads, killed by an "air hammer", and poisoned by gas in special gas chambers. Prisoners condemned to death by the Gestapo are murdered by the first two methods. The third method, the gas chamber, is employed for those who are ill or incapable of work and those who have been brought in transports especially for the purpose/Soviet prisoners of war, and, recently Jews.[333]
Several resistance groups were formed, such as the Jewish Combat Organization in the Warsaw Ghetto and the United Partisan Organization in Vilna.[310] Over 100 revolts and uprisings occurred in at least 19 ghettos and elsewhere in Eastern Europe. The best known is the Warsaw Ghetto Uprising of 1943, when around 1,000 poorly armed Jewish fighters held the SS at bay for four weeks.[311][q] During a revolt in Treblinka on 2 August 1943, inmates killed five or six guards and set fire to camp buildings; several managed to escape.[316][317] In the Białystok Ghetto on 16 August 1943, Jewish insurgents fought for five days when the Germans announced mass deportations.[318] On 14 October 1943, Jewish prisoners in Sobibór, including Jewish-Soviet prisoners of war, attempted an escape,[319] killing 11 SS officers and a couple of Ukrainian camp guards.[320] Around 300 escaped, but 100 were recaptured and shot.[321] On 7 October 1944, 300 Jewish members of the Sonderkommando at Auschwitz, who learned they were about to be killed, attacked their guards and blew up crematorium IV. Three SS officers were killed, one of whom was stuffed into an oven, as was a German kapo. None of the Sonderkommando rebels survived the uprising.[322]
The pursuit resumed with a vengeance. In 1982, the agency even considered abducting a 12-year-old boy and threatening to take his life unless his father, Hans-Ulrich Rudel, a devoted Nazi and a childhood friend of Mengele’s, gave them the information that could lead to his capture. (In the end, Rudel died before the Mossad decided whether to go through with the operation.)
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.
Approximately a half million Gypsies (a dark-skinned, Caucasian ethnic group targeted by the Nazis) were murdered out of approximately 1.6 million who were living in Europe. The Gypsies in Germany and the occupied territories of the German War machine were subjected to many of the same persecutions as the Jews: restrictive, discriminatory laws, isolation and internment, and mass executions at their camp sites, in labor camps and death camps.
Following the invasion of the Soviet Union in June 1941, Einsatzgruppen and, later, militarized battalions of Order Police officials, moved behind German lines to carry out mass-murder operations against Jews, Roma, and Soviet state and Communist Party officials. German SS and police units, supported by units of the Wehrmacht and the Waffen SS, murdered more than a million Jewish men, women, and children, and hundreds of thousands of others.

More camps opened in the spring and summer of 1942, when the Nazis began systematically clearing the ghettos in Poland and rounding up Jews in western Europe for 'deportation to the East'. The killing of the Polish Jews, code-named 'Project Reinhardt', was carried out in three camps: Treblinka, near Warsaw (850,000 victims); Belzec, in south-eastern Poland (650,000 victims); and Sobibor, in east-central Poland (250,000 victims). Some Jews from western Europe were sometimes taken to these camps as well, but most were killed at the biggest and most advanced of the death camps, Auschwitz.
'Righteous Gentiles' is the phrase used for those non-Jews who risked their lives to save Jews during the Holocaust. At Yad Vashem Museum in Jerusalem, over 11,000 'Righteous Gentiles' are honored; almost 5,000 are Polish. What follows are profiles and oral histories of ten Polish rescuers of Jews. Their stories reveal what transforms people from indifferent bystanders into heroic saviors
In the eyes of the world, we’re doomed, but if after all this suffering, there are still Jews left, the Jewish people will be held up as an example. Who knows, maybe our religion will teach the world and all the people in it about goodness, and that’s the reason, the only reason, we have to suffer. . . . God has never deserted our people. Through the ages Jews have had to suffer, but through the ages they’ve gone on living, and the centuries of suffering have only made them stronger.

Racial-Morphological Examinations of the Anterior Portion of the Lower Jaw in Four Racial Groups. This dissertation, completed in 1935 and first published in 1937, earned him a PhD in anthropology from Munich University. In this work Mengele sought to demonstrate that there were structural differences in the lower jaws of individuals from different ethnic groups, and that racial distinctions could be made based on these differences.[7][121]

