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]
This complex incorporated 45 forced labor sub-camps. The name Buna was based on the Buna synthetic rubber factory on site, owned by I.G. Farben, Germany’s largest chemical company. Most workers at this and other German-owned factories were Jewish inmates. The labor would push inmates to the point of total exhaustion, at which time new laborers replaced them.
To help carry out the "Final Solution" (the genocide or mass destruction of Jews), the Nazis established killing centers in German-occupied  Poland, the country with the largest Jewish population. Killing centers were designed for efficient mass murder. The first one, which opened in December 1941, was Chelmno, where Jews and Roma were gassed in mobile gas vans. In 1942, the Nazis opened the Belzec, Sobibor, and Treblinka killing centers to systematically murder the Jews of the Generalgouvernement (the territory in the interior of German-occupied Poland).

Spengler's notions of "Prussian socialism" as described in his book Preussentum und Sozialismus ("Prussiandom and Socialism", 1919), influenced Nazism and the Conservative Revolutionary movement.[110] Spengler wrote: "The meaning of socialism is that life is controlled not by the opposition between rich and poor, but by the rank that achievement and talent bestow. That is our freedom, freedom from the economic despotism of the individual".[110] Spengler adopted the anti-English ideas addressed by Plenge and Sombart during World War I that condemned English liberalism and English parliamentarianism while advocating a national socialism that was free from Marxism and that would connect the individual to the state through corporatist organisation.[109] Spengler claimed that socialistic Prussian characteristics existed across Germany, including creativity, discipline, concern for the greater good, productivity and self-sacrifice.[112] He prescribed war as a necessity by saying: "War is the eternal form of higher human existence and states exist for war: they are the expression of the will to war".[113]
A parallel system operated later at Birkenau in 1942-43, except that for the majority the 'showers' proved to be gas chambers. Only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the 'central sauna' before being assigned barracks. In May 1944, a spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944.
Beginning in April 1933, scores of measures defining the status of Jews and their rights were instituted.[49] These measures culminated in the establishment of the Nuremberg Laws of 1935, which stripped them of their basic rights.[50] The Nazis would take from the Jews their wealth, their right to intermarry with non-Jews, and their right to occupy many fields of labour (such as law, medicine, or education). Eventually the Nazis declared the Jews as undesirable to remain among German citizens and society.[51]
From the end of March 1942, Jewish transports from Nazi-ruled countries flowed into Auschwitz. Jews from Slovakia and France were deported there first, followed by Dutch Jews from July 1942, and from August, Jews from Belgium and Yugoslavia. Between October 1942 and October 1944, over 46 000 prisoners were deported from Terezín to Auschwitz. Some of them were put in the „Terezín family camp“ for a temporary period. Throughout 1943, transports were sent to Auschwitz from Germany and other countries in the Nazi sphere of power. The victims of the last great wave of deportations to Auschwitz were the Jews of Hungary, who were deported between May and July 1944.
Initially a small bodyguard unit under the auspices of the SA, the Schutzstaffel (SS; Protection Squadron) grew to become one of the largest and most powerful groups in Nazi Germany.[232] Led by Reichsführer-SS Heinrich Himmler from 1929, the SS had over a quarter million members by 1938.[233] Himmler initially envisioned the SS as being an elite group of guards, Hitler's last line of defence.[234] The Waffen-SS, the military branch of the SS, evolved into a second army. It was dependent on the regular army for heavy weaponry and equipment, and most units were under tactical control of the High Command of the Armed Forces (OKW).[235][236] By the end of 1942, the stringent selection and racial requirements that had initially been in place were no longer followed. With recruitment and conscription based only on expansion, by 1943 the Waffen-SS could not longer claim to be an elite fighting force.[237]
Women were encouraged to leave the workforce, and the creation of large families by racially suitable women was promoted through a propaganda campaign. Women received a bronze award—known as the Ehrenkreuz der Deutschen Mutter (Cross of Honour of the German Mother)—for giving birth to four children, silver for six, and gold for eight or more.[367] Large families received subsidies to help with expenses. Though the measures led to increases in the birth rate, the number of families having four or more children declined by five percent between 1935 and 1940.[370] Removing women from the workforce did not have the intended effect of freeing up jobs for men, as women were for the most part employed as domestic servants, weavers, or in the food and drink industries—jobs that were not of interest to men.[371] Nazi philosophy prevented large numbers of women from being hired to work in munitions factories in the build-up to the war, so foreign labourers were brought in. After the war started, slave labourers were extensively used.[372] In January 1943, Hitler signed a decree requiring all women under the age of fifty to report for work assignments to help the war effort.[373] Thereafter women were funnelled into agricultural and industrial jobs, and by September 1944 14.9 million women were working in munitions production.[374]
Those who reported for treatment in the infirmary had to line up in front of the infirmary barracks. After a prolonged waiting—often after hours—a doctor appeared and asked about the complaints. Thereupon he divided the prisoners into two categories: category one was examined and received into the sickroom if the occasion warranted it. In very grave cases—supposedly very rarely—inmates were taken to the police infirmary in Berlin. Category two was lined up without any sort of examination in front of the barracks, sometimes for hours, as a punishment, and then sent back to the barracks with the usual reprimands. The chief physician of the camp was called 'Dr. Cruel' by the old inmates. (His real name was Irrsam. 'Cruel' in German is grausam; the puns therefore, is not translatable.)

