Genocide is widely acknowledged as ‘the crime of crimes’. Such universal condemnation understandably triggers both loose talk (calling each and every massacre ‘genocide’) and utter reluctance in political circles to use the ‘G-word’. The social construction of genocide reflects the deeper question whether the rigid legal concept of genocide – as it emerges in the Genocide Convention and has been maintained ever since – still corresponds with the historical and social perception of the phenomenon. This book is the product of an intellectual encounter between scholars of historical and legal disciplines which have joined forces to address this question. The authors are strongly inspired by the idea that the multi-disciplinary research of and education on genocide may contribute to a more appropriate reaction and prevention of genocide.
