Man blinded by continuous beatings  © The ideas and emotions that lay behind the Holocaust were not new, nor were they uniquely German. The Nazis were the heirs of a centuries-old tradition of Jew-hatred, rooted in religious rivalry and found in all European countries. When the Nazis came to carry out their genocidal programme, they found collaborators in all the countries they dominated, including governments that enjoyed considerable public support. Most people drew the line at mass murder, but relatively few could be found to oppose it actively or to extend help to the Jews.

("I maintain ... that the National Socialist killing of the Jews was unique in that never before had a state with the authority of its leader decided and announced that a specific group of humans, including the elderly, the women, the children and the infants, would be killed as quickly as possible, and then carried out this resolution using every possible means of state power.")[35]
The Memorial Site on the grounds of the former concentration camp was established in 1965 on the initiative of and in accordance with the plans of the surviving prisoners who had joined together to form the Comité International de Dachau. The Bavarian state government provided financial support. Between 1996 and 2003 a new exhibition on the history of the Dachau concentration camp was created, following the leitmotif of the "Path of the Prisoners".
We continued to sing, to laugh, to dream, before the flames of the bonfires. We knew nothing as yet of the three hundred dead, twice the daily average of the last weeks before the liberation. We could not foresee that this figure would go even higher in the months to come and that our captivity was still far from being over. We could not admit that there were some among us who would never leave Dachau alive, as its inexorable law demanded. Dachau was to become in a way the symbol of all Europe, which believed itself freed, but was really only changing masters.
Upon liberating Bergen Belsen, British soldiers discovered the true nature of the Nazi Third Reich. Bergen Belsen had reached its lowest point about three weeks before liberation. Typhus was raging and about 1000 inmates died every day from this epidemic. There was no running water and rations were down to half a pint of soup a day and bread only three times a week. Although the British soldiers had heard about Nazi atrocities, nothing prepared them for what they saw. Richard Dimbleby of the BBC (British Broadcasting Corporation), who visited Bergen Belsen a few days after liberation, broke down several times when he tried to record his first impressions of the camp. On April 19, 1945, the BBC broadcasted his report and a stunned world learned what the inmates of Bergen Belsen had gone through, and what the British soldiers had witnessed a few days before. It took the British soldiers some time to realize that the former prisoners at Bergen Belsen needed easily digested food such as rice, biscuits and fresh milk. Thousands of prisoners died after liberation because they could not get to the food that the British provided, or because they ate too much, or because they could not digest the food that was available. 
Part of Spielberg’s reluctance to make Schindler's List was that he didn’t feel that he was prepared or mature enough to tackle a film about the Holocaust. So he tried to recruit other directors to make the film. He first approached director Roman Polanski, a Holocaust survivor whose own mother was killed in Auschwitz. Polanski declined, but would go on to make his own film about the Holocaust, The Pianist, which earned him a Best Director Oscar in 2003. Spielberg then offered the movie to director Sydney Pollack, who also passed.
Schindler’s most effective tool in this privately conceived rescue campaign was the privileged status his plant enjoyed as a “business essential to the war effort” as accorded him by the Military Armaments Inspectorate in occupied Poland. This not only qualified him to obtain lucrative military contracts, but also enabled him to draw on Jewish workers who were under the jurisdiction of the SS. When his Jewish employees were threatened with deportation to Auschwitz by the SS, he could claim exemptions for them, arguing that their removal would seriously hamper his efforts to keep up production essential to the war effort. He did not balk at falsifying the records, listing children, housewives, and lawyers as expert mechanics and  metalworkers, and, in general, covering up as much as he could for unqualified or temporarily incapacitated workers.
Between the two barracks in the photo above can be seen three flags including a British flag. There were several captured British SOE men at Dachau when it was liberated. On the right is Barrack 27, where Belgian political prisoners were housed in Room 4. Catholic priests also lived in Barrack 27, but they had already been released a few days before the Americans arrived. Among the priests who survived Dachau was Father Marcel Pasiecznik, who was arrested in 1944 as a member of the underground Polish Army which fought as partisans.
With this police infrastructure in place, opponents of the Nazis were terrorized, beaten, or sent to one of the concentration camps the Germans built to incarcerate them. Dachau, just outside of Munich, was the first such camp built for political prisoners. Dachau's purpose changed over time and eventually became another brutal concentration camp for Jews.
In the aftermath of the Holocaust, many of the survivors found shelter in displaced persons  camps administered by the Allied powers. Between 1948 and 1951, almost 700,000 Jews emigrated to Israel, including 136,000 Jewish displaced persons from Europe. Other Jewish displaced persons emigrated to the United States and other nations. The last camp for Jewish displaced persons closed in 1957.

