His son, John I, reigned eleven years, or from 1379 to 1390, though in 1385 the Duke of Lancaster, John of Gaunt, assumed the title of king, with the arms of Castile, Leon, and France. He was, however, dissuaded by the promise that his daughter Catherine (whose mother was Constance, daughter of Pedro the Cruel and Maria de Padilla) should marry Henry III, who succeeded to the throne of Castile in 1390, and reigned until 1406. The heir of this union was John II, who was King of Castile from 1406 to 1454, and whose chief claim to distinction is as the father of Isabella, who, after her brother, Henry IV, had died, in 1474, became Queen of Castile. Thus in the veins of the woman who was to become the greatest of her line ran the blood, not only of Pedro the Cruel, but of his bastard brother, Henry of Trastamare. But the resultant issue of her marriage with Ferdinand of Aragon, in 1469, was to be yet more deeply tinctured with the blood of the regicide; for the son of Henry of Trastamare had married a daughter of Pedro of Aragon, who was almost as cruel and implacable as Pedro of Castile. Ferdinand, son of John I, and grandson of Henry, became King of Aragon, and was succeeded by his son, John II of Aragon, through whom at his death the throne passed to Ferdinand, later called the Catholic, and who became the royal consort of Isabella. [Illustration] CHAPTER X. FERDINAND AND ISABELLA. What had hitherto been the curse of Spain, its intestinal divisions, feuds, rival projects of petty kings, was soon to be removed by the union of Isabella of Castile and Ferdinand of Aragon, whose marriage took place October 19, 1469. Isabella was eighteen years of age, Ferdinand only seventeen; but their training had been such that their intelligence and deportment were in advance of their years. They were cousins and lovers. Isabella was a blonde, with blue eyes and chestnut hair, a small but symmetrical figure, graceful and modest of carriage, intellectual, devout, charming, but not handsome. Ferdinand was tall and manly, a fine horseman, courteous, chivalrous, like his wife of the fair, Gothic type, eloquent of speech, with elegant bearing and polished manners. These were the two who for thirty years were to reign together, who were to unite the dismembered fragments of war–harried Spain, who were to establish a throne that was to command the respect of all Europe, a kingdom whose influence was to extend around the world. And yet, if the historians are to be credited, they were so poor at the time of their betrothal that they were compelled to borrow money for their wedding. Fortunately, their credit was good, for, despite their poverty, it was known to all that they had great expectations. But their enemies pressed them hard, and it was only by stealing off in disguise, with a few attendants merely as company, that Ferdinand was able to reach Valladolid, where Isabella was awaiting him, and claim his bride.
