Following the invasion of Poland, German occupation policy especially targeted the Jews but also brutalized non-Jewish Poles. In pursuit of lebensraum, Germany sought systematically to destroy Polish society and nationhood. The Nazis killed Polish priests and politicians, decimated the Polish leadership, and kidnapped the children of the Polish elite, who were raised as “voluntary Aryans” by their new German “parents.” Many Poles were also forced to perform hard labour on survival diets, were deprived of property and uprooted, and were interned in concentration camps.

On the evening of November 9, 1938, carefully orchestrated anti-Jewish violence “erupted” throughout the Reich, which since March had included Austria. Over the next 48 hours rioters burned or damaged more than 1,000 synagogues and ransacked and broke the windows of more than 7,500 businesses. Some 30,000 Jewish men between the ages of 16 and 60 were arrested and sent to concentration camps. Police stood by as the violence—often the action of neighbours, not strangers—occurred. Firemen were present not to protect the synagogues but to ensure that the flames did not spread to adjacent “Aryan” property. The pogrom was given a quaint name: Kristallnacht (“Crystal Night,” or “Night of Broken Glass”). In its aftermath, Jews lost the illusion that they had a future in Germany.
Then came the first American jeeps: a GI got out and opened the gate. Machine-gun fire burst from the center watchtower, the very one which since morning had been flying the white flag! The jeeps turned about and an armored tank came on. With a few bursts, it silenced the fire from the watchtower. The body of an SS man fell off the platform and came crashing loudly to the asphalt of the little square.
By 1943 it was evident to the armed forces leadership that Germany was losing the war.[358] The mass murder continued nevertheless, reaching a "frenetic" pace in 1944.[359] Auschwitz was gassing up to 6,000 Jews a day by spring that year.[360] On 19 March 1944, Hitler ordered the military occupation of Hungary and dispatched Eichmann to Budapest to supervise the deportation of the country's Jews.[361] From 22 March, Jews were required to wear the yellow star; forbidden from owning cars, bicycles, radios or telephones; then forced into ghettos.[362] From 15 May to 9 July, 440,000 Jews were deported from Hungary to Auschwitz-Birkenau, almost all to the gas chambers.[v] A month before the deportations began, Eichmann offered to exchange one million Jews for 10,000 trucks and other goods from the Allies, the so-called "blood for goods" proposal.[365] The Times called it "a new level of fantasy and self-deception".[366]
Part of Spielberg’s reluctance to make Schindler's List was that he didn’t feel that he was prepared or mature enough to tackle a film about the Holocaust. So he tried to recruit other directors to make the film. He first approached director Roman Polanski, a Holocaust survivor whose own mother was killed in Auschwitz. Polanski declined, but would go on to make his own film about the Holocaust, The Pianist, which earned him a Best Director Oscar in 2003. Spielberg then offered the movie to director Sydney Pollack, who also passed.

By mid-1944 those Jewish communities within easy reach of the Nazi regime had been largely exterminated,[367] in proportions ranging from about 25 percent in France[368] to more than 90 percent in Poland.[369] On 5 May Himmler claimed in a speech that "the Jewish question has in general been solved in Germany and in the countries occupied by Germany".[370] As the Soviet armed forces advanced, the camps in eastern Poland were closed down, with surviving inmates shipped to camps closer to Germany.[371] Efforts were made to conceal evidence of what had happened. The gas chambers were dismantled, the crematoria dynamited, and the mass graves dug up and the corpses cremated.[372] Local commanders continued to kill Jews, and to shuttle them from camp to camp by forced "death marches".[373] Already sick after months or years of violence and starvation, some were marched to train stations and transported for days at a time without food or shelter in open freight cars, then forced to march again at the other end to the new camp. Others were marched the entire distance to the new camp. Those who lagged behind or fell were shot. Around 250,000 Jews died during these marches.[374]
The anti-Hitler movement inside Germany, which included German communists and Jehovah's Witnesses, was the largest indigenous resistance movement of any country during the whole war. Only in Germany was an attempt made to assassinate their leader. Around 800,000 were sent to prison at one time or another for active resistance to the regime. While the western allies did all in their power to help other resistance movements, ie in France and the Netherlands, they did nothing to help or encourage the movement in Germany which in all probability could have ended the war sooner. But the Allies were intent on unconditional surrender and refused to make any deals at all with Germans. Accordingly the Allies viewed all Germans as bad, not only Nazis.
Uprisings broke out in some extermination camps. The few remaining Jews kept alive to dispose of bodies and sort possessions realised the number of transportees was reducing and they would be next. Civilian uprisings occurred across Poland as mainly young Jews, whose families had already been murdered, began to resist Nazi oppression. With reports of rebellion and mass murder in the British press, the situation in the camps could no longer be be ignored.
In order to gain a more personal perspective on the film, Spielberg traveled to Poland before principal photography began to interview Holocaust survivors and visit the real-life locations that he planned to portray in the movie. While there, he visited the former Gestapo headquarters on Pomorska Street, Schindler’s actual apartment, and Amon Goeth’s villa.
In early April 2009, a carbon copy of one version of the list was discovered at the State Library of New South Wales by workers combing through boxes of materials collected by author Thomas Keneally. The 13-page document, yellow and fragile, was filed among research notes and original newspaper clippings. The document was given to Keneally in 1980 by Pfefferberg when he was persuading him to write Schindler's story. This version of the list contains 801 names and is dated 18 April 1945; Pfefferberg is listed as worker number 173. Several authentic versions of the list exist, because the names were re-typed several times as conditions changed in the hectic days at the end of the war.[103]

