SS-Obergruppenführer Reinhard Heydrich, head of the Reich Main Security Office (Reichssicherheitshauptamt or RSHA), convened what became known as the Wannsee Conference on 20 January 1942 at Am Großen Wannsee 56–58, a villa in Berlin's Wannsee suburb. The meeting had been scheduled for 9 December 1941, and invitations had been sent on 29 November, but it had been postponed.
After the liberation of Dachau, the commanding officer of the Rainbow division, Major General Harry J. Collins, made sure that the Jewish survivors were taken care of properly. Some of the Jewish survivors were given private housing in homes in the town of Dachau after their owners had been evicted. In some cases, the home owners were allowed to live in the attic of their homes, but they were forbidden to remove any of the linens, china or silverware, which had to be left for the use of the new occupants. A few of the Jewish survivors settled in Dachau permanently after the war.
The anti-Hitler movement inside Germany, which included German communists and Jehovah's Witnesses, was the largest indigenous resistance movement of any country during the whole war. Only in Germany was an attempt made to assassinate their leader. Around 800,000 were sent to prison at one time or another for active resistance to the regime. While the western allies did all in their power to help other resistance movements, ie in France and the Netherlands, they did nothing to help or encourage the movement in Germany which in all probability could have ended the war sooner. But the Allies were intent on unconditional surrender and refused to make any deals at all with Germans. Accordingly the Allies viewed all Germans as bad, not only Nazis.
The Germans' overwhelming repression and the presence of many collaborators in the various local populations severely limited the ability of the Jews to resist. Jewish resistance did occur, however, in several forms. Staying alive, clean, and observing Jewish religious traditions constituted resistance under the dehumanizing conditions imposed by the Nazis. Other forms of resistance involved escape attempts from the ghettos and camps. Many who succeeded in escaping the ghettos lived in the forests and mountains in family camps and in fighting partisan units. Once free, though, the Jews had to contend with local residents and partisan groups who were often openly hostile. Jews also staged armed revolts in the ghettos of Vilna, Bialystok, Bedzin-Sosnowiec, krakow, and Warsaw.
Medical experiments conducted on camp inmates by the SS were another distinctive feature. At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later. Twenty-three senior physicians and other medical personnel were charged at Nuremberg, after the war, with crimes against humanity. They included the head of the German Red Cross, tenured professors, clinic directors, and biomedical researchers. Experiments took place at Auschwitz, Buchenwald, Dachau, Natzweiler-Struthof, Neuengamme, Ravensbrück, Sachsenhausen, and elsewhere. Some dealt with sterilization of men and women, the treatment of war wounds, ways to counteract chemical weapons, research into new vaccines and drugs, and the survival of harsh conditions.
Throughout the Middle Ages in Europe, Jews were subjected to antisemitism based on Christian theology, which blamed them for killing Jesus. Even after the Reformation, Catholicism and Lutheranism continued to persecute Jews, accusing them of blood libels and subjecting them to pogroms and expulsions. The second half of the 19th century saw the emergence in the German empire and Austria-Hungary of the völkisch movement, which was developed by such thinkers as Houston Stewart Chamberlain and Paul de Lagarde. The movement embraced a pseudo-scientific racism that viewed Jews as a race whose members were locked in mortal combat with the Aryan race for world domination. These ideas became commonplace throughout Germany, with the professional classes adopting an ideology that did not see humans as racial equals with equal hereditary value. Although the völkisch parties had support in elections at first, by 1914 they were no longer influential. This did not mean that antisemitism had disappeared; instead it was incorporated into the platforms of several mainstream political parties.
Eicke's idea was that through a combination of severe discipline, Spartan living conditions and forced labor, he could reform any so-called 'Enemy of the State,' then set him free to resume a useful life in Hitler's Germany. Inside the camp, painted in large letters along the roof of one building was the motto: "There is one way to freedom. Its milestones are: obedience, zeal, honesty, order, cleanliness, temperance, truth, sense of sacrifice and love for the Fatherland."
In March 1944, part of the camp was redesignated as an Erholungslager ("recovery camp"), where prisoners too sick to work were brought from other concentration camps. They were in Belsen supposedly to recover and then return to their original camps and resume work, but many of them died in Belsen of disease, starvation, exhaustion and lack of medical attention.
