In 1942, after the death of Armaments Minister Fritz Todt, Hitler appointed Albert Speer as his replacement. Wartime rationing of consumer goods led to an increase in personal savings, funds which were in turn lent to the government to support the war effort. By 1944, the war was consuming 75 percent of Germany's gross domestic product, compared to 60 percent in the Soviet Union and 55 percent in Britain. Speer improved production by centralising planning and control, reducing production of consumer goods, and using forced labour and slavery. The wartime economy eventually relied heavily upon the large-scale employment of slave labour. Germany imported and enslaved some 12 million people from 20 European countries to work in factories and on farms. Approximately 75 percent were Eastern European. Many were casualties of Allied bombing, as they received poor air raid protection. Poor living conditions led to high rates of sickness, injury, and death, as well as sabotage and criminal activity. The wartime economy also relied upon large-scale robbery, initially through the state seizing the property of Jewish citizens and later by plundering the resources of occupied territories.
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.
Primo Levi suggested Anne Frank is frequently identified as a single representative of the millions of people who suffered and died as she did because "One single Anne Frank moves us more than the countless others who suffered just as she did but whose faces have remained in the shadows. Perhaps it is better that way; if we were capable of taking in all the suffering of all those people, we would not be able to live." In her closing message in Müller's biography of Anne Frank, Miep Gies expressed a similar thought, though she attempted to dispel what she felt was a growing misconception that "Anne symbolises the six million victims of the Holocaust", writing: "Anne's life and death were her own individual fate, an individual fate that happened six million times over. Anne cannot, and should not, stand for the many individuals whom the Nazis robbed of their lives ... But her fate helps us grasp the immense loss the world suffered because of the Holocaust."
Construction of crematorium I began at Auschwitz I at the end of June or beginning of July 1940. Initially intended not for mass murder but for prisoners who had been executed or had otherwise died in the camps, the crematorium was in operation from August 1940 until July 1943, by which time the crematoria at Auschwitz II had taken over. By May 1942 three ovens had been installed in crematorium I, which together could burn 340 bodies in 24 hours.
In January 1923, France occupied the Ruhr industrial region as a result of Germany's failure to meet its reparations payments. This led to economic chaos, the resignation of Wilhelm Cuno's government and an attempt by the German Communist Party (KPD) to stage a revolution. The reaction to these events was an upsurge of nationalist sentiment. Nazi Party membership grew sharply to about 20,000. By November, Hitler had decided that the time was right for an attempt to seize power in Munich, in the hope that the Reichswehr (the post-war German military) would mutiny against the Berlin government and join his revolt. In this, he was influenced by former General Erich Ludendorff, who had become a supporter—though not a member—of the Nazis.
Although he opposed communist ideology, Hitler publicly praised the Soviet Union's leader Joseph Stalin and Stalinism on numerous occasions. Hitler commended Stalin for seeking to purify the Communist Party of the Soviet Union of Jewish influences, noting Stalin's purging of Jewish communists such as Leon Trotsky, Grigory Zinoviev, Lev Kamenev and Karl Radek. While Hitler had always intended to bring Germany into conflict with the Soviet Union so he could gain Lebensraum ("living space"), he supported a temporary strategic alliance between Nazi Germany and the Soviet Union to form a common anti-liberal front so they could defeat liberal democracies, particularly France.
When the Nazis came to power in Germany, they quickly moved to suppress all real and potential opposition. The general public was intimidated by the arbitrary psychological terror that was used by the special courts (Sondergerichte). Especially during the first years of their existence when these courts "had a strong deterrent effect" against any form of political protest.
