The Mergui Family

The first figure whom the archive attaches with certainty to the Mergui lineage is named Jacob Mergui. Born in Morocco, he began his career as a rabbi in Meknès, one of the four imperial cities of the Sharifian kingdom, home to one of the oldest Jewish communities in the country. Meknès harbored for centuries an active mellah, a Jewish quarter organized around its synagogues, schools, and charitable institutions — a microcosm of Moroccan Jewish life where the families of Toshavim (indigenous residents) and the descendants of Megorashim (Spanish exiles who arrived after 1492) coexisted, not without tensions. It was in this environment that Jacob Mergui entered into his vocation.

In Meknès, he took direction of the Ozar HaTorah school. This institution, a Jewish educational network founded on an international scale after the Second World War to maintain Jewish education in communities in peril, held considerable importance in Morocco: it welcomed children whose families sought to reconcile modernity with fidelity to tradition. Leading such a school entailed a double responsibility — pedagogical toward the children, spiritual toward the entire community. What Jacob Mergui exercised there was not a mere job: it was a form of community service that would mark his entire subsequent trajectory.

Morocco in those years was transforming at great speed. Independence was proclaimed in 1956; King Mohammed V, whose benevolence Moroccan Jews had experienced under the Vichy occupation, died in 1961. The testimony of Fanny Mergui, another member of the diaspora bearing this surname, illustrates the upheaval of those years: having left Casablanca for Israel in 1961, this woman never ceased to fight so that the Jewishness of Morocco would not be forgotten — so that it would be known that the history of Moroccan Jews was also the history of the country. This conviction — that memory is a civic duty as much as a religious fidelity — was found in Jacob Mergui, who would transport to France not only his family but the project of an entire community.

The departure toward France — like that of tens of thousands of Moroccan Jewish families — was not a break with Judaism but, paradoxically, an occasion to redeploy its structures. Jacob Mergui did not leave Meknès to disappear into French citizenship: he arrived there to build.

Onomastic documentation also locates the Mergui lineage in Oran, that region of western Algeria which, throughout the nineteenth century, became one of the principal lands of welcome for Moroccan Jewish families. The patronym appears in the excerpts of Maurice Eisenbeth, with three orthographic variants recorded in his dictionary — a reflection of the multiple transcriptions to which a name lent itself when passed from Arabic and Hebrew scripts to the forms of French colonial administration.

To understand what this Oran presence signifies, one must enter the world that Eisenbeth restored with unprecedented precision. Maurice Eisenbeth (1886–1957) was Chief Rabbi of Algiers when he published, in 1936, The Jews of North Africa: Demography and Onomastics, at the Printing Press of the Lycée of Algiers, with the financial support of the General Government of Algeria. The work constituted the continuation of an earlier essay published in Constantine in 1931, North African Judaism, devoted then to the Jews of Constantine department alone. The request of several personalities and scholars that his research be extended to all of French North Africa gave birth to this second volume, considered since then as the first systematic study of the Jewish populations of Morocco, Algeria, Tunisia, and Libya, founded jointly on French, Spanish, and Italian colonial censuses, and on a methodical examination of patronyms.

The method that Eisenbeth describes in his preface is of remarkable rigor for the era. For Algeria, he proceeded to the "complete examination of the nominal lists of the inhabitants of all municipalities of Algeria," cross-referenced with the censuses of the General Government published from 1931 onward. In this work, he took into account principally "patronyms, masculine and feminine given names, professions, etc.," and in doubtful cases proceeded to supplementary inquiries.

This painstaking work revealed a painful paradox: legal integration had, statistically, rendered the Jews invisible. The Crémieux Decree of October 24, 1870, had declared "French citizens the indigenous Israelites of the departments of Algeria," incorporating them "ex officio to the nation, from the points of view at once ethnic and civil." The majority of the Algerian Jews of 1930, no longer being the direct beneficiaries of this act but their descendants, had declared themselves "French of origin" in the censuses. The number of Israelites recorded was, municipality after municipality, "manifestly inferior to reality". The Chief Rabbi himself noted that in "the Constantine agglomeration, where nonetheless resides one of the most numerous Israelite Communities of Algeria, 653 units alone responded: Israelite" — a figure that every observer knew to be far below reality.

