At the same time, public interest in the camp has never been higher. Visits have doubled this decade, from 492,500 in 2001 to more than 1 million in 2009. Since Poland joined the European Union in 2004, Krakow has become a popular destination for foreign tourists, and Auschwitz is a must stop on many itineraries. A visit is also part of education programs in Israel, Britain and other countries. On peak days, as many as 30,000 visitors file through the camp’s buildings.
Since the Nazis extended the Rassenschande ("race defilement") law to all foreigners at the beginning of the war,[139] pamphlets were issued to German women which ordered them to avoid sexual relations with foreign workers who were brought to Germany and the pamphlets also ordered German women to view these same foreign workers as a danger to their blood.[190] Although the law was applicable to both genders, German women were punished more severely for having sexual relations with foreign forced labourers in Germany.[191] The Nazis issued the Polish decrees on 8 March 1940 which contained regulations concerning the Polish forced labourers (Zivilarbeiter) who were brought to Germany during World War II. One of the regulations stated that any Pole "who has sexual relations with a German man or woman, or approaches them in any other improper manner, will be punished by death".[192]
Early one morning I met Stos, a retired architect, at his small first-floor apartment on the outskirts of Krakow. We sat in his small, dark dining room, a plate of jam-filled ginger cookies on the starched white tablecloth between us. He said he grew up in Tarnow, Poland, about 50 miles from Krakow. He remembers the day the Nazis shipped him off to Auschwitz: June 13, 1940. It had been almost a year since Germany invaded Poland and launched its campaign to destroy the nation. Following instructions issued by SS chief Reinhard Heydrich—“the leading strata of the population should be rendered harmless”—the SS killed some 20,000 Poles, mainly priests, politicians and academics, in September and October 1939. Stos was an 18-year-old Boy Scout and a member of a Catholic youth organization. Germans put him and 727 other Poles, mostly university and trade-school students, in first-class train cars and told them they were going to work on German farms.
Nazism rejected the Marxist concept of class conflict, and it praised both German capitalists and German workers as essential to the Volksgemeinschaft. In the Volksgemeinschaft, social classes would continue to exist, but there would be no class conflict between them.[170] Hitler said that "the capitalists have worked their way to the top through their capacity, and as the basis of this selection, which again only proves their higher race, they have a right to lead."[171] German business leaders co-operated with the Nazis during their rise to power and received substantial benefits from the Nazi state after it was established, including high profits and state-sanctioned monopolies and cartels.[172] Large celebrations and symbolism were used extensively to encourage those engaged in physical labour on behalf of Germany, with leading National Socialists often praising the "honour of labour", which fostered a sense of community (Gemeinschaft) for the German people and promoted solidarity towards the Nazi cause.[173] To win workers away from Marxism, Nazi propaganda sometimes presented its expansionist foreign policy goals as a "class struggle between nations."[171] Bonfires were made of school children's differently coloured caps as symbolic of the unity of different social classes.[174]
One evening at inspection, the camp commander gave us an address in which he said that we were responsible for the murder of Herr vom Rath and that therefore we had committed a crime against the nation and the state; that we were in a camp for protective custody, which was not a prison or a penitentiary at all, nor a sanitarium either, but solely an educational institution; that we should learn here how to behave in dealing with a 'guest nation' (he really said 'guest' nation instead of 'host' nation); that the main thing was unconditional obedience and that all S.S. men were our superior officers; that each attempt at disobedience would be punished, in some cases by corporal punishment, and that all S. S. men were entitled to use their arms in any attempt at resistance or escape.

Then, on January 27, 1945, the Red Army reached the camp. Inside, they found prisoners covered in excrement and starving to death, children who had been used for medical experiments, and other shocking evidence of the Nazis’ crimes. At Birkenau, the guards had failed to destroy some of the storerooms where prisoners’ stolen belongings were stored before being transported back to the Reich. Among the remainingitems were 7.7 tons of human hair, 370,000 men’s suits and 837,000 women’s coats and dresses.

