As the number of prisoners grew, the camp expanded from the original barracks facility. Auschwitz II-Birkenau, in the nearby village in Brzezinka, underwent construction in October 1941 with the original purpose to house Soviet prisoners of war. Together with Polish inmates, Soviet soldiers were subjected to Zyklon B tests by the camp's SS commanders towards the end of 1941. Beginning in 1942, Jews in massive numbers began to be sent to the camp complex, along with thousands of Roma prisoners. The complex later expanded to include Auschwitz III-Monowitz in October 1942, a slave labor camp providing work for the I.G. Farben industrial complex nearby. By the middle of the war, Auschwitz had grown to include 40 sub-camps in neighboring towns in the region.
The commander of Auschwitz-Birkenau, Rudolf Höss, stated in his autobiography that in 1941 (no exact date is given) he was summoned to Berlin, where Himmler informed him that Hitler had issued an order to solve the “Jewish Question” for good, and that the order was to be implemented by the SS. “The existing extermination places in the east are unsuited to a large scale, long-term action. I have designated Auschwitz for this purpose,” Himmler said.
What is and what is not well written: It is likely that Frank’s opinions on the subject would have evolved if she had had the opportunity to age. Reading the diary as an adult, one sees the limitations of a teenager’s perspective, and longs for more. In one entry, Frank describes how her father’s business partners—now her family’s protectors—hold a critical corporate meeting in the office below the family’s hiding place. Her father, she and her sister discover that they can hear what is said by lying down with their ears pressed to the floor. In Frank’s telling, the episode is a comic one; she gets so bored that she falls asleep. But adult readers cannot help but ache for her father, a man who clawed his way out of bankruptcy to build a business now stolen from him, reduced to lying face-down on the floor just to overhear what his subordinates might do with his life’s work. When Anne Frank complains about her insufferable middle-aged roommate Fritz Pfeffer (Albert Dussel, per Frank’s pseudonym) taking his time on the toilet, adult readers might empathize with him as the only single adult in the group, permanently separated from his non-Jewish life partner whom he could not marry due to anti-Semitic laws. Readers Frank’s age connect with her budding romance with fellow hidden resident Peter van Pels (renamed Peter van Daan), but adults might wonder how either of the married couples in the hiding place managed their own relationships in confinement with their children. Readers Frank’s age relate to her constant complaints about grown-ups and their pettiness, but adult readers are equipped to appreciate the psychological devastation of Frank’s older subjects, how they endured not only their physical deprivation, but the greater blow of being reduced to a childlike dependence on the whims of others.
The Generalplan Ost ("General Plan for the East") called for deporting the population of occupied Eastern Europe and the Soviet Union to Siberia, for use as slave labour or to be murdered. To determine who should be killed, Himmler created the Volksliste, a system of classification of people deemed to be of German blood. He ordered that those of Germanic descent who refused to be classified as ethnic Germans should be deported to concentration camps, have their children taken away, or be assigned to forced labour. The plan also included the kidnapping of children deemed to have Aryan-Nordic traits, who were presumed to be of German descent. The goal was to implement Generalplan Ost after the conquest of the Soviet Union, but when the invasion failed Hitler had to consider other options. One suggestion was a mass forced deportation of Jews to Poland, Palestine, or Madagascar.
The first concentration camps in Germany were established soon after Hitler's appointment as chancellor in January 1933. In the weeks after the Nazis came to power, The SA (Sturmabteilungen; commonly known as Storm Troopers), the SS (Schutzstaffel; Protection Squadrons—the elite guard of the Nazi party), the police, and local civilian authorities organized numerous detention camps to incarcerate real and perceived political opponents of Nazi policy.
There were factions within the Nazi Party, both conservative and radical. The conservative Nazi Hermann Göring urged Hitler to conciliate with capitalists and reactionaries. Other prominent conservative Nazis included Heinrich Himmler and Reinhard Heydrich. Meanwhile, the radical Nazi Joseph Goebbels opposed capitalism, viewing it as having Jews at its core and he stressed the need for the party to emphasize both a proletarian and a national character. Those views were shared by Otto Strasser, who later left the Nazi Party in the belief that Hitler had allegedly betrayed the party's socialist goals by endorsing capitalism.
Oswald Spengler, a German cultural philosopher, was a major influence on Nazism, although after 1933 he became alienated from Nazism and was later condemned by the Nazis for criticising Adolf Hitler. Spengler's conception of national socialism and a number of his political views were shared by the Nazis and the Conservative Revolutionary movement. Spengler's views were also popular amongst Italian Fascists, including Benito Mussolini.
After September 1939, with the beginning of the Second World War, concentration camps became places where millions of ordinary people were enslaved as part of the war effort, often starved, tortured and killed. During the war, new Nazi concentration camps for "undesirables" spread throughout the continent. According to statistics by the German Ministry of Justice, about 1,200 camps and subcamps were run in countries occupied by Nazi Germany, while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe and that many of these camps were run for a limited amount of time before they were closed. Camps were being created near the centers of dense populations, often focusing on areas with large communities of Jews, Polish intelligentsia, Communists or Romani. Since millions of Jews lived in pre-war Poland, most camps were located in the area of the General Government in occupied Poland, for logistical reasons. The location also allowed the Nazis to quickly remove the German Jews from within Germany proper.
