Nine out of 10 victims in Auschwitz-Birkenau were Jews. The remaining victims were mainly Poles, gypsies, and Soviet POW’s. Majdanek began its gassings in October 1942. The camp functioned in the same way as Auschwitz-Birkenau, and also included a concentration- and work camp. In the autumn of 1943 the camp was closed after claiming between 60,000 and 80,000 Jewish victims.
Of the seven people who hid in the secret annex, only Otto Frank survived. Upon returning to Amsterdam on June 3, he discovered that his employees had faithfully kept his business running, awaiting his return. He stayed with Miep Gies and her husband and immediately began searching for his daughters—in mid-July, he learned of their deaths at Bergen-Belsen.
The twin pairs of gas chambers were numbered II and III, and IV and V. The first opened on March 31, 1943, the last on April 4, 1943. The total area of the gas chambers was 2,255 square meters; the capacity of these crematoria was 4,420 people. Those selected to die were undressed in the undressing room and then pushed into the gas chambers. It took about 20 minutes for all the people to death. In II and III, the killings took place in underground rooms, and the corpses were carried to the five ovens by an electrically operated lift. Before cremation gold teeth and any other valuables, such as rings, were removed from the corpses. In IV and V the gas chambers and ovens were on the same level, but the ovens were so poorly built and the usage was so great that they repeatedly malfunctioned and had to be abandoned. The corpses were finally burned outside, in the open, as in 1943. Jewish sonderkommandos worked the crematoria under SS supervision.

The courtyard between blocks 10 and 11, known as the "death wall" served as an execution area for Poles not in Auschwitz who had been sentenced to death by a criminal court—presided over by German judges—including for petty crimes such as stealing food.[139] Several rooms in block 11 were deemed the Polizei-Ersatz-Gefängnis Myslowitz in Auschwitz ("Alternative jail of the police station at Mysłowice").[140] There were also Sonderbehandlung cases ("special treatment") for Poles and others regarded as dangerous to the Third Reich.[141] Members of the camp resistance were shot there, as were 200 of the Sonderkommandos who took part in the Sonderkommando revolt in October 1944.[142] Thousands of Poles were executed at the death wall; Höss wrote that "execution orders arrived in an unbroken stream".[143]
In Autumn 1943, the camp administration was reorganized following a corruption scandal. By the end of 1943, the prisoner population of Auschwitz main camp, Birkenau, Monowitz and other subcamps was over 80,000: 18,437 in the main camp, 49,114 in Birkenau, and 13,288 at Monowitz where I G Farben had its synthetic rubber plant. Up to 50,000 prisoners were scattered around 51 subcamps such as Rajsko, an experimental agricultural station, and Gleiwitz, a coal mine (see The List of the Camps for a complete list of those subcamps).
From its rise to power in 1933, the Nazi regime built a series of incarceration sites to imprison and eliminate so-called "enemies of the state." Most prisoners in the early concentration camps were German Communists, Socialists, Social Democrats, Roma (Gypsies), Jehovah's Witnesses, homosexuals, and persons accused of "asocial" or socially deviant behavior. Some of these facilities were called “concentration camps” because those imprisoned there were physically “concentrated” in one location.
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!”
To write the history of such an institution, as Nikolaus Wachsmann sets out to do in another new book, “KL: A History of the Nazi Concentration Camps” (Farrar, Straus & Giroux), might seem impossible, like writing the history of Hell. And, certainly, both his book and Helm’s are full of the kind of details that ordinarily appear only in Dantesque visions. Helm devotes a chapter to Ravensbrück’s Kinderzimmer, or “children’s room,” where inmates who came to the camp pregnant were forced to abandon their babies; the newborns were left to die of starvation or be eaten alive by rats. Wachsmann quotes a prisoner at Dachau who saw a transport of men afflicted by dysentery arrive at the camp: “We saw dozens . . . with excrement running out of their trousers. Their hands, too, were full of excrement and they screamed and rubbed their dirty hands across their faces.”
In the 1920s, political opponents of the NSDAP in the German labour movement seized on this and – using the earlier abbreviated term "Sozi" for Sozialist (English: Socialist) as an example[8] – shortened the first part of the NSDAP's name, Nationalsozialistische, to the dismissive "Nazi", in order to associate them with the derogatory use of the term mentioned above.[9][7][10][11][12][13]
After Germany's annexation of Austria in March 1938, the Nazis arrested German and Austrian Jews and imprisoned them in the Dachau, Buchenwald, and Sachsenhausen concentration camps, all located in Germany. Following the violent Kristallnacht ("Night of Broken Glass") pogroms in November 1938, the Nazis conducted mass arrests of adult male Jews and incarcerated them in camps for brief periods.
