'''Dyfnwal ab Owain''' (died 975) was a tenth-century [[King of Strathclyde]].{{#tag:ref|Since the 2000s academics have accorded Dyfnwal various [[patronym]]s in English secondary sources: ''Domnall mac Eogain'',<ref>[[#B12|Busse (2006c)]].</ref> ''Dunmail map Owain'',<ref>[[#S11|Snyder (2003)]].</ref> ''Dwnwallon ab Owain'',<ref name="C10">[[#C10|Charles-Edwards (2013b)]].</ref> ''Dyfnwal ab Owain'',<ref>[[#M10|Minard (2012)]]; [[#C3|Clarkson (2010)]]; [[#BXX5|Breeze (2007)]]; [[#B12|Busse (2006c)]]; [[#M6|Minard (2006)]]; [[#T5|Thornton (2001)]].</ref> and ''Dyfnwal map Ywain''.<ref name="M1">[[#M1|Macquarrie (2004a)]].</ref> Likewise, since the 1990s academics have accorded Dyfnwal various personal names in English secondary sources: ''Domnaldus'',<ref>[[#DZZ1|Downham (2007)]]; [[#D3|Downham (2003)]].</ref> ''Domnall'',<ref>[[#BZZ1|Busse (2006b)]]; [[#B12|Busse (2006c)]].</ref> ''Donald'',<ref>[[#K2|Keynes (2015)]]; [[#M4|McGuigan (2015b)]]; [[#W10|Williams (2014)]]; [[#W14|Walker (2013)]]; [[#M10|Minard (2012)]]; [[#BXX5|Breeze (2007)]]; [[#M6|Minard (2006)]]; [[#B4|Broun (2004a)]]; [[#M3|Macquarrie (2004b)]]; [[#D2|Duncan (2002)]]; [[#W16|Williams; Smyth; Kirby (1991)]]; [[#H2|Hudson (1994)]].</ref> ''Dovenald'',<ref>[[#C14|Clarkson (2014)]].</ref> ''Dufnal'',<ref>[[#M10|Minard (2012)]]; [[#M6|Minard (2006)]]; [[#J2|Jayakumar (2002)]]; [[#W16|Williams; Smyth; Kirby (1991)]].</ref> ''Dumnagual'',<ref>[[#D2|Duncan (2002)]].</ref> ''Dunguallon'',<ref>[[#H3|Hicks (2003)]]; [[#D2|Duncan (2002)]].</ref> ''Dunmail'',<ref>[[#C1|Cannon (2015)]]; [[#W13|Williams (2004c)]]; [[#BXX5|Breeze (2007)]]; [[#S11|Snyder (2003)]].</ref> ''Dunwallon'',<ref>[[#M9|Matthews (2007)]].</ref> ''Dyfnal'',<ref>[[#BXX5|Breeze (2007)]]; [[#H5|Hudson (1996)]]; [[#H12|Hudson (1991)]].</ref> ''Dyfnwal'',<ref>[[#B1XXX|Broun (2015a)]]; [[#E2|Edmonds (2015)]]; [[#K2|Keynes (2015)]]; [[#C14|Clarkson (2014)]]; [[#E1|Edmonds (2014)]]; [[#C10|Charles-Edwards (2013b)]]; [[#C7|Clarkson (2012a)]]; [[#M10|Minard (2012)]]; [[#O2|Oram (2011)]]; [[#C3|Clarkson (2010)]]; [[#W4|Woolf (2009)]]; [[#BXX5|Breeze (2007)]]; [[#DZZ1|Downham (2007)]]; [[#W1|Woolf (2007)]]; [[#B12|Busse (2006c)]]; [[#M6|Minard (2006)]]; [[#B11|Broun (2004d)]]; [[#M1|Macquarrie (2004a)]]; [[#M3|Macquarrie (2004b)]]; [[#H3|Hicks (2003)]]; [[#T5|Thornton (2001)]]; [[#M2|Macquarrie (1998)]]; [[#W8|Woolf (1998)]] p. 190; [[#H2|Hudson (1994)]].</ref> ''Dyfnwallon'',<ref>[[#W1|Woolf (2007)]]; [[#H3|Hicks (2003)]]; [[#C16|Clancy (2002)]]; [[#M2|Macquarrie (1998)]].</ref> and ''Dwnwallon''.<ref name="C10"/>|group=note}} He was a son of [[Owain ap Dyfnwal (fl. 934)|Owain ap Dyfnwal, King of Strathclyde]], and seems to have been a member of the royal dynasty of Strathclyde. At some point in the ninth- or tenth century, the [[Kingdom of Strathclyde]] expanded substantially southwards. As a result of this extension far beyond the valley of the [[River Clyde]], the realm became known as the [[Kingdom of Cumbria]]. By 927, the kingdom seems to have reached as far south as the [[River Eamont]].

Dyfnwal appears to have reigned between the 930s and the 970s. He is first attested in the 940s, when he is recorded associated with the ecclesiast [[Cathróe of Metz|Cathróe]] on the latter's journey to [[Continental Europe]]. At the midpoint of the decade, the Cumbrian kingdom was ravaged by the forces of [[Edmund I|Edmund, King of the English]]. Two of Dyfnwal's sons are said to have been blinded by the English, which could indicate that Dyfnwal had broken a pledge to his southern counterpart. One possibility is that he had harboured insular Scandinavian opponents of Edmund. The latter is recorded to have handed over control of the Cumbrian realm to [[Máel Coluim mac Domnaill, King of Alba]]. How much authority the Scots enjoyed over the Cumbrian realm is uncertain.

