A parallel system operated later at Birkenau in 1942-43, except that for the majority the 'showers' proved to be gas chambers. Only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the 'central sauna' before being assigned barracks. In May 1944, a 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.
The commander of Auschwitz-Birkenau, Rudolf Höss, stated in his autobiography that in 1941 (no exact date is given) he was summoned to Berlin, where Himmler informed him that Hitler had issued an order to solve the “Jewish Question” for good, and that the order was to be implemented by the SS. “The existing extermination places in the east are unsuited to a large scale, long-term action. I have designated Auschwitz for this purpose,” Himmler said.
Estimates of the total German war dead range from 5.5 to 6.9 million persons.[149] A study by German historian Rüdiger Overmans puts the number of German military dead and missing at 5.3 million, including 900,000 men conscripted from outside of Germany's 1937 borders.[150] Richard Overy estimated in 2014 that about 353,000 civilians were killed in Allied air raids.[151] Other civilian deaths include 300,000 Germans (including Jews) who were victims of Nazi political, racial, and religious persecution[152] and 200,000 who were murdered in the Nazi euthanasia program.[153] Political courts called Sondergerichte sentenced some 12,000 members of the German resistance to death, and civil courts sentenced an additional 40,000 Germans.[154] Mass rapes of German women also took place.[155]
In 1919, army veteran Adolf Hitler, frustrated by Germany’s defeat in World War, which had left the nation economically depressed and politically unstable, joined a fledgling political organization called the German Workers’ Party. Founded earlier that same year by a small group of men including locksmith Anton Drexler (1884-1942) and journalist Karl Harrer (1890-1926), the party promoted German nationalism and anti-Semitism, and felt that the Treaty of Versailles, the peace settlement that ended the war, was extremely unjust to Germany by burdening it with reparations it could never pay. Hitler soon emerged as a charismatic public speaker and began attracting new members with speeches blaming Jews and Marxists for Germany’s problems and espousing extreme nationalism and the concept of an Aryan “master race.” In July 1921, he assumed leadership of the organization, which by then had been renamed the Nationalist Socialist German Workers’ (Nazi) Party.
The Allied powers organised war crimes trials, beginning with the Nuremberg trials, held from November 1945 to October 1946, of 23 top Nazi officials. They were charged with four counts—conspiracy to commit crimes, crimes against peace, war crimes and crimes against humanity—in violation of international laws governing warfare.[483] All but three of the defendants were found guilty and twelve were sentenced to death.[484] Twelve Subsequent Nuremberg trials of 184 defendants were held between 1946 and 1949.[483] Between 1946 and 1949, the Allies investigated 3,887 cases, of which 489 were brought to trial. The result was convictions of 1,426 people; 297 of these were sentenced to death and 279 to life in prison, with the remainder receiving lesser sentences. About 65 percent of the death sentences were carried out.[485] Poland was more active than other nations in investigating war crimes, for example prosecuting 673 of the total 789 Auschwitz staff brought to trial.[486]
With Otto Frank's death in 1980, the original diary, including letters and loose sheets, was willed to the Dutch Institute for War Documentation,[97] which commissioned a forensic study of the diary through the Netherlands Ministry of Justice in 1986. They examined the handwriting against known examples and found that they matched. They determined that the paper, glue, and ink were readily available during the time the diary was said to have been written. They concluded that the diary is authentic, and their findings were published in what has become known as the "Critical Edition" of the diary.[98] In 1990, the Hamburg Regional Court confirmed the diary's authenticity.[75]
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]

On 4 September 2003, despite a protest from the museum, three Israeli Air Force F-15 Eagles performed a fly-over of Auschwitz II-Birkenau during a ceremony at the camp below. All three pilots were descendants of Holocaust survivors, including the man who led the flight, Major-General Amir Eshel.[298] On 27 January 2015, some 300 Auschwitz survivors gathered with world leaders under a giant tent at the entrance to Auschwitz II to commemorate the 70th anniversary of the camp's liberation.[299][i]
Spengler's notions of "Prussian socialism" as described in his book Preussentum und Sozialismus ("Prussiandom and Socialism", 1919), influenced Nazism and the Conservative Revolutionary movement.[110] Spengler wrote: "The meaning of socialism is that life is controlled not by the opposition between rich and poor, but by the rank that achievement and talent bestow. That is our freedom, freedom from the economic despotism of the individual".[110] Spengler adopted the anti-English ideas addressed by Plenge and Sombart during World War I that condemned English liberalism and English parliamentarianism while advocating a national socialism that was free from Marxism and that would connect the individual to the state through corporatist organisation.[109] Spengler claimed that socialistic Prussian characteristics existed across Germany, including creativity, discipline, concern for the greater good, productivity and self-sacrifice.[112] He prescribed war as a necessity by saying: "War is the eternal form of higher human existence and states exist for war: they are the expression of the will to war".[113]
The Merwedeplein apartment, where the Frank family lived from 1933 until 1942, remained privately owned until the 2000s. After becoming the focus of a television documentary, the building—in a serious state of disrepair—was purchased by a Dutch housing corporation. Aided by photographs taken by the Frank family and descriptions in letters written by Anne Frank, it was restored to its 1930s appearance. Teresien da Silva of the Anne Frank House and Frank's cousin, Bernhard "Buddy" Elias, contributed to the restoration project. It opened in 2005. Each year, a writer who is unable to write freely in his or her own country is selected for a year-long tenancy, during which they reside and write in the apartment. The first writer selected was the Algerian novelist and poet El-Mahdi Acherchour.[104]
Next to physical labor, military drill played an important part, especially for the older men. Still to-day I can hear the command: 'Eyes right! Eyes front!' The drill consisted mainly of marching in large formations and in turns and practising the salute—a quick removal of the cap. Those who did not greet a passing S.S. man with this procedure laid themselves open to severe punishment. A sixty-five-year-old lawyer, who in spite of glasses could see very little, did not salute a passing 'superior officer,' and was struck so that his glasses were broken. His excuse that he was extremely nearsighted was answered with curses.
In Birkenau, which was built anew on the site of a displaced village, only a small number of historic buildings have survived. Due to the method used in constructing those buildings, planned as temporary structures and erected in a hurry using demolition materials, the natural degradation processes have been accelerating. All efforts are nevertheless being taken to preserve them, strengthen their original fabric and protect them from decay.
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.
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:
^ Andrew Szanajda "The restoration of justice in postwar Hesse, 1945–1949" p. 25 "In practice, it signified intimidating the public through arbitrary psychological terror, operating like the courts of the Inquisition." "The Sondergerichte had a strong deterrent effect during the first years of their operation, since their rapid and severe sentencing was feared."
For the man in charge of Auschwitz, the gas chamber was a welcome innovation. “I had always shuddered at the prospect of carrying out executions by shooting,” commandant Rudolf Höss wrote in a lengthy confession while awaiting execution after the war. “Many members of the Einsatzkommandos, unable to endure wading through blood any longer, had committed suicide. Some had even gone mad.”

On 26 June 1933, Himmler appointed Theodor Eicke commandant of Dachau, who in 1934 was also appointed the first Inspector of Concentration Camps (CCI). In addition, the remaining SA-run camps were taken over by the SS.[14][15][16] Dachau served as both a prototype and a model for the other Nazi concentration camps. Almost every community in Germany had members who were taken there. The newspapers continuously reported on "the removal of the enemies of the Reich to concentration camps" making the general population more aware of their presence. There were jingles warning as early as 1935: "Dear God, make me dumb, that I may not come to Dachau."[17]
