Some of the most notorious slave labour camps included a network of subcamps. Gross-Rosen had 100 subcamps,[37] Auschwitz had 44 subcamps,[38][38][39] Stutthof had 40 sub-camps set up contingently.[40] Prisoners in these subcamps were dying from starvation, untreated disease and summary executions by the tens of thousands already since the beginning of war.[41]
By the end of the war, the number of people who had died in the concentration camps, from all causes—starvation, sickness, exhaustion, beating, shooting, gassing—was more than eight hundred thousand. The figure does not include the hundreds of thousands of Jews gassed on arrival at Auschwitz. If the K.L. were indeed a battlefront, as the Death’s-Head S.S. liked to believe, the deaths, in the course of twelve years, roughly equalled the casualties sustained by the Axis during the Battle of Stalingrad, among the deadliest actual engagements of the war. But in the camps the Nazis fought against helpless enemies. Considered as prisons, too, the K.L. were paradoxical: it was impossible to correct or rehabilitate people whose very nature, according to Nazi propaganda, was criminal or sick. And as economic institutions they were utterly counterproductive, wasting huge numbers of lives even as the need for workers in Germany became more and more acute.
For her thirteenth birthday on 12 June 1942, Frank received a book she had shown her father in a shop window a few days earlier. Although it was an autograph book, bound with red-and-white checkered cloth[17] and with a small lock on the front, Frank decided she would use it as a diary,[18] and she began writing in it almost immediately. In her entry dated 20 June 1942, she lists many of the restrictions placed upon the lives of the Dutch Jewish population.[19]
The Nazis intended on deporting all Romani people from Germany, and confined them to Zigeunerlager (Gypsy camps) for this purpose. Himmler ordered their deportation from Germany in December 1942, with few exceptions. A total of 23,000 Romani were deported to Auschwitz concentration camp, of whom 19,000 died. Outside of Germany, the Romani people were regularly used for forced labour, though many were killed. In the Baltic states and the Soviet Union, 30,000 Romani were killed by the SS, the German Army, and Einsatzgruppen. In occupied Serbia, 1,000 to 12,000 Romani were killed, while nearly all 25,000 Romani living in the Independent State of Croatia were killed. The estimates at end of the war put the total death toll at around 220,000, which equalled approximately 25 percent of the Romani population in Europe.[311]
By August 1944 there were 105,168 prisoners in Auschwitz whilst another 50,000 Jewish prisoners lived in Auschwitz’s satellite camps. The camp’s population grew constantly, despite the high mortality rate caused by exterminations, starvation, hard labor, and contagious diseases. Upon arrival at the platform in Birkenau, Jews were thrown out of their train cars without their belongings and forced to form two lines, men and women separately.
The Nazi regime promoted a liberal code of conduct regarding sexual matters and was sympathetic to women who bore children out of wedlock.[382] Promiscuity increased as the war progressed, with unmarried soldiers often intimately involved with several women simultaneously. Soldier's wives were frequently involved in extramarital relationships. Sex was sometimes used as a commodity to obtain better work from a foreign labourer.[383] Pamphlets enjoined German women to avoid sexual relations with foreign workers as a danger to their blood.[384]
In addition to the Nazi Party proper, several paramilitary groups existed which "supported" Nazi aims. All members of these paramilitary organisations were required to become regular Nazi Party members first and could then enlist in the group of their choice. An exception was the Waffen-SS, considered the military arm of the SS and Nazi Party, which during the Second World War allowed members to enlist without joining the Nazi Party. Foreign volunteers of the Waffen-SS were also not required to be members of the Nazi Party, although many joined local nationalist groups from their own countries with the same aims. Police officers, including members of the Gestapo, frequently held SS rank for administrative reasons (known as "rank parity") and were likewise not required to be members of the Nazi Party.

