query: When did the Romans conquer Jerusalem?
passage: History of the Jews in the Roman Empire
The 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).[1]
passage: Arab conquest of the Levant
Syria had been under Roman rule for seven centuries prior to the Arab Muslim conquest and had been invaded by the Sassanid Persians on a number of occasions during the 3rd, 6th and 7th centuries; it had also been subject to raids by the Sassanid's Arab allies, the Lakhmids. During the Roman period, beginning after the fall of Jerusalem in the year 70, the entire region (Judea, Samaria, and the Galilee) was renamed "Palaestina", subdivided into Diocese I and II. The Romans also renamed an area of land including the Negev, Sinai, and the west coast of the Arabian Peninsula as "Palaestina Salutaris", sometimes called "Palaestina III" or "Palaestina Tertia". Part of the area was ruled by the Arab vassal state of the Ghassanids' "symmachos". During the last of the Roman-Persian Wars, beginning in 603, the Persians under Khosrau II had succeeded in occupying Syria, Palestine and Egypt for over a decade before being forced by the victories of Heraclius to conclude the peace of 628. Thus, on the eve of the Muslim conquests the Romans (or Byzantines as modern Western historians conventionally refer to Romans of this period) were still in the process of rebuilding their authority in these territories, which in some areas had been lost to them for almost twenty years. Politically, the Syrian region consisted of two provinces: Syria proper stretched from Antioch and Aleppo in the north to the top of the Dead Sea. To the west and south of the Dead Sea lay the province of Palestine. Syria was mostly a Syriac and Hellenized land with some Jewish presence and with a partly Arab population, especially in its eastern and southern parts. The Syriac Christians, Jews and Arabs had been there since pre-Roman times, and some had embraced Christianity since Constantine I legalized it in the fourth century and moved the capital from Italy to Byzantium (renamed Constantinople), from which the name Byzantine is derived.
