The gas chambers in the Auschwitz complex constituted the largest and most efficient extermination method employed by the Nazis. Four chambers were in use at Birkenau, each with the potential to kill 6,000 people daily. They were built to look like shower rooms in order to confuse the victims. New arrivals at Birkenau were told that they were being sent to work, but first needed to shower and be disinfected. They would be led into the shower-like chambers, where they were quickly gassed to death with the highly poisonous Zyklon B gas.
^ On 29 November 2006, State Secretary in the Federal Ministry of the Interior Christoph Bergner said the reason the statistics do not match is because Haar only includes people who were directly killed. The figure of 2 to 2.5 million also includes people who died of disease, hunger, cold, air raids and other causes. Koldehoff 2006. The German Red Cross still maintains that the death toll from the expulsions is 2.2 million. Kammerer & Kammerer 2005, p. 12.
As the government and military began to collapse within Germany, Nazi officials in both Germany and occupied Poland began to think about their endgame. In November 1944, Heinrich Himmler, head of the SS and one of the architects of the Holocaust, issued an abruptorder to destroy the gas chambers at Auschwitz-Birkenau, the largest of Auschwitz’s three main camps. Historians disagree on why he issued the command, which was in direct opposition to a previous order by Adolf Hitler to destroy the remaining Jews in Europe.

Following the camp's liberation, the Soviet government issued a statement, on 8 May 1945, that four million people had been killed on the site, a figure based on the capacity of the crematoria and later regarded as too high.[185] Höss told prosecutors at Nuremberg that at least 2,500,000 people had been murdered in Auschwitz by gassing and burning, and that another 500,000 had died of starvation and disease.[186] He testified that the figure of over two million had come from Eichmann.[187][d] In his memoirs, written in custody, he wrote that he regarded this figure as "far too high. Even Auschwitz had limits to its destructive possibilities."[189] Raul Hilberg's 1961 work, The Destruction of the European Jews, estimated that up to 1,000,000 Jews had died in Auschwitz.[190]

Even in the evening, when we had sunk wearily on our straw cots, we were not safe from the cruel whims of the S. S. men. If we didn't jump up quickly enough at their sudden appearance they made us practise jumping up and lying down until we were exhausted, or they had the entire ward line up outside the barracks in the cold and stand for half an hour or longer in the attitude of the 'Saxon Salute—that is, with hands folded behind the head. If an S.S. man entered the barracks in the daytime and was not seen at once by the inmate cleaning up and not saluted, then he might very well have the 'culprit' crawl in and out of the straw a dozen times for punishment. The guards were like mean children who torment animals.

The Franks had to be careful not be caught by the Germans. They covered all the windows with thick curtains. During the day they had to be extra quiet. They whispered when they talked and went barefoot so they could walk softly. At night, when the people working in the business below went home, they could relax a bit, but they still had to be very careful.
^ The escapees included 396 Polish men and 10 Polish women; 164 men from the Soviet Union (including 50 prisoners of war), and 15 women; 112 Jewish men and three Jewish women; 36 Romani/Sinti men and two women; 22 German men and nine women; 19 Czech men and four women; two Austrians; one Yugoslav woman and one man; and 15 other men and one woman.[217]
Radio became popular in Germany during the 1930s; over 70 percent of households owned a receiver by 1939, more than any other country. By July 1933, radio station staffs were purged of leftists and others deemed undesirable.[456] Propaganda and speeches were typical radio fare immediately after the seizure of power, but as time went on Goebbels insisted that more music be played so that listeners would not turn to foreign broadcasters for entertainment.[457]
As the Soviet Army advanced from the east, the Nazis transported prisoners away from the front and deep into Germany. Some prisoners were taken from the camps by train, but most were force-marched hundreds of miles, often in freezing weather and without proper clothing or shoes. Over the course of these death marches, which sometimes lasted weeks, tens of thousands of people died from cold or hunger, or were shot because they could not keep up.
Auschwitz-Birkenau was the largest Nazi extermination and concentration camp, located in the Polish town of Oswiecim, 37 miles west of Cracow. One sixth of all Jews murdered by the Nazis were gassed at Auschwitz. In April 1940 SS chief Heinrich Himmler ordered the establishment of a new concentration camp in Oswiecim, a town located within the portion of Poland that was annexed to Germany at the beginning of World War II. The first Polish political prisoners arrived in Auschwitz in June 1940, and by March 1941 there were 10,900 prisoners, the majority of whom were Polish. Auschwitz soon became known as the most brutal of the Nazi concentration camps.

Mendelian inheritance, or Mendelism, was supported by the Nazis, as well as by mainstream eugenicists of the time. The Mendelian theory of inheritance declared that genetic traits and attributes were passed from one generation to another.[104] Eugenicists used Mendelian inheritance theory to demonstrate the transfer of biological illness and impairments from parents to children, including mental disability, whereas others also utilised Mendelian theory to demonstrate the inheritance of social traits, with racialists claiming a racial nature behind certain general traits such as inventiveness or criminal behaviour.[105]

"Many times off-campus student actions, under the care of their parents and guardians, negatively impact our educational environment. We take our responsibility to students seriously when they are in our care and when their actions outside our care impact our learning environment," officials said, adding that the district does not "shy away from this responsibility."
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]

Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35.[5] Himmler expanded the role of the camps to hold so-called "racially undesirable elements", such as Jews, Gypsies/Romanis/Sintis, Serbs, Poles, disabled people, and criminals.[6][7][8] The number of people in the camps, which had fallen to 7,500, grew again to 21,000 by the start of World War II[9] and peaked at 715,000 in January 1945.[10]
