Those deemed fit enough for slave labor were then immediately registered, tattooed with a serial number, undressed, deloused, had their body hair shaven off, showered while their clothes were disinfected with Zyklon-B gas, and entered the camp under the infamous gateway inscribed “Arbeit Macht Frei” (“Labor will set you free”). Of approximately 2.5 million people who were deported to Auschwitz, 405,000 were given prisoner status and serial numbers. Of these, approximately 50% were Jews and 50% were Poles and other nationalities.
Hitler was appointed Chancellor of Germany by the President of the Weimar Republic, Paul von Hindenburg, on 30 January 1933. The NSDAP then began to eliminate all political opposition and consolidate its power. Hindenburg died on 2 August 1934 and Hitler became dictator of Germany by merging the offices and powers of the Chancellery and Presidency. A national referendum held 19 August 1934 confirmed Hitler as sole Führer (leader) of Germany. All power was centralised in Hitler's person and his word became the highest law. The government was not a coordinated, co-operating body, but a collection of factions struggling for power and Hitler's favour. In the midst of the Great Depression, the Nazis restored economic stability and ended mass unemployment using heavy military spending and a mixed economy. Extensive public works were undertaken, including the construction of Autobahnen (motorways). The return to economic stability boosted the regime's popularity.
Historian Michael Burleigh claims that Nazism used Christianity for political purposes, but such use required that "fundamental tenets were stripped out, but the remaining diffuse religious emotionality had its uses".[215] Burleigh claims that Nazism's conception of spirituality was "self-consciously pagan and primitive".[215] However, historian Roger Griffin rejects the claim that Nazism was primarily pagan, noting that although there were some influential neo-paganists in the Nazi Party, such as Heinrich Himmler and Alfred Rosenberg, they represented a minority and their views did not influence Nazi ideology beyond its use for symbolism. It is noted that Hitler denounced Germanic paganism in Mein Kampf and condemned Rosenberg's and Himmler's paganism as "nonsense".[216]
Otto Frank gave the diary to the historian Annie Romein-Verschoor, who tried unsuccessfully to have it published. She then gave it to her husband Jan Romein, who wrote an article about it, titled "Kinderstem" ("A Child's Voice"), which was published in the newspaper Het Parool on 3 April 1946. He wrote that the diary "stammered out in a child's voice, embodies all the hideousness of fascism, more so than all the evidence at Nuremberg put together."[69] His article attracted attention from publishers, and the diary was published in the Netherlands as Het Achterhuis (The Annex) in 1947,[70] followed by five more printings by 1950.[71]
Between 1942 and 1944, the SS authorities at Auschwitz established 44 subcamps. Some of them were established within the officially designated “development” zone, including Budy, Rajsko, Tschechowitz, Harmense, and Babitz. Others, such as Blechhammer, Gleiwitz, Althammer, Fürstengrube, Laurahuette, and Eintrachthuette were located in Upper Silesia north and west of the Vistula River. Some subcamps, such as Freudenthal and Bruenn (Brno), were located in Moravia.
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]

