Fleeing Germans also torched a couple of dozen of the wooden barracks at Birkenau. Many of the camp buildings that were left largely intact were later taken apart by Poles desperate for shelter. Birkenau remains the starkest, most tangible, most haunting reminder of what Dwork says was the “greatest catastrophe Western civilization permitted, and endured.”

The impulse to separate some groups of people from the category of the human is, however, a universal one. The enemies we kill in war, the convicted prisoners we lock up for life, even the distant workers who manufacture our clothes and toys—how could any society function if the full humanity of all these were taken into account? In a decent society, there are laws to resist such dehumanization, and institutional and moral forces to protest it. When guards at Rikers Island beat a prisoner to death, or when workers in China making iPhones begin to commit suicide out of despair, we regard these as intolerable evils that must be cured. It is when a society decides that some people deserve to be treated this way—that it is not just inevitable but right to deprive whole categories of people of their humanity—that a crime on the scale of the K.L. becomes a possibility. It is a crime that has been repeated too many times, in too many places, for us to dismiss it with the simple promise of never again. ♦
On the night of the 27 February 1933 and 28 February 1933, someone set the Reichstag building on fire. This was the building where the German Parliament held their meetings. The Nazis blamed the communists. Opponents of the Nazis said that the Nazis themselves had done it to come to power. On the very same day, an emergency law called Reichstagsbrandverordnung was passed. The government claimed it was to protect the state from people trying to hurt the country. With this law, most of the civil rights of the Weimar Republic did not count any longer. The Nazis used this against the other political parties. Members of the communist and social-democratic parties were put into prison or killed.
When Germany invaded Poland in September 1939, triggering World War II, Adolf Hitler ordered that the Polish leadership and intelligentsia be destroyed.[16] Approximately 65,000 civilians, viewed as inferior to the Aryan master race, had been killed by the end of 1939. In addition to leaders of Polish society, the Nazis killed Jews, prostitutes, the Roma, and the mentally ill.[17][18] SS-Obergruppenführer Reinhard Heydrich, then head of the Gestapo, ordered on 21 September 1939 that Polish Jews be rounded up and concentrated into cities with good rail links. Initially the intention was to deport them to points further east, or possibly to Madagascar.[19] Two years later, in June 1941, in an attempt to obtain new territory, Hitler invaded the Soviet Union.[8]
As Soviet troops closed in on Auschwitz in late January 1945, the SS hurriedly evacuated some 56,000 prisoners on death marches to the west, then blew up the Birkenau gas chambers and crematoria to erase evidence of the mass murders. The Red Army liberated Auschwitz on January 27, 1945. Some 6,000 people were still alive at Birkenau. Another 1,000 were found at the main camp.
The first party that attempted to combine nationalism and socialism was the (Austria-Hungary) German Workers' Party, which predominantly aimed to solve the conflict between the Austrian Germans and the Czechs in the multi-ethnic Austrian Empire, then part of Austria-Hungary.[70] In 1896 the German politician Friedrich Naumann formed the National-Social Association which aimed to combine German nationalism and a non-Marxist form of socialism together; the attempt turned out to be futile and the idea of linking nationalism with socialism quickly became equated with antisemites, extreme German nationalists and the Völkisch movement in general.[27]

