Carl Clauberg was put to trial in the Soviet Union and sentenced to 25 years. 7 years later, he was pardonned under the returnee arrangement between Bonn and Moscow and went back to West Germany. Upon returning he held a press conference and boasted of his scientific work at Auschwitz. After survivor groups protested, Clauberg was finally arrested in 1955 but died in August 1957, shortly before his trial should have started.
Once Hitler gained control of the government, he directed Nazi Germany’s foreign policy toward undoing the Treaty of Versailles and restoring Germany’s standing in the world. He railed against the treaty’s redrawn map of Europe and argued it denied Germany, Europe’s most populous state, “living space” for its growing population. Although the Treaty of Versailles was explicitly based on the principle of the self-determination of peoples, he pointed out that it had separated Germans from Germans by creating such new postwar states as Austria and Czechoslovakia, where many Germans lived.
Army photographers and cameramen, along with leading war correspondents, recorded the aftermath of Bergen-Belsen's liberation. This photograph was taken by Sergeant Harry Oakes of the Army Film and Photographic Unit. It shows prisoners sitting by a wire fence which divided two sections of the camp. They are eating their first meal after the liberation of the camp.

Beginning in April 1933, scores of measures defining the status of Jews and their rights were instituted.[49] These measures culminated in the establishment of the Nuremberg Laws of 1935, which stripped them of their basic rights.[50] The Nazis would take from the Jews their wealth, their right to intermarry with non-Jews, and their right to occupy many fields of labour (such as law, medicine, or education). Eventually the Nazis declared the Jews as undesirable to remain among German citizens and society.[51]
My whole world was turned upside down by the brutality of it. We had not in any way understood what had been going on, only later recognising all the sources and streams that led to the Holocaust. In my small Hungarian village, information had been very restricted. We didn’t know about anything, like the Wannsee conference (where the Final Solution was planned), and neither could we have imagined it. We were told by the authorities that we were being resettled, which is why I took my sewing machine with me. I took my sewing machine!
In most of the concentration camps, the Nazi SS either installed or had plans to install gas chambers to assist in their daily business of killing prisoners who were too weak or sick to work. Gas chambers were also to kill small targeted groups of individuals whom the Nazis wanted to eliminate (Polish resistance fighters, Soviet POWs, etc.). This was the purpose of the installation of gas chambers at Mauthausen, Sachsenhausen, Stutthof, Auschwitz I, Ravensbrück, Lublin/Majdanek, etc.

The Zyklon B was delivered by ambulance to the crematoria by a special SS bureau known as the Hygienic Institute.[104] The actual delivery of the gas to the victims was always handled by the SS, on the order of the supervising SS doctor.[174][175] After the doors were shut, SS men dumped in the Zyklon B pellets through vents in the roof or holes in the side of the chamber. The victims were dead within 20 minutes.[174] Despite the thick concrete walls, screaming and moaning from within could be heard outside. In one failed attempt to muffle the noise, two motorcycle engines were revved up to full throttle nearby, but the sound of yelling could still be heard over the engines.[176]

Le Porz’s remark was prophetic. The true extent of Nazi barbarity became known to the world in part through the documentary films made by Allied forces after the liberation of other German camps. There have been many atrocities committed before and since, yet to this day, thanks to those images, the Nazi concentration camp stands as the ultimate symbol of evil. The very names of the camps—Dachau, Bergen-Belsen, Buchenwald, Auschwitz—have the sound of a malevolent incantation. They have ceased to be ordinary place names—Buchenwald, after all, means simply “beech wood”—and become portals to a terrible other dimension.
After the outbreak of war, people from across Europe were deported to Mauthausen, which gradually developed into a system of several interconnected camps. During this phase, Mauthausen and Gusen were the concentration camps with the harshest imprisonment conditions and the highest mortality. Prisoners at the bottom of the camp hierarchy had barely any chance of surviving for long. Those who were ill or ‘useless’ to the SS were in constant danger of their lives. In 1941 the SS started to construct a gas chamber and other installations at Mauthausen for the systematic murder of large groups of people.

