The invasion conquered a huge area, including the Baltic states, Belarus, and west Ukraine. After the successful Battle of Smolensk in September 1941, Hitler ordered Army Group Centre to halt its advance to Moscow and temporarily divert its Panzer groups to aid in the encirclement of Leningrad and Kiev.[117] This pause provided the Red Army with an opportunity to mobilise fresh reserves. The Moscow offensive, which resumed in October 1941, ended disastrously in December.[118] On 7 December 1941, Japan attacked Pearl Harbor, Hawaii. Four days later, Germany declared war on the United States.[119]
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.
In 1919, army veteran Adolf Hitler, frustrated by Germany’s defeat in World War, which had left the nation economically depressed and politically unstable, joined a fledgling political organization called the German Workers’ Party. Founded earlier that same year by a small group of men including locksmith Anton Drexler (1884-1942) and journalist Karl Harrer (1890-1926), the party promoted German nationalism and anti-Semitism, and felt that the Treaty of Versailles, the peace settlement that ended the war, was extremely unjust to Germany by burdening it with reparations it could never pay. Hitler soon emerged as a charismatic public speaker and began attracting new members with speeches blaming Jews and Marxists for Germany’s problems and espousing extreme nationalism and the concept of an Aryan “master race.” In July 1921, he assumed leadership of the organization, which by then had been renamed the Nationalist Socialist German Workers’ (Nazi) Party.
For the man in charge of Auschwitz, the gas chamber was a welcome innovation. “I had always shuddered at the prospect of carrying out executions by shooting,” commandant Rudolf Höss wrote in a lengthy confession while awaiting execution after the war. “Many members of the Einsatzkommandos, unable to endure wading through blood any longer, had committed suicide. Some had even gone mad.”
On 24 December 1941 the resistance groups representing the various prisoner factions met in block 45 and agreed to cooperate. Fleming writes that it has not been possible to track Pilecki's early intelligence from the camp. Pilecki compiled two reports after he escaped in April 1943; the second, Raport W, detailed his life in Auschwitz I and estimated that 1.5 million people, mostly Jews, had been killed.[204] On 1 July 1942, the Polish Fortnightly Review published a report describing Birkenau, writing that "prisoners call this supplementary camp 'Paradisal', presumably because there is only one road, leading to Paradise". Reporting that inmates were being killed "through excessive work, torture and medical means", it noted the gassing of the Soviet prisoners of war and Polish inmates in Auschwitz I in September 1941, the first gassing in the camp. It said: "It is estimated that the Oswiecim camp can accommodate fifteen thousand prisoners, but as they die on a mass scale there is always room for new arrivals."[205]
A parallel system to the main camp in Auschwitz began to operate at the Birkenau camp by 1942. The exception, though, was that the majority of “showers” used to delouse the incoming prisoners proved to be gas chambers. At Birkenau, only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the “central sauna” before being assigned barracks as opposed to being sent directly to the death chambers.

In addition to the Nazi Party proper, several paramilitary groups existed which "supported" Nazi aims. All members of these paramilitary organisations were required to become regular Nazi Party members first and could then enlist in the group of their choice. An exception was the Waffen-SS, considered the military arm of the SS and Nazi Party, which during the Second World War allowed members to enlist without joining the Nazi Party. Foreign volunteers of the Waffen-SS were also not required to be members of the Nazi Party, although many joined local nationalist groups from their own countries with the same aims. Police officers, including members of the Gestapo, frequently held SS rank for administrative reasons (known as "rank parity") and were likewise not required to be members of the Nazi Party.
Officials and lawyers in the Third Reich were also intrigued by anti-miscegenation statutes, because the policing of sex was necessary to cleanse the Aryan race. Hitler, who had been largely asexual during his crucial years as a failing painter in Vienna, was obsessed with sex and blood. The United States at the time was a global leader in banning mixed marriages, going so far as to criminally punish those who defied the law. (Many of these laws were not struck down in the United States until the Supreme Court’s 1967 Loving v. Virginia case.) The Prussian Memorandum explicitly invoked U.S. laws that promoted segregation to maintain racial purity, and the sexual morality of white women in particular. Similarly, the third Nuremburg Law expressly forbid marriages and extra-marital relations between Germans and Jews, and promised hard labor in prison for law-breakers. The more one reads about the American and Nazi fixation on race, the more evident it becomes that at the very core of racist ideology is a primal fear of sexual inadequacy, of pollution, of mixing. Racial nationalism, the ideology of the Nazis, took this idea to its logical end.

