Between May 15 and July 9, 1944, some 438,000 Hungarian Jews were shipped on 147 trains to Birkenau, stretching the camp’s resources for killing beyond all limits. Because the crematoria were overcrowded, bodies were burned in pyres fueled partly by the victims’ own fat. Just prior to the deportation of Hungarian Jewry, two prisoners escaped with plans of the camp. They met with resistance leaders in Slovakia and compiled a detailed report including maps. As this report made its way to Western intelligence services in the summer of 1944, there were requests to bomb Auschwitz. Although the industrial complex adjacent to Auschwitz was bombed, the death camp and its crematoria were left untouched, a subject of controversy more than 50 years later. (See Why Wasn’t Auschwitz Bombed?)
It is badly lighted, full of draughts, with the brick floor covered by a layer of mud. The water is not drinkable; it has a revolting smell and often fails for many hours. The walls are covered by curious didactic frescoes: for example, there is the good Häftling [prisoner], portrayed stripped to the waist, about to diligently soap his sheared and rosy cranium, and the bad Häftling, with a strong Semitic nose and a greenish colour, bundled up in his ostentatiously stained clothes with a beret on his head, who cautiously dips a finger into the water of the washbasin. Under the first is written: "So bist du rein" (like this you are clean), and under the second, "So gehst du ein" (like this you come to a bad end); and lower down, in doubtful French but in Gothic script: "La propreté, c'est la santé" [cleanliness is health].[108]
On the night of the 27 February 1933 and 28 February 1933, someone set the Reichstag building on fire. This was the building where the German Parliament held their meetings. The Nazis blamed the communists. Opponents of the Nazis said that the Nazis themselves had done it to come to power. On the very same day, an emergency law called Reichstagsbrandverordnung was passed. The government claimed it was to protect the state from people trying to hurt the country. With this law, most of the civil rights of the Weimar Republic did not count any longer. The Nazis used this against the other political parties. Members of the communist and social-democratic parties were put into prison or killed.
In early February, the Polish Red Cross hospital opened in blocks 14, 21, and 22 at Auschwitz I, headed by Dr. Józef Bellert and staffed by 30 volunteer doctors and nurses from Kraków, along with around 90 former inmates. The critically injured patients—estimated at several thousands—were relocated from Birkenau and Monowitz to the main camp. Some orphaned children were adopted by Oświęcim residents, while others were transferred to Kraków, where several were adopted by Polish families, or placed in an orphanage at Harbutowice.[254] The hospital cared for more than 4,500 patients (most of them Jews) from 20 countries, suffering from starvation, alimentary dystrophy, gangrene, necrosis, internal haemorrhaging, and typhoid fever. At least 500 died. Assistance was provided by volunteers from Oświęcim and Brzeszcze, who donated money and food, cleaned hospital rooms, delivered water, washed patients, cooked meals, buried the dead, and transported the sick in horse-drawn carts between locations. Securing enough food for thousands of former prisoners was a constant challenge. The hospital director personally went from village to village to collect milk.[254]
The Allies received information about the murders from the Polish government-in-exile and Polish leadership in Warsaw, based mostly on intelligence from the Polish underground.[338][339] German citizens had access to information about what was happening, as soldiers returning from the occupied territories reported on what they had seen and done.[340] Historian Richard J. Evans states that most German citizens disapproved of the genocide.[341][h]
^ In The Drowned and the Saved (1986), Levi wrote that the concentration camps represented the epitome of the totalitarian system: "[N]ever has there existed a state that was really "totalitarian" ... Never has some form of reaction, a corrective of the total tyranny, been lacking, not even in the Third Reich or Stalin's Soviet Union: in both cases, public opinion, the magistrature, the foreign press, the churches, the feeling for justice and humanity that ten or twenty years of tyranny were not enough to eradicate, have to a greater or lesser extent acted as a brake. Only in the Lager [camp] was the restraint from below nonexistent, and the power of these small satraps absolute."[277]

