Construction of crematorium I began at Auschwitz I at the end of June or beginning of July 1940.[26] Initially intended not for mass murder but for prisoners who had been executed or had otherwise died in the camps, the crematorium was in operation from August 1940 until July 1943, by which time the crematoria at Auschwitz II had taken over.[27] By May 1942 three ovens had been installed in crematorium I, which together could burn 340 bodies in 24 hours.[28]
In 2017 a Körber Foundation survey found that 40 percent of 14-year-olds in Germany did not know what Auschwitz was.[281][282] The following year a survey organized by the Claims Conference, United States Holocaust Memorial Museum and others found that 41 percent of 1,350 American adults surveyed, and 66 percent of millennials, did not know what Auschwitz was, while 22 percent said they had never heard of the Holocaust.[283] A CNN-ComRes poll in 2018 found a similar situation in Europe.[284]

The first camp in Germany, Dachau, was founded in March 1933.[13] The press announcement said that "the first concentration camp is to be opened in Dachau with an accommodation for 5,000 people. All Communists and – where necessary – Reichsbanner and Social Democratic functionaries who endanger state security are to be concentrated there, as in the long run it is not possible to keep individual functionaries in the state prisons without overburdening these prisons."[13] Dachau was the first regular concentration camp established by the German coalition government of National Socialist Workers' Party (Nazi Party) and the Nationalist People's Party (dissolved on 6 July 1933). Heinrich Himmler, then Chief of Police of Munich, officially described the camp as "the first concentration camp for political prisoners."[13]
The 24th edition of Etymologisches Wörterbuch der deutschen Sprache (2002) says the word Nazi was favored in southern Germany (supposedly from c.1924) among opponents of National Socialism because the nickname Nazi, Naczi (from the masc. proper name Ignatz, German form of Ignatius) was used colloquially to mean "a foolish person, clumsy or awkward person." Ignatz was a popular name in Catholic Austria, and according to one source in World War I Nazi was a generic name in the German Empire for the soldiers of Austria-Hungary.
During the Röhm Purge of 30 June to 2 July 1934 (also known as the "Night of the Long Knives"), Hitler disempowered the SA's leadership—most of whom belonged to the Strasserist (national revolutionary) faction within the NSDAP—and ordered them killed. He accused them of having conspired to stage a coup d'état, but it is believed that this was only a pretence to justify the suppression of any intraparty opposition. The purge was executed by the SS, assisted by the Gestapo and Reichswehr units. Aside from Strasserist Nazis, they also murdered anti-Nazi conservative figures like former chancellor Kurt von Schleicher.[84] After this, the SA continued to exist but lost much of its importance, while the role of the SS grew significantly. Formerly only a sub-organisation of the SA, it was made into a separate organisation of the NSDAP in July 1934.[85]
On 1 September 1939, when Anne was 10 years old, Nazi Germany invaded Poland, and so the Second World War began. Not long after, on 10 May 1940, the Nazis also invaded the Netherlands. Five days later, the Dutch army surrendered. Slowly but surely, the Nazis introduced more and more laws and regulations that made the lives of Jews more difficult. For instance, Jews could no longer visit parks, cinemas, or non-Jewish shops. The rules meant that more and more places became off-limits to Anne. Her father lost his company, since Jews were no longer allowed to run their own businesses. All Jewish children, including Anne, had to go to separate Jewish schools.
Tens of thousands of prisoners, mostly Jews, were forced to march either northwest for 55 kilometers (approximately 30 miles) to Gliwice (Gleiwitz) or due west for 63 kilometers (approximately 35 miles) to Wodzislaw (Loslau) in the western part of Upper Silesia. Those forced to march northwest were joined by prisoners from subcamps in East Upper Silesia, such as Bismarckhuette, Althammer, and Hindenburg. Those forced to march due west were joined by inmates from the subcamps to the south of Auschwitz, such as Jawischowitz, Tschechowitz, and Golleschau.

