This online learning environment centers on the life cycle of Jews who lived in Salonika, Greece before, during, and after World War II. The Jewish community of Salonika was one of the most ancient in Europe. Before World War II, 55,200 Jews lived in Salonika, comprising two-thirds of the population. By the end of the Holocaust, only one-fourth (1,950 souls) of the Jewish population remained. This educational unit presents a case study that can help teachers and students find an example of how to uncover and reconstruct the life of a particular community through a variety of materials. The theme for this year’s Holocaust Martyrs’ and Heroes’ Remembrance Day is “The Faces Behind Documents, Artifacts, and Photographs.” These various items are memory fragments that remain after the devastation of the Holocaust. The unit before you utilizes materials found on Yad Vashem's online databases. Using historical sources, photographs, artifacts, films, and other forms of evidence, they have attempted to depict the Jewish community of Salonika, before and after the Holocaust.
