Why did John anger william des Roches?
Perhaps: (according to historians)
- the aftermaths of Mirebeau revealed self-destructive tendencies
- warren: John suffering from over-confidence born of success and his inveterate distrust of powerful subjects
- William was increasingly a threat to John, summer 1201 he married Marguerite de Sable acquiring a vast landholding becoming one of the greatest barons of Anjou and Maine. To have granted William control of Arthur, it would have provided him a means to destroy Angevin dominions.
- As long as John had Arthur = a powerful means to coerce the Bretons into loyalty
