Edward II of England formally ended Edward's reign. A proclamation was sent to London, announcing that Edward, now known just as Edward of Caernarvon, had freely resigned his kingdom and that Prince Edward would succeed him. The coronation took place at Westminster Abbey on 2 February 1327. Those opposed to the new government began to make plans to free Edward, and Roger Mortimer decided to move Edward to the more secure location of Berkeley Castle in Gloucestershire, where the former King arrived around 5 April 1327. Once at the castle, Edward was kept in the custody of Mortimer's son-in-law, Thomas Berkeley, and John Maltravers,
Baron Berkeley that the barony by writ was deemed, extraordinarily, to be in effect a feudal barony (or barony by tenure), dependent on the tenure of Berkeley Castle. Thus when William Berkeley, 1st Marquess of Berkeley, 2nd Baron Berkeley (1426–1492), "William the Waste-All", alienated Berkeley Castle to the king, he effectively disinherited his younger brother from the barony by writ.

In 1942 both titles became extinct
