The death camp and slave-labour camp were interrelated. Newly arrived prisoners at the death camp were divided in a process known as Selektion. The young and the able-bodied were sent to work. Young children and their mothers and the old and infirm were sent directly to the gas chambers. Thousands of prisoners were also selected by the camp doctor, Josef Mengele, for medical experiments. Auschwitz doctors tested methods of sterilization on the prisoners, using massive doses of radiation, uterine injections, and other barbaric procedures. Experiments involving the killing of twins, upon whom autopsies were performed, were meant to provide information that would supposedly lead to the rapid expansion of the “Aryan race.”
From March 1944, Bergen-Belsen gradually became a concentration camp. The Germans initially began transferring, from other camps, prisoners they classified as ‘unfit to work’. As more transports arrived from Flossenbürg, Gross-Rosen, Ravensbrück, Neuengamme, Mauthausen, and Buchenwald concentration camps, the prisoners were housed in the former ‘prisoners’ camp’. German convicts, transferred from Dora, served as ‘block elders’ and Kapos. They treated other inmates brutally.
With Hitler's approval, Himmler intended that the new society of the Nazi regime should destigmatise illegitimate births, particularly of children fathered by members of the SS, who were vetted for racial purity.[385] His hope was that each SS family would have between four and six children.[385] The Lebensborn (Fountain of Life) association, founded by Himmler in 1935, created a series of maternity homes to accommodate single mothers during their pregnancies.[386] Both parents were examined for racial suitability before acceptance.[386] The resulting children were often adopted into SS families.[386] The homes were also made available to the wives of SS and NSDAP members, who quickly filled over half the available spots.[387]

“It's utterly impossible for me to build my life on a foundation of chaos, suffering and death. I see the world being slowly transformed into a wilderness; I hear the approaching thunder that, one day, will destroy us too. I feel the suffering of millions. And yet, when I look up at the sky, I somehow feel that everything will change for the better, that this cruelty too shall end, that peace and tranquility will return once more.”
One of the first people I encountered was Mengele. He told us to undress and stand in line and he went through the ranks deciding who was strong and healthy and fit for work, and who was only fit for the gas chamber. After inspecting me, he put his thumb up high, so they gave me the striped uniform and sent me to get a number tattooed on to my arm. I don’t remember the number. It’s there still, but I never look at it because it brings back too many painful memories.
Nazism had peculiarly German roots. It can be partly traced to the Prussian tradition as developed under Frederick William I (1688–1740), Frederick the Great (1712–68), and Otto von Bismarck (1815–98), which regarded the militant spirit and the discipline of the Prussian army as the model for all individual and civic life. To it was added the tradition of political romanticism, with its sharp hostility to rationalism and to the principles underlying the French Revolution, its emphasis on instinct and the past, and its proclamation of the rights of Friedrich Nietzsche’s exceptional individual (the Übermensch [“Superman”]) over all universal law and rules. These two traditions were later reinforced by the 19th-century adoration of science and of the laws of nature, which seemed to operate independently of all concepts of good and evil. Further reinforcements came from such 19th-century intellectual figures as the comte de Gobineau (1816–82), Richard Wagner (1813–83), and Houston Stewart Chamberlain (1855–1927), all of whom greatly influenced early National Socialism with their claims of the racial and cultural superiority of the “Nordic” (Germanic) peoples over all other Europeans and all other races.
The last days of Auschwitz, which was opened by the Nazis in Oswiecim, Poland, in 1940, were marked by chaos, cowardice and an attempt to destroy what was once one of Nazi Germany’s most efficient tools in the quest to eradicate European Jews. By late 1944, as the Allied forces of World War II wrested much of occupied Europe out of Nazi hands, it had become clear that the Nazi military—once a mighty force that had invaded and occupied most of Europe after Hitler’s rise to power in 1933—was headed toward a spectacular defeat.
On our arrival at Auschwitz they chased us off the cattle wagon, which stopped right in front of the gate with the sign Arbeit Macht Frei (Work Makes You Free). I thought I was entering a labour camp, but little did I know. They asked me my profession, and I said painter as I’d picked up the advice en route to say something practical and useful. If I’d said I’d just finished high school they’d have sent me straight to the gas chambers.
Otto Frank gave the diary to the historian Annie Romein-Verschoor, who tried unsuccessfully to have it published. She then gave it to her husband Jan Romein, who wrote an article about it, titled "Kinderstem" ("A Child's Voice"), which was published in the newspaper Het Parool on 3 April 1946. He wrote that the diary "stammered out in a child's voice, embodies all the hideousness of fascism, more so than all the evidence at Nuremberg put together."[69] His article attracted attention from publishers, and the diary was published in the Netherlands as Het Achterhuis (The Annex) in 1947,[70] followed by five more printings by 1950.[71]
Officially, the Third Reich lasted only 12 years. The first Instrument of Surrender was signed by representatives of Nazi Germany at Reims, France on 7 May 1945. The war in Europe had come to an end. The defeat of Germany in World War II marked the end of the Nazi Germany era.[88] The party was formally abolished on 10 October 1945 by the Allied Control Council and denazification began, along with trials of major war criminals before the International Military Tribunal (IMT) in Nuremberg.[89] Part of the Potsdam Agreement called for the destruction of the Nationalist Socialist Party alongside the requirement for the reconstruction of the German political life.[90] In addition, the Control Council Law no. 2 Providing for the Termination and Liquidation of the Nazi Organization specified the abolition of 52 other Nazi affiliated and supervised organisations and prohibited their activities.[91] The denazification was carried out in Germany and continued until the onset of the Cold War.[92][93]
Auschwitz Birkenau was het grootste concentratie- en vernietigingskamp in het Derde Rijk. De versterkte muren, prikkeldraad, perrons, galg, gaskamers en crematieovens laten de omstandigheden zien waarin de genocide door de nazi’s plaats vond. Volgens historisch onderzoek werden er in dit kamp 1,5 miljoen mensen, systematisch uitgehongerd, gemarteld en vermoord. Hiervan waren er meer dan een miljoen Joods en tienduizenden Pools. Auschwitz diende ook als een kamp voor de raciale moord op duizenden Roma en Sinti. De plaats staat symbool voor de wreedheid die de mens zijn medemens in de 20e eeuw aandeed. Het kamp is een belangrijke plaats ter herinnering aan de Holocaust.

