For the purpose of centralisation in the Gleichschaltung process a rigidly hierarchal structure was established in the Nazi Party, which it later carried through in the whole of Germany in order to consolidate total power under the person of Hitler (Führerstaat). It was regionally sub-divided into a number of Gaue (singular: Gau) headed by a Gauleiter, who received their orders directly from Hitler. The name (originally a term for sub-regions of the Holy Roman Empire headed by a Gaugraf) for these new provincial structures was deliberately chosen because of its mediaeval connotations. The term is approximately equivalent to the English shire.
Many of the forced labour camps were satellite camps or sections of concentration camps. Auschwitz, in Poland, had over 40 such satellite camps. Inmates of the labour camps were kept in terrible conditions, with the intention by the Nazis that death would be the result. ‘Extermination by labour’ was a policy under which the Nazis could supply the German war effort, while also continuing to carry out ‘the final solution’.
By 1942, Auschwitz had mushroomed into a massive money-making complex that included the original camp, Birkenau (officially labeled Auschwitz II) and 40 sub-camps (mostly located in and around the nearby town of Oswiecim but some as far away as Czechoslovakia) set up to provide slave labor for chemical plants, coal mines, shoe factories and other ventures. In their eagerness to carry out orders, advance their careers and line their own pockets, mid-level bureaucrats like Höss implemented what came to be known as the Holocaust.
On the night of 27 February 1933, the Reichstag building was set afire. Marinus van der Lubbe, a Dutch communist, was found guilty of starting the blaze. Hitler proclaimed that the arson marked the start of a communist uprising. The Reichstag Fire Decree, imposed on 28 February 1933, rescinded most civil liberties, including rights of assembly and freedom of the press. The decree also allowed the police to detain people indefinitely without charges. The legislation was accompanied by a propaganda campaign that led to public support for the measure. Violent suppression of communists by the SA was undertaken nationwide and 4,000 members of the Communist Party of Germany were arrested.[16]
Nazism's racial policy positions may have developed from the views of important biologists of the 19th century, including French biologist Jean-Baptiste Lamarck, through Ernst Haeckel's idealist version of Lamarckism and the father of genetics, German botanist Gregor Mendel.[101] However, Haeckel's works were later condemned and banned from bookshops and libraries by the Nazis as inappropriate for "National-Socialist formation and education in the Third Reich". This may have been because of his "monist" atheistic, materialist philosophy, which the Nazis disliked.[102] Unlike Darwinian theory, Lamarckian theory officially ranked races in a hierarchy of evolution from apes while Darwinian theory did not grade races in a hierarchy of higher or lower evolution from apes, but simply stated that all humans as a whole had progressed in their evolution from apes.[101] Many Lamarckians viewed "lower" races as having been exposed to debilitating conditions for too long for any significant "improvement" of their condition to take place in the near future.[103] Haeckel utilised Lamarckian theory to describe the existence of interracial struggle and put races on a hierarchy of evolution, ranging from wholly human to subhuman.[101]

