Your savior didn't save them for long :
First Jewish–Roman War
Emperor Nero appointed general Vespasian to crush the rebellion.By the year 68, Jewish resistance in the north had been crushed, and Vespasian made Caesarea Maritima his headquarters and proceeded to methodically clear the coast.By the summer of 70, the Romans had breached the walls of Jerusalem, ransacking and burning nearly the entire city. The defeat of the Jewish revolt altered the Jewish diaspora, as many of the Jewish rebels were scattered or sold into slavery. Josephus claims that 1,100,000 people were killed during the siege, a sizeable portion of these were at Jewish hands and due to illnesses brought about by hunger.
Bar Kokhba revolt 132–136 AD
The outbreak took the Romans by surprise. Hadrian called his general Sextus Julius Severus from Britain, and troops were brought from as far as the Danube. The size of the Roman army amassed against the rebels was much larger than that commanded by Titus sixty years earlier. Roman losses were very heavy. The XXII Deiotariana was disbanded after serious losses.
The struggle lasted for three years before the revolt was brutally crushed in the summer of 135. After losing Jerusalem, Bar Kokhba and the remnants of his army withdrew to the fortress of Betar, which also subsequently came under siege. The Jerusalem Talmud relates that the numbers slain were enormous, that the Romans "went on killing until their horses were submerged in blood to their nostrils". The Talmud also relates that for seventeen years the Romans did not allow the Jews to bury their dead in Betar.
And finally the were finished of by Byzantium in 629. (source wikipeadia)
