The Geonim: Leaders of the Jewish World from Baghdad

From My Jewish Learning

From the eighth to the eleventh centuries, the heads of the Jewish academies of Babylonia, known as the geonim, were the highest religious authorities for Jews across much of the world. This article by the historian Eli Barnavi, adapted from his Historical Atlas of the Jewish People, explains how they came to lead.

More than a school

The academy as a court

The great academies of Sura and Pumbedita were not only places of study. They served as the supreme court of Jewish law, and the gaon who led each one appointed judges, community leaders, scribes, and other officials. In the early ninth century, both academies moved to Baghdad, the capital of the Abbasid caliphate.

Rival centers

Babylonia and the Land of Israel

The academy in the Land of Israel guided the Jews of Palestine, Syria, Lebanon, and Egypt, while Babylonia guided Iraq, Iran, and Yemen. The two competed for the loyalty of North Africa's Jews. Babylonia won, thanks to the reach of the caliphate, the prestige of the Babylonian Talmud, and the eastern roots of many North African Jews. By the tenth century, Baghdad's academies led most of the Jewish world.

Letters across the world

Questions and answers

Communities sent questions and donations to the academies, and the geonim answered with responsa, written rulings on Jewish law, along with commentaries and honors for their supporters. These letters tied Jewish communities from Spain to Persia to Baghdad.

Saadia Gaon

The greatest of the geonim

Saadia ben Joseph (882 to 942), born in Egypt, settled in Babylonia and became the most famous gaon of all. In 922 he played a central role in a dispute over the Jewish calendar, after which most communities followed Babylonia's calendar. In the Muslim world, Barnavi writes, only Maimonides, three centuries later, would surpass his authority.
