The twin pairs of gas chambers were numbered II and III, and IV and V. The first opened on March 31, 1943, the last on April 4, 1943. The total area of the gas chambers was 2,255 square meters; the capacity of these crematoria was 4,420 people. Those selected to die were undressed in the undressing room and then pushed into the gas chambers. It took about 20 minutes for all the people to death. In 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.
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]
That month, Himmler ordered the evacuation of all camps, charging camp commanders with "making sure that not a single prisoner from the concentration camps falls alive into the hands of the enemy".[240] Beginning on 17 January, 56,000–58,000 Auschwitz detainees—over 20,000 from Auschwitz I and II, over 30,000 from subcamps, and two-thirds of them Jews—were evacuated under guard, largely on foot, in severe winter conditions, heading west.[241][242] Around 2,200 were evacuated by rail from two subcamps; fewer than 9,000 were left behind, deemed too sick to move.[243] During the marches, camp staff shot anyone too sick or exhausted to continue, or anyone stopping to urinate or tie a shoelace. SS officers walked behind the marchers killing anyone lagging behind who had not already been shot.[235] Peter Longerich estimates that a quarter of the detainees were thus killed.[236] Those who managed to walk to Wodzisław Śląski and Gliwice were sent on open freight cars, without food, to concentration camps in Germany: Bergen-Belsen, Buchenwald, Dachau, Flossenburg, Gross-Rosen, Mauthausen, Dora-Mittelbau, Ravensbruck, and Sachsenhausen.[244]
The prisoners’ camp routine consisted of many duties. The daily schedule included waking at dawn, straightening one’s sleep area, morning roll call, the trip to work, long hours of hard labor, standing in line for a pitiful meal, the return to camp, block inspection, and evening roll call. During roll call, prisoners were made to stand completely motionless and quiet for hours, in extremely thin clothing, irrespective of the weather. Whoever fell or even stumbled was killed. Prisoners had to focus all their energy merely on surviving the day’s tortures.
Under Nazi rule, all other political parties were banned. In 1933, the Nazis opened their first concentration camp, in Dachau, Germany, to house political prisoners. Dachau evolved into a death camp where countless thousands of Jews died from malnutrition, disease and overwork or were executed. In addition to Jews, the camp’s prisoners included members of other groups Hitler considered unfit for the new Germany, including artists, intellectuals, Gypsies, the physically and mentally handicapped and homosexuals.
Though we tend to think of Hitler’s Germany as a highly regimented dictatorship, in practice Nazi rule was chaotic and improvisatory. Rival power bases in the Party and the German state competed to carry out what they believed to be Hitler’s wishes. This system of “working towards the Fuhrer,” as it was called by Hitler’s biographer Ian Kershaw, was clearly in evidence when it came to the concentration camps. The K.L. system, during its twelve years of existence, included twenty-seven main camps and more than a thousand subcamps. At its peak, in early 1945, it housed more than seven hundred thousand inmates. In addition to being a major penal and economic institution, it was a central symbol of Hitler’s rule. Yet Hitler plays almost no role in Wachsmann’s book, and Wachsmann writes that Hitler was never seen to visit a camp. It was Heinrich Himmler, the head of the S.S., who was in charge of the camp system, and its growth was due in part to his ambition to make the S.S. the most powerful force in Germany.

After the liquidation of the Polish state and its institutions, the fundamental goal of German policy in occupied Poland was the exploitation of material and labor resources, and the removal of the local Polish population and ethnic minorities. This was done through expulsion and systematic extermination. The Polish lands were to be completely germanized, through German settlement in the depopulated area.

With its sections separated by barbed-wire fences, Auschwitz II had the largest prisoner population of any of the three main camps. In January 1942, the first chamber using lethal Zyklon B gas was built on the camp. This building was judged inadequate for killing on the scale the Nazis wanted, and four further chambers were built. These were used for systematic genocide right up until November 1944, two months before the camp was liberated.
Probably my earliest memories of anything at all are of walking through the streets of Trenčín and people stopping in their tracks and saying with amazement: “You’re back!” “What a miracle that you’re alive!” I understood as a three-and-a-half to four-year-old that I was a miracle because I got to hear it so many times, but I didn’t really understand what the word meant. Only much later could I recognise what a miracle it really was that I had survived, when I learned that of the thousands of Slovak men and women who were deported to Auschwitz, only a few hundred returned.

