Matters, however, did not go quite smoothly; nor was John without a rival. Some months after his elder brother, Geoffrey, was killed in the tournament at Paris, Geoffrey’s widow, Constance of Brittany, gave birth to a son, to whom the Bretons, in honour of the memory of their mythical hero, gave the name of Arthur. King Richard was well inclined towards his nephew, and anxious to educate the boy to succeed him. But Constance, a weak and somewhat vicious woman, refused to place her son in the custody of Cœur de Lion, who, in consequence, recognised John as his heir. Nevertheless, on Richard’s death, the people of Anjou and Brittany proclaimed young Arthur as their sovereign; and Constance, carrying him to the court of Paris, placed him under the protection of Philip Augustus. But Philip, after making great professions, and promising to give Arthur one of his daughters in marriage, concluded a treaty with John in 1200, and, without scruple, sacrificed all the boy’s interests. And now John’s throne seemed secure; and both the crown of England and the coronal of golden roses--the diadem of Normandy--sat easily on his brow; but at this juncture his indiscretion hurried him into a matrimonial project which cost him dear. It was the summer of 1200, and John made a progress through Guienne to receive the homage of that province. In Angoulême, at a great festival given in his honour, his eye was attracted and his imagination captivated by Isabel, daughter of the count of that beautiful district--a lovely nymph not more than sixteen. John became passionately enamoured; and as “maidens, like moths, are caught by glare,” Isabel to be “a crowned queen” was “nothing coy.” It is true that there were serious obstacles in the way of a matrimonial union. John had previously been married to a daughter of the Earl of Gloucester, and Isabel affianced to Count Hugh de la Marche. But the obstacles were not deemed insuperable; for the Church had forbidden John to take home his bride, on account of their nearness of kin; and he, as sovereign of Angoulême, had power to break the link which bound the fair heiress to the man to whom she had been betrothed. Moreover, the parents of the young lady encouraged John’s passion; and, all difficulties having been got over for the time being, John and Isabel were united at Bordeaux, and sailed for England. On their arrival a grand council was held at Westminster; and Isabel of Angoulême, having been acknowledged as queen, was formally crowned by the Archbishop of Canterbury.
