Persecutors and Victims: In the ghetto of Lodz (1940 - 1944), left Hans Biebow, the head of the German ghetto administration, in the background members of the Jewish ghetto police.
The mass crimes of the Third Reich were based ultimately on the idea that the value-laden hierarchy of races existed. In World War II these ideas were implemented in their most radical form - with the systematic murder of men, women, and children. Above all the Jews, but also Roma, became victims of segregation, persecution, and genocide. Mentally and physically handicapped persons were considered to be "unworthy of life" and were also murdered in large numbers. Terror reigned all over German-occupied Europe, particularly, however, in Poland and the Soviet Union.
