Nazi plunder included private and public art collections, artefacts, precious metals, books, and personal possessions. Hitler and Göring in particular were interested in acquiring looted art treasures from occupied Europe,[291] the former planning to use the stolen art to fill the galleries of the planned Führermuseum (Leader's Museum),[292] and the latter for his personal collection. Göring, having stripped almost all of occupied Poland of its artworks within six months of Germany's invasion, ultimately grew a collection valued at over 50 million Reichsmarks.[291] In 1940, the Reichsleiter Rosenberg Taskforce was established to loot artwork and cultural material from public and private collections, libraries, and museums throughout Europe. France saw the greatest extent of Nazi plunder. Some 26,000 railroad cars of art treasures, furniture, and other looted items were sent to Germany from France.[293] By January 1941, Rosenberg estimated the looted treasures from France to be valued at over one billion Reichsmarks.[294] In addition, soldiers looted or purchased goods such as produce and clothing—items, which were becoming harder to obtain in Germany—for shipment home.[295]

When I returned this past autumn, the hair was a barely differentiated mass of gray, more like wool than human locks. Only the occasional braid signaled the remnants of something unprecedented and awful—the site where the Third Reich perpetrated the largest mass murder in human history. At least 1.1 million people were killed here, most within hours of their arrival.
Auschwitz-Birkenau became the killing centre where the largest numbers of European Jews were killed during the Holocaust. After an experimental gassing there in September 1941 of 850 malnourished and ill prisoners, mass murder became a daily routine. By mid 1942, mass gassing of Jews using Zyklon-B began at Auschwitz, where extermination was conducted on an industrial scale with some estimates running as high as three million persons eventually killed through gassing, starvation, disease, shooting, and burning ...

Kaiser Wilhelm II, who was pressured to abdicate the throne and flee into exile amidst an attempted communist revolution in Germany, initially supported the Nazi Party. His four sons, including Prince Eitel Friedrich and Prince Oskar, became members of the Nazi Party in hopes that in exchange for their support, the Nazis would permit the restoration of the monarchy.[36]

On 22 June 1941, contravening the Molotov–Ribbentrop Pact, 5.5 million Axis troops attacked the Soviet Union. In addition to Hitler's stated purpose of acquiring Lebensraum, this large-scale offensive—codenamed Operation Barbarossa—was intended to destroy the Soviet Union and seize its natural resources for subsequent aggression against the Western powers.[115] The reaction among Germans was one of surprise and trepidation as many were concerned about how much longer the war would continue or suspected that Germany could not win a war fought on two fronts.[116]

The concentration camps make sense only if they are understood as products not of reason but of ideology, which is to say, of fantasy. Nazism taught the Germans to see themselves as a beleaguered nation, constantly set upon by enemies external and internal. Metaphors of infection and disease, of betrayal and stabs in the back, were central to Nazi discourse. The concentration camp became the place where those metaphorical evils could be rendered concrete and visible. Here, behind barbed wire, were the traitors, Bolsheviks, parasites, and Jews who were intent on destroying the Fatherland.

Poles were viewed by Nazis as subhuman non-Aryans, and during the German occupation of Poland 2.7 million ethnic Poles were killed.[342] Polish civilians were subject to forced labour in German industry, internment, wholesale expulsions to make way for German colonists, and mass executions. The German authorities engaged in a systematic effort to destroy Polish culture and national identity. During operation AB-Aktion, many university professors and members of the Polish intelligentsia were arrested, transported to concentration camps, or executed. During the war, Poland lost an estimated 39 to 45 percent of its physicians and dentists, 26 to 57 percent of its lawyers, 15 to 30 percent of its teachers, 30 to 40 percent of its scientists and university professors, and 18 to 28 percent of its clergy.[343]

The Nazis took things further, one step at the time. Jews had to start wearing a Star of David on their clothes and there were rumours that all Jews would have to leave the Netherlands. When Margot received a call-up to report for a so-called ‘labour camp’ in Nazi Germany on 5 July 1942, her parents were suspicious. They did not believe the call-up was about work and decided to go into hiding the next day in order to escape persecution.  
The complex, which divided into three main areas, was established by the Nazi’s in 1940 and was in use until its Allied liberation in 1945. Historians and analysts estimate the number of people murdered at Auschwitz somewhere between 2.1 million to 4 million, of whom the vast majority were Jews. The majority of prisoners held at Auschwitz were killed in the various gas chambers though many died from starvation, forced labor, disease, shooting squads, and heinous medical experiments.
Long before the Nazis took power, concentration camps had featured in their imagination. Wachsmann finds Hitler threatening to put Jews in camps as early as 1921. But there were no detailed plans for building such camps when Hitler was named Chancellor of Germany, in January, 1933. A few weeks later, on February 27th, he seized on the burning of the Reichstag—by Communists, he alleged—to launch a full-scale crackdown on his political opponents. The next day, he implemented a decree, “For the Protection of People and State,” that authorized the government to place just about anyone in “protective custody,” a euphemism for indefinite detention. (Euphemism, too, was to be a durable feature of the K.L. universe: the killing of prisoners was referred to as Sonderbehandlung, “special treatment.”)
^ Hitler stated: "Today our left-wing politicians in particular are constantly insisting that their craven-hearted and obsequious foreign policy necessarily results from the disarmament of Germany, whereas the truth is that this is the policy of traitors […] But the politicians of the Right deserve exactly the same reproach. It was through their miserable cowardice that those ruffians of Jews who came into power in 1918 were able to rob the nation of its arms." Adolf Hitler. Mein Kampf.

On 26 June 1933, Himmler appointed Theodor Eicke commandant of Dachau, who in 1934 was also appointed the first Inspector of Concentration Camps (CCI). In addition, the remaining SA-run camps were taken over by the SS.[14][15][16] Dachau served as both a prototype and a model for the other Nazi concentration camps. Almost every community in Germany had members who were taken there. The newspapers continuously reported on "the removal of the enemies of the Reich to concentration camps" making the general population more aware of their presence. There were jingles warning as early as 1935: "Dear God, make me dumb, that I may not come to Dachau."[17]
