Dachau was the first and most important camp at which German doctors and scientists set up laboratories using inmates as involuntary guinea pigs for such experiments as determining the effects on human beings of sudden increases and decreases in atmospheric pressure, studying the effects of freezing on warm-blooded creatures, infecting prisoners with malaria and treating them with various drugs with unknown effects, and testing the effects of drinking seawater or going without food or water. Continued throughout World War II, such experiments and the harsh living conditions made Dachau one of the most notorious of camps. After the war, the scientists and doctors from this and other camps were tried at Nürnberg in the “Doctors’ Trial”; seven were sentenced to death. (See Nürnberg trials.)
In May 1944, Martin Gottfried Weiss was appointed the department head of the Office Group D in the SS Main Office of Economic Administration (WVHA) at Oranienburg. That same year, Weiss became the commander of the five sub-camps of Dachau at Mühldorf; when the Mühldorf prisoners were evacuated and brought to the main camp in the Spring of 1945, Weiss returned to Dachau. Fourteen members of the staff at Mühldorf were put on trial at Dachau from April 1 through May 13, 1947 in the case of US vs. Franz Auer et al.
The number of prisoners incarcerated in Dachau between 1933 and 1945 exceeded 188,000. The number of prisoners who died in the camp and the subcamps between January 1940 and May 1945 was at least 28,000, to which must be added those who perished there between 1933 and the end of 1939, as well as an uncounted number of unregistered prisoners. It is unlikely that the total number of victims who died in Dachau will ever be known.
In the German parliament, the Nazi party, led by Adolf Hitler, gained popularity. The number of seats Nazis controlled in the parliament rose from 12 in 1928 to 230 in 1932, making them the largest political party. The strong showing guaranteed the Nazi party would need to be part of any political coalition. Believing he could check Hitler’s ambition, President Hindenburg reluctantly made Hitler the Chancellor of Germany on January 30, 1933.
By late 1938, the Nazis could claim an impressive series of successes. Germany had staged the 1936 Olympics, annexed Austria and part of Czechoslovakia, and was in the midst of a strong economic recovery fuelled by rearmament. These triumphs had increased the Nazis' popularity and their confidence. President Hindenburg had died and all opposition parties had been abolished. The last conservatives in the cabinet had been replaced by Nazis. The way was clear for radical action.
Over the 12 years of use as a concentration camp, the Dachau administration recorded the intake of 206,206 prisoners and deaths of 31,951. Crematoria were constructed to dispose of the deceased. Visitors may now walk through the buildings and view the ovens used to cremate bodies, which hid the evidence of many deaths. It is claimed that in 1942, more than 3,166 prisoners in weakened condition were transported to Hartheim Castle near Linz, and were executed by poison gas because they were deemed unfit.[15]:137[21]
On November 12, 1938, Field Marshal Hermann Göring convened a meeting of Nazi officials to discuss the damage to the German economy from pogroms. The Jewish community was fined one billion Reichsmarks. Moreover, Jews were made responsible for cleaning up the damage. German Jews, but not foreign Jews, were barred from collecting insurance. In addition, Jews were soon denied entry to theatres, forced to travel in separate compartments on trains, and excluded from German schools. These new restrictions were added to earlier prohibitions, such as those barring Jews from earning university degrees, from owning businesses, or from practicing law or medicine in the service of non-Jews. The Nazis would continue to confiscate Jewish property in a program called “Aryanization.” Göring concluded the November meeting with a note of irony: “I would not like to be a Jew in Germany!”

The Nazis introduced a racial hierarchy—keeping Poles in harsh conditions, while favoring German priests.[58]:148 697 Poles arrived in December 1941, and a further 500 of mainly elderly clergy were brought in October the following year. Inadequately clothed for the bitter cold, of this group only 82 survived. A large number of Polish priests were chosen for Nazi medical experiments. In November 1942, 20 were given phlegmons. 120 were used by Dr Schilling for malaria experiments between July 1942 and May 1944. Several Poles met their deaths with the "invalid trains" sent out from the camp, others were liquidated in the camp and given bogus death certificates. Some died of cruel punishment for misdemeanors—beaten to death or run to exhaustion.[58]:148–9
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]
For the role, Spielberg cast then relatively unknown Irish actor Liam Neeson, whom the director had seen in a Broadway play called Anna Christie. “Liam was the closest in my experience of what Schindler was like,” Spielberg told The New York Times. “His charm, the way women love him, his strength. He actually looks a little bit like Schindler, the same height, although Schindler was a rotund man,” he said. “If I had made the movie in 1964, I would have cast Gert Frobe, the late German actor. That’s what he looked like.”
Between the years 1933 and 1945, more than 3.5 million Germans were imprisoned in such concentration camps or prison for political reasons.[49][50][51] Approximately 77,000 Germans were killed 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 were considered to enable them to engage in subversion and conspiracy against the Nazis.[52]