On the night of 27 February 1933, the Reichstag building was set afire. Marinus van der Lubbe, a Dutch communist, was found guilty of starting the blaze. Hitler proclaimed that the arson marked the start of a communist uprising. The Reichstag Fire Decree, imposed on 28 February 1933, rescinded most civil liberties, including rights of assembly and freedom of the press. The decree also allowed the police to detain people indefinitely without charges. The legislation was accompanied by a propaganda campaign that led to public support for the measure. Violent suppression of communists by the SA was undertaken nationwide and 4,000 members of the Communist Party of Germany were arrested.[16]
During his youth in Austria, Hitler was politically influenced by Austrian Pan-Germanist proponent Georg Ritter von Schönerer, who advocated radical German nationalism, antisemitism, anti-Catholicism, anti-Slavic sentiment and anti-Habsburg views.[77] From von Schönerer and his followers, Hitler adopted for the Nazi movement the Heil greeting, the Führer title and the model of absolute party leadership.[77] Hitler was also impressed by the populist antisemitism and the anti-liberal bourgeois agitation of Karl Lueger, who as the mayor of Vienna during Hitler's time in the city used a rabble-rousing style of oratory that appealed to the wider masses.[78] Unlike von Schönerer, Lueger was not a German nationalist and instead was a pro-Catholic Habsburg supporter and only used German nationalist notions occasionally for his own agenda.[78] Although Hitler praised both Lueger and Schönerer, he criticized the former for not applying a racial doctrine against the Jews and Slavs.[79]
Auschwitz, Polish Oświęcim, also called Auschwitz-Birkenau, Nazi Germany’s largest concentration camp and extermination camp. Located near the industrial town of Oświęcim in southern Poland (in a portion of the country that was annexed by Germany at the beginning of World War II), Auschwitz was actually three camps in one: a prison camp, an extermination camp, and a slave-labour camp. As the most lethal of the Nazi extermination camps, Auschwitz has become the emblematic site of the “final solution,” a virtual synonym for the Holocaust. Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews. Also among the dead were some 19,000 Roma who were held at the camp until the Nazis gassed them on July 31, 1944—the only other victim group gassed in family units alongside the Jews. The Poles constituted the second largest victim group at Auschwitz, where some 83,000 were killed or died.

Women were a cornerstone of Nazi social policy. The Nazis opposed the feminist movement, claiming that it was the creation of Jewish intellectuals, instead advocating a patriarchal society in which the German woman would recognise that her "world is her husband, her family, her children, and her home".[264] Feminist groups were shut down or incorporated into the National Socialist Women's League, which coordinated groups throughout the country to promote motherhood and household activities. Courses were offered on childrearing, sewing, and cooking. Prominent feminists, including Anita Augspurg, Lida Gustava Heymann, and Helene Stöcker, felt forced to live in exile.[367] The League published the NS-Frauen-Warte, the only NSDAP-approved women's magazine in Nazi Germany;[368] despite some propaganda aspects, it was predominantly an ordinary woman's magazine.[369]
During the first half of July, Anne and her family hid in an apartment that would eventually hide four Dutch Jews as well—Hermann, Auguste, and Peter van Pels, and Fritz Pfeffer. For two years, they lived in a secret attic apartment behind the office of the family-owned business at 263 Prinsengracht Street, which Anne referred to in her diary as the Secret Annex. Otto Frank's friends and colleagues, Johannes Kleiman, Victor Kugler, Jan Gies, and Miep Gies, had helped to prepare the hiding place and smuggled food and clothing to the Franks at great risk to their own lives.

Jewish deportees arriving at Auschwitz-Birkenau immediately underwent selection. The SS staff chose some of the able-bodied for forced labor and sent the rest directly to the gas chambers, which were disguised as shower installations to mislead the victims. The belongings of all deportees were confiscated and sorted in the "Kanada" (Canada) warehouse for shipment back to Germany. Canada symbolized wealth to the prisoners.
After Germany's annexation of Austria in March 1938, the Nazis arrested German and Austrian Jews and imprisoned them in the Dachau, Buchenwald, and Sachsenhausen concentration camps, all located in Germany. Following the violent Kristallnacht ("Night of Broken Glass") pogroms in November 1938, the Nazis conducted mass arrests of adult male Jews and incarcerated them in camps for brief periods.
