The Holocaust, also known as the Shoah,[b] was a genocide during World War II in which Nazi Germany, aided by local collaborators, systematically murdered some six million European Jews—around two-thirds of the Jewish population of Europe—between 1941 and 1945.[a][c] Jews were targeted for extermination as part of a larger event during the Holocaust era, in which Germany and its collaborators persecuted and murdered other groups, including Slavs (chiefly ethnic Poles, Soviet prisoners of war, and Soviet citizens), the Roma, the "incurably sick", political and religious dissenters such as communists and Jehovah's Witnesses, and gay men.[d] Taking into account all the victims of Nazi persecution, the death toll rises to over 17 million.[3]
Unlike concentration camps, death camps had no barracks to house prisoners, other than those for workers at the camps. In order to process the murder of thousands of people, great pains were taken to deceive the victims concerning their fate. Jews deported from ghettos and concentration camps to the death camps were unaware of what they were facing. The Nazi planners of the operation told the victims that they were being resettled for labor, issued them work permits, told them to bring along their tools and to exchange their German marks for foreign currency. Food was also used to coax starving Jews onto the trains. Once the trains arrived at the death camps, trucks were available to transport those who were too weak to walk directly to the gas chambers. The others were told that they would have to be deloused and enter the baths. The victims were separated by sex and told to remove their clothes. The baths were in reality the gas chambers. The shower heads in the baths were actually the inlets for poison gas. At Auschwitz, the gas chambers held 2,000 people at a time. With the introduction of a cyanide-based gas called Zyklon B, all 2,000 occupants could be killed in five minutes. As a result of this technological “advancement,” Auschwitz was able to “process” the death of 12,000 victims daily. Before the bodies were removed by workers with gas masks and burned in crematoria, the teeth of the victims were stripped for gold, which was melted down and shipped back to Germany. Innocent victims were exploited and desecrated to a degree unknown in human history.
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.
But for all that this book has been set up as a work of Christian ethics and in that I think the book fails there is next to no specifically Christian ethical content. Why should one risk the lives of oneself and one's family for a stranger? Is the fact that so many didn't amount, as Eliezer Berkovits put it to "the moral bankruptcy of Christian civilization and the spiritual bankruptcy of Christian religion"? On these points Gushee is silent. And so, this book does not offer an account of the moral obligation the disciple of Christ owe to the persecuted Jew in particular or the persecuted stranger in general. It does however ask a very important question, and that alone makes this a book worth taking seriously.

Frank apparently began an entry on September 28, 1942, then ruined the pages. “I’ll use this spoiled page to write down ‘dirty’ jokes,” she wrote—then listed four, along with an imagined lesson on sex education and some information on prostitutes. “At the end she explicitly names her father, Otto, who had been in Paris and saw houses with prostitutes,” the Anne Frank Housewrites.
German communists, socialists and trade unionists were among the earliest opponents of the Nazis[443] and among the first to be sent to concentration camps.[444] Before the invasion of the Soviet Union, Hitler issued the Commissar Order, which ordered the execution of all political commissars and Communist Party members captured.[445] Nacht und Nebel ("Night and Fog") was a directive of Hitler in December 1941, resulting in the disappearance of political activists throughout the German-occupied territories.[446]
Relying on a surveying device known as a total station—the tripod-mounted optical instrument employed by construction and road crews—Reeder set about measuring minute elevation changes across the land, searching for subtle gradations and anomalies. He zeroed in on a hummock that looked like the earthen side of a bunker, long since overgrown with moss and foliage, and roughly 100 feet away, a telltale dip in the earth.
The roots of Hitler’s particularly virulent brand of anti-Semitism are unclear. Born in Austria in 1889, he served in the German army during World War I. Like many anti-Semites in Germany, he blamed the Jews for the country’s defeat in 1918. Soon after the war ended, Hitler joined the National German Workers’ Party, which became the National Socialist German Workers’ Party (NSDAP), known to English speakers as the Nazis. While imprisoned for treason for his role in the Beer Hall Putsch of 1923, Hitler wrote the memoir and propaganda tract “Mein Kampf”(My Struggle), in which he predicted a general European war that would result in “the extermination of the Jewish race in Germany.”
