Many of the horrors associated with Auschwitz—gas chambers, medical experiments, working prisoners to death—had been pioneered in earlier concentration camps. In the late thirties, driven largely by Himmler’s ambition to make the S.S. an independent economic and military power within the state, the K.L. began a transformation from a site of punishment to a site of production. The two missions were connected: the “work-shy” and other unproductive elements were seen as “useless mouths,” and forced labor was a way of making them contribute to the community. Oswald Pohl, the S.S. bureaucrat in charge of economic affairs, had gained control of the camps by 1938, and began a series of grandiose building projects. The most ambitious was the construction of a brick factory near Sachsenhausen, which was intended to produce a hundred and fifty million bricks a year, using cutting-edge equipment and camp labor.
Hitler's conception of the Aryan Herrenvolk ("Aryan master race") excluded the vast majority of Slavs from central and eastern Europe (i.e. Poles, Russians, Ukrainians, etc.). They were regarded as a race of men not inclined to a higher form of civilization, which was under an instinctive force that reverted them back to nature. The Nazis also regarded the Slavs as having dangerous Jewish and Asiatic, meaning Mongol, influences.[158] Because of this, the Nazis declared Slavs to be Untermenschen ("subhumans").[159] Nazi anthropologists attempted to scientifically prove the historical admixture of the Slavs who lived further East and leading Nazi racial theorist Hans Günther regarded the Slavs as being primarily Nordic centuries ago but he believed that they had mixed with non-Nordic types over time.[160] Exceptions were made for a small percentage of Slavs who the Nazis saw as descended from German settlers and therefore fit to be Germanised and considered part of the Aryan master race.[161] Hitler described Slavs as "a mass of born slaves who feel the need for a master".[162] The Nazi notion of Slavs as inferior served as a legitimization of their desire to create Lebensraum for Germans and other Germanic people in eastern Europe, where millions of Germans and other Germanic settlers would be moved into once those territories were conquered, while the original Slavic inhabitants were to be annihilated, removed or enslaved.[163] Nazi Germany's policy changed towards Slavs in response to military manpower shortages, forced it to allow Slavs to serve in its armed forces within the occupied territories in spite of the fact that they were considered "subhuman".[164]
Despite this process of universalization, Anne and her diary have been attacked with increasing sharpness by Holocaust deniers, and the controversy they began had additional ramifications for the diary and Anne’s character and nationality. At the end of the 1950s, after the diary was translated into English and the play earned rave reviews, the extreme right wing in Germany attacked its authenticity because, in their opinion, it was causing ever greater harm to Germany’s image. The rising controversy also included the question of the education of youth: was one who denied the diary’s authenticity fit to be a teacher? In the mid-1970s, the controversy crossed Germany’s borders, starting a trend in which there was a clear connection between Holocaust denial in general and denying the diary’s authenticity in particular, as in the statements and writings of significant Holocaust deniers such as Richard Verall and David Irving of Britain and Arthur Butz of the United States. Toward the end of the 1970s four trials began in Germany, in some of which the French Holocaust denier Robert Faurisson, together with Siegfried Verbeke of Belgium, tried hard to undermine the authenticity of the diary and support the extreme right. Otto Frank took them to court once more, as he had done in the 1950s.

In most of the camps discovered by the Soviets, almost all the prisoners had already been removed, leaving only a few thousand alive—7,000 inmates were found in Auschwitz, including 180 children who had been experimented on by doctors.[45] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division,[46] 13,000 corpses lay unburied, and another 10,000 died from typhus or malnutrition over the following weeks.[47] The British forced the remaining SS guards to gather up the corpses and place them in mass graves.[48]

The 1930 elections changed the German political landscape by weakening the traditional nationalist parties, the DNVP and the DVP, leaving the Nazis as the chief alternative to the discredited Social Democrats and the Zentrum, whose leader, Heinrich Brüning, headed a weak minority government. The inability of the democratic parties to form a united front, the self-imposed isolation of the Communists and the continued decline of the economy, all played into Hitler's hands. He now came to be seen as de facto leader of the opposition and donations poured into the Nazi Party's coffers. Some major business figures, such as Fritz Thyssen, were Nazi supporters and gave generously[71] and some Wall Street figures were allegedly involved,[72] but many other businessmen were suspicious of the extreme nationalist tendencies of the Nazis and preferred to support the traditional conservative parties instead.[73]
The pictures only came to light 25 years ago and, despite them showing moments from around 45 years before that, they completely captured the entire experience as it had been in my mind all that time. I was dumbfounded and devastated, having had no idea they existed, and I have spent literally hundreds of hours scouring them, trying to find my father and brother. The pictures have reassured me that I was not imagining it all, as I sometimes thought I might have done.
As the Russians closed in on Auschwitz, the Germans became desperate, destroying as much evidence of war crimes as they could, including records and property seized from prisoners, and forcing as many prisoners as they could on what became death marches. The day before the Russian Army liberated Auschwitz, Edith died there. On January 27 Otto was liberated and taken to Odessa and then France before being allowed to return to Amsterdam in June 1945.

