When the Nazi Party emerged from obscurity to become a major political force after 1929, the conservative faction rapidly gained more influence, as wealthy donors took an interest in the Nazis as a potential bulwark against communism.[39] The Nazi Party had previously been financed almost entirely from membership dues, but after 1929 its leadership began actively seeking donations from German industrialists, and Hitler began holding dozens of fundraising meetings with business leaders.[40] In the midst of the Great Depression, facing the possibility of economic ruin on the one hand and a Communist or Social Democratic government on the other hand, German business increasingly turned to Nazism as offering a way out of the situation, by promising a state-driven economy that would support, rather than attack, existing business interests.[41] By January 1933, the Nazi Party had secured the support of important sectors of German industry, mainly among the steel and coal producers, the insurance business and the chemical industry.[42]
Auschwitz I, ul. Stanisławy Leszczyńskiej 11. The first camp to be used (called Stammlager by the Germans), consisting of old Polish Army barracks later converted into inmate housing, torture chambers, execution grounds, and SS administrative buildings. The infamous Arbeit macht frei gate is found here. Inside most of the barrack buildings are historical exhibits regarding the various nationalities held in the camp, video displays, photos, and personal belongings illustrating the life and cruelties of the Nazi terror. The only remaining gas chamber is found in Auschwitz I but note that, as indicated within the chamber, it was reconstructed to its wartime layout after the war.  edit
These public relations mishaps, clumsy though they may have been, were not really mistakes, nor even the fault of the museum alone. On the contrary, the runaway success of Anne Frank’s diary depended on playing down her Jewish identity: At least two direct references to Hanukkah were edited out of the diary when it was originally published. Concealment was central to the psychological legacy of Anne Frank’s parents and grandparents, German Jews for whom the price of admission to Western society was assimilation, hiding what made them different by accommodating and ingratiating themselves to the culture that had ultimately sought to destroy them. That price lies at the heart of Anne Frank’s endless appeal. After all, Anne Frank had to hide her identity so much that she was forced to spend two years in a closet rather than breathe in public. And that closet, hiding place for a dead Jewish girl, is what millions of visitors want to see.
I decided to go back to my village as I had nowhere else to go. But of the 1,000 or so of us who had been deported, only eight to 10 had survived. Some people had warned me not to go back, saying there had been attacks on those who had returned, including the Jewish woman I had worked for when I’d done my tailor apprenticeship. She’d gone back to reclaim some possessions she had left behind in somebody’s house and they killed her rather than return the items. She and her husband had been the only couple in Czemierniki to survive and then they went and murdered her when she came home.

The Allies received information about the murders from the Polish government-in-exile and Polish leadership in Warsaw, based mostly on intelligence from the Polish underground.[338][339] German citizens had access to information about what was happening, as soldiers returning from the occupied territories reported on what they had seen and done.[340] Historian Richard J. Evans states that most German citizens disapproved of the genocide.[341][h]

The Diary, which has been translated into more than 65 languages, is the most widely read diary of the Holocaust, and Anne is probably the best known of Holocaust victims. The Diary was also made into a play that premiered on Broadway in October 1955, and in 1956 it won both the Tony Award for best play and the Pulitzer Prize for best drama. A film version directed by George Stevens was produced in 1959. The play was controversial: it was challenged by screenwriter Meyer Levin, who wrote an early version of the play (later realized as a 35-minute radio play) and accused Otto Frank and his chosen screenwriters, Frances Goodrich and Albert Hackett, of sanitizing and de-Judaizing the story. The play was often performed in high schools throughout the world and was revived (with additions) on Broadway in 1997–98.

