Before beginning Jewish exterminations, though, the Nazi’s used the Soviet POWs at the Auschwitz camp in trials of the poison gas Zyklon-B, produced by the German company “Degesch” (Deutsche Gesellschaft zur Schädlingsbekämpfung), which was marked as the best way to kill many people at once. The POWs were gassed in underground cells in Block 11, the so called “Death Block,” and following these trials, one gas chamber was setup just outside the main camp and two temporary gas chambers were opened at Birkenau.
In Germany the words 'protective custody' have a double meaning. Originally the term meant the incarceration of people who were threatened by others and who were guarded for their own safety so that they might be protected from their enemies. Now, however, men in protective custody are mostly those who are brought, for the 'protection of the people and the State,' into a concentration camp without hearing, without court sentence, without the possibility of redress, and for an indefinite time. Frequently people sentenced by a court are taken into protective custody by the Gestapo after serving their prison sentence, often directly from the prison gate. Such, for example, was the fate of Pastor Niemöller, who, after being released from prison, was taken into the camp Sachsenhausen near Oranienburg, the camp with which we shall be concerned here. He is in solitary confinement there, and I never saw him.

In 1999, Time named Anne Frank among the heroes and icons of the 20th century on their list The Most Important People of the Century, stating: "With a diary kept in a secret attic, she braved the Nazis and lent a searing voice to the fight for human dignity".[91] Philip Roth called her the "lost little daughter" of Franz Kafka.[116] Madame Tussauds wax museum unveiled an exhibit featuring a likeness of Anne Frank in 2012.[117] Asteroid 5535 Annefrank was named in her honour in 1995, after having been discovered in 1942.[118]
In June 1945 the Soviet authorities took over Auschwitz I and converted it into a POW camp for German prisoners. The hospital had to move beyond the camp perimeter into former administrative buildings, where it functioned until October 1945.[254] Many of the barracks at Birkenau were taken apart by civilians, who used the materials to rebuild their own homes, which had been levelled out in the construction of Auschwitz II. The poorest residents sifted the crematoria ashes in search of nuggets from melted gold, before warning shots were fired.[255] The POW camp for German prisoners of war was used until 1947 by the Soviet NKVD (People's Commissariat for Internal Affairs).[256] The NKVD and its Polish counterpart, the MBP, used the Auschwitz Neu-Dachs sub-camp at Jaworzno to the north of Oświęcim as a concentration camp from 1945 to 1956.[257] The Soviets dismantled and exported the IG Farben factories to the USSR.[258] Meanwhile, Soviet and Polish investigators worked to document the war crimes of the SS.[259] After the site became a museum in 1947, exhumation work lasted for more than a decade.[185]

Steven Spielberg's famous film Schindler's List focused attention on people like Oscar Schindler and his wife Emilie Schindler, who - at great risk to themselves and their families - helped Jews escape the Nazi genocide. In those years, millions of Jews died in Nazi death camps like Auschwitz, but Oscar Schindler's Jews miraculously survived. Schindler spent millions to protect and save his Jews, everything he possessed. He died penniless.

At the same time, the Nazis cannot be placed in a special category outside history, outside the human condition—a sui generis episode beyond comparison. They must be demythologized and studied closely, because the National Socialist German Workers’ Party and its leader emerged out of a particular context, in a particular time, with a particular set of ideas that won greater and greater purchase the more they were propagated. Moreover, this band of extremist reactionaries were incrementalists. As Whitman emphasizes, “it is simply not the case that the drafters of the Nuremburg Laws were already aiming at the annihilation of the Jews in 1935.” At that point, the Nazis wanted to exile and marginalize the Jewish minority, turning them into second-class citizens.

