Post-Roman Celtic Kingdoms

Gwynedd

Located in northwest Wales in the former British territories of the Deceangli and Ordovices. A group of Votadini Picts (nominal Britons from the Pictish border areas) under Cunedda Wledig were transferred by Magnus Maximus to secure Western Britain from Irish raiders, moving from the Manau Goutodin kingdom. In Wales, Cunedda governed most of the north (hence "King of North Wales"). His father and grandfather bore Roman names and in true Celtic fashion, Cunedda could trace his lineage back to Beli Mawr.

Following that Celtic tradition, upon Cunedda's death the territory under his control was divided between his sons. Most of these were "regained" by the main Gywneddian kingdom within a generation or two. Ceredigion, along the upper west coast of Wales, remained independent for much longer. The name of  Gwynedd either derives from the Latin Venedotia, or more probably from Cunedda (=Weneda =Gwynedd).

1282

With the death of Llywelyn ap Gruffydd in 1282 and his brother Dafydd the following year, 400 years of dominance by the house of Gwynedd comes to an end. Gwynedd had survived intense rivalries from within Wales, as well as outside threats from Irish, Angles, Saxons, Vikings and Norman raiders and would-be-conquerors. It had done so through a combination of might and well-placed diplomacy that nevertheless failed to withstand the final, determined assault from the English in the person of Edward I. Llywelyn is beheaded and the grisly trophy taken by Roger Mortimer of Chirk to Rhuddlan. This he presents to a thankful King Edward who dispatches it at once to be displayed on the Tower of London to the great mirth of the townsfolk.