Hitler’s intellectual viewpoint was influenced during his youth not only by these currents in the German tradition but also by specific Austrian movements that professed various political sentiments, notably those of pan-Germanic expansionism and anti-Semitism. Hitler’s ferocious nationalism, his contempt of the Slavs, and his hatred of the Jews can largely be explained by his bitter experiences as an unsuccessful artist living a threadbare existence on the streets of Vienna, the capital of the multiethnic Austro-Hungarian Empire.
The Franks had to be careful not be caught by the Germans. They covered all the windows with thick curtains. During the day they had to be extra quiet. They whispered when they talked and went barefoot so they could walk softly. At night, when the people working in the business below went home, they could relax a bit, but they still had to be very careful.
On 3 September 1944,[a] the group was deported on what would be the last transport from Westerbork to the Auschwitz concentration camp and arrived after a three-day journey. On the same train was Bloeme Evers-Emden, an Amsterdam native who had befriended Margot and Anne in the Jewish Lyceum in 1941.[48] Bloeme saw Anne, Margot, and their mother regularly in Auschwitz,[49] and was interviewed for her remembrances of the Frank women in Auschwitz in the television documentary The Last Seven Months of Anne Frank (1988) by Dutch filmmaker Willy Lindwer[50] and the BBC documentary Anne Frank Remembered (1995).[51]

For two years, they lived in a secret attic apartment behind the office of the family-owned business at 263 Prinsengracht Street, which Anne referred to in her diary as the Secret Annex. Otto Frank’s friends and colleagues, Johannes Kleiman, Victor Kugler, Jan Gies and Miep Gies, had previously helped to prepare the hiding place and smuggled food and clothing to the Franks at great risk to their own lives.
In March 1941, Himmler ordered a second, larger complex to be built next to the original camp. It was called Auschwitz II - Birkenau. The camp at Birkenau was divided into subsections surrounded by electric fences with barbed wire. During 1943 and 1944 the BIIb section became the location of the „Terezín family camp“. At its summit, Birkenau had over 100 000 inmates. In March 1942, the Auschwitz III camp was set up at nearby Monowitz, also known as Buna Monowitz. German company I.G. Farben set up a synthetic rubber factory there, in which it used the prisoners' slave labour. Auschwitz also had a further 45 auxiliary camps, where prisoners were forced to engage in slave labour, mostly for German companies.
Poles were viewed by Nazis as subhuman non-Aryans, and during the German occupation of Poland 2.7 million ethnic Poles were killed.[342] Polish civilians were subject to forced labour in German industry, internment, wholesale expulsions to make way for German colonists, and mass executions. The German authorities engaged in a systematic effort to destroy Polish culture and national identity. During operation AB-Aktion, many university professors and members of the Polish intelligentsia were arrested, transported to concentration camps, or executed. During the war, Poland lost an estimated 39 to 45 percent of its physicians and dentists, 26 to 57 percent of its lawyers, 15 to 30 percent of its teachers, 30 to 40 percent of its scientists and university professors, and 18 to 28 percent of its clergy.[343]

The Nazi Terror Begins After Adolf Hitler became chancellor of Germany in January 1933, he moved quickly to turn Germany into a one-party dictatorship and to organize the police power necessary to enforce Nazi policies. He persuaded his Cabinet to declare a state of emergency and end individual freedoms, including freedom of press, speech, and assembly. Individuals lost the right to privacy, which meant that officials could read people's mail, listen in on telephone conversations, and search private homes without a warrant.

Due in large part to the harsh sanctions imposed on Germany by the Treaty of Versailles that ended World War I, the German economy struggled terribly in the 1920s. During the late 1920s and early 1930s, the virulently anti-Semitic National German Socialist Workers Party (Nazi Party) led by Adolf Hitler became Germany's leading political force, winning control of the government in 1933.
Aware that as witnesses to the killings they would eventually be killed themselves, the Sonderkommandos of Birkenau Kommando III staged an uprising on 7 October 1944, following an announcement that some of them would be selected to be "transferred to another camp"—a common Nazi ruse for the murder of prisoners.[229][230] They attacked the SS guards with stones, axes, and makeshift hand grenades, which they also used to damage Crematorium IV and set it on fire. As the SS set up machine guns to attack the prisoners in Crematorium IV, the Sonderkommandos in Crematorium II also revolted, some of them managing to escape the compound.[230][231] The rebellion was suppressed by nightfall.[232]

The conservators are walking a less-trodden path in restoration. “We have more experience preserving a cathedral than the remains of an extermination camp,” said Piotr Cywinski, who turns 43 on Thursday and is the director of the Auschwitz-Birkenau State Museum, which runs the site. Auschwitz, he said, “is the last place where you can still effectively take the measure of the spatial organization of the progression of the Shoah.”

