Abstract: This study explores the current situation of Istanbul Jewry—a small Jewish community within Turkey’s large Muslim majority. In particular, it focuses on the changes that have taken place in the languages spoken by the community over the last century, in order to explore the experiences of transformation and integration within a religious minority in Turkey. The political, cultural, and social causes of language change among Istanbul Jews raise questions related to identity, culture, belonging, assimilation, resistance, and equality. The study thus relates the history of Istanbul Jewry to theories of language change, diaspora, and collective memory, reflecting on data gathered through personal observation, in-depth interviews, and analysis of primary and secondary sources. The qualitative findings suggest that the use of a particular language (Ladino, French or Turkish) has meant different things to different generations: The older generations see themselves as distinct because of their Ladino heritage, accepting their marginal position in wider society and making no effort to change it. In contrast, the younger generation is better integrated, speaking no Ladino and seeing little difference between themselves and the rest of Turkish society. Nevertheless, the state, politicians and the majority of the Muslim population continue to reproduce a discourse of Jews’ outsider status, with which the younger generation must contend.
