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.
Mengele’s crimes had been well documented before the International Military Tribunal (IMT) and other postwar courts. West German authorities issued a warrant for his arrest in 1959, and a request for extradition in 1960. Alarmed by the capture of Adolf Eichmann in Buenos Aires in that same year, Mengele moved to Paraguay and then to Brazil. He spent the last years of his life near Sao Pãolo. In declining health, Mengele suffered a stroke and drowned while swimming at a vacation resort near Bertioga, Brazil, on February 7, 1979. He was buried in a suburb of Sao Pãolo under the fictive name “Wolfgang Gerhard.”
The Majdanek camp served from time to time as a killing site for Jews residing in the Generalgouvernement. In its gas chambers, the SS killed tens of thousands of Jews, primarily forced laborers too weak to work. The SS and police killed at least 152,000 people, mostly Jews, but also a few thousand Roma (Gypsies), in gas vans at the Chelmno killing center about thirty miles northwest of Lodz. In the spring of 1942, Himmler designated Auschwitz II (Auschwitz-Birkenau) as a killing facility. SS authorities murdered approximately one million Jews from various European countries at Auschwitz-Birkenau.
The Nazis used the phrase Lebensunwertes Leben (life unworthy of life) in reference to the disabled and mentally ill.[92] On 14 July 1933, the Law for the Prevention of Hereditarily Diseased Offspring (Gesetz zur Verhütung erbkranken Nachwuchses), the Sterilization Law, was passed, allowing for compulsory sterilization.[93][94] The New York Times reported on 21 December that year: "400,000 Germans to be sterilized".[95] There were 84,525 applications from doctors in the first year. The courts reached a decision in 64,499 of those cases; 56,244 were in favor of sterilization.[96] Estimates for the number of involuntary sterilizations during the whole of the Third Reich range from 300,000 to 400,000.[97]
Holocaust, Hebrew Shoʾah (“Catastrophe”), Yiddish and Hebrew Ḥurban (“Destruction”), the systematic state-sponsored killing of six million Jewish men, women, and children and millions of others by Nazi Germany and its collaborators during World War II. The Germans called this “the final solution to the Jewish question.” Yiddish-speaking Jews and survivors in the years immediately following their liberation called the murder of the Jews the Ḥurban, the word used to describe the destruction of the First Temple in Jerusalem by the Babylonians in 586 bce and the destruction of the Second Temple by the Romans in 70 ce. Shoʾah (“Catastrophe”) is the term preferred by Israelis and the French, most especially after Claude Lanzmann’s masterful 1985 motion picture documentary of that title. It is also preferred by people who speak Hebrew and by those who want to be more particular about the Jewish experience or who are uncomfortable with the religious connotations of the word Holocaust. Less universal and more particular, Shoʾah emphasizes the annihilation of the Jews, not the totality of Nazi victims. More particular terms also were used by Raul Hilberg, who called his pioneering work The Destruction of the European Jews, and Lucy S. Dawidowicz, who entitled her book on the Holocaust The War Against the Jews. In part she showed how Germany fought two wars simultaneously: World War II and the racial war against the Jews. The Allies fought only the World War. The word Holocaust is derived from the Greek holokauston, a translation of the Hebrew word ʿolah, meaning a burnt sacrifice offered whole to God. This word was chosen because in the ultimate manifestation of the Nazi killing program—the extermination camps—the bodies of the victims were consumed whole in crematoria and open fires.