Some ghettos were initially open, which meant that Jews could leave the area during the daytime but had to be back by a curfew. Later, all ghettos became closed, meaning that Jews were not allowed to leave under any circumstances. Major ghettos were located in the cities of Polish cities of Bialystok, Lodz, and Warsaw. Other ghettos were found in present-day Minsk, Belarus; Riga, Latvia; and Vilna, Lithuania. The largest ghetto was in Warsaw. At its peak in March 1941, some 445,000 were crammed into an area just 1.3 square miles in size.
At first a single barrack accommodated only 180 persons, but later the overcrowding became intolerable, and bunks filled all available space. At the north end of Dachau stood the disinfection buildings and an Angora rabbit farm. The camp had a unique feature, the Dachau museum, containing plaster-images of prisoners marked by bodily defects or other strange characteristics.

Joseph Goebbels made a speech at the beer hall in which he said that he would not be surprised if the German people were so outraged by the assassination of German diplomat Ernst vom Rath by a Polish Jew named Herschel Grynszpan that they would take the law into their own lands and attack Jewish businesses and Synagogues. Goebbels is generally credited with being the instigator of the pogrom. (Pogrom is a Polish word which means an event in which ordinary citizens use violence to drive the Jews out.)
Known as Kristallnacht (or "Night of Broken Glass"), the attacks were partly carried out by the SS and SA,[122] but ordinary Germans joined in; in some areas, the violence began before the SS or SA arrived.[123] Over 7,500 Jewish shops (out of 9,000) were looted and attacked, and over 1,000 synagogues damaged or destroyed. Groups of Jews were forced by the crowd to watch their synagogues burn; in Bensheim they were forced to dance around it, and in Laupheim to kneel before it.[124] At least 90 Jews died. The damage was estimated at 39 million Reichmarks.[125] Cesarani writes that "[t]he extent of the desolation stunned the population and rocked the regime."[120] Thirty-thousand Jews were sent to the Dachau, Buchenwald and Sachsenhausen concentration camps.[126] Many were released within weeks; by early 1939, 2,000 remained in the camps.[127] German Jewry was held collectively responsible for restitution of the damage; they also had to pay an "atonement tax" of over a billion Reichmarks. Insurance payments for damage to their property were confiscated by the government. A decree on 12 November 1938 barred Jews from most of the remaining occupations they had been allowed to hold.[128] Kristallnacht marked the end of any sort of public Jewish activity and culture, and Jews stepped up their efforts to leave the country.[129]
But in the spring of 1945, photographs and eyewitness accounts from the liberation of camps like Bergen-Belsen afforded the disbelieving world outside of Europe its first glimpse into the abyss of Nazi depravity. All these years later, after countless reports, books, oral histories and documentary films have constructed a terrifyingly clear picture of the Third Reich's vast machinery of murder, it's difficult to grasp just how shocking these first revelations really were. The most horrific rumors about what was happening to the Jews and millions of other "undesirables—Catholics, pacifists, homosexuals, Slavs—in Nazi-occupied lands paled before the reality revealed by the liberation of the camps.
Throughout the spring and summer of 1940, the German army expanded Hitler’s empire in Europe, conquering Denmark, Norway, the Netherlands, Belgium, Luxembourg and France. Beginning in 1941, Jews from all over the continent, as well as hundreds of thousands of European Gypsies, were transported to the Polish ghettoes. The German invasion of the Soviet Union in June 1941 marked a new level of brutality in warfare. Mobile killing units called Einsatzgruppenwould murder more than 500,000 Soviet Jews and others (usually by shooting) over the course of the German occupation.
In April 1943, a part of the Bergen-Belsen camp was taken over by the SS Economic-Administration Main Office (SS Wirtschafts-Verwaltungshauptamt; WVHA). It thus became part of the concentration camp system, run by the SS Schutzstaffel but it was a special case.[7] Having initially been designated a Zivilinterniertenlager ("civilian internment camp"), in June 1943 it was redesignated Aufenthaltslager ("holding camp"), since the Geneva Conventions stipulated that the former type of facility must be open to inspection by international committees.[8] This "holding camp" or "exchange camp" was for Jews who were intended to be exchanged for German civilians interned in other countries, or for hard currency.[9] The SS divided this camp into subsections for individual groups (the "Hungarian camp", the "special camp" for Polish Jews, the "neutrals camp" for citizens of neutral countries and the "Star camp" for Dutch Jews). Between the summer of 1943 and December 1944 at least 14,600 Jews, including 2,750 children and minors were transported to the Bergen-Belsen "holding" or exchange camp.[10]:160 Inmates were made to work, many of them in the "shoe commando" which salvaged usable pieces of leather from shoes collected and brought to the camp from all over Germany and occupied Europe. In general the prisoners of this part of the camp were treated less harshly than some other classes of Bergen-Belsen prisoner until fairly late in the war, due to their perceived potential exchange value.[9] However, only around 2,560 Jewish prisoners were ever actually released from Bergen-Belsen and allowed to leave Germany.[9]
