Historical and cultural region, south-central France. Languedoc's name is derived from the traditional language of southern France, in which the word oc means yes (seeOccitan language). From 121 BC the region was part of the Roman province of Gallia Narbonensis. With the fall of the Roman Empire, it was controlled by the Visigoths in the 5th century. During the Middle Ages it came under the counts of Toulouse. Religious wars (seeAlbigensian Crusade) in the 13th century brought it under the French crown. From the 16th to 18th centuries Languedoc was the scene of Protestant persecution that culminated in the war of the Camisards. Protestant revolt led to its division into départments.