According to psychologist Eva Fogelman “Rescuers’ families nourished an independence of mind and spirit. … In talking with rescuers from all kinds of different homes, I found that one quality above all others was emphasized time and again: a familial acceptance of people who were different. This value was the centrepiece of the childhood of rescuers and became the core from which their rescuer self evolved. From the earliest ages, rescuers were taught by their parents that people are inextricably linked to one another. No one person or group was better than any other. The conviction that all people, no matter how marginal, are of equal value was conveyed to children of both religious and nonreligious households.” Fogelman is the daughter of a Holocaust survivor and founder of the Jewish Foundation for Christian Rescuers.
SS Officer Hosler, under arrest, stands in front of a truck which is loaded with corpses at Belsen concentration camp  © The Final Solution moved into its last stages as Allied forces began to close in on Germany in 1944. The Project Reinhardt camps were razed. A prisoner work-gang called the Blobel Commando began digging up and burning the bodies of those killed by the Einsatzgruppen. Prisoners remaining in Auschwitz and other concentration camps were transported or force-marched to camps within Germany. Hardly fit for such an effort, thousands of prisoners on these death marches succumbed to starvation, exhaustion and cold, or were shot for not keeping up the pace.
The most notorious physician was Josef Mengele, an SS officer who became the Auschwitz camp doctor on 30 May 1943.[54] Interested in genetics[54] and keen to experiment on twins, he would pick out subjects from the new arrivals during "selection" on the ramp, shouting "Zwillinge heraus!" (twins step forward!).[55] They would be measured, killed, and dissected. One of Mengele's assistants said in 1946 that he was told to send organs of interest to the directors of the "Anthropological Institute in Berlin-Dahlem". This is thought to refer to Mengele's academic supervisor, Otmar Freiherr von Verschuer , director from October 1942 of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics in Berlin-Dahlem.[56][55][i] Mengele's experiments included placing subjects in pressure chambers, testing drugs on them, freezing them, attempting to change their eye color by injecting chemicals into children's eyes, and amputations and other surgeries.[59]
What happened next—an avalanche of furies and recriminations lasting years—has lately become the subject of a pair of arresting discussions of the Frank-Levin affair. And if “affair” suggests an event on the scale of the Dreyfus case, that is how Levin saw it: as an unjust stripping away of his rightful position, with implications far beyond his personal predicament. “An Obsession with Anne Frank,” by Lawrence Graver, published by the University of California Press in 1995, is the first study to fashion a coherent narrative out of the welter of claims, counterclaims, letters, cables, petitions, polemics, and rumbling confusions which accompany any examination of the diary’s journey to the stage. “The Stolen Legacy of Anne Frank,” by Ralph Melnick, out just now from Yale, is denser in detail and in sources than its predecessor, and more insistent in tone. Both are accomplished works of scholarship that converge on the facts and diverge in their conclusions. Graver is reticent with his sympathies; Melnick is Levin’s undisguised advocate. Graver finds no villains; Melnick finds Lillian Hellman.
Sometimes the mere presence of German troops in the vicinity was sufficient to spur a massacre. One example is what happened in the Polish village of Jedwabne, where neighbours murdered their Jewish neighbours. For years the massacre was blamed on the Germans, though many Poles likely knew that the local population had turned against its own Jews. In the Baltics, where the Germans were greeted as liberators by some segments of the population, the lure of political independence and the desire to erase any collaboration with the previous Soviet occupiers led nationalist bands to murder local Jews.

