''. The work relates that a force of 300 distinguished warriors from across the Brittonic world assembled at Din Eidyn for a raid on
Catraeth (probably
Catterick) around AD 600. The poem's dense language and convoluted history make it difficult to interpret the historical events underlying the work. According to
Ifor Williams' interpretation, the warriors were summoned by
Mynydawc Eidyn, perhaps a Gododdin ruler, to attack the Angles holding Catraeth. The warriors feasted for a year before setting out on the expedition, during which almost all were killed. Later scholars such as John Koch and Graham Isaac have challenged elements of this interpretation, and read ''Mynydawc'' as a place name referring to a mountain, not as a ruler. Koch suggested that the Eidyn ruler was Ureui or Gwylget Gododdin, who are mentioned in the text.

In the 7th century, the Gododdin kingdom was in decline. At this time, Eidyn may have been a sub-kingdom within Gododdin, and its lords may have controlled only their own territory, and not all of Gododdin. The

(roundhouse). In this period, Castle Rock was apparently one of the major centres of the Votadini, though it was dwarfed by
Traprain Law, which was ten times larger.
In the early medieval period, Din Eidyn emerged as the principal political centre of the Gododdin kingdom, especially after the abandonment of Traprain Law in the early 5th century. In the 7th century, when the Gododdin kingdom was in decline, the lords of Din Eidyn may have only controlled only the Eidyn district rather than the entire Gododdin territory. Following the Anglian conquest of Eidyn, the Din Eidyn location remained a fortified settlement of the Angles, and later of the Scots.
Legacy

Eidyn remained prominent in Brittonic tradition long after its conquest by the Angles. Several works invoke Eidyn's position as the northern frontier of the Britons. The poem ''
Pa gur yv y porthaur?'' (''What man is the gatekeeper?''), dating to the 10th century or earlier, contains several allusions to
