In 1475, James III of Scotland forfeited the MacDonald Earldom of Ross and although the MacDonald Lordship of the Isles was not forfeited until 1493, in many ways 1475 marked the end of the lordship as a potent force. Following this is what the Books of Clanranald describe as a "great struggle for power among the Gael". Various leaders, such as Aonghas Óg who was the fourth illegitimate son of the Lord of the Isles, along with his son, Domhnall Dubh, and also Alexander MacDonald of Lochalsh and John Mor MacDonald of Dunyvaig were seeking to restore the MacDonald hegemony in the west. The Battle of Bloody Bay took place in 1480 where John MacDonald of Islay, Lord of the Isles and chief of Clan Donald was defeated by his son Aonghas Óg. Aonghas Óg's son Domhnall Dubh rebelled against James IV of Scotland and made an alliance with Edward VI of England in an attempt to regain the Lordship of the Isles and although various attempts were made to restore the lordship, by 1545 all had failed. The ultimate victors were the Crown's hard men in the north and west: Alexander Gordon, 3rd Earl of Huntly (chief of Clan Gordon), Archibald Campbell, 2nd Earl of Argyll (chief of Clan Campbell) and John MacIain of Ardnamurchan. The various branches of the Clan Donald began accepting charters from the Crown in recognition of their separate holdings. This was part of a royal policy that successfully kept the Clan Donald divided, and in doing so they were less of a threat to the central authority.
