Mar Ukva

Mar Ukva held the most powerful Jewish office in Babylonia: Resh Galuta, the Head of the Diaspora, the community's leading authority under Persia's Sassanid kings. He was an Amora — one of the rabbis whose debates built the Talmud — of the first generation, active in Kafri during the early third century. He helped establish the prestige and autonomy of the Babylonian Jewish community and was known for his piety, legal acumen, and charitable works. He studied under earlier masters and was a contemporary of Rav and Samuel, engaging in vigorous halakhic debates over Jewish law that shaped Babylonian rabbinic tradition. His decisions and interpretations were widely respected, and he played a crucial role in transmitting Jewish learning during a formative period of the Talmud.
