Izmir (Smyrna) under Byzantine and early Ottoman rule (until the 16th century) supported only a small Jewish community. The city's modern Jewish history begins with the 16th century Sephardic settlement, which transformed it rapidly into one of the most important Sephardic-Ottoman centers.
Acharonim
Izmir from the 17th through 19th centuries was a major Sephardic halachic and commercial center, serving as the principal Ottoman port of Levantine trade with Western Europe. Spanish-exile families (Palaggi, Yedid, Hazan, Benveniste) anchored the rabbinate. R. Chaim Benveniste (Knesset HaGedolah, Chief Rabbi 1660-1673), R. Eliyahu HaCohen (Shevet Musar, fled Aleppo for Izmir), R. Hayyim Palaggi (Chief Rabbi 1855-1868, with over 70 books to his name), and dozens of major poskim made Izmir one of the most-cited Sephardic centers of acharonic responsa. The community was also the epicenter of the catastrophic Sabbatean movement: Sabbatai Zvi (1626-1676) was born and active here. The Izmir community produced its own Hebrew printing presses from the 17th century, publishing major Sephardic responsa and homiletics.
Modern Era
Izmir's Jewish community in the late Ottoman and Turkish-Republican eras numbered around 35,000 at its peak. The community supported the famous Beit Israel synagogue complex, multiple Talmud Torah schools, and a vibrant Ladino press. The Population Exchange of 1923 and rising Turkish nationalism gradually pressured emigration; the 1948 establishment of Israel and the 1955 Istanbul pogrom (which spilled over) drove most of the community to Israel. Today perhaps 1,000 Jews remain, served by the historic Bikur Holim synagogue.
