'William II' (
1153 –
November 11 1189 Palermo), called 'the Good', was
king of Sicily and
Naples from 1166 to 1189.
Biography
William was only thirteen years old at the death of his father
William I, when he was placed under the regency of his mother,
Margaret of Navarre.

Until the king came of age in
1171 the government was controlled first by the chancellor
Stephen du Perche, cousin of Margaret (
1166–
1168), and then by
Walter Ophamil, archbishop of
Palermo, and
Matthew of Ajello, the vice-chancellor.
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 I Barbarossa. In
1174 and
1175 he made treaties with
Genoa and
Venice and his marriage in February
1177 with
Joan, daughter of
Henry II of England and
Eleanor of Aquitaine, marks his high position in European politics.
In July
1177, he sent a delegation of Archbishop
Romuald of Salerno and Count
Roger of Andria to sign the
Treaty of Venice with the emperor. To secure the peace, he sanctioned the marriage of his aunt
Constance, daughter of
Roger II, with Frederick's son Henry, afterwards the emperor
Henry VI, causing a general oath to be taken to her as his successor in case of his death without heirs. This step, fatal to the
Norman kingdom, was possibly taken that William might devote himself to foreign conquests.
Unable to revive the
African dominion, William directed his attack on
Egypt, from which
Saladin threatened the Latin
kingdom of Jerusalem. In July
1174, 50,000 men were landed before
Alexandria, but
Saladin's arrival forced the Sicilians to re-embark in disorder. A better prospect opened in the confusion in
Byzantine affairs which followed the death of
Manuel Comnenus (
1180), and William took up the old design and feud against
Constantinople.
Durazzo was captured (
June 11,
1185). Afterwards while the army marched upon
Thessalonica, the fleet sailed towards the same target capturing on their way the Ionian islands of
Corfu,
Cephalonia,
Ithaca and
Zakynthos. In August
Thessalonica fell to the joint attack of the Sicilian fleet and army and was subsequently sacked.

Peter of Eboli.
The troops then marched upon the capital, but the army of the emperor
Isaac Angelus defeated the invaders on the banks of the
Strymon (
September 7,
1185). Thessalonica was at once abandoned and in
1189 William made peace with Isaac, abandoning all the conquests. He was now planning to induce the crusading armies of the West to pass through his territories, and seemed about to play a leading part in the
Third Crusade. His admiral
Margarito, a naval genius equal to
George of Antioch, with 60 vessels kept the eastern
Mediterranean open for the
Franks, and forced the all-victorious Saladin to retire from before
Tripoli in the spring of
1188.
In November 1189 William died, leaving no children. Though
Orderic Vitalis records a (presumably short-lived) son in
1181:
Bohemond, Duke of Apulia. His title of "the Good" is due perhaps less to his character than to the cessation of internal troubles in his reign. The "Voyage" of
Ibn Jubair, a traveller in Sicily in 1183-1185, shows William surrounded by
Muslim women and
eunuchs, speaking and reading
Arabic and living like "a Moslem king."

Divine Comedy'',
Dante places William II in Paradise:
