House of Valois-Burgundy
In 1363 the French king John II of Valois enfeoffed his youngest son Philip the Bold with the Duchy of Burgundy ("Bourgogne"). Philip in 1369 married Margaret of Dampierre, only child of Count Louis II of Flanders (d. 1384), whose immense dowry not only comprised Flanders and Artois but also the Imperial County of Burgundy. He thereby became the progenitor of the House of Valois-Burgundy who systematically came into possession of different Imperial fiefs: his grandson Philip the Good, Duke of Burgundy from 1419, purchased Namur in 1429, inherited the duchies of Brabant and Limburg from his cousin Philip of Saint-Pol in 1430. In 1432 he forced Jacqueline of Wittelsbach to cede him the counties of Hainaut and Holland with Zeeland according to the Treaty of Delft and finally occupied Luxembourg, exiling Duchess Elisabeth of Görlitz in 1443.
