After the Night of the Long Knives, Hitler promoted Himmler and the SS, who then zealously suppressed homosexuality by saying: "We must exterminate these people root and branch ... the homosexual must be eliminated".[201] In 1936, Himmler established the "Reichszentrale zur Bekämpfung der Homosexualität und Abtreibung" ("Reich Central Office for the Combating of Homosexuality and Abortion").[202] The Nazi regime incarcerated some 100,000 homosexuals during the 1930s.[203] As concentration camp prisoners, homosexual men were forced to wear pink triangle badges.[204][205] Nazi ideology still viewed German men who were gay as a part of the Aryan master race, but the Nazi regime attempted to force them into sexual and social conformity. Homosexuals were viewed as failing in their duty to procreate and reproduce for the Aryan nation. Gay men who would not change or feign a change in their sexual orientation were sent to concentration camps under the "Extermination Through Work" campaign.[206]
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.
In the decades since its liberation, Auschwitz has become a primary symbol of the Holocaust. Historian Timothy D. Snyder attributes this to the camp's high death toll and "unusual combination of an industrial camp complex and a killing facility", which left behind far more witnesses than single-purpose killing facilities such as Chełmno or Treblinka.[272] In 2005 the United Nations General Assembly designated 27 January, the date of the camp's liberation, as International Holocaust Remembrance Day.[273] Helmut Schmidt visited the site in November 1977, the first West German chancellor to do so, followed by his successor, Helmut Kohl, in November 1989.[274] In a written statement on the fiftieth anniversary of the liberation, Kohl described Auschwitz as the "darkest and most horrific chapter of German history".[275]
We had no daily paper, no radio or phone, so the only news we got of the second world war was from newcomers to town. The change started at the end of 1942-43, when people began expressing their anger towards us, especially the Hungarian neighbours. We’d hear: “Zsidók, menjetek ki, Gyerünk haza!” (“Jews, get out of here, Go home!”) I was in the synagogue singing when a rock shattered the stained-glass window. The rabbi tried to convince us it was just some drunk, but as a 10-year-old, I knew better.
The Zyklon B was delivered by ambulance to the crematoria by a special SS bureau known as the Hygienic Institute.[104] The actual delivery of the gas to the victims was always handled by the SS, on the order of the supervising SS doctor.[174][175] After the doors were shut, SS men dumped in the Zyklon B pellets through vents in the roof or holes in the side of the chamber. The victims were dead within 20 minutes.[174] Despite the thick concrete walls, screaming and moaning from within could be heard outside. In one failed attempt to muffle the noise, two motorcycle engines were revved up to full throttle nearby, but the sound of yelling could still be heard over the engines.[176]

The process of Anne’s transformation into a universal teenager continued with the Americanization of her diary. “These are the thoughts and expression of a young girl living under extraordinary conditions, and for this reason her diary tell us much about ourselves and about our own children. And for this reason, too, I felt how close we all are to Anne’s experience, how very much involved we are in her short life and in the entire world,” Eleanor Roosevelt wrote in her introduction. Were Americans living in 1952 really close to Anne’s experiences? Were they really capable of understanding her and becoming involved in her life? Perhaps they were, though not as a Jewish girl hiding from the Nazis, but as an “Everygirl.” In her foreword, Eleanor Roosevelt makes no reference to Jews or to Anne’s Jewishness, nor to the way her brief life ended, nor to the Holocaust, thus distancing the diary even more from Jews and from the Holocaust by referring to human problems in general.
