Over the decades, the Holocaust has remained a critical issue both historically and politically. This is due to the modernisation of anti-Semitism in the West, where accusations of ritual murder have long been passe and claims that the Holocaust was a hoax are de riguer, and to the government sanctions of anti-Semitism in the East in countries such as Iran. The purely scholarly problem of determining the number of victims, like other aspects of demography related to the Holocaust, have suddenly become closely embroiled in geopolitics and the phenomenon of Holocaust denial, which is now a context that has been forced upon it. This book is imbued with these connections and interrelationships. Avraham, Wolfgang Benz, Sergio Della Pergola, Mark Kupovetsky, Dieter Pohl, Aron Shneer, and the editors contribute their voices to the topic.
