In the spring of 1941, German conglomerate I.G. Farben established a factory in which its executives intended to exploit concentration camp labor to manufacture synthetic rubber and fuels. I.G. Farben invested more than 700 million Reichsmarks (about 2.8 million US dollars in 1941 terms) in Auschwitz III. From May 1941 until July 1942, the SS had transported prisoners from Auschwitz I to the “Buna Detachment,” at first on foot and later by rail. (Between July and October 1942 there was a pause in transports, due to a typhus epidemic and quarantine.) With the construction of Auschwitz III in the autumn of 1942, prisoners deployed at Buna lived in Auschwitz III.
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.
Frank frequently wrote of her difficult relationship with her mother, and of her ambivalence towards her. On 7 November 1942 she described her "contempt" for her mother and her inability to "confront her with her carelessness, her sarcasm and her hard-heartedness," before concluding, "She's not a mother to me."[32] Later, as she revised her diary, Frank felt ashamed of her harsh attitude, writing: "Anne, is it really you who mentioned hate, oh Anne, how could you?"[33] She came to understand that their differences resulted from misunderstandings that were as much her fault as her mother's, and saw that she had added unnecessarily to her mother's suffering. With this realization, Frank began to treat her mother with a degree of tolerance and respect.[34]
Sunday was not a work day, but prisoners were required to clean the barracks and take their weekly shower,[115] and were allowed to write (in German) to their families, although the SS censored the outgoing mail. Inmates who did not speak German would trade some of their bread for help composing their letters.[116] Observant Jews tried to keep track of the Hebrew calendar and Jewish holidays, including Shabbat, and the weekly Torah portion. No watches, calendars, or clocks were permitted in the camp. Jewish calendars were rare among prisoners; being in possession of one was dangerous. Only two Jewish calendars made in Auschwitz survived to the end of the war. Prisoners kept track of the days in other ways, such as obtaining information from newcomers.[117]
…party, Hitler joined a German nationalist group that took the name of National Socialist German Workers’ Party (Nationalsozialistische Deutsche Arbeiterpartei), nicknamed “Nazi,” a truncation of Nationalsozialistische. Its policies included anti-Semitism and fierce opposition to the Treaty of Versailles. After his abortive Munich coup in 1923, Hitler was sentenced to five…

Up to this point, though, Auschwitz-Birkenau accounted for “only” 11 percent of the victims of the “Final Solution.” In August 1942, however, construction began on four large-scale gassing facilities. It appears from the plans that the first two gas chambers were adapted from mortuaries which, with the huge crematoria attached to them, were initially intended to cope with mortalities amongst the slave labor force in the camp, now approaching 100,000 and subject to a horrifying death rate. But from the autumn of 1942, it seems clear that the SS planners and civilian contractors were intending to build a mass-murder plant.
Historians regard the equation of National Socialism as 'Hitlerism' as too simplistic since the term was used prior to the rise of Hitler and the Nazis and the different ideologies incorporated into Nazism were already well established in certain parts of German society before World War I.[27] The Nazis were strongly influenced by the post–World War I far-right in Germany, which held common beliefs such as anti-Marxism, anti-liberalism and antisemitism, along with nationalism, contempt for the Treaty of Versailles and condemnation of the Weimar Republic for signing the armistice in November 1918 which later led it to sign the Treaty of Versailles.[28] A major inspiration for the Nazis were the far-right nationalist Freikorps, paramilitary organizations that engaged in political violence after World War I.[28] Initially, the post–World War I German far-right was dominated by monarchists, but the younger generation, which was associated with Völkisch nationalism, was more radical and it did not express any emphasis on the restoration of the German monarchy.[29] This younger generation desired to dismantle the Weimar Republic and create a new radical and strong state based upon a martial ruling ethic that could revive the "Spirit of 1914" which was associated with German national unity (Volksgemeinschaft).[29]