Victor Kugler and Johannes Kleiman were arrested and jailed at the penal camp for enemies of the regime at Amersfoort. Kleiman was released after seven weeks, but Kugler was held in various work camps until the war's end.[39] Miep Gies and Bep Voskuijl were questioned and threatened by the Security Police but not detained. They returned to the Achterhuis the following day, and found Anne's papers strewn on the floor. They collected them, as well as several family photograph albums, and Gies resolved to return them to Anne after the war. On 7 August 1944, Gies attempted to facilitate the release of the prisoners by confronting Silberbauer and offering him money to intervene, but he refused.[40]
Popular support for Hitler almost completely disappeared as the war drew to a close.[145] Suicide rates in Germany increased, particularly in areas where the Red Army was advancing. Among soldiers and party personnel, suicide was often deemed an honourable and heroic alternative to surrender. First-hand accounts and propaganda about the uncivilised behaviour of the advancing Soviet troops caused panic among civilians on the Eastern Front, especially women, who feared being raped.[146] More than a thousand people (out of a population of around 16,000) committed suicide in Demmin on and around 1 May 1945 as the 65th Army of 2nd Belorussian Front first broke into a distillery and then rampaged through the town, committing mass rapes, arbitrarily executing civilians, and setting fire to buildings. High numbers of suicides took place in many other locations, including Neubrandenburg (600 dead), Stolp in Pommern (1,000 dead),[147] and Berlin, where at least 7,057 people committed suicide in 1945.[148]

Very heavy strategic bombing by the Allies targeted refineries producing synthetic oil and gasoline, as well as the German transportation system, especially rail yards and canals.[287] The armaments industry began to break down by September 1944. By November, fuel coal was no longer reaching its destinations and the production of new armaments was no longer possible.[288] Overy argues that the bombing strained the German war economy and forced it to divert up to one-fourth of its manpower and industry into anti-aircraft resources, which very likely shortened the war.[289]
The train wasn’t headed to Germany. Stos was on the first transport of Polish prisoners to Auschwitz. There to greet them were 30 hardened German convicts, brought by the SS from a prison near Berlin. Guards confiscated Stos’ belongings and issued him a number. Sixty-nine years later, he slid a business card across the dining room table as his daughter brought us cups of tea. It read “Jozef Stos, former Auschwitz Concentration Camp Prisoner No. 752.” “I was there on the first day,” he said. “They had me for five years and five days.”
What would it mean for a writer not to hide the horror? There is no mystery here, only a lack of interest. To understand what we are missing, consider the work of another young murdered Jewish chronicler of the same moment, Zalmen Gradowski. Like Frank’s, Gradowski’s work was written under duress and discovered only after his death—except that Gradowski’s work was written in Auschwitz, and you have probably never heard of it.

The first prisoners at Auschwitz included German prisoners transferred from Sachsenhausen concentration camp in Germany, where they had been incarcerated as repeat criminal offenders, and Polish political prisoners from Lodz via Dachau concentration camp and from Tarnow in Krakow District of the Generalgouvernement (that part of German-occupied Poland not annexed to Nazi Germany, linked administratively to German East Prussia, or incorporated into the German-occupied Soviet Union).

An elaborate bureaucracy was created to regulate imports of raw materials and finished goods with the intention of eliminating foreign competition in the German marketplace and improving the nation's balance of payments. The Nazis encouraged the development of synthetic replacements for materials such as oil and textiles.[255] As the market was experiencing a glut and prices for petroleum were low, in 1933 the Nazi government made a profit-sharing agreement with IG Farben, guaranteeing them a 5 percent return on capital invested in their synthetic oil plant at Leuna. Any profits in excess of that amount would be turned over to the Reich. By 1936, Farben regretted making the deal, as excess profits were by then being generated.[256] In another attempt to secure an adequate wartime supply of petroleum, Germany intimidated Romania into signing a trade agreement in March 1939.[257]
Some Auschwitz prisoners were subjected to inhumane medical experimentation. The chief perpetrator of this barbaric research was Josef Mengele (1911-79), a German physician who began working at Auschwitz in 1943. Mengele, who came to be known as the “Angel of Death,” performed a range of experiments on detainees. For example, in an effort to study eye color, he injected serum into the eyeballs of dozens of children, causing them excruciating pain. He also injected chloroform into the hearts of twins, to determine if both siblings would die at the same time and in the same manner.
National Socialism (German: Nationalsozialismus), more commonly known as Nazism (/ˈnɑːtsiɪzəm, ˈnæt-/),[1] is the ideology and practices associated with the Nazi Party – officially the National Socialist German Workers' Party (Nationalsozialistische Deutsche Arbeiterpartei or NSDAP) – in Nazi Germany, and of other far-right groups with similar aims.
