Book excerpt: This book examines the social psychological processes involved in experiences of collective victimization and oppression, as well as the consequences of these experiences for individuals and for relations within and between groups. In twenty chapters, authors explore questions such as: How are experiences of collective victimization passed down and understood? How do people cope with and make sense of these experiences? Who is included and excluded from the category of "victims," and what are the psychological consequences of such denial versus acknowledgment of collective victimization? And finally, what are the ethics of researching collective victimization, especially when these experiences are recent or politically contested?
