Addresses the history and challenges of using "antisemitism" and related terms as tools for historical analysis and public discourse. It encourages readers to rethink long-standing assumptions regarding the meaning of Jewish history and the history of relations between Jews and their neighbours. The book begins with a revised version of David Engel's seminal essay "Away from a Definition of Antisemitism." Subsequent contributions explore the various definitions and uses of the term "antisemitism" in a range of contexts, including ancient Rome and Greece; the Byzantine Empire; medieval, early modern, and modern Europe; and North America, and discusses the Holocaust and its memory.
