Approximately at the same time, large portions of the Jewish population in the Empire rose in rebellion, uprisings taking place almost simultaneously in Judea, Egypt, Libya, Cyprus and parts of Mesopotamia. The grain supply from Egypt to Rome was threatened and with local authorities unable to quell the rebellion, Trajan sent Turbo, by then one of his best military men and closest confidants, to Egypt to deal with the situation. Turbo reestablished control over Egypt and eventually Cyprus. Turbo became the military Prefect of Egypt for several years while the province went through a process of rehabilitation.
