Notions of white supremacy and Aryan racial superiority were combined in the 19th century, with white supremacists maintaining the belief that certain groups of white people were members of an Aryan "master race" that is superior to other races and particularly superior to the Semitic race, which they associated with "cultural sterility".[80] Arthur de Gobineau, a French racial theorist and aristocrat, blamed the fall of the ancien régime in France on racial degeneracy caused by racial intermixing, which he argued had destroyed the purity of the Aryan race, a term which he only reserved for Germanic people.[81][82] Gobineau's theories, which attracted a strong following in Germany,[81] emphasized the existence of an irreconcilable polarity between Aryan (Germanic) and Jewish cultures.[80]
After the outbreak of war, people from across Europe were deported to Mauthausen, which gradually developed into a system of several interconnected camps. During this phase, Mauthausen and Gusen were the concentration camps with the harshest imprisonment conditions and the highest mortality. Prisoners at the bottom of the camp hierarchy had barely any chance of surviving for long. Those who were ill or ‘useless’ to the SS were in constant danger of their lives. In 1941 the SS started to construct a gas chamber and other installations at Mauthausen for the systematic murder of large groups of people.
On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households.[12] The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship.[13] By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.[14][15]

I had trained as a tailor and had left home before we were deported, when I went to work four miles away on a ranch. It was taken over by the SS, so suddenly I found myself working for them. In May 1943 they lined us up one day and told us to empty our pockets. If they found even a single zloty in anyone’s pocket, they were shot on the spot. We were transported to Majdanek, which was only 19 miles away – a torture camp in the true sense of the word. For 500 metres there were just ditches full of bodies, legs, heads. We were deported to Auschwitz four weeks later. We arrived in the early morning and they gave us a bed, a real shower, they cleaned us well with disinfectant and shaved us. After that they gave us striped uniforms and tattooed us. I was given the number 128164 on my left arm and from that point on I was a number, no longer a name.

Nazis constructed gas chambers (rooms that filled with poison gas to kill those inside) to increase killing efficiency and to make the process more impersonal for the perpetrators. At the Auschwitz camp complex, the Birkenau killing center had four gas chambers. During the height of deportations to the camp in 1943-44, an average of 6,000 Jews were gassed there each day.
Under the Gleichschaltung process, Hitler attempted to create a unified Protestant Reich Church from Germany's 28 existing Protestant state churches,[408] with the ultimate goal of eradication of the churches in Germany.[409] Pro-Nazi Ludwig Müller was installed as Reich Bishop and the pro-Nazi pressure group German Christians gained control of the new church.[410] They objected to the Old Testament because of its Jewish origins and demanded that converted Jews be barred from their church.[411] Pastor Martin Niemöller responded with the formation of the Confessing Church, from which some clergymen opposed the Nazi regime.[412] When in 1935 the Confessing Church synod protested the Nazi policy on religion, 700 of their pastors were arrested.[413] Müller resigned and Hitler appointed Hanns Kerrl as Minister for Church Affairs to continue efforts to control Protestantism.[414] In 1936, a Confessing Church envoy protested to Hitler against the religious persecutions and human rights abuses.[413] Hundreds more pastors were arrested.[414] The church continued to resist and by early 1937 Hitler abandoned his hope of uniting the Protestant churches.[413] Niemöller was arrested on 1 July 1937 and spent most of the next seven years in Sachsenhausen concentration camp and Dachau.[415] Theological universities were closed and pastors and theologians of other Protestant denominations were also arrested.[413]
Otto Frank survived his internment in Auschwitz. After the war ended, he returned to Amsterdam, where he was sheltered by Jan and Miep Gies as he attempted to locate his family. He learned of the death of his wife, Edith, in Auschwitz, but remained hopeful that his daughters had survived. After several weeks, he discovered Margot and Anne had also died. He attempted to determine the fates of his daughters' friends and learned many had been murdered. Sanne Ledermann, often mentioned in Anne's diary, had been gassed along with her parents; her sister, Barbara, a close friend of Margot's, had survived.[63] Several of the Frank sisters' school friends had survived, as had the extended families of Otto and Edith Frank, as they had fled Germany during the mid-1930s, with individual family members settling in Switzerland, the United Kingdom, and the United States.[64]
After his daughter’s writings were returned to him, Otto Frank helped compile them into a manuscript that was published in the Netherlands in 1947 under the title “Het Acheterhuis” (“Rear Annex”). Although U.S. publishers initially rejected the work as too depressing and dull, it was eventually published in America in 1952 as “The Diary of a Young Girl.” The book, which went on to sell tens of millions of copies worldwide, has been labeled a testament to the indestructible nature of the human spirit. It is required reading at schools around the globe and has been adapted for the stage and screen.
Despite such tactical breaks necessitated by pragmatic concerns, which were typical for Hitler during his rise to power and in the early years of his regime, Hitler never ceased being a revolutionary dedicated to the radical transformation of Germany, especially when it concerned racial matters. In his monograph, Hitler: Study of a Revolutionary?, Martyn Housden concludes:
Influenced by the Völkisch movement, the regime was against cultural modernism and supported the development of an extensive military at the expense of intellectualism.[8][187] Creativity and art were stifled, except where they could serve as propaganda media.[188] The party used symbols such as the Blood Flag and rituals such as the Nazi Party rallies to foster unity and bolster the regime's popularity.[189]

Early in the Nazi regime of Adolf Hitler, Anne’s father, Otto Frank (1889–1980), a German businessman, took his wife and two daughters to live in Amsterdam. In 1941, after German forces occupied the Netherlands, Anne was compelled to transfer from a public school to a Jewish one. On June 12, 1942, she received a red-and-white plaid diary for her 13th birthday. That day she began writing in the book: “I hope I will be able to confide everything to you, as I have never been able to confide in anyone, and I hope you will be a great source of comfort and support.”
The two largest groups of prisoners in the camps, both numbering in the millions, were the Polish Jews and the Soviet prisoners of war (POWs) held without trial or judicial process. There were also large numbers of Romani people, ethnic Poles, Serbs, political prisoners, homosexuals, people with disabilities, Jehovah's Witnesses, Catholic clergy, Eastern European intellectuals and others (including common criminals, as the Nazis declared). In addition, a small number of Western Allied aviators were sent to concentration camps as punishment for spying.[28] Western Allied POWs who were Jews, or who were suspected of being Jews by the Nazis, were usually sent to ordinary POW camps; however, a small number of them were sent to concentration camps because of antisemitic policies.[29]
