Sabbatai Zevi, born on August first, sixteen twenty-six, was a prominent Jewish mystic and rabbi hailing from Smyrna, with roots tracing back to Romaniote Jews from Patras. He is best known for his controversial claim to be the long-awaited Jewish Messiah, which led to the establishment of the Sabbatean movement. Central to his teachings was the radical belief that during the Messianic Age, actions traditionally deemed sinful would be transformed into acts of righteousness. This antinomian doctrine encouraged Zevi and his followers to intentionally violate Jewish commandments, a practice that sparked significant debate and later inspired movements such as the Frankists.
In February of sixteen sixty-six, Sabbatai arrived in Constantinople, where he was swiftly imprisoned under the orders of the grand vizier, Köprülüzade Fazıl Ahmed Pasha. By September of the same year, after being shuffled between various prisons, he faced trial in Adrianople on charges of inciting sedition. The Grand Vizier presented him with a fateful choice: death or conversion to Islam. Zevi chose the latter, adopting an Islamic turban and receiving a generous pension from the Ottoman state for his compliance with their political and religious agenda.
This conversion led to a significant shift for Zevi and his followers, approximately three hundred families who also embraced Islam, becoming known as the Dönme, meaning 'converts' in Turkish. However, his life continued to be tumultuous; the Ottomans banished him twice, first within Constantinople and later to a small town now known as Ulcinj in modern-day Montenegro. Ultimately, Sabbatai Zevi spent his final days in isolation, far from the vibrant community that once surrounded him.