Soon afterwards, the gas chambers and crematoria were destroyed on Himmler's orders, since the regime wanted to hide the traces of its murdering machine ahead of the advancing Red Army. As Soviet troops came near to the camp in January 1945, it was hurriedly evacuated and 58 000 prisoners were driven out on a death march, during which most were killed. On the 27th of January 1945, the Red Army entered the camp (link in Czech). They found 7 650 exhausted and starving prisoners and a number of pieces of evidence of crimes that the Nazis had not had time to destroy. In the camp stores they found almost eight tonnes of human hair and over a million men's suits and women's dresses.
They did not greet us, nor did they smile; they seemed oppressed not only by compassion but by a confused restraint, which sealed their lips and bound their eyes to the funereal scene. It was that shame we knew so well, the shame that drowned us after the selections, and every time we had to watch, or submit to, some outrage: the shame the Germans did not know, that the just man experiences at another man's crime; the feeling of guilt that such a crime should exist, that it should have been introduced irrevocably into the world of things that exist, and that his will for good should have proved too weak or null, and should not have availed in defence.[252]
During June and July 1933, all competing parties were either outlawed or dissolved themselves and subsequently the Law against the founding of new parties of 14 July 1933 legally established the Nazi Party's monopoly. On 1 December 1933, the Law to secure the unity of party and state entered into force, which was the base for a progressive intertwining of party structures and state apparatus.[82] By this law, the SA—actually a party division—was given quasi-governmental authority and their leader was co-opted as an ex officio cabinet member. By virtue of a 30 January 1934 Law concerning the reorganisation of the Reich, the Länder (states) lost their statehood and were demoted to administrative divisions of the Reich's government (Gleichschaltung). Effectively, they lost most of their power to the Gaue that were originally just regional divisions of the party, but took over most competencies of the state administration in their respective sectors.[83]
And it means deploying conservators to preserve an inventory that includes more than a ton of human hair; 110,000 shoes; 3,800 suitcases; 470 prostheses and orthopedic braces; more than 88 pounds of eyeglasses; hundreds of empty canisters of Zyklon B poison pellets; patented metal piping and showerheads for the gas chambers; hundreds of hairbrushes and toothbrushes; 379 striped uniforms; 246 prayer shawls; more than 12,000 pots and pans carried by Jews who believed that they were simply bound for resettlement; and some 750 feet of SS documents — hygiene records, telegrams, architectural blueprints and other evidence of the bureaucracy of genocide — as well as thousands of memoirs by survivors.
[Hitler] compiled a most extensive set of revolutionary goals (calling for radical social and political change); he mobilized a revolutionary following so extensive and powerful that many of his aims were achieved; he established and ran a dictatorial revolutionary state; and he disseminated his ideas abroad through a revolutionary foreign policy and war. In short, he defined and controlled the National Socialist revolution in all its phases.[283]

I now live in Hanover, Germany, which doesn’t feel strange to me to be living in the land of the murderers, because it’s a different country now. At least people listen to my story here. When I travel to the US nobody asks me, so I never say anything. But I have a hunch that as soon as his feet touch the ground in Auschwitz, my nephew’s son will start to ask questions.

However, after the Nazis' "Seizure of Power" in 1933, Röhm and the Brown Shirts were not content for the party to simply carry the reigns of power. Instead, they pressed for a continuation of the "National Socialist revolution" to bring about sweeping social changes, which Hitler, primarily for tactical reasons, was not willing to do at that time. He was instead focused on rebuilding the military and reorienting the economy to provide the rearmament necessary for invasion of the countries to the east of Germany, especially Poland and Russia, to get the Lebensraum ("living space") he believed was necessary to the survival of the Aryan race. For this, he needed the co-operation of not only the military, but also the vital organs of capitalism, the banks and big businesses, which he would be unlikely to get if Germany's social and economic structure was being radically overhauled. Röhm's public proclamation that the SA would not allow the "German Revolution" to be halted or undermined caused Hitler to announce that "The revolution is not a permanent condition." The unwillingness of Röhm and the SA to cease their agitation for a "Second Revolution", and the unwarranted fear of a "Röhm putsch" to accomplish it, were factors behind Hitler's purging of the SA leadership in the Night of the Long Knives in July 1934.[281][282]
