In Nazi Germany, the idea of creating a master race resulted in efforts to "purify" the Deutsche Volk through eugenics and its culmination was the compulsory sterilization or the involuntary euthanasia of physically or mentally disabled people. After World War II, the euthanasia programme was named Action T4.[144] The ideological justification for euthanasia was Hitler's view of Sparta (11th century – 195 BC) as the original Völkisch state and he praised Sparta's dispassionate destruction of congenitally deformed infants in order to maintain racial purity.[145][146] Some non-Aryans enlisted in Nazi organisations like the Hitler Youth and the Wehrmacht, including Germans of African descent[147] and Jewish descent.[148] The Nazis began to implement "racial hygiene" policies as soon as they came to power. The July 1933 "Law for the Prevention of Hereditarily Diseased Offspring" prescribed compulsory sterilization for people with a range of conditions which were thought to be hereditary, such as schizophrenia, epilepsy, Huntington's chorea and "imbecility". Sterilization was also mandated for chronic alcoholism and other forms of social deviance.[149] An estimated 360,000 people were sterilised under this law between 1933 and 1939. Although some Nazis suggested that the programme should be extended to people with physical disabilities, such ideas had to be expressed carefully, given the fact that some Nazis had physical disabilities, one example being one of the most powerful figures of the regime, Joseph Goebbels, who had a deformed right leg.[150]
From its rise to power in 1933, the Nazi regime built a series of incarceration sites to imprison and eliminate so-called "enemies of the state." Most prisoners in the early concentration camps were German Communists, Socialists, Social Democrats, Roma (Gypsies), Jehovah's Witnesses, homosexuals, and persons accused of "asocial" or socially deviant behavior. Some of these facilities were called “concentration camps” because those imprisoned there were physically “concentrated” in one location.
After the war, the Allies occupied Germany, outlawed the Nazi Party and worked to purge its influence from every aspect of German life. The party’s swastika flag quickly became a symbol of evil in modern postwar culture. Although Hitler killed himself before he could be brought to justice, a number of Nazi officials were convicted of war crimes in the Nuremberg trials, which took place in Nuremberg, Germany, from 1945 to 1949.

And for that purpose it is necessary not to think of the camps simply as a hellscape. Reading Wachsmann’s deeply researched, groundbreaking history of the entire camp system makes clear that Dachau and Buchenwald were the products of institutional and ideological forces that we can understand, perhaps all too well. Indeed, it’s possible to think of the camps as what happens when you cross three disciplinary institutions that all societies possess—the prison, the army, and the factory. Over the several phases of their existence, the Nazi camps took on the aspects of all of these, so that prisoners were treated simultaneously as inmates to be corrected, enemies to be combatted, and workers to be exploited. When these forms of dehumanization were combined, and amplified to the maximum by ideology and war, the result was the Konzentrationlager, or K.L.
Our barracks, built for one hundred and fifty men, contained about three hundred and fifty, so that we could not lie on our backs but only on our sides, and could scarcely move without disturbing our neighbors. At half-past six the roll call took place. There were three roll calls a day, one in the morning, one at noon, and a third in the late afternoon. At each roll call we stood at attention, and at least three hours a day were taken up by these roll calls. All except those in the camp hospital had to attend. Some came leaning on the arms of their companions, even men with paralysis who should have been dismissed at once from imprisonment, others with defective feet, and finally those who were unable to move at all and had to be carried. Some among them must have been seriously ill, or else it would hardly have happened that one dropped dead at the roll call—actually dead, for an S. S. man failed in his attempt to revive him by kicks. This 'superior officer' then ordered the comrades of the dead man to close his eyes.
In 1976, Otto Frank took action against Heinz Roth of Frankfurt, who published pamphlets stating that the diary was "a forgery". The judge ruled that if Roth was to publish any further statements he would be subjected to a fine of 500,000 German marks and a six-month jail sentence. Roth appealed against the court's decision. He died in 1978, and after a year his appeal was rejected.[94]
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]

On August 4, 1944, the Gestapo (German Secret State Police) discovered the hiding place. It has been long thought that the authorities acted after being tipped off by an anonymous Dutch caller. But a more recent theory is that the German SD discovered the hiding place by chance, while investigating reports that illegal work and fraud with ration coupons were occurring at the house.

