Eventually, Birkenau held the majority of prisoners in the Auschwitz complex, including Jews, Poles, Germans, and Gypsies. Furthermore, it maintained the most degrading and inhumane conditions–inclusive of the complex’s gas chambers and crematoria. A third section, Auschwitz III, was constructed in nearby Monowitz, and consisted of a forced labor camp called Buna-Monowitz.

These guards were the core of what became, a few years later, the much feared Death’s-Head S.S. The name, along with the skull-and-crossbones insignia, was meant to reinforce the idea that the men who bore it were not mere prison guards but front-line soldiers in the Nazi war against enemies of the people. Himmler declared, “No other service is more devastating and strenuous for the troops than just that of guarding villains and criminals.” The ideology of combat had been part of the DNA of Nazism from its origin, as a movement of First World War veterans, through the years of street battles against Communists, which established the Party’s reputation for violence. Now, in the years before actual war came, the K.L. was imagined as the site of virtual combat—against Communists, criminals, dissidents, homosexuals, Jehovah’s Witnesses, and Jews, all forces working to undermine the German nation.
Subject to harsh conditions—including inadequate shelter and sanitation—given minimal food, and worked to exhaustion, those who could no longer work faced transport back to Birkenau for gassing. German corporations invested heavily in the slave-labour industries adjacent to Auschwitz. In 1942 IG Farben alone invested more than 700 million Reichsmarks in its facilities at Auschwitz III.
Soon afterwards, the gas chambers and crematoria were destroyed on Himmler's orders, since the regime wanted to hide the traces of its murdering machine ahead of the advancing Red Army. As Soviet troops came near to the camp in January 1945, it was hurriedly evacuated and 58 000 prisoners were driven out on a death march, during which most were killed. On the 27th of January 1945, the Red Army entered the camp (link in Czech). They found 7 650 exhausted and starving prisoners and a number of pieces of evidence of crimes that the Nazis had not had time to destroy. In the camp stores they found almost eight tonnes of human hair and over a million men's suits and women's dresses.

At the end of the war, Europe had more than 40 million refugees,[156] its economy had collapsed, and 70 percent of its industrial infrastructure was destroyed.[157] Between twelve and fourteen million ethnic Germans fled or were expelled from central, eastern, and southeastern Europe to Germany.[158] The West German government estimated a death toll of 2.2 million civilians due to the flight and expulsion of Germans and through forced labour in the Soviet Union.[159] This figure remained unchallenged until the 1990s, when some historians put the death toll at 500,000–600,000 confirmed deaths.[160][161][162] In 2006, the German government reaffirmed its position that 2.0–2.5 million deaths occurred.[f]

