Philip was generally preoccupied with matters in his own territories and was seldom involved directly in the Hundred Years' War between England and France, although he did play a role during a number of periods, such as the campaign against Compiègne during which his troops captured Joan of Arc. He incorporated Namur into Burgundian territory in 1429 (by purchase, from John III, Marquis of Namur) and Hainault and Holland, Friesland and Zeeland in 1432 with the defeat of Jacqueline, Countess of Hainault, in the last episode of the Hook and Cod wars. He inherited the Duchies of Brabant and Limburg and the Margraviate of Antwerp in 1430 on the death of his cousin Philip of Saint-Pol and purchased Luxembourg in 1443 from Elisabeth of Bohemia, Duchess of Luxembourg.
