ap BLEDDRI versus SONS OF RHODRI MAWR
By Darrell Wolcott
"Hyfaidd, with all the inhabitants of the kingdom of Dyfed, driven by the might of the sons of
Rhodri, had submitted himself to King Alfred's royal overlordship." 
Bishop Asser, an intimate companion of Alfred the Great of Wessex (871-899) , used the above
statement to describe the situation in south Wales as it existed about the year 880. He did not, however, give us any
details concerning the reasons for Hyfaidd's contention with the sons of Rhodri, but seems to infer that Hyfaidd was the innocent
victim of oppression by the Gwynedd brothers. We think Asser knew only what Hyfaidd had told King Alfred about the problem,
and he never interviewed Anarawd, Cadell and Merfyn to hear their side of the dispute. Subsequent events tell us that the
king not only DID obtain both sides of the story, but imposed a settlement that both sides readily accepted.
Before we examine this dispute and settlement more closely, we should first describe the principal
men involved and the situation in Wales as they would have seen it:
KINGDOM OF DYFED:
Hyfaidd ap Bleddri was, as we chart the family, paternally descended from Dyfnwallon ap Arthgen,
King of Ceredigion.  Bleddri had married the heiress of the king of Dyfed when that Royal Family daughtered-out after
ruling almost 400 years. Our charts show:

The kingdom of Dyfed, which,
in the late 8th century, consisted roughly of the present Pembrokeshire and Carmarthenshire , had been ruled for over 300
years by men who descended from the Irish Deisi tribe. By the middle of the 9th century, Dyfed was being ruled by men paternally
descended from the Ceredigion Royal family.
There were other important
Deisi families in Dyfed, which had branched off the Royal line in the early 700's that spawned a number of well-known
noblemen in the 10th and 11th centuries , but were not in the line of royal succession.
THE KINGDOM OF CEREDIGION:
Seisyll ap Clydog, a direct male
descendant of Ceredig ap Cunedda, was the king of Ceredigion about the year 740. His kingdom then consisted of the 6
commotes north of the Aeron valley, now called Uwch Aeron. He seized from Dyfed, the kingdom directly to his south,
the 4 commotes now known as Is Aeron. He may have called the new group of 10 commotes by the name Seisyllwg, but within
a generation it was simply an expanded Ceredigion. We think he also moved his official court to a new location in the
conquered territory, probably near where the later Cardigan Castle was erected.
The grandson of king Seisyll,
Dyfnwallon ap Arthgen, had two sons. The younger son, Bleddri, married the heiress of Dyfed. Meurig ap Dyfnwallon,
the eldest brother and eventual king of Ceredigion, was succeeded by a son, Gwgan. The sister of Gwgan, Angharad, was
married to a new Gwynedd king called Rhodri ap Merfyn  about 849, as a part of a new military alliance to field an army
large enough to meet their enemies in set battle.
King Gwgan was drowned
in 872 and the seeds were sown for the conflict we mentioned in our opening paragraph. While that king died childless,
there was a distant cousin line which had earlier branched off the Royal family.  The kingship of Ceredigion simply shifted
to that family, but there was no heir to the lands which had been personally owned by King Gwgan, except his sister, Princess
Angharad. At least that was the position taken by her husband, King Rhodri Mawr of Gwynedd.
Gwgan's extended family
thought otherwise. Hyfaidd ap Bleddri was the eldest first-cousin of Gwgan, and he believed that he was the nearest
male heir and that land did not lawfully descend through females unless there were no eligible males to inherit. Rhodri,
we believe, told Hyfaidd that if he set foot on any of his wife's land without invitation, that the next time they met, Rhodri
would be riding at the head of the entire Gwynedd army. Hyfaidd may have grumbled a bit, but he bowed to the threat.
The king of Ceredigion apparently declined to insert himself between the rulers of these much larger kingdoms, so long as
he received his legal assessments from the disputed lands.
THE DISPUTE IS REBORN:
Barely 6 years later,
Rhodri fell in a battle in Gwynedd against Saxon invaders. Hyfaidd wasted little time in seizing one of the manors formerly
held by his cousin, Gwgan. The sons of Rhodri were yet men in their 20's and unproved on a battlefield where their father
was absent. But their first raid into Ceredigion was sufficiently impressive to deprive Hyfaidd of any revenue from the disputed
lands. But when the Gwynedd brothers returned home to defend it against further Saxon incursions, Hyfaidd renewed his
efforts to extract rents from the disputed Ceredigion land.
About 880, the adult sons
of Rhodri Mawr went south to lay waste to Dyfed lands which were clearly subject to King Hyfaidd's rule. This policy
of "if you keep claiming our mother's lands, we will devastate your subjects' lands" resulted in the leading men of Dyfed
demanding that their king protect their homes. Thus, Hyfaidd turned to Wessex King Albert, placing Dyfed under that
monarch's protective custody. Albert already held the over-lordship of Brycheiniog, Gwent and Glywysing, each of whom had
asked for protection from Danish raiders. 
King Alfred invited the
Gwynedd brothers to his court to learn why they were harrassing Hyfaidd's lands and what he could do to restore peace between
the two parties. After considering both sides of the dispute, Alfred proposed a settlement on these terms: Hyfaidd
would withdraw any inheritance claims to Angharad's lands in Ceredigion, and the brothers would marry ladies of Hyfaidd's
family so that their children would inherit the disputed Ceredigion lands as one big extended family.
Hyfaidd had 2 daughters,
one now age 14 and the other age 10. He also had a niece, the daughter of his wife's brother, who was about age 15.
The two oldest ladies would immediately be wed to Anarawd and Cadell, respectively, while the younger lady would be engaged
to Merfyn, with that marriage deferred until she turned 14. Both sides agreed to these terms and peace was restored
in Dyfed. The youngest son of Rhodri, Tudwal, was barely 14 years old and was not involved in either the dispute nor
the settlement agreement.

statements, they should not be considered "history" but merely our attempt to determine what must have occurred to produce
the actual results which ARE recorded.
