For rabbis of different epochs bearing the "Gaon" title see Gaon. Geonim (also Gaonim) (Hebrew: גאונים) were the presidents of the two great rabbinical colleges of Sura and Pumbedita, in Babylonia, and were the generally accepted spiritual leaders of the Jewish community world wide in the early medieval era, in contrast to the Resh Galuta (Exilarch) who wielded secular authority over the Jews in Islamic lands.
