On 1 September 1939, when Anne was 10 years old, Nazi Germany invaded Poland, and so the Second World War began. Not long after, on 10 May 1940, the Nazis also invaded the Netherlands. Five days later, the Dutch army surrendered. Slowly but surely, the Nazis introduced more and more laws and regulations that made the lives of Jews more difficult. For instance, Jews could no longer visit parks, cinemas, or non-Jewish shops. The rules meant that more and more places became off-limits to Anne. Her father lost his company, since Jews were no longer allowed to run their own businesses. All Jewish children, including Anne, had to go to separate Jewish schools.
The Nazis used propaganda to promulgate the concept of Rassenschande ("race defilement") to justify the need for racial laws.[214] In September 1935, the Nuremberg Laws were enacted. These laws initially prohibited sexual relations and marriages between Aryans and Jews and were later extended to include "Gypsies, Negroes or their bastard offspring".[215] The law also forbade the employment of German women under the age of 45 as domestic servants in Jewish households.[216] The Reich Citizenship Law stated that only those of "German or related blood" could be citizens.[217] Thus Jews and other non-Aryans were stripped of their German citizenship. The law also permitted the Nazis to deny citizenship to anyone who was not supportive enough of the regime.[217] A supplementary decree issued in November defined as Jewish anyone with three Jewish grandparents, or two grandparents if the Jewish faith was followed.[218]
Most of the teenage boys and girls in the photo are hamming it up for the camera, celebrating as nearly all raise as their right hand to deliver what looks like the Nazi salute. A few can be seen holding their phones and at least one girl appears to be taking a picture of the swastika made up of about 100 red plastic cups that look as though they've been set up to play a white supremacist version of the popular drinking game, beer pong.
T he use of gas chambers was the most common method of mass murdering the Jews in the extermination camps. The Jews were herded into the gas chambers, then the camp personnel closed the doors, and either exhaust gas (in Belzec, Sobibor and Treblinka) or poison gas in the form of Zyclon B or A (in Majdanek and Auschwitz-Birkenau) was led into the gas chamber.
The following summer, on June 5, 1934, Nazi lawyers, jurists, and medical doctors gathered under the auspices of Justice Minister Franz Gürtner to discuss how to codify the Prussian Memorandum. The very first item discussed was U.S. law: “Almost all the American states have race legislation,” Gürtner averred, before detailing a myriad of examples, including the many states that criminalized mixed marriages. Roland Freisler, the murderous Nazi judge, stated at the meeting that U.S. jurisprudence would “suit us perfectly.” All the participants displayed either an eager interest in, or an avowed knowledge of, U.S. law. This went beyond specific legislation. The Nazis looked to an innovative legal culture that found ways to relegate Native Americans, African Americans, immigrants, Chinese, Japanese, Filipinos, and others to second- and third-class status; the many devious pathways around the constitutional guarantees of equal protection; the deliberate textual ambiguity on the definition of race itself; the draconian penalties for sexually consorting with a lesser race, or even meeting publicly. The United States in the 1930s was the apogee of a racist state.
In early November 1944, Anne was put on transport again. Together with her sister, she was deported to the Bergen-Belsen concentration camp. Her parents stayed behind in Auschwitz. The conditions in Bergen-Belsen were horrible, too, there was a lack of food, it was cold, and Anne, like her sister, contracted typhus. In February 1945 they both died owing to its effects, Margot first, Anne shortly afterwards. 
There are only two possibilities in Germany; do not imagine that the people will forever go with the middle party, the party of compromises; one day it will turn to those who have most consistently foretold the coming ruin and have sought to dissociate themselves from it. And that party is either the Left: and then God help us! for it will lead us to complete destruction - to Bolshevism, or else it is a party of the Right which at the last, when the people is in utter despair, when it has lost all its spirit and has no longer any faith in anything, is determined for its part ruthlessly to seize the reins of power - that is the beginning of resistance of which I spoke a few minutes ago.[25]
The Nazis, the far-right monarchists, the reactionary German National People's Party (DNVP) and others, such as monarchist officers in the German Army and several prominent industrialists, formed an alliance in opposition to the Weimar Republic on 11 October 1931 in Bad Harzburg, officially known as the "National Front", but commonly referred to as the Harzburg Front.[30] The Nazis stated that the alliance was purely tactical and they continued to have differences with the DNVP. The Nazis described the DNVP as a bourgeois party and they called themselves an anti-bourgeois party.[30] After the elections of July 1932, the alliance broke down when the DNVP lost many of its seats in the Reichstag. The Nazis denounced them as "an insignificant heap of reactionaries".[31] The DNVP responded by denouncing the Nazis for their socialism, their street violence and the "economic experiments" that would take place if the Nazis ever rose to power.[32] But amidst an inconclusive political situation in which conservative politicians Franz von Papen and Kurt von Schleicher were unable to form stable governments without the Nazis, Papen proposed to President Hindenburg to appoint Hitler as Chancellor at the head of a government formed primarily of conservatives, with only three Nazi ministers.[33][34] Hindenburg did so, and contrary to the expectations of Papen and the DNVP, Hitler was soon able to establish a Nazi one-party dictatorship.[35]
The impulse to separate some groups of people from the category of the human is, however, a universal one. The enemies we kill in war, the convicted prisoners we lock up for life, even the distant workers who manufacture our clothes and toys—how could any society function if the full humanity of all these were taken into account? In a decent society, there are laws to resist such dehumanization, and institutional and moral forces to protest it. When guards at Rikers Island beat a prisoner to death, or when workers in China making iPhones begin to commit suicide out of despair, we regard these as intolerable evils that must be cured. It is when a society decides that some people deserve to be treated this way—that it is not just inevitable but right to deprive whole categories of people of their humanity—that a crime on the scale of the K.L. becomes a possibility. It is a crime that has been repeated too many times, in too many places, for us to dismiss it with the simple promise of never again. ♦
Large segments of the Nazi Party, particularly among the members of the Sturmabteilung (SA), were committed to the party's official socialist, revolutionary and anti-capitalist positions and expected both a social and an economic revolution when the party gained power in 1933.[43] In the period immediately before the Nazi seizure of power, there were even Social Democrats and Communists who switched sides and became known as "Beefsteak Nazis": brown on the outside and red inside.[44] The leader of the SA, Ernst Röhm, pushed for a "second revolution" (the "first revolution" being the Nazis' seizure of power) that would enact socialist policies. Furthermore, Röhm desired that the SA absorb the much smaller German Army into its ranks under his leadership.[43] Once the Nazis achieved power, Röhm's SA was directed by Hitler to violently suppress the parties of the left, but they also began attacks against individuals deemed to be associated with conservative reaction.[45] Hitler saw Röhm's independent actions as violating and possibly threatening his leadership, as well as jeopardising the regime by alienating the conservative President Paul von Hindenburg and the conservative-oriented German Army.[46] This resulted in Hitler purging Röhm and other radical members of the SA in 1934, in what came to be known as the Night of the Long Knives.[46]
When Soviet troops liberated Auschwitz on January 27, 1945, they found these pitiful survivors as well as 836,525 items of women clothing, 348,820 items of men clothing, 43,525 pairs of shoes and vast numbers of toothbrushes, glasses and other personal effects. They found also 460 artificial limbs and seven tons of human hair shaved from Jews before they were murdered. The human hairs were used by the company "Alex Zink" (located in Bavaria) for confection of cloth. This company was paying the human hairs 50 pfennig/kilo.
The first gassings at Auschwitz took place in early September 1941, when around 850 inmates—Soviet prisoners of war and sick Polish inmates—were killed with Zyklon B in the basement of block 11 in Auschwitz I. The building proved unsuitable, so gassings were conducted instead in crematorium I, also in at Auschwitz I, which operated until December 1942. There, more than 700 victims could be killed at once.[158] Tens of thousands were killed in crematorium I.[159] To keep the victims calm, they were told they were to undergo disinfection and de-lousing; they were ordered to undress outside, then were locked in the building and gassed. After its decommissioning as a gas chamber, the building was converted to a storage facility and later served as an SS air raid shelter.[160] The gas chamber and crematorium were reconstructed after the war. Dwork and van Pelt write that a chimney was recreated; four openings in the roof were installed to show where the Zyklon B had entered; and two of the three furnaces were rebuilt with the original components.[161]
In 1938, Otto Frank started a second company, Pectacon, which was a wholesaler of herbs, pickling salts, and mixed spices, used in the production of sausages.[11][12] Hermann van Pels was employed by Pectacon as an advisor about spices. A Jewish butcher, he had fled Osnabrück with his family.[12] In 1939, Edith Frank's mother came to live with the Franks, and remained with them until her death in January 1942.[13]

