The history of Auschwitz-Birkenau as an extermination center is complex. From late 1941 to October 1942, the mortuary at Auschwitz main camp, which was already equipped with a crematorium, was adapted as a gas chamber. It measured approximately 835 square feet. In the spring of 1942, two provisional gas chambers at Birkenau were constructed out of peasant huts, known as the 'bunkers'.
Otto had prepared a secret hideout next to his place of work. The door was hidden behind some bookshelves. The hideout was small. The first floor had a bathroom and a small kitchen. The second floor had two rooms, one for Anne and Margot and one for her parents. There was also an attic where they stored food and where Anne would sometimes go to be alone. 

Under Nazism, with its emphasis on the nation, individualism was denounced and instead importance was placed upon Germans belonging to the German Volk and "people's community" (Volksgemeinschaft).[272] Hitler declared that "every activity and every need of every individual will be regulated by the collectivity represented by the party" and that "there are no longer any free realms in which the individual belongs to himself".[273] Himmler justified the establishment of a repressive police state, in which the security forces could exercise power arbitrarily, by claiming that national security and order should take precedence over the needs of the individual.[274]
After this we were taken to another room in which we were forced to strip. Then our heads were clipped short and all signs of beard were removed. According to an old tradition in Germany, the cropped hair is a distinguishing mark of the serf in contrast to the free man. After this procedure and a sort of 'medical examination' by another inmate employed as attendant, we received the benefit of a hot shower, which somewhat refreshed us and loosened up our limbs, stiff from the long stand in the cold.

Persecution of the Catholic Church in Germany followed the Nazi takeover.[417] Hitler moved quickly to eliminate political Catholicism, rounding up functionaries of the Catholic-aligned Bavarian People's Party and Catholic Centre Party, which along with all other non-Nazi political parties ceased to exist by July.[418] The Reichskonkordat (Reich Concordat) treaty with the Vatican was signed in 1933, amid continuing harassment of the church in Germany.[314] The treaty required the regime to honour the independence of Catholic institutions and prohibited clergy from involvement in politics.[419] Hitler routinely disregarded the Concordat, closing all Catholic institutions whose functions were not strictly religious.[420] Clergy, nuns and lay leaders were targeted, with thousands of arrests over the ensuing years, often on trumped-up charges of currency smuggling or immorality.[421] Several Catholic leaders were targeted in the 1934 Night of the Long Knives assassinations.[422][423][424] Most Catholic youth groups refused to dissolve themselves and Hitler Youth leader Baldur von Schirach encouraged members to attack Catholic boys in the streets.[425] Propaganda campaigns claimed the church was corrupt, restrictions were placed on public meetings and Catholic publications faced censorship. Catholic schools were required to reduce religious instruction and crucifixes were removed from state buildings.[426]

The Nazi rise to power brought an end to the Weimar Republic, a parliamentary democracy established in Germany after World War I. Following the appointment of Adolf Hitler as chancellor on January 30, 1933, the Nazi state (also referred to as the Third Reich) quickly became a regime in which Germans enjoyed no guaranteed basic rights. After a suspicious fire in the Reichstag (the German Parliament), on February 28, 1933, the government issued a decree which suspended constitutional civil rights and created a state of emergency in which official decrees could be enacted without parliamentary confirmation.
Political concentration camps instituted primarily to reinforce the state’s control have been established in various forms under many totalitarian regimes—most extensively in Nazi Germany and the Soviet Union. To a considerable extent, the camps served as the special prisons of the secret police. Nazi concentration camps were under the administration of the SS; forced-labour camps of the Soviet Union were operated by a succession of organizations beginning in 1917 with the Cheka and ending in the early 1990s with the KGB.
Auschwitz-Birkenau was the largest Nazi extermination and concentration camp, located in the Polish town of Oswiecim, 37 miles west of Cracow. One sixth of all Jews murdered by the Nazis were gassed at Auschwitz. In April 1940 SS chief Heinrich Himmler ordered the establishment of a new concentration camp in Oswiecim, a town located within the portion of Poland that was annexed to Germany at the beginning of World War II. The first Polish political prisoners arrived in Auschwitz in June 1940, and by March 1941 there were 10,900 prisoners, the majority of whom were Polish. Auschwitz soon became known as the most brutal of the Nazi concentration camps.
Until the German invasion, Anne’s childhood in Amsterdam was filled with school and friends—she had attended the Sixth Montessori school in Amsterdam until September 1941, when Jewish children are no longer allowed to go to school with non-Jews. The following spring, in May 1942, all Dutch Jews were required to wear a yellow star of David on their clothing with the word Jood (Jew) written on it. They also had to observe curfews and were barred from public transportation and from using the telephone. In June, Anne turned 13 and received a diary for her birthday—the first volume of three she would keep during the war.

Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.
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]
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.

Most of the judicial system and legal codes of the Weimar Republic remained in place to deal with non-political crimes.[206] The courts issued and carried out far more death sentences than before the Nazis took power.[206] People who were convicted of three or more offences—even petty ones—could be deemed habitual offenders and jailed indefinitely.[207] People such as prostitutes and pickpockets were judged to be inherently criminal and a threat to the community. Thousands were arrested and confined indefinitely without trial.[208]
Racism, especially antisemitism, was a central feature of the regime. The Germanic peoples were considered by the Nazis to be the master race, the purest branch of the Aryan race. Discrimination and persecution against Jews and Romani people began in earnest after the seizure of power. The first concentration camps were established in March 1933. Jews and others deemed undesirable were imprisoned, and liberals, socialists, and communists were killed, imprisoned, or exiled. Christian churches and citizens that opposed Hitler's rule were oppressed, and many leaders imprisoned. Education focused on racial biology, population policy, and fitness for military service. Career and educational opportunities for women were curtailed. Recreation and tourism were organised via the Strength Through Joy program, and the 1936 Summer Olympics showcased Germany on the international stage. Propaganda Minister Joseph Goebbels made effective use of film, mass rallies, and Hitler's hypnotic oratory to influence public opinion. The government controlled artistic expression, promoting specific art forms and banning or discouraging others.
The NSDAP briefly adopted the designation "Nazi"[when?] in an attempt to reappropriate the term, but it soon gave up this effort and generally avoided using the term while it was in power.[10][11] For example, in Hitler's book Mein Kampf, originally published in 1925, he never refers to himself as a "Nazi."[15] A compendium of conversations of Hitler from 1941 through 1944 entitled Hitler's Table Talk does not contain the word "Nazi" either.[16] In speeches by Hermann Göring, he never uses the term "Nazi."[17] Hitler Youth leader Melita Maschmann wrote a book about her experience entitled Account Rendered[18]. She did not refer to herself as a "Nazi," even though she was writing well after World War II. In 1933 581 members of the National Socialist Party answered interview questions put to them by Professor Theodore Abel from Columbia University. They similarly did not refer to themselves as "Nazis."[19] In each case, the authors refer to themselves as "National Socialists" and their movement as "National Socialism," but never as "Nazis."
Beyond that they tried personal defamation. One of our companions was asked by an S. S. man whether he had been a soldier and what rank he had held in the war. He answered, 'Lieutenant.' The S. S. man said, 'But you were only behind the lines.' 'No,' replied our companion, 'I was at the front.' 'I command you to answer this question with "behind the lines,"' the S. S. man corrected him; 'German history would lie if Jews had actually been at the front, so where were you?' And the old soldier, who had come back decorated with high medals from the war in which he had fought and bled for his German fatherland, was forced to answer, 'Behind the lines.'

