As a result of their defeat in World War I and the resulting Treaty of Versailles, Germany lost Alsace-Lorraine, Northern Schleswig, and Memel. The Saarland temporarily became a protectorate of France under the condition that its residents would later decide by referendum which country to join, and Poland became a separate nation and was given access to the sea by the creation of the Polish Corridor, which separated Prussia from the rest of Germany, while Danzig was made a free city.[163]

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.

Construction of crematorium I began at Auschwitz I at the end of June or beginning of July 1940.[26] Initially intended not for mass murder but for prisoners who had been executed or had otherwise died in the camps, the crematorium was in operation from August 1940 until July 1943, by which time the crematoria at Auschwitz II had taken over.[27] By May 1942 three ovens had been installed in crematorium I, which together could burn 340 bodies in 24 hours.[28]
Beginning in April 1933, scores of measures defining the status of Jews and their rights were instituted.[49] These measures culminated in the establishment of the Nuremberg Laws of 1935, which stripped them of their basic rights.[50] The Nazis would take from the Jews their wealth, their right to intermarry with non-Jews, and their right to occupy many fields of labour (such as law, medicine, or education). Eventually the Nazis declared the Jews as undesirable to remain among German citizens and society.[51]
Various other German industrial enterprises, such as Krupp and Siemens-Schuckert, built factories with their own subcamps.[68] There were around 40[69] or 50[70] such camps, 28 of them near industrial plants, each camp holding hundreds or thousands of prisoners.[71] Designated as Aussenlager (external camp), Nebenlager (extension or subcamp), or Arbeitslager (labor camp),[69] camps were built at Blechhammer, Jawiszowice, Jaworzno, Lagisze, Mysłowice, Trzebinia, and centers as far afield as the Protectorate of Bohemia and Moravia in Czechoslovakia.[72][73][74] Industries with satellite camps included coal mines, foundries and other metal works, and chemical plants. Prisoners were also made to work in forestry and farming.[75] Budy, for example, was a farming subcamp where prisoners worked 12-hour days, often in the fields, but sometimes tending animals, cleaning ponds, digging ditches, and making compost. Human ashes from the crematorium were mixed with sod and manure to make the compost.[76] Incidents of sabotage to decrease production took place in several subcamps, including Charlottengrube, Gleiwitz II, and Rajsko.[77]

There have been protracted disputes over the perceived Christianization of the site. Pope John Paul II celebrated mass over the train tracks leading to Auschwitz II-Birkenau on 7 June 1979,[291] and called the camp "the Golgotha of our age", referring to the crucifixion of Jesus.[292] More controversy followed when Carmelite nuns founded a convent in 1984 in a former theater outside the camp's perimeter, near block 11 of Auschwitz I,[293] after which a local priest and some survivors erected a large cross—one that had been used during the pope's mass—behind block 11 to commemorate 152 Polish inmates shot by the Germans in 1941.[294][295] After a long dispute, Pope John Paul II intervened, and the nuns moved the convent elsewhere in 1993.[296] The cross remained, triggering the "War of the Crosses", as more crosses were erected to commemorate Christian victims, despite international objections. The Polish government and Catholic Church eventually agreed to remove all but the original.[297]
The preservation lab, with high-end technology, opened in 2003. One afternoon last week, Nel Jastrzebiowska, 37, a paper conservator, was using a rubber eraser to clean a row of papers in files. They were letters on Auschwitz stationery, written in German in rosy prose intended to slip past the censors. “I’m in good health,” one read, adding, “Send me money.”
When Hitler became chancellor of Germany on January 1, 1933, conditions for Jews like the Franks and other so-called undesirables in Germany immediately deteriorated. By summer, freedom of speech and assembly were suspended for everyone in Germany, the Gestapo was formed, Jewish businesses—including medical and legal practices—were boycotted, and a law excluding non-Aryans from government removed Jews from government and teaching positions.
Otto and Edith Frank planned to go into hiding with the children on 16 July 1942, but when Margot received a call-up notice from the Zentralstelle für jüdische Auswanderung (Central Office for Jewish Emigration) on 5 July, ordering her to report for relocation to a work camp, they were forced to move the plan ten days forward.[20] Shortly before going into hiding, Anne gave her friend and neighbour Toosje Kupers a book, a tea set, a tin of marbles, and the family cat for safekeeping. As the Associated Press reports: "'I'm worried about my marbles, because I'm scared they might fall into the wrong hands,' Kupers said Anne told her. 'Could you keep them for me for a little while?'"[21]
Today, at the beginning of the twenty-first century, the diary has not lost its power: in 2002, Habimah staged the play for the sixth time in Israel, an average of once per decade. In March 2002, Carol Ann Lee’s biography of Otto Frank, The Hidden Life of Otto Frank, had the Netherlands in an uproar. She places responsibility for the discovery of the attic’s inhabitants on Anton (Tony) Ahlers, a sworn antisemite and a member of the Dutch Nazi party who systematically informed on Jews. Ahlers was Frank’s business partner and knew that his spice company had done business with the Wehrmacht at the beginning of the war. Frank evidently paid Ahlers hush money even before his family entered the attic. Afterwards, he paid him not to reveal to the Dutch government that he had done business with the Wehrmacht, and apparently continued to pay him off until his death in 1980. Following the public furor, which spread to the United States, The Netherlands State Institute for War Documentation, the main organization that researches Anne Frank’s legacy today, announced that it would investigate Lee’s claims and soon publish its findings. Lee’s biography turns Anne’s father, the man who influenced her more than anyone and won her total admiration, into a man of flesh and blood devoid of the saintly image that had previously clung to him. It also placed the issues of informing and collaboration in the Netherlands and in Europe back on the public agenda, along with the question of the relationship to the Jewish citizens of those countries and their fate. Once more, Anne’s image hovers over the controversy, with its dark eyes and penetrating gaze, its hopes for a new world and faith in humankind.

