The Hellenistic Period

The Hellenistic period of Jewish history began in 332 BCE when Alexander the Great conquered Persia. Upon his death in 323 BCE, his empire was divided among his generals. At first, Judea was ruled by the Egyptian-Hellenic Ptolemies, but in 198 BCE, the Syrian-Hellenic Seleucid Empire, under Antiochus III, seized control over Judea.
The Near East was cosmopolitan, especially during the Hellenistic period. Several languages were used, and the matter of the lingua franca is still subject of some debate. The Jews almost certainly spoke Aramaic among themselves. Greek was at least to some extent a trade language in the region, and indeed throughout the entire eastern portion of the Mediterranean. Judaism was rapidly changing, reacting and adapting to a larger political, cultural, and intellectual world, and in turn drawing the interests of non-Jews. Historian Shaye Cohen observed:
All the Judaisms of the Hellenistic period, of both the diaspora and the land of Israel, were Hellenized, that is, were integral parts of the culture of the ancient world. Some varieties of Judaism were more hellenized than others, but none was an island unto itself. It is a mistake to imagine that the land of Palestine preserved a "pure" form of Judaism and that the diaspora was the home of adulterated or diluted forms of Judaism. The term "Hellenistic Judaism" makes sense, then, only as a chronological indicator for the period from Alexander the Great to the Macabees or perhaps to the Roman conquests of the first century BCE. As a descriptive term for a certain type of Judaism, however, it is meaningless because all the Judaisms of the Hellenistic period were "Hellenistic." (Cohen 1987: 37)
The Hellenistic Period saw the canonization of the Tanakh (Hebrew Bible), according to some theories, see Development of the Jewish Bible canon for details, and the emergence of extra-Biblical sacred traditions
