“Responsibility is extremely direct in face-to-face shootings,” Dwork says. “In gassing and cremation, each person is given only a small part.” Eventually, Germans took part only by tossing the cyanide pellets into the gas chambers. Everything else—herding prisoners into the chambers, ripping out gold fillings and loading corpses into the crematoria—was handled by groups of prisoners, known as Sonderkommandos.
When the Nazis came to power in Germany, they quickly moved to suppress all real and potential opposition. The general public was intimidated by the arbitrary psychological terror that was used by the special courts (Sondergerichte).[11] Especially during the first years of their existence when these courts "had a strong deterrent effect" against any form of political protest.[12]
Nazi comes from the German word for National Socialist (Nationalsozialistische). A Nazi is a person who believes in the ideologies and practices of the National Socialist German Workers' Party (Nationalsozialistische Deutsche Arbeiterpartei), abbreviated NSDAP, a racialist (belief that one race is superior to others), totalitarian (government having absolute and centralized control) political party in Germany between 1919 and 1945. It was known as the German Workers' Party (DAP) before the name was changed in 1920.
Auschwitz is enshrined in history in part because, as a work camp, there were survivors. Anita Lasker-Wallfisch was a 14-year-old Jewish cello student living in the German city of Breslau (now Wroclaw in Poland) when the war broke out. Two years later, she and her sister Renate were sent to work in a nearby paper factory. In 1942, after the Germans deported her parents to a death camp, the sisters doctored their identity papers and tried to escape.
We were sent to the Radom ghetto, where I spent the first years of the war working for the Jewish committee. But when they started taking the ghetto leaders to Auschwitz, I quickly changed jobs and began working in a munitions factory instead, hoping that if I kept my head down, I might be OK. But after moving from one factory to another, I too was deported to Auschwitz when the ghetto was liquidated in 1942. I was separated from my parents and three sisters, all of whom were taken to Treblinka.
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.
Another method was the use of gassing trucks. In Chemno gassing trucks were used, where Jews, after being driven into the trucks, were suffocated by the exhaust fumes that were led into them in the truck. A third method was mass shooting of Jews and other groups (Soviet POW’s, Poles, etc.). In Majdanek, on 3-4 November 1943, between 17,000 and 18,000 Jews were killed in one day as part of a mass shooting. The event was called Erntefest (‘harvest feast’) and included similar actions all around the Lublin District. More than 40,000 Jews died as a result.

During the 1920s, Hitler urged disparate Nazi factions to unite in opposition to Jewish Bolshevism.[251] Hitler asserted that the "three vices" of "Jewish Marxism" were democracy, pacifism and internationalism.[252] The Communist movement, the trade unions, the Social Democratic Party and the left-wing press were all considered to be Jewish-controlled and part of the "international Jewish conspiracy" to weaken the German nation by promoting internal disunity through class struggle.[53] The Nazis also believed that the Jews had instigated the Bolshevik revolution in Russia and that Communists had stabbed Germany in the back and caused it to lose the First World War.[253] They further argued that modern cultural trends of the 1920s (such as jazz music and cubist art) represented "cultural Bolshevism" and were part of a political assault aimed at the spiritual degeneration of the German Volk.[253] Joseph Goebbels published a pamphlet titled The Nazi-Sozi which gave brief points of how National Socialism differed from Marxism.[254] In 1930, Hitler said: "Our adopted term 'Socialist' has nothing to do with Marxist Socialism. Marxism is anti-property; true Socialism is not".[255]
The Nazis, the far-right monarchists, the reactionary German National People's Party (DNVP) and others, such as monarchist officers in the German Army and several prominent industrialists, formed an alliance in opposition to the Weimar Republic on 11 October 1931 in Bad Harzburg, officially known as the "National Front", but commonly referred to as the Harzburg Front.[30] The Nazis stated that the alliance was purely tactical and they continued to have differences with the DNVP. The Nazis described the DNVP as a bourgeois party and they called themselves an anti-bourgeois party.[30] After the elections of July 1932, the alliance broke down when the DNVP lost many of its seats in the Reichstag. The Nazis denounced them as "an insignificant heap of reactionaries".[31] The DNVP responded by denouncing the Nazis for their socialism, their street violence and the "economic experiments" that would take place if the Nazis ever rose to power.[32] But amidst an inconclusive political situation in which conservative politicians Franz von Papen and Kurt von Schleicher were unable to form stable governments without the Nazis, Papen proposed to President Hindenburg to appoint Hitler as Chancellor at the head of a government formed primarily of conservatives, with only three Nazi ministers.[33][34] Hindenburg did so, and contrary to the expectations of Papen and the DNVP, Hitler was soon able to establish a Nazi one-party dictatorship.[35]
The crisis led to war preparations by Britain, Czechoslovakia, and France (Czechoslovakia's ally). Attempting to avoid war, British Prime Minister Neville Chamberlain arranged a series of meetings, the result of which was the Munich Agreement, signed on 29 September 1938. The Czechoslovak government was forced to accept the Sudetenland's annexation into Germany. Chamberlain was greeted with cheers when he landed in London, saying the agreement brought "peace for our time".[70] The agreement lasted six months before Hitler seized the rest of Czech territory in March 1939.[71]
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]