Eichmann received various levels of cooperation from each of the various occupied governments. But in countries such as Holland, Belgium, Albania, Denmark, Finland and Bulgaria, some Jews were saved from their deaths by the action of the sympathetic populace and government officials. Denmark’s government and populace were exemplary in their heroism in saving Jews. In other countries such as Poland, Greece, France, and Yugoslavia, the deportation of Jews to the death camps was facilitated by the cooperation of the government.
Romania implemented anti-Jewish measures in May and June 1940 as part of its efforts towards an alliance with Germany. Jews were forced from government service, pogroms were carried out, and by March 1941 all Jews had lost their jobs and had their property confiscated.[169] After Romania joined the invasion of the Soviet Union in June 1941, at least 13,266 Jews were killed in the Iași pogrom,[170] and Romanian troops carried out massacres in Romanian-controlled territory, including the Odessa massacre of 20,000 Jews in Odessa in late 1941. Romania also set up concentration camps under its control in Transnistria, where 154,000–170,000 Jews were deported from 1941 to 1943.[169]
After the Nuremberg war crimes trials finished, the United States spearheaded the effort to end genocide and become a champion for the prevention of crimes against humanity. The U.S. pushed for greater international effort, helping to draft the 1948 Genocide Convention. President Harry Truman addressed Congress urging the Convention’s passage. He stressed the role the United States had to play in “outlawing the world-shocking crime of genocide.”
The SS used Sonderkommandos (Jewish slave laborers) during the gassing process to usher people in the undressing room and to clean up the gas chamber afterwards. One such survivor recalled the scene at Auschwitz: "There were all sorts of reactions from all sorts of people. There were disabled people. They would take out their war service cards showing that they had fought in the First World War with all kinds of distinctions and medals which they had from that time. They shouted, what's this? We fought for Germany. Now they're going to burn us, to kill us. This is impossible. We protest against such a thing. But everyone just laughed at them. Because they didn't take it seriously, these SS men. They laughed at the whole thing."
After Germany’s loss in WWI, the Treaty of Versailles punished Germany by placing tough restrictions on the country. The treaty made Germany take full responsibility for the war, reduced the extent of German territory, severely limited the size and placement of their armed forces, and forced Germany to pay the allied powers reparations. These restrictions not only increased social unrest but, combined with the start of the Great Depression, collapsed the German economy as inflation rose alongside unemployment.
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]

It might be noted that, to a surprising extent, much about Hitler’s precise knowledge of the Holocaust remains unclear. For instance, we do not know if Hitler ever saw photographs or newsreels of the killing process, or, indeed, just how comprehensive and brutally frank were Himmler’s reports to Hitler. We have agendas of face-to-face meetings between Hitler and Himmler, at which the Holocaust was to be discussed, but no memorializations or minutes of such meetings. Most of the senior Nazis who were tried at Nuremberg in 1945-1946 (few of whom had any immediate involvement in the killing of Jews) had apparently never seen photographic evidence of the horrors of the concentration camps until their trials; they appeared to be genuinely shocked when newsreels of Belsen and Buchenwald were shown to the court.
Upon arrival at a camp in mates were stripped of their clothes and shaved of all their body hair. Then they were given a shower, disinfected and given a uniform. each step was used to dehumanize prisoners, both physically and emotionally. Prisoners were then given a number. At Auschwitz the number was tattooed on their arm. Those who the Nazis thought were unable to work were token to what they called showers. The Nazis said to these prisoners who were about to meet their deaths it was to freshen up a bit after their long journey. Instead of water Zyklon B, developed to kill rodents, closed in on them. Death Did not usually come quickly but rather slowly. Most of the walls of the death chambers had scratch marks to show how victims tried to dig themselves out. The purpose of these cams were to kill huge amounts of Jews a day. Camps had been in Germany for years. These were the places  were tons of Jews had been murdered. Once at the camps selected people would work the others were gassed. Before being gassed they forced to march to the sound of music. An important camp was Treblinka. It was established for slave labor In 1941, but in 1942 it became a death camp. By may 1943 the population of Warsaw had been transported to Treblinka and other camps. By July 11, 1944 800,000 Jews had been murdered in Treblinkia. Unlike Treblinkia, Chelmno, Sobibor, and Balzac which were made to kill Jews. Maidanek and Auschwitz had a work camp attached. Upon arrival at these two camps a selection was made. 10% of the new arrivals would escape immediate gassing.   