Up to this point, Auschwitz accounted for only 11 percent of the victims of the 'Final Solution'. However, in August 1942, planning began for the construction of four large-scale gassing facilities. It appears from the plans that the first two gas chambers were adapted from mortuaries which, with the huge crematoria attached to them, were initially intended to cope with mortalities amongst the slave labor force in the camp, now approaching 100,000 and subject to a horrifying death rate. But from the autumn of 1942, it seems clear that the SS planners and civilian contractors were intending to build a mass-murder plant.

The Nazis were initially very hostile to Catholics because most Catholics supported the German Centre Party. Catholics opposed the Nazis' promotion of compulsory sterilization of those whom they deemed inferior and the Catholic Church forbade its members to vote for the Nazis. In 1933, extensive Nazi violence occurred against Catholics due to their association with the Centre Party and their opposition to the Nazi regime's sterilization laws.[212] The Nazis demanded that Catholics declare their loyalty to the German state.[213] In their propaganda, the Nazis used elements of Germany's Catholic history, in particular the German Catholic Teutonic Knights and their campaigns in Eastern Europe. The Nazis identified them as "sentinels" in the East against "Slavic chaos", though beyond that symbolism, the influence of the Teutonic Knights on Nazism was limited.[214] Hitler also admitted that the Nazis' night rallies were inspired by the Catholic rituals which he had witnessed during his Catholic upbringing.[215] The Nazis did seek official reconciliation with the Catholic Church and they endorsed the creation of the pro-Nazi Catholic Kreuz und Adler, an organization which advocated a form of national Catholicism that would reconcile the Catholic Church's beliefs with Nazism.[213] On 20 July 1933, a concordat (Reichskonkordat) was signed between Nazi Germany and the Catholic Church, which in exchange for acceptance of the Catholic Church in Germany required German Catholics to be loyal to the German state. The Catholic Church then ended its ban on members supporting the Nazi Party.[213]
These guards were the core of what became, a few years later, the much feared Death’s-Head S.S. The name, along with the skull-and-crossbones insignia, was meant to reinforce the idea that the men who bore it were not mere prison guards but front-line soldiers in the Nazi war against enemies of the people. Himmler declared, “No other service is more devastating and strenuous for the troops than just that of guarding villains and criminals.” The ideology of combat had been part of the DNA of Nazism from its origin, as a movement of First World War veterans, through the years of street battles against Communists, which established the Party’s reputation for violence. Now, in the years before actual war came, the K.L. was imagined as the site of virtual combat—against Communists, criminals, dissidents, homosexuals, Jehovah’s Witnesses, and Jews, all forces working to undermine the German nation.
A useful analogy requires that we move beyond a Google image search and truly interrogate history. If we do, we may arrive at the Camp de Rivesaltes, an ad hoc facility created from an empty military camp in southern France. Its first prisoners in 1938 were not Jews but Spanish refugees who had fought against Francisco Franco’s victorious fascists. They were fleeing inevitable persecution from the Spanish dictator. The goal of that temporary concentration camp was to prevent the further dispersion of the Spanish refugees and their settlement in France while a repatriation solution was found. It never was.
A parallel system operated later at Birkenau in 1942-43, except that for the majority the 'showers' proved to be gas chambers. Only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the 'central sauna' before being assigned barracks. In May 1944, a spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944.
While civilian efforts had an impact on public opinion, the army was the only organisation with the capacity to overthrow the government.[443][444] A major plot by men in the upper echelons of the military originated in 1938. They believed Britain would go to war over Hitler's planned invasion of Czechoslovakia, and Germany would lose. The plan was to overthrow Hitler or possibly assassinate him. Participants included Generaloberst Ludwig Beck, Generaloberst Walther von Brauchitsch, Generaloberst Franz Halder, Admiral Wilhelm Canaris, and Generalleutnant Erwin von Witzleben, who joined a conspiracy headed by Oberstleutnant Hans Oster and Major Helmuth Groscurth of the Abwehr. The planned coup was cancelled after the signing of the Munich Agreement in September 1938.[445] Many of the same people were involved in a coup planned for 1940, but again the participants changed their minds and backed down, partly because of the popularity of the regime after the early victories in the war.[446][447] Attempts to assassinate Hitler resumed in earnest in 1943, with Henning von Tresckow joining Oster's group and attempting to blow up Hitler's plane in 1943. Several more attempts followed before the failed 20 July 1944 plot, which was at least partly motivated by the increasing prospect of a German defeat in the war.[448][449] The plot, part of Operation Valkyrie, involved Claus von Stauffenberg planting a bomb in the conference room at Wolf's Lair at Rastenburg. Hitler, who narrowly survived, later ordered savage reprisals resulting in the execution of more than 4,900 people.[450]

