In July 1945, after the Red Cross confirmed the deaths of the Frank sisters, Miep Gies gave Otto Frank the diary and a bundle of loose notes that she had saved in the hope of returning them to Anne. Otto Frank later commented that he had not realized Anne had kept such an accurate and well-written record of their time in hiding. In his memoir, he described the painful process of reading the diary, recognizing the events described and recalling that he had already heard some of the more amusing episodes read aloud by his daughter. He saw for the first time the more private side of his daughter and those sections of the diary she had not discussed with anyone, noting, "For me it was a revelation ... I had no idea of the depth of her thoughts and feelings ... She had kept all these feelings to herself".[65] Moved by her repeated wish to be an author, he began to consider having it published.[66]
Upon arrival at Auschwitz, the SS forcibly separated the men from the women and children, and Otto Frank was wrenched from his family. Those deemed able to work were admitted into the camp, and those deemed unfit for labour were immediately killed. Of the 1,019 passengers, 549—including all children younger than 15—were sent directly to the gas chambers. Anne Frank, who had turned 15 three months earlier, was one of the youngest people spared from her transport. She was soon made aware that most people were gassed upon arrival and never learned that the entire group from the Achterhuis had survived this selection. She reasoned that her father, in his mid-fifties and not particularly robust, had been killed immediately after they were separated.[52]
From 1921 to 1922, Hitler evoked rhetoric of both the achievement of Lebensraum involving the acceptance of a territorially reduced Russia as well as supporting Russian nationals in overthrowing the Bolshevik government and establishing a new Russian government.[131] Hitler's attitudes changed by the end of 1922, in which he then supported an alliance of Germany with Britain to destroy Russia.[131] Hitler later declared how far he intended to expand Germany into Russia:
Today, at the beginning of the twenty-first century, the diary has not lost its power: in 2002, Habimah staged the play for the sixth time in Israel, an average of once per decade. In March 2002, Carol Ann Lee’s biography of Otto Frank, The Hidden Life of Otto Frank, had the Netherlands in an uproar. She places responsibility for the discovery of the attic’s inhabitants on Anton (Tony) Ahlers, a sworn antisemite and a member of the Dutch Nazi party who systematically informed on Jews. Ahlers was Frank’s business partner and knew that his spice company had done business with the Wehrmacht at the beginning of the war. Frank evidently paid Ahlers hush money even before his family entered the attic. Afterwards, he paid him not to reveal to the Dutch government that he had done business with the Wehrmacht, and apparently continued to pay him off until his death in 1980. Following the public furor, which spread to the United States, The Netherlands State Institute for War Documentation, the main organization that researches Anne Frank’s legacy today, announced that it would investigate Lee’s claims and soon publish its findings. Lee’s biography turns Anne’s father, the man who influenced her more than anyone and won her total admiration, into a man of flesh and blood devoid of the saintly image that had previously clung to him. It also placed the issues of informing and collaboration in the Netherlands and in Europe back on the public agenda, along with the question of the relationship to the Jewish citizens of those countries and their fate. Once more, Anne’s image hovers over the controversy, with its dark eyes and penetrating gaze, its hopes for a new world and faith in humankind.
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.
In the Holocaust, millions of Jews, as well as Roma people (also called "Gypsies"), people with disabilities, homosexuals, political opponents, and many other people were sent to concentration camps and death camps in Poland and Germany. The Nazis killed millions of these people at the concentration camps with poison gas. The Nazis also killed millions of people in these groups by forcing them to do slave labor without giving them much food or clothing. In total, 17 million people died- 6 million of them Jews.