In the first phase of the experiments, pairs of twins and persons with inherited anomalies were put at the disposal of Dr. Mengele and subjected to all imaginable specialist medical examinations. They were also photographed, plaster casts were made of their jaws and teeth, and they were toe- and fingerprinted. As soon as these examinations were finished, they were killed with lethal injections of phenol to the heart so that the next phase of the experimentation could begin: autopsies and the comparative analysis of their internal organs.
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]
The rescuers were able to use the national humiliation caused by the German occupation to build limited popular support and help the Jews. They were few in number but ethically and morally strong. Although the number of Jews they saved was small, they provide a beacon of victory for posterity, a victory over the capitulation and collaboration of the majority of their compatriots.

At the end of the war, between 50,000 and 100,000 Jewish survivors were living in three zones of occupation: American, British and Soviet. Within a year, that figure grew to about 200,000. The American zone of occupation contained more than 90 percent of the Jewish displaced persons (DPs). The Jewish DPs would not and could not return to their homes, which brought back such horrible memories and still held the threat of danger from anti-Semitic neighbors. Thus, they languished in DP camps until emigration could be arranged to Palestine, and later Israel, the United States, South America and other countries. The last DP camp closed in 1957 (David S. Wyman, "The United States," in David S. Wyman, ed., The World Reacts to the Holocaust, Baltimore, MD: Johns Hopkins University Press, 1996, pp. 707­10).

The following proclamation was issued by Dr. Ludwig Fischer, the German district governor of Warsaw, on November 10, 1941: "Concerning the Death Penalty for Illegally Leaving Jewish Residental Districts...Any Jew who illegally leaves the designated residential district will be punished by death. Anyone who deliberately offers refuge to such Jews or who aids them in any other manner (i.e., offering a night's lodging, food, or by taking them into vehicles of any kind, etc.) will be subject to the same punishment. Judgment will be rendered by a Special Court in Warsaw. I forcefully draw the attention of the entire population of the Warsaw District to this new decree, as henceforth it will be applied with the utmost severity."
Ruth Elias and her husband had conceived a child while she was a prisoner in the Theresienstadt camp, and when she arrived at Birkenau on a transport of Czech prisoners in December 1943, she was three months pregnant. Ruth passed several selections for the gas chamber even though she was obviously pregnant; she and her husband were assigned to the Czech "family camp." On July 11, 1944, after a selection made by Dr. Mengele, 3,000 prisoners in the Czech family camp, who were not considered fit to work, were sent to the gas chamber, but Ruth passed the selection even though she was in her eighth month of pregnancy. On July 14, 1944, Ruth was sent to Hamburg, Germany to work in clearing rubble from Allied bombing raids.
Of the children involved, only about 200 were alive when the camp was liberated by the Soviet Army on January 27, 1945. These are the children shown so often in documentaries walking between the wires of the Auschwitz I camp. Today they reside all over the world and they seek information on what was done to them. Their files have never been located and what was done to them remains a mystery today.
Several scholars have suggested that the Final Solution began in the newly formed district of Bezirk Bialystok.[48] The German army took over Białystok within days. On Friday, 27 June 1941, the Reserve Police Battalion 309 arrived in the city and set the Great Synagogue on fire with hundreds of Jewish men locked inside.[49] The burning of the synagogue was followed by a frenzy of killings both inside the homes around the Jewish neighbourhood of Chanajki, and in the city park, lasting until night time.[50] The next day, some 30 wagons of dead bodies were taken to mass graves. As noted by Browning, the killings were led by a commander "who correctly intuited and anticipated the wishes of his Führer" without direct orders.[49] For reasons unknown, the number of victims in the official report by Major Weis was cut in half.[50] The next mass shooting of Polish Jews within the newly formed Reichskommissariat Ostland took place in two days of 5–7 August in occupied Pińsk, where over 12,000 Jews died at the hands of Waffen SS,[51] not the Einsatzgruppen.[41] An additional 17,000 Jews perished there in a ghetto uprising crushed a year later with the aid of Belarusian Auxiliary Police.[52]
'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 October 1941 the Nazis began turning the concentration camp at Majdanek into a death camp as well. They then began the construction of killing centres at Bełżec, Treblinka, near Warsaw, and at Sobibór. The first mass gassing of Jews began in Chelmno on 8 December 1941, when the Nazis used gas vans to murder people from the Łódź ghetto. The Nazis also ordered the expansion of the Auschwitz camp complex to increase the capacity for murder.
In the first phase of the experiments, pairs of twins and persons with inherited anomalies were put at the disposal of Dr. Mengele and subjected to all imaginable specialist medical examinations. They were also photographed, plaster casts were made of their jaws and teeth, and they were toe- and fingerprinted. As soon as these examinations were finished, they were killed with lethal injections of phenol to the heart so that the next phase of the experimentation could begin: autopsies and the comparative analysis of their internal organs.