The reference to Haman’s wife Zeresh, who plays only a supporting role in the book of Esther, can be chalked up to poetic license—a female villain in counterpoint to the story’s heroine. But what of Harbonah, a decidedly minor character mentioned only once in the entire book, and whose appearance in the poem’s final verse breaks the stanza’s metrical form and rhyme scheme? And what of the epithet “to be remembered for the good”?
"Despite decades of Holocaust studies and even mass media attention (e.g., Shindler's List), no full-length treatment of the Righteous Gentiles has appeared in and for Christian ethics. Who were these people? Why did they do what they did? What kind of Christianity was theirs, if any? How do we assess them, from a moral point of view? And what does it all mean for Christian ethics? Finally, with this book the lacuna has been filled, and David Gushess does it so very, very well." ―Larry L. Rasmussen, Union Theological Seminary
The same year, the Mossad hoped to tap phone conversations between Mengele and his son, Rolf, who was living in West Berlin. The two were born on the same day, and the Israelis hoped they would call each other to say happy birthday. Cold War Berlin was inundated with spies, and the Mossad preferred when possible not to work there. But they calculated that “this may be the last opportunity” to hear from Mengele. Israeli operatives installed listening devices in Rolf’s home and office, and in his phones.
15-year-old Anne looked very critically at the texts written by 13-year-old Anne. She gave to the texts written during the first six months in hiding an especially thorough going-over. There, the differences between the original diary and Anne's rewritten version are the greatest. Since the original diary letters from 1943 have not survived, we do not know anything about them. It is noteworthy that in The Secret Annex, Anne left out her notes about her love for Peter and her vicious remarks about her mother, such as 'my mother is in most things an example to me, but then an example of precisely how I shouldn’t do things.'

After the U.S. government refused to permit the passenger’s refuge, the St. Louis left Cuba for Europe. The St. Louis sailed so close to Florida that they could see the lights of Miami. The passengers were able to find refuge in other European countries so they didn’t have to return to Germany. Great Britain took 288, the Netherlands admitted 181; Belgium took 214, and 224 passengers found temporary refuge in France. When  Germany invaded Western Europe, 532 of the original passengers were trapped. Just over half survived the Holocaust.

There are two versions of the diary written by Anne Frank. She wrote the first version in a designated diary and two notebooks (version A), but rewrote it (version B) in 1944 after hearing on the radio that war-time diaries were to be collected to document the war period. Version B was written on loose paper, and is not identical to Version A, as parts were added and others omitted.[22]
There is no postwar institution specializing in either World War II or the Holocaust that has collected systematic data about the righteous or about Christian-Jewish relations during the war years. Postwar historiography has given scant attention to this subject, except for biographies of heroes like Raoul Wallenberg in Budapest. Individual episodes are recorded in numerous published memoirs or hidden within the histories of the Jewish communities under German occupation. Others are found in some survivor testimonies, oral histories, and depositions.
By late 1938, the Nazis could claim an impressive series of successes. Germany had staged the 1936 Olympics, annexed Austria and part of Czechoslovakia, and was in the midst of a strong economic recovery fuelled by rearmament. These triumphs had increased the Nazis' popularity and their confidence. President Hindenburg had died and all opposition parties had been abolished. The last conservatives in the cabinet had been replaced by Nazis. The way was clear for radical action.
In May 2018, Frank van Vree, the director of the Niod Institute along with others, discovered some unseen excerpts from the diary that Anne had previously covered up with a piece of brown paper. The excerpts discuss sexuality, prostitution, and also include jokes Anne herself described as "dirty" that she heard from the other residents of the Secret Annex and elsewhere. Van Vree said "anyone who reads the passages that have now been discovered will be unable to suppress a smile", before adding, "the 'dirty' jokes are classics among growing children. They make it clear that Anne, with all her gifts, was above all an ordinary girl".[38]
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.
