So Jayme the youth was named, Jayme being the popularly accepted Aragonese form for James, and early in life he entered upon an active career which soon showed him to possess a strong and crafty nature, though he was at the same time brutal, rough, and dissolute. In his various schemes for conquest and national expansion, he stopped at nothing which might ensure the success of his undertakings, and in particular did he attempt by matrimonial ventures of various kinds to increase his already large domain. This rather unusual disregard of the sacredness of the marriage relation, even for that time, may have been induced to some extent by the atmosphere in which he passed his youthful days; for his mother, the devout Queen Maria, in spite of all her pious zeal for the Church, was pleasure-loving, and in the excitement of court life it was whispered that she had looked with favor more than once upon some gallant troubadour from Provence who had written verses in her honor. Jayme's first marriage was with Eleanor of Castile, Berenguela's sister, but when he discovered that the young Castilian king, Fernando, was strong and capable and that there was no possibility whatever of an ultimate union of Aragon and Castile, at least within his own time, he promptly divorced Eleanor, and then wedded Yolande, the daughter of King Andrew of Hungary. Yolande's eldest son, Pedro, was married to Constance, daughter of King Manfred of Sicily, for purely political reasons; and when the King of France opposed this alliance as one detrimental to the best interests of the pope, who was being much aided at this time by Gallican support, Jayme cleverly silenced this complaint by marrying his daughter Isabel to Philip, the French dauphin. This daring King of Aragon had dreams of a great Romance Empire which might extend all over the southern part of Europe, with Aragon as its centre, and it was to this end that he bent all his energies. While he was not able to realize this fond hope, he was remarkably successful; and not a little of his success must be attributed to his lack of sentiment and his practical view of the matrimonial question.