The Theresienstadt family camp, which existed between September 1943 and July 1944, served a different purpose. A group of around 5,000 Jews had arrived in Auschwitz in September 1943 from the Theresienstadt ghetto in Czechoslovakia. The families were allowed to stay together, their heads were not shaved, and they could wear their own clothes. Correspondence between Adolf Eichmann's office and the International Red Cross suggests that the Germans set up the camp to cast doubt on reports, in time for a planned Red Cross visit to Auschwitz, that mass murder was taking place in Auschwitz. A second group of 5,000 arrived from Theresienstadt in December 1943. On 7 March 1944, the first group was sent to the gas chamber at crematorium III; before they died, they were asked to send postcards to relatives, postdated to 25 March.[149] This was the largest massacre of Czechoslovak citizens in history. News of the liquidation reached the Czechoslovak government-in-exile, which initiated diplomatic manoeuvers to save the remaining Jews. After the Red Cross visited Theresienstadt in June 1944 and were persuaded by the SS that no deportations were taking place from there, about 3,500 Jews were removed from the family camp to other sections of Auschwitz. The remaining 6,500 were murdered in the gas chambers between 10 and 12 July 1944.[150][151]
I recall the time in Auschwitz as single moments, short encounters, smells. We tried to distract ourselves from the reality of it by trying to recall our home lives in what turned into a game of momentary escapism. Quietly, the children would huddle together and ask each other: “What will you have for breakfast?” And I remember saying: “Maybe an egg or a piece of bread and butter,” and tried to conjure up memories of home.
The employees of large businesses with international operations such as Deutsche Bank, Dresdner Bank, and Commerzbank were mostly party members.[105] All German businesses abroad were also required to have their own Nazi Party Ausland-Organization liaison men, which enabled the party leadership updated and excellent intelligence on the actions of the global corporate elites.[106]
Witnesses later testified Margot fell from her bunk in her weakened state and was killed by the shock. Anne died a few days after Margot. The exact dates of Margot's and Anne's deaths were not recorded. It was long thought that their deaths occurred only a few weeks before British soldiers liberated the camp on 15 April 1945,[59] but research in 2015 indicated that they may have died as early as February.[60] Among other evidence, witnesses recalled that the Franks displayed typhus symptoms by 7 February,[3][61] and Dutch health authorities reported that most untreated typhus victims died within 12 days of their first symptoms.[60] After liberation, the camp was burned in an effort to prevent further spread of disease; the sisters were buried in a mass grave at an unknown location.
The unified armed forces of Germany from 1935 to 1945 were called the Wehrmacht (defence force). This included the Heer (army), Kriegsmarine (navy), and the Luftwaffe (air force). From 2 August 1934, members of the armed forces were required to pledge an oath of unconditional obedience to Hitler personally. In contrast to the previous oath, which required allegiance to the constitution of the country and its lawful establishments, this new oath required members of the military to obey Hitler even if they were being ordered to do something illegal.[219] Hitler decreed that the army would have to tolerate and even offer logistical support to the Einsatzgruppen—the mobile death squads responsible for millions of deaths in Eastern Europe—when it was tactically possible to do so.[220] Wehrmacht troops also participated directly in the Holocaust by shooting civilians or committing genocide under the guise of anti-partisan operations.[221] The party line was that the Jews were the instigators of the partisan struggle and therefore needed to be eliminated.[222] On 8 July 1941, Heydrich announced that all Jews in the eastern conquered territories were to be regarded as partisans and gave the order for all male Jews between the ages of 15 and 45 to be shot.[223] By August this was extended to include the entire Jewish population.[224]

In Autumn 1943, the camp administration was reorganized following a corruption scandal. By the end of 1943, the prisoner population of Auschwitz main camp, Birkenau, Monowitz and other subcamps was over 80,000: 18,437 in the main camp, 49,114 in Birkenau, and 13,288 at Monowitz where I G Farben had its synthetic rubber plant. Up to 50,000 prisoners were scattered around 51 subcamps such as Rajsko, an experimental agricultural station, and Gleiwitz, a coal mine (see The List of the Camps for a complete list of those subcamps).
The SS gained its independence from the SA in July 1934, in the wake of the Röhm purge. Hitler then authorized SS leader Heinrich Himmler to centralize the administration of the concentration camps and formalize them into a system. Himmler chose SS Lieutenant General Theodor Eicke for this task. Eicke had been the commandant of the SS concentration camp at Dachau since June 1933. Himmler appointed him Inspector of Concentration Camps, a new section of the SS subordinate to the SS Main Office.