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]

In the spring of 1941, the SS—along with doctors and officials of the T-4 Euthanasia Program—introduced the Action 14f13 programme meant for extermination of selected concentration camp prisoners.[31] The Inspectorate of the Concentration Camps categorized all files dealing with the death of prisoners as 14f, and those of prisoners sent to the T-4 gas chambers as 14f13. Under the language regulations of the SS, selected prisoners were designated for "special treatment (German: Sonderbehandlung) 14f13". Prisoners were officially selected based on their medical condition; namely, those permanently unfit for labor due to illness. Unofficially, racial and eugenic criteria were used: Jews, the handicapped, and those with criminal or antisocial records were selected.[32]:p.144 For Jewish prisoners there was not even the pretense of a medical examination: the arrest record was listed as a physician's "diagnosis".[32]:pp. 147–148 In early 1943, as the need for labor increased and the gas chambers at Auschwitz became operational, Heinrich Himmler ordered the end of Action 14f13.[32]:p.150
Mendelian inheritance, or Mendelism, was supported by the Nazis, as well as by mainstream eugenicists of the time. The Mendelian theory of inheritance declared that genetic traits and attributes were passed from one generation to another.[104] Eugenicists used Mendelian inheritance theory to demonstrate the transfer of biological illness and impairments from parents to children, including mental disability, whereas others also utilised Mendelian theory to demonstrate the inheritance of social traits, with racialists claiming a racial nature behind certain general traits such as inventiveness or criminal behaviour.[105]
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]
Fleeing Germans also torched a couple of dozen of the wooden barracks at Birkenau. Many of the camp buildings that were left largely intact were later taken apart by Poles desperate for shelter. Birkenau remains the starkest, most tangible, most haunting reminder of what Dwork says was the “greatest catastrophe Western civilization permitted, and endured.”

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]

Cornelis Suijk—a former director of the Anne Frank Foundation and president of the U.S. Center for Holocaust Education Foundation—announced in 1999 that he was in the possession of five pages that had been removed by Otto Frank from the diary prior to publication; Suijk claimed that Otto Frank gave these pages to him shortly before his death in 1980. The missing diary entries contain critical remarks by Anne Frank about her parents' strained marriage and discuss Frank's lack of affection for her mother.[76] Some controversy ensued when Suijk claimed publishing rights over the five pages; he intended to sell them to raise money for his foundation. The Netherlands Institute for War Documentation, the formal owner of the manuscript, demanded the pages be handed over. In 2000 the Dutch Ministry of Education, Culture and Science agreed to donate US$300,000 to Suijk's foundation, and the pages were returned in 2001. Since then, they have been included in new editions of the diary.[77]
Hitler expressed opposition to capitalism, regarding it as having Jewish origins and accusing capitalism of holding nations ransom to the interests of a parasitic cosmopolitan rentier class.[51] He also expressed opposition to communism and egalitarian forms of socialism, arguing that inequality and hierarchy are beneficial to the nation.[52] He believed that communism was invented by the Jews to weaken nations by promoting class struggle.[53] After his rise to power, Hitler took a pragmatic position on economics, accepting private property and allowing capitalist private enterprises to exist so long as they adhered to the goals of the Nazi state, but not tolerating enterprises that he saw as being opposed to the national interest.[37]
Auschwitz-Birkenau was also a killing center and played a central role in the German effort to kill the Jews of Europe. Around the beginning of September, 1941, the SS at Auschwitz I conducted the first tests of Zyklon B as a mass murder agent, using Soviet POWs and debilitated Polish prisoners as victims. The “success” of these experiments led to the construction of a chamber in the crematorium of Auschwitz I that, like the subsequent gas chambers at Auschwitz, used Zyklon B to murder victims. The first transports of Jewish men, women, and children sent to Auschwitz as part of the “final solution” were murdered in this gas chamber (Crematorium I) in February and March 1942.
Then we were fitted out. Strange combinations! The younger and thinner men received, for the most part, old uniforms, even officers' coats without insignia. Others received striped prisoners' garb of relatively light material, a shirt, a pair of socks, and a suit of tissue-thin underwear. No vest, no coat. As headgear there were old soldiers' caps without cockades. It goes without saying that it was very difficult to find clothes fitting the various sizes and shapes. We were a sight grotesque as well as sad.
Primo Levi suggested Anne Frank is frequently identified as a single representative of the millions of people who suffered and died as she did because "One single Anne Frank moves us more than the countless others who suffered just as she did but whose faces have remained in the shadows. Perhaps it is better that way; if we were capable of taking in all the suffering of all those people, we would not be able to live."[82] In her closing message in Müller's biography of Anne Frank, Miep Gies expressed a similar thought, though she attempted to dispel what she felt was a growing misconception that "Anne symbolises the six million victims of the Holocaust", writing: "Anne's life and death were her own individual fate, an individual fate that happened six million times over. Anne cannot, and should not, stand for the many individuals whom the Nazis robbed of their lives ... But her fate helps us grasp the immense loss the world suffered because of the Holocaust."[88]