Röhm hoped to assume command of the army and absorb it into the ranks of the SA.[230] Hindenburg and Defence Minister Werner von Blomberg threatened to impose martial law if the activities of the SA were not curtailed.[231] Therefore, less than a year and a half after seizing power, Hitler ordered the deaths of the SA leadership, including Rohm. After the purge of 1934, the SA was no longer a major force.[38]

Created by the Government of Poland in 1947 at the request of survivors, the Auschwitz-Birkenau State Museum comprises almost 472 acres (191 hectares) and was declared a World Heritage Site by UNESCO in 1979. The Memorial today consists of Collections, Archives, a research, education, conservation and publishing center. Millions of people have visited the complex to learn its crucial significance, honor survivors and victims, and carry forward the memory of Auschwitz and the Holocaust.

The first party that attempted to combine nationalism and socialism was the (Austria-Hungary) German Workers' Party, which predominantly aimed to solve the conflict between the Austrian Germans and the Czechs in the multi-ethnic Austrian Empire, then part of Austria-Hungary.[70] In 1896 the German politician Friedrich Naumann formed the National-Social Association which aimed to combine German nationalism and a non-Marxist form of socialism together; the attempt turned out to be futile and the idea of linking nationalism with socialism quickly became equated with antisemites, extreme German nationalists and the Völkisch movement in general.[27]
Although the Germans destroyed parts of the camps before abandoning them in 1945, much of Auschwitz I and Auschwitz II (Birkenau) remained intact and were later converted into a museum and memorial. The site has been threatened by increased industrial activity in Oświęcim. In 1996, however, the Polish government joined with other organizations in a large-scale effort to ensure its preservation. Originally named Auschwitz Concentration Camp, the memorial was designated a UNESCO World Heritage site in 1979. It was renamed “Auschwitz-Birkenau. The Nazi German Concentration and Extermination Camp (1940–1945)” in 2007.
Initially the new facilities were "underutilized". From April 1943 to March 1944, "only" 160,000 Jews were killed at Birkenau, but from March 1944 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.
I worked out pretty quickly certain survival tricks. That if the guards called us to line up in front of the barracks, I should hide or sneak into another barracks. The safest place I could find to hide was in the yard near the bathrooms where all the dead bodies were brought and piled up … I would get on the pile, lie down next to the dead bodies and pretend I was one of them.
Later that evening we were lined up at the outskirts of the camp, while trucks, arriving constantly, brought new inmates who suffered the same reception as we had before them. After the collective defamation the individual ones began. The camp commander, Baranowsky, a stocky, common-looking man with the insignia of a high rank in the S.S., passed along our rows with his staff. He addressed some, asked their profession, and, in the case of former officials, inquired the amount of their pension, usually commenting that it was too high, especially for a Jew. Arrivals who stood out because of some physical defect were especially ridiculed by him and his staff. Some men wore hearing aids that connected the ear through a wire with a microphone. These were torn out of the ear with rude force, and afterwards inspected by the whole staff as something incredibly strange.
I threw myself into family life. I married young, I had three children, (I now also have four grandchildren) and then I went to college and became a teacher. You fall into a routine and do the best you can. But I’ve never lost the feeling of how unreliable human beings are and neither am I fooled by superficial civilisation. But I realise that loss of faith in people is more devastating than loss of faith in God.
The K.L. was defined from the beginning by its legal ambiguity. The camps were outside ordinary law, answerable not to judges and courts but to the S.S. and Himmler. At the same time, they were governed by an extensive set of regulations, which covered everything from their layout (including decorative flower beds) to the whipping of prisoners, which in theory had to be approved on a case-by-case basis by Himmler personally. Yet these regulations were often ignored by the camp S.S.—physical violence, for instance, was endemic, and the idea that a guard would have to ask permission before beating or even killing a prisoner was laughable. Strangely, however, it was possible, in the prewar years, at least, for a guard to be prosecuted for such a killing. In 1937, Paul Zeidler was among a group of guards who strangled a prisoner who had been a prominent churchman and judge; when the case attracted publicity, the S.S. allowed Zeidler to be charged and convicted. (He was sentenced to a year in jail.)
