The study surveys how Greek and Roman religious and racial concepts intersected with Jewish religion and society from the post‑exilic period through the Roman Empire, outlining internal Jewish developments under Persian and Hellenistic influence, Jewish communities in Egypt and Rome, the cultural pressures of Hellenization and the movements of resistance it produced, the role of Jewish missionary and polemical activity, social and philosophical divisions within Jewish life, outbreaks of revolt against imperial authority, and the evolving legal and communal status of Jews in the later empire.
