The Nazi Party's precursor, the Pan-German nationalist and antisemitic German Workers' Party, was founded on 5 January 1919. By the early 1920s the party was renamed the National Socialist German Workers' Party – to attract workers away from left-wing parties such as the Social Democrats (SPD) and the Communists (KPD) – and Adolf Hitler assumed control of the organization. The National Socialist Program or "25 Points" was adopted in 1920 and called for a united Greater Germany that would deny citizenship to Jews or those of Jewish descent, while also supporting land reform and the nationalization of some industries. In Mein Kampf ("My Struggle"; 1924–1925), Hitler outlined the anti-Semitism and anti-Communism at the heart of his political philosophy, as well as his disdain for representative democracy and his belief in Germany's right to territorial expansion.[5]
It was a frigid day in occupied Poland, and for all Shmuel Beller knew, it could be his last. As Russian forces advanced toward Auschwitz, Beller and other prisoners had been told by their captors that they had to leave the death camp. So he ran into one of the storage facilities and rifled through a pile of clothing—the belongings of some of the 6,000 Jews gassedeach day at the camp. Finally, he found what he was looking for: a pair of leather shoes.
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]

The cleansing of mouth and teeth was possible only after a two weeks' stay, when we had access to our money and could buy toothbrushes and tooth paste. The towel situation was deplorable. One towel a week was issued for each inmate, but there was no provision for keeping these towels separately. Not unnaturally skin infections, rashes, and boils were frequent. The barracks were heated by iron stoves, some of which were installed only after our admission to the camp, and we had enjoyed them for but a very short time when a sudden restriction denied us the use of them for one week. It was claimed that in one of the 'Jew barracks' the stove had been lighted at a time when it wasn't allowed.

Hitler’s most important individual contribution to the theory and practice of Nazism was his deep understanding of mass psychology and mass propaganda. He stressed the fact that all propaganda must hold its intellectual level at the capacity of the least intelligent of those at whom it is directed and that its truthfulness is much less important than its success. According to Hitler:

On 2 August 1934, Hindenburg died. The previous day, the cabinet had enacted the "Law Concerning the Highest State Office of the Reich", which stated that upon Hindenburg's death the office of president would be abolished and its powers merged with those of the chancellor.[39] Hitler thus became head of state as well as head of government and was formally named as Führer und Reichskanzler ("Leader and Chancellor") – although eventually Reichskanzler was dropped.[40] Germany was now a totalitarian state with Hitler at its head.[41] As head of state, Hitler became Supreme Commander of the armed forces. The new law provided an altered loyalty oath for servicemen so that they affirmed loyalty to Hitler personally rather than the office of supreme commander or the state.[42] On 19 August, the merger of the presidency with the chancellorship was approved by 90 percent of the electorate in a plebiscite.[43]
Auschwitz, Polish Oświęcim, also called Auschwitz-Birkenau, Nazi Germany’s largest concentration camp and extermination camp. Located near the industrial town of Oświęcim in southern Poland (in a portion of the country that was annexed by Germany at the beginning of World War II), Auschwitz was actually three camps in one: a prison camp, an extermination camp, and a slave-labour camp. As the most lethal of the Nazi extermination camps, Auschwitz has become the emblematic site of the “final solution,” a virtual synonym for the Holocaust. Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews. Also among the dead were some 19,000 Roma who were held at the camp until the Nazis gassed them on July 31, 1944—the only other victim group gassed in family units alongside the Jews. The Poles constituted the second largest victim group at Auschwitz, where some 83,000 were killed or died.
The political programme espoused by Hitler and the NSDAP brought about a world war, leaving behind a devastated and impoverished Europe. Germany itself suffered wholesale destruction, characterised as Stunde Null (Zero Hour).[487] The number of civilians killed during the Second World War was unprecedented in the history of warfare.[488] As a result, Nazi ideology and the actions taken by the regime are almost universally regarded as gravely immoral.[489] Historians, philosophers, and politicians often use the word "evil" to describe Hitler and the Nazi regime.[490] Interest in Nazi Germany continues in the media and the academic world. While Evans remarks that the era "exerts an almost universal appeal because its murderous racism stands as a warning to the whole of humanity",[491] young neo-Nazis enjoy the shock value the use Nazi symbols or slogans provides.[492] The display or use of Nazi symbolism such as flags, swastikas, or greetings is illegal in Germany and Austria.[493][494]

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]
The failure of the factory, as Wachsmann describes it, was indicative of the incompetence of the S.S. and the inconsistency of its vision for the camps. To turn prisoners into effective laborers would have required giving them adequate food and rest, not to mention training and equipment. It would have meant treating them like employees rather than like enemies. But the ideological momentum of the camps made this inconceivable. Labor was seen as a punishment and a weapon, which meant that it had to be extorted under the worst possible circumstances. Prisoners were made to build the factory in the depths of winter, with no coats or gloves, and no tools. “Inmates carried piles of sand in their uniforms,” Wachsmann writes, while others “moved large mounds of earth on rickety wooden stretchers or shifted sacks of cement on their shoulders.” Four hundred and twenty-nine prisoners died and countless more were injured, yet in the end not a single brick was produced.
Antisemitic legislation passed in 1933 led to the removal of all Jewish teachers, professors, and officials from the education system. Most teachers were required to belong to the Nationalsozialistischer Lehrerbund (NSLB; National Socialist Teachers League) and university professors were required to join the National Socialist German Lecturers.[349][350] Teachers had to take an oath of loyalty and obedience to Hitler, and those who failed to show sufficient conformity to party ideals were often reported by students or fellow teachers and dismissed.[351][352] Lack of funding for salaries led to many teachers leaving the profession. The average class size increased from 37 in 1927 to 43 in 1938 due to the resulting teacher shortage.[353]