Auschwitz I, ul. Stanisławy Leszczyńskiej 11. The first camp to be used (called Stammlager by the Germans), consisting of old Polish Army barracks later converted into inmate housing, torture chambers, execution grounds, and SS administrative buildings. The infamous Arbeit macht frei gate is found here. Inside most of the barrack buildings are historical exhibits regarding the various nationalities held in the camp, video displays, photos, and personal belongings illustrating the life and cruelties of the Nazi terror. The only remaining gas chamber is found in Auschwitz I but note that, as indicated within the chamber, it was reconstructed to its wartime layout after the war.  edit
Although there have been persistent claims of betrayal by an informant, the source of the information that led the authorities to raid the Achterhuis has never been identified. Night watchman Martin Sleegers and an unidentified police officer investigated a burglary at the premises in April 1944 and came across the bookcase concealing the secret door. Tonny Ahlers, a member of the National Socialist Movement in the Netherlands (NSB), was suspected of being the informant by Carol Ann Lee, biographer of Otto Frank. Another suspect is stockroom manager Willem van Maaren. The Annex occupants did not trust him, as he seemed inquisitive regarding people entering the stockroom after hours. He once unexpectedly asked the employees whether there had previously been a Mr. Frank at the office. Lena Hartog was suspected of being the informant by Anne Frank's biographer Melissa Müller. Several of these suspects knew one another and might have worked in collaboration. While virtually everyone connected with the betrayal was interrogated after the war, no one was definitively identified as being the informant.[41]
In 1933, when Adolf Hitler assumed power in the German government, the usage of "Nazi" diminished in Germany, although Austrian anti-Nazis continued to use the term,[18] and the use of "Nazi Germany" and "Nazi regime" was popularised by anti-Nazis and German exiles abroad. Thereafter, the term spread into other languages and eventually was brought back to Germany after World War II.[22] In English, the term is not considered slang, and has such derivatives as Nazism and denazification.
In addition to eliminating Jews, the Nazis planned to reduce the population of the conquered territories by 30 million people through starvation in an action called the Hunger Plan. Food supplies would be diverted to the German army and German civilians. Cities would be razed and the land allowed to return to forest or resettled by German colonists.[327] Together, the Hunger Plan and Generalplan Ost would have led to the starvation of 80 million people in the Soviet Union.[328] These partially fulfilled plans resulted in the democidal deaths of an estimated 19.3 million civilians and prisoners of war (POWs).[329] During the course of the war, the Soviet Union lost a total of 27 million people; less than nine million of these were combat deaths.[330] One in four of the Soviet population were killed or wounded.[331]
After this we were taken to another room in which we were forced to strip. Then our heads were clipped short and all signs of beard were removed. According to an old tradition in Germany, the cropped hair is a distinguishing mark of the serf in contrast to the free man. After this procedure and a sort of 'medical examination' by another inmate employed as attendant, we received the benefit of a hot shower, which somewhat refreshed us and loosened up our limbs, stiff from the long stand in the cold.
Already as commandant of Dachau in 1933, Eicke developed an organization and procedures to administer and guard a concentration camp. He issued regulations for the duties of the perimeter guards and for treatment of the prisoners. The organization, structure, and practice developed at Dachau in 1933–34 became the model for the Nazi concentration camp system as it expanded. Among Eicke's early trainees at Dachau was Rudolf Höss, who later commanded the Auschwitz concentration camp.
By 1940, the CCI came under the control of the Verwaltung und Wirtschaftshauptamt Hauptamt (VuWHA; Administration and Business office) which was set up under Oswald Pohl.[25] Then in 1942, the CCI became Amt D (Office D) of the consolidated main office known as the SS-Wirtschafts-Verwaltungshauptamt (SS Economic and Administrative Department; WVHA) under Pohl.[25] In 1942, the SS built a network of extermination camps to systematically kill millions of prisoners by gassing. The extermination camps (Vernichtungslager) and death camps (Todeslager) were camps whose primary function was genocide. The Nazis themselves distinguished the concentration camps from the extermination camps.[26][27] The British intelligence service had information about the concentration camps, and in 1942 Jan Karski delivered a thorough eyewitness account to the government.