In 1976, Otto Frank took action against Heinz Roth of Frankfurt, who published pamphlets stating that the diary was "a forgery". The judge ruled that if Roth was to publish any further statements he would be subjected to a fine of 500,000 German marks and a six-month jail sentence. Roth appealed against the court's decision. He died in 1978, and after a year his appeal was rejected.[94]
Hitler told a party leader in 1934: "The economic system of our day is the creation of the Jews".[262] Hitler said to Benito Mussolini that capitalism had "run its course".[262] Hitler also said that the business bourgeoisie "know nothing except their profit. 'Fatherland' is only a word for them."[263] Hitler was personally disgusted with the ruling bourgeois elites of Germany during the period of the Weimar Republic, who he referred to as "cowardly shits".[264]
Racism and antisemitism were basic tenets of the NSDAP and the Nazi regime. Nazi Germany's racial policy was based on their belief in the existence of a superior master race. The Nazis postulated the existence of a racial conflict between the Aryan master race and inferior races, particularly Jews, who were viewed as a mixed race that had infiltrated society and were responsible for the exploitation and repression of the Aryan race.[298]
“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.”
Germany regained control of the Saarland through a referendum held in 1935 and annexed Austria in the Anschluss of 1938.[164] The Munich Agreement of 1938 gave Germany control of the Sudetenland, and they seized the remainder of Czechoslovakia six months later.[70] Under threat of invasion by sea, Lithuania surrendered the Memel district in March 1939.[165]
By the end of the war, the number of people who had died in the concentration camps, from all causes—starvation, sickness, exhaustion, beating, shooting, gassing—was more than eight hundred thousand. The figure does not include the hundreds of thousands of Jews gassed on arrival at Auschwitz. If the K.L. were indeed a battlefront, as the Death’s-Head S.S. liked to believe, the deaths, in the course of twelve years, roughly equalled the casualties sustained by the Axis during the Battle of Stalingrad, among the deadliest actual engagements of the war. But in the camps the Nazis fought against helpless enemies. Considered as prisons, too, the K.L. were paradoxical: it was impossible to correct or rehabilitate people whose very nature, according to Nazi propaganda, was criminal or sick. And as economic institutions they were utterly counterproductive, wasting huge numbers of lives even as the need for workers in Germany became more and more acute.
On about 17 January or 18 January 1945, the SS dragged thousands of us out of the camp to walk to Ravensbrück concentration camp deep into central Germany. I don’t really know why. We were in terrible straits with no proper clothes, nothing suitable for marching through the snow. It was as if the cruelty would never end. If anyone sat down out of exhaustion, they were shot. Later we were transported yet again, and my aunt Piri became ill and was killed.
Up to this point, though, Auschwitz-Birkenau accounted for “only” 11 percent of the victims of the “Final Solution.” In August 1942, however, construction began on four large-scale gassing facilities. It appears from the plans that the first two gas chambers were adapted from mortuaries which, with the huge crematoria attached to them, were initially intended to cope with mortalities amongst the slave labor force in the camp, now approaching 100,000 and subject to a horrifying death rate. But from the autumn of 1942, it seems clear that the SS planners and civilian contractors were intending to build a mass-murder plant.
The main camp population grew from 18,000 in December 1942 to 30,000 in March 1943. In July or August 1941, Himmler briefed Höss about the 'Final Solution'. On September 3th, 1941, Soviet POWs at the Auschwitz main camp were used in trials of the poison gas Zyklon-B. This poison gas was produced by the German company "Degesch" (Deutsche Gesellschaft zur Schädlingsbekämpfung). The were gassed in underground cells in Block 11. After this trial, a gas chamber was rigged-up just outside the main camp and in February 1942, two temporary gas chambers opened at Birkenau. The crematories were built by the German company "Topf & son" located at Erfurt.