During war, civilians have been concentrated in camps to prevent them from engaging in guerrilla warfare or providing aid to enemy forces or simply as a means of terrorizing the populace into submission. During the South African War (1899–1902) the British confined noncombatants of the republics of Transvaal and Cape Colony in concentration camps. Another instance of interning noncombatant civilians occurred shortly after the outbreak of hostilities between Japan and the United States (December 7, 1941), when more than 100,000 Japanese and Japanese-Americans on the West Coast were taken into custody and placed in camps in the interior.

A Jewish skeleton collection was obtained from among a pool of 115 Jewish Auschwitz inmates, chosen for their perceived stereotypical racial characteristics.[b] Rudolf Brandt and Wolfram Sievers, general manager of the Ahnenerbe (a Nazi research institute), delivered the skeletons to the collection of the Anatomy Institute at the Reichsuniversität Straßburg in Occupied France. The collection was sanctioned by Himmler and under the direction of August Hirt. Ultimately 87 of the inmates were shipped to Natzweiler-Struthof and killed in August 1943.[135] Brandt and Sievers were executed in 1948 after being convicted during the Doctors' trial, part of the Subsequent Nuremberg trials.[136]
Auschwitz didn’t long remain a camp exclusively for Poles. In June 1941, Germany launched a surprise invasion of the Soviet Union, taking three million prisoners over the next seven months. Many were starved to death. Others were sent to occupied Poland or Germany as slave laborers. In the fall of 1941, ten thousand prisoners of war arrived at Auschwitz and began building the Birkenau camp.
Between 1942 and 1944, the SS authorities at Auschwitz established 44 subcamps. Some of them were established within the officially designated “development” zone, including Budy, Rajsko, Tschechowitz, Harmense, and Babitz. Others, such as Blechhammer, Gleiwitz, Althammer, Fürstengrube, Laurahuette, and Eintrachthuette were located in Upper Silesia north and west of the Vistula River. Some subcamps, such as Freudenthal and Bruenn (Brno), were located in Moravia.

Radical Antisemitism was promoted by prominent advocates of Völkisch nationalism, including Eugen Diederichs, Paul de Lagarde and Julius Langbehn.[69] De Lagarde called the Jews a "bacillus, the carriers of decay ... who pollute every national culture ... and destroy all faiths with their materialistic liberalism" and he called for the extermination of the Jews.[89] Langbehn called for a war of annihilation against the Jews, and his genocidal policies were later published by the Nazis and given to soldiers on the front during World War II.[89] One antisemitic ideologue of the period, Friedrich Lange, even used the term "National Socialism" to describe his own anti-capitalist take on the Völkisch nationalist template.[90]

This complex incorporated 45 forced labor sub-camps. The name Buna was based on the Buna synthetic rubber factory on site, owned by I.G. Farben, Germany’s largest chemical company. Most workers at this and other German-owned factories were Jewish inmates. The labor would push inmates to the point of total exhaustion, at which time new laborers replaced them.
On the two occasions I have returned to Auschwitz, in 1995 and 2011, although I haven’t got memories as such of the time I spent there, something is triggered deep inside me, both physically and in my inner being. I get very nervous and the death, the cold, the expanse and the emptiness of it swamps me – it’s a feeling that it’s hard to explain but it’s everywhere. I can feel the burnt earth everywhere I walk.

One exchange Jew was Eve, daughter of Hans and Rita Oppenheimer. The family was German–Jewish. Eve’s father had moved to Holland from Germany to escape Nazi persecution. Eve was born in June 1936 during a visit to England by her mother and brothers, Paul and Rudi; she therefore had British nationality. The mother, brothers and sister then joined the father in Holland.

