The Karaites reject the Oral Law, and split off from now mainstream Rabbinic Judaism.
Major Karaite personages include Anan ben David, Benjamin of Nahawandi (830 CE), Daniel al–Kumsi (900 CE).
After mainstream Rabbinic Saadia Gaon of Egypt (noted above) ascends to the head of Sura Academy in Babylonia in 928 CE, and writes his masterwork “Beliefs and Opinions” (Emunoth ve–Deoth), which traces and elucidates the philosophical basis for Rabbinic Judaism, Karaism fades from the stage.
