The Palestinian Amoraim (~200–400 AD) operated under conditions radically different from their Babylonian counterparts — living under Roman and then Byzantine Christian rule that became increasingly hostile as Christianity became the state religion. Key Palestinian academies: Tiberias (where Rabbi Yochanan bar Nappaha, ~180–279 AD, was the dominant figure and probably the editor of the Jerusalem Talmud), Sepphoris, and Caesarea. Rabbi Yochanan’s output was enormous: he is the most-cited authority in the Jerusalem Talmud and shaped its entire character. The Palestinian Talmud (Yerushalmi) differs from the Babylonian: it is less polished (editing was cut short, probably by the deteriorating conditions of Byzantine persecution), written in Palestinian Aramaic (vs Eastern Aramaic in the Bavli), and reflects different legal traditions and biblical interpretations. The Palestinian Amoraim also produced the great Midrash Rabbah collections — homiletical and narrative interpretations of the Torah and the Five Scrolls — which preserve older traditions and demonstrate the creative vitality of Palestinian Jewish culture even under pressure. The closure of the Palestinian academies (the Yerushalmi was essentially “abandoned” rather than formally closed, ~400 AD) reflects the harsh conditions of Jewish life under Christian Roman rule, including heavy taxation, legal disabilities, and periodic anti-Jewish legislation.
