Richard, first earl of Cornwall and king of Germany (1209–1272), was born at Winchester on 5 January 1209, the second son of King John (1167–1216) and his queen, Isabella of Angoulême (c.1188–1246). Brother of Henry III. At this time Richard was just about to become chief counsel to Queen Eleanor, who was to act as regent while Henry III was in Gascony, although, in fact Richard was to have the regnal power. The licence seems to be a royal 'blessing' and token, given at Portsmouth, as the king was about to depart. Richard was one of the few people granted a licence who would have had the money to build and garrison a military stronghold but Mere was a relatively modest castle.
