In October 2021, Imperial War Museums (IWM) opened its new Holocaust Galleries in its London branch, replacing its first Holocaust Exhibition (from 2000) that had become a landmark in British Holocaust memory. Because of its comprehensive nature and intricate scenography, the new Holocaust Galleries are at the centre of almost all recent major narrative, political, and ethical debates about Holocaust representation in museums. The book provides an ideal global case-study understanding the possibilities and limitations of re-presenting trauma and violence in museums today and whether Holocaust exhibitions can promote democratic, civic, or human rights values, making it an important resource for museum practitioners, public history educators, and university researchers alike, interested in Historical, Museum, Memory, Holocaust, Genocide, or Cultural Studies. The volume brings together texts written by museum practitioners and academic scholars. It is divided in three parts: a long essay by James Bulgin, Head of Content for the new Holocaust Galleries, about the genesis and implementation of the exhibition, supplemented with briefer essays by educators and community members involved in the development of the exhibition, an extensive interview by Stephan Jaeger with IWM researchers James Bulgin and Suzanne Bardgett, and an extensive part with six critical essays by university scholars analysing the new Holocaust Galleries from numerous theoretical angles.
