The Greatest Welsh Ruler: Episode 1 (350 to 1063)

September 7, 2025·56 min·5 clips

Cadwallon, the last Welsh king to rule parts of England, was called a bloody tyrant by the historian Bede.

Wales is still here. That plain little line carries the episode, as the host and Stephen start sorting through possible candidates for the greatest rulers of Wales. First comes Maxen Gweledig, or Magnus Maximus, the figure tied to the departing legions and the handoff of power to Coelhean, Hynedd, and other founding rulers. The mood stays light, but the question underneath is serious enough: what happens to Welsh power after Rome pulls back? Then Hynedd arrives. Stephen presents him as the founding father of the dynasty that would rule Gwynedd, probably around 450 AD, though nobody pretends the ground is firm. The episode keeps returning to possible, probably, and who knows, because early Welsh origin stories are built from legend, memory, and partial sources. Hynedd may have had Roman links. He may have been installed by Maxen. He may have acted for Vortigern. The Irish piece matters too. The conversation connects Irish landing and settlement with the heavy Roman garrisoning of Wales, then uses the Llyn Peninsular and a local place-name to show how closely the two sides of the Irish Sea were tied together. Nennius comes in as a useful clue rather than a settled answer. His story of Hynedd going to Gwynedd to drive out the Irish sits inside a bigger argument about descent, legitimacy, and the stories dynasties told about themselves. Gwynedd looks back to Hynedd. Powys looks toward Vortigern. The result is a lively Welsh argument over memory, power, and origins.