In 971, the reigning [[Cuilén|Cuilén mac Illuilb, King of Alba]] was slain by [[Rhydderch ap Dyfnwal]]. At some point after this act, Cuilén's eventual successor, [[Cináed mac Maíl Choluim|Cináed mac Maíl Choluim, King of Alba]], is recorded to have penetrated deep into Cumbrian territory, possibly as a retaliatory act. The following year, the reigning [[Edgar, King of the English]] held a remarkable assembly at [[Chester]] which numerous northern kings seem to have attended. Both Dyfnwal and his son, [[Máel Coluim, King of Strathclyde|Máel Coluim]], appear to have attended this assembly. The latter is styled King of the Cumbrians in the context of this meeting, which might indicate that Dyfnwal had previously abdicated the throne.

Dyfnwal is recorded to have died in 975 whilst undertaking a pilgrimage to [[Rome]]. Quite when he gave up the throne is unknown. One possibility is that Rhydderch had succeeded him before the killing of Cuilén. Another possibility is that the apparent retaliatory raid by Cináed marked the end of Dyfnwal's kingship. It is also possible that he held on to power until 973 or 975. In any event, Máel Coluim appears to have been succeeded by another son of Dyfnwal named [[Owain ap Dyfnwal (died 1015)|Owain]], who is recorded to have died in 1015. The later [[Owain Foel, King of Strathclyde]], who is attested in 1018, may well be a grandson of Dyfnwal. Dyfnwal is likely the [[eponym]] of [[Dunmail Raise]] in England, and possibly [[Cardonald]] and [[Dundonald, South Ayrshire|Dundonald]]/[[Dundonald Castle]] in Scotland.

==Cathróe amongst the Cumbrians==

Dyfnwal is attested by the tenth-century ''Life of St Cathróe'', which appears to indicate that he was established as king by at least the 940s. According to this source, when [[Cathróe of Metz|Cathróe]] left the realm of [[Custantín mac Áeda, King of Alba]] at about this time, he was granted safe passage through the lands of the Cumbrians by Dyfnwal because the two men were related. Dyfnwal thereupon had Cathróe escorted through his kingdom to the frontier of the Scandinavian-controlled Northumbrian territory.<ref>[[#E3|Evans (2015)]] p. 150; [[#K2|Keynes (2015)]] p. 111; [[#M4|McGuigan (2015b)]] p. 98; [[#M5|Molyneaux (2015)]] p. 24, 24 n. 30; [[#C14|Clarkson (2014)]] chs. 1 ¶ 25, 6 ¶¶ 4–5; [[#E1|Edmonds (2014)]] pp. 205–206; [[#W14|Walker (2013)]] ch. 3 ¶ 51; [[#C7|Clarkson (2012a)]] ch. 10 ¶ 25; [[#C3|Clarkson (2010)]] ch. 9 ¶ 24; [[#B11|Broun (2004d)]] p. 127; [[#M1|Macquarrie (2004a)]]; [[#M3|Macquarrie (2004b)]]; [[#D3|Downham (2003)]] p. 27; [[#M2|Macquarrie (1998)]] pp. 15–16; [[#W8|Woolf (1998)]] p. 190; [[#H2|Hudson (1994)]] p. 174 n. 8; [[#A1|Anderson, AO (1922)]] p. 441; [[#S3|Skene (1867)]] p. 116; [[#C4|Colganvm (1645)]] p. 497 § xvii.</ref> The ''Life of St Cathróe'' locates this southern frontier to the {{lang|la|civitas}} of {{lang|la|Loida}}.

Although the Wendover version of ''Flores historiarum'' alleges that Máel Coluim mac Domnaill was given Cumbrian territory to hold as a fief from the English, the terminology employed by the more reliable ''Anglo-Saxon Chronicle'' seems to suggest that Edmund merely surrendered or granted the region to him,<ref>[[#H11|Halloran (2011)]] p. 307; [[#W1|Woolf (2007)]] pp. 183–184.</ref> or that he merely recognised certain rights of the Scots in the region (such as the right to tribute).<ref>[[#M4|McGuigan (2015b)]] pp. 139–140; [[#D11|Davidson (2002)]] p. 115 n. 32; [[#H2|Hudson (1994)]] pp. 84–85.</ref> Edmund, therefore, may have allowed his Scottish counterpart to collect tribute from the Cumbrians in return for keeping them in check and for lending Edmund military assistance.<ref>[[#C14|Clarkson (2014)]] ch. 6 ¶ 20.</ref> It is possible that the territory in question corresponds to the region around [[Carlisle, Cumbria|Carlisle]]—roughly modern-day [[Cumberland]]—which in turn could reveal that the Scots were already in possession of the kingdom's more northerly lands.<ref>[[#D2|Duncan (2002)]] p. 23.</ref> It is conceivable that the Scots were allowed authority over Cumbrian territory because it was too far to be overseen effectively by the English themselves.<ref>[[#C14|Clarkson (2014)]] ch. 6 ¶ 20; [[#W1|Woolf (2007)]] p. 184.</ref> As such, it may have been recognised that the Cumbrian territories were situated within the Alpínid sphere of influence rather than that of the Cerdicings.<ref>[[#D11|Davidson (2002)]] p. 116, 116 n. 36.</ref> In any event, it is uncertain what authority Máel Coluim mac Domnaill enjoyed over the Cumbrians.

There is also reason to suspect that a man other than Dyfnwal ruled as king in the wake of Edmund's 945 campaign.
