After examining several sites for a new plant to manufacture Buna-N, a type of synthetic rubber essential to the war effort, the German chemical cartel IG Farben chose a site near the towns of Dwory and Monowice (Monowitz in German), about 7 kilometres (4.3 mi) east of Auschwitz I.[50] Tax exemptions were available to corporations prepared to develop industries in the frontier regions under the Eastern Fiscal Assistance Law, passed in December 1940. The site had good railway connections and access to raw materials.[51] In February 1941, Himmler ordered that the Jewish population of Oświęcim be expelled to make way for skilled laborers; that all Poles able to work remain in the town and work on building the factory; and that Auschwitz prisoners be used in the construction work.[52]

The Hitler cabinet used the terms of the Reichstag Fire Decree and later the Enabling Act to initiate the process of Gleichschaltung ("co-ordination"), which brought all aspects of life under party control.[25] Individual states not controlled by elected Nazi governments or Nazi-led coalitions were forced to agree to the appointment of Reich Commissars to bring the states in line with the policies of the central government. These Commissars had the power to appoint and remove local governments, state parliaments, officials, and judges. In this way Germany became a de facto unitary state, with all state governments controlled by the central government under the NSDAP.[26][27] The state parliaments and the Reichsrat (federal upper house) were abolished in January 1934,[28] with all state powers being transferred to the central government.[27]

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.[321] To determine who should be killed, Himmler created the Volksliste, a system of classification of people deemed to be of German blood.[322] 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.[323][324] The plan also included the kidnapping of children deemed to have Aryan-Nordic traits, who were presumed to be of German descent.[325] 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.[321][326] One suggestion was a mass forced deportation of Jews to Poland, Palestine, or Madagascar.[317]
During the first half of July, Anne and her family hid in an apartment that would eventually hide four Dutch Jews as well—Hermann, Auguste, and Peter van Pels, and Fritz Pfeffer. For two years, they lived in a secret attic apartment behind the office of the family-owned business at 263 Prinsengracht Street, which Anne referred to in her diary as the Secret Annex. Otto Frank's friends and colleagues, Johannes Kleiman, Victor Kugler, Jan Gies, and Miep Gies, had helped to prepare the hiding place and smuggled food and clothing to the Franks at great risk to their own lives.

On a nearby table sat the second horn part to Tchaikovsky’s Capriccio Italien (Op. 45), which had been played by the death camp’s orchestra. Ms. Jastrzebiowska would preserve the page as it was, she said, and keep the smudges showing that the pages had been turned. “The objects must show their own history,” said Jolanta Banas-Maciaszczyk, 36, the leader of the preservation department.

On the night of 8 November, the Nazis used a patriotic rally in a Munich beer hall to launch an attempted putsch ("coup d'état"). This so-called Beer Hall Putsch attempt failed almost at once when the local Reichswehr commanders refused to support it. On the morning of 9 November, the Nazis staged a march of about 2,000 supporters through Munich in an attempt to rally support. Troops opened fire and 16 Nazis were killed. Hitler, Ludendorff and a number of others were arrested and were tried for treason in March 1924. Hitler and his associates were given very lenient prison sentences. While Hitler was in prison, he wrote his semi-autobiographical political manifesto Mein Kampf ("My Struggle").
Auschwitz became a significant source of slave labor locally and functioned as an international clearing house. Of 2.5 million people who were deported to Auschwitz, 405,000 were given prisoner status and serial numbers. Of these, approximately 50 percent were Jews and 50 percent were Poles and other nationalities. Of those who received numbers, 65,000 survived. It is estimated that about 200,000 people passed through the Auschwitz camps and survived.
After his daughter’s writings were returned to him, Otto Frank helped compile them into a manuscript that was published in the Netherlands in 1947 under the title “Het Acheterhuis” (“Rear Annex”). Although U.S. publishers initially rejected the work as too depressing and dull, it was eventually published in America in 1952 as “The Diary of a Young Girl.” The book, which went on to sell tens of millions of copies worldwide, has been labeled a testament to the indestructible nature of the human spirit. It is required reading at schools around the globe and has been adapted for the stage and screen.

The concentration camps increasingly became sites where the SS authorities could kill targeted groups of real or perceived enemies of Nazi Germany. They also came to serve as holding centers for a rapidly growing pool of forced laborers used for SS construction projects, SS-commissioned extractive industrial sites, and, by 1942, the production of armaments, weapons, and related goods for the German war effort.

Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.

Nazi Germany maintained concentration camps (German: Konzentrationslager, KZ or KL) throughout the territories it controlled before and during the Second World War. The first Nazi camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control of the police by Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring.[2] Used to hold and torture political opponents and union organizers, the camps initially held around 45,000 prisoners.[3] In 1933–1939, before the onset of war, most prisoners consisted of German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans.[4]
