Via the offices of the Sicherheitsdienst, the German security police, prison in Amsterdam, and the Westerbork transit camp, the people from the Secret Annex were put on transport to the Auschwitz-Birkenau concentration and extermination camp. The train journey took three days, during which Anne and over a thousand others were packed closely together in cattle wagons. There was little food and water and only a barrel for a toilet. 
Action T4 was a programme of systematic murder of the physically and mentally handicapped and patients in psychiatric hospitals that took place mainly from 1939 to 1941, and continued until the end of the war. Initially the victims were shot by the Einsatzgruppen and others; gas chambers and gas vans using carbon monoxide were used by early 1940.[312][313] Under the Law for the Prevention of Hereditarily Diseased Offspring, enacted on 14 July 1933, over 400,000 individuals underwent compulsory sterilisation.[314] Over half were those considered mentally deficient, which included not only people who scored poorly on intelligence tests, but those who deviated from expected standards of behaviour regarding thrift, sexual behaviour, and cleanliness. Most of the victims came from disadvantaged groups such as prostitutes, the poor, the homeless, and criminals.[315] Other groups persecuted and killed included Jehovah's Witnesses, homosexuals, social misfits, and members of the political and religious opposition.[186][316]

Surely there is nothing left to say about Anne Frank, except that there is everything left to say about her: all the books she never lived to write. For she was unquestionably a talented writer, possessed of both the ability and the commitment that real literature requires. Quite the opposite of how an influential Dutch historian described her work in the article that spurred her diary’s publication—a “diary by a child, this de profundis stammered out in a child’s voice”—Frank’s diary was not the work of a naif, but rather of a writer already planning future publication. Frank had begun the diary casually, but later sensed its potential; upon hearing a radio broadcast in March of 1944 calling on Dutch civilians to preserve diaries and other personal wartime documents, she immediately began to revise two years of previous entries, with a title (Het Achterhuis, or The House Behind) already in mind, along with pseudonyms for the hiding place’s residents. Nor were her revisions simple corrections or substitutions. They were thoughtful edits designed to draw the reader in, intentional and sophisticated. Her first entry in the original diary, for instance, begins with a long description of her birthday gifts (the blank diary being one of them), an entirely unself-conscious record by a 13-year-old girl. The first entry in her revised version, on the other hand, begins with a deeply self-aware and ironic pose: “It’s an odd idea for someone like me to keep a diary; not only because I have never done so before, but because it seems to me that neither I—nor for that matter anyone else—will be interested in the unbosomings of a 13-year-old schoolgirl.”
So, after standing almost continuously for thirteen hours in the cold November air, we were taken to our barracks. There we were permitted to lie down on straw for a short rest until morning. Not until the next day did we receive food and drink. Other groups were much worse off. Some were on their feet for twenty-six hours before they were taken to the barracks.
That month, Himmler ordered the evacuation of all camps, charging camp commanders with "making sure that not a single prisoner from the concentration camps falls alive into the hands of the enemy".[240] Beginning on 17 January, 56,000–58,000 Auschwitz detainees—over 20,000 from Auschwitz I and II, over 30,000 from subcamps, and two-thirds of them Jews—were evacuated under guard, largely on foot, in severe winter conditions, heading west.[241][242] Around 2,200 were evacuated by rail from two subcamps; fewer than 9,000 were left behind, deemed too sick to move.[243] During the marches, camp staff shot anyone too sick or exhausted to continue, or anyone stopping to urinate or tie a shoelace. SS officers walked behind the marchers killing anyone lagging behind who had not already been shot.[235] Peter Longerich estimates that a quarter of the detainees were thus killed.[236] Those who managed to walk to Wodzisław Śląski and Gliwice were sent on open freight cars, without food, to concentration camps in Germany: Bergen-Belsen, Buchenwald, Dachau, Flossenburg, Gross-Rosen, Mauthausen, Dora-Mittelbau, Ravensbruck, and Sachsenhausen.[244]
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.