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.
One day this past fall I walked the grounds of the Ponar forest with Freund­ and a couple of his colleagues, who had recently completed a surveying project of the area. Snow had been forecast, but by late morning the only precipitation was icy rain, driven sideways by the wind. The forest was mostly empty, save for a group of ten Israelis who had arrived that morning; they all had family from Vilnius, one of the men explained, and were honoring them by visiting local Holocaust sites.

In the final months of the war, SS guards moved camp inmates by train or on forced marches, often called “death marches,” in an attempt to prevent the Allied liberation of large numbers of prisoners. As Allied forces moved across Europe in a series of offensives against Germany, they began to encounter and liberate concentration camp prisoners, as well as prisoners en route by forced march from one camp to another. The marches continued until May 7, 1945, the day the German armed forces surrendered unconditionally to the Allies.

Responding with alarm to Hitler’s rise, the Jewish community sought to defend their rights as Germans. For those Jews who felt themselves fully German and who had patriotically fought in World War I, the Nazification of German society was especially painful. Zionist activity intensified. “Wear it with pride,” journalist Robert Weltsch wrote in 1933 of the Jewish identity the Nazis had so stigmatized. Religious philosopher Martin Buber led an effort at Jewish adult education, preparing the community for the long journey ahead. Rabbi Leo Baeck circulated a prayer for Yom Kippur (the Day of Atonement) in 1935 that instructed Jews on how to behave: “We bow down before God; we stand erect before man.” Yet while few, if any, could foresee its eventual outcome, the Jewish condition was increasingly perilous and was expected to worsen.

Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million.[400] Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories.[401][402] Of Poland's 3.3 million Jews, about 90 percent were killed.[369] Many more died in the ghettos of Poland before they could be deported.[403] The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews.[394] At Auschwitz-Birkenau the Jewish death toll was 1.1 million;[286][404] Treblinka 870,000–925,000;[405] Bełżec 434,000–600,000;[406][287] Chełmno 152,000–320,000;[407][288] Sobibór 170,000–250,000;[408][291] and Majdanek 79,000.[289]

The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as millions of others, including Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler’s “final solution”–now known as the Holocaust–came to fruition under the cover of world war, with mass killing centers constructed in the concentration camps of occupied Poland.
The British and American governments were reluctant to publicize the intelligence they had received. A BBC Hungarian Service memo, written by Carlile Macartney, a BBC broadcaster and senior Foreign Office adviser on Hungary, stated in 1942: "We shouldn't mention the Jews at all." The British government's view was that the Hungarian people's antisemitism would make them distrust the Allies if Allied broadcasts focused on the Jews.[346] The US government similarly feared turning the war into one about the Jews; antisemitism and isolationism were common in the US before its entry into the war.[347] Although governments and the German public appear to have understood what was happening, it seems the Jews themselves did not. According to Saul Friedländer, "[t]estimonies left by Jews from all over occupied Europe indicate that, in contradistinction to vast segments of surrounding society, the victims did not understand what was ultimately in store for them." In Western Europe, he writes, Jewish communities seem to have failed to piece the information together, while in Eastern Europe, they could not accept that the stories they heard from elsewhere would end up applying to them too.[348]
Anne’s childhood, by contrast, fell into shadows almost immediately. She was not yet four when the German persecutions of Jews began, and from then until the anguished close of her days she lived as a refugee and a victim. In 1933, the family fled from Germany to Holland, where Frank had commercial connections, and where he established a pectin business. By 1940, the Germans had occupied the Netherlands. In Amsterdam, Jewish children, Anne among them, were thrown out of the public-school system and made to wear the yellow star. At thirteen, on November 19, 1942, already in hiding, Anne Frank could write:
The Nazi concentration camps were established beginning in 1933 for the purpose of imprisoning political opponents. After the “Night of the Long Knives” (see Chapter 8, page 65), authority and management of the concentration camps was turned over to the S.S. The S.S. expanded the concentration camp system, and used these facilities to warehouse other “undesirables,” including hundreds of thousands of Jews. Dachau, Buchenwald and Sachsenhausen were among the first concentration camps built by the Nazis near Munich, Weimar, and Berlin respectively.
