Encyclopaedia Britannica, 1981, Macropaedia, Vol XIV, p221, Philip II Augustus: "...Philip, on April 28, 1180, married Isabella, the daughter of Baldwin V of Hainaut and the niece (through her mother) of Philip of Alsace the count of Flanders, who promised to give the King the territory of Artois as her dowry.."

p179:  "William Clito's tenure of his countship was of but little more than a year, and a year filled with fighting. Boulogne was a vassal county ofFlanders; but the new count, Stephen, undoubtedly carrying out the directions of his uncle, refused him homage, and William endeavoured to compel his obedience by force. Insurrections broke out behind him, due in part to his own severity of rule; and the progress of one of his rivals who was destined to succeed him, Dietrich of Elsass (sic), was alarming. Louis attempted to come to his help but was checked by a forward move of Henry with a Norman army. The tide seemed about to turn in Henry's favour once more, when it was suddenly impelled that way by the death of William. Wounded in the hand by a spear, in a fight at Alost, he died a few days later...But for Henry this opportune death not merely removed from the field the mostdangerous rival for Matilda's succession, but it also re-established the English influence in Flanders. Dietrich of Elsass became count with the consent of Louis, and renewed the bond with England. Not long afterwards by the influence of Henryhe obtained as wife, Geoffrey of Anjou's sister Sibyl, who had been taken from William Clito."
p277:  "For some time after his return to England Henry was occupied, as he had been of late on the continent, with minor details of government of no permanent importance. The treaty of alliance with Count Dietrich of Flanders was renewed..."
p333: "...With the crowning of his son, Louis' actual exercise of authority came to an end; the condition of his health would have made this necessary in any case, and Philip II was in fact sole king. His first important step was his marriage in April, 1180, to the niece of the Count of Flanders, Isabel of Hainault, the childless count promising an important cession of the territory of southwestern Flanders to France to take place on his own death, and hoping no doubt to secure a permanent influence through the queen, while Philip probably intended by this act to proclaim his independence of his mother's family..."
