List of rulers of Wales

Prior to the King or Prince of Wales title, the title King of the Britons was used to describe the King of the Celtic Britons, ancestors of the Welsh.[4] The Brut y Tywysogion, Gwentian Chronicles of Caradoc of Llancarvan version, which was written no earlier than the mid 16th century lists multiple Kings of the Britons as a "King of Wales".[5][6][7]

The following is a list of those assigned or claiming the title of King or Prince of Wales, including "Sovereigns and Princes of Wales 844 – 1283".[2] While many different leaders in Wales claimed the title of 'King of Wales' and ruled majorities of Wales, the modern-day territory of Wales was only fully united under the direct rule of Gruffydd ap Llywelyn from 1055 to 1063 according to historian John Davies.[8][2] Gruffydd ap Llywelyn was referred to as King of Wales or Rex Walensium by John of Worcester.[9] He was the last of a long line of paramount rulers among the insular Britons to have the title of King of the Britons bestowed upon him, and possibly the only one to truly rule over all the (independent) Britons. By this time, if not earlier, Wales was the only part of Britain remaining under Brittonic rule.[10]

The native use of the title 'Prince of Wales' appeared more frequent by the eleventh century as a 'modernised' or reformed form of the old high kingship of the Britons. The Welsh had originally been the high Kings of the Britons up until the claim to be high king of late Romano-British Britain was no longer realistic after the death of Cadwaladr in 664.[19] Cadwaldr was also heavily associated with the symbol of the Red Dragon of Wales.[20][21] The princes of the medieval period hailed largely from west Wales, mainly Gwynedd. They had such significant authority that allowed them to claim authority beyond the borders of their kingdoms. This allowed many Princes to claim to rule all Wales.[1]

Llywelyn the Last, the last Prince of Wales was ambushed and killed in 1282. The execution of his brother Dafydd ap Gruffydd in 1283 on the orders of King Edward I of England effectively ended Welsh independence. The title of Prince of Wales was then used by the English monarchy for the heir to the English throne.[22][23]

During the period 1400–1413, following a rebellion against English rule in Wales, there existed a native Prince of Wales, Owain Glyndwr and an English monarchy appointed Prince of Wales (who later became Henry V of England). The native Prince of Wales, Owain Glyndwr led Welsh forces against the English Prince of Wales and English rule in Wales.[24][25]
