The Princes of Snowdonia
By the Middle Ages, the main kingdoms of Wales were Gwynedd, Powys and Deheubarth. On the whole, Gwynedd was the most powerful kingdom in Wales, mainly due to the fact that Snowdonia’s mountainous terrain was an aid to defend the area. Gwynedd’s supremacy can be traced back to Maelgwn Gwynedd’s reign during the C6. In his day, Maelgwn was Wales’ most powerful leader.
In 825, a new dynasty was established in Gwynedd, by Merfyn Frych. His successor was Rhodri Mawr, one of Gruffudd ap Cynan’s ancestors. Gruffudd ap Cynan re-established Rhodri Mawr’s dynasty in 1098. Llywelyn ab Iorwerth and Llywelyn ap Gruffudd, two of Gwynedd’s most celebrated leaders, were both members of this dynasty.
The Welsh Principality was formally established in 1267, as part of the Treaty of Monmouth, when Edward I acknowledged Llywelyn ap Gruffudd as Prince of Wales. Llywelyn ap Gruffudd was killed in Cilmeri in 1282 and his only heir, Princess Gwenllïan, was sent to live in a convent in Sempringham, Lincolnshire. Dafydd ap Gruffudd, Llywelyn ap Gruffudd’s brother, inherited the title of Prince of Wales, but the dynasty soon came to an end, when Dafydd was executed in 1283. This marked the completion of the Edwardian Conquest of Wales.
The Welsh Principality established by the Princes of Gwynedd did survive, however, as the area wasn’t included as part of the English kingdom. When Edward I’s son, Edward of Caernarfon, became Prince of Wales in 1301, he received the Welsh Principality, as it had been designated in 1267. Until the Act of Union between England and Wales in 1536, Wales was split in two parts: the Principality and the Marches. ‘The Principality’ is now considered to be the whole of Wales, as it is geographically designated today.