The NSDAP briefly adopted the designation "Nazi"[when?] in an attempt to reappropriate the term, but it soon gave up this effort and generally avoided using the term while it was in power.[10][11] For example, in Hitler's book Mein Kampf, originally published in 1925, he never refers to himself as a "Nazi."[15] A compendium of conversations of Hitler from 1941 through 1944 entitled Hitler's Table Talk does not contain the word "Nazi" either.[16] In speeches by Hermann Göring, he never uses the term "Nazi."[17] Hitler Youth leader Melita Maschmann wrote a book about her experience entitled Account Rendered[18]. She did not refer to herself as a "Nazi," even though she was writing well after World War II. In 1933 581 members of the National Socialist Party answered interview questions put to them by Professor Theodore Abel from Columbia University. They similarly did not refer to themselves as "Nazis."[19] In each case, the authors refer to themselves as "National Socialists" and their movement as "National Socialism," but never as "Nazis."
The first “bunker,” with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra “capacity” was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the “bunkers” were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open.
The Nazi regime promoted a liberal code of conduct regarding sexual matters and was sympathetic to women who bore children out of wedlock.[382] Promiscuity increased as the war progressed, with unmarried soldiers often intimately involved with several women simultaneously. Soldier's wives were frequently involved in extramarital relationships. Sex was sometimes used as a commodity to obtain better work from a foreign labourer.[383] Pamphlets enjoined German women to avoid sexual relations with foreign workers as a danger to their blood.[384]
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.

The reality of where we were, struck home fairly quickly. I was stationed near crematorium number four, and we witnessed the columns of unsuspecting women and children entering the gate of the crematorium; they would have been dead within half an hour. When the Hungarian Jews arrived they had the gas chambers going day and night. How can you wrap your imagination round that? I still can’t.
The Nazi Party Programme of 1920 guaranteed freedom for all religious denominations which were not hostile to the State and it also endorsed Positive Christianity in order to combat "the Jewish-materialist spirit".[207] Positive Christianity was a modified version of Christianity which emphasized racial purity and nationalism.[208] The Nazis were aided by theologians such as Ernst Bergmann. In his work Die 25 Thesen der Deutschreligion (Twenty-five Points of the German Religion), Bergmann held the view that the Old Testament of the Bible was inaccurate along with portions of the New Testament, claimed that Jesus was not a Jew but was instead of Aryan origin and he also claimed that Adolf Hitler was the new messiah.[208]
The Parteiflagge design, with the centred swastika disc, served as the party flag from 1920. Between 1933 (when the Nazi Party came to power) and 1935, it was used as the National flag (Nationalflagge) and Merchant flag (Handelsflagge), but interchangeably with the black-white-red horizontal tricolour. In 1935, the black-white-red horizontal tricolour was scrapped (again) and the flag with the off-centre swastika and disc was instituted as the national flag, and remained as such until 1945. The flag with the centred disk continued to be used after 1935, but exclusively as the Parteiflagge, the flag of the party.
Spengler's book The Decline of the West (1918), written during the final months of World War I, addressed the supposed decadence of modern European civilization, which he claimed was caused by atomising and irreligious individualisation and cosmopolitanism.[109] Spengler's major thesis was that a law of historical development of cultures existed involving a cycle of birth, maturity, ageing and death when it reaches its final form of civilisation.[109] Upon reaching the point of civilisation, a culture will lose its creative capacity and succumb to decadence until the emergence of "barbarians" creates a new epoch.[109] Spengler considered the Western world as having succumbed to decadence of intellect, money, cosmopolitan urban life, irreligious life, atomised individualisation and believed that it was at the end of its biological and "spiritual" fertility.[109] He believed that the "young" German nation as an imperial power would inherit the legacy of Ancient Rome, lead a restoration of value in "blood" and instinct, while the ideals of rationalism would be revealed as absurd.[109]

