Alfonso Jordan Alfonso Jordan ( ; ) ( 1103 – 1148 ) was the Count of Tripoli ( 1105 – 09 ) , Count of Rouergue ( 1109 – 48 ) and Count of Toulouse , Margrave of Provence and Duke of Narbonne ( 1112 – 48 , as Alfonso I ) . He was the son of Raymond IV of Toulouse by his third wife , Elvira of Castile . He was born in the castle of Mont Pèlerin in Tripoli while his father was on the First Crusade . He was given the name " Jordan " after being baptised in the Jordan River . Alfonso ' s father died when he was two years old and he remained under the guardianship of his cousin , William Jordan , Count of Cerdagne , until he was five . He was then taken to Europe , where his half - brother Bertrand had given him the county of Rouergue . Upon Bertrand ' s death in 1112 , Alfonso succeeded to the county of Toulouse and marquisate of Provence . In 1114 , Duke William IX of Aquitaine , who claimed Toulouse by right of his wife Philippa , daughter of Count William IV , invaded the county and conquered it . Alfonso recovered a part in 1119 , but he was not in full control until 1123 . When at last successful , he was excommunicated by Pope Callixtus II for having expelled the monks of Saint - Gilles , who had aided his enemies . Alfonso next had to fight for his rights in Provence against Count Raymond Berengar III of Barcelona . Not until September 1125 did their war end in " peace and concord " ( " pax et concordia " ) . At this stage , Alfonso was master of the regions lying between the Pyrenees and the Alps , the Auvergne and the sea . His ascendancy was , according to one commentator , an unmixed good to the country , for during a period of fourteen years art and industry flourished . In March 1126 , Alfonso was at the court of Alfonso VII of León when he acceded to the throne . According to the " Chronica Adefonsi imperatoris " , Alfonso and Suero Vermúdez took the city of León from opposition magnates and handed it over to Alfonso VII . Among those who may have accompanied Alfonso on one of his many extended stays in Spain was the troubadour Marcabru . About 1134 Alfonso seized the viscounty of Narbonne and ruled it during the minority of the Viscountess Ermengarde , only restoring it to her in 1143 . In 1141 King Louis VII pressed the claim of Philippa on behalf of his wife , Eleanor of Aquitaine , even besieging Toulouse , but without result . That same year Alfonso Jordan was again in Spain , making a pilgrimage to Saint James of Compostela , when he proposed a peace between the king of León and García VI of Navarre , which became the basis for subsequent negotiations . In 1144 , Alfonso again incurred the displeasure of the church by siding with the citizens of Montpellier against their lord . In 1145 , Bernard of Clairvaux addressed a letter to him full of concern about a heretic named Henry in the diocese of Toulouse . Bernard even went there to preach against the heresy , an early expression of Catharism . A second time he was excommunicated ; but in 1146 he took the cross ( i . e . , vowed to go on crusade ) at a meeting in Vézelay called by Louis VII . In August 1147 , he embarked for the near east on the Second Crusade . He lingered on the way in Italy and probably in Constantinople , where he may have met the Emperor Manuel I . Alfonso finally arrived at Acre in 1148 . Among his companions he had made enemies and he was destined to take no share in the crusade he had joined . He died at Caesarea , and there were accusations of poisoning , usually levelled against either by Eleanor of Aquitaine , the wife of Louis , or Melisende , the mother of King Baldwin III of Jerusalem . By his wife since 1125 , Faydiva d ' Uzès , he left two legitimate sons : Raymond , who succeeded him , and Alfonso . His daughter Faydiva ( died 1154 ) married Count Humbert III of Savoy . He left two other daughters : the legitimate Agnes ( died 1187 ) and the illegitimate Laurentia , who married Count Bernard III of Comminges .