The site was first suggested as a concentration camp for Polish prisoners by SS-Oberführer Arpad Wigand, an aide to Erich von dem Bach-Zelewski, Higher SS and Police Leader for Silesia. After this part of Poland was annexed by Nazi Germany, Oświęcim (Auschwitz) was located administratively in Germany, in the Province of Upper Silesia, Regierungsbezirk Kattowitz, Landkreis Bielitz. Bach-Zelewski had been searching for a site to hold prisoners in the Silesia region, as the local prisons were filled to capacity. Richard Glücks, head of the Concentration Camps Inspectorate, sent former Sachsenhausen concentration camp commandant Walter Eisfeld to inspect the site, which housed 16 dilapidated one-story buildings that had served as an Austrian and later Polish Army barracks and a camp for transient workers.[3] German citizens were offered tax concessions and other benefits if they would relocate to the area.[33] By October 1943, more than 6,000 Reich Germans had arrived.[34] The Nazis planned to build a model modern residential area for incoming Germans, including schools, playing fields, and other amenities. Some of the plans went forward, including the construction of several hundred apartments, but many were never fully implemented.[35] Basic amenities such as water and sewage disposal were inadequate, and water-borne illnesses were commonplace.[36]
In 1942, after the death of Armaments Minister Fritz Todt, Hitler appointed Albert Speer as his replacement.[274] Wartime rationing of consumer goods led to an increase in personal savings, funds which were in turn lent to the government to support the war effort.[275] By 1944, the war was consuming 75 percent of Germany's gross domestic product, compared to 60 percent in the Soviet Union and 55 percent in Britain.[276] Speer improved production by centralising planning and control, reducing production of consumer goods, and using forced labour and slavery.[277][278] The wartime economy eventually relied heavily upon the large-scale employment of slave labour. Germany imported and enslaved some 12 million people from 20 European countries to work in factories and on farms. Approximately 75 percent were Eastern European.[279] Many were casualties of Allied bombing, as they received poor air raid protection. Poor living conditions led to high rates of sickness, injury, and death, as well as sabotage and criminal activity.[280] The wartime economy also relied upon large-scale robbery, initially through the state seizing the property of Jewish citizens and later by plundering the resources of occupied territories.[281]
But, in May 1944, a railroad spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944. From then to November 1944, when all the other death camps had been abandoned, Birkenau surpassed all previous records for mass killing. The Hungarian deportations and the liquidation of the remaining Polish ghettos, such as Lodz, resulted in the gassing of 585,000 Jews. This period made Auschwitz-Birkenau into the most notorious killing site of all time.
The process of selection and murder was carefully planned and organized. When a train stopped at the platform, veteran prisoners received the victims and gathered their belongings in several barracks in an area known as “Kanada.” The arrivals were lined up in two columns – men and boys in one, women and girls in the other – and SS physicians performed a selection.  The criterion was the appearance of the prisoners, whose fate, for labor or for death, was determined at will. Before they entered the chamber, they were told that they were about to be disinfected and ordered to undress. The doors of the chamber were locked and the gas was introduced. After the victims were murdered, their gold teeth were extracted and women’s hair was shorn by the Sonderkommando – groups of Jews forced to work in the crematoria. The bodies were hauled to the crematorium furnaces for incineration, the bones were pulverized and the ashes were scattered in the fields.
When the Nazi Party emerged from obscurity to become a major political force after 1929, the conservative faction rapidly gained more influence, as wealthy donors took an interest in the Nazis as a potential bulwark against communism.[39] The Nazi Party had previously been financed almost entirely from membership dues, but after 1929 its leadership began actively seeking donations from German industrialists, and Hitler began holding dozens of fundraising meetings with business leaders.[40] In the midst of the Great Depression, facing the possibility of economic ruin on the one hand and a Communist or Social Democratic government on the other hand, German business increasingly turned to Nazism as offering a way out of the situation, by promising a state-driven economy that would support, rather than attack, existing business interests.[41] By January 1933, the Nazi Party had secured the support of important sectors of German industry, mainly among the steel and coal producers, the insurance business and the chemical industry.[42]
A new type of court, the Volksgerichtshof ("People's Court"), was established in 1934 to deal with political cases.[209] This court handed out over 5,000 death sentences until its dissolution in 1945.[210] The death penalty could be issued for offences such as being a communist, printing seditious leaflets, or even making jokes about Hitler or other officials.[211] The Gestapo was in charge of investigative policing to enforce National Socialist ideology as they located and confined political offenders, Jews, and others deemed undesirable.[212] Political offenders who were released from prison were often immediately re-arrested by the Gestapo and confined in a concentration camp.[213]
At the same time, public interest in the camp has never been higher. Visits have doubled this decade, from 492,500 in 2001 to more than 1 million in 2009. Since Poland joined the European Union in 2004, Krakow has become a popular destination for foreign tourists, and Auschwitz is a must stop on many itineraries. A visit is also part of education programs in Israel, Britain and other countries. On peak days, as many as 30,000 visitors file through the camp’s buildings.
