Originally an Austro-Hungarian and later a Polish Army barracks before the start of the Second World War, the invading Nazis assumed authority over the military facility following the region's annexation by the Third Reich in 1939. The neighboring town's name of Oświęcim was Germanized to Auschwitz, which also became the name of the camp. Beginning in 1940, all Polish and Jewish residents of Oświęcim were expelled, replaced by German settlers, whom the Third Reich planned to make a model community. The camp began operations on 14 June 1940, originally housing Polish political prisoners, who made up a majority of the camp's population until 1942. Poles were treated with extreme brutality, with more than half of the 130-150,000 Polish inmates dying.
Another reactionary aspect of Nazism was in their arts policy, which stemmed from Hitler's rejection of all forms of "degenerate" modern art, music and architecture.[286] Overall, however, Nazism – being the ideology and practices of the Nazi Party, and the Nazi Party being the manifestation of Hitler's will[287] – is best seen as essentially revolutionary in nature.
The process of selection and murder was carefully planned and organized. When a train stopped at the platform, veteran prisoners received the victims and gathered their belongings in several barracks in an area known as “Kanada.” The arrivals were lined up in two columns – men and boys in one, women and girls in the other – and SS physicians performed a selection.  The criterion was the appearance of the prisoners, whose fate, for labor or for death, was determined at will. Before they entered the chamber, they were told that they were about to be disinfected and ordered to undress. The doors of the chamber were locked and the gas was introduced. After the victims were murdered, their gold teeth were extracted and women’s hair was shorn by the Sonderkommando – groups of Jews forced to work in the crematoria. The bodies were hauled to the crematorium furnaces for incineration, the bones were pulverized and the ashes were scattered in the fields.
In November 2015 the Swiss foundation which owns the rights to The Diary of Anne Frank, the Anne Frank Fonds, added Frank's father, Otto, as a co-author. Otto was added as an author to extend the copyright of the work, which would have expired on December 31, 2015, 70 years after Anne's death. If the authorship change goes unchallenged, the new copyright will allow Anne Frank Fonds to retain control of publication of the diary until 2050. Legal experts advised officials at the Anne Frank Fonds that adding Frank's father Otto as a co-author was justified, because he helped put together the final draft of the diary and “created new work” by editing and reshaping it.
Only after the true scope of the Holocaust’s horrors were known did the world begin to react to what had happened at Auschwitz. Though the Nazis fled and tried to cover up their deeds, making it impossible to ever know the complete history of their crimes, the voices of the victims and survivors live on through their testimony. All in all, 6 million Jews perished in the Holocaust. Today, a museum and memorial at Auschwitz preserves the remnants of the Nazis’ crimes—a reminder of the many who were killed and a testament to those who survived.

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

The prisoners' days began at 4:30 am for the men (an hour later in winter), and earlier for the women, when the block supervisor sounded a gong and started beating inmates with sticks to encourage them to wash and use the latrines quickly.[106] Sanitary arrangements were atrocious, with few latrines and a lack of clean water. Each washhouse had to service thousands of prisoners. In sectors BIa and BIb in Auschwitz II-Birkenau, two buildings containing latrines and washrooms were installed in 1943. These contained troughs for washing and 90 faucets; the toilet facilities were "sewage channels" covered by concrete with 58 holes for seating. There were three barracks with washing facilities or toilets to serve 16 residential barracks in BIIa, and six washrooms/latrines for 32 barracks in BIIb, BIIc, BIId, and BIIe.[107] Primo Levi described a 1944 Auschwitz III washroom:
In March 1933, the Enabling Act, an amendment to the Weimar Constitution, passed in the Reichstag by a vote of 444 to 94.[17] This amendment allowed Hitler and his cabinet to pass laws—even laws that violated the constitution—without the consent of the president or the Reichstag.[18] As the bill required a two-thirds majority to pass, the Nazis used intimidation tactics as well as the provisions of the Reichstag Fire Decree to keep several Social Democratic deputies from attending, and the Communists had already been banned.[19][20] On 10 May, the government seized the assets of the Social Democrats, and they were banned on 22 June.[21] On 21 June, the SA raided the offices of the German National People's Party – their former coalition partners – and they disbanded on 29 June. The remaining major political parties followed suit. On 14 July 1933 Germany became a one-party state with the passage of a law decreeing the NSDAP to be the sole legal party in Germany. The founding of new parties was also made illegal, and all remaining political parties which had not already been dissolved were banned.[22] The Enabling Act would subsequently serve as the legal foundation for the dictatorship the NSDAP established.[23] Further elections in November 1933, 1936, and 1938 were Nazi-controlled, with only members of the NSDAP and a small number of independents elected.[24]