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]
Although the Nazis won the greatest share of the popular vote in the two Reichstag general elections of 1932, they did not have a majority. Hitler therefore led a short-lived coalition government formed with the German National People's Party.[14] Under pressure from politicians, industrialists, and the business community, President Paul von Hindenburg appointed Hitler as Chancellor of Germany on 30 January 1933. This event is known as the Machtergreifung ("seizure of power").[15]
When asked[when?] whether he supported the "bourgeois right-wing", Hitler claimed that Nazism was not exclusively for any class and he indicated that it favoured neither the left nor the right, but preserved "pure" elements from both "camps" by stating: "From the camp of bourgeois tradition, it takes national resolve, and from the materialism of the Marxist dogma, living, creative Socialism".[26]
The Soviet troops found grisly evidence of the horror. About 7,000 starving prisoners were found alive in the camp. Millions of items of clothing that once belonged to men, women and children were discovered along with 6,350kg of human hair. The Auschwitz museum holds more than 100,000 pairs of shoes, 12,000 kitchen utensils, 3,800 suitcases and 350 striped camp garments.

In 1933, when Adolf Hitler assumed power in the German government, the usage of "Nazi" diminished in Germany, although Austrian anti-Nazis continued to use the term,[18] and the use of "Nazi Germany" and "Nazi regime" was popularised by anti-Nazis and German exiles abroad. Thereafter, the term spread into other languages and eventually was brought back to Germany after World War II.[22] In English, the term is not considered slang, and has such derivatives as Nazism and denazification.

Since the prisoners were now needed for their labour, living conditions improved for a short time. From the end of 1943 onwards, inmates were also deployed in the construction of underground factories, for example those in Melk, Ebensee and St. Georgen an der Gusen. The murderous working conditions that prevailed at these sites soon led to a dramatic rise in the number of victims.
The preservation lab, with high-end technology, opened in 2003. One afternoon last week, Nel Jastrzebiowska, 37, a paper conservator, was using a rubber eraser to clean a row of papers in files. They were letters on Auschwitz stationery, written in German in rosy prose intended to slip past the censors. “I’m in good health,” one read, adding, “Send me money.”
The chief of construction of Auschwitz II-Birkenau was Karl Bischoff, a competent and dynamic bureaucrat who, in spite of the ongoing war, carried out the construction deemed necessary. The Birkenau camp, the four crematoria, a new reception building, and hundreds of other buildings were planned and constructed.[42] Bischoff's plans, based on an initial budget of RM 8.9 million, called for each barracks to hold 550 prisoners. He later changed this to 744 per barracks, which meant the camp could hold 125,000, rather than 97,000.[43] The SS designed the barracks not so much to house people as to destroy them.[42] There were 174 barracks, each measuring 116 by 36 ft, divided into 62 bays of 43 sq. ft. The bays were divided into "roosts", initially for three inmates and later for four. With personal space of 11 sq. ft to sleep and place whatever belongings they had, inmates were deprived, Robert-Jan van Pelt wrote, "of the minimum space needed to exist".[44]
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.

Against the advice of many of his senior military officers, Hitler ordered an attack on France and the Low Countries, which began in May 1940.[97][98] They quickly conquered Luxembourg and the Netherlands. After outmanoeuvring the Allies in Belgium and forcing the evacuation of many British and French troops at Dunkirk,[99] France fell as well, surrendering to Germany on 22 June.[100] The victory in France resulted in an upswing in Hitler's popularity and an upsurge in war fever in Germany.[101]

The first experimental gassing took place in September 1941, when Lagerführer Karl Fritzsch, at the instruction of Rudolf Höss, killed a group of Soviet prisoners of war by throwing Zyklon B crystals into their basement cell in block 11 of Auschwitz I. A second group of 600 Soviet prisoners of war and around 250 sick Polish prisoners was gassed on 3–5 September.[29] The morgue was later converted to a gas chamber able to hold at least 700–800 people.[30] Zyklon B was dropped into the room through slits in the ceiling.[28] In the view of Filip Müller, one of the Sonderkommando who worked in crematorium I, tens of thousands of Jews were killed there from France, Holland, Slovakia, Upper Silesia, Yugoslavia, and from the Theresienstadt, Ciechanow, and Grodno ghettos.[31] The last inmates to be gassed in Auschwitz I, in December 1942, were 300–400 members of the Auschwitz II Sonderkommando, who had been forced to dig up that camp's mass graves, thought to hold 100,000 corpses, and burn the remains.[32]
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.

