All of the extermination camps were thoroughly organised and resembled industrial plants to an alarming degree. However, only Auschwitz-Birkenau, with its advanced gassing facilities and crematoria, was marked by high technology. In crematoria I and II there were elevators from the gas chambers underground, where the Jews were murdered, to the crematoria, where the bodies were burned.

The most infamous doctor at Auschwitz was Josef Mengele, the "Angel of Death", who worked in Auschwitz II from 30 May 1943, at first in the gypsy family camp.[127] Particularly interested in performing research on identical twins, dwarfs, and those with hereditary disease, Mengele set up a kindergarten in barracks 29 and 31 for children he was experimenting on, and for all Romani children under six, where they were given better food rations.[128] From May 1944, he would select twins and dwarfs during selection on the Judenrampe,[129] reportedly calling for twins with "Zwillinge heraus!" ("twins step forward!").[130] He and other doctors (the latter prisoners) would measure the twins' body parts, photograph them, and subject them to dental, sight and hearing tests, x-rays, blood tests, surgery, and blood transfusions between them.[131] Then he would have them killed and dissected.[129] Kurt Heissmeyer, another German doctor and SS officer, took 20 Jewish children from Auschwitz to use in pseudoscientific medical experiments at the Neuengamme concentration camp.[132] In April 1945, the children were killed by hanging to conceal the project.[133]

Entrance is free in general, but visitor numbers are regulated by a ticket system. Be aware that because of the large numbers of visitors, entry to the Auschwitz I site is done exclusively on a paid guided (yet unfortunately rather rushed) tour between 10:00 to 15:00 during the period from 1 April to 31 October. You can visit the site on your own (which is highly recommended, as visitors can go at their own pace, see what they want to see, and have a much more meaningful experience) if you arrive before 10:00 (better 8:00-9:00) or after 15:00 (depending on the season and day of week). This is recommended if you're staying nearby in Katowice or Kraków and don't have your own car, with some trains from Kraków and Katowice Główny arriving between 8-10. Guided tours cost 45PLN (discounted price for students up to 24 years of age is 30PLN). Students with an ISIC card are granted free entrance during tour hours. If you're a small group (~4 or less), it's not too hard to buy tickets on site (but depending on the season, you might have to wait depending on availability), but larger groups should book tickets in advance.
Nazism subscribed to theories of racial hierarchy and Social Darwinism, identifying the Germans as a part of what the Nazis regarded as an Aryan or Nordic master race.[3] It aimed to overcome social divisions and create a German homogeneous society based on racial purity which represented a people's community (Volksgemeinschaft). The Nazis aimed to unite all Germans living in historically German territory, as well as gain additional lands for German expansion under the doctrine of Lebensraum and exclude those who they deemed either community aliens or "inferior" races.

Jewish deportees arriving at Auschwitz-Birkenau immediately underwent selection. The SS staff chose some of the able-bodied for forced labor and sent the rest directly to the gas chambers, which were disguised as shower installations to mislead the victims. The belongings of all deportees were confiscated and sorted in the "Kanada" (Canada) warehouse for shipment back to Germany. Canada symbolized wealth to the prisoners.
The two largest groups of prisoners in the camps, both numbering in the millions, were the Polish Jews and the Soviet prisoners of war (POWs) held without trial or judicial process. There were also large numbers of Romani people, ethnic Poles, Serbs, political prisoners, homosexuals, people with disabilities, Jehovah's Witnesses, Catholic clergy, Eastern European intellectuals and others (including common criminals, as the Nazis declared). In addition, a small number of Western Allied aviators were sent to concentration camps as punishment for spying.[28] Western Allied POWs who were Jews, or who were suspected of being Jews by the Nazis, were usually sent to ordinary POW camps; however, a small number of them were sent to concentration camps because of antisemitic policies.[29]
The Frank sisters each hoped to return to school as soon as they were able, and continued with their studies while in hiding. Margot took a shorthand course by correspondence in Bep Voskuijl's name and received high marks. Most of Anne's time was spent reading and studying, and she regularly wrote and edited her diary entries. In addition to providing a narrative of events as they occurred, she wrote about her feelings, beliefs, and ambitions, subjects she felt she could not discuss with anyone. As her confidence in her writing grew, and as she began to mature, she wrote of more abstract subjects such as her belief in God, and how she defined human nature.[35]
The Auschwitz camp complex has survived largely unchanged since its liberation in January 1945. The remaining camp buildings, structures and infrastructure are a silent witness to history, bearing testimony of the crime of genocide committed by the German Nazis. They are an inseparable part of a death factory organized with precision and ruthless consistency. The attributes that sustain the Outstanding Universal Value of the property are truthfully and credibly expressed, and fully convey the value of the property.
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]

Pseudo-scientific racist theories were central to Nazism, expressed in the idea of a "people's community" (Volksgemeinschaft). The party aimed to unite "racially desirable" Germans as national comrades, while excluding those deemed either to be political dissidents, physically or intellectually inferior, or of a foreign race (Fremdvölkische).[9] The Nazis sought to strengthen the Germanic people, the "Aryan master race", through racial purity and eugenics, broad social welfare programs, and a collective subordination of individual rights, which could be sacrificed for the good of the state on behalf of the people.

