Wilhelm Stapel, an antisemitic German intellectual, utilised Spengler's thesis on the cultural confrontation between Jews as whom Spengler described as a Magian people versus Europeans as a Faustian people.[117] Stapel described Jews as a landless nomadic people in pursuit of an international culture whereby they can integrate into Western civilisation.[117] As such, Stapel claims that Jews have been attracted to "international" versions of socialism, pacifism or capitalism because as a landless people the Jews have transgressed various national cultural boundaries.[117]
Auschwitz-Birkenau became the killing centre where the largest numbers of European Jews were killed during the Holocaust. After an experimental gassing there in September 1941 of 850 malnourished and ill prisoners, mass murder became a daily routine. By mid 1942, mass gassing of Jews using Zyklon-B began at Auschwitz, where extermination was conducted on an industrial scale with some estimates running as high as three million persons eventually killed through gassing, starvation, disease, shooting, and burning ...
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.)

In the Soviet Union by 1922 there were 23 concentration camps for the incarceration of persons accused of political offenses as well as criminal offenses. Many corrective labour camps were established in northern Russia and Siberia, especially during the First Five-Year Plan, 1928–32, when millions of rich peasants were driven from their farms under the collectivization program. The Stalinist purges of 1936–38 brought additional millions into the camps—said to be essentially institutions of slavery.

The publication of the English-language critical/definitive edition in 1989 sparked a worldwide wave of research that focused on Anne Frank from different perspectives: the literary perspective; the diary as a historical document; the feminist angle; the diary’s Jewish aspect and its portrayal of Jewish life in central and western Europe; wartime adolescence; the adolescence of a promising writer, and more. In 1996, Jon Blair’s documentary Anne Frank Remembered won an Academy Award, and another exhibit, Anne Frank: A History for Today, prepared at the Anne Frank House went on tour. The exhibit immediately became a symbol of struggle, deprivation and suffering, discrimination against the individual and minorities, occupation and oppression. In every place it was shown, the need to educate against fascism and xenophobia, Holocaust denial and antisemitism was emphasized. The catalog stresses that “[T]he Anne Frank House tries to realize Anne’s ideals as she spoke of them in her diary by fighting prejudice, antisemitism and racism through fostering pluralistic and democratic society. The guiding principle of the House’s work is the Universal Declaration of Human Rights.” Eleanor Roosevelt, who as a member of the United States’s delegation to the United Nations had headed the committee that prepared the Declaration in the wake of World War II, wrote the foreword to the diary’s English edition shortly afterward.

After a fortnight we were able to use the money which we had brought in or was sent to us, and it became possible to complete and improve our diet from the canteen at our own expense. We were lined up in rows exactly in the order of our prison numbers, which had been sewed in black on white on our clothes. (This also is penitentiary procedure, for an inmate of the penitentiary is not an individual any more, but only a numbered being without a name.) Then we were led into the barracks where an S.S. man sitting behind a sort of teller's window disbursed the desired sum, up to fifteen marks a week. Somehow I must have transgressed against the military discipline in this procedure. I presume that I had my cap in the wrong hand. Instead of the money I received a violent blow on the back of my hand with a heavy stick which was lying next to the paymaster on his table, obviously for such purposes. Many weeks after this experience the back of my hand was still painful and swollen.
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]
On a nearby table sat the second horn part to Tchaikovsky’s Capriccio Italien (Op. 45), which had been played by the death camp’s orchestra. Ms. Jastrzebiowska would preserve the page as it was, she said, and keep the smudges showing that the pages had been turned. “The objects must show their own history,” said Jolanta Banas-Maciaszczyk, 36, the leader of the preservation department.
On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households.[12] The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship.[13] By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.[14][15]
The direct reason for the establishment of the camp was the fact that mass arrests of Poles were increasing beyond the capacity of existing "local" prisons. The first transport of Poles reached KL Auschwitz from Tarnów prison on June 14, 1940. Initially, Auschwitz was to be one more concentration camp of the type that the Nazis had been setting up since the early 1930s. It functioned in this role throughout its existence, even when, beginning in 1942, it also became the largest of the death camps.
After this we were taken to another room in which we were forced to strip. Then our heads were clipped short and all signs of beard were removed. According to an old tradition in Germany, the cropped hair is a distinguishing mark of the serf in contrast to the free man. After this procedure and a sort of 'medical examination' by another inmate employed as attendant, we received the benefit of a hot shower, which somewhat refreshed us and loosened up our limbs, stiff from the long stand in the cold.

