9th century there were three Burgundies: the Kingdom of Upper (Transjurane) Burgundy around Lake Geneva, the Kingdom of Lower Burgundy in Provence, the Duchy of Burgundy west of the Saône. The two kingdoms of Upper and Lower Burgundy were reunited in 933 as the Kingdom of Burgundy. This kingdom in turn was absorbed into the Holy Roman Empire under Conrad II in 1032, and known from the 12th century as the Kingdom of Arles. The Duchy of Burgundy was annexed by the French throne in 1004. During the Middle Ages, Burgundy was the seat of some of the most important Western churches and monasteries, among them Cluny, Cîteaux, and Vézelay. During the 12th and 13th centuries, the County of Burgundy emerged from the area previously within the Kingdom of Upper Burgundy. It became known as the Free County of Burgundy or Franche-Comté. During the Hundred Years' War, King John II of France gave the duchy to his youngest son, Philip the Bold, rather than leaving it for his successor on the French throne. Following a personal union between the Duchy and the County of Burgundy, the "Two Burgundies" soon became a major rival to the French throne. The Dukes of Burgundy succeeded in assembling an empire stretching from Switzerland to the North Sea, in large part by marriage. This Burgundian State consisted of a number of fiefdoms on both sides of the (then largely symbolic) border between the Kingdom of France and the Holy Roman Empire. Its economic heartland was in the Low Countries, particularly Flanders and Brabant. The Burgundian court outshone the French court both economically and culturally. In Belgium and in the south of the Netherlands, the expression "Burgundian lifestyle" is still used to denote enjoyment of life, good food, and extravagant spectacle. In 1477, at the battle of Nancy during the Burgundian Wars, the last duke Charles the Bold was killed in battle, and the Duchy itself was annexed by France. In the late 15th and early 16th centuries, the other Burgundian territories provided a power base for the rise of the Habsburgs, after Maximilian of Austria married the surviving daughter of the ducal family, Mary. After her death, her husband moved his court first to Mechelen and later to the palace at Coudenberg, Brussels, and from there ruled the remnants of the empire, the Low Countries (Burgundian Netherlands) and Franche-Comté, then still an imperial fief.
