However, this regulation was soon waived and there is ample evidence that full Nazi Party members served in the Wehrmacht in particular after the outbreak of World War II. The Wehrmacht Reserves also saw a high number of senior Nazis enlisting, with Reinhard Heydrich and Fritz Todt joining the Luftwaffe, as well as Karl Hanke who served in the army.
All of the extermination camps were thoroughly organised and resembled industrial plants to an alarming degree. However, only Auschwitz-Birkenau, with its advanced gassing facilities and crematoria, was marked by high technology. In crematoria I and II there were elevators from the gas chambers underground, where the Jews were murdered, to the crematoria, where the bodies were burned.

In Germany, the belief that Jews were economically exploiting Germans became prominent due to the ascendancy of many wealthy Jews into prominent positions upon the unification of Germany in 1871.[85] From 1871 to the early 20th century, German Jews were overrepresented in Germany's upper and middle classes while they were underrepresented in Germany's lower classes, particularly in the fields of agricultural and industrial labour.[86] German Jewish financiers and bankers played a key role in fostering Germany's economic growth from 1871 to 1913 and they benefited enormously from this boom. In 1908, amongst the twenty-nine wealthiest German families with aggregate fortunes of up to 55 million marks at the time, five were Jewish and the Rothschilds were the second wealthiest German family.[87] The predominance of Jews in Germany's banking, commerce and industry sectors during this time period was very high, even though Jews were estimated to account for only 1% of the population of Germany.[85] The overrepresentation of Jews in these areas fueled resentment among non-Jewish Germans during periods of economic crisis.[86] The 1873 stock market crash and the ensuing depression resulted in a spate of attacks on alleged Jewish economic dominance in Germany and antisemitism increased.[86] During this time period, in the 1870s, German Völkisch nationalism began to adopt antisemitic and racist themes and it was also adopted by a number of radical right political movements.[88]
Sessions’s characterization falls into a nether region between truth and falsehood. Perhaps his is the best comment to begin with precisely because it is a half-truth. Yes, after 1941, concentration camps held Jews to prevent them from leaving Germany — but also to consolidate them for extermination. However, for more than eight years earlier, the camps generally were used for the opposite purpose: to force Jews to emigrate from Germany by making life intolerable, in part by separating men from their families. This is precisely the kind of important historical nuance lost in the hysteria surrounding Trump’s callous immigration policy. There are valuable comparisons to be made, but they must be historically informed.

The exposure of the sick, weak, deformed children, in short, their destruction, was more decent and in truth a thousand times more humane than the wretched insanity of our day which preserves the most pathological subject.
Hitler's talent as an orator and his ability to draw new members, combined with his characteristic ruthlessness, soon made him the dominant figure. However, while Hitler and Eckart were on a fundraising trip to Berlin in June 1921, a mutiny broke out within the party in Munich. Members of its executive committee wanted to merge with the rival German Socialist Party (DSP).[60] Upon returning to Munich on 11 July, Hitler angrily tendered his resignation. The committee members realised that his resignation would mean the end of the party.[61] Hitler announced he would rejoin on condition that he would replace Drexler as party chairman, and that the party headquarters would remain in Munich.[62] The committee agreed, and he rejoined the party on 26 July as member 3,680. Hitler continued to face some opposition within the NSDAP, as his opponents had Hermann Esser expelled from the party and they printed 3,000 copies of a pamphlet attacking Hitler as a traitor to the party.[62] In the following days, Hitler spoke to several packed houses and defended himself and Esser to thunderous applause.[63]
That same day, Gestapo official SS Sergeant Karl Silberbauer and two Dutch police collaborators arrested the Franks. The Gestapo sent them to Westerbork on Aug. 8. One month later, in September 1944, SS and police authorities placed the Franks, and the four others hiding with them, on a train transport from Westerbork to the Auschwitz camp complex in German-occupied Poland. Selected for labor due to their youth, Anne and her sister, Margot were transferred to the Bergen-Belsen concentration camp near Celle, in northern Germany, in late October 1944.

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.

^ In his testimony, according to Polish historian Aleksander Lasik, "Höss neither protected anyone nor evaded his own responsibility. His stance came as a surprise to many, especially those who viewed him as a bloodthirsty beast. Instead, he viewed his crimes in terms of the technical obstacles and challenges with which he had to cope. Höss stated that he led the killings in Auschwitz on express orders of Reichsführer Himmler."[265]
After conquering Poland, Hitler focused on defeating Britain and France. As the war expanded, the Nazi Party formed alliances with Japan and Italy in the Tripartite Pact of 1940, and honored its 1939 Nazi-Soviet Nonaggression Pact with the Soviet Union until 1941, when Germany launched a massive blitzkrieg invasion of the Soviet Union. In the brutal fighting that followed, Nazi troops tried to realize the long-held goal of crushing the world’s major communist power. After the United States entered the war in 1941, Germany found itself fighting in North Africa, Italy, France, the Balkans and in a counterattacking Soviet Union. At the beginning of the war, Hitler and his Nazi Party were fighting to dominate Europe; five years later they were fighting to exist.
This complex incorporated 45 forced labor sub-camps. The name Buna was based on the Buna synthetic rubber factory on site, owned by I.G. Farben, Germany’s largest chemical company. Most workers at this and other German-owned factories were Jewish inmates. The labor would push inmates to the point of total exhaustion, at which time new laborers replaced them.
After September 1939, with the beginning of the Second World War, concentration camps became places where millions of ordinary people were enslaved as part of the war effort, often starved, tortured and killed.[21] During the war, new Nazi concentration camps for "undesirables" spread throughout the continent. According to statistics by the German Ministry of Justice, about 1,200 camps and subcamps were run in countries occupied by Nazi Germany,[22] while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe[23][24] and that many of these camps were run for a limited amount of time before they were closed.[23] Camps were being created near the centers of dense populations, often focusing on areas with large communities of Jews, Polish intelligentsia, Communists or Romani. Since millions of Jews lived in pre-war Poland, most camps were located in the area of the General Government in occupied Poland, for logistical reasons. The location also allowed the Nazis to quickly remove the German Jews from within Germany proper.
