Burgundy (/ˈbɜːrɡəndi/ BUR-gən-dee, French: Bourgogne [buʁɡɔɲ] ; Burgundian: Bregogne) is a historical region in France, encompassing the territory of the former administrative region of the same name, that existed from 1982 to 2015, and was merged since 1 January 2016 into the newly created administrative region of Bourgogne-Franche-Comté, encompassing its western half. In historical terms, that region was formed as the Duchy of Burgundy, which existed between the 10th and the 18th century. During the late medieval and early modern periods, the region was of great political importance, being the core of the Valois-Burgundian State, and also becoming a focal point of diplomacy and courtly culture that set the fashion for European royal houses and their courts. The regional capital, Dijon, was wealthy and powerful, being a major European centre of art and science, and of Western Monasticism.
The modern Burgundy encompasses only the north-western parts of the ancient Kingdom of the Burgundians, that had much wider territorial scope. In 843, under the Treaty of Verdun, old Burgundian lands were divided, with all of north-western regions being assigned to the West Frankish Kingdom. Since the beginning of the 10th century, those regions were organized as the Duchy of Burgundy, remaining under the sovereignty of the Kingdom of France. Since 1004, the House of Burgundy, a cadet branch of the French royal House of Capet, ruled over the Duchy, that roughly conformed to the borders and territories of the later administrative region of Burgundy. Upon the extinction of the Burgundian male line the duchy reverted to the King of France and the House of Valois.
