Those deported to Auschwitz arrived at the nearby train station and were marched or trucked to the main camp where they were registered, tattooed, undressed, deloused, had their body hair shaven off, showered while their clothes were disinfected with Zyklon-B gas, and entered the camp under the infamous gateway inscribed 'Arbeit Macht Frei' ("Labor make you free")
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. 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, while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe and that many of these camps were run for a limited amount of time before they were closed. 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.
But individual deaths, by sickness or violence, were not enough to keep the number of prisoners within manageable limits. Accordingly, in early 1941 Himmler decided to begin the mass murder of prisoners in gas chambers, building on a program that the Nazis had developed earlier for euthanizing the disabled. Here, again, the camps’ sinister combination of bureaucratic rationalism and anarchic violence was on display. During the following months, teams of S.S. doctors visited the major camps in turn, inspecting prisoners in order to select the “infirm” for gassing. Everything was done with an appearance of medical rigor. The doctors filled out a form for each inmate, with headings for “Diagnosis” and “Incurable Physical Ailments.” But it was all mere theatre. Helm’s description of the visit of Dr. Friedrich Mennecke to Ravensbrück, in November, 1941, shows that inspections of prisoners—whom he referred to in letters home as “forms” or “portions”—were cursory at best, with the victims parading naked in front of the doctors at a distance of twenty feet. (Jewish prisoners were automatically “selected,” without an examination.) In one letter, Mennecke brags of having disposed of fifty-six “forms” before noon. Those selected were taken to an undisclosed location for gassing; their fate became clear to the remaining Ravensbrück prisoners when the dead women’s clothes and personal effects arrived back at the camp by truck.
Hitler's conception of the Aryan Herrenvolk ("Aryan master race") excluded the vast majority of Slavs from central and eastern Europe (i.e. Poles, Russians, Ukrainians, etc.). They were regarded as a race of men not inclined to a higher form of civilization, which was under an instinctive force that reverted them back to nature. The Nazis also regarded the Slavs as having dangerous Jewish and Asiatic, meaning Mongol, influences. Because of this, the Nazis declared Slavs to be Untermenschen ("subhumans"). Nazi anthropologists attempted to scientifically prove the historical admixture of the Slavs who lived further East and leading Nazi racial theorist Hans Günther regarded the Slavs as being primarily Nordic centuries ago but he believed that they had mixed with non-Nordic types over time. Exceptions were made for a small percentage of Slavs who the Nazis saw as descended from German settlers and therefore fit to be Germanised and considered part of the Aryan master race. Hitler described Slavs as "a mass of born slaves who feel the need for a master". The Nazi notion of Slavs as inferior served as a legitimization of their desire to create Lebensraum for Germans and other Germanic people in eastern Europe, where millions of Germans and other Germanic settlers would be moved into once those territories were conquered, while the original Slavic inhabitants were to be annihilated, removed or enslaved. Nazi Germany's policy changed towards Slavs in response to military manpower shortages, forced it to allow Slavs to serve in its armed forces within the occupied territories in spite of the fact that they were considered "subhuman".
The majority of scholars identify Nazism in both theory and practice as a form of far-right politics. Far-right themes in Nazism include the argument that superior people have a right to dominate other people and purge society of supposed inferior elements. Adolf Hitler and other proponents denied that Nazism was either left-wing or right-wing, instead they officially portrayed Nazism as a syncretic movement. In Mein Kampf, Hitler directly attacked both left-wing and right-wing politics in Germany, saying:
There is a serious anachronism at work: the coverage that speaks to Schneidermann on an emotional level now was largely ineffective at the time it was printed. He muses that the journalists in the thirties needed to invent a new language, but he doesn’t quite define what that language should have looked like—dry facts didn’t allow an audience truly to comprehend the incomprehensible, but irony didn’t work, either, and neither did outcry. He faults the news outlets, above all, for not publishing vivid portraits of the victims. “Facts. Raw facts,” Schneidermann writes of press descriptions of Jewish refugees in 1939. “We can’t accuse the New York Times of having avoided the raw facts. Except that the raw facts don’t suffice. They never suffice. In order for a piece of news to touch consciences and hearts, there must be emotion running through it.”
When we were in Gusen penal camp, my father, who was 50, one day just gave up and said he couldn’t continue. From that moment I was totally alone. In February 1945 they moved us to Gunskirchen, Upper Austria. It was here that I witnessed starving people eating human flesh. We were liberated by Americans and Canadians in Gunskirchen. The Germans had simply left the camp, and with an absence of drama we just walked through the gates. The first thing I did was to knock on a local resident’s door and ask for permission to take a shower. Somehow, I managed to meet up with my brothers, David and Shuli. We had no desire to return to Dej, to the people who had betrayed us.
Between 1933 and the fall of Nazi Germany in 1945, more than 3.5 million Germans were forced to spend time in concentration camps and prisons for political reasons, and approximately 77,000 Germans were executed for one or another form of resistance by Special Courts, courts-martial, and the civil justice system. Many of these Germans had served in government, the military, or in civil positions, which enabled them to engage in subversion and conspiracy against the Nazis.