Historian Michael Burleigh claims that Nazism used Christianity for political purposes, but such use required that "fundamental tenets were stripped out, but the remaining diffuse religious emotionality had its uses".[215] Burleigh claims that Nazism's conception of spirituality was "self-consciously pagan and primitive".[215] However, historian Roger Griffin rejects the claim that Nazism was primarily pagan, noting that although there were some influential neo-paganists in the Nazi Party, such as Heinrich Himmler and Alfred Rosenberg, they represented a minority and their views did not influence Nazi ideology beyond its use for symbolism. It is noted that Hitler denounced Germanic paganism in Mein Kampf and condemned Rosenberg's and Himmler's paganism as "nonsense".[216]

Over the years, there have been dissenting views about the preservationist approach. “I’m not convinced about the current plans for Auschwitz,” said Jonathan Webber, a former member of the International Auschwitz Council of advisers, who teaches in the European Studies program at the Jagiellonian University in Krakow. “If you have a very good memorial, you could achieve that without having to have all this effort on conservation and restoration,” he added.
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]

When the Nazis came to power in Germany, they quickly moved to suppress all real and potential opposition. The general public was intimidated by the arbitrary psychological terror that was used by the special courts (Sondergerichte).[11] Especially during the first years of their existence when these courts "had a strong deterrent effect" against any form of political protest.[12]
