William II of Hauteville, called the Good, king of Sicily

In 1166, under the guardianship of Margaret of Navarre, he succeeded William I to the throne of Sicily. In contrast to his father, he was called ‘the Good’. He married Joanna, the daughter of the Plantagenet king of England, Henry II. In 1184 he consented to the marriage of the legitimate heir of the Norman dynasty, the thirty-year-old Constance, to Emperor Frederick I’s eldest son, Henry. The last male descendent of the Hautevilles on the Sicilian throne, William died heirless in 1189.
