Adolf Hitler was released from prison on 20 December 1924. On 16 February 1925, Hitler convinced the Bavarian authorities to lift the ban on the NSDAP and the party was formally refounded on 26 February 1925, with Hitler as its undisputed leader. The new Nazi Party was no longer a paramilitary organisation and disavowed any intention of taking power by force. In any case, the economic and political situation had stabilised and the extremist upsurge of 1923 had faded, so there was no prospect of further revolutionary adventures. The Nazi Party of 1925 was divided into the "Leadership Corps" (Korps der politischen Leiter) appointed by Hitler and the general membership (Parteimitglieder). The party and the SA were kept separate and the legal aspect of the party's work was emphasised. In a sign of this, the party began to admit women. The SA and the SS members (the latter founded in 1925 as Hitler's bodyguard, and known originally as the Schutzkommando) had to all be regular party members.[68][69]
After the war, the Allies occupied Germany, outlawed the Nazi Party and worked to purge its influence from every aspect of German life. The party’s swastika flag quickly became a symbol of evil in modern postwar culture. Although Hitler killed himself before he could be brought to justice, a number of Nazi officials were convicted of war crimes in the Nuremberg trials, which took place in Nuremberg, Germany, from 1945 to 1949.
And if existence was a struggle, a war, then it made no sense to show mercy to the enemy. Like many Nazi institutions, the K.L. embodied conflicting impulses: to reform the criminal, to extort labor from the unproductive, to quarantine the contagious. But most fundamental was the impulse to dehumanize the enemy, which ended up confounding and overriding all the others. Once a prisoner ceased to be human, he could be brutalized, enslaved, experimented on, or gassed at will, because he was no longer a being with a soul or a self but a biological machine. The Muselmänner, the living dead of the camps, stripped of any capacity to think or feel, were the true product of the K.L., the ultimate expression of the Nazi world view.
A neighbor and acquaintance of the Frank girls later said that Anne was extremely talented but also harsh, rebellious and sharp-tongued, while her parents were easygoing people and Margot was an excellent and much-liked pupil. Yet the diary shows the world a sensitive and talented Anne while depicting her mother and sister as self-righteous complainers. Another childhood friend of Anne’s gave similar accounts of the family’s personalities, describing Anne as acquisitive, self-centered and very sexual. A series of accounts, interviews and biographies that appeared mainly in the 1980s and 1990s describe Anne and the other fugitives in a more complex manner than the diary and its successors.
From the mid- to late 1930s, Hitler undermined the postwar international order step by step. He withdrew Germany from the League of Nations in 1933, rebuilt German armed forces beyond what was permitted by the Treaty of Versailles, reoccupied the German Rhineland in 1936, annexed Austria in 1938 and invaded Czechoslovakia in 1939. When Nazi Germany moved toward Poland, Great Britain and France countered further aggression by guaranteeing Polish security. Nevertheless, Germany invaded Poland on September 1, 1939, and Great Britain and France declared war on Germany. Six years of Nazi Party foreign policy had ignited World War II.
On 28 October, selections began for women to be relocated to Bergen-Belsen. More than 8,000 women, including Anne and Margot Frank, and Auguste van Pels, were transported. Edith Frank was left behind and died from starvation.[54] Tents were erected at Bergen-Belsen to accommodate the influx of prisoners, and as the population rose, the death toll due to disease increased rapidly. Frank was briefly reunited with two friends, Hanneli Goslar and Nanette Blitz, who were confined in another section of the camp. Goslar and Blitz survived the war, and discussed the brief conversations they had conducted with Frank through a fence. Blitz described Anne as bald, emaciated, and shivering. Goslar noted Auguste van Pels was with Anne and Margot Frank, and was caring for Margot, who was severely ill. Neither of them saw Margot, as she was too weak to leave her bunk. Anne told Blitz and Goslar she believed her parents were dead, and for that reason she did not wish to live any longer. Goslar later estimated their meetings had taken place in late January or early February 1945.[55]
At this time only the main camp, later known as Auschwitz I, had been established. Himmler ordered the construction of a second camp for 100,000 inmates on the site of the village of Brzezinka, roughly two miles from the main camp. This second camp, now known as Birkenau or Auschwitz II, was initially intended to be filled with captured Russian POWs who would provide the slave labor to build the SS “utopia” in Upper Silesia. Chemical giant I G Farben expressed an interest in utilizing this labor force, and extensive construction work began in October 1941 under terrible conditions and with massive loss of life. About 10,000 Russian POWs died in this process. The greater part of the apparatus of mass extermination was eventually built in the Birkenau camp and the majority of the victims were murdered here.