The Reichskulturkammer (Reich Chamber of Culture) was organised under the control of the Propaganda Ministry in September 1933. Sub-chambers were set up to control aspects of cultural life such as film, radio, newspapers, fine arts, music, theatre and literature. Members of these professions were required to join their respective organisation. Jews and people considered politically unreliable were prevented from working in the arts, and many emigrated. Books and scripts had to be approved by the Propaganda Ministry prior to publication. Standards deteriorated as the regime sought to use cultural outlets exclusively as propaganda media.[455]
Sunday was not a work day, but prisoners were required to clean the barracks and take their weekly shower,[115] and were allowed to write (in German) to their families, although the SS censored the outgoing mail. Inmates who did not speak German would trade some of their bread for help composing their letters.[116] Observant Jews tried to keep track of the Hebrew calendar and Jewish holidays, including Shabbat, and the weekly Torah portion. No watches, calendars, or clocks were permitted in the camp. Jewish calendars were rare among prisoners; being in possession of one was dangerous. Only two Jewish calendars made in Auschwitz survived to the end of the war. Prisoners kept track of the days in other ways, such as obtaining information from newcomers.[117]

Sessions’s characterization falls into a nether region between truth and falsehood. Perhaps his is the best comment to begin with precisely because it is a half-truth. Yes, after 1941, concentration camps held Jews to prevent them from leaving Germany — but also to consolidate them for extermination. However, for more than eight years earlier, the camps generally were used for the opposite purpose: to force Jews to emigrate from Germany by making life intolerable, in part by separating men from their families. This is precisely the kind of important historical nuance lost in the hysteria surrounding Trump’s callous immigration policy. There are valuable comparisons to be made, but they must be historically informed.
Frank soon found the traction to publish Margot, a novel that imagined her sister living the life she once dreamed of, as a midwife in the Galilee. A surreal work that breaks the boundaries between novel and memoir, and leaves ambiguous which of its characters are dead or alive, Margot became wildly popular in Israel. Its English translation allowed Frank to find a small but appreciative audience in the United States.
But individual deaths, by sickness or violence, were not enough to keep the number of prisoners within manageable limits. Accordingly, in early 1941 Himmler decided to begin the mass murder of prisoners in gas chambers, building on a program that the Nazis had developed earlier for euthanizing the disabled. Here, again, the camps’ sinister combination of bureaucratic rationalism and anarchic violence was on display. During the following months, teams of S.S. doctors visited the major camps in turn, inspecting prisoners in order to select the “infirm” for gassing. Everything was done with an appearance of medical rigor. The doctors filled out a form for each inmate, with headings for “Diagnosis” and “Incurable Physical Ailments.” But it was all mere theatre. Helm’s description of the visit of Dr. Friedrich Mennecke to Ravensbrück, in November, 1941, shows that inspections of prisoners—whom he referred to in letters home as “forms” or “portions”—were cursory at best, with the victims parading naked in front of the doctors at a distance of twenty feet. (Jewish prisoners were automatically “selected,” without an examination.) In one letter, Mennecke brags of having disposed of fifty-six “forms” before noon. Those selected were taken to an undisclosed location for gassing; their fate became clear to the remaining Ravensbrück prisoners when the dead women’s clothes and personal effects arrived back at the camp by truck.
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]
Edith Frank died of starvation at Auschwitz in January 1945. Hermann van Pels died in the gas chambers at Auschwitz soon after his arrival there in 1944; his wife is believed to have likely died at the Theresienstadt concentration camp in what is now the Czech Republic in the spring of 1945. Peter van Pels died at the Mauthausen concentration camp in Austria in May 1945. Fritz Pfeffer died from illness in late December 1944 at the Neuengamme concentration camp in Germany. Anne Frank’s father, Otto, was the only member of the group to survive; he was liberated from Auschwitz by Soviet troops on January 27, 1945.
