When three refugee physicists confided to Einstein that the Nazis might be developing a new weapon—an atomic bomb—he decided to act. Despite his previous appeals for governments to dispense with the weapons of war, Einstein wrote to President Franklin Roosevelt in 1939 alerting him to "a new phenomenon that would...lead to the construction of bombs" and suggested that the United States accelerate its atomic weapons research program. Scholars debate the effect of this letter. Einstein signed it in 1939 and the Manhattan Project, the U.S. effort to build the bomb, began in 1941.

A Nazi era school textbook for German students entitled Heredity and Racial Biology for Students written by Jakob Graf described to students the Nazi conception of the Aryan race in a section titled "The Aryan: The Creative Force in Human History".[136] Graf claimed that the original Aryans developed from Nordic peoples who invaded ancient India and launched the initial development of Aryan culture there that later spread to ancient Persia and he claimed that the Aryan presence in Persia was what was responsible for its development into an empire.[136] He claimed that ancient Greek culture was developed by Nordic peoples due to paintings of the time which showed Greeks who were tall, light-skinned, light-eyed, blond-haired people.[136] He said that the Roman Empire was developed by the Italics who were related to the Celts who were also a Nordic people.[136] He believed that the vanishing of the Nordic component of the populations in Greece and Rome led to their downfall.[136] The Renaissance was claimed to have developed in the Western Roman Empire because of the Germanic invasions that brought new Nordic blood to the Empire's lands, such as the presence of Nordic blood in the Lombards (referred to as Longobards in the book); that remnants of the western Goths were responsible for the creation of the Spanish Empire; and that the heritage of the Franks, Goths and Germanic peoples in France was what was responsible for its rise as a major power.[136] He claimed that the rise of the Russian Empire was due to its leadership by people of Norman descent.[136] He described the rise of Anglo-Saxon societies in North America, South Africa and Australia as being the result of the Nordic heritage of Anglo-Saxons.[136] He concluded these points by saying: "Everywhere Nordic creative power has built mighty empires with high-minded ideas, and to this very day Aryan languages and cultural values are spread over a large part of the world, though the creative Nordic blood has long since vanished in many places".[136]
In March 1941, Himmler ordered a second, larger complex to be built next to the original camp. It was called Auschwitz II - Birkenau. The camp at Birkenau was divided into subsections surrounded by electric fences with barbed wire. During 1943 and 1944 the BIIb section became the location of the „Terezín family camp“. At its summit, Birkenau had over 100 000 inmates. In March 1942, the Auschwitz III camp was set up at nearby Monowitz, also known as Buna Monowitz. German company I.G. Farben set up a synthetic rubber factory there, in which it used the prisoners' slave labour. Auschwitz also had a further 45 auxiliary camps, where prisoners were forced to engage in slave labour, mostly for German companies.