During June and July 1933, all competing parties were either outlawed or dissolved themselves and subsequently the Law against the founding of new parties of 14 July 1933 legally established the Nazi Party's monopoly. On 1 December 1933, the Law to secure the unity of party and state entered into force, which was the base for a progressive intertwining of party structures and state apparatus.[82] By this law, the SA—actually a party division—was given quasi-governmental authority and their leader was co-opted as an ex officio cabinet member. By virtue of a 30 January 1934 Law concerning the reorganisation of the Reich, the Länder (states) lost their statehood and were demoted to administrative divisions of the Reich's government (Gleichschaltung). Effectively, they lost most of their power to the Gaue that were originally just regional divisions of the party, but took over most competencies of the state administration in their respective sectors.[83]

On July 15, 1944, three weeks before the hiding place where she lived with her family and several others was discovered, Anne Frank wrote in her diary: “It’s a wonder I haven’t abandoned all my ideals, they seem so absurd and impractical. Yet I cling to them because I still believe, in spite of everything, that people are truly good at heart.” Anne Frank’s diary, particularly these sentences, became one of the central symbols of the Holocaust and of humanity faced with suffering: the strength of spirit that led a young girl to write such words after two years of imprisonment hidden in a small, crowded attic, decreed on her by senseless evil; and the opening which her words offer for a new era of hope and reconciliation after a world war that claimed tens of millions of victims. These words aroused great admiration for her diary and for the girl herself. Translated into more than fifty languages, the diary sold more than thirty million copies all over the world. Streets and squares, coins and stamps bear Anne’s name, along with prizes, conventions, exhibits, memorials, schools and youth institutions, to say nothing of films and plays that bring her diary to life, and thorough research of various kinds into her character and her diary, its translations and the different uses that have been made and still are being made of it.
Auschwitz originally was conceived as a concentration camp, to be used as a detention center for the many Polish citizens arrested after Germany annexed the country in 1939. These detainees included anti-Nazi activists, politicians, resistance members and luminaries from the cultural and scientific communities. Once Hitler’s Final Solution became official Nazi policy, however, Auschwitz was deemed an ideal death camp locale. For one thing, it was situated near the center of all German-occupied countries on the European continent. For another, it was in close proximity to the string of rail lines used to transport detainees to the network of Nazi camps.
In April 1940, Rudolph Höss, who become the first commandant, identified the Silesian town of Oswiecim as a possible site for a concentration camp. The function of the camp was initially to intimidate Poles and prevent resistance to German rule. It was also perceived as a cornerstone of the policy to re-colonize Upper Silesia, which had once been a German region, with 'pure Aryans'. On April 27th, Himmler ordered construction of the camp.
The Auschwitz I main camp was a place of extermination, effected mainly by depriving people of elementary living conditions. It was also a centre for immediate extermination. Here were located the offices of the camp’s administration, the local garrison commander and the commandant of Auschwitz I, the seat of the central offices of the political department, and the prisoner labour department. Here too were the main supply stores, workshops and Schutzstaffel (SS) companies. Work in these administrative and economic units and companies was the main form of forced labour for the inmates in this camp.
A total of 22 main concentration camps (Stamlager) were established, together with approximately 1,200 affiliate camps. Besides these, thousands of smaller camps existed in all parts of German-controlled Europe. The 22 main camps, in alphabetical order, were as follows: Arbeitsdorf, Auschwitz, Bergen-Belsen, Buchenwald, Dachau, Flossenbürg, Gross-Rosen, Herzogenbosch, Kaunas, Krakow-Plaszow, Majdanek, Mauthausen, Mittelbau-Dora, Natzweiler-Struthof, Neuengamme, Ravensbrück, Riga-Kaiserwald, Sachsenhausen, Stutthof, Vaivara, Warsaw, Wewelsburg, Germany.

Although Nazism is often seen as a reactionary movement, it did not seek a return of Germany to the pre-Weimar monarchy, but instead looked much further back to a mythic halcyon Germany which never existed. It has also been seen – as it was by the German-American scholar Franz Leopold Neumann – as the result of a crisis of capitalism which manifested as a "totalitarian monopoly capitalism". In this view Nazism is a mass movement of the middle class which was in opposition to a mass movement of workers in socialism and its extreme form, Communism.[277] Historian Karl Dietrich Bracher, however, argues that,
In addition to eliminating Jews, the Nazis planned to reduce the population of the conquered territories by 30 million people through starvation in an action called the Hunger Plan. Food supplies would be diverted to the German army and German civilians. Cities would be razed and the land allowed to return to forest or resettled by German colonists.[327] Together, the Hunger Plan and Generalplan Ost would have led to the starvation of 80 million people in the Soviet Union.[328] These partially fulfilled plans resulted in the democidal deaths of an estimated 19.3 million civilians and prisoners of war (POWs).[329] During the course of the war, the Soviet Union lost a total of 27 million people; less than nine million of these were combat deaths.[330] One in four of the Soviet population were killed or wounded.[331]
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.
