The accession of Lewis XII. in 1497 affected French policy. Lewis required in the first place, to gain the friendship of the Pope Alexander VI., in order to obtain a divorce from his wife and a dispensation to marry Charles's widow, Anne of Brittany, so as to retain the duchy. In the second place, he claimed Milan as his own in right of his descent from Valentina Visconti (not as an appanage of the French Crown). He was anxious then to conciliate both Spain and England, and ready to make concessions to both in order to hold them neutral. His first steps, therefore, aimed at satisfying them, and at detaching the Archduke Philip from his father Maximilian; all of which objects were rapidly accomplished, England obtaining the renewal of the treaty of Etaples, with additional undertakings in the matter of harbouring rebels. Lewis made separate treaties with Spain and with Philip; but the former remained none the less anxious on the score of a possible further _rapprochement_ between France and England. [Sidenote: The Spanish marriage negotiation, 1499-1501] So long as Perkin Warbeck had been able to pose as Richard of York, he was necessarily, to all who believed in him, the legitimate King of England. Setting him aside, it was still possible to argue for the Earl of Warwick as against his cousin Elizabeth, Henry's queen. But when Perkin and Warwick were both put to death at the end of 1499, there was no arguable case for any one outside Henry's own domestic circle. Even if it were held that Henry's title was invalid, and that a woman could not herself reign in her own right, Elizabeth's son had indisputably a title prior to any other possible claimant. It was stated, though the truth of the statement is doubtful, that the Spanish sovereigns had never felt at ease as to the stability of the Tudor dynasty till November, 1499; but, at any rate, after that date they could not even for diplomatic purposes pretend to feel any serious apprehensions. The year 1500 presents the somewhat curious spectacle of Henry on one side and Ferdinand and Isabella on the other, each quite determined to carry through the marriage of Arthur and Katharine, but each also determined to make a favour of it. In this diplomatic contest, Henry proved the more skilful bargainer, though the Spaniards were adepts. He frightened them not a little by crossing the Channel and holding a conference with the Archduke Philip, which was suspected of having for its object the negotiation of another marriage for the Prince of Wales with Philip's sister (Maximilian's daughter) Margaret, who was already a widow. [Footnote: Margaret had been married to Don John, son of Ferdinand and Isabella; while Philip married their second daughter Joanna. Their eldest daughter married the Portuguese Infant.] In fact, there was no such intention; but an agreement was actually made that Prince Henry should many Philip's daughter, while the youngest Tudor princess,