Overall 268,657 male and 131,560 female prisoners were registered in Auschwitz, 400,207 in total.[182] Many prisoners were never registered and much evidence was destroyed by the SS in the final days of the war, making the number of victims hard to ascertain.[183] Himmler visited the camp on 17 July 1942 and watched a gassing; a few days later, according to Höss's post-war memoir, Höss received an order from Himmler, via Adolf Eichmann's office and SS commander Paul Blobel, that "[a]ll mass graves were to be opened and the corpses burned. In addition the ashes were to be disposed of in such a way that it would be impossible at some future time to calculate the number of corpses burned."[184]

The Nazis captured 5.75 million Soviet prisoners of war, more than they took from all the other Allied powers combined. Of these, they killed an estimated 3.3 million,[344] with 2.8 million of them being killed between June 1941 and January 1942.[345] Many POWs starved to death or resorted to cannibalism while being held in open-air pens at Auschwitz and elsewhere.[346]

German doctors performed a variety of experiments on prisoners at Auschwitz. SS doctors tested the efficacy of X-rays as a sterilization device by administering large doses to female prisoners. Carl Clauberg injected chemicals into women's uteruses in an effort to glue them shut. Prisoners were infected with spotted fever for vaccination research and exposed to toxic substances to study the effects.[125] In one experiment Bayer, then part of IG Farben, paid RM 150 each for 150 female inmates from Auschwitz (the camp had asked for RM 200 per woman), who were transferred to a Bayer facility to test an anesthetic. A Bayer employee wrote to Rudolf Höss: "The transport of 150 women arrived in good condition. However, we were unable to obtain conclusive results because they died during the experiments. We would kindly request that you send us another group of women to the same number and at the same price." The Bayer research was led at Auschwitz by Helmuth Vetter of Bayer/IG Farben, who was also an Auschwitz physician and SS captain, and by Auschwitz physicians Friedrich Entress and Eduard Wirths.[126]
While the Nazis maintained the nominal existence of state and regional governments in Germany itself, this policy was not extended to territories acquired after 1937. Even in German-speaking areas such as Austria, state and regional governments were formally disbanded as opposed to just being dis-empowered. After the Anschluss a new type of administrative unit was introduced called a Reichsgau. In these territories the Gauleiters also held the position of Reichsstatthalter, thereby formally combining the spheres of both party and state offices. The establishment of this type of district was subsequently carried out for any further territorial annexations of Germany both before and during World War II. Even the former territories of Prussia were never formally re-integrated into what was then Germany's largest state after being re-taken in the 1939 Polish campaign.
After Kristallnacht (the ‘Night of broken glass’) in November 1938, the Nazis and their supporters arrested many thousands of male Jews above the age of 14 years. They imprisoned them in camps for days or sometimes weeks. They were kept in poor conditions, given little food or water and subjected to brutal treatment and torture. When the German army invaded Poland on 1 September 1939, the SS set up many concentration camps to house Polish political prisoners and many thousands of Polish Jews. Many of the inmates of these camps were subjected to increasingly poor conditions. In addition they were subjected to forced labour, the result of which was often death.

Iraq: In 1986–89, Saddam Hussein conducted a genocidal campaign in which tens of thousands were murdered and thousands of Kurdish villages destroyed, including by bombing and chemical warfare. After the first Gulf War, the UN sought to establish a safe haven in parts of Kurdistan, and the United States and UK set up a no-fly zone. In 2003, the Kurdish peshmerga sided with the U.S.-led coalition against Saddam Hussein. In 2005, after a long struggle with Baghdad, the Iraqi Kurds won constitutional recognition of their autonomous region, and the Kurdistan Regional Government has since signed oil contracts with a number of Western oil companies as well as with Turkey. Iraqi Kurdistan has two main political parties, the Kurdistan Democratic Party (KDP) and the Patriotic Union of Kurdistan (PUK), both clan-based and patriarchal.
After December 1934, the SS became the only agency authorized to establish and manage facilities that were formally called concentration camps. Local civilian authorities did continue to establish and manage forced-labor camps and detention camps throughout Germany. In 1937, only four concentration camps were left: Dachau, near Munich; Sachsenhausen near Berlin; Buchenwald near Weimar; and Lichtenburg near Merseburg in Saxony for female prisoners.

