Conrad
Conrad, Marquis of Tyre, son of William, Marquis of Montferrat, entered the service of the Pope Alexander III., and fought against Frederick I. In 1186 he went to Syria and took part in the Third Crusade. On his way he assisted Isaac Angelus in the defence of Constantinople, and received as reward the hand of Theodora. Narrowly escaping capture at Acre, he threw himself into Tyre, then besieged by Saladin, and held the city till relieved by Richard Coeur de Lion and Philip Augustus. Proclaimed sovereign of Tyre, he aspired to follow Guy de Lusignan as king of Jerusalem, and would probably have done so had he not been assassinated in 1190 by emissaries of the Old Man of the Mountains.