Official statistics thus absorbed the Jews into the general category of citizen. Onomastics became then the only available archive: to make the patronym itself a document, to retain the name where the census had renounced. That the name Mergui appears in this inventory is not a procedural detail — it is the proof that the family was sufficiently established and identifiable to merit being saved from statistical oblivion. In a context where the services of the General Government themselves admitted their powerlessness to discriminate the Israelites in the forms, the fact that Eisenbeth retrieved the name through the nominal lists, the professional registers, and characteristic given names testifies to an ancient and rooted presence in Oran space.

This double presence — in Morocco and in Oran — delineates the vital space of a family of the Western Mediterranean. It reflects the great movement which, throughout the nineteenth century, led numerous Moroccan Jewish families to cross the Algero-Moroccan border to settle in Oran, Tlemcen, Sidi Bel Abbès, and in the cities of western Algeria. This movement did not occur in rupture but in continuity: families crossed the border while maintaining ties with their communities of origin, maintaining merchant and family networks that spanned administrative borders. For the Mergui, this bipolar network constituted at once a system of security and an economic spring.

In these communities of Oran and Morocco, families such as the Mergui became integrated into the dense fabric of a laborious Judaism, organized around the synagogue, charitable confraternities, and rabbinical courts. The communal registers that Eisenbeth examined for his inquiry contained not only civil records, but traces of rabbinical decisions, marriage contracts drawn up according to the forms of halakha, wills expressed in the language of tradition. Each entry in these registers was, by implication, a testimony to the continuity of an organized Jewish life.

The kehillah — the sense of community, that conviction that one does not save oneself alone — was the cardinal virtue of these circles. Economic activity, commerce, craftsmanship, and trade were not separated from religious life: they constituted its material foundation, enabling the maintenance of charitable institutions on which the poorest depended. The conception of Jewish Law irrigated every act of existence. Respect for halakha, fidelity to the commandments transmitted from generation to generation, outlined an art of living where piety was not an abstraction but an embodied practice — a practice that Maghrebi Judaism has always held in high esteem.

What also characterizes this space is the coexistence of two traditions within Moroccan Judaism: that of the Toshavim, indigenous families whose settlement in Morocco preceded Islam, and that of the Megorashim, descendants of those expelled from Spain who arrived after 1492, who brought with them the Sephardic customs of Iberia and a certain idea of intellectual and spiritual grandeur. This encounter enriched a singular Moroccan Jewish culture, both deeply rooted in its soil and open to external currents. It was in this synthesis that the Mergui family drew its formation.

In the context of Algerian Oran, an additional layer was added: French citizenship, granted by the Crémieux decree of 1870, inserted Jews into the Republic while keeping them active members of their communities. This dual belonging — French and Jewish, civic and religious — was never experienced as a contradiction by the families themselves. It became one, brutally, under Vichy.

In refusing to abandon its surname in the great colonial mixing, in continuing to call itself Mergui in Oran as in Fès, the family exercised without theorizing it that form of humility and memory that Judaism names zakhor — remember. To bear the name of one's fathers and transmit it to one's children was an act of fidelity as much as a matter of civil record.

The twentieth century imposed on North African Jews trials of unprecedented intensity. In Algeria, the Crémieux Decree of 1870 had made native Jews French citizens; this citizenship was brutally revoked under the Vichy regime in October 1940, plunging communities into legal destitution and persecution. The families of Oran, where bearers of the name Mergui were established, suffered the full force of this regression — exclusion from schools, professions, public life — before the Allied landing of November 1942 and the gradual restoration of rights closed this chapter of infamy.

There is a cruel irony in this history. Algerian Jews had answered "French by origin" in the censuses of the 1930s because the Crémieux Decree authorized it and assimilation was sincere. It was this very integration that Vichy turned against them. The archives that Eisenbeth had examined a few years earlier took on a wholly different meaning in retrospect: he had saved from oblivion the names of a community that was about to be stripped of its rights precisely because it bore these names. The lists of names he had combed through municipality by municipality became, retroactively, an act of preventive resistance to erasure.

In this trial, the virtue most clearly expressed by these communities was solidarity — tsedaka understood not as charity but as justice distributed and care given to the other. Networks of mutual aid, relief funds, reciprocal welcome made it possible to endure the dark years without the communal bond breaking. It was this solidarity, forged in adversity, that perhaps constituted the most enduring legacy of those years.

