Bohemond III., grandson of Raymond of Poictiers, and descended, in the female line, from the celebrated Bohemond, one of the heroes of the first crusade, governed the principality of Antioch and the county of Tripoli. Amidst the misfortunes that afflicted the Christian colonies, the sole aim of this prince was the extension of his dominions, and every means appeared to him good and just that could forward his designs. Bohemond pretended to have claims to the principality of Armenia; and employed by turns force and stratagem to get possession of it. After several useless attempts, he succeeded in decoying into his capital Rupin of the Mountain, one of the princes of Armenia, and detained him prisoner. Livon, the brother of Rupin, determined to take signal vengeance for such an outrage; and, under the pretence of treating for peace, invited Bohemond to repair to the frontiers of Armenia. The two princes engaged by oath to come without escort or train to the place of conference; but each formed a secret design of laying a snare for his adversary. The Armenian prince, better seconded by either his genius or fortune, remained conqueror in this disgraceful contest. Bohemond was surprised, loaded with chains, and carried away to a fortress of Lesser Armenia. The war was instantly renewed with fury; the people of both Armenia and Antioch rushed to arms, and the countries and cities of the two principalities were speedily by turns invaded and ravaged. At length peace became desirable, and after some disputes upon the conditions, the prince of Antioch was sent back to his states, and Rupin of the Mountain was restored to the nations of Armenia. By an agreement entered into by the two princes, Alice, the daughter of Rupin, married the eldest son of Bohemond. This union promised to be the pledge of a durable peace; but the germ of so many divisions still subsisted; the two parties retained a strong feeling of the outrage they had received; and every treaty of peace becoming a fresh subject of discussion, war was always ready to be rekindled.
