David ben Zakkai
David ben Zakkai was an exilarch, leader of the Jewish community of Babylon, known in Jewish history especially for his conflict with Saadia Gaon, which ruptured the leadership of the Babylonian Jews, and which was settled by the intervention of the Abbasid Caliph Al-Qahir.
He was banished to Khorasan, where he died.
Biographical details
He was a relative of the Prince of the Exile, 'Uḳba, who had been deposed from office and banished, and was his successor in the exilarchate.Exilarchate
The office of Exilarch was at this time confronted by a dangerous adversary in the person of the passionate and ambitious gaon Mar Kohen-Zedek, who attempted to make the Academy of Pumbedita the only center of the Babylonian Jews, thereby threatening the existence of the sister academy of Sura. He, as well as the Academy of Pumbedita, refused to recognize David as exilarch, whereupon the latter, who was equally resolute and ambitious, deposed Kohen-Ẓedeḳ and appointed another gaon.This dispute lasted for two years, until Nissim Naharwani, highly respected for his piety, intervened and reconciled the adversaries, peace being concluded at Sarsar. Kohen-Ẓedeḳ and his college accompanied the exilarch as far as Baghdad ; David ben Zakkai, in turn, recognizing the former as gaon of Pumbedita. But the reputation of the Academy of Sura continued to dwindle.
Relationship with Saadia Gaon
A weaver filled the office of gaon for two years, and the ancient and famous academy of Sura was on the point of being dissolved, when Saadia, called from Egypt by the exilarch, was appointed gaon. This was against the advice of Naharwani, who favored Ẓemaḥ ibn Shahin ; but the wisdom of the choice was shown when Saadia made the fame of Sura surpass even that of Pumbedita.Inheritance case
The friendly relations between David ben Zakkai and Saadia were soon disturbed. David shrank from nothing which might strengthen his position, and misused his influence in order to extort large contributions from the community. A case of inheritance which David had decided illegally for reasons of self-interest, led to a rupture between the two. The exilarch asked the two geonim to sign the document in question. Kohen-Ẓedeḳ dared not refuse, but Saadia did. David deposed Saadia from office and banished him, appointing in his place the insignificant Joseph b. Jacob b. Satia. Saadia, however, took up the gauntlet; he, in turn, deposed David, and, together with his followers, appointed David's brother, Josiah Ḥasan, as exilarch.The Babylonian Jews were now divided into two parties, each of which appealed to the caliph Al-Muḳtadir. His successor, Al-Ḳahir, finally decided the case. The opposing exilarch was banished to Khorasan, where later on he died; and Saadia was deprived of his gaonate.