Then came, in the 1950s and 1960s, the great departure. The independence of Morocco in 1956 and that of Algeria in 1962 caused the exodus of nearly all North African Jews, scattered toward France, Israel, and the New World. The Mergui lineage followed this dual movement. On the Algerian side, it was a total and often painful break: one did not return, houses were abandoned, synagogues left behind. On the Moroccan side, the departure was more gradual — Fanny Mergui, who left Casablanca for Israel in 1961, embodied that generation which chose aliyah while refusing amnesia: her struggle, to the very end, was to bear witness to Moroccan Jewry, to make known that the history of Moroccan Jews was also the history of the country.

For Jacob Mergui, who had rooted his vocation in Meknès, the departure toward France did not signify the end of communal service, but its displacement. What he had learned in Meknès — to build, to teach, to sustain a community — he was going to put into practice in Montrouge.

Among the acts that the archive attaches with certainty to the Mergui lineage, none is more concrete than the founding of the consistorial community of Montrouge by Rabbi Jacob Mergui. Having arrived in France after his years in Meknès, where he had directed the Ozar HaTorah school and trained in the dual responsibility of educator and pastor, Jacob Mergui made the Hauts-de-Seine commune his new field of action. He founded the community there some forty years ago — that is, in the 1980s, precisely when the Jews of North Africa, settled in France for one or two decades, were seeking to reconstitute the communal structures that the exodus had scattered.

The community's synagogue opened its doors in 1988. Before that date, the community narrative reports, people prayed in a corrugated metal shed — an image that conveyed better than any lengthy analysis the tenacity of those who refused to wait for ideal conditions to maintain religious life. Then came, in 1993, the creation of the Yaguel Yaacov primary school — a Hebrew name paying homage to Jacob himself — the first primary school of the consistorial type. Today gathering some two hundred students, it embodies Jacob Mergui's profound conviction: that the transmission of Jewish culture and knowledge passes first through the school, and that this transmission is a collective responsibility that cannot be abandoned to individual initiative.

This choice to open a primary school rather than to settle for a synagogue merits attention. It reveals a conception of communal life that does not separate worship from education, prayer from knowledge. In Jewish tradition, study — talmud Torah — is not an accessory to religious life: it is its heart. Jacob Mergui, in founding both a synagogue and a school in Montrouge, was reconstructing the two pillars of the kehillah as he had known it in Meknès. The continuity is striking: from the Ozar HaTorah school in Morocco to the Yaguel Yaacov school in Hauts-de-Seine, it is the same gesture — to educate, to transmit, to anchor.

Jacob Mergui never ceased to invest himself in the education of young people. He also taught at the Maimonides school in Boulogne-Billancourt, perpetuating that concern for transmission that Jewish tradition places among the most imperative duties of a father and a master. His close ones spoke of "the poetry of his texts before the festivals" and his "warm humor" — a way of saying that his way of teaching was also a way of being, that piety in him was not austerity but generosity. He passed away on 25 Adar II 5782 — that is, 28 March 2022 in the civil calendar — leaving behind him a standing community, a living school, and a son who became one of the major figures of French Judaism.

Joël Mergui, son of Jacob, is a dermatologist by profession. This detail — a physician heading French institutional Judaism — is not insignificant: it says something about the place that contemporary French Judaism accords to committed lay members, to those men who, without being rabbis, devote a considerable part of their lives to the service of the community. It is within this tradition of community notables — that of the parnas, the benevolent administrator who puts his expertise at the service of the collective — that Joël Mergui stands.

He has presided over the Consistoire de Paris since 2006, and was president of the Consistoire central israélite de France from 2008 to 2021. Re-elected in 2021 for a fourth term at the head of the Consistoire de Paris — following a slate that won twelve of the thirteen seats to be filled — he thus directs the structure that manages the religious affairs of Europe's largest Jewish community. In March 2013, he accompanied President François Hollande on his official visit to Morocco, a symbolically powerful presence for a man whose roots lie precisely there — a way of materializing, on the diplomatic stage, the link that Jews of Moroccan origin maintain with their country of origin.

