On the 7th May 1502, Joan and her husband entered the imperial city of Toledo with all the ceremony that Castile could supply. At the door of the great hall in the Alcazar, Isabel stood to receive her heirs. Both knelt before her and tried to kiss her hand, but the Queen raised them, and embracing her daughter, carried her off to her private chamber. Soon afterwards the Archduchess and her husband took the oath as heirs of Castile in the vast Gothic Cathedral; and the splendid festivities to celebrate the event were hardly begun before another trouble came in the announcement of the death of Arthur, Prince of Wales, husband of Isabel’s youngest daughter, Katharine. The event immediately changed the aspect of the game. The next heir of England was a boy of eleven, who might be married to a French princess, and thus cause one other blow to Ferdinand’s carefully arranged schemes. This made it more necessary than ever that Joan and Philip should be brought into entire obedience to Spanish views. War broke out between France and Spain at once, and strenuous efforts were made by Ferdinand to expel from Spain the councillors of Philip, who were known to be in the French interest.[91] The Archduchess and her husband were then taken to Aragon, to receive the homage of the Cortes there as heirs of Ferdinand, and then Philip, in spite of all remonstrance, hurried back again to his own country. Isabel gravely took her son-in-law to task when he announced his intention to return to Flanders by land through France whilst Spain was at war. It was, she said, his duty to recollect, moreover, that he was, in right of his wife, heir to one of the greatest thrones in the world, and should stay at least long enough in the country to know the people and their language and customs. To her entreaties the Archduchess, now far advanced in pregnancy, and unable to travel, added her prayers and tears. But all in vain; Philip, against the respectful protest even of the Cortes, would go, and insisted upon travelling through France, the enemy of Spain.[92] So, almost in flight, Philip of Burgundy crossed the frontiers of his father-in-law, leaving his wife Joan and their unborn child in Castile, in December 1502.
