Sabbateans

The Sabbateans (or Sabbatians) are a variety of Jewish followers, disciples, and believers in Sabbatai Zevi (1626–1676), an Ottoman Jewish rabbi and Kabbalist who was proclaimed to be the Jewish Messiah in 1666 by Nathan of Gaza.

Vast numbers of Jews in the Jewish diaspora accepted his claims, even after he outwardly became an apostate due to his forced conversion to Islam in the same year. Sabbatai Zevi's followers, both during his proclaimed messiahship and after his forced conversion to Islam, are known as Sabbateans.

In the late 17th century, northern Italy experienced a surge of Sabbatean activity, driven by the missionary efforts of Abraham Miguel Cardoso. Around 1700, a radical faction within the Dönmeh movement, led by Baruchiah Russo, emerged, which sought to abolish many biblical prohibitions. During the same period, Sabbatean groups from Poland migrated to the Land of Israel. The Sabbatean movement continued to disseminate throughout central Europe and northern Italy during the 18th century, propelled by "prophets" and "believers." Concurrently, anti-Sabbatean literature emerged, leading to a notable dispute between Rabbi Jacob Emden (Ya'avetz) and Jonathan Eybeschuetz. Additionally, a successor movement known as Frankism, led by Jacob Frank, began in Eastern Europe during this century. Part of the Sabbateans lived on until well into 21st-century Turkey as descendants of the Dönmeh.