The Polish government-in-exile in London first reported the gassing of prisoners in Auschwitz on 21 July 1942,[210] and reported the gassing of Soviet POWs and Jews on 4 September 1942.[211] In 1943, the Kampfgruppe Auschwitz (Combat Group Auschwitz) was organized within the camp with the aim of sending out information about what was happening.[212] Sonderkommandos buried notes in the ground, hoping they would be found by the camp's liberators.[213] The group also smuggled out photographs; the Sonderkommando photographs, of events around the gas chambers in Auschwitz II, were smuggled out of the camp in September 1944 in a toothpaste tube.[214] According to Fleming, the British press responded, in 1943 and the first half of 1944, either by not publishing reports about Auschwitz or by burying them on the inside pages. The exception was the Polish Jewish Observer, published as a supplement to the City and East London Observer and edited by Joel Cang, a former Warsaw correspondent for the Manchester Guardian. The British reticence stemmed from a Foreign Office concern that the public might pressure the government to respond or provide refuge for the Jews, and that British actions on behalf of the Jews might affect its relationships in the Middle East. There was similar reticence in the United States, and indeed within the Polish government-in-exile and the Polish resistance. According to Fleming, the scholarship suggests that the Polish resistance distributed information about the Holocaust in Auschwitz without challenging the Allies' reluctance to highlight it.[215]
And it means deploying conservators to preserve an inventory that includes more than a ton of human hair; 110,000 shoes; 3,800 suitcases; 470 prostheses and orthopedic braces; more than 88 pounds of eyeglasses; hundreds of empty canisters of Zyklon B poison pellets; patented metal piping and showerheads for the gas chambers; hundreds of hairbrushes and toothbrushes; 379 striped uniforms; 246 prayer shawls; more than 12,000 pots and pans carried by Jews who believed that they were simply bound for resettlement; and some 750 feet of SS documents — hygiene records, telegrams, architectural blueprints and other evidence of the bureaucracy of genocide — as well as thousands of memoirs by survivors.
Chelmno was the first extermination camp to be established as part of the ‘Final Solution to the Jewish Question’ – the Nazis’ systematic effort to exterminate the Jews.  This was quickly followed by the establishment of three more extermination camps: Belzec, Treblinka and Sobibor. They were established under the code-name Operation Reinhard – the starting signal to the extermination of the approximately 3 million Jews who lived in Nazi-occupied Poland. In the concentration camps Auschwitz-Birkenau and Majdanek two further extermination camps were established.
The general membership of the Nazi Party mainly consisted of the urban and rural lower middle classes. 7% belonged to the upper class, another 7% were peasants, 35% were industrial workers and 51% were what can be described as middle class. In early 1933, just before Hitler's appointment to the chancellorship, the party showed an under-representation of "workers", who made up 29.7% of the membership but 46.3% of German society. Conversely, white-collar employees (18.6% of members and 12% of Germans), the self-employed (19.8% of members and 9.6% of Germans) and civil servants (15.2% of members and 4.8% of the German population) had joined in proportions greater than their share of the general population.[115] These members were affiliated with local branches of the party, of which there were 1,378 throughout the country in 1928. In 1932, the number had risen to 11,845, reflecting the party's growth in this period.[115]

The Soviet occupation of eastern Poland in 1939 and the absorption of the Baltic states in 1940 led to the incarceration of large numbers of non-Soviet citizens. Following the outbreak of war with Germany in 1941, the camps received Axis prisoners of war and Soviet nationals accused of collaboration with the enemy. After the death of Joseph Stalin in 1953, many prisoners were released and the number of camps was drastically reduced. See also Gulag.

