Maghrebi Jews in the context of "Old Yishuv"

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 Sephardic 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'arabim.

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.

North African Sephardim are a distinct sub-group of Sephardi Jews, who descend from exiled Iberian Jewish families of the late 15th century and North African Maghrebi Jewish communities.

Since the creation of the state of Israel in 1948 and the Jewish exodus from Arab and Muslim countries, most North African Sephardim have relocated to either Israel, France, the US and other countries. Several Iberian Jewish families also emigrated back to the Iberian Peninsula to form the core of the Jewish community of Gilbraltar.

In Israel, Arabic is spoken natively by over 20 percent of the Israeli population, predominantly by Arab citizens of Israel, but also by Jews who arrived in Israel from Arab countries. Some refer to the modern Hebrew-influenced Levantine Arabic vernacular as the "Israeli Arabic dialect" or colloquially as Aravrit, a portmanteau of the Hebrew words Ivrit (lit. 'Hebrew') and Aravit (lit. 'Arabic').

Among Israeli Arabs in central Israel, the vernacular spoken is similar to Palestinian Arabic, while the Negev Bedouin traditionally speak their own dialect of Arabic. The dialects in the northern part of the country merge with southern Lebanese Arabic. Many first-generation Mizrahi Jews and Maghrebi Jews (i.e. those who made aliyah to Israel from the Arab world) can still speak Judeo-Arabic dialects, while their Israel-born descendants have overwhelmingly adopted Hebrew as their first (or sole) language.

Shmuel ibn Naghrillah (Hebrew: שְׁמוּאֵל הַלֵּוִי בֶּן יוֹסֵף, romanized: Šəmuʿēl HalLēvi ben Yosēf; Arabic: أبو إسحاق إسماعيل بن النغريلة, romanized: ʾAbū ʾIsḥāq ʾIsmāʿīl bin an-Naġrīlah), mainly known as Shmuel HaNagid (Hebrew: שמואל הנגיד, romanized: Šəmūʿel HanNāgid, lit. 'Samuel the Prince') and Isma'il ibn Naghrilla (993–1056), was a Jewish statesman, military commander, scholar, linguist and poet in medieval al-Andalus. He served as grand vizier of the Taifa of Granada, commander of its army in battle, and leader of the local Jewish community. Rising to unprecedented prominence in both Muslim and Jewish spheres, he became one of the most powerful and influential Jews in medieval Spain. He is also considered one of the greatest Jewish poets of all time.

Raised in Córdoba in a Jewish merchant family, Samuel received a broad education in Jewish law, astronomy, logic, and biblical exegesis. Following unrest in Córdoba, he settled in Granada, where he entered government service and quickly rose in rank. He led Granada's forces in battles against Seville, Carmona, and Christian mercenaries. He was a respected halakhic authority, talmudist, and philanthropist, supporting Jewish academies in Babylonia and North Africa and leading a Jewish academy in Granada. His relationships extended to towering Jewish intellectuals such as Solomon Ibn Gabirol Nissim Gaon of Kairouan. He was involved in the Hebrew grammar debates of his time, opposing Jonah Ibn Janah, and contributed to the development of medieval Hebrew philology.