If Godwin has a law clerk, she is working overtime this week. I refer to the truism Godwin’s Law: that all arguments eventually end with Hitler and the Holocaust. Everyone, it seems, is hurling comparisons between the American detention centers housing refugee children at the Mexican border and Nazi concentration camps. Former CIA director Michael Hayden tweeted an image of Auschwitz-Birkenau with the message, “Other governments have separated mothers and children.”
Nazism attempted to reconcile conservative, nationalist ideology with a socially radical doctrine. In so doing, it became a profoundly revolutionary movement—albeit a largely negative one. Rejecting rationalism, liberalism, democracy, the rule of law, human rights, and all movements of international cooperation and peace, it stressed instinct, the subordination of the individual to the state, and the necessity of blind and unswerving obedience to leaders appointed from above. It also emphasized the inequality of men and races and the right of the strong to rule the weak; sought to purge or suppress competing political, religious, and social institutions; advanced an ethic of hardness and ferocity; and partly destroyed class distinctions by drawing into the movement misfits and failures from all social classes. Although socialism was traditionally an internationalist creed, the radical wing of Nazism knew that a mass base existed for policies that were simultaneously anticapitalist and nationalist. However, after Hitler secured power, this radical strain was eliminated.
Nazism had peculiarly German roots. It can be partly traced to the Prussian tradition as developed under Frederick William I (1688–1740), Frederick the Great (1712–68), and Otto von Bismarck (1815–98), which regarded the militant spirit and the discipline of the Prussian army as the model for all individual and civic life. To it was added the tradition of political romanticism, with its sharp hostility to rationalism and to the principles underlying the French Revolution, its emphasis on instinct and the past, and its proclamation of the rights of Friedrich Nietzsche’s exceptional individual (the Übermensch [“Superman”]) over all universal law and rules. These two traditions were later reinforced by the 19th-century adoration of science and of the laws of nature, which seemed to operate independently of all concepts of good and evil. Further reinforcements came from such 19th-century intellectual figures as the comte de Gobineau (1816–82), Richard Wagner (1813–83), and Houston Stewart Chamberlain (1855–1927), all of whom greatly influenced early National Socialism with their claims of the racial and cultural superiority of the “Nordic” (Germanic) peoples over all other Europeans and all other races.
On the morning of 4 August 1944, the Achterhuis was stormed by a group of German uniformed police (Grüne Polizei) led by SS-Oberscharführer Karl Silberbauer of the Sicherheitsdienst.[37] The Franks, van Pelses, and Pfeffer were taken to RSHA headquarters, where they were interrogated and held overnight. On 5 August they were transferred to the Huis van Bewaring (House of Detention), an overcrowded prison on the Weteringschans. Two days later they were transported to the Westerbork transit camp, through which by that time more than 100,000 Jews, mostly Dutch and German, had passed. Having been arrested in hiding, they were considered criminals and sent to the Punishment Barracks for hard labour.[38]
In Mein Kampf, Hitler stated his desire to "make war upon the Marxist principle that all men are equal."[248] He believed that "the notion of equality was a sin against nature."[249] Nazism upheld the "natural inequality of men," including inequality between races and also within each race.[52] The National Socialist state aimed to advance those individuals with special talents or intelligence, so they could rule over the masses.[52] Nazi ideology relied on elitism and the Führerprinzip (leadership principle), arguing that elite minorities should assume leadership roles over the majority, and that the elite minority should itself be organized according to a "hierarchy of talent," with a single leader - the Führer - at the top.[250] The Führerprinzip held that each member of the hierarchy owed absolute obedience to those above him and should hold absolute power over those below him.[53]
In the 1920s, political opponents of the NSDAP in the German labour movement seized on this and – using the earlier abbreviated term "Sozi" for Sozialist (English: Socialist) as an example[8] – shortened the first part of the NSDAP's name, Nationalsozialistische, to the dismissive "Nazi", in order to associate them with the derogatory use of the term mentioned above.[9][7][10][11][12][13]

