Old French (, , ; Modern French: ) was the language spoken in most of the northern half of France from approximately the 8th to the 14th centuries. Rather than a unified language, Old French was a linkage of Romance dialects, mutually intelligible yet diverse, spoken in the northern half of France. These dialects came to be collectively known as the , contrasting with the in the south of France. The mid-14th century witnessed the emergence of Middle French, the language of the French Renaissance in the Île de France region; this dialect was a predecessor to Modern French. Other dialects of Old French evolved themselves into modern forms (Poitevin-Saintongeais, Gallo, Norman, Picard, Walloon, etc.), each with its own linguistic features and history. The region where Old French was spoken natively roughly extended to the northern half of the Kingdom of France and its vassals (including parts of the Angevin Empire, which during the 12th century remained under Anglo-Norman rule), and the duchies of Upper and Lower Lorraine to the east (corresponding to modern north-eastern France and Belgian Wallonia), but the influence of Old French was much wider, as it was carried to England and the Crusader states as the language of a feudal elite and commerce. Areal and dialectal divisions The area of Old French in contemporary terms corresponded to the northern parts of the Kingdom of France (including Anjou and Normandy, which in the 12th century were ruled by the Plantagenet kings of England), Upper Burgundy and the duchy of Lorraine. The Norman dialect was also spread to England and Ireland, and during the crusades, Old French was also spoken in the Kingdom of Sicily, and in the Principality of Antioch and the Kingdom of Jerusalem in the Levant. As part of the emerging Gallo-Romance dialect continuum, the were contrasted with the (the emerging Occitano-Romance group, at the time also called Provençal), adjacent to the Old French area in the south-west, and with the Gallo-Italic group to the south-east. The Franco-Provençal group developed in Upper Burgundy, sharing features with both French and Provençal; it may have begun to diverge from the as early as the 9th century and is attested as a distinct Gallo-Romance variety by the 12th century. Dialects or variants of Old French include: Burgundian in Burgundy, then an independent duchy whose capital was at Dijon; Picard of Picardy and Romance Flanders, with Lille, Amiens and
