 The spiritual and mystical yearnings of many Jews remained frustrated after the death of Isaac Luria and his disciples and colleagues.No hope was in sight for many following the devastation and mass killings of the pogroms that followed in the wake of the Chmielnicki Uprising (1648–1654), the largest single massacre of Jews until the Holocaust, and it was at this time that a controversial scholar by the name of Sabbatai Zevi (1626–1676) captured the hearts and minds of the Jewish masses of that time with the promise of a newly minted messianic Millennialism in the form of his own personage.His charisma, mystical teachings that included repeated pronunciations of the holy Tetragrammaton in public, tied to an unstable personality, and with the help of his greatest enthusiast, Nathan of Gaza, convinced the Jewish masses that the Jewish Messiah had finally come.