Gerda Schrage was 24 years old when she was sent to Auschwitz-Birkenau in 1944. She had been in hiding in Berlin during the war, until someone betrayed her to the Gestapo and she was arrested. According to Gerda's story, as told in the documentary film "Gerda's Silence," when she arrived at Auschwitz, she was pregnant by a married man with whom she had had an affair while she was in hiding. Her baby died in her arms at Birkenau because Dr. Mengele was conducting yet another cruel experiment and would not allow her to nurse the baby.
The plans to exterminate all the Jews of Europe was formalized at the Wannsee Conference, held at an SS guesthouse near Berlin,[24] on 20 January 1942. The conference was chaired by Heydrich and attended by 15 senior officials of the Nazi Party and the German government. Most of those attending were representatives of the Interior Ministry, the Foreign Ministry, and the Justice Ministry, including Ministers for the Eastern Territories.[25] At the conference, Heydrich indicated that approximately 11,000,000 Jews in Europe would fall under the provisions of the "Final Solution". This figure included not only Jews residing in Axis-controlled Europe, but also the Jewish populations of the United Kingdom and of neutral nations (Switzerland, Ireland, Sweden, Spain, Portugal, and European Turkey).[2] Eichmann's biographer David Cesarani wrote that Heydrich's main purpose in convening the conference was to assert his authority over the various agencies dealing with Jewish issues. "The simplest, most decisive way that Heydrich could ensure the smooth flow of deportations" to death camps, according to Cesarani, "was by asserting his total control over the fate of the Jews in the Reich and the east" under the single authority of the RSHA.[26] A copy of the minutes of this meeting was found by the Allies in March 1947;[27] it was too late to serve as evidence during the first Nuremberg Trial, but was used by prosecutor General Telford Taylor in the subsequent Nuremberg Trials.[28]

The Avenue of the Righteous, a place where trees are planted to commemorate rescuers, was inaugurated on Holocaust Remembrance Day 1962. The following year, a commission chaired by a member of Israel's Supreme Court was set up to decide upon criteria for awarding the Righteous Among the Nations. On February 1, Justice Moshe Landau chaired the commission's first meeting.

As if cold-blooded murder of millions of Jews was not enough, it was done with extreme, perverse cruelty. The victims were packed into cattle trains with standing-room only and without food or water, or heat in the winter, or toilet facilities. Many did not arrive at the camps alive. Those who did arrive at their destination had their heads shaved, with the hair to be used for stuffing mattresses. Stripped of all clothing, most were herded naked into the gas chambers. Dr Johann Kremer, a German SS surgeon, described the gassing of a group of French Jews including 150 boys and girls under the age of 15:
Zeidel had spent the previous two years in German-occupied Vilnius, in the city’s walled-off Jewish ghetto. He’d watched as the Nazis sent first hundreds and then thousands of Jews by train or truck or on foot to a camp in the forest. A small number of people managed to flee the camp, and they returned with tales of what they’d seen: rows of men and women machine-gunned down at close range. Mothers pleading for the lives of their children. Deep earthen pits piled high with corpses. And a name: Ponar.
The forest burst orange with gunfire. “I looked around: Our entire path was filled with people crawling,” Farber has written. “Some jumped up and started running in various directions.” Farber and Dogim cut through the fence and tore off into the woods, with Zeidel and three others in tow. The men ran all night, through rivers, through forests, past villages. After a week, the escapees were deep inside the Rudnitsky Woods. Farber introduced himself to the partisan leader. “Where do you come from?” the man asked.
When she was 17, Amir took a class about the Holocaust. “How did you escape, Papa?” she remembers asking afterward. He agreed to explain, but what he recounted were mostly technical details: the size of the bunker, the number of bodies consumed by the flames. He explained that in addition to the five men who had fled with him to the Rudnitsky Woods, six other members of the Burning Brigade had survived the escape. The rest had perished.
The Nazi invasion of the Soviet Union codenamed Operation Barbarossa, which commenced on 22 June 1941, set in motion a "war of destruction" which quickly opened the door to systematic mass murder of European Jews.[30] For Hitler, Bolshevism was merely "the most recent and most nefarious manifestation of the eternal Jewish threat".[31] On 3 March 1941, Wehrmacht Joint Operations Staff Chief Alfred Jodl repeated Hitler's declaration that the "Jewish-Bolshevik intelligentsia would have to be eliminated" and that the forthcoming war would be a confrontation between two completely opposing cultures.[32] In May 1941, Gestapo leader Heinrich Müller wrote a preamble to the new law limiting the jurisdiction of military courts in prosecuting troops for criminal actions because: "This time, the troops will encounter an especially dangerous element from the civilian population, and therefore, have the right and obligation to secure themselves."[33]

