A historical investigation of children’s memory of the Holocaust in Greece illustrates that age, generation and geographical background shaped postwar Jewish identities. The examination of children’s narratives deposited in the era of digital archives enables an understanding of the age-specific construction of the memory of genocide, which shakes established assumptions about the memory of the Holocaust. In the context of a globalized Holocaust memory established through testimony archives, the present research constructs a genealogy of the testimonial culture in Greece by framing the rich source of written and oral testimonies in the political discourses and public memory of the aftermath of the Second World War. The testimonies of former hidden children and child survivors of concentration camps illuminate the questions that haunted postwar attempts to reconstruct communities, related to the specific evolution of genocide in Greece and to the rising anti-Semitism of postwar Greece. As an oral history of child survivors of the Holocaust, the book will be of interest to researchers in the fields of the history of childhood, Jewish studies, memory studies, Holocaust and genocide studies.