Although he opposed communist ideology, Hitler publicly praised the Soviet Union's leader Joseph Stalin and Stalinism on numerous occasions.[57] Hitler commended Stalin for seeking to purify the Communist Party of the Soviet Union of Jewish influences, noting Stalin's purging of Jewish communists such as Leon Trotsky, Grigory Zinoviev, Lev Kamenev and Karl Radek.[58] While Hitler had always intended to bring Germany into conflict with the Soviet Union so he could gain Lebensraum ("living space"), he supported a temporary strategic alliance between Nazi Germany and the Soviet Union to form a common anti-liberal front so they could defeat liberal democracies, particularly France.[57]
Peterson, who is researching the long history of the Rivesaltes camp, also told me that the camp remained more or less in operation from 1939 through 1967 and then after 1985. Prisoners and refugees after the war included POWs, collaborators, Algerians and, in the 1980s, migrants waiting to be expelled from the country. The French government did little in the meantime to improve facilities from their wartime conditions.
The Hitler cabinet used the terms of the Reichstag Fire Decree and later the Enabling Act to initiate the process of Gleichschaltung ("co-ordination"), which brought all aspects of life under party control.[25] Individual states not controlled by elected Nazi governments or Nazi-led coalitions were forced to agree to the appointment of Reich Commissars to bring the states in line with the policies of the central government. These Commissars had the power to appoint and remove local governments, state parliaments, officials, and judges. In this way Germany became a de facto unitary state, with all state governments controlled by the central government under the NSDAP.[26][27] The state parliaments and the Reichsrat (federal upper house) were abolished in January 1934,[28] with all state powers being transferred to the central government.[27]

In January 1934, Germany signed a non-aggression pact with Poland.[73] In March 1939, Hitler demanded the return of the Free City of Danzig and the Polish Corridor, a strip of land that separated East Prussia from the rest of Germany. The British announced they would come to the aid of Poland if it was attacked. Hitler, believing the British would not actually take action, ordered an invasion plan should be readied for September 1939.[74] On 23 May, Hitler described to his generals his overall plan of not only seizing the Polish Corridor but greatly expanding German territory eastward at the expense of Poland. He expected this time they would be met by force.[75]

Six million people were unemployed when the Nazis took power in 1933 and by 1937 there were fewer than a million.[263] This was in part due to the removal of women from the workforce.[264] Real wages dropped by 25 percent between 1933 and 1938.[251] After the dissolution of the trade unions in May 1933, their funds were seized and their leadership arrested,[265] including those who attempted to co-operate with the NSDAP.[30] A new organisation, the German Labour Front, was created and placed under NSDAP functionary Robert Ley.[265] The average work week was 43 hours in 1933; by 1939 this increased to 47 hours.[266]
After Germany's annexation of Austria in March 1938, the Nazis arrested German and Austrian Jews and imprisoned them in the Dachau, Buchenwald, and Sachsenhausen concentration camps, all located in Germany. Following the violent Kristallnacht ("Night of Broken Glass") pogroms in November 1938, the Nazis conducted mass arrests of adult male Jews and incarcerated them in camps for brief periods.
Many scholars think Nazism was a form of far-right politics.[1] Nazism is a form of fascism and uses biological racism and antisemitism. Much of the philosophy of this movement was based on an idea that the 'Aryan race', the term they used for what we today call Germanic people, was better than all other races, and had the greatest ability to survive. According to the racist and ableist ideas of Nazism, the Germanic peoples were the Herrenvolk (master race).[2] The 'inferior' races and people - the Jews, Roma people, Slavs, disabled and blacks - were classified as Untermenschen (sub-humans).[3]
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.
Jewish deportees arriving at Auschwitz-Birkenau immediately underwent selection. The SS staff chose some of the able-bodied for forced labor and sent the rest directly to the gas chambers, which were disguised as shower installations to mislead the victims. The belongings of all deportees were confiscated and sorted in the "Kanada" (Canada) warehouse for shipment back to Germany. Canada symbolized wealth to the prisoners.