With Hitler's approval, Himmler intended that the new society of the Nazi regime should destigmatise illegitimate births, particularly of children fathered by members of the SS, who were vetted for racial purity.[385] His hope was that each SS family would have between four and six children.[385] The Lebensborn (Fountain of Life) association, founded by Himmler in 1935, created a series of maternity homes to accommodate single mothers during their pregnancies.[386] Both parents were examined for racial suitability before acceptance.[386] The resulting children were often adopted into SS families.[386] The homes were also made available to the wives of SS and NSDAP members, who quickly filled over half the available spots.[387]
But, in May 1944, a railroad spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944. From then to November 1944, when all the other death camps had been abandoned, Birkenau surpassed all previous records for mass killing. The Hungarian deportations and the liquidation of the remaining Polish ghettos, such as Lodz, resulted in the gassing of 585,000 Jews. This period made Auschwitz-Birkenau into the most notorious killing site of all time.
Fascism was a major influence on Nazism. The seizure of power by Italian Fascist leader Benito Mussolini in the March on Rome in 1922 drew admiration by Hitler, who less than a month later had begun to model himself and the Nazi Party upon Mussolini and the Fascists.[121] Hitler presented the Nazis as a form of German fascism.[122][123] In November 1923, the Nazis attempted a "March on Berlin" modelled after the March on Rome, which resulted in the failed Beer Hall Putsch in Munich.[124]
In its racial categorization, Nazism viewed what it called the Aryan race as the master race of the world—a race that was superior to all other races.[136] It viewed Aryans as being in racial conflict with a mixed race people, the Jews, whom the Nazis identified as a dangerous enemy of the Aryans. It also viewed a number of other peoples as dangerous to the well-being of the Aryan race. In order to preserve the perceived racial purity of the Aryan race, a set of race laws was introduced in 1935 which came to be known as the Nuremberg Laws. At first these laws only prevented sexual relations and marriages between Germans and Jews, but they were later extended to the "Gypsies, Negroes, and their bastard offspring", who were described by the Nazis as people of "alien blood".[137][138] Such relations between Aryans (cf. Aryan certificate) and non-Aryans were now punishable under the race laws as Rassenschande or "race defilement".[137] After the war began, the race defilement law was extended to include all foreigners (non-Germans).[139] At the bottom of the racial scale of non-Aryans were Jews, Romanis, Slavs[140] and blacks.[141] To maintain the "purity and strength" of the Aryan race, the Nazis eventually sought to exterminate Jews, Romani, Slavs and the physically and mentally disabled.[140][142] Other groups deemed "degenerate" and "asocial" who were not targeted for extermination, but were subjected to exclusionary treatment by the Nazi state, included homosexuals, blacks, Jehovah's Witnesses and political opponents.[142] One of Hitler's ambitions at the start of the war was to exterminate, expel or enslave most or all Slavs from Central and Eastern Europe in order to acquire living space for German settlers.[143]
The Nazi Party Programme of 1920 guaranteed freedom for all religious denominations which were not hostile to the State and it also endorsed Positive Christianity in order to combat "the Jewish-materialist spirit".[207] Positive Christianity was a modified version of Christianity which emphasized racial purity and nationalism.[208] The Nazis were aided by theologians such as Ernst Bergmann. In his work Die 25 Thesen der Deutschreligion (Twenty-five Points of the German Religion), Bergmann held the view that the Old Testament of the Bible was inaccurate along with portions of the New Testament, claimed that Jesus was not a Jew but was instead of Aryan origin and he also claimed that Adolf Hitler was the new messiah.[208]
On 2 August 1934, Hindenburg died. The previous day, the cabinet had enacted the "Law Concerning the Highest State Office of the Reich", which stated that upon Hindenburg's death the office of president would be abolished and its powers merged with those of the chancellor.[39] Hitler thus became head of state as well as head of government and was formally named as Führer und Reichskanzler ("Leader and Chancellor") – although eventually Reichskanzler was dropped.[40] Germany was now a totalitarian state with Hitler at its head.[41] As head of state, Hitler became Supreme Commander of the armed forces. The new law provided an altered loyalty oath for servicemen so that they affirmed loyalty to Hitler personally rather than the office of supreme commander or the state.[42] On 19 August, the merger of the presidency with the chancellorship was approved by 90 percent of the electorate in a plebiscite.[43]

