When Germany invaded Poland in September 1939, it gained control of about 2 million Jews in the occupied territory. The rest of Poland was occupied by the Soviet Union, which had control of the rest of Poland's pre-war population of 3.3–3.5 million Jews.[141] German plans for Poland included expelling gentile Poles from large areas, confining Jews, and settling Germans on the emptied lands.[142] The Germans initiated a policy of sending Jews from all territories they had recently annexed (Austria, Czechoslovakia, and western Poland) to the central section of Poland, which they called the General Government. There, the Jews were concentrated in ghettos in major cities,[143] chosen for their railway lines to facilitate later deportation.[144] Food supplies were restricted, public hygiene was difficult, and the inhabitants were often subjected to forced labor.[145] In the work camps and ghettos, at least half a million Jews died of starvation, disease, and poor living conditions.[146] Jeremy Black writes that the ghettos were not intended, in 1939, as a step towards the extermination of the Jews. Instead, they were viewed as part of a policy of creating a territorial reservation to contain them.[147][l]
In nearly every country overrun by the Nazis, the Jews were forced to wear badges marking them as Jews, they were rounded up into ghettos or concentration camps and then gradually transported to the killing centers. The death camps were essentially factories for murdering Jews. The Germans shipped thousands of Jews to them each day. Within a few hours of their arrival, the Jews had been stripped of their possessions and valuables, gassed to death, and their bodies burned in specially designed crematoriums. Approximately 3.5 million Jews were murdered in these death camps.
On May 8, 1945, the war in Europe ended, and the next day Schindler and his wife fled the country with the help of several of the Schindlerjuden, as the Jews he saved came to be known. Schindler was wanted for war crimes in Czechoslovakia due to his earlier espionage activities. In 1949 they settled in Argentina with several of the Jewish families they had saved. Having spent the bulk of his profiteering fortune on bribes, Schindler unsuccessfully attempted to farm. He went bankrupt in 1957 and the next year traveled alone to West Germany, where he made an abortive entry into the cement business. Schindler spent the rest of his life supported by donations from the Schindlerjuden. He was named a Righteous Gentile by Yad Vashem in 1962 and was interred in the Catholic cemetery on Mount Zion in Jerusalem.
Despite, wide reporting of Holocaust atrocities including gas chambers, many prominent analysts doubted the authenticity of these reports. Prominently, Roger Allen, a member of the British Foreign Office discounted intelligence reports on the use of gas chambers in Polish extermination camps because he could “never understand what the advantage of a gas chamber over a simple machine gun or over starving people would be.”
On 4 September 2003, despite a protest from the museum, three Israeli Air Force F-15 Eagles performed a fly-over of Auschwitz II-Birkenau during a ceremony at the camp below. All three pilots were descendants of Holocaust survivors, including the man who led the flight, Major-General Amir Eshel.[297] On 27 January 2015, some 300 Auschwitz survivors gathered with world leaders under a giant tent at the entrance to Auschwitz II to commemorate the 70th anniversary of the camp's liberation.[298][i]

On 15 October 1944 a train carrying 700 men on Schindler's list was initially sent to the concentration camp at Gross-Rosen, where the men spent about a week before being re-routed to the factory in Brünnlitz.[66] Three hundred female Schindlerjuden were similarly sent to Auschwitz, where they were in imminent danger of being sent to the gas chambers. Schindler's usual connections and bribes failed to obtain their release. Finally after he sent his secretary, Hilde Albrecht, with bribes of black market goods, food and diamonds, the women were sent to Brünnlitz after several harrowing weeks in Auschwitz.[67]
“I suddenly see Steinlauf, my friend aged almost fifty, with nude chest, scrub his neck and shoulders with little success (he has no soap) [He] sees me and asks me severely why I do not wash. Why should I wash? Would I be better off than I am? Would I please someone more? Would I live a day longer?…. Does Steinlauf not know that after half an hour with the coal sacks every difference between him and me will have disappeared?….
The Nazis considered Jews to be the main danger to Germany. Jews were the primary victims of Nazi racism, but other victims included Roma (Gypsies) and people with mental or physical disabilities. The Nazis murdered some 200,000 Roma. And they murdered at least 250,000 mentally or physically disabled patients, mainly German and living in institutions, in the so-called Euthanasia Program.

The first 'bunker', with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra 'capacity' was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the 'bunkers' were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open. Between January 1942 and March 1943, 175,000 Jews were gassed to death here, of whom 105,000 were killed from January to March 1943.
Finland was pressured in 1942 to hand over its 150–200 non-Finnish Jews to Germany. After opposition from the government and public, eight non-Finnish Jews were deported in late 1942; only one survived the war.[173] Japan had little antisemitism in its society and did not persecute Jews in most of the territories it controlled. Jews in Shanghai were confined, but despite German pressure they were not killed.[174]
Schindler first arrived in Kraków in October 1939, on Abwehr business, and took an apartment the following month. Emilie maintained the apartment in Ostrava and visited Oskar in Kraków at least once a week.[18][19] In November 1939, he contacted interior decorator Mila Pfefferberg to decorate his new apartment. Her son, Leopold "Poldek" Pfefferberg, soon became one of his contacts for black market trading. They eventually became lifelong friends.[20]
