An early British kingdom that flourished between the fifth and ninth centuries and continued as a sub-kingdom of Scotland until the eleventh century. Along with Wales itself and West Wales or Cornwall, Strathclyde was one of the enclaves where Brythonic kings continued to hold sway.

Location

The south-west corner of modern Scotland, or roughly where the modern region of Strathclyde is today, except that at its fullest extent the kingdom of Strathclyde stretched from the Firth of Clyde in the north, to the river Derwent in Cumberland (encompassing what was once northern Rheged )

Name

Strathclyde may well have been the simply the name appended to the kingdom by the Scotti. The earliest historical references that do exist refer to the kings of Alt Cluid, Clyde Rock, the capital of the kingdom. To the local Brythonic speaking inhabitants it may have been known as Ystrad Clud, the valley of the Clyde, or possibly under a different name altogether.

History

The kingdom of Strathclyde evolved from the tribal territories of the Damnonii, themselves part of the confederation of northern tribes known as the Brigantes and was centred on the citadel of Alt Cluid. Ceretic Guletic is the first recorded king of Strathclyde, who ruled sometime in the mid to late fifth century, his appellation Guletic signifying his reputation as the founder of the kingdom.

From the genealogies preserved by their southern cousins in Wales we can derive something of the sequence of rulers but in truth the recorded history of Strathclyde is scant and fragmented. There are no surviving native records, and all we know comes from a few scattered references in the surviving Scottish and English records.

What we can say is Strathclyde's history was dominated by warfare and territorial struggle against neighbouring kingdoms; not only was there the struggle to remain independent in the face of Northumbria eager to extend its dominion northwards, there was also a three way struggle for dominance in the north with the kingdoms of Dal Riada and Pictavia.

The defeat at Nechtansmere in 685 effectively ended Northumbrian hopes of extending its control northwards, but in the struggle between the three northern kingdoms, kings came and went, battles were fought and lost, and sometimes Strathclyde and sometimes Dal Riada and sometimes Pictavia held the upper hand.

In the end it was the intervention of the Vikings in the ninth century that changed everything, playing a significant role in uniting Dal Riada and Pictavia under one king. The beginning of the end for Strathclyde was in the year 870 when As the Annales Cambriae recorded,

The fortress of Alt Cluid was broken by the gentiles
that is, stormed and captured by Olaf, the Viking king of Dublin. It is generally presumed that this was with at least the tacit support of Constantine I, then king of the united kingdoms of Dal Riada and Pictavia, as it is clear that Constantine I took this as an opportunity to extend his influence south over Strathclyde.

The reigning king of Strathclyde, Arthgal map Dumnagual was captured and taken to Dublin where he was eventually killed; his son Rhun map Arthgal, who had married one of the daughters of Kenneth mac Alpin and was therefore brother-in-law to Constantine I succeeded him.

Eochaid map Rhun is really the last British king of Strathclyde. He allied himself with Giric, one of the nephews of Kenneth mac Alpin, who had seized the crown of the Scots in 878. But a year later, Donald I had defeated them both and established himself as overlord of both the Scots and the Strathclyde Welsh. There is evidence to suggest that at most of the native nobility then fled south into exile in Gwynedd but Strathclyde seems to have continued as a semi-autonomous sub-kingdom of Scotland for another century or so with a (rather confused) king list of its own.

It is not until 1018, and the rule of the modernizer Malcolm II, and in particular his defeat of the English at the Battle of Carham and the consequent recovery of Lothian, that the notion of a separate Strathclyde disappeared, and became subsumed within the kingdom of Scotland.


In the period from the fifth and sixth centuries onwards, Scotland was divided into four kingdoms: Dalriada, Pictavia, Gododdin (Lothian), and Strathclyde. Strathclyde’s capital was at Dumbarton Rock, or Alt Cluid, on the Firth of Clyde. Dumbarton was attacked by Vikings in 870 AD, and seems to have ended its role as an independent kingdom shortly afterwards, around c900. This essay will look at the evidence which can be found regarding the events of this period.


As well as its fortress capital at Dumbarton, Strathclyde had a religious centre at Govan, and a royal residence at Partick, both of which are in modern-day Glasgow.


The Vikings had laid siege to Dumbarton for four months in 870, eventually defeating the inhabitants when they cut off their water supply. The Norse king Olaf returned to the Viking city of Dublin in 871, with two hundred ships full of slaves and looted treasures. Olaf came to an agreement with Constantine I, king of Scots, and Arthgal f Dyfnwal1, king of Strathclyde, was executed. Rhun f Arthgal, brother-in-law of Constantine, became king of Strathclyde, apparently as a client or sub-king of Constantine.


