The Greek island of Corfu, formerly known as Corcyra, might be most famous for Thucydides’ description of it during the Peloponnesian War. In more recent times, it was home to a small but thriving Jewish community that was systematically destroyed by the Nazis. Nimrod Gaatone tells its story:
Jews are known to have been present in Corfu since the Middle Ages. The famous traveler Benjamin of Tudela mentions visiting the island in the 12th century and encountering a Jew named Yosef, who worked as a dyer of fabrics. Two major communities lived on the island: one composed of Romaniote Jews and the other of Italian Jews.
The Jews of Corfu dealt primarily in [commerce], and some of them became prominent in trading in etrogim (citrons) grown on the island, which were considered particularly aesthetic and beautiful and therefore appropriate for the holiday of Sukkot. The Jewish traders tended to acquire the etrogim from Christian farmers and then export them throughout the Jewish world. During the 19th century, a religious debate raged across Jewish communities worldwide regarding the kosher status of these etrogim, and some communities preferred to acquire etrogim from other sources instead.
