Merfyn Frych - Political Background

Political Background

The times leading up to Merfyn's reign were unsettled for both Gwynedd and neighbouring Powys. Both kingdoms were beset by internal dynastic strife, external pressure from Mercia, and bad luck from nature's whims. In 810 there was a bovine plague that killed many cattle throughout Wales. The next year Deganwy, the ancient fortified llys (English: royal court) of Maelgwn Gwynedd and built of wood, was struck by lightning. A destructive dynastic war raged in Gwynedd between 812 and 816, particularly on Anglesey, while in Powys a son of the king was killed by his brother "through treachery". In 818 there was a notable battle at Llanfaes on Anglesey. The combatants are not identified, but the site had been the llys of King Cynan.

Coenwulf of Mercia took advantage of the situation in 817, occupying Rhufoniog (see map) and laying waste to the mountains of Eryri (English: Snowdonia), the defensive stronghold of Gwynedd. Coastal Wales along the Dee Estuary was still in Mercian hands in 821, as it is known that Coenwulf died peacefully at Basingwerk in that year. In 823 Mercia laid waste to Powys and returned to Gwynedd to burn down Deganwy.

Gwynedd and Powys then gained a respite when Mercia's attention turned elsewhere and its fortunes waned. King Beornwulf was killed fighting the East Anglians in 826, his successor Ludeca suffered the same fate the following year, and Mercia was conquered and occupied by Ecgberht of Wessex in 829. Though Mercia managed to throw off Ecgberht's rule in 830, it was thereafter beset by dynastic strife, and never regained its dominance, either in Wales or eastern England.

It was just as Mercian power was on the verge of breaking that Merfyn Frych came to the throne, certainly a case of fortuitous timing.