Extensive propaganda was used to spread the regime's goals and ideals. Upon the death of German president Paul von Hindenburg in August 1934, Hitler assumed the powers of the presidency. The army swore an oath of personal loyalty to him. Hitler's dictatorship rested on his position as Reich President (head of state), Reich Chancellor (head of government), and Fuehrer (head of the Nazi party). According to the "Fuehrer principle," Hitler stood outside the legal state and determined matters of policy himself.
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.
The failure of the factory, as Wachsmann describes it, was indicative of the incompetence of the S.S. and the inconsistency of its vision for the camps. To turn prisoners into effective laborers would have required giving them adequate food and rest, not to mention training and equipment. It would have meant treating them like employees rather than like enemies. But the ideological momentum of the camps made this inconceivable. Labor was seen as a punishment and a weapon, which meant that it had to be extorted under the worst possible circumstances. Prisoners were made to build the factory in the depths of winter, with no coats or gloves, and no tools. “Inmates carried piles of sand in their uniforms,” Wachsmann writes, while others “moved large mounds of earth on rickety wooden stretchers or shifted sacks of cement on their shoulders.” Four hundred and twenty-nine prisoners died and countless more were injured, yet in the end not a single brick was produced.
In early 1942, mass exterminations were moved to two provisional gas chambers (the "red house" and "white house", known as bunkers 1 and 2) in Auschwitz II, while the larger crematoria (II, III, IV, and V) were under construction. Bunker 2 was temporarily reactivated from May to November 1944, when large numbers of Hungarian Jews were gassed.[162] In summer 1944 the combined capacity of the crematoria and outdoor incineration pits was 20,000 bodies per day.[163] A planned sixth facility—crematorium VI—was never built.[164] Prisoners were transported from all over German-occupied Europe by rail, arriving in daily convoys.[165] By July 1942, the SS were conducting "selections". Incoming Jews were segregated; those deemed able to work were sent to the selection officer's right and admitted into the camp, and those deemed unfit for labor were sent to the left and immediately gassed.[166] The group selected to die, about three-quarters of the total,[c] included almost all children, women with small children, the elderly, and all those who appeared on brief and superficial inspection by an SS doctor not to be fit for work.[168]
The fortified walls, barbed wire, railway sidings, platforms, barracks, gallows, gas chambers and crematoria at Auschwitz Birkenau show clearly how the Holocaust, as well as the Nazi German policy of mass murder and forced labour took place. The collections at the site preserve the evidence of those who were premeditatedly murdered, as well as presenting the systematic mechanism by which this was done. The personal items in the collections are testimony to the lives of the victims before they were brought to the extermination camps, as well as to the cynical use of their possessions and remains. The site and its landscape have high levels of authenticity and integrity since the original evidence has been carefully conserved without any unnecessary restoration.
Although the Germans destroyed parts of the camps before abandoning them in 1945, much of Auschwitz I and Auschwitz II (Birkenau) remained intact and were later converted into a museum and memorial. The site has been threatened by increased industrial activity in Oświęcim. In 1996, however, the Polish government joined with other organizations in a large-scale effort to ensure its preservation. Originally named Auschwitz Concentration Camp, the memorial was designated a UNESCO World Heritage site in 1979. It was renamed “Auschwitz-Birkenau. The Nazi German Concentration and Extermination Camp (1940–1945)” in 2007.
The term "National Socialism" arose out of attempts to create a nationalist redefinition of "socialism", as an alternative to both international socialism and free market capitalism. Nazism rejected the Marxist concept of class conflict, opposed cosmopolitan internationalism, and sought to convince all parts of the new German society to subordinate their personal interests to the "common good", accepting political interests as the main priority of economic organization.[4]
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.
The hair of 12 year-old Lili had not been cut since her early childhood. When she and her family were forced to leave their home in Târgu-Mureş and move to the ghetto, Lili’s mother, Rivka, knew she would not be able to care properly for her daughter’s hair in the ghetto. Chopping off Lili’s two long, beautiful braids, she promised that they would be given to the neighbors for safekeeping.Within six weeks, Lili and her mother were murdered at Auschwitz.

Joseph Goebbels, who would later go on to become the Nazi Propaganda Minister, was strongly opposed to both capitalism and communism, viewing them as the "two great pillars of materialism" that were "part of the international Jewish conspiracy for world domination."[266] Nevertheless, he wrote in his diary in 1925 that if he were forced to choose between them, "in the final analysis", "it would be better for us to go down with Bolshevism than live in eternal slavery under capitalism".[267] He also linked his anti-Semitism to his anti-capitalism, stating in a 1929 pamphlet that "we see, in the Hebrews, the incarnation of capitalism, the misuse of the nation's goods."[166]

The Frank family was transported to Westerbork, a transit camp in the Netherlands, and from there to Auschwitz, in German-occupied Poland, on September 3, 1944, on the last transport to leave Westerbork for Auschwitz. Anne and Margot were transferred to Bergen-Belsen the following month. Anne’s mother died in early January, just before the evacuation of Auschwitz on January 18, 1945. It was established by the Dutch government that both Anne and Margot died in a typhus epidemic in March 1945, only weeks before the liberation of Bergen-Belsen, but scholars in 2015 revealed new research, including analysis of archival data and first-person accounts, indicating that the sisters might have perished in February 1945. Otto Frank was found hospitalized at Auschwitz when it was liberated by Soviet troops on January 27, 1945.
Very heavy strategic bombing by the Allies targeted refineries producing synthetic oil and gasoline, as well as the German transportation system, especially rail yards and canals.[287] The armaments industry began to break down by September 1944. By November, fuel coal was no longer reaching its destinations and the production of new armaments was no longer possible.[288] Overy argues that the bombing strained the German war economy and forced it to divert up to one-fourth of its manpower and industry into anti-aircraft resources, which very likely shortened the war.[289]
Early in the Nazi regime of Adolf Hitler, Anne’s father, Otto Frank (1889–1980), a German businessman, took his wife and two daughters to live in Amsterdam. In 1941, after German forces occupied the Netherlands, Anne was compelled to transfer from a public school to a Jewish one. On June 12, 1942, she received a red-and-white plaid diary for her 13th birthday. That day she began writing in the book: “I hope I will be able to confide everything to you, as I have never been able to confide in anyone, and I hope you will be a great source of comfort and support.”
Arthur Moeller van den Bruck was initially the dominant figure of the Conservative Revolutionaries influenced Nazism.[118] He rejected reactionary conservatism while proposing a new state that he coined the "Third Reich", which would unite all classes under authoritarian rule.[119] Van den Bruck advocated a combination of the nationalism of the right and the socialism of the left.[120]
The Nazis argued that free market capitalism damages nations due to international finance and the worldwide economic dominance of disloyal big business, which they considered to be the product of Jewish influences.[246] Nazi propaganda posters in working class districts emphasised anti-capitalism, such as one that said: "The maintenance of a rotten industrial system has nothing to do with nationalism. I can love Germany and hate capitalism".[261]

