The Brittonic Age 410 A.D. -- 596 A.D.

A "best estimate" reconstruction

Last Modified: 9th April 2009.

This page differs from "The Ruin and Conquest of Britain 400 A.D. - 600 A.D. As told by the Primary Sources"  in its aim. Rather than being a reconstruction that uses primary sources to the maximum while avoiding contradictions where possible,  this is a more serious attempt at reconstructing the history of Britain in the Brittonic Age. This term (borrowed from C. Snyder) can be used to denote the time from the definite end of Roman Britain in 410 to the establishment of Germanic dominance by c.596. I still use mainly primary sources to tell the history in this page, but they are far fewer in number. That is because I have used only those sources which are reliable for the events they relate.

The scarcity of reliable sources for this period and the lack of constraint this consequently places on historical reconstructions is discussed in The Facts: How much do we really know. This page grapples with this lack of knowledge to come up with a "best estimate" reconstruction, where I have tried to be as unbiassed as possible. The end result is a far less colourful history, but one not greatly different in outline from that in the "Ruin and Conquest". It is less colourful both because many colourful sources are unreliable and because I have deliberately shortened quotes from the sources that remain so as to get across the essential facts only.

I have also made a new map for this page, for the time c.530. It is also a more serious reconstruction, in that it is based largely on the archaeological sites: Germanic cemeteries, and British settlements, which help outline a plausible political situation. Again, this differs from the map for 530 in the Maps Illustrating the Ruin and Conquest of Britain, but not by as much as one might have thought.

Footnotes.

[469] It could be argued that stating "by way of the Ocean" would be unnecessary if Riothamus had come from Britain; it would be the only possible way in that case. Therefore, one could argue, Jordanes is telling us that Riothamus came from Brittany to central Gaul by way of the Atlantic and the Loire, rather than overland as one might have expected. This could have been the safest or quickest way to travel, or it may have been in order to campaign first against the Saxons who infested the Loire at this time. Moreover, there is a Prince of Domnonee (part of Brittany) called Riatham or Riotham who is recorded in the Breton genealogies, and whose floruit could have been around this time. However, the reading that Riothamus was a king who sailed from Britain to the Loire (at some time in the 460s) is at least equally plausible.

[490/501] Gildas' writing here is notoriously obscure. Elsewhere (see 533) he implies that those who witnessed the Saxon revolt (SR) and Ambrosius' victory (AV) had died, and that an ignorant (and immoral) age succeeded them that had "experienced only the calm of the present" following the battle of Badon (BB). He also implies that the morals of his countrymen began to deteriorate more than 10 years before GW. Thus a generation born at most 5 years before BB held most positions of power (and so were probably at least 27 years old) by 10 years before GW. Thus BB was probably at least 32 years before GW. Moreover, the last of the witnesses of the SR must have died (at about age 75 say) at the latest 10 years before GW. That is to say, SR was probably at least 80 years before GW. Now Gildas seems to be saying either that BB was 43 years after AV or (more likely) that it was 43 years before GW. Under the former interpretation, GW would be at least 75 (43+32) years after AV. This is slightly improbable given that elsewhere (see under 458) he implies that, at the time of his writing (GW), it is Ambrosius' grandchildren who are active, presumably as adults (so probably less than 75 years after AV). Under the latter interpretation, SR would be at least 37 (80-43) years before BB, and AV probably at most about 32 (75-43) years before BB. Given that AV was probably no more than 5 years after SR, the relative best estimate chronology for these four events is pretty much set. Their absolute placing is more uncertain.

[550] This is possibly "the Arthur", or at any rate named after "the Arthur" who presumably lived not long before. That "the Arthur" did exist is evidenced by up to five other (somewhat later) instances of the use of the name in the period 550-650. The name thereafter fell into disuse for many centuries. All of these Arthurs are found at the interface of British and Irish cultures. One possible explanation is that "the Arthur" was a leader of Irish mercenaries fighting for the Britons against the Saxons. See Ken Dark, Reading Medieval Studies XXVI, 77-95 (2000). In this context, the hill fort Dinas Powys (perhaps meaning "fort of the pagans") in Glevissig is intriguing, as its unique archaeological remains are perhaps best interpreted as elite Irish warriors (who may well have been pagan in the late 5th century) working for a Brittonic state [2].

Map of Gildasian Britain


 

Discussion of the Map.

Like the maps illustrating the ruin and conquest of Britain, this map descends into speculation in showing precise political boundaries in Britain at the time of Gildas. However, in many of these I have been guided by the work of the respected archaeologist and historian Ken Dark [1,2]. I have also been guided by the distribution of archaeological sites (as shown on the second map below). The result has a few surprises. First, the amount of the Island still under the control of British civitates, centred upon Roman towns, is quite large. In Roman Britain there were probably 17 civitates, forming the "local government" of Britain, as well as a number of tribal or military areas. Of the 17 capitals, 10 were still in British hands until the 2nd half of the 6th century, and 5 were probably still the centres of government of British states. Second, the "Saxon" cultural zone is much larger (at the expense of both the Angles and Jutes) than recorded history (e.g. the Anglo-Saxon chronicle) would suggest. Third, the traditional (according to the Anglo-Saxon chronicle) "West Saxon" heartland north and east of the Isle of White would appear to have been a Jutish area. But then this agrees with what Bede tells us (see 445 above).

