Schindler’s profits were extraordinarily high because he used low-paid Jewish workers from the ghetto the Nazis established in the city. During the war, many industrialists like Schindler used the forced labor of Jews living in Nazi ghettos or concentration camps. Major German companies, including Volkswagen, Bayer, and IG Farben, the largest chemical company in the world at the time, profited handsomely from coerced labor. This labor often occurred in the worst conditions possible, and many workers died as a result of being subjected to excessively long, arduous work shifts without adequate food.
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."
From the evidence it became clear how this was done. After a sleepless night – for sleep in the huts was impossible – the men were driven to a hut where the dead were collected. They were instructed by what the witness called the “language of blows, which was universal.” Their duty was to take strips of blankets, tie them to a corpse, and, four men to a corpse, drag it across the main road of the camp along dusty paths to the burial pit. In the midst of this work, which lasted three days without sleep, food, or water till the British arrived, one Hungarian guard at the exit from the hut containing the bodies began shooting all prisoners if they did not come out dragging a body at the double. During the last three days the Hungarian guards were almost continuously shooting at prisoners, sometimes single shots, sometimes fusillades.
Historians increasingly view the Holocaust as a pan-European phenomenon, or a series of holocausts impossible to conduct without the help of local collaborators. Over 200,000 people are estimated to have been Holocaust perpetrators; without them, the Germans would not have been able to extend the Holocaust across most of Europe. Some Christian churches tried to defend the Jews by declaring that converted Jews were "part of the flock," according to Saul Friedländer, "but even then only up to a point". Otherwise, Friedländer writes, "[n]ot one social group, not one religious community, not one scholarly institution or professional association in Germany and throughout Europe declared its solidarity with the Jews."
On March 22, 1933, a few weeks after Adolf Hitler had been appointed Reich Chancellor, a concentration camp for political prisoners was set up in Dachau. This camp served as a model for all later concentration camps and as a "school of violence" for the SS men under whose command it stood. In the twelve years of its existence over 200.000 persons from all over Europe were imprisoned here and in the numerous subsidary camps. 41.500 were murdered. On April 29 1945, American troops liberated the survivors.
The industrialization and scale of the murder was unprecedented. Killings were systematically conducted in virtually all areas of occupied Europe—more than 20 occupied countries. Close to three million Jews in occupied Poland and between 700,000 and 2.5 million Jews in the Soviet Union were killed. Hundreds of thousands more died in the rest of Europe. Victims were transported in sealed freight trains from all over Europe to extermination camps equipped with gas chambers. The stationary facilities grew out of Nazi experiments with poison gas during the Aktion T4 mass murder ("euthanasia") programme against the disabled and mentally ill, which began in 1939. The Germans set up six extermination camps in Poland: Auschwitz II-Birkenau (established October 1941); Majdanek (October 1941); Chełmno (December 1941); and the three Operation Reinhard camps, Belzec, Sobibor, and Treblinka, in 1942. A seventh death camp, Maly Trostenets, was established near Minsk in Belarus, then part of the Reichskommissariat Ostland. Discussions at the Wannsee Conference in January 1942 made it clear that the German "final solution of the Jewish question" was intended eventually to include Britain and all the neutral states in Europe, including Ireland, Switzerland, Turkey, Sweden, Portugal, and Spain.
German-occupied Denmark rescued most of its own Jews by spiriting them to Sweden by sea in October 1943. This was possible partly because the German presence in Denmark was relatively small. Moreover, while anti-Semitism in the general population of many other countries led to collaboration with the Germans, Jews were an integrated part of Danish culture. Under these unique circumstances, Danish humanitarianism flourished.
After 1945 the name was applied to the displaced persons camp established nearby, but it is most commonly associated with the concentration camp. From 1941 to 1945, almost 20,000 Soviet prisoners of war and a further 50,000 inmates died there. Overcrowding, lack of food and poor sanitary conditions caused outbreaks of typhus, tuberculosis, typhoid fever and dysentery, leading to the deaths of more than 35,000 people in the first few months of 1945, shortly before and after the liberation.