A useful analogy requires that we move beyond a Google image search and truly interrogate history. If we do, we may arrive at the Camp de Rivesaltes, an ad hoc facility created from an empty military camp in southern France. Its first prisoners in 1938 were not Jews but Spanish refugees who had fought against Francisco Franco’s victorious fascists. They were fleeing inevitable persecution from the Spanish dictator. The goal of that temporary concentration camp was to prevent the further dispersion of the Spanish refugees and their settlement in France while a repatriation solution was found. It never was.
The gas chambers in the Auschwitz complex constituted the largest and most efficient extermination method employed by the Nazis. Four chambers were in use at Birkenau, each with the potential to kill 6,000 people daily. They were built to look like shower rooms in order to confuse the victims. New arrivals at Birkenau were told that they were being sent to work, but first needed to shower and be disinfected. They would be led into the shower-like chambers, where they were quickly gassed to death with the highly poisonous Zyklon B gas.

Several SS personnel oversaw the killings at each gas chamber, while the bulk of the work was done by the mostly Jewish prisoners known as Sonderkommandos (special squads).[91][92] Hungarian doctor Miklós Nyiszli reported that the Sonderkommando numbered around 860 prisoners when the Hungarian Jews were being killed in May–July 1944.[93] Their responsibilities included removing goods and corpses from the incoming trains, guiding victims to the dressing rooms and gas chambers, and working in the "Canada" barracks, where the victims' possessions were stored.[94] Housed separately from other prisoners, in somewhat better conditions, their quality of life was further improved by access to the goods taken from murdered prisoners, which they were sometimes able to steal and trade on Auschwitz's black market.[95] Many Sonderkommandos committed suicide in response to the horrors of their work; others were generally shot by the SS in a matter of weeks. New Sonderkommando units were formed from incoming transports. Almost none of the 2,000 prisoners placed in these units survived to the camp's liberation.[96]
With its sections separated by barbed-wire fences, Auschwitz II had the largest prisoner population of any of the three main camps. In January 1942, the first chamber using lethal Zyklon B gas was built on the camp. This building was judged inadequate for killing on the scale the Nazis wanted, and four further chambers were built. These were used for systematic genocide right up until November 1944, two months before the camp was liberated.
Hitler spoke of Nazism being indebted to the success of Fascism's rise to power in Italy.[125] In a private conversation in 1941, Hitler said that "the brown shirt would probably not have existed without the black shirt", the "brown shirt" referring to the Nazi militia and the "black shirt" referring to the Fascist militia.[125] He also said in regards to the 1920s: "If Mussolini had been outdistanced by Marxism, I don't know whether we could have succeeded in holding out. At that period National Socialism was a very fragile growth".[125]
Nazi Germany had a strong anti-tobacco movement, as pioneering research by Franz H. Müller in 1939 demonstrated a causal link between smoking and lung cancer.[389] The Reich Health Office took measures to try to limit smoking, including producing lectures and pamphlets.[390] Smoking was banned in many workplaces, on trains, and among on-duty members of the military.[391] Government agencies also worked to control other carcinogenic substances such as asbestos and pesticides.[392] As part of a general public health campaign, water supplies were cleaned up, lead and mercury were removed from consumer products, and women were urged to undergo regular screenings for breast cancer.[393]

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]
Military trucks loaded with bread arrived on 28 January, and volunteers began to offer first aid and improvised assistance the following week.[250] The liberation of the camp received little Western press attention at the time. Laurence Rees attributes this to three factors: the previous discovery of similar crimes at the Majdanek concentration camp, competing news from the Allied summit at Yalta, and the Soviet Union's Marxist presentation of the camp "as the ultimate capitalist factory where the workers were dispensible", combined with its interest in minimizing attention to Jewish suffering.[253]
After Nazi Germany unleashed World War II in September 1939, vast new territorial conquests and larger groups of potential prisoners led to the rapid expansion of the concentration camp system to the east. The war did not change the original function of the concentration camps as detention sites for the incarceration of political enemies. The climate of national emergency that the conflict granted to the Nazi leaders, however, permitted the SS to expand the functions of the camps.
Nazi Germany maintained concentration camps (German: Konzentrationslager, KZ or KL) throughout the territories it controlled before and during the Second World War. The first Nazi camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control of the police by Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring.[2] Used to hold and torture political opponents and union organizers, the camps initially held around 45,000 prisoners.[3] In 1933–1939, before the onset of war, most prisoners consisted of German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans.[4]