While the German invasion of the Soviet Union in 1941 was initially successful, the Soviet resurgence and entry of the US into the war meant the Wehrmacht (German armed forces) lost the initiative on the Eastern Front in 1943 and by late 1944 had been pushed back to the pre-1939 border. Large-scale aerial bombing of Germany escalated in 1944 and the Axis powers were driven back in Eastern and Southern Europe. After the Allied invasion of France, Germany was conquered by the Soviet Union from the east and the other Allies from the west, and capitulated in May 1945. Hitler's refusal to admit defeat led to massive destruction of German infrastructure and additional war-related deaths in the closing months of the war. The victorious Allies initiated a policy of denazification and put many of the surviving Nazi leadership on trial for war crimes at the Nuremberg trials.
The following summer, on June 5, 1934, Nazi lawyers, jurists, and medical doctors gathered under the auspices of Justice Minister Franz Gürtner to discuss how to codify the Prussian Memorandum. The very first item discussed was U.S. law: “Almost all the American states have race legislation,” Gürtner averred, before detailing a myriad of examples, including the many states that criminalized mixed marriages. Roland Freisler, the murderous Nazi judge, stated at the meeting that U.S. jurisprudence would “suit us perfectly.” All the participants displayed either an eager interest in, or an avowed knowledge of, U.S. law. This went beyond specific legislation. The Nazis looked to an innovative legal culture that found ways to relegate Native Americans, African Americans, immigrants, Chinese, Japanese, Filipinos, and others to second- and third-class status; the many devious pathways around the constitutional guarantees of equal protection; the deliberate textual ambiguity on the definition of race itself; the draconian penalties for sexually consorting with a lesser race, or even meeting publicly. The United States in the 1930s was the apogee of a racist state.
With its sections separated by barbed-wire fences, Auschwitz II had the largest prisoner population of any of the three main camps. In January 1942, the first chamber using lethal Zyklon B gas was built on the camp. This building was judged inadequate for killing on the scale the Nazis wanted, and four further chambers were built. These were used for systematic genocide right up until November 1944, two months before the camp was liberated.
In 1942, after the death of Armaments Minister Fritz Todt, Hitler appointed Albert Speer as his replacement.[274] 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.[275] 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.[276] Speer improved production by centralising planning and control, reducing production of consumer goods, and using forced labour and slavery.[277][278] 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.[279] 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.[280] 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.[281]

Stalin: Concerning the International Situation (September 1924), in Works, Volume 6, 1953; p. 294.) This later led Otto Wille Kuusinen to conclude that "The aims of the fascists and the social-fascists are the same." (Report To the 10th Plenum of ECCI, in International Press Correspondence, Volume 9, no.40, (20 August 1929), p. 848.)
While civilian efforts had an impact on public opinion, the army was the only organisation with the capacity to overthrow the government.[443][444] A major plot by men in the upper echelons of the military originated in 1938. They believed Britain would go to war over Hitler's planned invasion of Czechoslovakia, and Germany would lose. The plan was to overthrow Hitler or possibly assassinate him. Participants included Generaloberst Ludwig Beck, Generaloberst Walther von Brauchitsch, Generaloberst Franz Halder, Admiral Wilhelm Canaris, and Generalleutnant Erwin von Witzleben, who joined a conspiracy headed by Oberstleutnant Hans Oster and Major Helmuth Groscurth of the Abwehr. The planned coup was cancelled after the signing of the Munich Agreement in September 1938.[445] Many of the same people were involved in a coup planned for 1940, but again the participants changed their minds and backed down, partly because of the popularity of the regime after the early victories in the war.[446][447] Attempts to assassinate Hitler resumed in earnest in 1943, with Henning von Tresckow joining Oster's group and attempting to blow up Hitler's plane in 1943. Several more attempts followed before the failed 20 July 1944 plot, which was at least partly motivated by the increasing prospect of a German defeat in the war.[448][449] The plot, part of Operation Valkyrie, involved Claus von Stauffenberg planting a bomb in the conference room at Wolf's Lair at Rastenburg. Hitler, who narrowly survived, later ordered savage reprisals resulting in the execution of more than 4,900 people.[450]

Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35.[5] 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.[6][7][8] 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[9] and peaked at 715,000 in January 1945.[10]