Special “political units on alert” (Politische Bereitschaften) originally guarded the SS concentration camps. They were renamed “SS Guard Units” (SS-Wachverbände) in 1935 and “SS Death's-Head Units” (SS-Totenkopfverbände) in April 1936. One SS Death's-Head Unit was assigned to each concentration camp. After 1936, the camp administration, including the commandant, was also a part of the SS Death's-Head Unit.
Radical Antisemitism was promoted by prominent advocates of Völkisch nationalism, including Eugen Diederichs, Paul de Lagarde and Julius Langbehn.[69] De Lagarde called the Jews a "bacillus, the carriers of decay ... who pollute every national culture ... and destroy all faiths with their materialistic liberalism" and he called for the extermination of the Jews.[89] Langbehn called for a war of annihilation against the Jews, and his genocidal policies were later published by the Nazis and given to soldiers on the front during World War II.[89] One antisemitic ideologue of the period, Friedrich Lange, even used the term "National Socialism" to describe his own anti-capitalist take on the Völkisch nationalist template.[90]
The Republic of Czechoslovakia was home to a substantial minority of Germans, who lived mostly in the Sudetenland. Under pressure from separatist groups within the Sudeten German Party, the Czechoslovak government offered economic concessions to the region.[66] Hitler decided to incorporate not just the Sudetenland but all of Czechoslovakia into the Reich.[67] The Nazis undertook a propaganda campaign to try to generate support for an invasion.[68] Top German military leaders opposed the plan, as Germany was not yet ready for war.[69]
One could call this a simple mistake, except that it echoed a similar incident the previous year, when visitors noticed a discrepancy in the museum’s audioguide displays. Each audioguide language was represented by a national flag—with the exception of Hebrew, which was represented only by the language’s name in its alphabet. The display was eventually corrected to include the Israeli flag.
Victor Kugler and Johannes Kleiman were arrested and jailed at the penal camp for enemies of the regime at Amersfoort. Kleiman was released after seven weeks, but Kugler was held in various work camps until the war's end.[39] Miep Gies and Bep Voskuijl were questioned and threatened by the Security Police but not detained. They returned to the Achterhuis the following day, and found Anne's papers strewn on the floor. They collected them, as well as several family photograph albums, and Gies resolved to return them to Anne after the war. On 7 August 1944, Gies attempted to facilitate the release of the prisoners by confronting Silberbauer and offering him money to intervene, but he refused.[40]
According to the numbers provided by the US Holocaust Memorial Museum, Auschwitz was the site of the most deaths (1.1 million) of any of the six dedicated extermination camps. By these estimates, Auschwitz was the site of at least one out of every six deaths during the Holocaust. The only camp with comparable figures was Treblinka in north-east Poland, where about 850,000 are thought to have died.
Auschwitz I (or "the Main Camp") was the original camp. This camp housed prisoners, was the location of medical experiments, and the site of Block 11 (a place of severe torture) and the Black Wall (a place of execution). At the entrance of Auschwitz, I stood the infamous sign that stated "Arbeit Macht Frei" ("work makes one free"). Auschwitz I also housed the Nazi staff that ran the entire camp complex.
Auschwitz-Birkenau, the largest of the concentration and extermination camps established on Polish soil, served concurrently as a labor camp and as a center for the rapid extermination of Jews. Chosen as the central location for the annihilation of the Jewish people, it was equipped with several extermination facilities and crematoria. Extermination was carried out by means of Zyklon B gas, a substance that had previously been tested on Russian prisoners of war.

Gies had saved everything she could from the secret annex, including Anne’s diary, her short stories, and favorite quotes from other writers. Otto read the diary, which Anne had rewritten in hopes of publishing after the war, typed it, and began sharing it with family and friends interested in reading it. A newspaper article by historian Jan Romein called Kinderstem (A Child’s Voice) led to the first publication of Het Achterhuis. Dagboekbrieven 14 july 1942 – 1 augustus 1944 (The Annex: Diary Notes from 14 June – 1 August).
I married a Polish Jew and we settled in Germany, the “Täterland” – the land of the perpetrator – after being forced out of Czechoslovakia after the collapse of the Prague Spring in 1968. It does sometimes feel like a strange decision to live in Germany because the Holocaust is just so omnipresent here and there is a growing antisemitism that scares me, especially when you feel it in Germany, of all places, which is why I always repeat what Primo Levi wrote: “What happened can happen again.”
