ר׳ משה בן אליהו קפשאלי

ר׳ משה בן אליהו קפשאלי (c.1420–c.1495) was the principal rabbinic and communal leader of Constantinople during the transition from Byzantine to Ottoman rule. Born into a prominent family at Candia on Venetian Crete, he travelled as a young scholar through the German lands and studied in Ashkenazi yeshivot. By about 1450 he was serving the Jewish community of Constantinople. After Mehmed II conquered the city in 1453, the sultan recognized ר׳ משה as the community’s senior representative. His authority included adjudication, supervision of communal taxation and influence over rabbinic appointments, although modern scholarship cautions against treating this early arrangement as identical to the later centralized office of Hakham Bashi. He was renowned for personal integrity and for enforcing marriage and family law, but accusations sent to ר׳ יוסף קולון produced a major controversy; after receiving fuller testimony, ר׳ יוסף withdrew his condemnation. Under Bayezid II, ר׳ משה helped organize assistance and settlement for refugees from Spain and Portugal and mediated the tax burden between wealthy and poor households. His surviving learning is dispersed mainly through responsa, rulings and citations rather than a single securely transmitted major book. He died in Constantinople around 1495 and was succeeded in communal prominence by ר׳ אליהו מזרחי.