By the end of September, the SS had started to develop plans to deport Jews to newly invaded Poland: the first steps towards the systematic murder that would follow. In Poland itself, thousands of Poles and Jews were rounded up and shot, early indications of the systematic murder that would follow. Alongside this, Hitler approved a new programme of euthanasia to exterminate the handicapped and mentally ill.
Many healthy, young strong Jews were not killed immediately. The Germans' war effort and the “Final Solution” required a great deal of manpower, so the Germans reserved large pools of Jews for slave labor. These people, imprisoned in concentration and labor camps, were forced to work in German munitions and other factories, such as I.G. Farben and Krupps, and wherever the Nazis needed laborers. They were worked from dawn until dark without adequate food and shelter. Thousands perished, literally worked to death by the Germans and their collaborators.
Similarly, in Ordinary Men (1992), Christopher Browning examined the deeds of German Reserve Police Battalion 101 of the Ordnungspolizei ("order police"), used to commit massacres and round-ups of Jews, as well as mass deportations to the death camps. The members of the battalion were middle-aged men of working-class background from Hamburg, who were too old for regular military duty. They were given no special training. During the murder of 1,500 Jews from Józefów in Poland, their commander allowed them to opt out of direct participation. Fewer than 12 men out of a battalion of 500 did so. Influenced by the Milgram experiment on obedience, Browning argued that the men killed out of peer pressure, not bloodlust.[471]

Because they refused to pledge allegiance to the Nazi party or serve in the military, Jehovah's Witnesses were sent to concentration camps, where they were identified by purple triangles and given the option of renouncing their faith and submitting to the state's authority.[447] The United States Holocaust Memorial Museum estimates that between 2,700 and 3,300 were sent to the camps, where 1,400 died;[411] in The Holocaust Encyclopedia (2001), Sybil Milton estimates that 10,000 were sent and 2,500 died.[412] According to German historian Detlef Garbe, "no other religious movement resisted the pressure to conform to National Socialism with comparable unanimity and steadfastness."[448]

These programmes are best seen as a series of linked genocides, each having its own history, background, purpose and significance in the Nazi scheme of things. The Holocaust was the biggest of the killing programmes and, in certain important ways, different from the others. The Jews figured in Nazi ideology as the arch-enemy of the 'Aryan race', and were targeted not merely for terror and repression but for complete extinction. The Nazis failed in this aim because they ran out of time, but they pursued it fanatically until their defeat in 1945. The Holocaust led to widespread public awareness of genocide and to modern efforts to prevent it, such as the 1948 UN Convention on Genocide.