Auschwitz I, a former Polish army barracks, was the main camp (Stammlager) and administrative headquarters of the camp complex. Intending to use it to house political prisoners, Reichsführer-SS Heinrich Himmler, head of the Schutzstaffel (SS), approved the site in April 1940 on the recommendation of SS-Obersturmbannführer (lieutenant colonel) Rudolf Höss, then of the Concentration Camps Inspectorate. Höss oversaw the development of the camp and served as its first commandant, with SS-Obersturmführer (senior lieutenant) Josef Kramer as his deputy.[21] Around 1,000 m long and 400 m wide,[22] Auschwitz I consisted of 20 brick buildings, six of them two-story; a second story was added to the others in 1943 and eight new blocks were built.[23] The camp housed the SS barracks and by 1943 held 30,000 inmates.[22] The first 30 prisoners arrived on 20 May 1940 after being transported from the Sachsenhausen concentration camp in Oranienburg, Germany. Convicted German criminals (Berufsverbrecher), the men were known as "greens" after the green triangles they were required to wear on their prison clothing. Brought to the camp as functionaries, this group did much to establish the sadism of early camp life, which was directed particularly at Polish inmates, until the political prisoners began to take over their roles.[4]
The concentration camps make sense only if they are understood as products not of reason but of ideology, which is to say, of fantasy. Nazism taught the Germans to see themselves as a beleaguered nation, constantly set upon by enemies external and internal. Metaphors of infection and disease, of betrayal and stabs in the back, were central to Nazi discourse. The concentration camp became the place where those metaphorical evils could be rendered concrete and visible. Here, behind barbed wire, were the traitors, Bolsheviks, parasites, and Jews who were intent on destroying the Fatherland.
Fewer than 200 Jews escaped from the camps. Herman Shine, one of the last survivors to have escaped Auschwitz, died in July 2018. He was born in Berlin to a Polish father and they were arrested in that city in 1939. Along with 1,700 other Polish Jews, they were deported to Sachsenhausen. To survive, Shine claimed to be a roofer and learned how to build roofs before being transferred to Auschwitz in 1942.
The camp Stos first saw, some 20 brick buildings, was a run-down former Polish artillery barrack the Nazis had taken over a few months before. Many Poles followed Stos to Auschwitz; few were as lucky. In its original incarnation as a concentration camp, Auschwitz was designed to work inmates to death. At first, most of the labor helped expand the camp itself; other work, such as gravel mining and farming, earned money for the SS. The Nazis even had a term for it, Vernichtung durch Arbeit (“Destruction through work”). The notorious SS camp supervisor Karl Fritzsch greeted new arrivals with a speech: “You have arrived here not at a sanatorium, but at a German concentration camp, from which the only exit is through the chimney of its crematorium.”
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]
Soon afterwards, the gas chambers and crematoria were destroyed on Himmler's orders, since the regime wanted to hide the traces of its murdering machine ahead of the advancing Red Army. As Soviet troops came near to the camp in January 1945, it was hurriedly evacuated and 58 000 prisoners were driven out on a death march, during which most were killed. On the 27th of January 1945, the Red Army entered the camp (link in Czech). They found 7 650 exhausted and starving prisoners and a number of pieces of evidence of crimes that the Nazis had not had time to destroy. In the camp stores they found almost eight tonnes of human hair and over a million men's suits and women's dresses.
One of the first people I encountered was Mengele. He told us to undress and stand in line and he went through the ranks deciding who was strong and healthy and fit for work, and who was only fit for the gas chamber. After inspecting me, he put his thumb up high, so they gave me the striped uniform and sent me to get a number tattooed on to my arm. I don’t remember the number. It’s there still, but I never look at it because it brings back too many painful memories.
What is troubling about Hitler’s American Model—though Whitman never mentions it—is how closely the events of the 1930s mirror our own. Such statements are bound to seem exaggerated. But even by the early 1930s, Germany was not destined to arrive at catastrophe. The ideas in the air at the time, including anti-Semitism specifically, are still the object of white nationalist fantasy today. What is most alarming is an unstated implication of Whitman’s thesis: if U.S. racism, anti-immigrant hostility, and third-class citizenship influenced the Nazi regime, then remnants of such influence must still exist today. Indeed, they appear to be resurgent.
