Rhun ab Arthgal explained

Rhun ab Arthgal
Succession:King of Strathclyde
Predecessor:Arthgal ap Dyfnwal
Father:Arthgal ap Dyfnwal
Issue:

Rhun ab Arthgal was a ninth-century King of Strathclyde. He is the only known son of Arthgal ap Dyfnwal, King of Alt Clut. In 870, during the latter's reign, the fortress of Alt Clut was captured by Vikings, after which Arthgal and his family may have been amongst the mass of prisoners taken back to Ireland. Two years later Arthgal is recorded to have been slain at the behest of Causantín mac Cináeda, King of the Picts. The circumstances surrounding this regicide are unknown. The fact that Rhun seems to have been Causantín's brother-in-law could account for Causantín's interference in the kingship of Alt Clut.

The Viking destruction of the capital fortress of the Kingdom of Alt Clut appears to have brought about a reorientation of the kingdom towards the valley of the River Clyde. In consequence, the realm came to be known as the Kingdom of Strathclyde. Either Rhun or his father could have been the first kings of Strathclyde. In the years following the fall of Alt Clut, Rhun's realm may have endured periods of Pictish and Viking overlordship. Despite his kinship with the Pictish king, there is reason to suspect that the two clashed at some point.

It is unknown when Rhun's reign came to an end or when he died. One possibility is that he fell with Causantín, who seems to have been killed warring against the Vikings in 876. Certainly, Rhun's son, Eochaid, is recorded to have succeeded Causantín's successor, Áed mac Cináeda, King of the Picts, after 878. Whether Eochaid's succession reflects the end of Eochaid's reign and life is unknown.

Family

Rhun's patrilineal ancestry is evidenced by a pedigree preserved within a collection of tenth-century Welsh genealogical material known as the Harleian genealogies. According to this source, Rhun was a son of Arthgal ap Dyfnwal, King of Alt Clut, and descended from a long line of kings of Alt Clut.[1] Rhun is Arthgal's only known son.[2]

In about 849, the ninth- to twelfth-century Chronicle of the Kings of Alba reports that Britons burned Dunblane, an ecclesiastical centre seated on the southern Pictish border.[3] This attack took place during the reign of Cináed mac Ailpín, King of the Picts,[4] and may have been overseen by either Arthgal[5] or his father, Dyfnwal ap Rhydderch.[6] The razing of Dunblane could be evidence that the Kingdom of Alt Clut was in the process of extending its authority at the expense of the Pictish regime. If so, the British kings would appear to have seized upon the chaos wrought by contemporaneous Viking attacks upon the Picts.[7]

According to the Chronicle of the Kings of Alba, Rhun was married to a daughter of Cináed.[8] This alliance may have been contracted between the Britons and Picts as a way of repairing international relations following the attack on Dunblane in 849.[9] Rhun is the last listed king in the Harleian pedigree.[10] This could indicate that the genealogy was originally compiled during his floruit[11] —perhaps at the time of his marriage to his Alpínid wife, or upon the outset of his reign as king.[12] According to the Chronicle of the Kings of Alba, a product of the marriage was a son named Eochaid.[13] The twelfth-century Prophecy of Berchán describes Eochaid as "the son of the woman from Dún Guaire".[14] The fact that ninth-century Historia Brittonum identifies Bamburgh as Din Guoaroy could indicate that Dún Guaire too refers to Bamburgh.[15] Another possibility is that Dún Guaire refers to one of two similarly-named sites in the Hebrides (on Mull and Islay),[16] In any event, the association of Rhun's wife with the fort could be evidence that she had been previously married.[17]

King of Alt Clut

In 870, during the reign of Rhun's father, the fortress of Alt Clut was captured and destroyed by the insular Scandinavian kings Amlaíb and Ímar, following a naval blockade of four months.[18] In the following year, the twelfth-century Chronicon Scotorum,[19] the fifteenth- to sixteenth-century Annals of Ulster,[20] and the eleventh-century Fragmentary Annals of Ireland reveal that Amlaíb and Ímar returned to Ireland with a fleet of two hundred ships, and a mass of captives composed of English, Britons, and Picts.[21] The exportation of these people to Ireland is also attested by Annales Xantenses, a ninth-century German source.[22] The captives could have been meant for ransom,[23] or may have been intended for the Dublin slave market.[24] It is possible that Arthgal and his family were amongst those imprisoned.[25]

