This book investigates the July 4, 1946, Kielce pogrom, a milestone in the periodization of the Jewish diaspora. This massacre compelled thousands of Polish Jews who survived the Holocaust to flee postwar Poland. It remains a negative reference point in the Polish historical narrative and represents a lack of reckoning with the role of antisemitism in postwar Polish society and identity politics. The book weaves together the voices of the Kielce pogrom survivors, witnesses, and perpetrators with a myriad of other archival sources. In doing so, it exposes wartime and postwar biographies of local factory workers, city and church officials, local police officers, and members of the security service, some of whom participated in the Holocaust and then directly or indirectly participated in the Kielce pogrom. The book paints a social portrait that explores people's behavior in light of forces and emotions greater than themselves. It reconstructs a postwar communist system that, despite promises to combat deeply rooted antisemitism, not only failed to prevent its spread but turned a blind eye to it and eventually used it to legitimize itself. Cursed is a microhistory that recreates the events of the Kielce pogrom step by step and examines the dominant hypotheses about the pogrom through the prism of previously classified archival evidence. It offers readers a nuanced analysis that cuts across social and ideological divisions. The resulting narrative is filled with new discoveries not only about the Kielce pogrom but about the nature of antisemitism, hostility toward minorities, and collective violence.
