Count of the district of Cerdagne in the eastern Pyrenees and claimant to the inheritance of Raymond of Saint-Gilles in Outremer.
A cousin of Raymond, William-Jordan accompanied him on the First Crusade (1096-1099) and remained with him in the East. After Raymond died while engaged in the siege of Tripoli (mod. Trâblous,Lebanon) in 1105, his younger son Alphonse-Jordan was sent back to succeed to the Saint-Gilles lands in the West. William-Jordan was accepted as successor to Raymond’s nascent county in the East, although he did not use the title “count of Tripoli.” His tenure was challenged by Raymond’s elder son, Bertrand, who arrived at Tortosa (mod. Tartûs, Syria) with a large force in 1109. William-Jordan abandoned the siege of Tripoli to Bertrand’s men and appealed to Tancred, regent of Antioch, agreeing to become his vassal in return for support. A settlement imposed by King Baldwin I of Jerusalem awarded Tortosa and Arqah to William-Jordan and the remaining domains to Bertrand. Shortly afterward William-Jordan was killed. Though the precise circumstances are unclear, the obvious beneficiary was Bertrand, who succeeded to Raymond’s undivided eastern inheritance.
