Sabbatai Zevi (1626–1676)
converted to Islam in Ottoman Court possibly in exchange for amnesty in 1666, some of his followers followed him into Islam whiles others gave esoteric explanations and dismissals of his conversion. This group was followed by about 3,000 other Sabbateans in 1683, shortly after the death of
Nathan of Gaza, which occurred in 1680. Despite their outward conversion to Islam, the Sabbateans
secretly remained faithful to Judaism and continued to hold their
Kabbalistic theology, along with Jewish beliefs and rituals. Despite lingering suspicions throughout the 19th century that the Thessaloniki's Dönmeh were secretly Jewish, the group gradually evolved into a distinct heterodox Muslim sect, shaped in part by Sufi influences as their connection to Judaism faded. Wealthier Dönmeh families increasingly intermarried with mainstream Muslims and became integrated into Ottoman urban society. By the late 19th century, the Dönmeh were active in expanding Muslim education in Thessaloniki and played a significant role in the city's commercial, administrative, and intellectual life. Some became prosperous merchants, building European-style villas along the seafront and entering municipal governance, while others worked in skilled trades such as barbering, coppersmithing, and butchery. Their embrace of European education and reformist ideas helped turn Thessaloniki into one of the most progressive and politically dynamic cities in the Ottoman Empire. One of the leaders of the supposed
İzmir plot to assassinate President
Mustafa Kemal Atatürk in İzmir after the establishment of the
Turkish Republic was a Dönme named
Mehmed Cavid, a founding member of the
Committee of Union and Progress (CUP) and the former
Minister of Finance of the Ottoman Empire. Convicted after a government investigation, Cavid Bey was hanged on 26 August 1926 in
Ankara. After the foundation of the Turkish Republic in 1923, Atatürk's
Turkish nationalist policies, which had left
ethnic and religious minorities in the lurch, were accompanied by
antisemitic propaganda by nationalist publishers in the 1930s and 1940s. In 1923, during the compulsory population exchange between Greece and Turkey, the Dönme of Thessaloniki were classified as Muslims and relocated to Istanbul. There, a smaller but influential community emerged, including businessmen, newspaper publishers, industrialists, and diplomats, many of whom continued to thrive in Turkish society. ==Religious beliefs and practices==
