About 400 years before the birth of Jesus, Jews and Romans started interacting. When hardships due to war in the east became to burdensome many Jews moved to Rome (As well as other parts of Europe).
The Sicarii were led by descendents of Judas of Galilee, who helped foster revolt against direct Roman rule in 6 CE, when they attempted to carry out a census of the Jews under the rule of Roman governor Quirinius in Syria, so that they could tax them. Judas famously proclaimed that the Jews should be ruled by God alone.Sicarii terrorism began as Jewish resistance to Roman rule in the region, which began in 40 BCE. Fifty six years later, in 6 CE, Judea and two other districts were combined and put under the control of Roman rule in what would later be considered greater Syria. Jewish groups began violent resistance to Roman rule around 50 CE, when the Sicarii and other groups started using guerrilla or terrorist tactics. All out war between the Jews and the Romans broke out in 67, when Romans invaded. The war ended in 70 CE, when Roman forces devastated Jerusalem. Masada, Herod’s famous fortress was conquered by siege in 74. http://www.ccel.org/j/josephus/works/… The Roman legions surrounded the city and began to slowly squeeze the life out of the Jewish stronghold. By the year 70, the attackers had breached Jerusalem’s outer walls and began a systematic ransacking of the city. The assault culminated in the burning and destruction of the Temple that served as the center of Judaism. In victory, the Romans slaughtered thousands. Of those sparred from death: thousands more were enslaved and sent to toil in the mines of Egypt, others were dispersed to arenas throughout the Empire to be butchered for the amusement of the public. The Temple’s sacred relics were taken to Rome where they were displayed in celebration of the victory. The rebellion sputtered on for another three years and was finally extinguished in 73 AD with the fall of the various pockets of resistance including the stronghold at Masada. “…the Jews let out a shout of dismay that matched the tragedy.” Our only first-hand account of the Roman assault on the Temple comes from the Jewish historian Josephus Flavius. Josephus was a former leader of the Jewish Revolt who had surrendered to the Romans and had won favor from Vespasian. In gratitude, Josephus took on Vespasian’s family name – Flavius – as his own. We join his account as the Romans fight their way into the inner sanctum of the Temple: “…the rebels shortly after attacked the Romans again, and a clash followed between the guards of the sanctuary and the troops who were putting out the fire inside the inner court; the latter routed the Jews and followed in hot pursuit right up to the Temple itself. Then one of the soldiers, without awaiting any orders and with no dread of so momentous a deed, but urged on by some supernatural force, snatched a blazing piece of wood and, climbing on another soldier’s back, hurled the flaming brand through a low golden window that gave access, on the north side, to the rooms that surrounded the sanctuary. As the flames shot up, the Jews let out a shout of dismay that matched the tragedy; they flocked to the rescue, with no thought of sparing their lives or husbanding their strength; for the sacred structure that they had constantly guarded with such devotion was vanishing before their very eyes.
history of the Jews in the Roman Empire traces the interaction of Jews and Romans during the period of the Roman Empire (27 BC – AD 476). Their cultures began to overlap in the centuries just before the Christian Era. Jews, as part of the Jewish diaspora, migrated to Rome and Roman Europe from the Land of Israel, Asia Minor, Babylon and Alexandria in response to economic hardship and incessant warfare over the land of Israel between the Ptolemaic and Seleucid empires. In Rome, Jewish communities enjoyed privileges and thrived economically, becoming a significant part of the Empire’s population (perhaps as much as ten percent). 
The Roman general
Pompey in his eastern campaign established the Roman province of Syria in 64 BC and conquered Jerusalem in 63 BC. Julius Caesar conquered Alexandria c. 47 BC and defeated Pompey in 45 BC. Under Julius Caesar, Judaism was officially recognised as a legal religion, a policy followed by the first Roman emperor, Augustus. Herod the Great was designated ‘King of the Jews’ by the Roman Senate in c. 40 BC, the Roman province of Egypt was established in 30 BC, and Judea proper, Samaria and Idumea (biblical Edom) were converted to the Roman province of Iudaea in 6 AD. Jewish–Roman tensions resulted in several Jewish–Roman wars, 66–135 AD, which resulted in the destruction of Jerusalem and the Second Temple and institution of the Jewish Tax in 70 and Hadrian‘s attempt to create a new Roman colony named Aelia Capitolina c. 130.
Around this time,
Christianity developed from Second Temple Judaism. In 313, Constantine and Licinius issued the Edict of Milan giving official recognition to Christianity as a legal religion. Constantine the Great moved the Roman capital from Rome to Constantinople (‘New Rome’) c. 330, sometimes considered the start of the Byzantine Empire, and with the Edict of Thessalonica in 380, Christianity became the state church of the Roman Empire. The Christian emperors persecuted their Jewish subjects and restricted their rights.  Some interesting links to share with you guys!
