The development of Old French language and literature is a rich tapestry woven through centuries of linguistic evolution, cultural exchange, and political change. Its origins trace back to the Latin spoken in Roman Gaul, which was profoundly influenced by the Germanic tribes, especially the Franks, who settled in the region from the 5th century onward.
Origins and Early Influences
Latin, brought to Gaul by the Roman Empire, laid the foundation for the Gallo-Romance dialects that would eventually evolve into Old French. As Latin interacted with local Celtic languages and later with Germanic Frankish speech, it developed distinctive phonological and lexical features. For example, the Frankish influence introduced new vowel sounds, diphthongization, and stress patterns, which differentiated Old French from other Romance languages.
Transition from Latin to Old French
The gradual linguistic divergence from Latin was marked by the decline of Latin case endings and the simplification of complex Latin morphology. The spoken Latin in Gaul began to develop into a vernacular known as Vulgar Latin, which, over centuries, transformed into Old French by the late 8th to early 9th centuries. The earliest written records in Old French include the Serments de Strasbourg (842), a pivotal document that demonstrates the use of the language in official contexts, and the Sequence of Sainte Eulalie (c. 878), indicating the early literary use of Old French.
Regional Variations and Bilingualism
In early medieval France, especially in the north, Old French coexisted with other linguistic varieties, notably the langue d’oc (Occitan) in the south. In the North, the influence of Germanic languages created a dialectal divide with the Occitan-speaking South that persisted for centuries. This bilingual landscape contributed to the development of the langue d’oïl, the precursor to modern French, and influenced the orthography and phonology of Old French.
Occitan and the South
In the vibrant courts and bustling towns of medieval southern France, Occitan – known as langue d’oc – reigned as a language of poetry, law, and daily life. Occitan flourished as the vehicle of the troubadours, whose lyrical innovations in courtly love echoed across Europe.

The language’s prestige was such that it was spoken by royalty, including Eleanor of Aquitaine and her sons, Richard the Lionheart and King John of England. The cultural region of Occitania stretched from the Atlantic to the Alps, encompassing much of what is now southern France, as well as parts of Italy and Spain.
The Political Eclipse: Conquest and Centralization
The seeds of decline were sown with the gradual imposition of French royal authority over the south. The Albigensian Crusade (1209–1229), waged ostensibly against heresy, devastated the region and paved the way for northern (French) control. Over the next centuries, the kings of France consolidated their power, and the nobility and bourgeoisie of Occitania began to adopt French, while the peasantry largely retained Occitan. The process of linguistic shift began in the north and slowly crept southward.

The Ordinance of Villers-Cotterêts and the Rise of French
A decisive blow came in 1539 with the Ordinance of Villers-Cotterêts, issued by Francis I. This law mandated that all legal and administrative documents be written in French, not Latin or any other language. While its stated goal was to replace Latin, the effect was to marginalize Occitan in public life. French, the dialect of Paris and the north, became the language of power, law, and upward mobility, while Occitan was increasingly confined to the home and the countryside. It did survive there, however, with millions of speakers well into the Twentieth Century.
Literary Flourishing and Key Texts
The period from the 11th to the 14th centuries saw a remarkable growth in Old French literature, which became influential across Europe. Epic poems like the Chanson de Roland exemplify the chanson de geste genre, celebrating heroic deeds and serving as foundational texts for French literary identity. These works were often composed in the langue d’oïl dialect and drew inspiration from Latin models, blending oral storytelling traditions with written forms
Early Old French literature was heavily rooted in religious and heroic themes, with poetic forms inherited from Latin hymns and liturgical poetry. Over time, secular themes and courtly love emerged, leading to the proliferation of romances, lyric poetry, and allegorical texts.
Historical Context and Literary Growth
The increase in literacy and administrative needs from the 12th century onward spurred the production of written texts in Old French. The growth of urban centers, the influence of courtly culture, and the establishment of universities, notably in Paris, created a fertile environment for literary innovation. Political centralization under monarchs like Philip Augustus also promoted the use of French in official documents, further standardizing the language.

Old French’s influence extended beyond France, impacting other European literatures through translations and cultural exchanges. Its literary masterpieces, especially the chansons de geste and courtly romances, shaped the development of European epic and lyric traditions. In sum, the development of Old French was a dynamic process driven by linguistic contact, political consolidation, and cultural flourishing.
