Catharine however was widow almost as soon as wife, for only three months after his wedding Arthur sickened and died. But a contest with France for Southern Italy, which Ferdinand claimed as king of Aragon, now made the friendship of England more precious than ever to the Spanish sovereigns; and Isabel pressed for her daughter's union with the king's second son, Henry, whom his brother's death left heir to the throne. In his anxiety to avoid a breach with Spain the king suffered Henry to be betrothed to Catharine, and threw the burthen of decision on Rome. A dispensation was necessary, and the case was of course the more difficult if the first marriage had been completed. The pleadings were put in, though both Julius the Second and Henry were in no haste for a decision. But the victories of Spain in Southern Italy enabled Isabel to put fresh pressure on the Pope, and on a denial being given of the consummation of the earlier marriage Julius was brought to sign a bull legitimating, even in case of such a consummation, the later one. Henry however still shrank from any real union. His aim was neither to complete the marriage, which would have alienated France, nor to wholly break it off and so alienate Spain. A balanced position between the two battling powers allowed him to remain at peace, to maintain an independent policy, and to pursue his system of home-government. He guarded his son's interests therefore by suggesting that he should enter a secret protest against the validity of his betrothal; and Catharine remained through the later years of his reign at the English court betrothed but unmarried, sick with love-longing and baffled pride.