4 out of 5 stars to The Diary of a Young Girl, written during the 1940s by Anne Frank. Many are first exposed to this modern-day classic during their middle or high school years, as a way to read a different type of literature from that of an ordinary novel. In this diary, young Anne express her thoughts (both positive and negative) over a two-year period during which her family and friends are in hiding during World War II and the Holocaust. For most of us, this is one of the few ...more

Browning describes the creation of the extermination camps, which were responsible for the largest number of deaths in the Final Solution, as bringing together three separate developments within the Third Reich: the concentration camps which had been established in Germany since 1933; an expansion of the gassing technology of the Nazi euthanasia programme to provide killing mechanism of greater efficiency and psychological detachment; and the creation of "factories of death" to be fed endless streams of victims by mass uprooting and deportation that utilized the experience and personnel from earlier population resettlement programmes—especially the HSSPF and Adolf Eichmann's RSHA for "Jewish affairs and evacuations".[115]
When Hitler came to power legally on January 30, 1933, as the head of a coalition government, his first objective was to consolidate power and to eliminate political opposition. The assault against the Jews began on April 1 with a boycott of Jewish businesses. A week later the Nazis dismissed Jews from the civil service, and by the end of the month the participation of Jews in German schools was restricted by a quota. On May 10 thousands of Nazi students, together with many professors, stormed university libraries and bookstores in 30 cities throughout Germany to remove tens of thousands of books written by non-Aryans and those opposed to Nazi ideology. The books were tossed into bonfires in an effort to cleanse German culture of “un-Germanic” writings. A century earlier Heinrich Heine—a German poet of Jewish origin—had said, “Where one burns books, one will, in the end, burn people.” In Nazi Germany the time between the burning of Jewish books and the burning of Jews was eight years.
In the years of Nazi rule before World War II, policies of persecution and segregation targeting German Jews focused on the goal of expulsion. After the Nazi party seized power in 1933, state-sponsored racism generated anti-Jewish legislation, boycotts, "Aryanization," and massive street violence, as in the Kristallnacht (commonly known as the "Night of Broken Glass") pogroms. With all of these measures, the Nazi leaders sought to drive the Jews out of Germany by systematically isolating them from German society and by eliminating them from the German economy, removing any opportunity for them to make a living in Germany.
After the Wannsee Conference in January 1942, the Nazis began the systematic deportation of Jews from all over Europe to six extermination camps established in former Polish territory -- Chelmno , Belzec, Sobibor, Treblinka, Auschwitz-Birkenau, and Majdanek. Extermination camps were killing centers designed to carry out genocide. About three million Jews were gassed in extermination camps.
A victim of Nazi medical experimentation. A victim's arm shows a deep burn from phosphorus at Ravensbrueck, Germany, in November of 1943. The photograph shows the results of a medical experiment dealing with phosphorous that was carried out by doctors at Ravensbrueck. In the experiment, a mixture of phosphorus and rubber was applied to the skin and ignited. After twenty seconds, the fire was extinguished with water. After three days, the burn was treated with Echinacin in liquid form. After two weeks the wound had healed. This photograph, taken by a camp physician, was entered as evidence during the Doctors Trial at Nuremberg. #
Half a year later, Harel was replaced by Meir Amit, who ordered the Mossad to “stop chasing after ghosts from the past and devote all our manpower and resources to threats against the security of the state.” He mandated that the agency deal with Nazis “only to the extent it is able to do so, in addition to its principal missions” and as long as “it doesn’t impinge on the other operations.”
Freund and I walked the path of the tunnel, over the large hummock of earth, out toward the surrounding pines. Not such a long distance on foot, perhaps, but positively heroic when one considered that it had been dug, night after night, by chained men who had spent their daylight hours laboring at their unthinkable task, subsisting on nothing more than gruel.

The Nazis established ghettos in occupied Poland. Polish and western European Jews were deported to these ghettos. During the German invasion of the Soviet Union in 1941, mobile killing squads (Einsatzgruppen) began killing entire Jewish communities. The methods used, mainly shooting or gas vans, were soon regarded as inefficient and as a psychological burden on the killers.
In the immediate postwar period, Mengele was in US custody. Unaware that Mengele's name already stood on a list of wanted war criminals, US officials quickly released him. From the summer of 1945 until spring 1949, using false papers, Mengele worked as a farmhand near Rosenheim, Bavaria. His prosperous family then aided his emigration to South America. He settled in Argentina.