After examining several sites for a new plant to manufacture Buna-N, a type of synthetic rubber essential to the war effort, the German chemical cartel IG Farben chose a site near the towns of Dwory and Monowice (Monowitz in German), about 7 kilometres (4.3 mi) east of Auschwitz I.[50] Tax exemptions were available to corporations prepared to develop industries in the frontier regions under the Eastern Fiscal Assistance Law, passed in December 1940. The site had good railway connections and access to raw materials.[51] In February 1941, Himmler ordered that the Jewish population of Oświęcim be expelled to make way for skilled laborers; that all Poles able to work remain in the town and work on building the factory; and that Auschwitz prisoners be used in the construction work.[52]
Disfigured by a brutal beating, Frank rarely granted interviews; her later work, "The Return," describes how her father did not recognize her upon their reunion in 1945. "The House Behind" was searing and accusatory: The family’s initial hiding place, mundane and literal in the first section, is revealed in the second part to be a metaphor for European civilization, whose facade of high culture concealed a demonic evil. “Every flat, every house, every office building in every city,” she wrote, “they all have a House Behind.” The book drew respectful reviews, but sold few copies.
The party's nominal Deputy Leader was Rudolf Hess, but he had no real power in the party. By the early 1930s, the senior leaders of the party after Hitler were Heinrich Himmler, Joseph Goebbels and Hermann Göring. Beneath the Leadership Corps were the party's regional leaders, the Gauleiters, each of whom commanded the party in his Gau ("region"). Goebbels began his ascent through the party hierarchy as Gauleiter of Berlin-Brandenburg in 1926. Streicher was Gauleiter of Franconia, where he published his antisemitic newspaper Der Stürmer. Beneath the Gauleiter were lower-level officials, the Kreisleiter ("county leaders"), Zellenleiter ("cell leaders") and Blockleiter ("block leaders"). This was a strictly hierarchical structure in which orders flowed from the top and unquestioning loyalty was given to superiors. Only the SA retained some autonomy. Being composed largely of unemployed workers, many SA men took the Nazis' socialist rhetoric seriously. At this time, the Hitler salute (borrowed from the Italian fascists) and the greeting "Heil Hitler!" were adopted throughout the party.
After their arrest, the Franks, Van Pels and Fritz Pfeffer were sent by the Gestapo to Westerbork, a holding camp in the northern Netherlands. From there, in September 1944, the group was transported by freight train to the Auschwitz-Birkenau extermination and concentration camp complex in German-occupied Poland. Anne and Margot Frank were spared immediate death in the Auschwitz gas chambers and instead were sent to Bergen-Belsen, a concentration camp in northern Germany. In March 1945, the Frank sisters died of typhus at Bergen-Belsen; their bodies were thrown into a mass grave. Several weeks later, on April 15, 1945, British forces liberated the camp.