Himmler ordered the closure of ghettos in Poland in mid-July 1942; most inhabitants were sent to extermination camps. Those Jews needed for war production would be confined in concentration camps.[220] The deportations from the Warsaw Ghetto began on 22 July; over the almost two months of the Aktion, until 12 September, the population was reduced from 350,000 to 65,000. Those deported were transported in freight trains to the Treblinka extermination camp.[221] Similar deportations happened in other ghettos, with many ghettos totally emptied.[222] The first ghetto uprisings occurred in mid-1942 in small community ghettos.[223] Although there were armed resistance attempts in both the larger and smaller ghettos in 1943, in every case they failed against the overwhelming German military force, and the remaining Jews were either killed or deported to the death camps.[224]
Of a total of 2,720 clergy recorded as imprisoned at Dachau, the overwhelming majority, some 2,579 (or 94.88%) were Catholic. Among the other denominations, there were 109 Protestants, 22 Greek Orthodox, 8 Old Catholics and Mariavites and 2 Muslims. In his Dachau: The Official History 1933–1945, Paul Berben noted that R. Schnabel's 1966 investigation, Die Frommen in der Hölle ("The Pious Ones in Hell") found an alternative total of 2,771 and included the fate all the clergy listed, with 692 noted as deceased and 336 sent out on "invalid trainloads" and therefore presumed dead.[58]:276–277 Over 400 German priests were sent to Dachau.[59] Total numbers incarcerated are nonetheless difficult to assert, for some clergy were not recognised as such by the camp authorities, and some—particularly Poles—did not wish to be identified as such, fearing they would be mistreated.[58]:157

Even before the Nazis came to power in Germany in 1933, they had made no secret of their anti-Semitism. As early as 1919 Adolf Hitler had written, “Rational anti-Semitism, however, must lead to systematic legal opposition.…Its final objective must unswervingly be the removal of the Jews altogether.” In Mein Kampf (“My Struggle”; 1925–27), Hitler further developed the idea of the Jews as an evil race struggling for world domination. Nazi anti-Semitism was rooted in religious anti-Semitism and enhanced by political anti-Semitism. To this the Nazis added a further dimension: racial anti-Semitism. Nazi racial ideology characterized the Jews as Untermenschen (German: “subhumans”). The Nazis portrayed the Jews as a race and not as a religious group. Religious anti-Semitism could be resolved by conversion, political anti-Semitism by expulsion. Ultimately, the logic of Nazi racial anti-Semitism led to annihilation.
Jews were forced to move, often to different cities or countries, and live in designated areas, referred to as ghettos. Most of the ghettos were “open” which meant Jews were free to come and go during the daytime. As time past, more and more ghettos became “closed” meaning that Jews were trapped and not allowed to leave. No ghettos were ever established within the borders of Germany and most were only meant as a temporary means of isolating Jews from the German population until they could be moved elsewhere.
On arrival at Belsen with his kommondo on the night of what he believes was April 5, he was placed in a hut which was in a state of filth and overcrowding which nobody in the outside world ever dreamed could exist before Belsen was discovered. The next morning, after a roll-call lasting from 3.30 to 9, he inspected the next hut, a long, low building. Looking through a hole where a window had been, he saw one or two bodies lying about in the water on the floor of what had been the wash-place. Looking through other windows he saw piles of bodies systematically stacked, each one’s head resting on the chest of the man or woman below. The whole building was full of corpses.
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]
Every morning started with the dreaded command, "Appelle!" (roll-call!). Regardless of the weather, the prisoners were required to march outside at dawn and stand at attention in formation to be counted. Upon the command, "Hats Off!" the entire assembly of 9,000 men was required to remove all hats precisely at the same moment to the satisfaction of the SS man in charge. Prisoners sometimes practiced this and other drills for hours with some actually dropping dead from the length and rigor of roll-call. When the tally of prisoners was complete and the SS officer in command was satisfied, the prisoners were marched off to begin their 12-hour workday in a camp workshop or along the camp grounds.

The camp of huts near Fallingbostel became known as Stalag XI-B and was to become one of the Wehrmacht's largest POW camps, holding up to 95,000 prisoners from various countries.[6] In June 1940, Belgian and French POWs were housed in the former Bergen-Belsen construction workers' camp. This installation was significantly expanded from June 1941, once Germany prepared to invade the Soviet Union, becoming an independent camp known as Stalag XI-C (311). It was intended to hold up to 20,000 Soviet POWs and was one of three such camps in the area. The others were at Oerbke (Stalag XI-D (321)) and Wietzendorf (Stalag X-D (310)). By the end of March 1942, some 41,000 Soviet POWs had died in these three camps of starvation, exhaustion, and disease. By the end of the war, the total number of dead had increased to 50,000.[6] When the POW camp in Bergen ceased operation in early 1945, as the Wehrmacht handed it over to the SS, the cemetery contained over 19,500 dead Soviet prisoners.