Nazism’s principal instrument of control was the unification, under Heinrich Himmler and his chief lieutenant, Reinhard Heydrich, of the SS (the uniformed police force of the Nazi Party) and all other police and security organizations. Opposition to the regime was destroyed either by outright terror or, more frequently, by the all-pervading fear of possible repression. Opponents of the regime were branded enemies of the state and of the people, and an elaborate web of informers—often members of the family or intimate friends—imposed utmost caution on all expressions and activities. Justice was no longer recognized as objective but was completely subordinated to the alleged needs and interests of the Volk. In addition to the now-debased methods of the normal judicial process, special detention camps were erected. In these camps the SS exercised supreme authority and introduced a system of sadistic brutality unrivaled in modern times.
Modern Germany fundamentally rejects, and assumes complete responsibility for, the heinous crimes committed under the Third Reich. The Nazis occupy a uniquely menacing place in the Western imagination, the embodiment of humanity’s darkest instincts for racial hatred and barbarism—what Hannah Arendt called “radical evil” in The Origins of Totalitarianism. Whitman uses the word Nefandum, “an abyss of unexampled modern horror against which we can define ourselves.” It is appropriate to be wary of invoking the Nazis, especially in an online environment that has turned the words “Hitler” and “Nazi” into clichés, devaluing their meaning and cheapening the historical lessons to be learned.
Losses continued to mount after Stalingrad, leading to a sharp reduction in the popularity of the Nazi Party and deteriorating morale. [127] Soviet forces continued to push westward after the failed German offensive at the Battle of Kursk in the summer of 1943. By the end of 1943 the Germans had lost most of their eastern territorial gains.[128] In Egypt, Field Marshal Erwin Rommel's Afrika Korps were defeated by British forces under Field Marshal Bernard Montgomery in October 1942.[129] The Allies landed in Sicily in July 1943 and in Italy in September.[130] Meanwhile, American and British bomber fleets based in Britain began operations against Germany. Many sorties were intentionally given civilian targets in an effort to destroy German morale.[131] German aircraft production could not keep pace with losses, and without air cover the Allied bombing campaign became even more devastating. By targeting oil refineries and factories, they crippled the German war effort by late 1944.[132]
Hitler primarily viewed the German economy as an instrument of power and believed the economy was not about creating wealth and technical progress so as to improve the quality of life for a nation's citizenry, but rather that economic success was paramount for providing the means and material foundations necessary for military conquest.[243] While economic progress generated by National Socialist programs had its role in appeasing the German people, the Nazis and Hitler in particular did not believe that economic solutions alone were sufficient to thrust Germany onto the stage as a world power. The Nazis thus sought to secure a general economic revival accompanied by massive military spending for rearmament, especially later through the implementation of the Four Year Plan, which consolidated their rule and firmly secured a command relationship between the German arms industry and the National Socialist government.[244] Between 1933 and 1939, military expenditures were upwards of 82 billion Reichsmarks and represented 23 percent of Germany's gross national product as the Nazis mobilised their people and economy for war.[245]