Wonderful book, the like of which I haven't seen elsewhere. So many wonderful passages, insights into life such as you rarely find anywhere. Anne's ruminations captured here were for herself, from the heart. Writing this helped so much in making her life tolerable during this very difficult period in her life. Toward the end, I found it difficult to plow to the end, knowing that she tragically did not survive. However, she was unaware that their arrest was imminent, so the unfortunate ending is not implicit in Anne's writing. She just may as well have survived and gone on to have the wonderful life and career she very much deserved. I have read a lot about WW II, but this book succeeded in doing what all the other readings did not for me -- it made me feel that I was living through it myself.
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]

Authors of books left the country in droves and some wrote material critical of the regime while in exile. Goebbels recommended that the remaining authors concentrate on books themed on Germanic myths and the concept of blood and soil. By the end of 1933, over a thousand books—most of them by Jewish authors or featuring Jewish characters—had been banned by the Nazi regime.[464] Nazi book burnings took place; nineteen such events were held on the night of 10 May 1933.[458] Tens of thousands of books from dozens of figures, including Albert Einstein, Sigmund Freud, Helen Keller, Alfred Kerr, Marcel Proust, Erich Maria Remarque, Upton Sinclair, Jakob Wassermann, H. G. Wells, and Émile Zola were publicly burned. Pacifist works, and literature espousing liberal, democratic values were targeted for destruction, as well as any writings supporting the Weimar Republic or those written by Jewish authors.[465]
A Nazi era school textbook for German students entitled Heredity and Racial Biology for Students written by Jakob Graf described to students the Nazi conception of the Aryan race in a section titled "The Aryan: The Creative Force in Human History".[136] Graf claimed that the original Aryans developed from Nordic peoples who invaded ancient India and launched the initial development of Aryan culture there that later spread to ancient Persia and he claimed that the Aryan presence in Persia was what was responsible for its development into an empire.[136] He claimed that ancient Greek culture was developed by Nordic peoples due to paintings of the time which showed Greeks who were tall, light-skinned, light-eyed, blond-haired people.[136] He said that the Roman Empire was developed by the Italics who were related to the Celts who were also a Nordic people.[136] He believed that the vanishing of the Nordic component of the populations in Greece and Rome led to their downfall.[136] The Renaissance was claimed to have developed in the Western Roman Empire because of the Germanic invasions that brought new Nordic blood to the Empire's lands, such as the presence of Nordic blood in the Lombards (referred to as Longobards in the book); that remnants of the western Goths were responsible for the creation of the Spanish Empire; and that the heritage of the Franks, Goths and Germanic peoples in France was what was responsible for its rise as a major power.[136] He claimed that the rise of the Russian Empire was due to its leadership by people of Norman descent.[136] He described the rise of Anglo-Saxon societies in North America, South Africa and Australia as being the result of the Nordic heritage of Anglo-Saxons.[136] He concluded these points by saying: "Everywhere Nordic creative power has built mighty empires with high-minded ideas, and to this very day Aryan languages and cultural values are spread over a large part of the world, though the creative Nordic blood has long since vanished in many places".[136]

Although the Nazis won the greatest share of the popular vote in the two Reichstag general elections of 1932, they did not have a majority. Hitler therefore led a short-lived coalition government formed with the German National People's Party.[14] Under pressure from politicians, industrialists, and the business community, President Paul von Hindenburg appointed Hitler as Chancellor of Germany on 30 January 1933. This event is known as the Machtergreifung ("seizure of power").[15]

There is an exculpatory ease to embracing this “young girl,” whose murder is almost as convenient for her many enthusiastic readers as it was for her persecutors, who found unarmed Jewish children easier to kill off than the Allied infantry. After all, an Anne Frank who lived might have been a bit upset at the Dutch people who, according to the leading theory, turned in her household and received a reward of approximately $1.40 per Jew. An Anne Frank who lived might not have wanted to represent “the children of the world,” particularly since so much of her diary is preoccupied with a desperate plea to be taken seriously—to not be perceived as a child. Most of all, an Anne Frank who lived might have told people about what she saw at Westerbork, Auschwitz and Bergen-Belsen, and people might not have liked what she had to say.
On 23 March, the parliament passed the Enabling Act of 1933, which gave the cabinet the right to enact laws without the consent of parliament. In effect, this gave Hitler dictatorial powers. Now possessing virtually absolute power, the Nazis established totalitarian control as they abolished labour unions and other political parties and imprisoned their political opponents, first at wilde Lager, improvised camps, then in concentration camps. Nazi Germany had been established, yet the Reichswehr remained impartial. Nazi power over Germany remained virtual, not absolute.
On 26 June 1933, Himmler appointed Theodor Eicke commandant of Dachau, who in 1934 was also appointed the first Inspector of Concentration Camps (CCI). In addition, the remaining SA-run camps were taken over by the SS.[14][15][16] Dachau served as both a prototype and a model for the other Nazi concentration camps. Almost every community in Germany had members who were taken there. The newspapers continuously reported on "the removal of the enemies of the Reich to concentration camps" making the general population more aware of their presence. There were jingles warning as early as 1935: "Dear God, make me dumb, that I may not come to Dachau."[17]
