Following Nazi Germany's defeat in World War II and the end of the Holocaust, overt expressions of support for Nazi ideas were prohibited in Germany and other European countries. Nonetheless, movements which self-identify as National Socialist or which are described as adhering to National Socialism continue to exist on the fringes of politics in many western societies. Usually espousing a white supremacist ideology, many deliberately adopt the symbols of Nazi Germany.[288]
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.
At universities, appointments to top posts were the subject of power struggles between the education ministry, the university boards, and the National Socialist German Students' League.[361] In spite of pressure from the League and various government ministries, most university professors did not make changes to their lectures or syllabus during the Nazi period.[362] This was especially true of universities located in predominantly Catholic regions.[363] Enrolment at German universities declined from 104,000 students in 1931 to 41,000 in 1939, but enrolment in medical schools rose sharply as Jewish doctors had been forced to leave the profession, so medical graduates had good job prospects.[364] From 1934, university students were required to attend frequent and time-consuming military training sessions run by the SA.[365] First-year students also had to serve six months in a labour camp for the Reich Labour Service; an additional ten weeks service were required of second-year students.[366]
When a mother did not want to be separated from her thirteen-year-old daughter, and bit and scratched the face of the SS man who tried to force her to her assigned line, Mengele drew his gun and shot both the woman and the child. As a blanket punishment, he sent to the gas chamber all people from that transport who had previously been selected for work, with the comment: Away with this shit! 
Drancy held 5,000 prisoners. Around 70,000 mainly Jewish prisoners passed through the camp between August 1941 and August 1944. On 22 June 1942, the Nazis began systematic deportations of Jews from Drancy to the extermination camps in occupied Poland. In the first transport 1,000 Jews were sent to Auschwitz-Birkenau. By the last transport on 31 July 1944, 64,759 Jews had been deported from Drancy in 64 transports. Approximately 61,000 of these Jews were sent to Auschwitz-Birkenau. A further 3,753 Jews had been transported to Sobibor.
The courtyard between blocks 10 and 11, known as the "death wall" served as an execution area for Poles not in Auschwitz who had been sentenced to death by a criminal court—presided over by German judges—including for petty crimes such as stealing food.[139] Several rooms in block 11 were deemed the Polizei-Ersatz-Gefängnis Myslowitz in Auschwitz ("Alternative jail of the police station at Mysłowice").[140] There were also Sonderbehandlung cases ("special treatment") for Poles and others regarded as dangerous to the Third Reich.[141] Members of the camp resistance were shot there, as were 200 of the Sonderkommandos who took part in the Sonderkommando revolt in October 1944.[142] Thousands of Poles were executed at the death wall; Höss wrote that "execution orders arrived in an unbroken stream".[143]

In September 1933, an important policy document known as the Prussian Memorandum began circulating among lawmakers and jurists of the Third Reich. The Nazi regime was still in its infancy; Hitler had been named chancellor just nine months prior, the result of a power-sharing arrangement with nationalist conservatives who thought they could control the mercurial Austrian. Following the Reichstag Fire in February of that year, Hitler had assumed emergency powers and within weeks usurped the authority of the parliament. By that critical autumn, the Third Reich had begun Nazifying the German legal code. The Prussian Memorandum that passed between Nazi legal hands was an early blueprint for the 1935 Nuremberg Laws, which stripped Jews of their citizenship and criminalized sexual relations between Germans and those thought to have impure blood. It was the foundational text of Nazi legal thinking. Incredibly, the Prussian Memorandum expressly cited the gold standard of racist lawmaking at the time: the United States of America.

After a fortnight we were able to use the money which we had brought in or was sent to us, and it became possible to complete and improve our diet from the canteen at our own expense. We were lined up in rows exactly in the order of our prison numbers, which had been sewed in black on white on our clothes. (This also is penitentiary procedure, for an inmate of the penitentiary is not an individual any more, but only a numbered being without a name.) Then we were led into the barracks where an S.S. man sitting behind a sort of teller's window disbursed the desired sum, up to fifteen marks a week. Somehow I must have transgressed against the military discipline in this procedure. I presume that I had my cap in the wrong hand. Instead of the money I received a violent blow on the back of my hand with a heavy stick which was lying next to the paymaster on his table, obviously for such purposes. Many weeks after this experience the back of my hand was still painful and swollen.
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.