Nazism rejected the Marxist concept of class conflict, and it praised both German capitalists and German workers as essential to the Volksgemeinschaft. In the Volksgemeinschaft, social classes would continue to exist, but there would be no class conflict between them.[170] Hitler said that "the capitalists have worked their way to the top through their capacity, and as the basis of this selection, which again only proves their higher race, they have a right to lead."[171] German business leaders co-operated with the Nazis during their rise to power and received substantial benefits from the Nazi state after it was established, including high profits and state-sanctioned monopolies and cartels.[172] Large celebrations and symbolism were used extensively to encourage those engaged in physical labour on behalf of Germany, with leading National Socialists often praising the "honour of labour", which fostered a sense of community (Gemeinschaft) for the German people and promoted solidarity towards the Nazi cause.[173] To win workers away from Marxism, Nazi propaganda sometimes presented its expansionist foreign policy goals as a "class struggle between nations."[171] Bonfires were made of school children's differently coloured caps as symbolic of the unity of different social classes.[174]
Around 7,000 SS personnel were posted to Auschwitz during the war.[84] Of these, 4 percent of SS personnel were officers and 26 percent were non-commissioned officers, while the remainder were rank-and-file members.[85] Camp guards were members of the SS-Totenkopfverbände (Death's Head Units).[86] Approximately three in four SS personnel worked in security. Others worked in the medical or political departments, in the camp headquarters, or in the economic administration, which was responsible for the property of dead prisoners.[85] SS personnel at the camp included 200 women, who worked as guards, nurses, or messengers.[80] About 120 SS personnel were assigned to the gas chambers and lived on site at the crematoria.[87]
Jews, Gypsies (Roma), homosexuals, asocials, criminals, and prisoners of war were gathered, stuffed into cattle cars on trains, and sent to Auschwitz. When the trains stopped at Auschwitz II: Birkenau, the newly arrived were told to leave all their belongings on board and were then forced to disembark from the train and gather upon the railway platform, known as "the ramp."
On 25 November 1947, the Auschwitz trial began in Kraków, when Poland's Supreme National Tribunal brought to court 40 former Auschwitz staff. The trial's defendants included commandant Arthur Liebehenschel, women's camp leader Maria Mandel, and camp leader Hans Aumeier. The trials ended on 22 December 1947, with 23 death sentences, 7 life sentences, and 9 prison sentences ranging from three to fifteen years. Hans Münch, an SS doctor who had several former prisoners testify on his behalf, was the only person to be acquitted.[268]
Forced-Labor Camps and transit camps: Forced labor camps were utilized for pointless and humiliating labor, imposed on prisoners without proper equipment, clothing, nourishment, or rest. Transit camps functioned as temporary holding facilities for Jews awaiting deportation. These camps were usually the last stop before deportations to a killing center. There were 1,830 forced labor and transit camps.

In its racial categorization, Nazism viewed what it called the Aryan race as the master race of the world—a race that was superior to all other races.[136] It viewed Aryans as being in racial conflict with a mixed race people, the Jews, whom the Nazis identified as a dangerous enemy of the Aryans. It also viewed a number of other peoples as dangerous to the well-being of the Aryan race. In order to preserve the perceived racial purity of the Aryan race, a set of race laws was introduced in 1935 which came to be known as the Nuremberg Laws. At first these laws only prevented sexual relations and marriages between Germans and Jews, but they were later extended to the "Gypsies, Negroes, and their bastard offspring", who were described by the Nazis as people of "alien blood".[137][138] Such relations between Aryans (cf. Aryan certificate) and non-Aryans were now punishable under the race laws as Rassenschande or "race defilement".[137] After the war began, the race defilement law was extended to include all foreigners (non-Germans).[139] At the bottom of the racial scale of non-Aryans were Jews, Romanis, Slavs[140] and blacks.[141] To maintain the "purity and strength" of the Aryan race, the Nazis eventually sought to exterminate Jews, Romani, Slavs and the physically and mentally disabled.[140][142] Other groups deemed "degenerate" and "asocial" who were not targeted for extermination, but were subjected to exclusionary treatment by the Nazi state, included homosexuals, blacks, Jehovah's Witnesses and political opponents.[142] One of Hitler's ambitions at the start of the war was to exterminate, expel or enslave most or all Slavs from Central and Eastern Europe in order to acquire living space for German settlers.[143]
The camps were liberated by the Allied forces between 1944 and 1945. The first major camp, Majdanek, was discovered by the advancing Soviets on July 23, 1944. Auschwitz was liberated, also by the Soviets, on January 27, 1945; Buchenwald by the Americans on April 11; Bergen-Belsen by the British on April 15; Dachau by the Americans on April 29; Ravensbrück by the Soviets on the same day; Mauthausen by the Americans on May 5; and Theresienstadt by the Soviets on May 8.[42] Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Nazis in 1943. Colonel William W. Quinn of the U.S. 7th Army said of Dachau: "There our troops found sights, sounds, and stenches horrible beyond belief, cruelties so enormous as to be incomprehensible to the normal mind."[43][44]