Oswald Spengler, a German cultural philosopher, was a major influence on Nazism, although after 1933 he became alienated from Nazism and was later condemned by the Nazis for criticising Adolf Hitler.[109] Spengler's conception of national socialism and a number of his political views were shared by the Nazis and the Conservative Revolutionary movement.[110] Spengler's views were also popular amongst Italian Fascists, including Benito Mussolini.[111]
The enormous expansion of the camps resulted in an exponential increase in the misery of the prisoners. Food rations, always meagre, were cut to less than minimal: a bowl of rutabaga soup and some ersatz bread would have to sustain a prisoner doing heavy labor. The result was desperate black marketing and theft. Wachsmann writes, “In Sachsenhausen, a young French prisoner was battered to death in 1941 by an SS block leader for taking two carrots from a sheep pen.” Starvation was endemic and rendered prisoners easy prey for typhus and dysentery. At the same time, the need to keep control of so many prisoners made the S.S. even more brutal, and sadistic new punishments were invented. The “standing commando” forced prisoners to stand absolutely still for eight hours at a time; any movement or noise was punished by beatings. The murder of prisoners by guards, formerly an exceptional event in the camps, now became unremarkable.

Despite the horrible conditions, prisoners in Auschwitz managed to resist the Nazis, including some instances of escape and armed resistance. In October 1944, members of the Sonderkommando, who worked in the crematoria, succeeded in killing several SS men and destroying one gas chamber. All of the rebels died, leaving behind diaries that provided authentic documentation of the atrocities committed at Auschwitz.
Those unable to work – the old, women and children – were immediately sent to the gas chambers or shot in the "camp hospital". Even those able to work ended up in the gas chamber sooner or later, or they fell victim to random shooting actions within a few months, when they had been worn out by the tough work. That is, if they had not died already. Those able to work for instance helped carry the bodies to the crematoria or search the bodies for valuables.
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.
In January 1934, Germany signed a non-aggression pact with Poland.[73] In March 1939, Hitler demanded the return of the Free City of Danzig and the Polish Corridor, a strip of land that separated East Prussia from the rest of Germany. The British announced they would come to the aid of Poland if it was attacked. Hitler, believing the British would not actually take action, ordered an invasion plan should be readied for September 1939.[74] On 23 May, Hitler described to his generals his overall plan of not only seizing the Polish Corridor but greatly expanding German territory eastward at the expense of Poland. He expected this time they would be met by force.[75]
Germany was known as the Weimar Republic during the years 1919 to 1933. It was a republic with a semi-presidential system. The Weimar Republic faced numerous problems, including hyperinflation, political extremism (including violence from left- and right-wing paramilitaries), contentious relationships with the Allied victors of World War I, and a series of failed attempts at coalition government by divided political parties.[2] Severe setbacks to the German economy began after World War I ended, partly because of reparations payments required under the 1919 Treaty of Versailles. The government printed money to make the payments and to repay the country's war debt, but the resulting hyperinflation led to inflated prices for consumer goods, economic chaos, and food riots.[3] When the government defaulted on their reparations payments in January 1923, French troops occupied German industrial areas along the Ruhr and widespread civil unrest followed.[4]
In the Soviet Union by 1922 there were 23 concentration camps for the incarceration of persons accused of political offenses as well as criminal offenses. Many corrective labour camps were established in northern Russia and Siberia, especially during the First Five-Year Plan, 1928–32, when millions of rich peasants were driven from their farms under the collectivization program. The Stalinist purges of 1936–38 brought additional millions into the camps—said to be essentially institutions of slavery.