The concentration camps increasingly became sites where the SS authorities could kill targeted groups of real or perceived enemies of Nazi Germany. They also came to serve as holding centers for a rapidly growing pool of forced laborers used for SS construction projects, SS-commissioned extractive industrial sites, and, by 1942, the production of armaments, weapons, and related goods for the German war effort.
POW camps (Kriegsgefangenen-Mannschafts-Stammlager / Stalag) a.k.a. Main Camps for Enlisted Prisoners of War: concentration camps where enlisted prisoners-of-war were held after capture. The inmates were usually assigned soon to nearby labor camps, (Arbeitskommandos), i.e. the Work Details. POW officers had their own camps (Offizierslager' / Oflag). Stalags were for Army prisoners, but specialized camps (Marinelager / Marlag ("Navy camps") and Marineinterniertenlager / Milag ("Merchant Marine Internment Camps")) existed for the other services. Kriegsgefangenen-Mannschafts-Stammlager Luftwaffe / Stalag Luft ("Air Forces Camps") were the only camps that detained both officers and non-commissioned personnel together.
Auschwitz Birkenau was the largest of the concentration camp complexes created by the Nazi German regime and was the one which combined extermination with forced labour. At the centre of a huge landscape of human exploitation and suffering, the remains of the two camps of Auschwitz I and Auschwitz II-Birkenau were inscribed on the World Heritage List as evidence of this inhumane, cruel and methodical effort to deny human dignity to groups considered inferior, leading to their systematic murder. The camps are a vivid testimony to the murderous nature of the anti-Semitic and racist Nazi policy that brought about the annihilation of over one million people in the crematoria, 90% of whom were Jews.
In 1999, Time named Anne Frank among the heroes and icons of the 20th century on their list The Most Important People of the Century, stating: "With a diary kept in a secret attic, she braved the Nazis and lent a searing voice to the fight for human dignity".[91] Philip Roth called her the "lost little daughter" of Franz Kafka.[116] Madame Tussauds wax museum unveiled an exhibit featuring a likeness of Anne Frank in 2012.[117] Asteroid 5535 Annefrank was named in her honour in 1995, after having been discovered in 1942.[118]
From 1921 to 1922, Hitler evoked rhetoric of both the achievement of Lebensraum involving the acceptance of a territorially reduced Russia as well as supporting Russian nationals in overthrowing the Bolshevik government and establishing a new Russian government.[131] Hitler's attitudes changed by the end of 1922, in which he then supported an alliance of Germany with Britain to destroy Russia.[131] Hitler later declared how far he intended to expand Germany into Russia:
In 1958, at a performance of The Diary of Anne Frank in Vienna, Simon Wiesenthal was challenged by a group of protesters who asserted that Anne Frank had never existed, and who challenged Wiesenthal to prove her existence by finding the man who had arrested her. Wiesenthal indeed began searching for Karl Silberbauer and found him in 1963. When interviewed, Silberbauer admitted his role, and identified Anne Frank from a photograph as one of the people arrested. Silberbauer provided a full account of events, even recalling emptying a briefcase full of papers onto the floor. His statement corroborated the version of events that had previously been presented by witnesses such as Otto Frank.[95]

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.