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]
In most of the camps discovered by the Soviets, almost all the prisoners had already been removed, leaving only a few thousand alive—7,000 inmates were found in Auschwitz, including 180 children who had been experimented on by doctors.[45] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division,[46] 13,000 corpses lay unburied, and another 10,000 died from typhus or malnutrition over the following weeks.[47] The British forced the remaining SS guards to gather up the corpses and place them in mass graves.[48]
Even in the evening, when we had sunk wearily on our straw cots, we were not safe from the cruel whims of the S. S. men. If we didn't jump up quickly enough at their sudden appearance they made us practise jumping up and lying down until we were exhausted, or they had the entire ward line up outside the barracks in the cold and stand for half an hour or longer in the attitude of the 'Saxon Salute—that is, with hands folded behind the head. If an S.S. man entered the barracks in the daytime and was not seen at once by the inmate cleaning up and not saluted, then he might very well have the 'culprit' crawl in and out of the straw a dozen times for punishment. The guards were like mean children who torment animals.
Before he joined the Bavarian Army to fight in World War I, Hitler had lived a bohemian lifestyle as a petty street watercolour artist in Vienna and Munich and he maintained elements of this lifestyle later on, going to bed very late and rising in the afternoon, even after he became Chancellor and then Führer.[47] After the war, his battalion was absorbed by the Bavarian Soviet Republic from 1918 to 1919, where he was elected Deputy Battalion Representative. According to historian Thomas Weber, Hitler attended the funeral of communist Kurt Eisner (a German Jew), wearing a black mourning armband on one arm and a red communist armband on the other,[48] which he took as evidence that Hitler's political beliefs had not yet solidified.[48] In Mein Kampf, Hitler never mentioned any service with the Bavarian Soviet Republic and he stated that he became an antisemite in 1913 during his years in Vienna. This statement has been disputed by the contention that he was not an antisemite at that time,[49] even though it is well established that he read many antisemitic tracts and journals during time and admired Karl Lueger, the antisemitic mayor of Vienna.[50] Hitler altered his political views in response to the signing of the Treaty of Versailles in June 1919 and it was then that he became an antisemitic, German nationalist.[49]
Within the Nazi Party, the faction associated with anti-capitalist beliefs was the Sturmabteilung (SA), a paramilitary wing led by Ernst Röhm. The SA had a complicated relationship with the rest of the party, giving both Röhm himself and local SA leaders significant autonomy.[268] Different local leaders would even promote different political ideas in their units, including "nationalistic, socialistic, anti-Semitic, racist, völkisch, or conservative ideas."[269] There was tension between the SA and Hitler, especially from 1930 onward, as Hitler's "increasingly close association with big industrial interests and traditional rightist forces" caused many in the SA to distrust him.[270] The SA regarded Hitler's seizure of power in 1933 as a "first revolution" against the left, and some voices within the ranks began arguing for a "second revolution" against the right.[271] After engaging in violence against the left in 1933, Röhm's SA also began attacks against individuals deemed to be associated with conservative reaction.[45] Hitler saw Röhm's independent actions as violating and possibly threatening his leadership, as well as jeopardising the regime by alienating the conservative President Paul von Hindenburg and the conservative-oriented German Army.[46] This resulted in Hitler purging Röhm and other radical members of the SA in 1934, during the Night of the Long Knives.[46]
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).
SS formations committed many war crimes against civilians and allied servicemen.[238] From 1935 onward, the SS spearheaded the persecution of Jews, who were rounded up into ghettos and concentration camps.[239] With the outbreak of World War II, the SS Einsatzgruppen units followed the army into Poland and the Soviet Union, where from 1941 to 1945 they killed more than two million people, including 1.3 million Jews.[240] A third of the Einsatzgruppen members were recruited from Waffen-SS personnel.[241][242] The SS-Totenkopfverbände (death's head units) ran the concentration camps and extermination camps, where millions more were killed.[243][244] Up to 60,000 Waffen-SS men served in the camps.[245]
In 1963, Otto Frank and his second wife, Elfriede Geiringer-Markovits, set up the Anne Frank Fonds as a charitable foundation, based in Basel, Switzerland. The Fonds raises money to donate to causes "as it sees fit". Upon his death, Otto willed the diary's copyright to the Fonds, on the provision that the first 80,000 Swiss francs in income each year was to be distributed to his heirs. Any income above this figure is to be retained by the Fonds for use on whatever projects its administrators considered worthy. It provides funding for the medical treatment of the Righteous Among the Nations on a yearly basis. The Fonds aims to educate young people against racism, and loaned some of Anne Frank's papers to the United States Holocaust Memorial Museum in Washington for an exhibition in 2003. Its annual report that year outlined its efforts to contribute on a global level, with support for projects in Germany, Israel, India, Switzerland, the United Kingdom, and the United States.[105]
Next to physical labor, military drill played an important part, especially for the older men. Still to-day I can hear the command: 'Eyes right! Eyes front!' The drill consisted mainly of marching in large formations and in turns and practising the salute—a quick removal of the cap. Those who did not greet a passing S.S. man with this procedure laid themselves open to severe punishment. A sixty-five-year-old lawyer, who in spite of glasses could see very little, did not salute a passing 'superior officer,' and was struck so that his glasses were broken. His excuse that he was extremely nearsighted was answered with curses.
By mid-1942, the majority of those being sent by the Nazis to Auschwitz were Jews. Upon arriving at the camp, detainees were examined by Nazi doctors. Those detainees considered unfit for work, including young children, the elderly, pregnant women and the infirm, were immediately ordered to take showers. However, the bathhouses to which they marched were disguised gas chambers. Once inside, the prisoners were exposed to Zyklon-B poison gas. Individuals marked as unfit for work were never officially registered as Auschwitz inmates. For this reason, it is impossible to calculate the number of lives lost in the camp.

