Located on the eastern border of Powys, Pengwern stretched deep into the Midlands. It was originally part of Powys, and apparently remained so until the last quarter of the sixth century. During at least some of that time its capital was probably Caer Guricon (the former tribal capital of the Cornovii tribe, Roman Viroconium, modern Wroxeter). There is evidence to suggest the abandonment of Viroconium in around 520, perhaps in exchange for a more defendable location.

The Anglo-Saxon Conquest AD 550-600Southern Britain's Lost KingdomsAlthough its exact origins cannot be proven, Pengwern as an independent kingdom, or at least semi-autonomous subdivision of Powys, does appear to have been formed only in the sixth century, after the collapse of the Post-Roman central administration. It contained all of Powys' eastern territories. By AD 600 it seems to have been made up of three sub-kingdoms based on the cities of Caer Luit Coyt (now known as Wall, in southern Staffordshire), Caer Magnis, and Caer Guricon, and the first two had their own sub-kings. Originally, these would have been tributary to Powys, and then subsequently to the king of Pengwern.

The first king was a son of Brochfael Ysgythrog of Powys, so it seems the division was based upon the traditional Celtic practice of providing an inheritance for all sons, not just the eldest. Then, according to what little source material remains, in the early seventh century Morfael ap Glast, king of Glastenning, secured the eastern capital of Caer Luit Coyt during his lifetime. His younger brother secured the remainder of the territory upon the death of their father. The capital was moved to Llys Pengwern (the 'court of Pengwern'), perhaps for security reasons, and the kingdom survived as a bulwark against Anglian expansion in the Midlands until the mid-seventh century.

While the kingdom is usually known as Pengwern, it is uncertain whether this name was applied to the entire territory, being as it was the name of just one fort. The kingdom might just as well have been named after its last ruling dynasty, the Dogfeilion kings. However, Pengwern would have been a powerful name: 'gwern' would have been pronounced as 'wern' by the Romans, and would have been spelled 'vern' by them if it had been written down (unlikely, as it was local slang usage). The river that runs through the area, the Sabrina (modern Severn), probably had the letter 'b' mangled into a 'v' and then a 'w' by the local Cornovii/Gwynedd Britons. Then they dropped the 'Se' from the front of Severn, turning Severn into 'Vern', which they pronounced 'Wern', and then altered later into 'Gwern' as they came to do with any word beginning in 'w'. Also note that the original British name for the Severn was Habren - the 's' at the start was a Roman addition - so this would explain how the 's' was removed from the name - to the Britons it had not been there in the first place. That sort of mixed progression would occur only at places inhabited by Romans in numbers that were sufficient enough to influence the name. Such a concentration of Romans would have to be at the town of Viroconium. Then when the locals in that town fled up the river to Pengwern, they took their odd pronunciation with them (not even knowing that wern/gwern was the same word as Hefren). Pen means 'head' or 'source', so the local name became Pengwern, headwaters of the Severn, a strong and commanding name.

Another possible explanation for the name from Mak Wilson still gives 'pen' as 'head', but provides 'gwern' as the meaning of 'alder swamp'.

c.570 - 613

Mawn or Iago ap Brochfael?

First king of Pengwern. Sons of Brochfael Ysgythrog of Powys.

from 577

Pengwern's southern border comes under some pressure from the Hwicce, as the British kingdoms based around Caer Baddan, Caer Ceri and Caer Gloui fall. The defeat is a disaster for all Britons of the west of the country, as it also divides Pengwern and Gwent from Dumnonia and Caer Celemion.

584

Viroconium is sacked by the West Seaxe. The kingdom has very likely already relocated its capital before this event.

Roman Viroconium
The old Roman fort at Viroconium, one of their largest settlements, was substantially and skilfully rebuilt in timber between about 530-570, and then mostly dismantled by 600

603

Following a successful first meeting between the Roman Church based at Canterbury and the Celtic Church (the descendant of the former British Church of the Roman period), a second meeting is quickly arranged. This takes place at Abberley in Worcestershire, probably close to the border between the Hwicce and Pengwern. It is attended by seven bishops of the Celtic Church, along with many learned monks, mainly from Bangor-is-Coed (in Pengwern). The Britons are not impressed with Augustine's imperious manner and the meeting ends in disappointment for the Roman envoy.

c.612

This point marks the first appearance of the Dogfeilion of Gwynedd in Powys and Pengwern, although according to Edward Dawson, Pengwern remains part of Powys, and the courts of Pengwern and Caer Luit Coyt are Powysian courts. Given Welsh emphasis on ancestry to qualify for a throne, it seems likely that a Dogfeilion leader (probably Cyndrwyn Glas) had married a daughter of the king of Powys, qualifying his descendants to govern Powys by the rules of descent of Gwynedd (which had been inherited from their ancestors, the Pictish Venicones). Romans and Romano-British use primogeniture, but the Pictish rules are that any descendant, regardless of the form of that descent, is qualified to inherit (meaning that even bastard sons of wayward daughters can show up and claim a piece of a territory or even kingship). The fact that the Dogfeilion are accepted as rulers of Powys (and the part of Powys that is known as Pengwern) is very telling. There has to be a valid claim of descent.

c.612

Morfael ap Glast

King of Caer Luit Coyt (Eastern Pengwern) & Glastenning.

613

In one of the bloodiest and hardest fought battles of its time, several British kings form a coalition to halt Ęthelfrith of Bernicia at the Battle of Caer Legion (Chester). Iago of Gwynedd and Selyf of Powys are both killed, and the battle is a disastrous British defeat.

Bledric ap Custennin, king of Dumnonia, dies at the Battle of Bangor-is-Coed, which follows very soon afterwards. A certain Brochfael is named as the commander of Caer Legion at this time, and may be one of the sons of Powys' Brochfael, also the theoretical first king of Pengwern named above. After this, the Dogfeilion kings appear to move in on Pengwern. The monks of Bangor-is-Coed are present at the battle to pray for divine support, but they too are slaughtered (the act is seen as divine retribution for their refusal to help evangelise the English in 603).

613? - c.620?

Cyndrwyn Fawr

King of Pengwern.

? - 613 or c.620

Constantine

King of Caer Magnis. Brother of Cyndrwyn Fawr?

617

The fall of Elmet to the Bernicians of Edwin suddenly exposes the entire length of the northern border of both Pengwern and Mercia, making them likely next targets in the aggressive policy of Northumbrian expansion.

c.620 - 656

Cynddylan ap Cyndrwyn

Brother of Morfael ap Glast? Mentioned 642.

654/655

Pengwern's staunch ally, Penda of Mercia, defeats the East Engle at Blytheburgh, but is later killed by Oswiu of Northumbria at the Battle of Winwaed. Northern Mercia is annexed by Northumbria, leaving Pengwern vulnerable on the front line against an aggressive Anglian kingdom.

656

Caranfael ap Cynddylan

Son. May not have ruled.

656

Overrun by Oswiu of Northumbria, the royal family is destroyed and the kingdom terminated. This further exposes the border of Gwent and fully exposes Powys for perhaps the first time. Saxons migrate into the territory from the south to form the minor kingdoms of the Wrocenset and Magonset. These in turn are absorbed by Mercia by the eighth century.
