Nazi eugenics were Nazi Germany's racially-based social policies that placed the improvement of the race through eugenics at the center of their concerns and targeted those humans they identified as "life unworthy of life" (Lebensunwertes Leben), including but not limited to the criminal, degenerate, dissident, feeble-minded, homosexual, idle, insane, religious, and weak, for elimination from the chain of heredity. More than 400,000 people were sterilized against their will. Adolf Hitler (Führer and Chancellor of Germany unitl 1945) believed the nation had become weak, corrupted by the infusion of degenerate elements into its bloodstream which had to be removed as quickly as possible. He also believed that the strong and the racially pure had to be encouraged to have more children, and the weak and the racially impure had to be neutralized by one means or another.
In October 1944, the 'Sonderkommando' crew crematoria IV revolted and destroyed the crematories. In November Himmler ordered gassings to stop, and a 'cleanup' operation was inaugurated to conceal traces of the mass murder. In January 1945, the Germans evacuated 58,000 prisoners who could walk. They left behind in the main camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long.
At universities, appointments to top posts were the subject of power struggles between the education ministry, the university boards, and the National Socialist German Students' League.[361] In spite of pressure from the League and various government ministries, most university professors did not make changes to their lectures or syllabus during the Nazi period.[362] This was especially true of universities located in predominantly Catholic regions.[363] Enrolment at German universities declined from 104,000 students in 1931 to 41,000 in 1939, but enrolment in medical schools rose sharply as Jewish doctors had been forced to leave the profession, so medical graduates had good job prospects.[364] From 1934, university students were required to attend frequent and time-consuming military training sessions run by the SA.[365] First-year students also had to serve six months in a labour camp for the Reich Labour Service; an additional ten weeks service were required of second-year students.[366]
Auschwitz II, located in the village of Birkenau, or Brzezinka, just outside OÅ›wiÄ™cim, was constructed in 1941 on the order of Heinrich Himmler (1900-45), commander of the “Schutzstaffel” (or Select Guard/Protection Squad, more commonly known as the SS), which operated all Nazi concentration camps and death camps. Birkenau, the biggest of the Auschwitz facilities, could hold some 90,000 prisoners. It also housed a group of bathhouses where countless people were gassed to death, and crematory ovens where bodies were burned. The majority of Auschwitz victims died at Birkenau.More than 40 smaller facilities, called subcamps, dotted the landscape and served as slave-labor camps. The largest of these subcamps, Monowitz, also known as Auschwitz III, began operating in 1942 and housed some 10,000 prisoners.
I worked out pretty quickly certain survival tricks. That if the guards called us to line up in front of the barracks, I should hide or sneak into another barracks. The safest place I could find to hide was in the yard near the bathrooms where all the dead bodies were brought and piled up … I would get on the pile, lie down next to the dead bodies and pretend I was one of them.
On 6 June 1944, American, British, and Canadian forces established a front in France with the D-Day landings in Normandy.[133] On 20 July 1944, Hitler survived an assassination attempt.[134] He ordered brutal reprisals, resulting in 7,000 arrests and the execution of more than 4,900 people.[135] The failed Ardennes Offensive (16 December 1944 – 25 January 1945) was the last major German offensive on the western front, and Soviet forces entered Germany on 27 January.[136] Hitler's refusal to admit defeat and his insistence that the war be fought to the last man led to unnecessary death and destruction in the war's closing months.[137] Through his Justice Minister Otto Georg Thierack, Hitler ordered that anyone who was not prepared to fight should be court-martialed, and thousands of people were put to death.[138] In many areas, people surrendered to the approaching Allies in spite of exhortations of local leaders to continue to fight. Hitler ordered the destruction of transport, bridges, industries, and other infrastructure—a scorched earth decree—but Armaments Minister Albert Speer prevented this order from being fully carried out.[137]

The irregular Swiss branch of the Nazi Party also established a number of Party Gaue in that country, most of them named after their regional capitals. These included Gau Basel-Solothurn, Gau Schaffhausen, Gau Luzern, Gau Bern and Gau Zürich.[111][112][113] The Gau Ostschweiz (East Switzerland) combined the territories of three cantons: St. Gallen, Thurgau and Appenzell.[114]

Influenced by the Völkisch movement, the regime was against cultural modernism and supported the development of an extensive military at the expense of intellectualism.[8][187] Creativity and art were stifled, except where they could serve as propaganda media.[188] The party used symbols such as the Blood Flag and rituals such as the Nazi Party rallies to foster unity and bolster the regime's popularity.[189]
Before beginning Jewish exterminations, though, the Nazi’s used the Soviet POWs at the Auschwitz camp in trials of the poison gas Zyklon-B, produced by the German company “Degesch” (Deutsche Gesellschaft zur Schädlingsbekämpfung), which was marked as the best way to kill many people at once. The POWs were gassed in underground cells in Block 11, the so called “Death Block,” and following these trials, one gas chamber was setup just outside the main camp and two temporary gas chambers were opened at Birkenau.
Generally speaking, Nazi theorists and politicians blamed Germany's previous economic failures on political causes like the influence of Marxism on the workforce, the sinister and exploitative machinations of what they called international Jewry and the vindictiveness of the western political leaders' war reparation demands. Instead of traditional economic incentives, the Nazis offered solutions of a political nature, such as the elimination of organised trade unions, rearmament (in contravention of the Versailles Treaty) and biological politics.[217] Various work programs designed to establish full-employment for the German population were instituted once the Nazis seized full national power. Hitler encouraged nationally supported projects like the construction of the Autobahn highway system, the introduction of an affordable people's car (Volkswagen) and later the Nazis bolstered the economy through the business and employment generated by military rearmament.[218] The Nazis benefited early in the regime's existence from the first post–Depression economic upswing, and this combined with their public works projects, job-procurement program and subsidised home repair program reduced unemployment by as much as 40 percent in one year. This development tempered the unfavourable psychological climate caused by the earlier economic crisis and encouraged Germans to march in step with the regime.[219]
The German army had invaded the Netherlands in May 1940, and very quickly had imposed their antisemitic policies. In late 1941 they decided that Westerbork was an ideal place in which to assemble the Jews of Holland before their deportation. The first Jews arrived at the camp on 14 July, and the first deportation to Auschwitz left the following day.
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]
