 It seemed that the esoteric teachings of Kabbalah had found their "champion" and had triumphed, but this era of Jewish history unravelled when Zevi became an apostate to Judaism by converting to Islam after he was arrested by the Ottoman Sultan and threatened with execution for attempting a plan to conquer the world and rebuild the Temple in Jerusalem.Unwilling to give up their messianic expectations, a minority of Zevi's Jewish followers converted to Islam along with him.Many of his followers, known as Sabbatians, continued to worship him in secret, explaining his conversion not as an effort to save his life but to recover the sparks of the holy in each religion, and most leading rabbis were always on guard to root them out.
