Bohemond, Duke of Apulia

William II, called the Good, was king of Sicily from 1166 to 1189. Our understanding of William's character is very indistinct. Lacking in military enterprise, secluded and pleasure-loving, he seldom emerged from his palace life at Palermo. Yet his reign is marked by an ambitious foreign policy and a vigorous diplomacy. Champion of the papacy and in secret league with the Lombard cities he was able to defy the common enemy, Frederick Barbarossa. In the Divine Comedy, Dante places William II in Paradise. He is also referred to in Boccaccio's Decameron.
