''): "". There is reason to suspect that Rhydderch was a son of
Dyfnwal ab Owain, King of Strathclyde. Although there is no specific evidence that Rhydderch was himself a king, the fact that Cuilén was involved with his daughter, coupled with the fact that his warband was evidently strong enough to overcome that of Cuilén, suggests that Rhydderch must have been a man of eminent standing. At about the time of Cuilén's demise, a granddaughter of Dyfnwal could well have been in her
teens or
twenties, and it is possible that the recorded events refer to a visit by the King of Alba to the court of the
King of Strathclyde. and could indicate that Rhydderch was compelled to fire his own hall. Certainly, such killings are not unknown in Icelandic and Irish sources. The Lothian placename of
West Linton appears as in the twelfth century. The fact that the place name seems to refer to a man named Rhydderch could indicate that this was the place where Cuilén and Eochaid met their end. Another possible scenario concerns the record of Cuilén's father's seizure of
Edinburgh preserved by the
Chronicle of the Kings of Alba, a conquest which would have included at least part of Lothian. The records that appear to locate Cuilén's fall to Lothian, therefore, could indicate that he was in the midst of exercising overlordship of this debatable land when Rhydderch seized the chance to exact revenge upon the abductor of his daughter. as it appears on folio 33v of Oxford Bodleian Library Rawlinson B 489 (the
Annals of Ulster). Irish sources accord him the title ('King of the Britons'). It is unknown if Rhydderch was himself a king. Certainly, the
Annals of Ulster accords Dyfnwal's son and successor,
Máel Coluim, the title ('King of the Northern Britons'). Rhydderch is only attested in sources outlining Cuilén's demise and is not heard of again. Cuilén was succeeded by
Cináed mac Maíl Choluim, a fellow member of the
Alpínid dynasty. One of Cináed's first acts as King of Alba was evidently an invasion of the
Kingdom of Strathclyde. This campaign could well have been a retaliatory response to Cuilén's killing, carried out in the context of crushing a British affront to Scottish authority. Whatever the case, Cináed's invasion ended in defeat, a fact which coupled with Cuilén's killing reveals that the Cumbrian realm was indeed a power to be reckoned with. According to the
Chronicle of the Kings of Alba, Cináed constructed some sort of fortification on the
River Forth, perhaps at the strategically located Fords of Frew near
Stirling. One possibility is that this engineering project was undertaken in the context of limiting Cumbrian incursions. Whilst it is conceivable that Rhydderch could have succeeded Dyfnwal by the time of Cuilén's fall, another possibility is that Dyfnwal was still the king, and that Cináed's strike into Cumbrian territory was the last conflict of Dyfnwal's reign. In fact, Dyfnwal's son
Máel Coluim seems to have taken up the Cumbrian kingship by 973, as evidenced by the latter's act of apparent submission to
Edgar, King of the English that year. an otherwise unknown name that may be the result of textual corruptions. ==Notes==