In June 2016, the Auschwitz-Birkenau museum in the Polish town of Oswiecim re-discovered over 16,000 personal items belonging to victims of Auschwitz-Birkenau that had been lost in 1968. The items were originally discovered in 1967 by archaeologists excavating the concentration camp site, and were placed in 48 cardboard boxes in the Polish Academy of Sciences in Warsaw before being lost due to an anti-Semitic communist regime coming to power in 1968.
Hitler was appointed Chancellor of Germany by the President of the Weimar Republic, Paul von Hindenburg, on 30 January 1933. The NSDAP then began to eliminate all political opposition and consolidate its power. Hindenburg died on 2 August 1934 and Hitler became dictator of Germany by merging the offices and powers of the Chancellery and Presidency. A national referendum held 19 August 1934 confirmed Hitler as sole Führer (leader) of Germany. All power was centralised in Hitler's person and his word became the highest law. The government was not a coordinated, co-operating body, but a collection of factions struggling for power and Hitler's favour. In the midst of the Great Depression, the Nazis restored economic stability and ended mass unemployment using heavy military spending and a mixed economy. Extensive public works were undertaken, including the construction of Autobahnen (motorways). The return to economic stability boosted the regime's popularity.
During the 1920s, Hitler urged disparate Nazi factions to unite in opposition to Jewish Bolshevism.[251] Hitler asserted that the "three vices" of "Jewish Marxism" were democracy, pacifism and internationalism.[252] The Communist movement, the trade unions, the Social Democratic Party and the left-wing press were all considered to be Jewish-controlled and part of the "international Jewish conspiracy" to weaken the German nation by promoting internal disunity through class struggle.[53] The Nazis also believed that the Jews had instigated the Bolshevik revolution in Russia and that Communists had stabbed Germany in the back and caused it to lose the First World War.[253] They further argued that modern cultural trends of the 1920s (such as jazz music and cubist art) represented "cultural Bolshevism" and were part of a political assault aimed at the spiritual degeneration of the German Volk.[253] Joseph Goebbels published a pamphlet titled The Nazi-Sozi which gave brief points of how National Socialism differed from Marxism.[254] In 1930, Hitler said: "Our adopted term 'Socialist' has nothing to do with Marxist Socialism. Marxism is anti-property; true Socialism is not".[255]

Through the 1920s, Hitler gave speech after speech in which he stated that unemployment, rampant inflation, hunger and economic stagnation in postwar Germany would continue until there was a total revolution in German life. Most problems could be solved, he explained, if communists and Jews were driven from the nation. His fiery speeches swelled the ranks of the Nazi Party, especially among young, economically disadvantaged Germans.

Polished boots slightly apart, his thumb resting on his pistol belt, Mengele surveyed his prey with those dead gimlet eyes. Death to the left, life to the right. Four hundred thousand souls - babies, small children, young girls, mothers, fathers, and grandparents - are said to have been casually waved to the lefthand side with a flick of the cane clasped in a gloved hand.
In “Ravensbrück,” Helm gives a further example of the erratic way the Nazis treated their own regulations, even late in the war. In 1943, Himmler agreed to allow the Red Cross to deliver food parcels to some prisoners in the camps. To send a parcel, however, the Red Cross had to mark it with the name, number, and camp location of the recipient; requests for these details were always refused, so that there was no way to get desperately needed supplies into the camps. Yet when Wanda Hjort, a young Norwegian woman living in Germany, got hold of some prisoners’ names and numbers—thanks to inmates who smuggled the information to her when she visited the camp at Sachsenhausen—she was able to pass them on to the Norwegian Red Cross, whose packages were duly delivered. This game of hide-and-seek with the rules, this combination of hyper-regimentation and anarchy, is what makes Kafka’s “The Trial” seem to foretell the Nazi regime.
Early camps, usually without proper infrastructure, sprang up everywhere in Germany after Hitler became Chancellor in January 1933: rising "like mushrooms after the rain", Himmler recollected.[51] These early camps, also called "Wild camps" because some were set up with little supervision from higher authorities, were overseen by Nazi paramilitaries, by political-police forces, and sometimes by local police authorities. They utilized any lockable larger space, for example: engine rooms, brewery floors, storage facilities, cellars, etc.[52]
