The first document referring to an organized Jewish community in Thessaloniki is that of the Acts of the Apostles. This community was visited by St. Paul around 50 C.E.; he preached at its synagogue on “three consecutive Sabbaths”. Burial finds date back to the first C.E. centuries. Written references from the 12th and 13th centuries document the existence of a Jewish community and a Jewish quarter. In the late 15th and early 16th centuries, Jewish refugees settled here from the Iberian Peninsula, Sicily, Italy, North Africa, Germany and Provence, making Thessaloniki the only city in Greece where the majority of the population was Jewish.
