* Sabbatai Zevi (17th century): One of the most famous false Jewish Messiahs. He gained a massive following across the Jewish world. However, when faced with the Ottoman Sultan's choice between conversion to Islam or death, he converted. This conversion was a devastating blow to his followers and essentially a public "recantation" of his messianic claim, though not necessarily an admission of it being a lie on his part as much as a desperate act to save his life. Many of his followers were deeply disillusioned, while others continued to believe in him even after his conversion, developing complex theological explanations for his actions.
