The king of Jerusalem, as protector of the confederation of the Franks in Asia, determined to re-establish order, and took the road to Antioch with his barons and the knights of the Temple and St. John. The count of Tripoli, who had embraced the party of Alise, undertook to stop the king of Jerusalem on his passage. The powers of these two princes met; a battle ensued, and the plains of Phœnicia were stained with the blood of Christians shed in unnatural strife. Foulque of Anjou, after having routed the troops of the count of Tripoli, gained the banks of the Orontes, silenced the contending factions, and re-established peace. To perfect his work, he resolved to bestow the daughter of Bohemond on a husband able to defend her rights, who would merit the confidence of the Christian warriors. Syria presenting to him no prince or knight worthy of his choice, he turned his eyes towards the princes of Europe, and nominated Raymond of Poictiers governor of Antioch, as Baldwin II. had chosen him himself governor of Jerusalem. Thus Europe, which had found defenders for the Christian states of Asia, supplied them also with princes and kings. Raymond of Poictiers, brother of William, duke of Aquitaine, left France with the scrip and staff of a pilgrim, and came into Syria to espouse the daughter of Baldwin, and reign with her on the banks of the Orontes. The troubles of Antioch had revived the pretensions of the emperors of Constantinople. John Comnenus, son and successor of Alexius, put himself at the head of an army, took possession of some places in Cilicia, and encamped before the walls of Antioch. After several conflicts, in which victory remained uncertain, negotiations were opened, which ended in the oath of obedience to the emperor being taken by Raymond of Poictiers. The two princes, united by a treaty, resolved to turn their arms against the Saracens. Their troops, which they commanded in person, attacked without success Aleppo and several other cities of Syria; the want of a good understanding, which accompanied the Greeks and Latins at all times, was sure to defeat their enterprises. The emperor returned with vexation to Antioch, of which he endeavoured to make himself master, but was compelled by a sedition to leave the city hastily. He then formed the project of visiting Jerusalem at the head of his army, with the intention, if the Latins are to be believed, of obtaining possession of Palestine. Foulque sent ambassadors to inform him that he could only be received in the holy city in the character of a simple pilgrim; whereupon John, who did not dare to complain, sent presents to Foulque of Anjou, and gave up, without much pain, his idea of a pilgrimage to Jerusalem. After a campaign, for which he had drawn out all the strength of the empire, he returned to his capital, having obtained nothing by his enterprise but the vain and hollow homage of the prince of Antioch.