It is surprising to me that inmates make any attempt to escape. Already in the first hours of our stay we could convince ourselves of the hopelessness of such an undertaking, being lined up as we were along the inner wall. The watchtowers were occupied by S.S. men with machine guns, and during the darkness rays of searchlights played from them. The guards in the watchtowers, provided with field glasses, were able to see each inmate who might move outside the barracks during the night hours, and they had strict orders to fire at an offender at once. Aside from these guards, mechanical contraptions made escape almost impossible. On the inner sides of the two encircling walls there were tall wire fences charged with a high-voltage current. Inside the wire fence there was a small strip of gravel, in front of which were signs bearing skull and crossbones and this inscription: 'Caution neutral zone.' The guards were instructed to shoot without warning at anybody entering this zone.
All of their clothes and any remaining personal belongings were taken from them and their hair was shorn completely off. They were given striped prison outfits and a pair of shoes, all of which were usually the wrong size. They were then registered, had their arms tattooed with a number, and transferred to one of Auschwitz's camps for forced labor.
The K.L. was defined from the beginning by its legal ambiguity. The camps were outside ordinary law, answerable not to judges and courts but to the S.S. and Himmler. At the same time, they were governed by an extensive set of regulations, which covered everything from their layout (including decorative flower beds) to the whipping of prisoners, which in theory had to be approved on a case-by-case basis by Himmler personally. Yet these regulations were often ignored by the camp S.S.—physical violence, for instance, was endemic, and the idea that a guard would have to ask permission before beating or even killing a prisoner was laughable. Strangely, however, it was possible, in the prewar years, at least, for a guard to be prosecuted for such a killing. In 1937, Paul Zeidler was among a group of guards who strangled a prisoner who had been a prominent churchman and judge; when the case attracted publicity, the S.S. allowed Zeidler to be charged and convicted. (He was sentenced to a year in jail.)
A play by Frances Goodrich and Albert Hackett based upon the diary premiered in New York City on 5 October 1955, and later won a Pulitzer Prize for Drama. It was followed by the film The Diary of Anne Frank (1959), which was a critical and commercial success. Biographer Melissa Müller later wrote that the dramatization had "contributed greatly to the romanticizing, sentimentalizing and universalizing of Anne's story."[73] Over the years the popularity of the diary grew, and in many schools, particularly in the United States, it was included as part of the curriculum, introducing Anne Frank to new generations of readers.[74]
The DAP was a comparatively small group with fewer than 60 members.[30] Nevertheless, it attracted the attention of the German authorities, who were suspicious of any organisation that appeared to have subversive tendencies. In July 1919, while stationed in Munich army Gefreiter Adolf Hitler was appointed a Verbindungsmann (intelligence agent) of an Aufklärungskommando (reconnaissance unit) of the Reichswehr (army) by Captain Mayr the head of the Education and Propaganda Department (Dept Ib/P) in Bavaria. Hitler was assigned to influence other soldiers and to infiltrate the DAP.[33] While attending a party meeting on 12 September 1919, Hitler became involved in a heated argument with a visitor, Professor Baumann, who questioned the soundness of Gottfried Feder's arguments against capitalism; Baumann proposed that Bavaria should break away from Prussia and found a new South German nation with Austria. In vehemently attacking the man's arguments, Hitler made an impression on the other party members with his oratorical skills; according to Hitler, the "professor" left the hall acknowledging unequivocal defeat.[34] Drexler encouraged him to join the DAP.[34] On the orders of his army superiors, Hitler applied to join the party[35] and within a week was accepted as party member 555 (the party began counting membership at 500 to give the impression they were a much larger party).[36][37] Among the party's earlier members were Ernst Röhm of the Army's District Command VII; Dietrich Eckart, who has been called the spiritual father of National Socialism;[38] then-University of Munich student Rudolf Hess;[39] Freikorps soldier Hans Frank; and Alfred Rosenberg, often credited as the philosopher of the movement. All were later prominent in the Nazi regime.[40]