In June 1945 the Soviet authorities took over Auschwitz I and converted it into a POW camp for German prisoners. The hospital had to move beyond the camp perimeter into former administrative buildings, where it functioned until October 1945.[254] Many of the barracks at Birkenau were taken apart by civilians, who used the materials to rebuild their own homes, which had been levelled out in the construction of Auschwitz II. The poorest residents sifted the crematoria ashes in search of nuggets from melted gold, before warning shots were fired.[255] The POW camp for German prisoners of war was used until 1947 by the Soviet NKVD (People's Commissariat for Internal Affairs).[256] The NKVD and its Polish counterpart, the MBP, used the Auschwitz Neu-Dachs sub-camp at Jaworzno to the north of Oświęcim as a concentration camp from 1945 to 1956.[257] The Soviets dismantled and exported the IG Farben factories to the USSR.[258] Meanwhile, Soviet and Polish investigators worked to document the war crimes of the SS.[259] After the site became a museum in 1947, exhumation work lasted for more than a decade.[185]

The first experimental gassing took place in September 1941, when Lagerführer Karl Fritzsch, at the instruction of Rudolf Höss, killed a group of Soviet prisoners of war by throwing Zyklon B crystals into their basement cell in block 11 of Auschwitz I. A second group of 600 Soviet prisoners of war and around 250 sick Polish prisoners was gassed on 3–5 September.[29] The morgue was later converted to a gas chamber able to hold at least 700–800 people.[30] Zyklon B was dropped into the room through slits in the ceiling.[28] In the view of Filip Müller, one of the Sonderkommando who worked in crematorium I, tens of thousands of Jews were killed there from France, Holland, Slovakia, Upper Silesia, Yugoslavia, and from the Theresienstadt, Ciechanow, and Grodno ghettos.[31] The last inmates to be gassed in Auschwitz I, in December 1942, were 300–400 members of the Auschwitz II Sonderkommando, who had been forced to dig up that camp's mass graves, thought to hold 100,000 corpses, and burn the remains.[32]
The Nazis took things further, one step at the time. Jews had to start wearing a Star of David on their clothes and there were rumours that all Jews would have to leave the Netherlands. When Margot received a call-up to report for a so-called ‘labour camp’ in Nazi Germany on 5 July 1942, her parents were suspicious. They did not believe the call-up was about work and decided to go into hiding the next day in order to escape persecution.  
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.
German business leaders disliked Nazi ideology but came to support Hitler, because they saw the Nazis as a useful ally to promote their interests.[54] Business groups made significant financial contributions to the Nazi Party both before and after the Nazi seizure of power, in the hope that a Nazi dictatorship would eliminate the organized labour movement and the left-wing parties.[55] Hitler actively sought to gain the support of business leaders by arguing that private enterprise is incompatible with democracy.[56]

By early 1934, the focus shifted towards rearmament. By 1935, military expenditures accounted for 73 percent of the government's purchases of goods and services.[267] On 18 October 1936, Hitler named Göring as Plenipotentiary of the Four Year Plan, intended to speed up rearmament.[268] In addition to calling for the rapid construction of steel mills, synthetic rubber plants, and other factories, Göring instituted wage and price controls and restricted the issuance of stock dividends.[251] Large expenditures were made on rearmament in spite of growing deficits.[269] Plans unveiled in late 1938 for massive increases to the navy and air force were impossible to fulfil, as Germany lacked the finances and material resources to build the planned units, as well as the necessary fuel required to keep them running.[270] With the introduction of compulsory military service in 1935, the Reichswehr, which had been limited to 100,000 by the terms of the Versailles Treaty, expanded to 750,000 on active service at the start of World War II, with a million more in the reserve.[271] By January 1939, unemployment was down to 301,800 and it dropped to only 77,500 by September.[272]
^ Scholarship for Martin Luther's 1543 treatise, On the Jews and their Lies, exercising influence on Germany's attitude: * Wallmann, Johannes. "The Reception of Luther's Writings on the Jews from the Reformation to the End of the 19th Century", Lutheran Quarterly, n.s. 1 (Spring 1987) 1:72–97. Wallmann writes: "The assertion that Luther's expressions of anti-Jewish sentiment have been of major and persistent influence in the centuries after the Reformation, and that there exists a continuity between Protestant anti-Judaism and modern racially oriented anti-Semitism, is at present wide-spread in the literature; since the Second World War it has understandably become the prevailing opinion." * Michael, Robert. Holy Hatred: Christianity, Antisemitism, and the Holocaust. New York: Palgrave Macmillan, 2006; see chapter 4 "The Germanies from Luther to Hitler", pp. 105–151. * Hillerbrand, Hans J. "Martin Luther," Encyclopædia Britannica, 2007. Hillerbrand writes: "[H]is strident pronouncements against the Jews, especially toward the end of his life, have raised the question of whether Luther significantly encouraged the development of German anti-Semitism. Although many scholars have taken this view, this perspective puts far too much emphasis on Luther and not enough on the larger peculiarities of German history."