On 5 January 1919, Drexler created a new political party and proposed it should be named the "German Socialist Workers' Party", but Harrer objected to the term "socialist"; so the term was removed and the party was named the German Workers' Party (Deutsche Arbeiterpartei, DAP).[29] To ease concerns among potential middle-class supporters, Drexler made clear that unlike Marxists the party supported the middle-class and that its socialist policy was meant to give social welfare to German citizens deemed part of the Aryan race.[25] They became one of many völkisch movements that existed in Germany. Like other völkisch groups, the DAP advocated the belief that through profit-sharing instead of socialisation Germany should become a unified "people's community" (Volksgemeinschaft) rather than a society divided along class and party lines.[30] This ideology was explicitly antisemitic. As early as 1920, the party was raising money by selling a tobacco called Anti-Semit.[31]
At the bottom of the K.L. hierarchy, even below the criminals, were the Jews. Today, the words “concentration camp” immediately summon up the idea of the Holocaust, the genocide of European Jews by the Nazis; and we tend to think of the camps as the primary sites of that genocide. In fact, as Wachsmann writes, as late as 1942 “Jews made up fewer than five thousand of the eighty thousand KL inmates.” There had been a temporary spike in the Jewish inmate population in November, 1938, after Kristallnacht, when the Nazis rounded up tens of thousands of Jewish men. But, for most of the camps’ first decade, Jewish prisoners had usually been sent there not for their religion, per se, but for specific offenses, such as political dissent or illicit sexual relations with an Aryan. Once there, however, they found themselves subject to special torments, ranging from running a gantlet of truncheons to heavy labor, like rock-breaking. As the chief enemies in the Nazi imagination, Jews were also the natural targets for spontaneous S.S. violence—blows, kicks, attacks by savage dogs.
During the Röhm Purge of 30 June to 2 July 1934 (also known as the "Night of the Long Knives"), Hitler disempowered the SA's leadership—most of whom belonged to the Strasserist (national revolutionary) faction within the NSDAP—and ordered them killed. He accused them of having conspired to stage a coup d'état, but it is believed that this was only a pretence to justify the suppression of any intraparty opposition. The purge was executed by the SS, assisted by the Gestapo and Reichswehr units. Aside from Strasserist Nazis, they also murdered anti-Nazi conservative figures like former chancellor Kurt von Schleicher.[84] After this, the SA continued to exist but lost much of its importance, while the role of the SS grew significantly. Formerly only a sub-organisation of the SA, it was made into a separate organisation of the NSDAP in July 1934.[85]
On the morning of 4 August 1944, the Achterhuis was stormed by a group of German uniformed police (Grüne Polizei) led by SS-Oberscharführer Karl Silberbauer of the Sicherheitsdienst.[37] The Franks, van Pelses, and Pfeffer were taken to RSHA headquarters, where they were interrogated and held overnight. On 5 August they were transferred to the Huis van Bewaring (House of Detention), an overcrowded prison on the Weteringschans. Two days later they were transported to the Westerbork transit camp, through which by that time more than 100,000 Jews, mostly Dutch and German, had passed. Having been arrested in hiding, they were considered criminals and sent to the Punishment Barracks for hard labour.[38]
The systematic extermination of Jews, however, took place largely outside the concentration camps. The death camps, in which more than one and a half million Jews were gassed—at Belzec, Sobibór, and Treblinka—were never officially part of the K.L. system. They had almost no inmates, since the Jews sent there seldom lived longer than a few hours. By contrast, Auschwitz, whose name has become practically a synonym for the Holocaust, was an official K.L., set up in June, 1940, to house Polish prisoners. The first people to be gassed there, in September, 1941, were invalids and Soviet prisoners of war. It became the central site for the deportation and murder of European Jews in 1943, after other camps closed. The vast majority of Jews brought to Auschwitz never experienced the camp as prisoners; more than eight hundred thousand of them were gassed upon arrival, in the vast extension of the original camp known as Birkenau. Only those picked as capable of slave labor lived long enough to see Auschwitz from the inside.

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.
