Six million Jews in central Europe were systematically murdered by the Nazis and their collaborators during the Second World War; the horrific event we know as the Holocaust. Jews call it the Shoah.
The horrors in Nazi Europe progressed from informal to legal discrimination, to governmentally sanctioned violence (Kristallnacht), to internments, to the death camps where an entire race of people were to meet their deaths. At any point this escalation could have been halted; one theme of this gallery is that individuals make choices to act or not to act. The Holocaust was not inevitable.