When it came to power in 1933, the Nazi Party had over 2 million members. In 1939, the membership total rose to 5.3 million with 81% being male and 19% being female. It continued to attract many more and by 1945 the party reached its peak of 8 million with 63% being male and 37% being female (about 10% of the German population of 80 million).[2][116]
In the early years of the regime, Germany was without allies, and its military was drastically weakened by the Versailles Treaty. France, Poland, Italy, and the Soviet Union each had reasons to object to Hitler's rise to power. Poland suggested to France that the two nations engage in a preventive war against Germany in March 1933. Fascist Italy objected to German claims in the Balkans and on Austria, which Benito Mussolini considered to be in Italy's sphere of influence.[52]
From 1942, the SS reorganised the concentration camp administration to mobilise the millions of prisoners within the camps. The Nazis established hundreds of sub-camps across Europe. The Auschwitz camp complex contained over 40 sub-camps that housed thousands of Jewish prisoners to work as forced labour in the coalmines, various munitions factories and the I.G. Farben synthetic rubber plant at Buna Monovitz.
Nazism is a form of fascism and showed that ideology's disdain for liberal democracy and the parliamentary system, but also incorporated fervent antisemitism, scientific racism, and eugenics into its creed. Its extreme nationalism came from Pan-Germanism and the Völkisch movement prominent in the German nationalism of the time, and it was strongly influenced by the anti-Communist Freikorps paramilitary groups that emerged after Germany's defeat in World War I, from which came the party's "cult of violence" which was "at the heart of the movement."[2]
In October 1941, work began on Auschwitz II, or Birkenau, located outside the nearby village of Brzezinka. There the SS later developed a huge concentration camp and extermination complex that included some 300 prison barracks; four large so-called Badeanstalten (German: “bathhouses”), in which prisoners were gassed to death; Leichenkeller (“corpse cellars”), in which their bodies were stored; and Einäscherungsöfen (“cremating ovens”). Another camp (Buna-Monowitz), near the village of Dwory, later called Auschwitz III, became in May 1942 a slave-labour camp supplying workers for the nearby chemical and synthetic-rubber works of IG Farben. In addition, Auschwitz became the nexus of a complex of 45 smaller subcamps in the region, most of which housed slave labourers. During most of the period from 1940 to 1945, the commandant of the central Auschwitz camps was SS-Hauptsturmführer (Capt.) and ultimately SS-Obersturmbannführer (Lieut. Col.) Rudolf Franz Hoess (Höss).

In chambers II and III, the killings took place in underground rooms, and the corpses were carried to the five ovens by an electrically operated lift. Before cremation gold teeth and any other valuables, such as rings, were removed from the corpses. In IV and V the gas chambers and ovens were on the same level, but the ovens were so poorly built and the usage was so great that they repeatedly malfunctioned and had to be abandoned. The corpses were finally burned outside, in the open, as in 1943. Jewish Sonderkommandos worked the crematoria under SS supervision.

Historian Michael Burleigh claims that Nazism used Christianity for political purposes, but such use required that "fundamental tenets were stripped out, but the remaining diffuse religious emotionality had its uses".[215] Burleigh claims that Nazism's conception of spirituality was "self-consciously pagan and primitive".[215] However, historian Roger Griffin rejects the claim that Nazism was primarily pagan, noting that although there were some influential neo-paganists in the Nazi Party, such as Heinrich Himmler and Alfred Rosenberg, they represented a minority and their views did not influence Nazi ideology beyond its use for symbolism. It is noted that Hitler denounced Germanic paganism in Mein Kampf and condemned Rosenberg's and Himmler's paganism as "nonsense".[216]
To complete this mission, Hitler ordered the construction of death camps. Unlike concentration camps, which had existed in Germany since 1933 and were detention centers for Jews, political prisoners and other perceived enemies of the Nazi state, death camps existed for the sole purpose of killing Jews and other “undesirables,” in what became known as the Holocaust.
Eventually, Birkenau held the majority of prisoners in the Auschwitz complex, including Jews, Poles, Germans, and Gypsies. Furthermore, it maintained the most degrading and inhumane conditions–inclusive of the complex’s gas chambers and crematoria. A third section, Auschwitz III, was constructed in nearby Monowitz, and consisted of a forced labor camp called Buna-Monowitz.
By the time the Germans invaded Poland in September 1939, unleashing World War II, there were six concentration camps in the so-called Greater German Reich: Dachau (founded 1933), Sachsenhausen (1936), Buchenwald (1937), Flossenbürg in northeastern Bavaria near the 1937 Czech border (1938), Mauthausen, near Linz, Austria (1938), and Ravensbrück, the women's camp, established in Brandenburg Province, southeast of Berlin (1939), after the dissolution of Lichtenburg.

In most of the camps discovered by the Soviets, almost all the prisoners had already been removed, leaving only a few thousand alive—7,000 inmates were found in Auschwitz, including 180 children who had been experimented on by doctors.[45] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division,[46] 13,000 corpses lay unburied, and another 10,000 died from typhus or malnutrition over the following weeks.[47] The British forced the remaining SS guards to gather up the corpses and place them in mass graves.[48]