The term righteous gentile is a reference to the term 'Righteous Among the Nations' that is a honour bestowed by Yad Vashem. Gushee's work is a study of these people, the (very) few in number who risked personal harm to selflessly assist Jews from persecution. This book is full of accounts of such persons, some who succeeded and some who failed. These are extremely challenging, particularly when faced with the question 'what would I do in such a situation?' knowing that what I hope I would do and what I do may not be synonymous. In studying such persons Gushee presents a good overview of the types of people who were in the minority and were righteous Gentiles, including conclusions on the extent religion played a role in their actions.
Of all the aspects of Mengele’s character which are of interest, his research on twins is the focus of the C.A.N.D.L.E.S. organization. Beginning in 1944, twins were selected and placed in special barracks. Some of those selected - like Irene and Rene Guttman were already in the camp. Others like Eva and Miriam Mozes were selected on the ramp and placed in the twins barracks. It is believed that Mengele had worked with twins under Verschuer at the University of Frankfurt. Auschwitz offered Mengele unlimited number of specimens where twins could be studied at random. According to Dr. Miklos Nyiszli in Auschwitz: A Doctor's Eyewitness Account, twins provided the perfect experimental specimens. One could serve as a control while the other endured the experiments. It was well known in the camp that when a twin went to the infirmary, (s)he never returned and that the other twin disappeared too (Eva Mozes Kor, Echoes from Auschwitz). Nyiszli describes the shots of phenol which were used to kill the second twin.
Dan Stone, a specialist in the historiography of the Holocaust, lists ethnic Poles, Ukrainians, Soviet prisoners of war, Jehovah's Witnesses, black Germans, and homosexuals as among the groups persecuted by the Nazis; he writes that the occupation of eastern Europe can also be viewed as genocidal. But the German attitude toward the Jews was different in kind, he argues. The Nazis regarded the Jews not as racially inferior, deviant, or enemy nationals, as they did other groups, but as a "Gegenrasse: a 'counter-race', that is to say, not really human at all". The Holocaust, for Stone, is therefore defined as the genocide of the Jews, although he argues that it cannot be "properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans".[d] Donald Niewyk and Francis Nicosia, in The Columbia Guide to the Holocaust (2000), favour a definition that focuses on the Jews, Roma, and Aktion T4 victims: "The Holocaust—that is, Nazi genocide—was the systematic, state-sponsored murder of entire groups determined by heredity. This applied to Jews, Gypsies, and the handicapped."[33]

One of the clearest examples of Hitler’s single-minded (and seemingly suicidal) desire to rid the world of the Jews can be seen in the extermination of the Jews of Hungary. Until March of 1944, the Hungarian government had refused to allow the deportation of Hungarian Jews. It March 1944 the Germans occupied Hungary and by mid May ( two weeks before D Day) the mass deportations to Auschwitz. The Nazi leadership worked with particular intensity. The Soviet army was rapidly approaching Hungary and the Germans knew that they were going to lose the war. But there was no way that Hitler could allow such a large Jewish community to survive. He diverted trains that were badly needed to transport more soldiers to the Russian front just to send more Jews to Auschwitz. To him, the greater enemy was the Jew.

All these appropriations, whether cheaply personal or densely ideological, whether seen as exalting or denigrating, have contributed to the conversion of Anne Frank into usable goods. There is no authorized version other than the diary itself, and even this has been brought into question by the Holocaust denial industry—in part a spinoff of the Anne Frank industry—which labels the diary a forgery. One charge is that Otto Frank wrote it himself, to make money. (Scurrilities like these necessitated the issuance, in 1986, of a Critical Edition by the Netherlands State Institute for War Documentation, including forensic evidence of handwriting and ink—a defensive hence sorrowful volume.)
At each of the death camps, special squads of Jewish slave laborers called Sonderkommandos were utilized to untangle the victims and remove them from the gas chamber. Next they extracted any gold fillings from teeth and searched body orifices for hidden valuables. The corpses were disposed of by various methods including mass burials, cremation in open fire pits or in specially designed crematory ovens such as those used at Auschwitz. All clothing, money, gold, jewelry, watches, eyeglasses and other valuables were sorted out then shipped back to Germany for re-use. Women's hair was sent to a firm in Bavaria for the manufacture of felt.
The Netherlands Institute for War Documentation commissioned a forensic study of the manuscripts after the death of Otto Frank in 1980. The material composition of the original notebooks and ink, and the handwriting found within them and the loose version were extensively examined. In 1986, the results were published: The handwriting attributed to Anne Frank was positively matched with contemporary samples of Anne Frank's handwriting, and the paper, ink, and glue found in the diaries and loose papers were consistent with materials available in Amsterdam during the period in which the diary was written.[56]

Finland was pressured in 1942 to hand over its 150–200 non-Finnish Jews to Germany. After opposition from the government and public, eight non-Finnish Jews were deported in late 1942; only one survived the war.[173] Japan had little antisemitism in its society and did not persecute Jews in most of the territories it controlled. Jews in Shanghai were confined, but despite German pressure they were not killed.[174]
Mengele's eye experiments included attempts to change the eye color by injecting chemicals into the eyes of living subjects, and he killed people with heterochromatic eyes so that the eyes could be removed and sent to Berlin for study.[53] His experiments on dwarfs and people with physical abnormalities included taking physical measurements, drawing blood, extracting healthy teeth, and treatment with unnecessary drugs and X-rays.[3] Many of his victims were dispatched to the gas chambers after about two weeks, and their skeletons sent to Berlin for further analysis.[54] Mengele sought out pregnant women, on whom he would perform experiments before sending them to the gas chambers.[55] Witness Vera Alexander described how he sewed two Romani twins together, back to back, in a crude attempt to create conjoined twins;[50] both children died of gangrene after several days of suffering.[56]