In early November 1944, Anne was put on transport again. Together with her sister, she was deported to the Bergen-Belsen concentration camp. Her parents stayed behind in Auschwitz. The conditions in Bergen-Belsen were horrible, too, there was a lack of food, it was cold, and Anne, like her sister, contracted typhus. In February 1945 they both died owing to its effects, Margot first, Anne shortly afterwards. 
By then, Auschwitz was serving as both a slave labor facility and a death camp. As the Germans brought more and more Jews from all over Europe to the sprawling complex, SS doctors selected the fittest for work. Other prisoners were sent directly to Birkenau’s gas chambers for what was euphemistically known as a special action. “Was present for first time at a special action at 3 a.m. By comparison Dante’s Inferno seems almost a comedy,” SS doctor Johann Paul Kremer wrote in his diary on September 2, 1942. Camp records show the transport he observed contained 957 Jews from France; only 12 men and 27 women were selected for work.
In Nazi Germany, the idea of creating a master race resulted in efforts to "purify" the Deutsche Volk through eugenics and its culmination was the compulsory sterilization or the involuntary euthanasia of physically or mentally disabled people. After World War II, the euthanasia programme was named Action T4.[144] The ideological justification for euthanasia was Hitler's view of Sparta (11th century – 195 BC) as the original Völkisch state and he praised Sparta's dispassionate destruction of congenitally deformed infants in order to maintain racial purity.[145][146] Some non-Aryans enlisted in Nazi organisations like the Hitler Youth and the Wehrmacht, including Germans of African descent[147] and Jewish descent.[148] The Nazis began to implement "racial hygiene" policies as soon as they came to power. The July 1933 "Law for the Prevention of Hereditarily Diseased Offspring" prescribed compulsory sterilization for people with a range of conditions which were thought to be hereditary, such as schizophrenia, epilepsy, Huntington's chorea and "imbecility". Sterilization was also mandated for chronic alcoholism and other forms of social deviance.[149] An estimated 360,000 people were sterilised under this law between 1933 and 1939. Although some Nazis suggested that the programme should be extended to people with physical disabilities, such ideas had to be expressed carefully, given the fact that some Nazis had physical disabilities, one example being one of the most powerful figures of the regime, Joseph Goebbels, who had a deformed right leg.[150]
The 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.[321] To determine who should be killed, Himmler created the Volksliste, a system of classification of people deemed to be of German blood.[322] He ordered that those of Germanic descent who refused to be classified as ethnic Germans should be deported to concentration camps, have their children taken away, or be assigned to forced labour.[323][324] The plan also included the kidnapping of children deemed to have Aryan-Nordic traits, who were presumed to be of German descent.[325] The goal was to implement Generalplan Ost after the conquest of the Soviet Union, but when the invasion failed Hitler had to consider other options.[321][326] One suggestion was a mass forced deportation of Jews to Poland, Palestine, or Madagascar.[317]
The Auschwitz camp itself covers 50 acres and comprises 46 historical buildings, including two-story red brick barracks, a kitchen, a crematorium and several brick and concrete administration buildings. In addition, Birkenau, a satellite camp about two miles away, sprawls over more than 400 acres and has 30 low-slung brick barracks and 20 wooden structures, railroad tracks and the remains of four gas chambers and crematoria. In total, Banas and her staff monitor 150 buildings and more than 300 ruins at the two sites.
Frank soon found the traction to publish Margot, a novel that imagined her sister living the life she once dreamed of, as a midwife in the Galilee. A surreal work that breaks the boundaries between novel and memoir, and leaves ambiguous which of its characters are dead or alive, Margot became wildly popular in Israel. Its English translation allowed Frank to find a small but appreciative audience in the United States.

What is and what is not well written: It is likely that Frank’s opinions on the subject would have evolved if she had had the opportunity to age. Reading the diary as an adult, one sees the limitations of a teenager’s perspective, and longs for more. In one entry, Frank describes how her father’s business partners—now her family’s protectors—hold a critical corporate meeting in the office below the family’s hiding place. Her father, she and her sister discover that they can hear what is said by lying down with their ears pressed to the floor. In Frank’s telling, the episode is a comic one; she gets so bored that she falls asleep. But adult readers cannot help but ache for her father, a man who clawed his way out of bankruptcy to build a business now stolen from him, reduced to lying face-down on the floor just to overhear what his subordinates might do with his life’s work. When Anne Frank complains about her insufferable middle-aged roommate Fritz Pfeffer (Albert Dussel, per Frank’s pseudonym) taking his time on the toilet, adult readers might empathize with him as the only single adult in the group, permanently separated from his non-Jewish life partner whom he could not marry due to anti-Semitic laws. Readers Frank’s age connect with her budding romance with fellow hidden resident Peter van Pels (renamed Peter van Daan), but adults might wonder how either of the married couples in the hiding place managed their own relationships in confinement with their children. Readers Frank’s age relate to her constant complaints about grown-ups and their pettiness, but adult readers are equipped to appreciate the psychological devastation of Frank’s older subjects, how they endured not only their physical deprivation, but the greater blow of being reduced to a childlike dependence on the whims of others.

