Post-Roman Britain


by Edward Dawson, 29 January 2012

The exact boundaries of the kingdom of Elmet at any particular time cannot be known for certain.

Much, however, can be deduced from the names used in the region. Much can also be deduced from economic and military realities, and indeed as these relate to the terrain.

First let us be clear about rivers. Rivers are not barriers and therefore not solid borders; they are in fact often used for travel and moving goods. River valleys therefore can be regarded as single possessions of their controlling rulers or owners.

Britain of the Dark Age was in the middle of a downturn in temperatures and an increase in cold and rain across northern Europe. Uplands which had been arable during the Roman Warm Period became useable only for grazing, and poor grazing at that. The control of river valleys where grain (early wheat varieties, and barley) could be planted were vital for survival. Therefore any river valley was controlled on both banks of the river, unless marshes (as in the case of the lower Trent) made the area impassable an/or unusable.

The north-eastern border of Elmet is fairly certain to have roughly followed a line along the River Wharfe [which is shown on the map below flowing through Calcaria and Olicana].

Borders on the map are conjectural.

Map of Elmet

The question is, who controlled that river valley? Given its proximity to Eborac [Ebrauc] (modern York), and the fact that a forest lay between it and the royal residence of Elmet, there is a good chance that it belonged to the British in Eborac before Eborac fell to the Angles of Diera. If not, then it was almost certainly to have been settled by the Angles before Elmet fell.

Therefore the conclusion can be drawn that the main border of northern Elmet was the Forest of Elmet [shown here separating Loidis from Calcaria], and also the marshes which stretched from the east of the forest to the River Don.

Olicana (known today as Ikley), and Calcaria (modern Tadcaster) downriver from it, show altered British/Roman names. From this it can be guessed that they were perhaps inhabited by Britons, although they were definitely under Deiran control [by the late sixth century]. There is of course a possibility that an armed truce existed between Diera and Elmet, allowing each to till their side of the river. This would be therefore an economic border of sorts but would not prevent raiding by either side. The effective military border of Elmet would be the Forest of Elmet just south-west of the river.

Looking at the map, the deep pink area is what should be regarded as the probable extent of Elmet in its final twenty years, the period between the death of its great champion, Madoc, at Catterick in 598, and the fall of Elmet when Edwin invaded in 617. [1]

This deep pink area contains many names of Romano-British origin, some of them containing the name of the region in various forms, and including the largest city in the area today: Leeds.

Note that it was in the general proximity of the River Idle [which today flows into the Trent, but until 1628 joined the Don close to Hatfield Chase], that Northumbrian King Aethelfrith was patrolling in 616. Presumably this was along the edge of his territory, and it was here that he encountered the East Angle army (under King Raedwald and his new friend Prince Edwin of Deira) and was killed. This then, in the vicinity of the Idle and Don rivers, would have been the south-east border of Elmet in its final years, a nation that was already tributary to Northumbria.

(The king of Elmet had murdered his guest Prince Hereric of Deira, undoubtedly at Aethelfrith's command. This automatically placed 'King' [magistrate] Ceredig ap Gwallog subordinate to Aethelfrith. A ruler is supreme, and to obey another is to become subservient to that other. This made Elmet part of Aethelfrith's domain, which he was patrolling. In that sense alone we can date the 'fall' of Elmet as an independent kingdom to the death of Hereric.)

The deep pink area of the map is full of Brythonic names and combined forms, such as Leeds, Doncaster, Burton Salmon, Ecclesfield, Ledsham, Ledston, Barwick-in-Elmet and Sherburn-in-Elmet.

The lighter, carnation pink area is made up of uplands, marshes, swamp, fens and fen carr (wet forest). This would be marginal land not controlled by the Angles, but only marginally inhabited by Britons, such as at Misson, a town still bearing the district's name to this day. [2]

[1] Edwin chased the king and his knights to the River Don in 617, where they finally stood and fought for a while. This would be the action of an army forced to the border of its country, and to go farther would be to leave that country.

As you can see, this pink wetlands merges into light grey wetlands as it nears the Trent, a river that appears to have been controlled in a military sense on both banks by the Angles in its upper valley (south of the River Idle), but which was too marshy for the Angles to want to settle on both banks north of the Idle.

Remnant British settlements seemed to continue there, such as Burton upon Stather (a 'burton' is a word often used by the Saxons/English to refer to a British settlement - ignore the conventional explanation of burh+tun). Anglian settlement seems to have reached north as far as Littleborough (in Nottinghamshire) on the west bank, and Gainsborough at a ford on the east bank. Ergo, Britons lived in the pink-grey mixed region, but were probably under the overlordship of the Angles of Lindsey.

The light grey block of colour on the map is the probable extent of British territories which possibly became Elmet, soon after that departure of the Roman legions in AD 409, although it cannot be said for certain to which kingdom it all belonged. It might have been part of Elmet; and there is a good chance of this. Or it may have been included in the Southern Pennines kingdom. We are assuming here that it was part of early Elmet, but that might not be correct. The presence of Anglian settlements with Anglian names along both banks of the upper Trent and deep into the territory, such as Nottingham, Sheffield and Balderton, point to an early takeover of the river valley and arable land to the Pennines by the Angles of Lindsay or Mercia. Indeed, the grey area is full of Germanic names for towns, much more so than Brythonic.

Another consideration is ethnic identity. Though all were under Roman rule, tribal identity appears to have survived into the post-Roman dark ages.

The Britons in the deep pink area seem to have been Brigantes. The Britons in the grey area were definitely Coritani. The Britons in the mountains (South Pennines) just west of the grey area were also Coritani. This would be another pointer toward the possibility that the grey area was part of South Pennines and not Elmet at all.

Aberford entrenchments
The Aberford entrenchments consist of three individual earthworks: the Becca Banks and the Ridge, plus the South Dyke, and the Woodhouse Moor Rein. According to dendro-dated wood deposits, they were probably built in the sixth century, or at least repaired

[2] For the sake of convenience, the whole district around Misson is given that name here, due to the existence of other, similar names in the region, and on both sides of the river: Misson, Misterton and Messingham. Since the Anglo-Saxon '-ing' ending appears to be the normal substitution for the Brythonic '-ion' or '-on', then the original name of that town appears to have been Messon or Mession. Given that '-ion/-on' is a Brythonic plural it implies that a tribe or sub-tribe of the name Miss or Mess lived there. Modern Welsh uses '-ion' but Brythonic/ Old Welsh and Pictish appear to have favoured the '-on' ending.

Could the eastern area between the Pennines and the River Trent have been settled by Mercians (specifically the Lindsey Angles) earlier than 590? It is certainly possible that the grey area on the map was part of Elmet despite its different minor ethnicity. This has happened before, for example when the Dumnonii tribal kingdom (Devon and Cornwall) annexed most if not all of Dorchester before losing it gradually to the West Saxons. So an Elmet centred on a southern group of Brigantes could certainly have controlled a Coritani ethnic area. But keep in mind these Coritani had relatives living under the Angles of Lindsey; how hard would they have fought to stay free if the Lindsey Britons were being treated well?

A tidy solution would be that the hero Madoc of Elmet was a lord of this southern area, under the king of Elmet, and that upon his death at Catterick, the Bernicians took over his lands. Unfortunately this is sheer speculation with no supporting evidence whatsoever.

In conclusion, what is fairly clear based on local names, and post-conquest borders, is that the deep pink area is approximately the extent of Elmet in its final years.