The Nazi Party grew significantly during 1921 and 1922, partly through Hitler's oratorical skills, partly through the SA's appeal to unemployed young men, and partly because there was a backlash against socialist and liberal politics in Bavaria as Germany's economic problems deepened and the weakness of the Weimar regime became apparent. The party recruited former World War I soldiers, to whom Hitler as a decorated frontline veteran could particularly appeal, as well as small businessmen and disaffected former members of rival parties. Nazi rallies were often held in beer halls, where downtrodden men could get free beer. The Hitler Youth was formed for the children of party members. The party also formed groups in other parts of Germany. Julius Streicher in Nuremberg was an early recruit and became editor of the racist magazine Der Stürmer. In December 1920, the Nazi Party had acquired a newspaper, the Völkischer Beobachter, of which its leading ideologist Alfred Rosenberg became editor. Others to join the party around this time were Heinrich Himmler and World War I flying ace Hermann Göring.
Probably my earliest memories of anything at all are of walking through the streets of Trenčín and people stopping in their tracks and saying with amazement: “You’re back!” “What a miracle that you’re alive!” I understood as a three-and-a-half to four-year-old that I was a miracle because I got to hear it so many times, but I didn’t really understand what the word meant. Only much later could I recognise what a miracle it really was that I had survived, when I learned that of the thousands of Slovak men and women who were deported to Auschwitz, only a few hundred returned.
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]
Eventually, Birkenau held the majority of prisoners in the Auschwitz complex, including Jews, Poles, Germans, and Gypsies. Furthermore, it maintained the most degrading and inhumane conditions–inclusive of the complex’s gas chambers and crematoria. A third section, Auschwitz III, was constructed in nearby Monowitz, and consisted of a forced labor camp called Buna-Monowitz.
We lived in Bótrágy, a very small, mostly poor town in Czechoslovakia with a population of approximately 1,000 mainly farming families, including about 10 Jewish families. The town was a typical low-income community with a tailor, a shoemaker, a grocery store, where people struggled to get by, but where everyone knew each other and there was easy communication between the neighbours, though that didn’t mean we were equal.
Of the Jews sent to Bergen-Belsen, very few were set free. One group of 222 Jews reached Palestine after leaving Bergen-Belsen on 10 July 1944. The second group left the camp in two parts – in August and December 1945, the Kasztner transport was sent to Switzerland. Finally, on 25 January 1945, 136 Jews with South American passports reached Switzerland.
There is no more forceful advocate for the preservation of Auschwitz than Wladyslaw Bartoszewski. Born in Warsaw in 1922, Bartoszewski, 87, was a Red Cross stretcher-bearer when the German Army invaded the capital city in September 1939. Plucked off the street by German soldiers a year later, he was sent to Auschwitz. He’d been there seven months when the Red Cross arranged for his release in April 1941—one of the few inmates ever set free.
Nazism rejected the Marxist concept of class conflict, and it praised both German capitalists and German workers as essential to the Volksgemeinschaft. In the Volksgemeinschaft, social classes would continue to exist, but there would be no class conflict between them.[170] Hitler said that "the capitalists have worked their way to the top through their capacity, and as the basis of this selection, which again only proves their higher race, they have a right to lead."[171] German business leaders co-operated with the Nazis during their rise to power and received substantial benefits from the Nazi state after it was established, including high profits and state-sanctioned monopolies and cartels.[172] Large celebrations and symbolism were used extensively to encourage those engaged in physical labour on behalf of Germany, with leading National Socialists often praising the "honour of labour", which fostered a sense of community (Gemeinschaft) for the German people and promoted solidarity towards the Nazi cause.[173] To win workers away from Marxism, Nazi propaganda sometimes presented its expansionist foreign policy goals as a "class struggle between nations."[171] Bonfires were made of school children's differently coloured caps as symbolic of the unity of different social classes.[174]

Other Nazis—especially those at the time associated with the party's more radical wing such as Gregor Strasser, Joseph Goebbels and Heinrich Himmler—rejected Italian Fascism, accusing it of being too conservative or capitalist.[126] Alfred Rosenberg condemned Italian Fascism for being racially confused and having influences from philosemitism.[127] Strasser criticised the policy of Führerprinzip as being created by Mussolini and considered its presence in Nazism as a foreign imported idea.[128] Throughout the relationship between Nazi Germany and Fascist Italy, a number of lower-ranking Nazis scornfully viewed fascism as a conservative movement that lacked a full revolutionary potential.[128]

In Mein Kampf, Hitler directly attacked both left-wing and right-wing politics in Germany.[75] However, a majority of scholars identify Nazism in practice as being a far-right form of politics.[76] When asked in an interview in 1934 whether the Nazis were "bourgeois right-wing" as alleged by their opponents, Hitler responded that Nazism was not exclusively for any class and indicated that it favoured neither the left nor the right, but preserved "pure" elements from both "camps" by stating: "From the camp of bourgeois tradition, it takes national resolve, and from the materialism of the Marxist dogma, living, creative Socialism".[77]
The trials began a public debate which in the 1990s led to explicit legislation against Holocaust denial in seven European countries. Around the time of Otto Frank’s death, Ditlieb Felderer, a Holocaust denier from Sweden, published an obscene pornographic pamphlet depicting Anne as a mature seductress and the diary as a pedophilic publication. Evidently Otto Frank never saw the pamphlet and did not manage to sue its writer. At the beginning of the 1990s the Anne Frank Trust, with the aid of other Dutch organizations, sued Faurisson and Verbeke. Finally, in 1998, after the diary underwent extensive technical and graphological examinations for the third time, an Amsterdam court found unequivocally for its authenticity and made denying it a criminal offense.
In most of the camps discovered by the Soviets, almost all the prisoners had already been removed, leaving only a few thousand alive—7,000 inmates were found in Auschwitz, including 180 children who had been experimented on by doctors.[45] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division,[46] 13,000 corpses lay unburied, and another 10,000 died from typhus or malnutrition over the following weeks.[47] The British forced the remaining SS guards to gather up the corpses and place them in mass graves.[48]
