What is "donmeh"

The Dönmeh were a group of crypto-Jews in the Ottoman Empire who converted publicly to Islam, but were said to have retained their beliefs. The movement was historically centred in Salonica. The group originated during and soon after the era of Sabbatai Zevi, a 17th-century Jewish kabbalist who claimed to be the Messiah and eventually converted to Islam in order to escape punishment by the Sultan Mehmed IV. After Zevi's conversion, a number of Jews followed him into Islam and became the Dönmeh. Since the 20th century, assimilated Dönmeh might have intermarried with other groups and most have assimilated into Turkish society.