By early 1934, the focus shifted towards rearmament. By 1935, military expenditures accounted for 73 percent of the government's purchases of goods and services.[267] On 18 October 1936, Hitler named Göring as Plenipotentiary of the Four Year Plan, intended to speed up rearmament.[268] In addition to calling for the rapid construction of steel mills, synthetic rubber plants, and other factories, Göring instituted wage and price controls and restricted the issuance of stock dividends.[251] Large expenditures were made on rearmament in spite of growing deficits.[269] Plans unveiled in late 1938 for massive increases to the navy and air force were impossible to fulfil, as Germany lacked the finances and material resources to build the planned units, as well as the necessary fuel required to keep them running.[270] With the introduction of compulsory military service in 1935, the Reichswehr, which had been limited to 100,000 by the terms of the Versailles Treaty, expanded to 750,000 on active service at the start of World War II, with a million more in the reserve.[271] By January 1939, unemployment was down to 301,800 and it dropped to only 77,500 by September.[272]
On 24 December 1941 the resistance groups representing the various prisoner factions met in block 45 and agreed to cooperate. Fleming writes that it has not been possible to track Pilecki's early intelligence from the camp. Pilecki compiled two reports after he escaped in April 1943; the second, Raport W, detailed his life in Auschwitz I and estimated that 1.5 million people, mostly Jews, had been killed.[204] On 1 July 1942, the Polish Fortnightly Review published a report describing Birkenau, writing that "prisoners call this supplementary camp 'Paradisal', presumably because there is only one road, leading to Paradise". Reporting that inmates were being killed "through excessive work, torture and medical means", it noted the gassing of the Soviet prisoners of war and Polish inmates in Auschwitz I in September 1941, the first gassing in the camp. It said: "It is estimated that the Oswiecim camp can accommodate fifteen thousand prisoners, but as they die on a mass scale there is always room for new arrivals."[205]
For the preservation staff, the burden of remembrance informs every aspect of their restoration efforts. “If there’s damage to an object as part of its history, we leave it that way,” Banas says. She points to crates of shoes stacked in a hallway, most with worn insoles and uneven heels—signs of human use that will be left as they are. The International Auschwitz Council—museum officials and survivors from around the world dedicated to the conservation of Auschwitz—has decided that the mounds of hair will be allowed to decay naturally because they are human remains.
The resistance sent out the first oral message about Auschwitz with Dr. Aleksander Wielkopolski, a Polish engineer who was released in October 1940.[202] The following month the Polish underground in Warsaw prepared a report on the basis of that information, The camp in Auschwitz, part of which was published in London in May 1941 in a booklet, The German Occupation of Poland, by the Polish Ministry of Foreign Affairs. The report said of the Jews in the camp that "scarcely any of them came out alive". According to Fleming, the booklet was "widely circulated amongst British officials". The Polish Fortnightly Review based a story on it, writing that "three crematorium furnaces were insufficient to cope with the bodies being cremated", as did The Scotsman on 8 January 1942, the only British news organization to do so.[203]
Between May 15 and July 9, 1944, some 438,000 Hungarian Jews were shipped on 147 trains to Birkenau, stretching the camp’s resources for killing beyond all limits. Because the crematoria were overcrowded, bodies were burned in pyres fueled partly by the victims’ own fat. Just prior to the deportation of Hungarian Jewry, two prisoners escaped with plans of the camp. They met with resistance leaders in Slovakia and compiled a detailed report including maps. As this report made its way to Western intelligence services in the summer of 1944, there were requests to bomb Auschwitz. Although the industrial complex adjacent to Auschwitz was bombed, the death camp and its crematoria were left untouched, a subject of controversy more than 50 years later. (See Why Wasn’t Auschwitz Bombed?)
The Auschwitz Birkenau camp complex comprises 155 brick and wooden structures (57 in Auschwitz and 98 in Birkenau) and about 300 ruins. There are also ruins of gas chambers and crematoria in Birkenau, which were dynamited in January 1945. The overall length of fencing supported by concrete poles is more than 13 km. Individual structures of high historical significance, such as railway sidings and ramps, food stores and industrial buildings, are dispersed in the immediate setting of the property. These structures, along with traces in the landscape, remain poignant testimonies to this tragic history.

After the selection process was complete, those too ill or too young to walk to the crematoria were transported there on trucks or killed on the spot with a bullet to the head.[169][170] The belongings of the arrivals were seized by the SS and sorted in an area of the camp called "Canada", so called because Canada was seen as a land of plenty. Many of the SS at the camp enriched themselves by pilfering the confiscated property.[171]

Most of the POWs died within weeks. “When it was time to get up in the morning, those who were alive moved, and around them would be two or three dead people,” one Russian survivor says in the 2005 book Auschwitz: A New History by Laurence Rees. “Death at night, death in the morning, death in the afternoon. There was death all the time.” The prisoners built the barracks at Birkenau in a rush, laying a single course of bricks on poorly made foundations. The flood of Soviet POWs overwhelmed the already crowded camp. Pressure to “eliminate” people—the Nazi euphemism—grew.
Some of the most notorious slave labour camps included a network of subcamps. Gross-Rosen had 100 subcamps,[37] Auschwitz had 44 subcamps,[38][38][39] Stutthof had 40 sub-camps set up contingently.[40] Prisoners in these subcamps were dying from starvation, untreated disease and summary executions by the tens of thousands already since the beginning of war.[41]