In March 1933, the Enabling Act, an amendment to the Weimar Constitution, passed in the Reichstag by a vote of 444 to 94.[17] This amendment allowed Hitler and his cabinet to pass laws—even laws that violated the constitution—without the consent of the president or the Reichstag.[18] As the bill required a two-thirds majority to pass, the Nazis used intimidation tactics as well as the provisions of the Reichstag Fire Decree to keep several Social Democratic deputies from attending, and the Communists had already been banned.[19][20] On 10 May, the government seized the assets of the Social Democrats, and they were banned on 22 June.[21] On 21 June, the SA raided the offices of the German National People's Party – their former coalition partners – and they disbanded on 29 June. The remaining major political parties followed suit. On 14 July 1933 Germany became a one-party state with the passage of a law decreeing the NSDAP to be the sole legal party in Germany. The founding of new parties was also made illegal, and all remaining political parties which had not already been dissolved were banned.[22] The Enabling Act would subsequently serve as the legal foundation for the dictatorship the NSDAP established.[23] Further elections in November 1933, 1936, and 1938 were Nazi-controlled, with only members of the NSDAP and a small number of independents elected.[24]

Otto Frank survived his internment in Auschwitz. After the war ended, he returned to Amsterdam, where he was sheltered by Jan and Miep Gies as he attempted to locate his family. He learned of the death of his wife, Edith, in Auschwitz, but remained hopeful that his daughters had survived. After several weeks, he discovered Margot and Anne had also died. He attempted to determine the fates of his daughters' friends and learned many had been murdered. Sanne Ledermann, often mentioned in Anne's diary, had been gassed along with her parents; her sister, Barbara, a close friend of Margot's, had survived.[63] Several of the Frank sisters' school friends had survived, as had the extended families of Otto and Edith Frank, as they had fled Germany during the mid-1930s, with individual family members settling in Switzerland, the United Kingdom, and the United States.[64]
Under the leadership of Adolf Hitler (1889-1945), the National Socialist German Workers’ Party, or Nazi Party, grew into a mass movement and ruled Germany through totalitarian means from 1933 to 1945. Founded in 1919 as the German Workers’ Party, the group promoted German pride and anti-Semitism, and expressed dissatisfaction with the terms of the Treaty of Versailles, the 1919 peace settlement that ended World War I (1914-1918) and required Germany to make numerous concessions and reparations. Hitler joined the party the year it was founded and became its leader in 1921. In 1933, he became chancellor of Germany and his Nazi government soon assumed dictatorial powers. After Germany’s defeat in World War II (1939-45), the Nazi Party was outlawed and many of its top officials were convicted of war crimes related to the murder of some 6 million European Jews during the Nazis’ reign.

