Though his policy to the last remained one of peace, yet the acquisition of Britanny forced him to guard against attack from France and the mastery of the Channel which the possession of the Breton ports was likely to give to the French fleet.

The same dread of French attack drew Ferdinand of Aragon and Isabel of Castile, whose marriage was building up the new monarchy of Spain, to the side of the English king; and only a few years after his accession they offered the hand of their daughter Catharine for his eldest son.

But the invasion of Italy by Charles the Eighth drew French ambition to a distant strife, and once delivered from the pressure of immediate danger Henry held warily back from a close connexion with the Spanish realms which might have involved him in continental wars.

It was not till 1501 that the marriage-treaty was really carried out.

The Low Countries had now passed to the son of Mary of Burgundy by her husband Maximilian, the Austrian Archduke Philip.