Auschwitz-Birkenau became the killing centre where the largest numbers of European Jews were killed during the Holocaust. After an experimental gassing there in September 1941 of 850 malnourished and ill prisoners, mass murder became a daily routine. By mid 1942, mass gassing of Jews using Zyklon-B began at Auschwitz, where extermination was conducted on an industrial scale with some estimates running as high as three million persons eventually killed through gassing, starvation, disease, shooting, and burning ...
Gradowski was one of the Jewish prisoners in Auschwitz’s Sonderkommando: those forced to escort new arrivals into the gas chambers, haul the newly dead bodies to the crematoriums, extract any gold teeth and then burn the corpses. Gradowski, a young married man whose entire family was murdered, reportedly maintained his religious faith, reciting the kaddish (mourner’s prayer) each evening for the victims of each transport—including Peter van Pels’ father, who was gassed a few weeks after his arrival in Auschwitz on September 6, 1944. Gradowski recorded his experiences in Yiddish in documents he buried, which were discovered after the war; he himself was killed on October 7, 1944, in a Sonderkommando revolt that lasted only one day. (The documents written by Gradowski and several other prisoners inspired the 2015 Hungarian film Son of Saul, which, unsurprisingly, was no blockbuster, despite an Academy Award and critical acclaim.)

Hitler added to Pan-Germanic aspirations the almost mystical fanaticism of a faith in the mission of the German race and the fervour of a social revolutionary gospel. This gospel was most fully expressed in Hitler’s personal testament Mein Kampf (1925–27; “My Struggle”), in which he outlined both his practical aims and his theories of race and propaganda.

As the Russians closed in on Auschwitz, the Germans became desperate, destroying as much evidence of war crimes as they could, including records and property seized from prisoners, and forcing as many prisoners as they could on what became death marches. The day before the Russian Army liberated Auschwitz, Edith died there. On January 27 Otto was liberated and taken to Odessa and then France before being allowed to return to Amsterdam in June 1945.

Hitler’s most important individual contribution to the theory and practice of Nazism was his deep understanding of mass psychology and mass propaganda. He stressed the fact that all propaganda must hold its intellectual level at the capacity of the least intelligent of those at whom it is directed and that its truthfulness is much less important than its success. According to Hitler:
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.
Born in Baden-Baden in 1900,[78] SS Obersturmbannführer Rudolf Höss became the first commandant of Auschwitz when the camp was founded in April 1940,[79] living with his wife and children in a villa just outside the camp grounds.[80] Appointed by Heinrich Himmler, he served until 11 November 1943, when he became director of Office DI of the SS-Wirtschafts-und Verwaltungshauptamt (SS Business and Administration Head Office or WVHA) in Oranienburg.[79] This post made Höss deputy of the Concentration Camps Inspectorate, under SS-Gruppenführer Richard Glücks.[81] He returned to Auschwitz between 8 May and 29 July 1944 as commander of the SS garrison (Standortältester) to oversee the arrival of Hungary's Jews, a post that made him the superior officer of all the commandants of the Auschwitz camps.[82]
In every camp, Allied soldiers encountered appalling scenes. Bergen-Belsen was liberated by British forces on 15 April 1945. It had become exceptionally overcrowded after the arrival of survivors of the death marches. Thousands of unburied bodies lay strewn around the camp, while in the barracks some 60,000 starving and mortally ill people were packed together without food or water. The mortality rate amongst those suffering from typhus was over 60 per cent.
Following the June 1941 German invasion of the Soviet Union, the Nazis increased the number of prisoner-of-war (POW) camps. Some new camps were built at existing concentration camp complexes (such as Auschwitz) in occupied Poland. The camp at Lublin, later known as Majdanek, was established in the autumn of 1941 as a POW camp and became a concentration camp in 1943. Thousands of Soviet POWs were shot or gassed there.
On 31 July 1941 Hermann Göring gave written authorization to SS-Obergruppenführer Reinhard Heydrich, Chief of the Reich Main Security Office (RSHA), to prepare and submit a plan for a "total solution of the Jewish question" in territories under German control and to coordinate the participation of all involved government organisations.[33] The resulting Generalplan Ost (General Plan for the East) called for deporting the population of occupied Eastern Europe and the Soviet Union to Siberia, for use as slave labour or to be murdered.[34]
