Arabization and Survival

The Christians of al-Andalus did not vanish in a single blow; they were drawn, generation by generation, into the language, dress, names, and prestige culture of Umayyad Córdoba, and the community that lived around Laura of Córdoba (died 864) was already losing its young to Arabic letters and to Islam. This file traces the process — the cultural pull famously lamented in Albarus’s Indiculus Luminosus (854), the slow drain of conversion (for which Richard Bulliet’s “conversion curve” is the standard framework), and the long contraction by emigration north and by deportation under the Almoravids and Almohads — and reads the martyr movement, and Laura within it, as a hard reaction against that assimilation.

Tradition: Pre-Schism Western (Mozarabic) / Orthodox reception

The Cultural Pull

By the mid-ninth century the Christians of Córdoba were being absorbed culturally into the world of their Muslim rulers. The pull was strongest where it always is — among the young, the urban, and the upwardly mobile, the elite families whose sons sought careers in or near the Umayyad administration. They adopted Arabic as their working and literary language, took Arabic names and Arabic dress, and prized the prestige learning of the court: its poetry, its rhetoric, its philosophy (Jessica A. Coope, The Martyrs of Córdoba: Community and Family Conflict in an Age of Mass Conversion, Lincoln, 1995). This acculturation is exactly what the term Mozarab — from Arabic musta’rib, “Arabized” — preserves: a Christian who has become Arab in culture while remaining Christian in faith. For the texture of that bilingual, increasingly Arabized Christianity, see christianity-in-al-andalus.md.

The locus classicus for this complaint is the Indiculus Luminosus, written in 854 by Paulus Albarus (Álvaro of Córdoba), the lay friend and biographer of the priest Eulogius and a defender of the martyrs (Kenneth Baxter Wolf, Christian Martyrs in Muslim Spain, Cambridge, 1988; Wolf, ed. and trans., The Indiculus luminosus of Paul Alvarus, Translated Texts for Historians 84, Liverpool, 2024). In its most-quoted passage Albarus turns from polemic against Islam to a bitter lament over his own community’s youth. In the standard older translation, he writes:

“The Christians love to read the poems and romances of the Arabs; they study the Arab theologians and philosophers, not to refute them, but to form a correct and elegant Arabic. Where is the layman who now reads the Latin commentaries on the Holy Scriptures? … Alas! all talented young Christians read and study with enthusiasm the Arab books; they gather immense libraries at great expense; they despise the Christian literature as unworthy of attention. They have forgotten their own language. For every one who can write a letter in Latin to a friend, there are a thousand who can express themselves in Arabic with elegance, and write better poems in this language than the Arabs themselves.”

The wording above follows the long-current English rendering of the passage (deriving from R. P. A. Dozy’s nineteenth-century translation and reproduced in countless surveys); the underlying text is Indiculus Luminosus §35, and Wolf’s 2024 Liverpool edition gives the current scholarly translation directly from the Latin. What the passage attests beyond doubt is that Albarus, writing in 854 as a partisan of the martyrs, saw the Arabization of Christian youth as a crisis — and that he wrote in Latin precisely because that Latinity was failing. As one modern commentary observes, it was a “futile attempt to stem the surging tide of Arabization.” His witness is rhetorical and one-sided — he is denouncing, not surveying — but it is the earliest and sharpest articulation of the assimilation anxiety that scholars now read as the background of the whole martyr movement.

Arabization and the Martyrs: Coope’s Reading

It is this engine — the absorption of Christians into Arab Muslim culture — that drives Jessica Coope’s influential interpretation of the Córdoba martyrdoms as a response to assimilation anxiety. On her reading the public denunciations of Muhammad were a way of redrawing a hard confessional line precisely where it was dissolving, the cutting edge of a faction resisting absorption (Coope, 1995). The competing readings — Wolf’s literary-critical account of the deaths as voluntary “radical” martyrdoms recast by Eulogius, Cutler’s missionary-provocation thesis, Christys’s source-skepticism — are set out, without adjudication, in the-historiographical-debate.md and at greater length in the-cordoba-martyrs-in-scholarship.md. Here the point is narrower: Albarus’s lament supplies the documentary ground on which Coope’s “age of mass conversion” rests, and Arabization is the historical condition the martyrs are read as reacting against.

Conversion to Islam

Cultural Arabization was not the same thing as apostasy, but it ran alongside it and smoothed its path. Conversion to Islam in al-Andalus was gradual at first and accelerating later, driven by the ordinary incentives of a society in which Islam was the religion of power, advancement, and lower taxation: the dhimmi paid the jizya and lived under disabilities the convert escaped (Coope, 1995; Ann Christys, Christians in al-Andalus, 711–1000, Richmond, 2002). Mixed marriage was an especially efficient solvent. Under Islamic law a Muslim man might marry a Christian woman, but their children were Muslims; the line between communities thus leaked steadily in one direction, and over generations the Christian population was drained from within (Coope, 1995). The martyr-records register this directly: several of the Córdoban martyrs were the children of mixed marriages or of converts, raised legally Muslim and then charged with apostasy when they professed Christ — the apostasy charge itself a fossil of the very intermarriage that was depleting the community (Coope, 1995; Wolf, 1988).

