-------------------------

William III (c. 970 – 1042) was the Margrave of Montferrat and Count of Vado from 991 to his death. He was the eldest son and successor of Otto I. William I and II were the father and son respectively of Aleram, the first margrave, but neither served as margrave himself.

William's religious policy was a continuation of Aleram's. He founded the monastery of Spigno. In 1014, he and his brother Riprando donated land to the abbey of Fruttuaria. Between his succession and 1002, he made other donations to Acqui Terme.

While following in the familiar policy of ecclesiastical patronage, William abandoned Aleram's support of the Holy Roman Emperors. Instead, he intervened in the wars of the Italian communes which characterised early eleventh-century Italy. He joined an anti-imperial alliance with Count Obert the Red, Margrave Ulric Manfred II of Turin, and Bishop Leo of Vercelli. The allies soon found themselves at odds and warring on each other. Leo besieged Santhià, where William was then residing, and William, to avenge himself on the bishop, besieged Vercelli and put it to flame. William signed a peace treaty with Ulric Manfred and married his son Henry to Manfred's daughter Adelaide.

Even after all his allies had been pacified by imperial troops, William continued to resist Conrad II, but he fared poorly. Conrad destroyed his fortress in the valley of Orba.

The Miracula sancti Bononii records William's wife as Waza. She prayed at the tomb of Saint Bononio, abbot of Santissimi Michele e Genuario di Lucedio. William died in 1041, probably before 29 January, when his son Henry cites him in an act donating land to the church in Turin.

46 A HISTORY OF THE CRUSADES II
William III, marquis of Montferrat; Roger de Mowbray, lord of Thirsk in Yorkshire; and many another baron, knight, and sergeant were captured. Large numbers of Christians were slain in the battle, and Saladin slaughtered all the rank and file of the Temple and Hospital who fell into his hands. The True Cross, borne in the midst of the host by a succession of prelates, came into the possession of the "infidels". In mustering his army to meet Saladin's invasion king Guy had drained his fortresses of their garrisons. Except for Raymond III, count of Tripoli, Reginald, lord of Sidon, and Balian of Ibelin, who had escaped from the field of Hattin, the realm of Jerusalem was leaderless.1 Acre fell almost at once, and Saladin soon conquered most of the other towns and castles. By the end of 1187 the only important towns still holding out were Tyre, Tripoli, and Antioch.

Tyre was saved by a stroke of chance - the fortuitous arrival of an able, vigorous soldier of high rank. Conrad of Montferrat, eldest surviving son of marquis William, and uncle of the young king Baldwin V of Jerusalem, had started for the Holy Land in 1185. Conrad had stopped in Constantinople and entered the service of Emperor Isaac II Angelus. When he learned of the threatened invasion of the kingdom of Jerusalem, he obtained the emperor's leave to go to Palestine. The ship bearing him and his small band arrived at Acre after its capture by Saladin. Fortunately for the Franks Conrad discovered the state of affairs before he landed, and promptly sailed up the coast to Tyre. He found that city about to surrender. The commander of the town, lacking both garrison and supplies, had agreed with Saladin on terms of capitulation. But the citizens took heart from Conrad's arrival, delivered the city to him, and prepared to defend it under his leadership.2 Tyre became the refuge for the inhabitants of the places captured by Saladin during the following months, for the sultan's conquest of the kingdom of Jerusalem was no orgy of bloodshed. Although Saladin was fully capable of savage cruelty, he preferred to be merciful - especially when mercy paid. The towns of the kingdom were leaderless and had almost no soldiers, but they were strongly fortified. The inhabitants were discouraged by the loss of the leaders and troops, and were willing to surrender in exchange for their lives. Saladin's troops were horsemen who felt at home only in the open field and had no taste for attacking fortifications. Hence it was good policy
