In 1489 Henry VII was attempting to prop up Brittany against French encroachment and also pursuing a marriage between his heir Arthur and the infant Catherine, daughter of Ferdinand of Aragon and Spain. In March 1489 the treaty of Medina del Campo confirmed the marriage arrangements and concluded an alliance against France. But in 1491 the duchess of Brittany married Charles VIII of France and the realms were united. The marriage of Catherine and Arthur was postponed until 1501 and within five months Arthur had died.