The Nazis, the far-right monarchists, the reactionary German National People's Party (DNVP) and others, such as monarchist officers in the German Army and several prominent industrialists, formed an alliance in opposition to the Weimar Republic on 11 October 1931 in Bad Harzburg, officially known as the "National Front", but commonly referred to as the Harzburg Front.[30] The Nazis stated that the alliance was purely tactical and they continued to have differences with the DNVP. The Nazis described the DNVP as a bourgeois party and they called themselves an anti-bourgeois party.[30] After the elections of July 1932, the alliance broke down when the DNVP lost many of its seats in the Reichstag. The Nazis denounced them as "an insignificant heap of reactionaries".[31] The DNVP responded by denouncing the Nazis for their socialism, their street violence and the "economic experiments" that would take place if the Nazis ever rose to power.[32] But amidst an inconclusive political situation in which conservative politicians Franz von Papen and Kurt von Schleicher were unable to form stable governments without the Nazis, Papen proposed to President Hindenburg to appoint Hitler as Chancellor at the head of a government formed primarily of conservatives, with only three Nazi ministers.[33][34] Hindenburg did so, and contrary to the expectations of Papen and the DNVP, Hitler was soon able to establish a Nazi one-party dictatorship.[35]
Frequent and often contradictory directives were issued by Interior Minister Wilhelm Frick, Bernhard Rust of the Reich Ministry of Science, Education and Culture, and other agencies regarding content of lessons and acceptable textbooks for use in primary and secondary schools.[354] Books deemed unacceptable to the regime were removed from school libraries.[355] Indoctrination in National Socialist thought was made compulsory in January 1934.[355] Students selected as future members of the party elite were indoctrinated from the age of 12 at Adolf Hitler Schools for primary education and National Political Institutes of Education for secondary education. Detailed National Socialist indoctrination of future holders of elite military rank was undertaken at Order Castles.[356]
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.
In spite of efforts to prepare the country militarily, the economy could not sustain a lengthy war of attrition. A strategy was developed based on the tactic of Blitzkrieg ("lightning war"), which involved using quick coordinated assaults that avoided enemy strong points. Attacks began with artillery bombardment, followed by bombing and strafing runs. Next the tanks would attack and finally the infantry would move in to secure the captured area.[225] Victories continued through mid-1940, but the failure to defeat Britain was the first major turning point in the war. The decision to attack the Soviet Union and the decisive defeat at Stalingrad led to the retreat of the German armies and the eventual loss of the war.[226] The total number of soldiers who served in the Wehrmacht from 1935 to 1945 was around 18.2 million, of whom 5.3 million died.[150]
In January 1923, France occupied the Ruhr industrial region as a result of Germany's failure to meet its reparations payments. This led to economic chaos, the resignation of Wilhelm Cuno's government and an attempt by the German Communist Party (KPD) to stage a revolution. The reaction to these events was an upsurge of nationalist sentiment. Nazi Party membership grew sharply to about 20,000.[65] By November, Hitler had decided that the time was right for an attempt to seize power in Munich, in the hope that the Reichswehr (the post-war German military) would mutiny against the Berlin government and join his revolt. In this, he was influenced by former General Erich Ludendorff, who had become a supporter—though not a member—of the Nazis.
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.
From March 1944, Bergen-Belsen gradually became a concentration camp. The Germans initially began transferring, from other camps, prisoners they classified as ‘unfit to work’. As more transports arrived from Flossenbürg, Gross-Rosen, Ravensbrück, Neuengamme, Mauthausen, and Buchenwald concentration camps, the prisoners were housed in the former ‘prisoners’ camp’. German convicts, transferred from Dora, served as ‘block elders’ and Kapos. They treated other inmates brutally.

Gradowski was one of the Jewish prisoners in Auschwitz’s Sonderkommando: those forced to escort new arrivals into the gas chambers, haul the newly dead bodies to the crematoriums, extract any gold teeth and then burn the corpses. Gradowski, a young married man whose entire family was murdered, reportedly maintained his religious faith, reciting the kaddish (mourner’s prayer) each evening for the victims of each transport—including Peter van Pels’ father, who was gassed a few weeks after his arrival in Auschwitz on September 6, 1944. Gradowski recorded his experiences in Yiddish in documents he buried, which were discovered after the war; he himself was killed on October 7, 1944, in a Sonderkommando revolt that lasted only one day. (The documents written by Gradowski and several other prisoners inspired the 2015 Hungarian film Son of Saul, which, unsurprisingly, was no blockbuster, despite an Academy Award and critical acclaim.)

