The native use of the title "Prince of Wales" appeared more frequent by the eleventh century as a modernised form of the old high kingship of the Britons. The Welsh had originally been the high Kings of the Britons; but the claim to be high king of late Romano-British Britain was no longer realistic after the death of Cadwaladr in 664.[2] Cadwaldr was also heavily associated with the symbol of the Red Dragon of Wales.[3][4] The princes of the medieval period hailed largely from west Wales, mainly Gwynedd.
