The messianic claimant Shabbetai Tzvi rocked the Jewish world in the mid-17th century, counting perhaps half the Jews of Europe, North Africa, and the Middle East among his supporters. Though he is often treated as a footnote in Jewish history, his influence persisted for centuries after his conversion to Islam in 1666. In this episode, Gavin and Jordan discuss the story of Shabbetai Tzvi, tracing his legacy through the 18th and 19th centuries and into the present day.