Arthgal died in 872.[26] The Annals of Ulster[27] and Chronicon Scotorum reveal that he was slain at the behest of Causantín mac Cináeda, King of the Picts.[28] If Rhun succeeded Arthgal—as seems likely[29] —it is uncertain how long he outlived him.[30] Although the circumstances surrounding Arthgal's assassination are unknown,[31] the familial relationship between Causantín and Rhun could be evidence that Arthgal's demise was orchestrated to allow Rhun to gain the throne.[32] One possibility is that Rhun had been exiled from his father's realm, and had been living at the Pictish royal court when his father's realm was overcome by Amlaíb and Ímar.[33] This could mean that Causantín acted to offset any rival Rhun had in regard to the British kingship.[34] Conversely, if there was no strife between Rhun and Arthgal, Causantín's actions against the latter may have been carried out in the context of an intrusive and aggressive neighbour.[33] Arthgal's elimination may have been carried out in the context of an attempt by Causantín to capitalise upon the political turmoil wrought by the Viking onslaught.[35]

Another possibility is that, following the conquest of Alt Clut, Arthgal ruled as a puppet king under Amlaíb and Ímar. Certainly, the Vikings utilised royal puppets in the conquered kingdoms of Northumbria and East Anglia. If so, it could explain Causantín's role in Arthgal's demise, and could explain why his brother-in-law (or future brother-in-law) eventually succeeded to the throne.[36] In any event, Arthgal's elimination at Causantín's instigation would appear to have rid the latter of a neighbouring adversary, and would have also increased his own authority and reputation.[37]

Although the Harleian pedigree identifies the listed rulers as those of the Kingdom of Alt Clut,[38] it is apparent that one aftereffect of the destruction of the eponymous fortress was that the capital of the realm shifted up the River Clyde to the vicinity of Govan[39] and Partick.[40] Whilst Govan—seated on the Southern bank of the River Clyde—appears to have been utilised by Arthgal and Rhun's eighth-century predecessors,[41] Partick—situated on the Northern bank—could well have been used at least a century earlier.[42]

The relocation is partly exemplified by a shift in royal terminology. Until the fall of Alt Clut, for example, the rulers of the realm were styled after the fortress; whereas following the loss of this site, the Kingdom of Alt Clut came to be known as the Kingdom of Strathclyde in consequence of its reorientation towards Ystrat Clut (Strathclyde), the valley of the River Clyde.[43] Arthgal himself is styled King of the Strathclyde Britons upon his death in 872[44] —the first use of this terminology by Irish sources.[45] Although it is possible that Arthgal ultimately met his end in Ireland at the hands of his Viking captors,[46] this title could instead be evidence that he had briefly ruled the new Kingdom of Strathclyde.[33] Either he or Rhun could have been the first monarch to rule this reconstructed realm.[47]

King of Strathclyde

Rhun's reign probably commenced not long after his father's death, in 872.[48] The Chronicle of the Kings of Alba identifies Rhun as Latin: rex Britannorum ("king of the Britons").[49] Hostility between Rhun and his brother-in-law may be evidenced by the Prophecy of Berchán.[50] According to this source, Causantín won four victories over his enemies. Whilst the first three victories are stated to have been won against Vikings, the fourth is described as that of Latin: Cath Lures—a location possibly identical to Glasgow—where he overcame the "king of the Britons of the green mantles".[51] Although it is possible that the unnamed king in question was Arthgal—which could in turn cast light upon this man's demise[52] —another possibility is that the prophecy refers to Rhun himself. If Rhun is indeed the prophecy's mantled monarch, his conflict with Causantín may have occurred in the aftermath of his father's demise, and may have been undertaken in an attempt to ensure his kingdom's independence from Pictish overlordship.[50]

If a garbled passage preserved by the Chronicle of the Kings of Alba is to be believed, Amlaíb was killed by Causantín in 872/874/875, whilst in the midst of extracting tribute from the Picts.[53] Upon Ímar's death in 873, the Annals of Ulster styles him "king of the Northmen of all Ireland and Britain",[54] a title that may partly exemplify Viking overlordship of regions inhabited by the Picts, Strathclyde Britons, and the Welsh.[55] In 875, seemingly during Rhun's reign,[56] the Chronicle of the Kings of Alba reports that the Picts suffered a devastating loss to insular Scandinavians at Dollar after which the invaders are said to have occupied the vicinity for one year.[57] This Viking conquest—seemingly corroborated by the Annals of Ulster[58] —may be related to the campaigns of Hálfdan against the Picts and Strathclyde Britons in 875/876, as recorded by the ninth- to twelfth-century Anglo-Saxon Chronicle.[59] This northern campaigning by Hálfdan could have been conducted in the context of the insular Scandinavians not only avenging Amlaíb's killing but of regaining Ímar's authority in the region.[60] At any rate, these clashes with the Britons seem to show that the Kingdom of Strathclyde was not permanently subjected.[61] } Another son of Rhun could have been Dyfnwal, who ruled the Kingdom of Strathclyde into the second decade of the tenth century.[62]
