have held that, beyond the few facts considered to be historically certain, certain other elements of Jesus' life are "historically probable". Modern scholarly research on the historical Jesus thus focuses on identifying the most probable elements. Judea and Galilee in the 1st century In AD 6, Judea, Idumea, and Samaria were transformed from a Herodian client kingdom of the Roman Empire into an imperial province, also called Judea. A Roman prefect, rather than a client king, ruled the land. The prefect ruled from Caesarea Maritima, leaving Jerusalem to be run by the High Priest of Israel. As an exception, the prefect came to Jerusalem during religious festivals, when religious and patriotic enthusiasm sometimes inspired unrest or uprisings. Gentile lands surrounded the Jewish territories of Judea and Galilee, but Roman law and practice allowed Jews to remain separate legally and culturally. Galilee was evidently prosperous, and poverty was limited enough that it did not threaten the social order. This was the era of Hellenistic Judaism, which combined Jewish religious tradition with elements of Hellenistic Greek culture. Until the fall of the Western Roman Empire and the Muslim conquests of the Eastern Mediterranean, the main centers of Hellenistic Judaism were Alexandria (Egypt) and Antioch (now Southern Turkey), the two main Greek urban settlements of the Middle East and North Africa area, both founded at the end of the 4th century BCE in the wake of the conquests of Alexander the Great. Hellenistic Judaism also existed in Jerusalem during the Second Temple Period, where there was conflict between Hellenizers and traditionalists (sometimes called Judaizers). The Hebrew Bible was translated from Biblical Hebrew and Biblical Aramaic into Jewish Koine Greek; the Targum translations into Aramaic were also generated during this era, both due to the decline of knowledge of Hebrew. Jews based their faith and religious practice on the Torah, five books said to have been given by God to Moses. The three prominent religious parties were the Pharisees, the Essenes, and the Sadducees. Together these parties represented only a small fraction of the population. Most Jews looked forward to a time that God would deliver them from their pagan rulers, possibly through war against the Romans. Sources New Testament scholars face a formidable challenge when they analyze the canonical Gospels. The Gospels are not biographies in the modern sense, and the authors explain Jesus' theological significance and recount his public ministry while omitting