On 13 July 1942, the Franks were joined by the van Pels, made up of Hermann, Auguste, and 16-year-old Peter, and then in November by Fritz Pfeffer, a dentist and friend of the family. Frank wrote of her pleasure at having new people to talk to, but tensions quickly developed within the group forced to live in such confined conditions. After sharing her room with Pfeffer, she found him to be insufferable and resented his intrusion,[26] and she clashed with Auguste van Pels, whom she regarded as foolish. She regarded Hermann van Pels and Fritz Pfeffer as selfish, particularly in regard to the amount of food they consumed.[27] Some time later, after first dismissing the shy and awkward Peter van Pels, she recognized a kinship with him and the two entered a romance. She received her first kiss from him, but her infatuation with him began to wane as she questioned whether her feelings for him were genuine, or resulted from their shared confinement.[28] Anne Frank formed a close bond with each of the helpers, and Otto Frank later recalled that she had anticipated their daily visits with impatient enthusiasm. He observed that Anne's closest friendship was with Bep Voskuijl, "the young typist ... the two of them often stood whispering in the corner."[29]
I do not understand, however, the attitude of Hitler and his followers in this matter. To atone for the Paris murder, the Nazis imposed a collective punishment upon all German subjects of Jewish origin. First they organized a 'spontaneous' outburst of popular rage on the eve of November 10, 1938, throughout Germany at almost the same hour, and everywhere by the same methods. Abuses and tortures, even manslaughter, destruction of Jewish shops and apartments, arson of synagogues with gasoline brought for the purpose—such was the program.
Another important figure in pre-Nazi völkisch thinking was Wilhelm Heinrich Riehl, whose work—Land und Leute (Land and People, written between 1857 and 1863)—collectively tied the organic German Volk to its native landscape and nature, a pairing which stood in stark opposition to the mechanical and materialistic civilization which was then developing as a result of industrialization.[63] Geographers Friedrich Ratzel and Karl Haushofer borrowed from Riehl's work as did Nazi ideologues Alfred Rosenberg and Paul Schultze-Naumburg, both of whom employed some of Riehl's philosophy in arguing that "each nation-state was an organism that required a particular living space in order to survive".[64] Riehl's influence is overtly discernible in the Blut und Boden (Blood and Soil) philosophy introduced by Oswald Spengler, which the Nazi agriculturalist Walther Darré and other prominent Nazis adopted.[65][66]
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]
The Nazis’ goal wasn’t only to destroy evidence of the camp: They had plans to force the prisoners to serve as slave laborers for the Reich. Some prisoners were stuffed into train cars to complete their journey to Germany; others escaped into the sub-zero temperatures. Of those forced to walk, some died along the way, though it remains unclear how many were killed over the course of the marches.
All of the extermination camps were thoroughly organised and resembled industrial plants to an alarming degree. However, only Auschwitz-Birkenau, with its advanced gassing facilities and crematoria, was marked by high technology. In crematoria I and II there were elevators from the gas chambers underground, where the Jews were murdered, to the crematoria, where the bodies were burned.
Several SS personnel oversaw the killings at each gas chamber, while the bulk of the work was done by the mostly Jewish prisoners known as Sonderkommandos (special squads).[91][92] Hungarian doctor Miklós Nyiszli reported that the Sonderkommando numbered around 860 prisoners when the Hungarian Jews were being killed in May–July 1944.[93] Their responsibilities included removing goods and corpses from the incoming trains, guiding victims to the dressing rooms and gas chambers, and working in the "Canada" barracks, where the victims' possessions were stored.[94] Housed separately from other prisoners, in somewhat better conditions, their quality of life was further improved by access to the goods taken from murdered prisoners, which they were sometimes able to steal and trade on Auschwitz's black market.[95] Many Sonderkommandos committed suicide in response to the horrors of their work; others were generally shot by the SS in a matter of weeks. New Sonderkommando units were formed from incoming transports. Almost none of the 2,000 prisoners placed in these units survived to the camp's liberation.[96]
In most of the camps discovered by the Soviets, almost all the prisoners had already been removed, leaving only a few thousand alive—7,000 inmates were found in Auschwitz, including 180 children who had been experimented on by doctors.[45] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division,[46] 13,000 corpses lay unburied, and another 10,000 died from typhus or malnutrition over the following weeks.[47] The British forced the remaining SS guards to gather up the corpses and place them in mass graves.[48]