On July 14, 1933, his government declared the Nazi Party to be the only political party in Germany. On the death of Hindenburg in 1934 Hitler took the titles of Führer (“Leader”), chancellor, and commander in chief of the army, and he remained leader of the Nazi Party as well. Nazi Party membership became mandatory for all higher civil servants and bureaucrats, and the gauleiters became powerful figures in the state governments. Hitler crushed the Nazi Party’s left, or socialist-oriented, wing in 1934, executing Ernst Röhm and other rebellious SA leaders on what would become known as the “Night of the Long Knives.” Thereafter, Hitler’s word was the supreme and undisputed command in the party. The party came to control virtually all political, social, and cultural activities in Germany. Its vast and complex hierarchy was structured like a pyramid, with party-controlled mass organizations for youth, women, workers, and other groups at the bottom, party members and officials in the middle, and Hitler and his closest associates at the top wielding undisputed authority.
Los recintos, las alambradas, las torretas de vigilancia, las casamatas, las horcas, las cámaras de gas y los hornos crematorios de este campo de concentración y exterminio, que fue el más vasto de los creados por el Tercer Reich, dan fe de las condiciones en que se perpetró el genocidio nazi. Según los trabajos de investigación histórica, entre 1.100.000 y 1.500.000 prisioneros –en gran parte judíos– fueron sistemáticamente privados de alimentación, torturados y asesinados en este campo, símbolo de la crueldad ejercida por el hombre contra sus semejantes en el siglo XX.
A concentration camp to house Soviet prisoners of war and Poles had been established at Majdanek, close to the Polish city of Lublin, during 1941. In the spring of 1942 gas chambers and crematoria were added, turning Majdanek into an extermination camp that would murder 78,000 people. Auschwitz-Birkenau, the most infamous of the Nazi death camps, was a massive concentration, forced labour and extermination camp at the centre of a network of more than 40 satellite camps. Upwards of 80 per cent of those Jews transported to Auschwitz-Birkenau were selected for immediate death.
In the course of the war, the camp was staffed by 7,000 members of the German Schutzstaffel (SS), approximately 12 percent of whom were later convicted of war crimes. Several, including camp commandant Rudolf Höss, were executed. The Allies did not act on early reports of atrocities at the camp, and their failure to bomb the camp or its railways remains controversial. At least 802 prisoners tried to escape from Auschwitz, 144 successfully, and on 7 October 1944 two Sonderkommando units, consisting of prisoners assigned to staff the gas chambers, launched a brief, unsuccessful uprising.
Nazi flags: The Nazi Party used a right-facing swastika as their symbol and the red and black colours were said to represent Blut und Boden ("blood and soil"). Another definition of the flag describes the colours as representing the ideology of National Socialism, the swastika representing the Aryan race and the Aryan nationalist agenda of the movement; white representing Aryan racial purity; and red representing the socialist agenda of the movement. Black, white and red were in fact the colours of the old North German Confederation flag (invented by Otto von Bismarck, based on the Prussian colours black and white and the red used by northern German states). In 1871, with the foundation of the German Reich the flag of the North German Confederation became the German Reichsflagge ("Reich flag"). Black, white and red became the colours of the nationalists through the following history (for example World War I and the Weimar Republic).
Frank herself sensed the limits of the adults around her, writing critically of her own mother’s and Peter’s mother’s apparently trivial preoccupations—and in fact these women’s prewar lives as housewives were a chief driver for Frank’s ambitions. “I can’t imagine that I would have to lead the same sort of life as Mummy and Mrs. v.P. [van Pels] and all the women who do their work and are then forgotten,” she wrote as she planned her future career. “I must have something besides a husband and children, something that I can devote myself to!” In the published diary, this passage is immediately followed by the famous words, “I want to go on living even after my death!”
These sights, like the truck full of bodies, are not beyond belief—we know that they were true—but they are, in some sense, beyond imagination. It is very hard, maybe impossible, to imagine being one of those men, still less one of those infants. And such sights raise the question of why, exactly, we read about the camps. If it is merely to revel in the grotesque, then learning about this evil is itself a species of evil, a further exploitation of the dead. If it is to exercise sympathy or pay a debt to memory, then it quickly becomes clear that the exercise is hopeless, the debt overwhelming: there is no way to feel as much, remember as much, imagine as much as the dead justly demand. What remains as a justification is the future: the determination never again to allow something like the Nazi camps to exist.

"Like the adults, the kids were only a mere bag of bones, without muscles or fat, and the thin skin like pergament scrubbed through and through beyond the hard bones of the skeleton and ignited itself to ulcerated wounds. Abscesses covered the underfed body from the top to the bottom and thus deprived it from the last rest of energy. The mouth was deeply gnawed by noma-abscesses, hollowed out the jaw and perforated the cheeks like cancer". Many decaying bodies were full of water because of the burning hunger, they swelled to shapeless bulks which could not move anymore. Diarrhoea, lasting for weeks, dissolved their irresistant bodies until nothing remained ....." 
The crematoria consisted of a dressing room, gas chamber, and furnace room. In crematoria II and III, the dressing room and gas chamber were underground; in IV and V, they were on the ground floor. The dressing room had numbered hooks on the wall to hang clothes. In crematorium II, there was also a dissection room (Sezierraum).[172] SS officers told the victims they were to take a shower and undergo delousing. The victims undressed in the dressing room and walked into the gas chamber, which was disguised as a shower facility; signs in German said "To the baths" and "To disinfection". Some inmates were even given soap and a towel.[173]
By then, Auschwitz was serving as both a slave labor facility and a death camp. As the Germans brought more and more Jews from all over Europe to the sprawling complex, SS doctors selected the fittest for work. Other prisoners were sent directly to Birkenau’s gas chambers for what was euphemistically known as a special action. “Was present for first time at a special action at 3 a.m. By comparison Dante’s Inferno seems almost a comedy,” SS doctor Johann Paul Kremer wrote in his diary on September 2, 1942. Camp records show the transport he observed contained 957 Jews from France; only 12 men and 27 women were selected for work.