Hitler's talent as an orator and his ability to draw new members, combined with his characteristic ruthlessness, soon made him the dominant figure. However, while Hitler and Eckart were on a fundraising trip to Berlin in June 1921, a mutiny broke out within the party in Munich. Members of its executive committee wanted to merge with the rival German Socialist Party (DSP).[60] Upon returning to Munich on 11 July, Hitler angrily tendered his resignation. The committee members realised that his resignation would mean the end of the party.[61] Hitler announced he would rejoin on condition that he would replace Drexler as party chairman, and that the party headquarters would remain in Munich.[62] The committee agreed, and he rejoined the party on 26 July as member 3,680. Hitler continued to face some opposition within the NSDAP, as his opponents had Hermann Esser expelled from the party and they printed 3,000 copies of a pamphlet attacking Hitler as a traitor to the party.[62] In the following days, Hitler spoke to several packed houses and defended himself and Esser to thunderous applause.[63]
The Germans isolated all the camps and sub-camps from the outside world and surrounded them with barbed wire fencing. All contact with the outside world was forbidden. However, the area administered by the commandant and patrolled by the SS camp garrison went beyond the grounds enclosed by barbed wire. It included an additional area of approximately 40 square kilometers (the so-called “Interessengebiet” - the interest zone), which lay around the Auschwitz I and Auschwitz II-Birkenau camps.
The reality of where we were, struck home fairly quickly. I was stationed near crematorium number four, and we witnessed the columns of unsuspecting women and children entering the gate of the crematorium; they would have been dead within half an hour. When the Hungarian Jews arrived they had the gas chambers going day and night. How can you wrap your imagination round that? I still can’t.
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]
From the start of the war, a British blockade on shipments to Germany affected its economy. Germany was particularly dependent on foreign supplies of oil, coal, and grain.[92] Thanks to trade embargoes and the blockade, imports into Germany declined by 80 per cent.[93] To safeguard Swedish iron ore shipments to Germany, Hitler ordered the invasion of Denmark and Norway, which began on 9 April. Denmark fell after less than a day, while most of Norway followed by the end of the month.[94][95] By early June, Germany occupied all of Norway.[96]
On about 17 January or 18 January 1945, the SS dragged thousands of us out of the camp to walk to Ravensbrück concentration camp deep into central Germany. I don’t really know why. We were in terrible straits with no proper clothes, nothing suitable for marching through the snow. It was as if the cruelty would never end. If anyone sat down out of exhaustion, they were shot. Later we were transported yet again, and my aunt Piri became ill and was killed.
Günther emphasized Jews' Near Eastern racial heritage.[155] Günther identified the mass conversion of the Khazars to Judaism in the 8th century as creating the two major branches of the Jewish people, those of primarily Near Eastern racial heritage became the Ashkenazi Jews (that he called Eastern Jews) while those of primarily Oriental racial heritage became the Sephardi Jews (that he called Southern Jews).[156] Günther claimed that the Near Eastern type was composed of commercially spirited and artful traders, that the type held strong psychological manipulation skills which aided them in trade.[155] He claimed that the Near Eastern race had been "bred not so much for the conquest and exploitation of nature as it had been for the conquest and exploitation of people".[155] Günther believed that European peoples had a racially motivated aversion to peoples of Near Eastern racial origin and their traits, and as evidence of this he showed multiple examples of depictions of satanic figures with Near Eastern physiognomies in European art.[157]

In the spring of 1941, the SS—along with doctors and officials of the T-4 Euthanasia Program—introduced the Action 14f13 programme meant for extermination of selected concentration camp prisoners.[31] The Inspectorate of the Concentration Camps categorized all files dealing with the death of prisoners as 14f, and those of prisoners sent to the T-4 gas chambers as 14f13. Under the language regulations of the SS, selected prisoners were designated for "special treatment (German: Sonderbehandlung) 14f13". Prisoners were officially selected based on their medical condition; namely, those permanently unfit for labor due to illness. Unofficially, racial and eugenic criteria were used: Jews, the handicapped, and those with criminal or antisocial records were selected.[32]:p.144 For Jewish prisoners there was not even the pretense of a medical examination: the arrest record was listed as a physician's "diagnosis".[32]:pp. 147–148 In early 1943, as the need for labor increased and the gas chambers at Auschwitz became operational, Heinrich Himmler ordered the end of Action 14f13.[32]:p.150
