Holocaust studies deal with the myriad aspects of the mass murder of Jews. The subject of genocide overshadows the very important impact the Holocaust has made on post-war societies. This impact covers many disciplines such as sociology, psychology, law, theology, ethics, philosophy, politics, medical issues, history, literature, art, and others. Only by grouping all of these disciplines together in one area, Post-Holocaust Studies, can one understand multi-disciplinary issues such as migration and other survivor subjects, restitution, memory, etc. The grouping of post-Holocaust issues also provides a looking-glass on contemporary societies.