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]

Movies were popular in Germany in the 1930s and 1940s, with admissions of over a billion people in 1942, 1943 and 1944.[478][479] By 1934, German regulations restricting currency exports made it impossible for US film makers to take their profits back to America, so the major film studios closed their German branches. Exports of German films plummeted, as their antisemitic content made them impossible to show in other countries. The two largest film companies, Universum Film AG and Tobis, were purchased by the Propaganda Ministry, which by 1939 was producing most German films. The productions were not always overtly propagandistic, but generally had a political subtext and followed party lines regarding themes and content. Scripts were pre-censored.[480]
Authors of books left the country in droves and some wrote material critical of the regime while in exile. Goebbels recommended that the remaining authors concentrate on books themed on Germanic myths and the concept of blood and soil. By the end of 1933, over a thousand books—most of them by Jewish authors or featuring Jewish characters—had been banned by the Nazi regime.[464] Nazi book burnings took place; nineteen such events were held on the night of 10 May 1933.[458] Tens of thousands of books from dozens of figures, including Albert Einstein, Sigmund Freud, Helen Keller, Alfred Kerr, Marcel Proust, Erich Maria Remarque, Upton Sinclair, Jakob Wassermann, H. G. Wells, and Émile Zola were publicly burned. Pacifist works, and literature espousing liberal, democratic values were targeted for destruction, as well as any writings supporting the Weimar Republic or those written by Jewish authors.[465]
The first 'bunker', with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra 'capacity' was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the 'bunkers' were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open. Between January 1942 and March 1943, 175,000 Jews were gassed to death here, of whom 105,000 were killed from January to March 1943.
Construction of crematorium I began at Auschwitz I at the end of June or beginning of July 1940.[26] Initially intended not for mass murder but for prisoners who had been executed or had otherwise died in the camps, the crematorium was in operation from August 1940 until July 1943, by which time the crematoria at Auschwitz II had taken over.[27] By May 1942 three ovens had been installed in crematorium I, which together could burn 340 bodies in 24 hours.[28]

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]
Germany and Europe as a whole was almost totally dependent on foreign oil imports.[122] In an attempt to resolve the shortage, in June 1942 Germany launched Fall Blau ("Case Blue"), an offensive against the Caucasian oilfields.[123] The Red Army launched a counter-offensive on 19 November and encircled the Axis forces, who were trapped in Stalingrad on 23 November.[124] Göring assured Hitler that the 6th Army could be supplied by air, but this turned out to be infeasible.[125] Hitler's refusal to allow a retreat led to the deaths of 200,000 German and Romanian soldiers; of the 91,000 men who surrendered in the city on 31 January 1943, only 6,000 survivors returned to Germany after the war.[126]
The SA leadership continued to apply pressure for greater political and military power. In response, Hitler used the Schutzstaffel (SS) and Gestapo to purge the entire SA leadership.[36] Hitler targeted SA Stabschef (Chief of Staff) Ernst Röhm and other SA leaders who—along with a number of Hitler's political adversaries (such as Gregor Strasser and former chancellor Kurt von Schleicher)—were arrested and shot.[37] Up to 200 people were killed from 30 June to 2 July 1934 in an event that became known as the Night of the Long Knives.[38]
In 1923, Hitler and his followers staged the Beer Hall Putsch in Munich, a failed takeover of the government in Bavaria, a state in southern Germany. Hitler had hoped that the “putsch,” or coup d’etat, would spark a larger revolution against the national government. In the aftermath of the Beer Hall Putsch, Hitler was convicted of treason and sentenced to five years in prison, but spent less than a year behind bars (during which time he dictated the first volume of “Mein Kampf,” or “My Struggle,” his political autobiography). The publicity surrounding the Beer Hall Putsch and Hitler’s subsequent trial turned him into a national figure. After his release from prison, he set about rebuilding the Nazi Party and attempting to gain power through the election process.

Besides tormenting us physically, the S. S. guard continually tried to torment us morally. Coming partly from the lowest proletariat, they tried to annoy us with quotations from the Stürmer. They asked us about the accuracy of supposed quotations from the Talmud which are purported to order the Jew to hate other nations, and especially all Christians. They had little success with these questions, since the prisoners had to answer almost without exception that they did not know more than the name of the Talmud.
In most camps, prisoners were forced to wear identifying overalls with colored badges according to their categorization: red triangles for Communists and other political prisoners, green triangles for common criminals, pink triangles for homosexual men, purple triangles for Jehovah's Witnesses, black triangles for asocials and the "work shy", yellow triangle for Jews, and later the brown triangle for Romanis.[30]