Nazism attempted to reconcile conservative, nationalist ideology with a socially radical doctrine. In so doing, it became a profoundly revolutionary movement—albeit a largely negative one. Rejecting rationalism, liberalism, democracy, the rule of law, human rights, and all movements of international cooperation and peace, it stressed instinct, the subordination of the individual to the state, and the necessity of blind and unswerving obedience to leaders appointed from above. It also emphasized the inequality of men and races and the right of the strong to rule the weak; sought to purge or suppress competing political, religious, and social institutions; advanced an ethic of hardness and ferocity; and partly destroyed class distinctions by drawing into the movement misfits and failures from all social classes. Although socialism was traditionally an internationalist creed, the radical wing of Nazism knew that a mass base existed for policies that were simultaneously anticapitalist and nationalist. However, after Hitler secured power, this radical strain was eliminated.
Nevertheless, the Nazi Party's voter base consisted mainly of farmers and the middle class, including groups such as Weimar government officials, school teachers, doctors, clerks, self-employed businessmen, salesmen, retired officers, engineers, and students.[176] Their demands included lower taxes, higher prices for food, restrictions on department stores and consumer co-operatives, and reductions in social services and wages.[177] The need to maintain the support of these groups made it difficult for the Nazis to appeal to the working class, since the working class often had opposite demands.[177]
As far as we could see, there was no possibility in camp for any religious services. Sundays are workdays for the inmates. Among the Jewish prisoners the rabbis were treated especially badly. Officially the fight against religious affiliations is not admitted, but as a matter of fact National Socialism is no less antireligious than Bolshevism, with the only difference that it has not yet developed quite so far in the amalgamation of political and religious ideologies.
From the end of March 1942, Jewish transports from Nazi-ruled countries flowed into Auschwitz. Jews from Slovakia and France were deported there first, followed by Dutch Jews from July 1942, and from August, Jews from Belgium and Yugoslavia. Between October 1942 and October 1944, over 46 000 prisoners were deported from Terezín to Auschwitz. Some of them were put in the „Terezín family camp“ for a temporary period. Throughout 1943, transports were sent to Auschwitz from Germany and other countries in the Nazi sphere of power. The victims of the last great wave of deportations to Auschwitz were the Jews of Hungary, who were deported between May and July 1944.
Of the Jews sent to Bergen-Belsen, very few were set free. One group of 222 Jews reached Palestine after leaving Bergen-Belsen on 10 July 1944. The second group left the camp in two parts – in August and December 1945, the Kasztner transport was sent to Switzerland. Finally, on 25 January 1945, 136 Jews with South American passports reached Switzerland.

Auschwitz inmates began working at the plant, known as Buna Werke and IG Auschwitz, in April 1941, and demolishing houses in Monowitz to make way for it. By May, because of a shortage of trucks, several hundred of them were rising at 3 am to walk there twice a day from Auschwitz I.[53] Anticipating that a long line of exhausted inmates walking through the town of Oświęcim might harm German-Polish relations, the inmates were told to shave daily, make sure they were clean, and sing as they walked. From late July they were taken there by train on freight wagons.[54] Because of the difficulty of moving them, including during the winter, IG Farben decided to build a camp at the plant. The first inmates moved there on 30 October 1942.[55] Known as KL Auschwitz III-Aussenlager (Auschwitz III-subcamps), and later as Monowitz concentration camp,[56] it was the first concentration camp to be financed and built by private industry.[57]

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.
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]

Goods and raw materials were also taken. In France, an estimated 9,000,000 tonnes (8,900,000 long tons; 9,900,000 short tons) of cereals were seized during the course of the war, including 75 percent of its oats. In addition, 80 percent of the country's oil and 74 percent of its steel production were taken. The valuation of this loot is estimated to be 184.5 billion francs. In Poland, Nazi plunder of raw materials began even before the German invasion had concluded.[296]
Upon being appointed Chancellor in 1933, Hitler promised measures to increase employment, protect the German currency, and promote recovery from the Great Depression. These included an agrarian settlement program, labor service, and a guarantee to maintain health care and pensions.[220] But above all, his priority was rearmament, and the buildup of the German military in preparation for an eventual war to conquer Lebensraum in the East.[221] Thus, at the beginning of his rule, Hitler said that “the future of Germany depends exclusively and only on the reconstruction of the Wehrmacht. All other tasks must cede precedence to the task of rearmament.”[221] This policy was implemented immediately, with military expenditures quickly growing far larger than the civilian work-creation programs. As early as June 1933, military spending for the year was budgeted to be three times larger than the spending on all civilian work-creation measures in 1932 and 1933 combined.[222] Nazi Germany increased its military spending faster than any other state in peacetime, with the share of military spending rising from 1 percent to 10 percent of national income in the first two years of the regime alone.[223] Eventually, by 1944, it reached as high as 75 percent.[224]
The two largest groups of prisoners in the camps, both numbering in the millions, were the Polish Jews and the Soviet prisoners of war (POWs) held without trial or judicial process. There were also large numbers of Romani people, ethnic Poles, Serbs, political prisoners, homosexuals, people with disabilities, Jehovah's Witnesses, Catholic clergy, Eastern European intellectuals and others (including common criminals, as the Nazis declared). In addition, a small number of Western Allied aviators were sent to concentration camps as punishment for spying.[28] Western Allied POWs who were Jews, or who were suspected of being Jews by the Nazis, were usually sent to ordinary POW camps; however, a small number of them were sent to concentration camps because of antisemitic policies.[29]