Within one week from the start of Operation Barbarossa, Heydrich issued an order to his Einsatzkommandos for the on-the-spot execution of all Bolsheviks, interpreted by the SS to mean all Jews. One of the first indiscriminate massacres of men, women, and children in Reichskommissariat Ukraine took the lives of over 4,000 Polish Jews in occupied Łuck on 2–4 July 1941, murdered by Einsatzkommando 4a assisted by the Ukrainian People's Militia.[55] Formed officially on 20 August 1941, the Reichskommissariat Ukraine – stretching from prewar east-central Poland to Crimea – had become operational theatre of the Einsatzgruppe C. Within the Soviet Union proper, between 9 July 1941 and 19 September 1941 the city of Zhytomyr was made Judenfrei in three murder operations conducted by German and Ukrainian police in which 10,000 Jews perished.[41] In the Kamianets-Podilskyi massacre of 26–28 August 1941 some 23,600 Jews were shot in front of open pits (including 14,000–18,000 people expelled from Hungary).[41][56] After an incident in Bila Tserkva in which 90 small children left behind had to be shot separately, Blobel requested that Jewish mothers hold them in their arms during mass shootings.[57][58] Long before the conference at Wannsee, 28,000 Jews were shot by SS and Ukrainian military in Vinnytsia on 22 September 1941, followed by the 29 September massacre of 33,771 Jews at Babi Yar.[41][59] In Dnipropetrovsk, on 13 October 1941 some 10,000–15,000 Jews were shot.[60] In Chernihiv, 10,000 Jews were put to death and only 260 Jews were spared.[60] In mid-October, during the Krivoy-Rog massacre of 4,000–5,000 Soviet Jews the entire Ukrainian auxiliary police force actively participated.[61] In the first days of January 1942 in Kharkiv, 12,000 Jews were murdered, but smaller massacres continued in this period on daily basis in countless other locations.[60] In August 1942 in the presence of only a few German SS men over 5,000 Jews were massacred in Polish Zofjówka by the Ukrainian Auxiliary Police leading to the town's complete sweep from existence.[62]
Klempner, Mark (2017). "Heart Has Reasons: Holocaust Rescuers and Their Stories of Courage" (Website portal of resources for the book and lectures of the same name, with PDF and audio excerpts). The site includes extensive lists of articles, books and film/video/DVDs about Holocaust rescuers and related heroes, plus a reading group guide and book excerpts such as:
Jews were forced to move, often to different cities or countries, and live in designated areas, referred to as ghettos. Most of the ghettos were “open” which meant Jews were free to come and go during the daytime. As time past, more and more ghettos became “closed” meaning that Jews were trapped and not allowed to leave. No ghettos were ever established within the borders of Germany and most were only meant as a temporary means of isolating Jews from the German population until they could be moved elsewhere.
If there was a caesura towards the implementation of the Final Solution through mass murder, it is marked by the German "war of destruction" waged against the Soviet Union from June 22, 1941. Provided with instructions that called for the rapid pacification of conquered areas and that stressed the "sub-human" nature of broad strata of the population as well as the need for drastic measures to fight the deadly threat posed by "Judeo-Bolshevism" to the Nazi grand design, German soldiers, SS-men, and policemen murdered Jews from the first days of the campaign. Regionally different patterns of persecution unfolded until the end of 1941; its most prominent feature – the broadening scope of the killings from male Jews of military age (Heydrich's notorious letter to the higher SS- and Police heads in the occupied Soviet Union dated July 2, 1941, listed "Jews in party and state positions" and "other radical elements" among those to be executed) to women and children – underscores the absence of a central order and the preference of the Berlin authorities for controlled escalation.
Wounded while on campaign, Mengele returned to Germany in January 1943. He began work at the Kaiser Wilhelm Institute (KWI) for Anthropology, Human Genetics, and Eugenics, directed by his former mentor von Verschuer. In April of 1943, he received a promotion to the rank of SS captain. This promotion shortly preceded Mengele's transfer to Auschwitz, on May 30, 1943.