Ms. Jastrzebiowska’s husband, Andrzej Jastrzebiowski, 38, is a metal conservator. He spent three months cleaning all the eyeglasses in a vitrine, preserving their distressed state but trying to prevent them from corroding further. “When I saw the eyeglasses in the exhibition, I saw it as one big pile,” he said. But in the lab, he began to examine them one by one. One had a screw replaced by a bent needle; another had a repaired temple. “And then this enormous mass of glasses started becoming people,” Mr. Jastrzebiowski said. This “search for the individual,” he said, helps ensure that the work does not become too routine.
On August 4, 1944, the police discovered the secret annex after receiving an anonymous tip. The group in the annex were taken completely by surprise—the SS officer and the four Dutch Nazis who conducted the raid proceeded quickly, drawing guns to keep the employees from warning those in hiding and forcing Kugler to reveal the entrance to the annex, which was concealed by a movable bookcase. Everyone in the annex was taken into custody along with Kleiman and Kugler, who were imprisoned for helping to conceal the group. The Franks, the van Pels, and Pfeffer were taken to a police station in Amsterdam and four days later, taken to the Westerbork transit camp. On September 3 they were transported in a sealed cattle car to Auschwitz in Poland—the last transport to ever leave Westerbork. Three days later, Hermann van Pels was gassed at Auschwitz.
Hitler had the final say in both domestic legislation and German foreign policy. Nazi foreign policy was guided by the racist belief that Germany was biologically destined to expand eastward by military force and that an enlarged, racially superior German population should establish permanent rule in eastern Europe and the Soviet Union. Here, women played a vital role. The Third Reich's aggressive population policy encouraged "racially pure" women to bear as many "Aryan" children as possible.
The only people left behind in the camp were people deemed unfit for labor—those who were too ill or weak. An SS order came down to murder any prisoners who were left, and the SS killed about 700 prisoners in response. However, order at the camp was breaking down. SS officers began escaping themselves, and the strict hierarchy that had kept prisoners in line disappeared. Those officers who stayedburned documents in a last-ditch attempt to hide their crimes. Meanwhile, the prisoners who remained huddled in hospital beds and bunks and waited. A few others escaped as the remaining guards fled.
The conference led to a dramatic increase in activity at the Nazi death camps. In a massive campaign code-named Operation Reinhard, Germans killed 1.5 million Jews at small camps deep in the forests of eastern Poland from March 1942 to October 1943. Treblinka and the now nearly forgotten camps Sobibor and Belzec consisted of little more than gas chambers and train tracks. There were virtually no survivors, no witnesses.
In Autumn 1943, the camp administration was reorganized following a corruption scandal. By the end of 1943, the prisoner population of Auschwitz main camp, Birkenau, Monowitz and other subcamps was over 80,000: 18,437 in the main camp, 49,114 in Birkenau, and 13,288 at Monowitz where I G Farben had its synthetic rubber plant. Up to 50,000 prisoners were scattered around 51 subcamps such as Rajsko, an experimental agricultural station, and Gleiwitz, a coal mine (see The List of the Camps for a complete list of those subcamps).
To help carry out the "Final Solution" (the genocide or mass destruction of Jews), the Nazis established killing centers in German-occupied  Poland, the country with the largest Jewish population. Killing centers were designed for efficient mass murder. The first one, which opened in December 1941, was Chelmno, where Jews and Roma were gassed in mobile gas vans. In 1942, the Nazis opened the Belzec, Sobibor, and Treblinka killing centers to systematically murder the Jews of the Generalgouvernement (the territory in the interior of German-occupied Poland).
None of the categories are independent - one could classify many camps as a mixture of several of the above. All camps had some of the elements of an extermination camp, but systematic extermination of new arrivals by gas chambers only occurred in specialized camps. These were extermination camps, where all new-arrivals were simply killed—the "Aktion Reinhard" camps (Treblinka, Sobibór and Belzec), together with Chelmno. Two others ( Auschwitz and Majdanek) operated as combined concentration- and extermination-camps. Others like Maly Trostenets were at times classified[by whom?] as "minor extermination camps".[50]