Born in Frankfurt, Germany, she lived most of her life in or near Amsterdam, Netherlands, having moved there with her family at the age of four and a half when the Nazis gained control over Germany. Born a German national, she lost her citizenship in 1941 and thus became stateless. By May 1940, the Franks were trapped in Amsterdam by the German occupation of the Netherlands. As persecutions of the Jewish population increased in July 1942, the Franks went into hiding in some concealed rooms behind a bookcase in the building where Anne's father, Otto Frank, worked. From then until the family's arrest by the Gestapo in August 1944, she kept a diary she had received as a birthday present, and wrote in it regularly. Following their arrest, the Franks were transported to concentration camps. In October or November 1944, Anne and her sister, Margot, were transferred from Auschwitz to Bergen-Belsen concentration camp, where they died (probably of typhus) a few months later. They were originally estimated by the Red Cross to have died in March, with Dutch authorities setting 31 March as their official date of death, but research by the Anne Frank House in 2015 suggests they more likely died in February.[3]
On 22 June 1941, contravening the Molotov–Ribbentrop Pact, 5.5 million Axis troops attacked the Soviet Union. In addition to Hitler's stated purpose of acquiring Lebensraum, this large-scale offensive—codenamed Operation Barbarossa—was intended to destroy the Soviet Union and seize its natural resources for subsequent aggression against the Western powers.[115] The reaction among Germans was one of surprise and trepidation as many were concerned about how much longer the war would continue or suspected that Germany could not win a war fought on two fronts.[116]
Our British liberators were amazing – they were heroes for me in the real sense of the word. After their long battle to reach Belsen, they had a campaign to organise a rescue mission. To this day I’m aghast that they were so saintly. They brought little ambulances in and drove around picking us up. I was trembling and virtually lifeless, lying near the barracks, the stench of corpses everywhere, and unable to walk or lift myself up, when they arrived with a little ambulance. I don’t think I was able to talk to the soldier who approached me, my comprehension had long gone, but I remember the gentleness in him. We couldn’t eat and I remember fainting when I tried to get out of bed. Gradually they administered the food, but I didn’t trust anyone and I hid the food in my bed, afraid that they would suddenly take it away. Even now I feel that sense at every meal time of how lucky I am, and I often say to those at the table: “Isn’t this wonderful?” and “ Aren’t we lucky?”

Some of the conquered territories were incorporated into Germany as part of Hitler's long-term goal of creating a Greater Germanic Reich. Several areas, such as Alsace-Lorraine, were placed under the authority of an adjacent Gau (regional district). The Reichskommissariate (Reich Commissariats), quasi-colonial regimes, were established in some occupied countries. Areas placed under German administration included the Protectorate of Bohemia and Moravia, Reichskommissariat Ostland (encompassing the Baltic states and Belarus), and Reichskommissariat Ukraine. Conquered areas of Belgium and France were placed under control of the Military Administration in Belgium and Northern France.[167] Belgian Eupen-Malmedy, which had been part of Germany until 1919, was annexed. Part of Poland was incorporated into the Reich, and the General Government was established in occupied central Poland.[168] The governments of Denmark, Norway (Reichskommissariat Norwegen), and the Netherlands (Reichskommissariat Niederlande) were placed under civilian administrations staffed largely by natives.[167][g] Hitler intended to eventually incorporate many of these areas into the Reich.[169] Germany occupied the Italian protectorate of Albania and the Italian governorate of Montenegro in 1943[170] and installed a puppet government in occupied Serbia in 1941.[171]