The Kurds, who share ethnic and cultural similarities with Iranians and are mostly Muslim by religion (largely Sunni but with many minorities), have long struggled for self-determination. After World War I, their lands were divided up between Iraq, Iran, Syria, and Turkey. In Iran, though there have been small separatist movements, Kurds are mostly subjected to the same repressive treatment as everyone else (though they also face Persian and Shi’ite chauvinism, and a number of Kurdish political prisoners were recently executed). The situation is worse in Iraq, Syria, and Turkey, where the Kurds are a minority people subjected to ethnically targeted violations of human rights.  

The Protocols of the Elders of Zion (1912) is an antisemitic forgery created by the secret service of the Russian Empire, the Okhrana. Many antisemites believed it was real and thus it became widely popular after World War I.[92] The Protocols claimed that there was a secret international Jewish conspiracy to take over the world.[93] Hitler had been introduced to The Protocols by Alfred Rosenberg and from 1920 onwards he focused his attacks by claiming that Judaism and Marxism were directly connected, that Jews and Bolsheviks were one and the same and that Marxism was a Jewish ideology-this became known as "Jewish Bolshevism".[94] Hitler believed that The Protocols were authentic.[95]

The Reichstag fire on 27 February 1933 gave Hitler a pretext for suppressing his political opponents. The following day he persuaded the Reich's President Paul von Hindenburg to issue the Reichstag Fire Decree, which suspended most civil liberties. The NSDAP won the parliamentary election on 5 March 1933 with 43.9 percent of votes, but failed to win an absolute majority. After the election, hundreds of thousands of new members joined the party for opportunistic reasons, most of them civil servants and white-collar workers. They were nicknamed the "casualties of March" (German: Märzgefallenen) or "March violets" (German: Märzveilchen).[78] To protect the party from too many non-ideological turncoats who were viewed by the so-called "old fighters" (alte Kämpfer) with some mistrust,[79] the party issued a freeze on admissions that remained in force from May 1933 to 1937.[80]
The women's concentration camp (Frauenkonzentrationslager or FKL) was established in August 1942, in 15 brick and 15 wooden barracks in sector BIa (Bauabschnitt Ia) in Auschwitz II, when 13,000 women were transferred from Auschwitz I. The camp was later extended into sector BIb, and by October 1943 it held 32,066 women. Conditions in the camp were so poor that, in October 1942, when a group of male prisoners arrived to set up an infirmary, their first task, according to researchers from the Auschwitz museum, was to distinguish the corpses from the women who were still alive.[123] Gisella Perl, a Romanian-Jewish gynecologist and inmate of the women's camp, wrote in 1948:

The third camp, Auschwitz III, also called Monowitz, was opened in October 1942. It was predominantly used as a base for imprisoned labourers working for the German chemical company IG Farben. According to the Auschwitz-Birkenau memorial museum, an estimated 10,000 labourers are thought to have died there. Once they were judged incapable of work, most were killed with a phenol injection to the heart.

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.

"The Reception of Luther's Writings on the Jews from the Reformation to the End of the 19th Century", Lutheran Quarterly, n.s. 1 (Spring 1987) 1:72–97. Wallmann writes: "The assertion that Luther's expressions of anti-Jewish sentiment have been of major and persistent influence in the centuries after the Reformation, and that there exists a continuity between Protestant anti-Judaism and modern racially oriented anti-Semitism, is at present wide-spread in the literature; since the Second World War it has understandably become the prevailing opinion." * Michael, Robert. Holy Hatred: Christianity, Antisemitism, and the Holocaust. New York: Palgrave Macmillan, 2006; see chapter 4 "The Germanies from Luther to Hitler", pp. 105–151. * Hillerbrand, Hans J. "Martin Luther," Encyclopædia Britannica, 2007. Hillerbrand writes: "[H]is strident pronouncements against the Jews, especially toward the end of his life, have raised the question of whether Luther significantly encouraged the development of German anti-Semitism. Although many scholars have taken this view, this perspective puts far too much emphasis on Luther and not enough on the larger peculiarities of German history."
In April 1940, Rudolph Höss, who become the first commandant, identified the Silesian town of Oswiecim as a possible site for a concentration camp. The function of the camp was initially to intimidate Poles and prevent resistance to German rule. It was also perceived as a cornerstone of the policy to re-colonize Upper Silesia, which had once been a German region, with 'pure Aryans'. On April 27th, Himmler ordered construction of the camp.