The Nazi Terror Begins After Adolf Hitler became chancellor of Germany in January 1933, he moved quickly to turn Germany into a one-party dictatorship and to organize the police power necessary to enforce Nazi policies. He persuaded his Cabinet to declare a state of emergency and end individual freedoms, including freedom of press, speech, and assembly. Individuals lost the right to privacy, which meant that officials could read people's mail, listen in on telephone conversations, and search private homes without a warrant.
Between 1940 and 1942, the French interned Jewish refugee families fleeing Nazi oppression elsewhere in Europe in Rivesaltes for the same reason. Lists of those incarcerated include a transport of Czech Jewish children: Brothers Salomon and Abraham Davidovic were 13 and 14 when they arrived. Conditions deteriorated. Directors complained in 1941 of no heat. Illness spread. Babies and the elderly died. The situation worsened when the Nazi-puppet Vichy regime assumed control of the camp in 1942 and began deporting its 7,000 foreign Jewish refugee prisoners to the gas chambers of Auschwitz. There, mothers and children were not separated but instead went to their deaths together.
Last, and perhaps most ominously for our comparisons with the Holocaust, the camps can be the first step toward darker developments, as some have already argued. These “concentration camps” will not lead to gas chambers, but their existence may well lead to the erosion of respect for human rights, the rule of law and government accountability that characterized the Third Reich. Unless, of course, the children are all actors.
Höss was succeeded as Auschwitz commandant in November 1943 by SS Obersturmbannführer Arthur Liebehenschel, who served until 15 May 1944. SS Sturmbannführer Richard Baer became commandant of Auschwitz I on 11 May 1944, and SS Obersturmbannführer Fritz Hartjenstein of Auschwitz II from 22 November 1943, followed by SS Obersturmbannführer Josef Kramer from 15 May 1944 until the camp's liquidation in January 1945. Heinrich Schwarz was commandant of Auschwitz III from the point at which it became an autonomous camp in November 1943 until its liquidation.[83]
The Zyklon B was delivered by ambulance to the crematoria by a special SS bureau known as the Hygienic Institute.[104] The actual delivery of the gas to the victims was always handled by the SS, on the order of the supervising SS doctor.[174][175] After the doors were shut, SS men dumped in the Zyklon B pellets through vents in the roof or holes in the side of the chamber. The victims were dead within 20 minutes.[174] Despite the thick concrete walls, screaming and moaning from within could be heard outside. In one failed attempt to muffle the noise, two motorcycle engines were revved up to full throttle nearby, but the sound of yelling could still be heard over the engines.[176]
Pankoke started working for the FBI in the 1980s, spending his first four years as an agent in a small field office in Wisconsin. In 1992, he was transferred to Miami, where he helped build cases against Colombian cartels. After the Sept. 11, 2001, attacks, he was involved in FBI undercover operations, including cases that took him out of the country, he said.
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]
Following the June 1941 German invasion of the Soviet Union, the Nazis increased the number of prisoner-of-war (POW) camps. Some new camps were built at existing concentration camp complexes (such as Auschwitz) in occupied Poland. The camp at Lublin, later known as Majdanek, was established in the autumn of 1941 as a POW camp and became a concentration camp in 1943. Thousands of Soviet POWs were shot or gassed there.
Hitler's conception of the Aryan Herrenvolk ("Aryan master race") excluded the vast majority of Slavs from central and eastern Europe (i.e. Poles, Russians, Ukrainians, etc.). They were regarded as a race of men not inclined to a higher form of civilization, which was under an instinctive force that reverted them back to nature. The Nazis also regarded the Slavs as having dangerous Jewish and Asiatic, meaning Mongol, influences.[158] Because of this, the Nazis declared Slavs to be Untermenschen ("subhumans").[159] Nazi anthropologists attempted to scientifically prove the historical admixture of the Slavs who lived further East and leading Nazi racial theorist Hans Günther regarded the Slavs as being primarily Nordic centuries ago but he believed that they had mixed with non-Nordic types over time.[160] Exceptions were made for a small percentage of Slavs who the Nazis saw as descended from German settlers and therefore fit to be Germanised and considered part of the Aryan master race.[161] Hitler described Slavs as "a mass of born slaves who feel the need for a master".[162] The Nazi notion of Slavs as inferior served as a legitimization of their desire to create Lebensraum for Germans and other Germanic people in eastern Europe, where millions of Germans and other Germanic settlers would be moved into once those territories were conquered, while the original Slavic inhabitants were to be annihilated, removed or enslaved.[163] Nazi Germany's policy changed towards Slavs in response to military manpower shortages, forced it to allow Slavs to serve in its armed forces within the occupied territories in spite of the fact that they were considered "subhuman".[164]
In Auschwitz and Majdanek, which had the role of both being a working and an extermination camp, Jews were divided upon arrival into those capable of working ands those not. The last group was sent directly to the gas chambers, whereas those able to work had to work themselves to death in SS’s industries – or they were executed when they worn down. In Auschwitz, the Jews worked in the so-called Monowitz working camp (Auschwitz III) in factories, or they were hired out to private businesses such as the chemical corporation I.G. Farben or the SS’s own factories.
