The Song of Roland is an 11th-century chanson de geste based on the Frankish military leader Roland at the Battle of Roncevaux Pass in AD 778, during the reign of the Carolingian king Charlemagne. It is the oldest surviving major work of French literature. It exists in various manuscript versions, which testify to its enormous and enduring popularity in Medieval and Renaissance literature from the 12th to 16th centuries.

French is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to the French colonial empire, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French.