The conservators have an easy camaraderie, but sometimes their task can become too much to bear. “Working with shoes probably is one of the most difficult parts of working here,” Ms. Banas-Maciaszczyk said. Everyone here has emotional moments. For her, it was a day when she was cleaning a little girl’s wooden sandal. She could see the small footprint inside. “This is something hard to describe,” she said. From 1940 to 1945, between 150,000 and 200,000 children died here.
One exchange Jew was Eve, daughter of Hans and Rita Oppenheimer. The family was German–Jewish. Eve’s father had moved to Holland from Germany to escape Nazi persecution. Eve was born in June 1936 during a visit to England by her mother and brothers, Paul and Rudi; she therefore had British nationality. The mother, brothers and sister then joined the father in Holland.
Oswald Spengler, a German cultural philosopher, was a major influence on Nazism, although after 1933 he became alienated from Nazism and was later condemned by the Nazis for criticising Adolf Hitler.[109] Spengler's conception of national socialism and a number of his political views were shared by the Nazis and the Conservative Revolutionary movement.[110] Spengler's views were also popular amongst Italian Fascists, including Benito Mussolini.[111]
After the failure of the Beer Hall Putsch in 1923, and his subsequent trial and imprisonment, Hitler decided that the way for the Nazi Party to achieve power was not through insurrection, but through legal and quasi-legal means. This did not sit well with the brown-shirted stormtroopers of the SA, especially those in Berlin, who chafed under the restrictions that Hitler placed on them, and their subordination to the party. This resulted in the Stennes Revolt of 1930-31, after which Hitler made himself the Supreme Commander of the SA, and brought Ernst Röhm back to be their Chief of Staff and keep them in line. The quashing of the SA's revolutionary fervor convinced many businessmen and military leaders that the Nazis had put aside their insurrectionist past, and that Hitler could be a reliable partner [279][280]
Besides tormenting us physically, the S. S. guard continually tried to torment us morally. Coming partly from the lowest proletariat, they tried to annoy us with quotations from the Stürmer. They asked us about the accuracy of supposed quotations from the Talmud which are purported to order the Jew to hate other nations, and especially all Christians. They had little success with these questions, since the prisoners had to answer almost without exception that they did not know more than the name of the Talmud.

After September 1939, with the beginning of the Second World War, concentration camps became places where millions of ordinary people were enslaved as part of the war effort, often starved, tortured and killed.[21] During the war, new Nazi concentration camps for "undesirables" spread throughout the continent. According to statistics by the German Ministry of Justice, about 1,200 camps and subcamps were run in countries occupied by Nazi Germany,[22] while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe[23][24] and that many of these camps were run for a limited amount of time before they were closed.[23] Camps were being created near the centers of dense populations, often focusing on areas with large communities of Jews, Polish intelligentsia, Communists or Romani. Since millions of Jews lived in pre-war Poland, most camps were located in the area of the General Government in occupied Poland, for logistical reasons. The location also allowed the Nazis to quickly remove the German Jews from within Germany proper.