German doctors performed a variety of experiments on prisoners at Auschwitz. SS doctors tested the efficacy of X-rays as a sterilization device by administering large doses to female prisoners. Carl Clauberg injected chemicals into women's uteruses in an effort to glue them shut. Prisoners were infected with spotted fever for vaccination research and exposed to toxic substances to study the effects.[125] In one experiment Bayer, then part of IG Farben, paid RM 150 each for 150 female inmates from Auschwitz (the camp had asked for RM 200 per woman), who were transferred to a Bayer facility to test an anesthetic. A Bayer employee wrote to Rudolf Höss: "The transport of 150 women arrived in good condition. However, we were unable to obtain conclusive results because they died during the experiments. We would kindly request that you send us another group of women to the same number and at the same price." The Bayer research was led at Auschwitz by Helmuth Vetter of Bayer/IG Farben, who was also an Auschwitz physician and SS captain, and by Auschwitz physicians Friedrich Entress and Eduard Wirths.[126]
Various other German industrial enterprises, such as Krupp and Siemens-Schuckert, built factories with their own subcamps.[68] There were around 40[69] or 50[70] such camps, 28 of them near industrial plants, each camp holding hundreds or thousands of prisoners.[71] Designated as Aussenlager (external camp), Nebenlager (extension or subcamp), or Arbeitslager (labor camp),[69] camps were built at Blechhammer, Jawiszowice, Jaworzno, Lagisze, Mysłowice, Trzebinia, and centers as far afield as the Protectorate of Bohemia and Moravia in Czechoslovakia.[72][73][74] Industries with satellite camps included coal mines, foundries and other metal works, and chemical plants. Prisoners were also made to work in forestry and farming.[75] Budy, for example, was a farming subcamp where prisoners worked 12-hour days, often in the fields, but sometimes tending animals, cleaning ponds, digging ditches, and making compost. Human ashes from the crematorium were mixed with sod and manure to make the compost.[76] Incidents of sabotage to decrease production took place in several subcamps, including Charlottengrube, Gleiwitz II, and Rajsko.[77]
The Auschwitz complex was divided in three major camps: Auschwitz I main camp or Stammlager; Auschwitz II, or Birkenau, established on October 8th, 1941 as a 'Vernichtungslager' (extermination camp); Auschwitz III or Monowitz, established on May 31th, 1942 as an 'Arbeitslager' or work camp; also several sub-camps. There were up to seven gas chambers using Zyklon-B poison gas and three crematoria. Auschwitz II included a camp for new arrivals and those to be sent on to labor elsewhere; a Gypsy camp; a family camp; a camp for holding and sorting plundered goods and a women's camp. Auschwitz III provided slave labor for a major industrial plant run by I G Farben for producing synthetic rubber (see Blechhammer). Highest number of inmates, including sub-camps: 155,000. The estimated number of deaths: 2.1 to 2.5 million killed in gas chambers, of whom about 2 million were Jews, and Poles, Gypsies and Soviet POWs. About 330,000 deaths from other causes.
Primary and secondary education focused on racial biology, population policy, culture, geography, and physical fitness.[357] The curriculum in most subjects, including biology, geography, and even arithmetic, was altered to change the focus to race.[358] Military education became the central component of physical education, and education in physics was oriented toward subjects with military applications, such as ballistics and aerodynamics.[359][360] Students were required to watch all films prepared by the school division of the Reich Ministry of Public Enlightenment and Propaganda.[355]
Carl Clauberg was put to trial in the Soviet Union and sentenced to 25 years. 7 years later, he was pardonned under the returnee arrangement between Bonn and Moscow and went back to West Germany. Upon returning he held a press conference and boasted of his scientific work at Auschwitz. After survivor groups protested, Clauberg was finally arrested in 1955 but died in August 1957, shortly before his trial should have started.
In 2016, the Anne Frank House published new research pointing to investigation over ration card fraud, rather than betrayal, as a plausible explanation for the raid that led to the arrest of the Franks.[46] The report states that other activities in the building may have led authorities there, including activities of Frank's company. However, it does not rule out betrayal.[47]

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]

German authorities established camps all over Germany on an ad hoc basis to handle the masses of people arrested as alleged subversives. The SS established larger camps in Oranienburg, north of Berlin; Esterwegen, near Hamburg; Dachau, northwest of Munich; and Lichtenburg, in Saxony. In Berlin itself, the Columbia Haus facility held prisoners under investigation by the Gestapo (the German secret state police) until 1936.
In May 1940, Germany invaded the Netherlands, and the occupation government began to persecute Jews by the implementation of restrictive and discriminatory laws; mandatory registration and segregation soon followed.[13] Otto Frank tried to arrange for the family to emigrate to the United States – the only destination that seemed to him to be viable[14] – but Frank's application for a visa was never processed, due to circumstances such as the closing of the U.S. consulate in Rotterdam and the loss of all the paperwork there, including the visa application.[15] Even if it had been processed, the U.S. government at the time was concerned that people with close relatives still in Germany could be blackmailed into becoming Nazi spies.[14]
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]
The new Jewish pavilion opened in 2013. It was designed by Yad Vashem, the Holocaust memorial in Jerusalem. It shows black-and-white films of Jewish life in Europe before the war, then of Hitler’s rallies. In one room, the Israeli artist Michal Rovner has copied children’s drawings from the camp onto the wall. In another, names of some of the six million Holocaust dead are printed on a long row of pages, their edges yellowing from human touch.
The camps were liberated by the Allied forces between 1944 and 1945. The first major camp, Majdanek, was discovered by the advancing Soviets on July 23, 1944. Auschwitz was liberated, also by the Soviets, on January 27, 1945; Buchenwald by the Americans on April 11; Bergen-Belsen by the British on April 15; Dachau by the Americans on April 29; Ravensbrück by the Soviets on the same day; Mauthausen by the Americans on May 5; and Theresienstadt by the Soviets on May 8.[42] Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Nazis in 1943. Colonel William W. Quinn of the U.S. 7th Army said of Dachau: "There our troops found sights, sounds, and stenches horrible beyond belief, cruelties so enormous as to be incomprehensible to the normal mind."[43][44]