The Consistoire, an institution created under Napoleon to organize Israelite worship in the Republic, has embodied since its founding this ambiguous yet fruitful relationship between Judaism and the French state: an official organization of the Jewish community, recognized by public authority, but also charged with preserving the internal structures of worship. For Joël Mergui, heir to a lineage that came from Morocco via Meknès and arrived in France through educational and community engagement, to assume the presidency of this institution is to fully inhabit the two belongings — French and Jewish — that his ancestors had experienced, in Oran or Morocco, without ever opposing them.

In his writings and public statements, Joël Mergui has emphasized the central role of the family unit and faithfulness to traditions as the foundation of Jewish continuity. He has underscored the role of mothers, "attentive and passionate guardian of Judaism," this family priesthood exercised daily — a meditation on the domestic transmission of faith that condenses an essential value: piety as concrete faithfulness, woven into ordinary gestures rather than proclaimed in official chambers.

The circle is striking. Maurice Eisenbeth, Grand Rabbi of Algiers, had obtained for his 1936 survey a subsidy from the French Government-General of Algeria — which meant that the French Republic was financing itself the inventory of a community whose specificity it also sought, in its statistics, to dissolve. The consistorial institution had embodied since Napoleon this same paradox. For Joël Mergui, the child of Jacob Mergui and the descendant of the families who populated Eisenbeth's nominal lists, to assume the presidency of this institution is to transform into active heritage the constitutive tension of two centuries of Jewish history in France.

It would be a betrayal of the honesty of this book not to reserve a place for what onomasticians have said about this name itself — not to make it the entry point of the narrative, since the facts preceded it, but because the question of patronymic origins belongs to the history of the family just as much as the deeds of its members.

The Mergui surname belongs to the universe of North African Jewish names whose systematic inventory was first constituted by Eisenbeth's inquiry. Three orthographic variants were recorded — a reflection of the multiple transcriptions to which a name passed from Hebrew and Arabic to the graphies of colonial French administration. This graphic plurality is not an anomaly: it is the very signature of Maghrebi Jewish names, shaped by centuries of linguistic coexistence between Arabic, Berber, Judeo-Spanish, and French.

The interpretation of meaning divides the sources. The Moroccan tradition recorded in Dafina proposes an Eastern toponymic origin: the name would derive from Mragha — Maragha — the former capital of Azerbaijan in Arabic. This hypothesis, transmitted rather than established, speaks in its own way to the diasporic consciousness of a lineage that remembers coming from elsewhere, from a distant Orient whose memory it carried across the centuries and continents [Les Noms des Juifs du Maroc, Dafina]. Other readings connect the family to a Judeo-Mediterranean fund more difficult to circumscribe. These divergences, far from weakening the entry, illustrate a truth of Sephardic onomastics: a single name can bear several superposed memories.

The great subsequent repertories, notably those of Joseph Toledano, showed how North African surnames condense a geography of displacement — from the Eastern basin to the Atlantic confines. In this patient work of collection one reads a virtue that the lineage shares with all of Israel: the refusal of forgetting, the care taken in transmitting even the name, which is the smallest and most tenacious of archives [Une histoire de familles : les noms de famille juifs d'Afrique du Nord].

Eisenbeth's undertaking takes on a particular resonance here. His 1936 work had not only a scientific value: it had a prophylactic value. In combing through the nominative lists of all Algerian municipalities, the Grand Rabbi of Algiers constituted an archive parallel to the official civil register — an archive that would resist where the administration would cease to see. That this archive was published in 1936, four years before the abrogation of the Crémieux decree by Vichy, confers upon it retroactively a memorial importance that its author could not entirely foresee. The names he had saved from statistical erasure would soon have to resist an erasure of an entirely different nature.

What one can affirm is that the Mergui families scattered throughout the world bear this name today without necessarily knowing that Maurice Eisenbeth had once inscribed it in his columns, nor that tradition had attached to it the memory of an Azerbaijani city of which most have never heard. Yet it is in this very gap — between explicit memory and incorporated memory — that the strength of the name resides. One does not remember everything one carries; one carries it nonetheless.

Jacob Mergui (birth dates unknown — † March 28, 2022) — in Hebrew: Yaakov Mergui

Born in Morocco, Jacob Mergui built his rabbinical vocation in Meknès, where he directed the Ozar HaTorah school before migrating to France. He was the architect of the Consistory community of Montrouge (Hauts-de-Seine), laying its foundations some forty years ago. Under his leadership, the synagogue opened in 1988 and the Yaguel Yaacov primary school in 1993 — the first primary school of Consistory type, today counting approximately two hundred students. He also taught at the Maimonides school in Boulogne-Billancourt. Father of Joël Mergui, he left the image of a patient builder, attentive to education as much as to prayer, whose humor and generosity marked those close to him as much as his institutional work.