Rhun was to die c878, possibly in the same battle as Constantine, who was killed fighting the Norse. He was succeeded by Eochaid f Rhun, who allied himself with Giric f Dungal of the Scots. The two reigned jointly over Alba and Strathclyde until 889, when they were expelled, effectively ending Strathclyde’s status as an independent state, c890. Following their expulsion, Donald f Constantine became king of Strathclyde. This marked the merging of the kingships of the Scots from Dalriada and the Britons of Strathclyde. Strathclyde kept some independence, but its kingdom was essentially one subject to Scottish rule.


Strathclyde’s history beyond this point is at best sketchy, and this essay will continue by looking at the evidence which suggests that some of the Strathclyde nobility fled to Gwynedd in north Wales. Lands previously belonging to Strathclyde seem to have become a sub-kingdom under Scottish control.


The first source of evidence which refers to the exodus to Wales c890 is the Welsh Chronicle of the Princes:
“The men of Strathclyde, those that refused to unite with the English, had to depart from their country and go into Gwynedd.” 2


It should be noted that this source is not always seen as reliable, and that the “English” referred to are almost certainly in fact the Scots. On their arrival in Gwynedd, the Strathclyde Britons were welcomed by Anarawd of Gwynedd. They were soon to help him in battle against the Saxons.


It remains uncertain whether Eochaid travelled to Gwynedd with his people, since the date of his death is unknown, but other evidence supports and corroborates the possibility of a small group of Strathclyde nobility travelling to Gwynedd c890.


Firstly, the migration would explain the growth of the cult of St Kentigern in north Wales. Jocelin’s Vita Kentigerni tells a strange tale about a period of exile in Gwynedd for St Kentigern. There are dedications to him at St Asaphs and elsewhere in north Wales, and also many dedications in Cumbria.


Secondly, Glasgow remained obscure as the cult centre of St Kentigern, until it was revived by Earl David between 1113 and 1124. Perhaps this obscurity dated back to 890 and later years, although this may be ambitious, and is not borne out by the Inquisitio David. Jocelin’s Vita Kentigerni, however, might well date back to the eighth and ninth centuries in its earliest sections, which could perhaps have been written by a Glasgow scriptorium, active until the later ninth century, and folding with the Strathclyde exodus.


A third clue that would back up the migration theory is that the pedigree of Rhun f Arthgal has been preserved in Welsh lore. Other traditions relating to the ‘Men of the North’ may also have some bearing, and the ‘Welsh’ poetry of Y Gododdin might have travelled to Wales with the Strathclyde exiles.


Following the flight to Gwynedd, the Strathclyde kings seem to have been client or sub-kings of the kings of Scots. Donald f Aed, for instance, was definitely part of the royal Scottish dynasty, and some other Strathclyde kings may also have been. Strathclyde’s independence effectively came to an end with the death of Ywain (Owen) the Bald, who died in 1018, when the dynasty of Kenneth f Alpin began to rule the region.


The influence of the Norse in Strathclyde during the period from 870 onwards cannot be ignored. Five “hogback” house-shaped gravestones of Norse design are to be found at Govan Parish Church in modern-day Glasgow, a site that had religious importance for the Strathclyde kings. A road leads from the churchyard to Doomster Hill, a large earthen mound used as an assembly place, in a manner similar to that found at Tynwald in the Isle of Man, where, the church of St John is linked to the Manx parliament hill by a straight processional route. The links to the Norse kings of Man of the ninth and tenth centuries suggest a strong Norse influence in Strathclyde at that time.


In summary, then, this essay has looked at the evidence for events c900 which ended the independence of the kingdom of Strathclyde. We have looked at the Viking attack on Dumbarton in 870, and the evidence pointing to an exodus to Gwynedd in North Wales in the years following this event. This evidence includes the Welsh Chronicle of the Princes, the growth of the cult of St Kentigern in Wales, Glasgow’s obscurity as the cult’s centre, and the preservation of Rhun f Arthgal’s pedigree, and stories of the men of Strathclyde in Welsh lore and traditions, including the poem Y Gododdin. Following this exodus the kings of Strathclyde seem largely to have been subordinate sub-kings to the king of Scots, finally losing their independence in 1018.
