As the Russians closed in on Auschwitz, the Germans became desperate, destroying as much evidence of war crimes as they could, including records and property seized from prisoners, and forcing as many prisoners as they could on what became death marches. The day before the Russian Army liberated Auschwitz, Edith died there. On January 27 Otto was liberated and taken to Odessa and then France before being allowed to return to Amsterdam in June 1945.
Selections for transit were a regular feature at Westerbork. Each Monday evening a train of about 20 cattle wagons would arrive at the camp. A list of one thousand people would be compiled by the Jewish council, which was made up of leaders of the community appointed by the Nazis and forced to carry out the Nazis’ orders. Early on the Tuesday morning those selected would assemble for deportation. After a roll call, they would enter the trains, at least 50 to each wagon, a bucket of water at one end and an empty one for use as a toilet at the other. The doors would close before the train departed for the long journey to the intended destination.
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[71] and some Wall Street figures were allegedly involved,[72] but many other businessmen were suspicious of the extreme nationalist tendencies of the Nazis and preferred to support the traditional conservative parties instead.[73]
Historians regard the equation of National Socialism as 'Hitlerism' as too simplistic since the term was used prior to the rise of Hitler and the Nazis and the different ideologies incorporated into Nazism were already well established in certain parts of German society before World War I.[27] The Nazis were strongly influenced by the post–World War I far-right in Germany, which held common beliefs such as anti-Marxism, anti-liberalism and antisemitism, along with nationalism, contempt for the Treaty of Versailles and condemnation of the Weimar Republic for signing the armistice in November 1918 which later led it to sign the Treaty of Versailles.[28] A major inspiration for the Nazis were the far-right nationalist Freikorps, paramilitary organizations that engaged in political violence after World War I.[28] Initially, the post–World War I German far-right was dominated by monarchists, but the younger generation, which was associated with Völkisch nationalism, was more radical and it did not express any emphasis on the restoration of the German monarchy.[29] This younger generation desired to dismantle the Weimar Republic and create a new radical and strong state based upon a martial ruling ethic that could revive the "Spirit of 1914" which was associated with German national unity (Volksgemeinschaft).[29]
After moving to Amsterdam, Anne and Margot Frank were enrolled in school—Margot in public school and Anne in a Montessori school. Margot demonstrated ability in arithmetic, and Anne showed aptitude for reading and writing. Anne's friend, Hanneli Goslar, later recalled that from early childhood, Frank frequently wrote, although she shielded her work with her hands and refused to discuss the content of her writing.
The process of losing any kind of hope was a very gradual one. We were transported in cattle wagons in which many babies and children suffocated, in what it turned out was the last transport of Hungarians. We had no water, no food, there was no hygiene. That diminished our hope and increased the feeling of being trapped. But despite that, you always retained a glimmer of hope. Always.
Most Germans were relieved that the conflicts and street fighting of the Weimar era had ended. They were deluged with propaganda orchestrated by Minister of Public Enlightenment and Propaganda Joseph Goebbels, who promised peace and plenty for all in a united, Marxist-free country without the constraints of the Versailles Treaty.[44] The NSDAP obtained and legitimised power through its initial revolutionary activities, then through manipulation of legal mechanisms, the use of police powers, and by taking control of the state and federal institutions.[45][46] The first major Nazi concentration camp, initially for political prisoners, was opened at Dachau in 1933.[47] Hundreds of camps of varying size and function were created by the end of the war.[48]

The gas chambers in the Auschwitz complex constituted the largest and most efficient extermination method employed by the Nazis. Four chambers were in use at Birkenau, each with the potential to kill 6,000 people daily. They were built to look like shower rooms in order to confuse the victims. New arrivals at Birkenau were told that they were being sent to work, but first needed to shower and be disinfected. They would be led into the shower-like chambers, where they were quickly gassed to death with the highly poisonous Zyklon B gas.

From the end of March 1942, Jewish transports from Nazi-ruled countries flowed into Auschwitz. Jews from Slovakia and France were deported there first, followed by Dutch Jews from July 1942, and from August, Jews from Belgium and Yugoslavia. Between October 1942 and October 1944, over 46 000 prisoners were deported from Terezín to Auschwitz. Some of them were put in the „Terezín family camp“ for a temporary period. Throughout 1943, transports were sent to Auschwitz from Germany and other countries in the Nazi sphere of power. The victims of the last great wave of deportations to Auschwitz were the Jews of Hungary, who were deported between May and July 1944.

By 1940, the CCI came under the control of the Verwaltung und Wirtschaftshauptamt Hauptamt (VuWHA; Administration and Business office) which was set up under Oswald Pohl.[25] Then in 1942, the CCI became Amt D (Office D) of the consolidated main office known as the SS-Wirtschafts-Verwaltungshauptamt (SS Economic and Administrative Department; WVHA) under Pohl.[25] In 1942, the SS built a network of extermination camps to systematically kill millions of prisoners by gassing. The extermination camps (Vernichtungslager) and death camps (Todeslager) were camps whose primary function was genocide. The Nazis themselves distinguished the concentration camps from the extermination camps.[26][27] The British intelligence service had information about the concentration camps, and in 1942 Jan Karski delivered a thorough eyewitness account to the government.
