Henry was count of Anjou, duke of Normandy, and overlord of about half the other
counties of northern France. He was also duke of Aquitaine by his marriage to
Eleanor, heiress of that vast southern French duchy. As for his power in the British
Isles: the princes of Wales swore him homage and fealty; the rulers of Ireland were
forced to submit to him; and the king of Scotland was his vassal. Thus Henry
exercised sometimes more, sometimes less power over a realm stretching from
northern England to the Pyrenees. (See Map 6.4 on p. 206.) For his Continental
possessions, he was vassal of the king of France.