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]
On July 15, 1944, three weeks before the hiding place where she lived with her family and several others was discovered, Anne Frank wrote in her diary: “It’s a wonder I haven’t abandoned all my ideals, they seem so absurd and impractical. Yet I cling to them because I still believe, in spite of everything, that people are truly good at heart.” Anne Frank’s diary, particularly these sentences, became one of the central symbols of the Holocaust and of humanity faced with suffering: the strength of spirit that led a young girl to write such words after two years of imprisonment hidden in a small, crowded attic, decreed on her by senseless evil; and the opening which her words offer for a new era of hope and reconciliation after a world war that claimed tens of millions of victims. These words aroused great admiration for her diary and for the girl herself. Translated into more than fifty languages, the diary sold more than thirty million copies all over the world. Streets and squares, coins and stamps bear Anne’s name, along with prizes, conventions, exhibits, memorials, schools and youth institutions, to say nothing of films and plays that bring her diary to life, and thorough research of various kinds into her character and her diary, its translations and the different uses that have been made and still are being made of it.
“Responsibility is extremely direct in face-to-face shootings,” Dwork says. “In gassing and cremation, each person is given only a small part.” Eventually, Germans took part only by tossing the cyanide pellets into the gas chambers. Everything else—herding prisoners into the chambers, ripping out gold fillings and loading corpses into the crematoria—was handled by groups of prisoners, known as Sonderkommandos.
Kamil Bedkowski, 33, worked as an art conservator in Britain for eight years, even restoring ceiling frescoes at Windsor Castle. Now he is on the team shoring up the crumbling brick barracks of Birkenau where thousands slept at a time, crammed into decaying three-level wooden bunks. “This is the most challenging project I’ve ever worked on,” he said.
The political programme espoused by Hitler and the NSDAP brought about a world war, leaving behind a devastated and impoverished Europe. Germany itself suffered wholesale destruction, characterised as Stunde Null (Zero Hour).[487] The number of civilians killed during the Second World War was unprecedented in the history of warfare.[488] As a result, Nazi ideology and the actions taken by the regime are almost universally regarded as gravely immoral.[489] Historians, philosophers, and politicians often use the word "evil" to describe Hitler and the Nazi regime.[490] Interest in Nazi Germany continues in the media and the academic world. While Evans remarks that the era "exerts an almost universal appeal because its murderous racism stands as a warning to the whole of humanity",[491] young neo-Nazis enjoy the shock value the use Nazi symbols or slogans provides.[492] The display or use of Nazi symbolism such as flags, swastikas, or greetings is illegal in Germany and Austria.[493][494]
I’m often asked how I have coped. I never went to a psychologist and I never will. Quite simply, I kept it at a distance. I saw and understood, and yet I didn’t. I’ve never cried over the columns of children and mothers I saw. When I was in Auschwitz I thought: ‘This is not actually on earth.’ It was a system of masters and slaves, gods and subhumans and I thought to myself: ‘No one knows about it. It’s the forest, surrounded by multiple layers of fence, it’s not actually real.’ I never let it penetrate that my parents were killed and I even thought: ‘After this we’re going home and everyone will be there again.’ Those who never managed to keep it distant killed themselves.
Agrarian policies were also important to the Nazis since they corresponded not just to the economy but to their geopolitical conception of Lebensraum as well. For Hitler, the acquisition of land and soil was requisite in moulding the German economy.[233] To tie farmers to their land, selling agricultural land was prohibited.[234] Farm ownership remained private, but business monopoly rights were granted to marketing boards to control production and prices with a quota system.[235] The "Hereditary Farm Law of 1933" established a cartel structure under a government body known as the Reichsnährstand (RNST) which determined "everything from what seeds and fertilizers were used to how land was inherited".[236]

were of a revolutionary nature: destruction of existing political and social structures and their supporting elites; profound dispain for civic order, for human and moral values, for Habsburg and Hohenzollern, for liberal and Marxist ideas. The middle class and middle-class values, bourgeois nationalism and capitalism, the professionals, the intelligentsia and the upper class were dealt the sharpest rebuff. These were the groups which had to be uprooted...[278]

"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 Sondergerichte had a strong deterrent effect during the first years of their operation, since their rapid and severe sentencing was feared."
