In the time of Rabbi Judah ha-Nasi (“Rabbi”), there was a revolution in the relationships between the authorities and the Jews in Palestine. This revolution was linked with the special personality of Rabbi and his way of leadership, as well as the succession of the Severan dynasty to the imperial throne, and Roman policy in the provinces in general in the time of the Severans. After the Severans came the imperial crisis, which left its mark especially on the eastern provinces, which were subjected to such a heavy economic burden that many Jews emigrated to Babylonia, the home of the largest Jewish diaspora community outside the borders of the Roman empire.
