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.
In November 1938 a young Jewish man requested an interview with the German ambassador in Paris and met with a legation secretary, whom he shot and killed to protest his family's treatment in Germany. This incident provided the pretext for a pogrom the NSDAP incited against the Jews on 9 November 1938. Members of the SA damaged or destroyed synagogues and Jewish property throughout Germany. At least 91 German Jews were killed during this pogrom, later called Kristallnacht, the Night of Broken Glass. Further restrictions were imposed on Jews in the coming months – they were forbidden to own businesses or work in retail shops, drive cars, go to the cinema, visit the library, or own weapons, and Jewish pupils were removed from schools. The Jewish community was fined one billion marks to pay for the damage caused by Kristallnacht and told that any insurance settlements would be confiscated. By 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Argentina, Great Britain, Palestine, and other countries. Many chose to stay in continental Europe. Emigrants to Palestine were allowed to transfer property there under the terms of the Haavara Agreement, but those moving to other countries had to leave virtually all their property behind, and it was seized by the government.
The concept of the Aryan race, which the Nazis promoted, stems from racial theories asserting that Europeans are the descendants of Indo-Iranian settlers, people of ancient India and ancient Persia. Proponents of this theory based their assertion on the fact that words in European languages and words in Indo-Iranian languages have similar pronunciations and meanings. Johann Gottfried Herder argued that the Germanic peoples held close racial connections to the ancient Indians and the ancient Persians, who he claimed were advanced peoples that possessed a great capacity for wisdom, nobility, restraint and science. Contemporaries of Herder used the concept of the Aryan race to draw a distinction between what they deemed to be "high and noble" Aryan culture versus that of "parasitic" Semitic culture.
The fate of the Frank family and other Jews in Amsterdam was wrapped up with the German occupation of the city, which began in May 1940. In July 1942, German authorities and their Dutch collaborators began to concentrate Jews from throughout the Netherlands at Westerbork, a transit camp near the Dutch town of Assen, not far from the German border. From Westerbork, German officials deported the Jews to Auschwitz-Birkenau and Sobibor killing centers in German-occupied Poland.
The 1930 elections changed the German political landscape by weakening the traditional nationalist parties, the DNVP and the DVP, leaving the Nazis as the chief alternative to the discredited Social Democrats and the Zentrum, whose leader, Heinrich Brüning, headed a weak minority government. The inability of the democratic parties to form a united front, the self-imposed isolation of the Communists and the continued decline of the economy, all played into Hitler's hands. He now came to be seen as de facto leader of the opposition and donations poured into the Nazi Party's coffers. Some major business figures, such as Fritz Thyssen, were Nazi supporters and gave generously and some Wall Street figures were allegedly involved, but many other businessmen were suspicious of the extreme nationalist tendencies of the Nazis and preferred to support the traditional conservative parties instead.
The failure of the factory, as Wachsmann describes it, was indicative of the incompetence of the S.S. and the inconsistency of its vision for the camps. To turn prisoners into effective laborers would have required giving them adequate food and rest, not to mention training and equipment. It would have meant treating them like employees rather than like enemies. But the ideological momentum of the camps made this inconceivable. Labor was seen as a punishment and a weapon, which meant that it had to be extorted under the worst possible circumstances. Prisoners were made to build the factory in the depths of winter, with no coats or gloves, and no tools. “Inmates carried piles of sand in their uniforms,” Wachsmann writes, while others “moved large mounds of earth on rickety wooden stretchers or shifted sacks of cement on their shoulders.” Four hundred and twenty-nine prisoners died and countless more were injured, yet in the end not a single brick was produced.
Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35. Himmler expanded the role of the camps to hold so-called "racially undesirable elements", such as Jews, Gypsies/Romanis/Sintis, Serbs, Poles, disabled people, and criminals. The number of people in the camps, which had fallen to 7,500, grew again to 21,000 by the start of World War II and peaked at 715,000 in January 1945.