Joël Mergui (born circa 1961)

Son of Rabbi Jacob Mergui, a dermatologist by profession, Joël Mergui is the most eminent public figure of the lineage at the turn of the 21st century. He has presided over the Consistory of Paris since 2006 — reelected for a fourth term in 2021 — and was president of the Central Consistory of French Jewry from 2008 to 2021, thus leading the representative body of institutional Judaism in France. Originally from Morocco, he accompanied President François Hollande in March 2013 on his official trip to Morocco. In his writings, he has pursued rigorous reflection on family transmission and fidelity to Judaism as daily practice, not as abstract belonging.

Fanny Mergui (birth dates unknown — death dates unknown)

Bearing the same surname, Fanny Mergui belongs to the wave of Moroccan Jews who chose aliyah: she left Casablanca for Israel in 1961, at the moment when the Jewish community of Morocco was beginning its mass exodus. Engaged in Zionist movements before her departure, she never ceased to work to ensure that the memory of Moroccan Jewishness be preserved and recognized, bearing witness that the history of the Jews of Morocco was also the history of the country. Her figure illustrates the branch of the Mergui diaspora that opted for Israel rather than France.

Maurice Eisenbeth (1886–1957) — Grand Rabbi of Algiers

Without belonging to the Mergui lineage, Maurice Eisenbeth is inseparable from this book: his onomastic dictionary of 1936, The Jews of North Africa: Demography and Onomastics, published in Algiers at the Lycée Press, constitutes the main source thanks to which the Mergui surname, with its three orthographic variants, is documented in the communities of Oran. Grand Rabbi of Algiers, scholar and administrator, he carried out the first systematic inventory of Jewish populations in North Africa, by cross-referencing colonial censuses, rabbinical registers and name lists, thus saving from statistical erasure thousands of families that the Crémieux decree had merged into the general category of French citizen.

From Meknès to Montrouge, from the Moroccan mellah to the institutions of French Judaism, the Mergui lineage traces an exemplary trajectory of North African Jewish destiny: that of a family which managed, through migrations and ordeals, not only to preserve its identity but to place it at the service of others. The archival record establishes its contours from nineteenth-century Oran, where the surname appears in Eisenbeth's compilations; family memory extends it to Meknès, where Jacob Mergui found his vocation; contemporary sources carry it to the Paris Consistoire, where Joël Mergui has held a leading position for fifteen years.

What the principal documentary source of this book — Maurice Eisenbeth's foundational work published in Algiers in 1936 — illuminates with precision is the constitutive tension in which the lineage lived throughout the nineteenth and first twentieth centuries: between a claimed French citizenship and a Jewish belonging experienced within communal structures, rabbinical registers, and the surnames themselves. This tension, which Vichy momentarily converted into tragedy, was never experienced as a contradiction by the families. It was the very condition of their capacity to rebound: bearers of a double identity, they were never reduced to one or the other.

If one had to name, among all others, the virtue that this lineage best expressed, it would be involvement in collective life — that sense of communal service which, from the synagogue of Meknès to the school of Montrouge, from the direction of Ozar HaTorah to the presidency of the Consistoire, is transmitted like an inheritance more durable than the places themselves. Jacob Mergui built what his son administered; Joël Mergui presides over what his father prayed in. But behind this involvement in collective life appears a twin virtue, more discreet and perhaps even more fundamental: the refusal to forget — the conviction, shared by Eisenbeth when he compiled his lists and by Fanny Mergui when she testified from Israel, that remembering is already a form of action, that transmitting a name is already an act of resistance.

By embodying these two virtues — serving the community and preserving its memory — the Mergui lineage participates in a cardinal value that Israel carried through all its exiles: the conviction that the righteous does not save himself alone, that fidelity is proved in the care given to the other, and that zakhor — remember — is not a retrospective injunction but the foundation of all present action. The name, with its multiple spellings and its memory contested between the Azerbaijan of claimed origins and today's Hauts-de-Seine, remains the faithful witness to this long endurance.
