The Jews' Great Revolt against Rome in 66 C.E. led to one of the greatest catastrophes in Jewish life and, in retrospect, might well have been a terrible mistake.
No one could argue with the Jews for wanting to throw off Roman rule. Since the Romans had first occupied Israel in 63 B.C.E., their rule had grown more and more onerous. From almost the beginning of the Common Era, Judea was ruled by Roman procurators, whose chief responsibility was to collect and deliver an annual tax to the empire. Whatever the procurators raised beyond the quota assigned, they could keep. Not surprisingly, they often imposed confiscatory taxes. Equally infuriating to the Judeans, Rome took over the appointment of the High Priest (a turn of events that the ancient Jews appreciated as much as modern Catholics would have appreciated Mussolini appointing the popes). As a result, the High Priests, who represented the Jews before God on their most sacred occasions, increasingly came from the ranks of Jews who collaborated with Rome.
