Musta'arabi Jews

Musta'arabi Jews (Arabic: المستعربين al-Mustaʿribīn "Mozarabs"; Hebrew: מוּסְתערבים Mustaʿravim) were the Arabic-speaking Jews, largely Mizrahi Jews and Maghrebi Jews, who lived in the Middle East and North Africa prior to the arrival and integration of Ladino-speaking Sephardi Jews of the Iberian Peninsula, following their expulsion from Spain in 1492. Following their expulsion, Sephardi Jewish exiles moved into the Middle East and North Africa (among other countries around the Mediterranean Basin), and settled among the Musta'arabi.

In many Arab countries, Sephardi immigrants and the established Musta'arabi communities maintained separate synagogues and separate religious rituals, but often had a common Chief Rabbinate. The general tendency, however, was for both the communities and their customs to amalgamate, adopting a mostly Sephardic liturgy. This pattern was found in most Musta'arabi communities in Arab countries. A typical example is in the history of the Jews in Syria.

In contrast, in Tunisia, there was a strong and enduring social distinction between Tuansa (the established Tunisian Jews) and L'grana (immigrant Livornese Jews from Italy to Tunisia).