Memory is not something that is acquired once and stays on forever. The moment that the last eyewitnesses and survivors pass away, we have to work together to build on that which remains: the testimonies of those former prisoners and the authentic artifacts connected with Auschwitz. Each item can have its own enormous meaning and should find its place in the collection of the Auschwitz Memorial. Here, it will be preserved, studied, and displayed. Its place is here. 
Fleeing Germans also torched a couple of dozen of the wooden barracks at Birkenau. Many of the camp buildings that were left largely intact were later taken apart by Poles desperate for shelter. Birkenau remains the starkest, most tangible, most haunting reminder of what Dwork says was the “greatest catastrophe Western civilization permitted, and endured.”
Until 1990, the museum’s directors were all former prisoners. Cywinski is just 37. His office is on the first floor of a former SS administration building directly across from a former gas chamber and crematorium. He tells me that Auschwitz is about to slip into history. The last survivors will soon die, and with them the living links to what happened here. Preserving the site becomes increasingly important, Cywinski believes: younger generations raised on TV and movie special effects need to see and touch the real thing.
After the arrival of a transport at the ramp in Birkenau, the process known as selection took place. SS officers decided who would be taken to work, and who would be sent directly to the gas chambers. Often it was mere chance or the mood of the SS officer that decided whether someone died immediately or had a hope of survival. The prisoners selected for slave labour were sent to one of the many auxiliary camps at Auschwitz or elsewhere in the Nazi concentration camp system. Their aim was „Vernichtung durch Arbeit“ - extermination through labour.
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.
In 1944 we were sent on a death march from Birkenau to Oranienburg and from there to Buchenwald. Then to a quarry, where we were ordered to drill into the mountains to make some sort of secret city. From there we walked back to Buchenwald. Whoever was incapable of walking was shot. From there, big trains took us to Theresienstadt just as the Soviets were bombing the rails. We could sense that the Germans were almost destroyed. For 17 days we had no water, no food, nothing. Despite the hardship I was doing OK compared to others. I still had the capability to clamber on to the cattle trains without help.
The extermination camp Treblinka was working from July 1942 to November 1943. In August 1943 an uprising destroyed many of the facilities. 900,000 Jews lost their lives in this camp.    Auschwitz-Birkenau, which also functioned as a concentration camp and a work camp, became the largest killing centre. It is estimated that between 1 and 2 million were killed in the extermination camp Auschwitz-Birkenau. The first gassing experiments, involving 250 Polish and 600 Soviet POW’s, were carried out as early as September 1941. The extermination camp was started up in March 1942 and ended its work in November 1944.
I married a Polish Jew and we settled in Germany, the “Täterland” – the land of the perpetrator – after being forced out of Czechoslovakia after the collapse of the Prague Spring in 1968. It does sometimes feel like a strange decision to live in Germany because the Holocaust is just so omnipresent here and there is a growing antisemitism that scares me, especially when you feel it in Germany, of all places, which is why I always repeat what Primo Levi wrote: “What happened can happen again.”
Jews, especially German, Western European and Russian, also worked as slave labour in work camps in Germany. The Kraft durch Freude Volkswagen works in Wolfsburg, for example, used the “cheap” Jewish slave labourers. A tile work in Sachsenhausen, owned and operated by the SS, used Jews and other slave labourers. In the Harz, near the concentration camp Dora-Mittelbau, Jews worked in an underground weapons factory.
Uniquely at Auschwitz, prisoners were tattooed with a serial number, on their left breast for Soviet prisoners of war[97] and on the left arm for civilians.[98] Categories of prisoner were distinguishable by triangular pieces of cloth (German: Winkel) sewn onto on their jackets below their prisoner number. Political prisoners (Schutzhäftlinge or Sch), mostly Poles, had a red triangle, while criminals (Berufsverbrecher or BV) were mostly German and wore green. Asocial prisoners (Asoziale or Aso), which included vagrants, prostitutes and the Roma, wore black. Purple was for Jehovah's Witnesses (Internationale Bibelforscher-Vereinigung or IBV)'s and pink for gay men, who were mostly German.[99] An estimated 5,000–15,000 gay men prosecuted under German Penal Code Section 175 (proscribing sexual acts between men) were detained in concentration camps, of which an unknown number were sent to Auschwitz.[100] Jews wore a yellow badge, the shape of the Star of David, overlaid by a second triangle if they also belonged to a second category. The nationality of the inmate was indicated by a letter stitched onto the cloth. A racial hierarchy existed, with German prisoners at the top. Next were non-Jewish prisoners from other countries. Jewish prisoners were at the bottom.[101]

The lead editors of the Encyclopedia of Camps and Ghettos, 1933–1945 of the United States Holocaust Memorial Museum, Geoffrey Megargee and Martin Dean, cataloged some 42,500 Nazi ghettos and camps throughout Europe, spanning German-controlled areas from France to Russia and Germany itself, operating from 1933 to 1945. They estimate that 15 million to 20 million people died or were imprisoned in the sites.[36]