Within this framework, "racially inferior" peoples, such as Jews and Gypsies, would be eliminated from the region. Nazi foreign policy aimed from the beginning to wage a war of annihilation against the Soviet Union, and the peacetime years of the Nazi regime were spent preparing the German people for war. In the context of this ideological war, the Nazis planned and implemented the Holocaust, the mass murder of the Jews, who were considered the primary "racial" enemy.
[Hitler] compiled a most extensive set of revolutionary goals (calling for radical social and political change); he mobilized a revolutionary following so extensive and powerful that many of his aims were achieved; he established and ran a dictatorial revolutionary state; and he disseminated his ideas abroad through a revolutionary foreign policy and war. In short, he defined and controlled the National Socialist revolution in all its phases.[283]
Anne Frank is included as one of the topics in the Canon of Dutch History, which was prepared by a committee headed by Frits van Oostrom and presented to the Minister of Education, Culture and Science, Maria van der Hoeven, in 2006; the Canon is a list of fifty topics that aims to provide a chronological summary of Dutch history to be taught in primary schools and the first two years of secondary school in the Netherlands. A revised version, which still includes her as one of the topics, was presented to the Dutch government on 3 October 2007.

When I returned this past autumn, the hair was a barely differentiated mass of gray, more like wool than human locks. Only the occasional braid signaled the remnants of something unprecedented and awful—the site where the Third Reich perpetrated the largest mass murder in human history. At least 1.1 million people were killed here, most within hours of their arrival.
On April 27, 1940, Heinrich Himmler ordered the construction of a new camp near Oswiecim, Poland (about 37 miles or 60 km west of Krakow). The Auschwitz Concentration Camp ("Auschwitz" is the German spelling of "Oswiecim") quickly became the largest Nazi concentration and death camp. By the time of its liberation, Auschwitz had grown to include three large camps and 45 sub-camps.
The Auschwitz Jewish Center (AJC) in Oświęcim, operated by the Museum of Jewish Heritage — A Living Memorial to the Holocaust, is just two miles from the Auschwitz–Birkenau death camps. The only Jewish presence in the vicinity of Auschwitz, the Center opened its doors in September 2000 so that people from around the world could gather to learn, pray, and remember the victims of the Holocaust.
Surely there is nothing left to say about Anne Frank, except that there is everything left to say about her: all the books she never lived to write. For she was unquestionably a talented writer, possessed of both the ability and the commitment that real literature requires. Quite the opposite of how an influential Dutch historian described her work in the article that spurred her diary’s publication—a “diary by a child, this de profundis stammered out in a child’s voice”—Frank’s diary was not the work of a naif, but rather of a writer already planning future publication. Frank had begun the diary casually, but later sensed its potential; upon hearing a radio broadcast in March of 1944 calling on Dutch civilians to preserve diaries and other personal wartime documents, she immediately began to revise two years of previous entries, with a title (Het Achterhuis, or The House Behind) already in mind, along with pseudonyms for the hiding place’s residents. Nor were her revisions simple corrections or substitutions. They were thoughtful edits designed to draw the reader in, intentional and sophisticated. Her first entry in the original diary, for instance, begins with a long description of her birthday gifts (the blank diary being one of them), an entirely unself-conscious record by a 13-year-old girl. The first entry in her revised version, on the other hand, begins with a deeply self-aware and ironic pose: “It’s an odd idea for someone like me to keep a diary; not only because I have never done so before, but because it seems to me that neither I—nor for that matter anyone else—will be interested in the unbosomings of a 13-year-old schoolgirl.”
The Lajkonik bus leaves Kraków Central Bus station (usually from the upstairs "G" bays, instead of the downstairs "D" bays). Some busses go directly to Auschwitz, after passing the Oświęcim train station (OŚWIĘCIM, Dworzec PKP): they usually say "Oświęcim, Auschwitz Museum". The trip takes about 90 minutes, but beware some routes take much longer (e.g. 2h30m).
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]
