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.”
Nazism had peculiarly German roots. It can be partly traced to the Prussian tradition as developed under Frederick William I (1688–1740), Frederick the Great (1712–68), and Otto von Bismarck (1815–98), which regarded the militant spirit and the discipline of the Prussian army as the model for all individual and civic life. To it was added the tradition of political romanticism, with its sharp hostility to rationalism and to the principles underlying the French Revolution, its emphasis on instinct and the past, and its proclamation of the rights of Friedrich Nietzsche’s exceptional individual (the Übermensch [“Superman”]) over all universal law and rules. These two traditions were later reinforced by the 19th-century adoration of science and of the laws of nature, which seemed to operate independently of all concepts of good and evil. Further reinforcements came from such 19th-century intellectual figures as the comte de Gobineau (1816–82), Richard Wagner (1813–83), and Houston Stewart Chamberlain (1855–1927), all of whom greatly influenced early National Socialism with their claims of the racial and cultural superiority of the “Nordic” (Germanic) peoples over all other Europeans and all other races.
Hitler had the final say in both domestic legislation and German foreign policy. Nazi foreign policy was guided by the racist belief that Germany was biologically destined to expand eastward by military force and that an enlarged, racially superior German population should establish permanent rule in eastern Europe and the Soviet Union. Here, women played a vital role. The Third Reich's aggressive population policy encouraged "racially pure" women to bear as many "Aryan" children as possible.

Our daily occupation differed according to age. Prisoners below the forty-fifth year were used for especially hard labor outside the camp in the 'clinker works.' Heavy bags of cement had to be carried for long distances, and the return to the starting point had to be covered at a running pace. For a while the older prisoners were also used outside the camp working on an S.S. settlement. They had to dig or carry cement blocks. All this work was done under the supervision of young S.S. men, most of whom were boys of sixteen to twenty years from former Austria. They circled around us armed with loaded guns or light machine guns. They drove us on and misused their position of superiority with all sorts of torments. If presumably a little offense had been committed, especially if our speed of work didn't satisfy them, they might demand that the prisoner should do knee-bends until he was exhausted or that he roll down the slope a dozen times. In our camp were prisoners ranging in age from fourteen to eighty-four.
In the first months of Hitler's chancellorship, the Nazis instituted a policy of "coordination"—the alignment of individuals and institutions with Nazi goals. Culture, the economy, education, and law all came under Nazi control. The Nazi regime also attempted to "coordinate" the German churches and, although not entirely successful, won support from a majority of Catholic and Protestant clergymen.
During the 1920s, Hitler urged disparate Nazi factions to unite in opposition to Jewish Bolshevism.[251] Hitler asserted that the "three vices" of "Jewish Marxism" were democracy, pacifism and internationalism.[252] The Communist movement, the trade unions, the Social Democratic Party and the left-wing press were all considered to be Jewish-controlled and part of the "international Jewish conspiracy" to weaken the German nation by promoting internal disunity through class struggle.[53] The Nazis also believed that the Jews had instigated the Bolshevik revolution in Russia and that Communists had stabbed Germany in the back and caused it to lose the First World War.[253] They further argued that modern cultural trends of the 1920s (such as jazz music and cubist art) represented "cultural Bolshevism" and were part of a political assault aimed at the spiritual degeneration of the German Volk.[253] Joseph Goebbels published a pamphlet titled The Nazi-Sozi which gave brief points of how National Socialism differed from Marxism.[254] In 1930, Hitler said: "Our adopted term 'Socialist' has nothing to do with Marxist Socialism. Marxism is anti-property; true Socialism is not".[255]
Frank’s subsequent books and essays continued to win praise, if not popularity, earning her a reputation as a clear-eyed prophet carefully attuned to hypocrisy. Her readers will long remember the words she wrote in her diary at 15, included in the otherwise naive first section of "The House Behind": “I don’t believe that the big men are guilty of the war, oh no, the little man is just as guilty, otherwise the peoples of the world would have risen in revolt long ago! There’s in people simply an urge to destroy, an urge to kill, to murder and rage, and until all mankind without exception undergoes a great change, wars will be waged, everything that has been built up, cultivated and grown will be cut down and disfigured, and mankind will have to begin all over again.”
Whitman’s study covers the earliest period of the Nazi regime, before it arrived at its monstrous endpoint. The Nazis’ ideas were still being debated, discussed, and put into practice at this point. Since their beginnings on the fringes of German politics, the Nazis had advocated a program of racist nationalism; they were consumed by what Whitman calls Rassenwahn—“race madness.” It was this hysteria over race, and the single-minded focus on it, that distinguished Hitler and his party from other fascists and authoritarians. It was also why the Nazis looked to the United States for inspiration.
These guards were the core of what became, a few years later, the much feared Death’s-Head S.S. The name, along with the skull-and-crossbones insignia, was meant to reinforce the idea that the men who bore it were not mere prison guards but front-line soldiers in the Nazi war against enemies of the people. Himmler declared, “No other service is more devastating and strenuous for the troops than just that of guarding villains and criminals.” The ideology of combat had been part of the DNA of Nazism from its origin, as a movement of First World War veterans, through the years of street battles against Communists, which established the Party’s reputation for violence. Now, in the years before actual war came, the K.L. was imagined as the site of virtual combat—against Communists, criminals, dissidents, homosexuals, Jehovah’s Witnesses, and Jews, all forces working to undermine the German nation.
When the Nazis seized power in 1933, roughly 67 percent of the population of Germany was Protestant, 33 percent was Roman Catholic, while Jews made up less than 1 percent.[405][406] According to 1939 census, 54 percent considered themselves Protestant, 40 percent Roman Catholic, 3.5 percent Gottgläubig (God-believing; a Nazi religious movement) and 1.5 percent nonreligious.[407]
A concentration camp was not the same as an extermination camp – camps constructed with the specific purpose of mass murdering Jews and other victim groups. Despite this fact, the concentration camps claimed many thousands of victims. Imprisonment in a concentration camp meant inhuman forced labour, brutal mistreatment, hunger, disease, and random executions. It is certain that several hundred thousand died in the concentration camps. In comparison, more than three million Jews were murdered in the extermination camps.
I did go back to my home town, Radom, just once in 1996 or 1998. I saw our house, and stood in the backyard, but my heart was bleeding so much, I didn’t dare go in. I walked up the street and it was like walking on history – something lost and far away, but also very close. Here was the road on which I used to run to school, to the factory, but I had to get away very quickly. I was thinking: “I’m here, but where are all of them, my family?”
Memory is not something that is acquired once and stays on forever. The moment that the last eyewitnesses and survivors pass away, we have to work together to build on that which remains: the testimonies of those former prisoners and the authentic artifacts connected with Auschwitz. Each item can have its own enormous meaning and should find its place in the collection of the Auschwitz Memorial. Here, it will be preserved, studied, and displayed. Its place is here. 
That is why, since its creation in 2009, the foundation that raises money to maintain the site of Auschwitz-Birkenau has had a guiding philosophy: “To preserve authenticity.” The idea is to keep the place intact, exactly as it was when the Nazis retreated before the Soviet Army arrived in January 1945 to liberate the camp, an event that resonates on Holocaust Remembrance Day, on Thursday.
As a result of the Holocaust, the term "concentration camp" carries many of the connotations of "extermination camp" and is sometimes used synonymously. Because of these ominous connotations, the term "concentration camp", originally itself a euphemism, has been replaced by newer terms such as internment camp, resettlement camp, detention facility, etc., regardless of the actual circumstances of the camp, which can vary a great deal.