A total of 22 main concentration camps (Stamlager) were established, together with approximately 1,200 affiliate camps. Besides these, thousands of smaller camps existed in all parts of German-controlled Europe. The 22 main camps, in alphabetical order, were as follows: Arbeitsdorf, Auschwitz, Bergen-Belsen, Buchenwald, Dachau, Flossenbürg, Gross-Rosen, Herzogenbosch, Kaunas, Krakow-Plaszow, Majdanek, Mauthausen, Mittelbau-Dora, Natzweiler-Struthof, Neuengamme, Ravensbrück, Riga-Kaiserwald, Sachsenhausen, Stutthof, Vaivara, Warsaw, Wewelsburg, Germany.
The soldiers also found warehouses containing 836,525 items of women clothing, 348,820 items of men clothing, 43,525 pairs of shoes and vast numbers of toothbrushes, glasses and other personal effects. They found also 460 artificial limbs and seven tons of human hair shaved from Jews before they were murdered. The human hairs were used by the company “Alex Zink” (located in Bavaria) for confection of cloth. This company was paying the Nazi’s 50 pfennig per kilo of human hair.

Of those who received numbers at Auschwitz-Birkenau, only 65,000 survived. It is estimated that only about 200,000 people who passed through the Auschwitz camps survived. Michael Bornstein was one of the lucky ones. Decades after the war, he learned from Auschwitz documents kept in Israel that he had survived because he was sick and the Nazis left him behind when they evacuated the camp. He said that he was one of only 52 children under the age of eight who lived.
The first mass transport to Auschwitz I, which included Catholic prisoners, suspected members of the Polish resistance, and 20 Jews, arrived on 14 June 1940 from prison in Tarnów, Poland. They were interned in the former building of the Polish Tobacco Monopoly, adjacent to the site, until the camp was ready.[24] By the end of 1940, the SS had confiscated land around the camp to create a 40-square-kilometre (15 sq mi) "zone of interest" surrounded by a double ring of electrified barbed wire fences and watchtowers.[25] The inmate population grew quickly as the camp absorbed Poland's intelligentsia and dissidents. By March 1941, 10,900 were imprisoned there, most of them Poles.[22]

Nazism attempted to reconcile conservative, nationalist ideology with a socially radical doctrine. In so doing, it became a profoundly revolutionary movement—albeit a largely negative one. Rejecting rationalism, liberalism, democracy, the rule of law, human rights, and all movements of international cooperation and peace, it stressed instinct, the subordination of the individual to the state, and the necessity of blind and unswerving obedience to leaders appointed from above. It also emphasized the inequality of men and races and the right of the strong to rule the weak; sought to purge or suppress competing political, religious, and social institutions; advanced an ethic of hardness and ferocity; and partly destroyed class distinctions by drawing into the movement misfits and failures from all social classes. Although socialism was traditionally an internationalist creed, the radical wing of Nazism knew that a mass base existed for policies that were simultaneously anticapitalist and nationalist. However, after Hitler secured power, this radical strain was eliminated.

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]

During the next two months, some fifty thousand people were arrested on this basis, in what turned into a “frenzy” of political purges and score-settling. In the legal murk of the early Nazi regime, it was unclear who had the power to make such arrests, and so it was claimed by everyone: national, state, and local officials, police and civilians, Party leaders. “Everybody is arresting everybody,” a Nazi official complained in the summer of 1933. “Everybody threatens everybody with Dachau.” As this suggests, it was already clear that the most notorious and frightening destination for political detainees was the concentration camp built by Himmler at Dachau, in Bavaria. The prisoners were originally housed in an old munitions factory, but soon Himmler constructed a “model camp,” the architecture and organization of which provided the pattern for most of the later K.L. The camp was guarded not by police but by members of the S.S.—a Nazi Party entity rather than a state force.

The United States is a nation with two radically different ideas at its heart: white supremacy and equality under the law. A nation that currently has more immigrants than any country in the world but is undergoing traumatic convulsions at the very mention of immigrants. A nation with a pessimistic mind and an optimistic soul, founded and codified by white men, whose geographic expansion was made possible by the violent clearing out of the original inhabitants, whose economic growth was purchased through slavery, but also a land where millions of immigrants have come in search of work and opportunity. The question of who counts in the “we” and who belongs to the “them” is being argued and fought every day, from the courtroom to the classroom to the streets. It is a conversation that has been taking place since the founding of the United States, and one that was taking place in Germany when the Nazi cabal seized the state. How this nation answers that question will determine which of the two American ideas lives on.
Nazi Germany maintained concentration camps (German: Konzentrationslager, KZ or KL) throughout the territories it controlled before and during the Second World War. The first Nazi camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control of the police by Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring.[2] Used to hold and torture political opponents and union organizers, the camps initially held around 45,000 prisoners.[3] In 1933–1939, before the onset of war, most prisoners consisted of German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans.[4]