The process of denazification, which was initiated by the Allies as a way to remove Nazi Party members was only partially successful, as the need for experts in such fields as medicine and engineering was too great. However, expression of Nazi views was frowned upon, and those who expressed such views were frequently dismissed from their jobs.[495] From the immediate post-war period through the 1950s, people avoided talking about the Nazi regime or their own wartime experiences. While virtually every family suffered losses during the war has a story to tell, Germans kept quiet about their experiences and felt a sense of communal guilt, even if they were not directly involved in war crimes.[496]

Our trip, full of suspense, took us past the baroque palace of Oranienburg, built at the time of Frederick the Great, through the sand of Brandenburg and through deserted pine forests, thence to a large settlement. Suddenly we saw in front of us high walls (about fourteen feet) which, at intervals of two hundred yards, were crowned by watchtowers, so that the whole camp gave the impression of a Chinese city as we knew it from pictures. We drove through an iron gate, and soon after through a second gate in a second inner wall about a hundred feet from the first one. In the space between the two walls there were barracks with administration and treasury buildings, and vegetable and other gardens. The inner gate, which led through the main watchtower, bore the inscription 'Work Makes Free'—an inscription which many inmates of the camp, after years of work and vain hope for release, will probably take as sarcasm.
The hair of 12 year-old Lili had not been cut since her early childhood. When she and her family were forced to leave their home in Târgu-Mureş and move to the ghetto, Lili’s mother, Rivka, knew she would not be able to care properly for her daughter’s hair in the ghetto. Chopping off Lili’s two long, beautiful braids, she promised that they would be given to the neighbors for safekeeping.Within six weeks, Lili and her mother were murdered at Auschwitz.
From 1942, members of the Bureau of Information and Propaganda of the Warsaw-area Home Army published reports based on the accounts of escapees. The first was a fictional memoir, "Oświęcim. Pamiętnik więźnia" ("Auschwitz: Diary of a prisoner") by Halina Krahelska, published in April 1942 in Warsaw.[206] Also published in 1942 was the pamphlet Obóz śmierci (Camp of Death) by Natalia Zarembina,[207] and W piekle (In Hell) by Zofia Kossak-Szczucka, founder of Żegota.[208] In March 1944, the Polish Labor Group in New York published a report in English, "Oswiecim, Camp of Death (Underground Report)", with a foreword by Florence Jaffray Harriman, which described the gassing of prisoners from 1942.[209]
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]
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.”
Aryan mysticism claimed that Christianity originated in Aryan religious traditions, and that Jews had usurped the legend from Aryans.[80] Houston Stewart Chamberlain, an English-born German proponent of racial theory, supported notions of Germanic supremacy and antisemitism in Germany.[81] Chamberlain's work, The Foundations of the Nineteenth Century (1899), praised Germanic peoples for their creativity and idealism while asserting that the Germanic spirit was threatened by a "Jewish" spirit of selfishness and materialism.[81] Chamberlain used his thesis to promote monarchical conservatism while denouncing democracy, liberalism and socialism.[81] The book became popular, especially in Germany.[81] Chamberlain stressed a nation's need to maintain its racial purity in order to prevent its degeneration and argued that racial intermingling with Jews should never be permitted.[81] In 1923, Chamberlain met Hitler, whom he admired as a leader of the rebirth of the free spirit.[83] Madison Grant's work The Passing of the Great Race (1916) advocated Nordicism and proposed that a eugenics program should be implemented in order to preserve the purity of the Nordic race. After reading the book, Hitler called it "my Bible".[84]
Otto had prepared a secret hideout next to his place of work. The door was hidden behind some bookshelves. The hideout was small. The first floor had a bathroom and a small kitchen. The second floor had two rooms, one for Anne and Margot and one for her parents. There was also an attic where they stored food and where Anne would sometimes go to be alone. 

Auschwitz inmates began working at the plant, known as Buna Werke and IG Auschwitz, in April 1941, and demolishing houses in Monowitz to make way for it. By May, because of a shortage of trucks, several hundred of them were rising at 3 am to walk there twice a day from Auschwitz I.[53] Anticipating that a long line of exhausted inmates walking through the town of Oświęcim might harm German-Polish relations, the inmates were told to shave daily, make sure they were clean, and sing as they walked. From late July they were taken there by train on freight wagons.[54] Because of the difficulty of moving them, including during the winter, IG Farben decided to build a camp at the plant. The first inmates moved there on 30 October 1942.[55] Known as KL Auschwitz III-Aussenlager (Auschwitz III-subcamps), and later as Monowitz concentration camp,[56] it was the first concentration camp to be financed and built by private industry.[57]

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.
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 term was in use before the rise of the party as a colloquial and derogatory word for a backward peasant, an awkward and clumsy person. It derived from Ignaz, a shortened version of Ignatius,[20][21] which was a common name in the Nazis' home region of Bavaria. Opponents seized on this, and the long-existing Sozi, to attach a dismissive nickname to the National Socialists.[21][22]
After 1942, many small subcamps were set up near factories to provide forced labor. IG Farben established a synthetic rubber plant in 1942 at Monowitz concentration camp (Auschwitz III); other camps were set up next to airplane factories, coal mines and rocket propellant plants. Conditions were brutal and prisoners were often sent to the gas chambers or killed on site if they did not work quickly enough.
