Zionism is the new term for Sabbateanism

The Sabbateans were a variety of Jewish followers, disciples, and believers in Sabbatai Zevi, 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.