The standard framework for quantifying this slow attrition is Richard W. Bulliet’s “conversion curve” (Conversion to Islam in the Medieval Period: An Essay in Quantitative History, Cambridge, Mass., 1979). Bulliet plotted the appearance of distinctively Muslim names in biographical dictionaries across the Islamic world and found, for region after region, an S-shaped curve: slow conversion at first, then a rapid mid-phase of “mass conversion,” then a tapering as the population approached a Muslim majority. Applied to al-Andalus, his model places the steep, majority-making phase of conversion in the tenth century — that is, largely after the martyrs — with perhaps half the population Muslim only around the middle of that century. The framework is a model built on an onomastic proxy, not a census, and it should be held as such.

[Disputed: The timing and scale of conversion to Islam in al-Andalus are unsettled. Bulliet (Conversion to Islam in the Medieval Period, 1979), from the curve of Muslim names, dates the mass-conversion phase to the tenth century, with a Muslim majority reached only around 950 — implying that the ninth-century martyrs lived in a still-largely-Christian population whose absorption lay ahead. Critics question both the method and the result. Alwyn Harrison (“Behind the Curve: Bulliet and Conversion to Islam in al-Andalus Revisited,” Al-Masāq 24, 2012) argues that the curve has been widely misread, that the Andalusi data are exceptionally thin, and that — read as Bulliet’s own figures actually run — they warrant reconsidering the nature and length of Christian survival rather than supporting the confident “mass conversion” chronology often attributed to him. More broadly, scholars note the curve’s reliance on an elite, urban, name-based proxy and the difficulty of converting names into population shares at all (Christys, 2002, on the weakness of the record). Some would push significant conversion earlier; others doubt the quantitative exercise can settle the question. This collection presents Bulliet’s curve as an influential model, not an established fact.]

Survival and Decline

The Mozarabic community did not collapse with the martyrs; it persisted for centuries, but it contracted along three lines. The first was conversion, the slow demographic drain described above. The second was emigration northward: across the long Reconquista, Christians moved from al-Andalus into the Christian kingdoms — Asturias-León, Castile, Aragon, the Catalan counties — where Mozarabic refugees and their descendants became an influential element, carrying southern liturgy, law, and learning with them (Christys, 2002). The flow was old and steady, a release valve for a community under pressure.

The third line was outright persecution, and it came late and hard with the Berber dynasties from North Africa. The relatively accommodating order of the Umayyad emirate and caliphate gave way, after 1086, to the Almoravids, and after the 1140s to the still more rigorist Almohads. Under the Almoravid emir Ali ibn Yusuf, the great deportation of 1126 shipped many thousands of Mozarabs from the south — Granada, Córdoba, Seville — to Morocco, settling them around Meknes and Salé. The trigger was political: Mozarabs of Granada had appealed to and aided Alfonso I “the Battler” of Aragon during his deep raid into al-Andalus in 1125–1126, and the authorities, acting on a juridical ruling, treated this as a breach of the dhimma pact (Christys, 2002; and see the discussion of dhimmi status in al-Andalus). Critically, the deportees were forbidden to migrate north to the Christian kingdoms — the old escape route was closed. The Almohads who followed were harsher still, and by the later twelfth century the native Christian community of the Muslim south was effectively extinguished.

By the late Middle Ages, then, Mozarabic Christianity as a living community in the south had largely vanished — destroyed less by any single catastrophe than by the long compound of conversion, emigration, and finally deportation. What survived was cultural and liturgical: the Mozarabic Rite, the old Hispanic liturgy of the Visigothic and Mozarabic church, preserved and eventually printed at Toledo under Cardinal Cisneros (Missal and Breviary, 1502) and still celebrated in the Mozarabic Chapel of Toledo Cathedral. The faith outlived the community in the form of a rite.

This long Andalusi arc has a distant analogue in the much later experience of Eastern Christians under Ottoman rule — another centuries-long survival of a subordinated Christian population under Islamic law, with its own dynamics of conversion, accommodation, and martyrdom (see, comparatively, the Ottoman period).

The Martyrs Against Assimilation — and Laura

Read against this process, the martyr movement of 848–859 appears as a reaction against Arabization: a deliberate, costly re-drawing of the confessional boundary by a faction unwilling to let Christian identity dissolve into the prestige culture of the court. Albarus’s lament and the martyrs’ public blasphemies are two faces of one impulse — to make the line between Christian and Muslim visible and absolute precisely when intermarriage, conversion, and Arabization were erasing it (Coope, 1995; Wolf, 1988).

Laura belongs, in the logic of the tradition, to this resistance. Remembered as a widow who became a consecrated woman, an abbess at the convent of Cuteclara, and a martyr drowned in 864, she stands within the same Córdoban current of refusal — a Christian who chose death over the absorption that was carrying so many of her neighbors’ children into Islam. The thread must be held lightly: Laura died five years after Eulogius, beyond the contemporary corpus, and her own attestation is later and partly problematic (see who records Laura). What can be said is that the world of Arabization and survival described here is the world the tradition places her in, and the resistance to assimilation is the meaning the tradition gives her death.
