Most Holocaust historians define the Holocaust as the enactment, between 1941 and 1945, of the German state policy to exterminate the European Jews.[a] In Teaching the Holocaust (2015), Michael Gray, a specialist in Holocaust education,[27] offers three definitions: (a) "the persecution and murder of Jews by the Nazis and their collaborators between 1933 and 1945", which views the events of Kristallnacht in Germany in 1938 as an early phase of the Holocaust; (b) "the systematic mass murder of the Jews by the Nazi regime and its collaborators between 1941 and 1945", which acknowledges the shift in German policy in 1941 toward the extermination of the Jewish people in Europe; and (c) "the persecution and murder of various groups by the Nazi regime and its collaborators between 1933 and 1945", which includes all the Nazis' victims. The third definition fails, Gray writes, to acknowledge that only the Jewish people were singled out for annihilation.[28]
"The persecution of Jews in occupied Poland meant that we could see horror emerging gradually in many ways. In 1939, they were forced to wear Jewish stars, and people were herded and shut up into ghettos. Then, in the years '41 and '42 there was plenty of public evidence of pure sadism. With people behaving like pigs, I felt the Jews were being destroyed. I had to help them. There was no choice."

^ Nothing appeared in Luftwaffe 'doctrine' stipulating "terror" as a major operational factor. The method of "terror", was denied to German aerial operations (and strategic bombing methods) by the Luftwaffe field manual The Conduct of Air Operations, Regulation 16, issued in 1935 (Corum 1992, pp. 167–169). Regulation 16 denied "terror" operations against civilians, and it was not until 1942 when indiscriminate "terror" operations, in which terror and civilian casualties become the primary target, took place (Corum 1997, pp. 7, 143).

However, Schindler's financial woes continued, and he went bankrupt in 1958. He left his wife Emilie in Argentina to find fortune back in Germany, but despite his efforts, his various businesses repeatedly failed. Again, he had to depend on the charity of the Schindler Jews, many of whom he was still in contact with, to support his well being. In 1963, the same year he declared bankruptcy, he was honored by the State of Israel as Righteous Among the Nations, an award for non Jews who helped save Jews during the Holocaust. A year later, he had a heart attack and spent time recuperating in a hospital.

On 31 July 1941, Hermann Göring gave written authorization to Reinhard Heydrich, Chief of the Reich Security Head Office (RSHA), to prepare and submit a plan for Die Endlösung der Judenfrage (the Final Solution of the Jewish question) in territories under German control and to coordinate the participation of all involved government organizations.[152] Plans for the extermination of the European Jews—eleven million people—were formalized at the Wannsee Conference in Berlin on 20 January 1942. Some would be worked to death and the rest killed.[153] Initially the victims were killed with gas vans or by Einsatzgruppen firing squads, but these methods were impractical for an operation of this scale.[154] By 1942, killing centers at Auschwitz, Sobibór, Treblinka, and other extermination camps had become the primary method of mass killing.[155]
In 1939, shortly after the war began, the Germans initiated the T4 Program—framed euphemistically as a “euthanasia” program—for the murder of intellectually or physically disabled and emotionally disturbed Germans who by their very existence violated the Nazi ideal of Aryan supremacy. They were termed “life unworthy of life.” An economic justification was also employed as these Germans were considered “useless eaters.” The Nazis pioneered the use of gas chambers and mass crematoria under this program. The murder of the disabled was the training ground for key personnel who were to later staff the death camps of Aktion Reinhard. The German public protested these murders. The Roman Catholic bishop of Münster, Clemens August, Graf von Galen, preached against them, and the T4 program was formally halted. Nonetheless, the murder and sterilization of these German “Aryans” continued secretly throughout the war.
The first such extermination camps were introduced during Operation Reinhardt, which targeted the elimination of the Jewish people within the General Government of Occupied Poland and Ukraine. After the first killing center open at Chelmno, the use of these extermination tactics spread quickly. At the height of deportations, the Birkenau killing center murdered 6,000 Jews a day.
Though Spielberg is already an extremely wealthy man as a result of the many big-budget movies that have made him one of Hollywood’s most successful directors, he decided that a story as important as Schindler’s List shouldn’t be made with an eye toward financial reward. The director relinquished his salary for the movie and any proceeds he would stand to make in perpetuity, calling any such personal gains “blood money.” Instead, Spielberg used the film’s profits to found the USC Shoah Foundation, which was established in 1994 to honor and remember the survivors of the Holocaust by collecting personal recollections and audio visual interviews.
Schindler joined the separatist Sudeten German Party in 1935.[6] Although he was a citizen of Czechoslovakia, Schindler became a spy for the Abwehr, the military intelligence service of Nazi Germany, in 1936. He was assigned to Abwehrstelle II Commando VIII, based in Breslau.[7] He later told Czech police that he did it because he needed the money; by this time Schindler had a drinking problem and was chronically in debt.[8]