The prisoners of Dachau concentration camp originally were to serve as forced labor for a munition factory, and to expand the camp. It was used as a training center for SS guards and was a model for other concentration camps.[28] The camp was about 300 m × 600 m (1,000 ft × 2,000 ft) in rectangular shape. The prisoners' entrance was secured by an iron gate with the motto "Arbeit macht frei" ("Work will make you free"). This reflected Nazi propaganda, which trivialized concentration camps as labor and re-education camps, when in fact forced labor was used as a method of torture and murder.[29]

At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents,[293] releasing toxic prussic acid, or hydrogen cyanide.[294] Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.[295] Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives."[296] The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut.[297] The work was done by the Sonderkommando, work groups of mostly Jewish prisoners.[298] At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.[299]
The staff consisted of a chief, several assistants and a group of clerks. The office maintained files which contained all personal data pertinent to the allocation of individuals for work of various kinds. The three main sources of employment at Dachau were (a) work inside the camp, (b) work at the SS camp, (c) work in farms and in factories in the area. The lists of people to be shipped off on transports was usually compiled from those prisoners who were not part of a regular "Working Commando."
When asked, Schindler told that his metamorphosis during the war was sparked by the shocking immensity of the Final Solution. In his own words: "I hated the brutality, the sadism, and the insanity of Nazism. I just couldn't stand by and see people destroyed. I did what I could, what I had to do, what my conscience told me I must do. That's all there is to it. Really, nothing more."

In the weeks that followed liberation, the British burnt down the typhus - infested barracks in the concentration camp at Bergen Belsen. They transferred the former prisoners who had not died in the weeks that followed liberation to the military camp, where there were better living conditions. Many survivors remained at Bergen Belsen after liberation, because they did not want to return to their homes or because they had no homes to return to. The British registered these survivors, and Bergen Belsen began to operate as a DP (Displaced Persons) camp for them. Many Jews who survived other Nazi camps, or who survived the Holocaust in hiding or by fleeing to the Soviet Union, moved to the DP camp at Bergen Belsen.

Eleven of the defendants were sentenced to death.[28] They included Kramer, Volkenrath and Klein. The executions by hanging took place on December 13, 1945 in Hamelin.[28] Fourteen defendants were acquitted (one was excluded from the trial due to illness). Of the remaining 19, one was sentenced to life in prison but he was executed for another crime. Eighteen were sentenced to prison for periods of one to 15 years; however, most of these sentences were subsequently reduced significantly on appeals or pleas for clemency.[28] By June 1955, the last of those sentenced in the Belsen trial had been released.[20]:37 Nine other members of the Belsen personnel were tried by later military tribunals in 1946 and 1948.[28]
Compared to the appalling number of men, women and children killed at the Nazi extermination camps—places like Sobibor, Chelmno, Treblinka and others where, cumulatively, millions perished—the death toll at the Bergen-Belsen concentration camp in northwest Germany was (a horrible thing to say!) relatively small. More than a million people were killed at Auschwitz-Birkenau alone; at Belsen, by most estimates, fewer than 100,000 died—from starvation and disease (typhus, for example), as well as outright slaughter.
In March 1944, part of the camp was redesignated as an Erholungslager ("recovery camp"),[11] where prisoners too sick to work were brought from other concentration camps. They were in Belsen supposedly to recover and then return to their original camps and resume work, but many of them died in Belsen of disease, starvation, exhaustion and lack of medical attention.[12]
