House of Valois-Burgundy
His ancestors of the French House of Valois-Burgundy over the centuries had acquired a collection of territories on both sides of the border of France with the Holy Roman Empire. It stretched from Burgundy proper in the south to the Low Countries in the north, somewhat resembling of early medieval Middle Francia. Upon the duke's death, King Louis XI of France attempted to seize his heritage as reverted fiefs but was defeated by Maximilian, who by the 1482 Treaty of Senlis annexed the Burgundian territories, including Flanders as well as French-speaking Artois and asserted the possession of the County of Burgundy (Franche-Comté).