It is a moral stance with specific curatorial challenges. It means restoring the crumbling brick barracks where Jews and some others were interned without rebuilding those barracks, lest they take on the appearance of a historical replica. It means reinforcing the moss-covered pile of rubble that is the gas chamber at Birkenau, the extermination camp a few miles away, a structure that the Nazis blew up in their retreat. It means protecting that rubble from water seeping in from the adjacent ponds where the ashes of the dead were dumped.
Action T4 was a programme of systematic murder of the physically and mentally handicapped and patients in psychiatric hospitals that took place mainly from 1939 to 1941, and continued until the end of the war. Initially the victims were shot by the Einsatzgruppen and others; gas chambers and gas vans using carbon monoxide were used by early 1940.[312][313] Under the Law for the Prevention of Hereditarily Diseased Offspring, enacted on 14 July 1933, over 400,000 individuals underwent compulsory sterilisation.[314] Over half were those considered mentally deficient, which included not only people who scored poorly on intelligence tests, but those who deviated from expected standards of behaviour regarding thrift, sexual behaviour, and cleanliness. Most of the victims came from disadvantaged groups such as prostitutes, the poor, the homeless, and criminals.[315] Other groups persecuted and killed included Jehovah's Witnesses, homosexuals, social misfits, and members of the political and religious opposition.[186][316]
The reality of where we were, struck home fairly quickly. I was stationed near crematorium number four, and we witnessed the columns of unsuspecting women and children entering the gate of the crematorium; they would have been dead within half an hour. When the Hungarian Jews arrived they had the gas chambers going day and night. How can you wrap your imagination round that? I still can’t.
Today, he is chairman of the International Auschwitz Council. Nothing, he says, can replace the actual site as a monument and memorial. “It’s great that you can go to a Holocaust Museum in Washington, D.C.,” he says. “But no one died in Washington in the Holocaust. Here—here is a massive cemetery without gravestones. Here they spent their last moments, here they took their last steps, here they said their last prayers, here they said goodbye to their children. Here. This is the symbol of the Holocaust.”
Medical experiments, many of them pseudoscientific, were performed on concentration camp inmates beginning in 1941.[395] The most notorious doctor to perform medical experiments was SS-Hauptsturmführer Dr. Josef Mengele, camp doctor at Auschwitz.[396] Many of his victims died or were intentionally killed.[397] Concentration camp inmates were made available for purchase by pharmaceutical companies for drug testing and other experiments.[398]
Those who reported for treatment in the infirmary had to line up in front of the infirmary barracks. After a prolonged waiting—often after hours—a doctor appeared and asked about the complaints. Thereupon he divided the prisoners into two categories: category one was examined and received into the sickroom if the occasion warranted it. In very grave cases—supposedly very rarely—inmates were taken to the police infirmary in Berlin. Category two was lined up without any sort of examination in front of the barracks, sometimes for hours, as a punishment, and then sent back to the barracks with the usual reprimands. The chief physician of the camp was called 'Dr. Cruel' by the old inmates. (His real name was Irrsam. 'Cruel' in German is grausam; the puns therefore, is not translatable.)
Lunch was three quarters of a liter of watery soup at midday, reportedly foul-tasting, with meat in the soup four times a week and vegetables (mostly potatoes and rutabaga) three times. The evening meal was 300 grams of bread, often moldy, part of which the inmates were expected to keep for breakfast the next day, with a tablespoon of cheese or marmalade, or 25 grams of margarine or sausage. Prisoners engaged in hard labor were given extra rations.[114]
Towards the war's end, in an effort to remove all traces of the crimes they had committed, the SS began to dismantle and raze the gas chambers, crematoria, and other buildings, as well as burning documents. Prisoners capable of moving were forced into death marches to other remaining areas of the Third Reich. Those who remained behind in the camp were liberated by Red Army soldiers on 27 January 1945. An estimated 1.3 million Jews, Poles, Soviet POWs, Roma, homosexuals, and Jehovah's Witnesses had been murdered within the camps by the time of liberation.
Hitler denounced the Old Testament as "Satan's Bible" and utilising components of the New Testament he attempted to prove that Jesus was both an Aryan and an antisemite by citing passages such as John 8:44 where he noted that Jesus is yelling at "the Jews", as well as saying to them "your father is the devil" and the Cleansing of the Temple, which describes Jesus' whipping of the "Children of the Devil".[209] Hitler claimed that the New Testament included distortions by Paul the Apostle, who Hitler described as a "mass-murderer turned saint".[209] In their propaganda, the Nazis utilised the writings of Martin Luther, the Protestant Reformer. They publicly displayed an original edition of Luther's On the Jews and their Lies during the annual Nuremberg rallies.[210][211] The Nazis endorsed the pro-Nazi Protestant German Christians organization.

Nazism subscribed to theories of racial hierarchy and Social Darwinism, identifying the Germans as a part of what the Nazis regarded as an Aryan or Nordic master race.[3] It aimed to overcome social divisions and create a German homogeneous society based on racial purity which represented a people's community (Volksgemeinschaft). The Nazis aimed to unite all Germans living in historically German territory, as well as gain additional lands for German expansion under the doctrine of Lebensraum and exclude those who they deemed either community aliens or "inferior" races.
Between 1933 and the fall of Nazi Germany in 1945, more than 3.5 million Germans were forced to spend time in concentration camps and prisons for political reasons,[18][19][20] and approximately 77,000 Germans were executed for one or another form of resistance by Special Courts, courts-martial, and the civil justice system. Many of these Germans had served in government, the military, or in civil positions, which enabled them to engage in subversion and conspiracy against the Nazis.[11]
