In effort to counter the strength and influence of spiritual resistance, Nazi security services monitored clergy very closely.[58]:141–2 Priests were frequently denounced, arrested and sent to concentration camps, often simply on the basis of being "suspected of activities hostile to the State" or that there was reason to "suppose that his dealings might harm society".[58]:142 Despite SS hostility to religious observance, the Vatican and German bishops successfully lobbied the regime to concentrate clergy at one camp and obtained permission to build a chapel, for the priests to live communally and for time to be allotted to them for the religious and intellectual activity. Priests Barracks at Dachau were established in Blocks 26, 28 and 30, though only temporarily. 26 became the international block and 28 was reserved for Poles – the most numerous group.[58]:145–6

The SS: The SS was a military-style group of Nazis, founded in 1925, who were like Hitler's personal bodyguards. They were in charge of overseeing the killing of people in the camps. Part of the SS called the Einsatzgruppen were put in charge of killing many people, before the extermination camps were opened to carry this out on a much greater scale. The SS also took control of intelligence, security and the police force.

The superior race was the "Aryans," the Germans. The word Aryan, "derived from the study of linguistics, which started in the eighteenth century and at some point determined that the Indo-Germanic (also known as Aryan) languages were superior in their structures, variety, and vocabulary to the Semitic languages that had evolved in the Near East. This judgment led to a certain conjecture about the character of the peoples who spoke these languages; the conclusion was that the 'Aryan' peoples were likewise superior to the 'Semitic' ones" (Leni Yahil, The Holocaust: The Fate of European Jewry, New York: Oxford University Press, 1990, p. 36).

On April 15, 1945, Bergen-Belsen was liberated by the Allied 21st Army Group, a combined British-Canadian unit. At the time of liberation, the camp had been without food or water for three to five days. As Matthew Nesbitt, a Canadian liberator, recounted, "…the first thing we had to do when we got to camp. Prior to even distributing the food. And that was to make sure we used the guards to separate the living from the dead, from the huts, because first of all, if we are going to save anybody, we had to know who was alive and who had to be buried…The only way you could do that was to go into each individual hut and shake whoever was on that little slab…if they didn't move, they were dead."
In the first few decades after the Holocaust, scholars argued that it was unique as a genocide in its reach and specificity.[476] This began to change in the 1980s during the West German Historikerstreit ("historians' dispute"), an attempt to re-position the Holocaust within German historiography. Ernst Nolte triggered the dispute in June 1986 with an article in the Frankfurter Allgemeine Zeitung: "Vergangenheit, die nicht vergehen will: Eine Rede, die geschrieben, aber nicht mehr gehalten werden konnte" ("The past that will not pass: A speech that could be written but not delivered"), in which he compared Auschwitz to the Gulag and suggested that the Holocaust was a response to Hitler's fear of the Soviet Union: "Was the Bolshevik murder of an entire class not the logical and factual prius of the 'racial murder' of National Socialism? ... Was the source of Auschwitz a past that would not go away?"[aa]

On 15 September 1935, the Reichstag passed the Reich Citizenship Law and the Law for the Protection of German Blood and German Honor, known as the Nuremberg Laws. The former said that only those of "German or kindred blood" could be citizens. Anyone with three or more Jewish grandparents was classified as a Jew.[107] The second law said: "Marriages between Jews and subjects of the state of German or related blood are forbidden." Sexual relationships between them were also criminalized; Jews were not allowed to employ German women under the age of 45 in their homes.[108] The laws referred to Jews but applied equally to the Roma and black Germans.[107]
After 1945 the name was applied to the displaced persons camp established nearby, but it is most commonly associated with the concentration camp. From 1941 to 1945, almost 20,000 Soviet prisoners of war and a further 50,000 inmates died there.[3] Overcrowding, lack of food and poor sanitary conditions caused outbreaks of typhus, tuberculosis, typhoid fever and dysentery, leading to the deaths of more than 35,000 people in the first few months of 1945, shortly before and after the liberation.