The Nazis later issued similar regulations against the Eastern Workers (Ost-Arbeiters), including the imposition of the death penalty if they engaged in sexual relations with German persons.[194] Heydrich issued a decree on 20 February 1942 which declared that sexual intercourse between a German woman and a Russian worker or prisoner of war would result in the Russian man being punished with the death penalty.[195] Another decree issued by Himmler on 7 December 1942 stated that any "unauthorised sexual intercourse" would result in the death penalty.[196] Because the Law for the Protection of German Blood and German Honour did not permit capital punishment for race defilement, special courts were convened in order to allow the death penalty to be imposed in some cases.[197] German women accused of race defilement were marched through the streets with their head shaven and placards detailing their crimes were placed around their necks[198] and those convicted of race defilement were sent to concentration camps.[190] When Himmler reportedly asked Hitler what the punishment should be for German girls and German women who were found guilty of race defilement with prisoners of war (POWs), he ordered that "every POW who has relations with a German girl or a German would be shot" and the German woman should be publicly humiliated by "having her hair shorn and being sent to a concentration camp".[199]

In 2015, Flemish journalist Jeroen de Bruyn and Joop van Wijk, Bep Voskuijl's youngest son, wrote a biography, Bep Voskuijl, het zwijgen voorbij: een biografie van de jongste helper van het Achterhuis (Bep Voskuijl, the Silence is Over: A Biography of the Youngest Helper of the Secret Annex), in which they alleged that Bep's younger sister Nelly (1923–2001) could have betrayed the Frank family. According to the book, Bep's sister Diny and her fiancé Bertus Hulsman recollected Nelly telephoning the Gestapo on the morning of 4 August 1944.[42][43] Nelly had been critical of Bep and their father, Johannes Voskuijl, helping the Jews. (Johannes was the one who constructed the bookcase covering the entrance to the hiding place.)[44] Nelly was a Nazi collaborator between the ages of 19 and 23.[45] Karl Silberbauer, the SS officer who received the phone call and made the arrest, was documented to say that the informer had "the voice of a young woman".[43]

In addition to the Nazi Party proper, several paramilitary groups existed which "supported" Nazi aims. All members of these paramilitary organisations were required to become regular Nazi Party members first and could then enlist in the group of their choice. An exception was the Waffen-SS, considered the military arm of the SS and Nazi Party, which during the Second World War allowed members to enlist without joining the Nazi Party. Foreign volunteers of the Waffen-SS were also not required to be members of the Nazi Party, although many joined local nationalist groups from their own countries with the same aims. Police officers, including members of the Gestapo, frequently held SS rank for administrative reasons (known as "rank parity") and were likewise not required to be members of the Nazi Party.
As Soviet troops approached Auschwitz in January 1945, most of its population was sent west on a death march. The remaining prisoners were liberated on 27 January 1945, a day commemorated as International Holocaust Remembrance Day. In the following decades, survivors such as Primo Levi, Viktor Frankl, and Elie Wiesel wrote memoirs of their experiences in Auschwitz, and the camp became a dominant symbol of the Holocaust. In 1947 Poland founded the Auschwitz-Birkenau Memorial and Museum on the site of Auschwitz I and II, and in 1979 it was named a World Heritage Site by UNESCO.
Germany regained control of the Saarland through a referendum held in 1935 and annexed Austria in the Anschluss of 1938.[164] The Munich Agreement of 1938 gave Germany control of the Sudetenland, and they seized the remainder of Czechoslovakia six months later.[70] Under threat of invasion by sea, Lithuania surrendered the Memel district in March 1939.[165]
Early camps, usually without proper infrastructure, sprang up everywhere in Germany after Hitler became Chancellor in January 1933: rising "like mushrooms after the rain", Himmler recollected.[51] These early camps, also called "Wild camps" because some were set up with little supervision from higher authorities, were overseen by Nazi paramilitaries, by political-police forces, and sometimes by local police authorities. They utilized any lockable larger space, for example: engine rooms, brewery floors, storage facilities, cellars, etc.[52]
