In keeping with the policies of previous Capetian and Valois monarchs, Louis asserted the supremacy of the king within the territory of France. Over the course of the preceding centuries, and during the Hundred Years' War, the French kings effected an administrative unification of the country. Unlike Germany, which languished as a miscellany of feudal factions, France emerged from the Middle Ages as a centralized state. But this centralization was opposed by the League of Public Weal, whose nobles sought to restore their feudal prerogatives.
Charles the Bold, as heir to the duke of Burgundy, whose fiefs in France included Flanders, and who held the Imperial lands of Holland and Brabant, sought to make the Duchy of Burgundy independent of the French throne and aspired to forge it into a kingdom of his own between France and Germany stretching between the North Sea on the north and the Jura Mountains on the south; and from the Somme River on the west to the Moselle River on the east. This kingdom would restore the ancient kingdom of Lotharingia—approximating the former domains of the Frankish Emperor Lothair I.
