After Judah's death Sepphoris did not long remain the seat of the patriarch and the Academy. Gamaliel III, the unpretentious son of a distinguished father, became patriarch; but Hanina bar Hama succeeded him as head of the school, and introduced the new order of things that commenced with the completion of the Mishnah. In Hanina's lifetime the last migration of the Sanhedrin occurred. His pupil, Johanan bar Nappaha, settled in Tiberias, and the patriarch Judah II (grandson of Judah I) soon found himself compelled to remove to that city. The imposing personality and unexampled learning of Johanan rendered Tiberias for a long period the undisputed center of Levantine Judaism, the magnet which attracted Babylonian students.