In early 1942, at the Wannsee Conference near Berlin, the Nazi Party decided on the last phase of what it called the “Final Solution” of the “Jewish problem” and spelled out plans for the systematic murder of all European Jews. In 1942 and 1943, Jews in the western occupied countries including France and Belgium were deported by the thousands to the death camps mushrooming across Europe. In Poland, huge death camps such as Auschwitz began operating with ruthless efficiency. The murder of Jews in German-occupied lands stopped only in last months of the war, as the German armies were retreating toward Berlin. By the time Hitler committed suicide in April 1945, some 6 million Jews had died.
During the Röhm Purge of 30 June to 2 July 1934 (also known as the "Night of the Long Knives"), Hitler disempowered the SA's leadership—most of whom belonged to the Strasserist (national revolutionary) faction within the NSDAP—and ordered them killed. He accused them of having conspired to stage a coup d'état, but it is believed that this was only a pretence to justify the suppression of any intraparty opposition. The purge was executed by the SS, assisted by the Gestapo and Reichswehr units. Aside from Strasserist Nazis, they also murdered anti-Nazi conservative figures like former chancellor Kurt von Schleicher.[84] After this, the SA continued to exist but lost much of its importance, while the role of the SS grew significantly. Formerly only a sub-organisation of the SA, it was made into a separate organisation of the NSDAP in July 1934.[85]
German business leaders disliked Nazi ideology but came to support Hitler, because they saw the Nazis as a useful ally to promote their interests.[54] Business groups made significant financial contributions to the Nazi Party both before and after the Nazi seizure of power, in the hope that a Nazi dictatorship would eliminate the organized labour movement and the left-wing parties.[55] Hitler actively sought to gain the support of business leaders by arguing that private enterprise is incompatible with democracy.[56]
Notions of white supremacy and Aryan racial superiority were combined in the 19th century, with white supremacists maintaining the belief that certain groups of white people were members of an Aryan "master race" that is superior to other races and particularly superior to the Semitic race, which they associated with "cultural sterility".[80] Arthur de Gobineau, a French racial theorist and aristocrat, blamed the fall of the ancien régime in France on racial degeneracy caused by racial intermixing, which he argued had destroyed the purity of the Aryan race, a term which he only reserved for Germanic people.[81][82] Gobineau's theories, which attracted a strong following in Germany,[81] emphasized the existence of an irreconcilable polarity between Aryan (Germanic) and Jewish cultures.[80]
We tried to get out – we’d seen the signs of what was to come, not that we could really have known the full extent of what would happen. My uncle had worked in Palestine in 1917 but had been forced to return to Poland when he got sick. We tried to use the contacts he still had there to escape, but the British (who were in control of it) wouldn’t give us permission to go there. In my mind they carry a lot of the blame for the deaths of many of the Jews – especially the Polish Jews – who perished.

One of the most significant ideological influences on the Nazis was the German nationalist Johann Gottlieb Fichte, whose works had served as an inspiration to Hitler and other Nazi Party members, including Dietrich Eckart and Arnold Fanck.[61] In Speeches to the German Nation (1808), written amid Napoleonic France's occupation of Berlin, Fichte called for a German national revolution against the French occupiers, making passionate public speeches, arming his students for battle against the French and stressing the need for action by the German nation so it could free itself.[62] Fichte's nationalism was populist and opposed to traditional elites, spoke of the need for a "People's War" (Volkskrieg) and put forth concepts similar to those which the Nazis adopted.[62] Fichte promoted German exceptionalism and stressed the need for the German nation to purify itself (including purging the German language of French words, a policy that the Nazis undertook upon their rise to power).[62]
Although the factory had been expected to begin production in 1943, shortages of labor and raw materials meant start-up had to be postponed repeatedly.[64] The Allies bombed the plant in 1944 on 20 August, 13 September, 18 December, and again on 26 December. On 19 January 1945, the SS ordered that the site be evacuated, sending 9,000 inmates on a death march to another Auschwitz subcamp at Gliwice.[65] The plant had almost been ready to commence production.[66] From Gliwice, prisoners were taken by rail in open freight wagons to Buchenwald and Mauthausen concentration camps. The 800 inmates who had been left behind in the Monowitz hospital were liberated on 27 January 1945 by the 1st Ukrainian Front of the Red Army.[67]

The two largest groups of prisoners in the camps, both numbering in the millions, were the Polish Jews and the Soviet prisoners of war (POWs) held without trial or judicial process. There were also large numbers of Romani people, ethnic Poles, Serbs, political prisoners, homosexuals, people with disabilities, Jehovah's Witnesses, Catholic clergy, Eastern European intellectuals and others (including common criminals, as the Nazis declared). In addition, a small number of Western Allied aviators were sent to concentration camps as punishment for spying.[28] Western Allied POWs who were Jews, or who were suspected of being Jews by the Nazis, were usually sent to ordinary POW camps; however, a small number of them were sent to concentration camps because of antisemitic policies.[29]
