A parchment dated 7 September 1346 in Frankfurt, of which the seal is destroyed, announces that Louis IV of Bavaria, Emperor of the Holy Germanic Empire bestows for himself and his heirs, in the name of his spouse, the empress Margaret, to never cede, divide or bestow the counties of Hainault, Holland, Zeeland and the palatine of Frisia, which belong to his wife, Margaret II (of Avesnes), Countess of Hainault and to her heirs, excepting the rights of her sisters and after her death, to William (future William III, Count of Hainault) Duke (I) of Bavaria, and after his decease to Albert (future Albert I, Count of Hainaut) and later these passed to their son William V. Margaret's sisters, including Philippa of Hainault who was Queen consort of Edward III of England disavowed their hereditary claims.
