Alfonso Jordan, also spelled Alfons Jordan or Alphonse Jourdain (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). Life Alfonso 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 "Jourdain" 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 damaged the abbey of Saint-Gilles and assaulting the monks. 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. By 1132, Alfonso was embroiled in a succession war over the county of Melgueil against Berenguer Ramon, Count of Provence. This brief conflict was resolved with Alfonso's defeat and Berenguer marrying Beatrice, heiress of Melgueil. Alfonso seized the viscounty of Narbonne in 1134, and ruled it during the minority of the Viscountess Ermengarde, only