Memory is not something that is acquired once and stays on forever. The moment that the last eyewitnesses and survivors pass away, we have to work together to build on that which remains: the testimonies of those former prisoners and the authentic artifacts connected with Auschwitz. Each item can have its own enormous meaning and should find its place in the collection of the Auschwitz Memorial. Here, it will be preserved, studied, and displayed. Its place is here. 
Though we tend to think of Hitler’s Germany as a highly regimented dictatorship, in practice Nazi rule was chaotic and improvisatory. Rival power bases in the Party and the German state competed to carry out what they believed to be Hitler’s wishes. This system of “working towards the Fuhrer,” as it was called by Hitler’s biographer Ian Kershaw, was clearly in evidence when it came to the concentration camps. The K.L. system, during its twelve years of existence, included twenty-seven main camps and more than a thousand subcamps. At its peak, in early 1945, it housed more than seven hundred thousand inmates. In addition to being a major penal and economic institution, it was a central symbol of Hitler’s rule. Yet Hitler plays almost no role in Wachsmann’s book, and Wachsmann writes that Hitler was never seen to visit a camp. It was Heinrich Himmler, the head of the S.S., who was in charge of the camp system, and its growth was due in part to his ambition to make the S.S. the most powerful force in Germany.
After Otto returned, he received Anne’s diary from his former employee Hermine Santrouschitz (Miep Gies, b. 1909) who, together with her husband Jan, supplied the occupants of the attic with food, news from the outside and friendship from the day they went into hiding until they were discovered. After the Germans’ raid on the attic Santrouschitz found the diary there and kept it, intending to give it back to Anne when she returned. However, when Otto Frank told her Anne had died she gave it to him and he secluded himself with it for several days. After deep soul-searching and the urging of close friends, and after making some changes of his own, a modest first edition of 1,500 copies was published in Amsterdam in the summer of 1947, on a date close to Anne’s birthday, under the name Het Achterhuis (The Secret Annexe or, literally, The Back House), the name Anne herself had given to all her writings in the attic in which they had hidden. At first the book was unsuccessful; everyone wanted to forget the war and its troubles. But in 1952, after more hesitation on Otto’s part, the diary was published in the United States with a foreword by Eleanor Roosevelt. In 1955 The Diary of Anne Frank, starring Susan Strasberg, opened on Broadway to great acclaim.
From its rise to power in 1933, the Nazi regime built a series of incarceration sites to imprison and eliminate so-called "enemies of the state." Most prisoners in the early concentration camps were German Communists, Socialists, Social Democrats, Roma (Gypsies), Jehovah's Witnesses, homosexuals, and persons accused of "asocial" or socially deviant behavior. Some of these facilities were called “concentration camps” because those imprisoned there were physically “concentrated” in one location.
Although the Germans destroyed parts of the camps before abandoning them in 1945, much of Auschwitz I and Auschwitz II (Birkenau) remained intact and were later converted into a museum and memorial. The site has been threatened by increased industrial activity in Oświęcim. In 1996, however, the Polish government joined with other organizations in a large-scale effort to ensure its preservation. Originally named Auschwitz Concentration Camp, the memorial was designated a UNESCO World Heritage site in 1979. It was renamed “Auschwitz-Birkenau. The Nazi German Concentration and Extermination Camp (1940–1945)” in 2007.
While the Nazis maintained the nominal existence of state and regional governments in Germany itself, this policy was not extended to territories acquired after 1937. Even in German-speaking areas such as Austria, state and regional governments were formally disbanded as opposed to just being dis-empowered. After the Anschluss a new type of administrative unit was introduced called a Reichsgau. In these territories the Gauleiters also held the position of Reichsstatthalter, thereby formally combining the spheres of both party and state offices. The establishment of this type of district was subsequently carried out for any further territorial annexations of Germany both before and during World War II. Even the former territories of Prussia were never formally re-integrated into what was then Germany's largest state after being re-taken in the 1939 Polish campaign.
On 31 July 1941 Hermann Göring gave written authorization to SS-Obergruppenführer Reinhard Heydrich, Chief of the Reich Main Security Office (RSHA), to prepare and submit a plan for a "total solution of the Jewish question" in territories under German control and to coordinate the participation of all involved government organisations.[33] The resulting Generalplan Ost (General Plan for the East) called for deporting the population of occupied Eastern Europe and the Soviet Union to Siberia, for use as slave labour or to be murdered.[34]
