Few events, if any, in the modern era have had more impact than the Holocaust. This four-volume landmark study, with over a hundred contributions from leading scholars in the field, represents the most wide-ranging effort in decades to grapple with the catastrophe. The collection is united by three central aims: presenting a thorough analysis of the Holocaust, reviewing its vast, multilingual historiography, and rendering visible its impact on the post-war world. Volumes examine the origins and preconditions of the Holocaust, its policies and participants, the victims, bystanders, and helpers, and finally its outcomes and repercussions. Throughout the volumes, essays offer multi-perspectival discussions of the Holocaust, moving beyond a narrow focus on high-level decisions to consider widening circles of participation and diverse groups of participants. Further attention is paid to the integration of other historiographies into English language scholarship, including the rich Jewish scholarship of the early post-war period. The Cambridge History of the Holocaust offers an authoritative review of existing scholarship, and stimulating new interpretations of under-researched areas.
