Earlier this week I hosted a virtual speaker from the Northwestern University Holocaust Educational Foundation Virtual Speakers Bureau who gave an excellent talk on psychology and the Holocaust. During the Q&A, one of the students asked a comparative question. She mentioned that in addition to the Jews, others groups were persecuted by the Nazi regime and murdered during the Holocaust. She asked if that was unique or if there were multiple victim groups in other genocides. Both the speaker and I thought this was a great question, but neither of us had an answer.
In this one aspect, how does the Holocaust compare to or contrast with other genocides? If multiple groups were targeted in another genocide, were these groups targeted concurrently or consecutively?
Thanks in advance for any information.