The Allied powers organised war crimes trials, beginning with the Nuremberg trials, held from November 1945 to October 1946, of 23 top Nazi officials. They were charged with four counts—conspiracy to commit crimes, crimes against peace, war crimes and crimes against humanity—in violation of international laws governing warfare.[483] All but three of the defendants were found guilty and twelve were sentenced to death.[484] Twelve Subsequent Nuremberg trials of 184 defendants were held between 1946 and 1949.[483] Between 1946 and 1949, the Allies investigated 3,887 cases, of which 489 were brought to trial. The result was convictions of 1,426 people; 297 of these were sentenced to death and 279 to life in prison, with the remainder receiving lesser sentences. About 65 percent of the death sentences were carried out.[485] Poland was more active than other nations in investigating war crimes, for example prosecuting 673 of the total 789 Auschwitz staff brought to trial.[486]
I worked out pretty quickly certain survival tricks. That if the guards called us to line up in front of the barracks, I should hide or sneak into another barracks. The safest place I could find to hide was in the yard near the bathrooms where all the dead bodies were brought and piled up … I would get on the pile, lie down next to the dead bodies and pretend I was one of them.
POW camps (Kriegsgefangenen-Mannschafts-Stammlager / Stalag) a.k.a. Main Camps for Enlisted Prisoners of War: concentration camps where enlisted prisoners-of-war were held after capture. The inmates were usually assigned soon to nearby labor camps, (Arbeitskommandos), i.e. the Work Details. POW officers had their own camps (Offizierslager' / Oflag). Stalags were for Army prisoners, but specialized camps (Marinelager / Marlag ("Navy camps") and Marineinterniertenlager / Milag ("Merchant Marine Internment Camps")) existed for the other services. Kriegsgefangenen-Mannschafts-Stammlager Luftwaffe / Stalag Luft ("Air Forces Camps") were the only camps that detained both officers and non-commissioned personnel together.
Nazism emphasized German nationalism, including both irredentism and expansionism. Nazism held racial theories based upon a belief in the existence of an Aryan master race that was superior to all other races. The Nazis emphasised the existence of racial conflict between the Aryan race and others—particularly Jews, whom the Nazis viewed as a mixed race that had infiltrated multiple societies and was responsible for exploitation and repression of the Aryan race. The Nazis also categorised Slavs as Untermensch (sub-human).[129]
Via the offices of the Sicherheitsdienst, the German security police, prison in Amsterdam, and the Westerbork transit camp, the people from the Secret Annex were put on transport to the Auschwitz-Birkenau concentration and extermination camp. The train journey took three days, during which Anne and over a thousand others were packed closely together in cattle wagons. There was little food and water and only a barrel for a toilet. 
Radical Antisemitism was promoted by prominent advocates of Völkisch nationalism, including Eugen Diederichs, Paul de Lagarde and Julius Langbehn.[69] De Lagarde called the Jews a "bacillus, the carriers of decay ... who pollute every national culture ... and destroy all faiths with their materialistic liberalism" and he called for the extermination of the Jews.[89] Langbehn called for a war of annihilation against the Jews, and his genocidal policies were later published by the Nazis and given to soldiers on the front during World War II.[89] One antisemitic ideologue of the period, Friedrich Lange, even used the term "National Socialism" to describe his own anti-capitalist take on the Völkisch nationalist template.[90]

Auschwitz became one of the camps used for the mass extermination of Jews. In summer 1941, Heinrich Himmler gave orders to Auschwitz commander Rudolf Höß to build a centre at Auschwitz for the mass murder of Jews. In September 1941, the lethal effects of Zyklon B - a substance normally used for pest control - were first tested and verified there. Later, four large gas chambers were built at Birkenau, capable of killing up to six thousand people each day. The gas chambers were disguised as showers, meant to persuade the victims that these were disinfection measures which they had to undergo before they were sent to work in the camp.

The lead editors of the Encyclopedia of Camps and Ghettos, 1933–1945 of the United States Holocaust Memorial Museum, Geoffrey Megargee and Martin Dean, cataloged some 42,500 Nazi ghettos and camps throughout Europe, spanning German-controlled areas from France to Russia and Germany itself, operating from 1933 to 1945. They estimate that 15 million to 20 million people died or were imprisoned in the sites.[36]
