Origins & Early Life

The Kingdom of Gwynedd was a Welsh kingdom which first appeared at the turn of the sixth century. Based in northwest Wales, the rulers of Gwynedd repeatedly rose to dominance and were acclaimed as "King of the Britons" before losing their power in civil wars or invasions. The kingdom of Gruffudd ap Llywelyn—the King of Wales from 1055 to 1063—was shattered by a Saxon invasion in 1063 just prior to the Norman invasion of Wales, but the House of Aberffraw restored by Gruffudd ap Cynan slowly recovered and Llywelyn the Great of Gwynedd was able to proclaim the Principality of Wales at the Aberdyfi gathering of Welsh princes in 1216. In 1277, the Treaty of Aberconwy between Edward I of England and Llywelyn's grandson Llywelyn ap Gruffudd granted peace between the two but would also guarantee that Welsh self-rule would end upon Llywelyn's death, and so it represented the completion of the first stage of the conquest of Wales by Edward I. Welsh tradition credited the founding of Gwynedd to figures from Manaw Gododdin, perhaps the region around the mouth of the Firth of Forth, invading the lands of the Brittonic polities of the Deceangli, Ordovices, and Gangani in the 5th century. The sons of their leader, Cunedda, were said to have possessed the land between the rivers Dee and Teifi.

Pivotal Works & Achievements

The true borders of the realm varied over time, but Gwynedd proper was generally thought to comprise the cantrefs of Aberffraw, Cemais, and Cantref Rhosyr on Anglesey and Arllechwedd, Arfon, Dunoding, Dyffryn Clwyd, Llŷn, Rhos, Rhufoniog, and Tegeingl at the mountainous mainland region of Snowdonia opposite. The name Gwynedd is believed to be a borrowing from early Irish (reflective of Irish settlement in the area in antiquity), either cognate with the Old Irish ethnic name Féni, 'Irish people', from Primitive Irish*weidh-n- 'forest people' or 'wild people' (from Proto-Indo-European *weydʰ- 'wood, wilderness'), or alternatively Old Irish fían 'war band', from Proto-Celtic *weinā (from Proto-Indo-European *weyh₁- 'chase, pursue, suppress'). Ptolemy in the 1st century marked the Llŷn Peninsula as the "Promontory of the Gangani", which is also a name he recorded in Ireland. It is theorised in the 1st century BC some of the Gangani tribe may have landed in what is now the Llŷn Peninsula and had driven out the Deceangli or the Ordovices tribe from that area either peacefully or by force. In the late and post-Roman eras, Irish from Leinster may have arrived in Anglesey and elsewhere in northwest Wales with the name Llŷn derived from Laigin, an Old Irish form that means 'Leinstermen', or simply 'Leinster'.

Enduring Legacy & Impact

The 5th-century Cantiorix Inscription now in Penmachno church seems to be the earliest record of the name. It is in memory of a man named Cantiorix, and the Latin inscription is Cantiorix hic iacit / Venedotis cives fuit / consobrinos Magli magistrati: "Cantiorix lies here. He was a citizen of Gwynedd and a cousin of Maglos the magistrate". The use of terms such as "citizen" and "magistrate" may be cited as evidence that Romano-British culture and institutions continued in Gwynedd long after the legions had withdrawn. The background involving the Kingdom of Gwynedd starts with the history of Wales.