The names given to the Brittonic states are those of the corresponding Roman civitates when these are attested by post-Roman inscription, or by Gildas. When Roman names are not so attested, a Brittonic name is used. Some of these (Reged, Gwent, Glevissig) are well-attested in the early Middle Ages, while others (Calchvynydd, Barroc, Ebrauc) are only attested in later documents [3,4]. Reged may be the name by which the civitas of the Carvetii was known. Gwent means the territory of Venta (that is, Venta Silurum, now Caerwent), and seems to have covered the eastern half of the civitas of the Silures. The western half of this came to be known as Glevissig [6], or Glywysing, later Morgannwg, and later still Glamorgan. Calchvynydd, Baroc and Ebrauc may be the successor states to the civitates of the Catuvellauni, Atrebates, and Brigantes respectively. The only Germanic states whose existence prior to the mid 6th century rests upon good evidence are Deira, Sussex, and Kent. These belong to three different Germanic cultural zones, as suggested by the archaeological evidence below. The first is characterized by mainly cremation cemeteries, with some inhumation cemeteries. The second is characterized by a combination of inhumation cemeteries and mixed cemeteries. The third is characterized by an overwhelming preponderance of inhumation cemeteries. On the evidence of Bede (see 445), these can be identified with zones of Anglian, Saxon, and Jutish settlement respectively.

The archaeological evidence (see below) also suggest three major Brittonic cultural zones. The first is the zone in which the evidence of urban and villa occupation is plentiful. Here plentiful means relative to the other areas at the time; the evidence is sparse compared to that in the Roman period, and presumably the level of occupation was similarly reduced. Nevertheless it is plausible [2] that civilian government -- from St. Albans (Verulamium of the Catuvellauni), Silchester (Calleva of the Atebates), Cirencester (Corinium of the Dobunni), Caerwent (Venta of the Silures), and Wroxeter (Viroconium of the Cornovii) -- continued into Gildas' time. Moreover, these areas may have maintained some sort of united government, as in the time of Vortigern (See 440 above), and appointed governors for the rest (or at least the west) of Britain, as Gildas may imply (see 530 above). The second zone is that south of Hadrian's wall. This area is characterized by some evidence of urban survival, and considerable evidence for occupation of Roman forts along Hadrian's wall. On this basis, I have called this an area of military government, but we really have little idea how this area was organized.  The third and final zone is the west (and far north) where there is little evidence of the survival of urban, villa or Roman miltary culture, but plentiful evidence for re-occupation of Iron age forts on hills, promontories and the like. Many of these sites show evidence of a wealthy elite, with imported wine and glassware from the Mediterranean. This, Dark [2] suggests, was a zone of government by kings. I have included the area north of the Trent in this grouping, although there is precious little Brittonic evidence of any kind here.

If this interpretation of the archaeological evidence is correct then we should look for Gildas' five named tyrants among the kingdoms of the west. The kingdoms of two (Constantinus and Vortiporius) are explicitly identified: Dumnonia and Demetia. Maglocunus is well known in Mediaeval Welsh literature as a king of Gwynedd. At the time of Gildas the tribal name Ordovices was probably still in use; the name survives as the Cantref Orddwy in southern Gwynedd. Another tribal region which was eventually taken over by Gwynedd was that of the Deceangli, whose name survives as the Cantref Tegeingl in Eastern Gwynedd. This is probably where Cuneglasus ruled, as Gildas' describes him as driver of the chariot of the Bear's Stronghold. This  translates into welsh as Din Eirth, which is the name of a hill fort in what may well have been Deceangli territory. This leaves Aurelius Caninus. The kingdom of Durotrigia is probably ruled out, as Higham [5] has convincingly argued that this is where Gildas himself lived, and he is unlikely to have got away with this sort of description of his worldly lord. Gildas' order of naming of the kings suggests somewhere in southern or central Wales. According to Dark [1,2], Powys, the kingdom which in Mediaeval times covered central Wales, was the successor to the civitas of the Cornovii, and was thus part of the civilian zone in Gildas' time. Brycheiniog (north of Glevissig) may well still have been part of the kingdom of Demetia at this time. The only kingdom left is that of Glevissig. Thus we can locate Gildas tyrants in the five westernmost kingdoms, as suggested by Dark [2].

Archaeological Map


 

The above map was scanned from the recent book by Dark [2], which shows 5th and 6th century Germanic cemeteries in Britain. Of these I have erased those cemeteries which came into use only in the later 6th century, according to the maps of Morris [3]. Then I have added Roman towns, villas, and forts for which there is archaeological or literary material indicating probable occupation after 490. The data for these sites are taken from the detailed descriptions in the recent book by Snyder [6], occasionally supplemented by Dark [2]. An example of such archaeological evidence is the presence of coins of Emperor Anastasius (491-518), or datable Mediterranean pottery. An example of reliable literary evidence for occupation is that for Luguvalium (Carlisle), which still had a functioning Roman aqueduct and fountain in the late 7th century [7]. These Germanic and Brittonic sites thus should give a picture of Gildas' partitioned Britain (c. 530). As the map shows, Brittonic and Germanic sites do fall into reasonably distinct zones. There are a handful of small Germanic cemeteries in what I have judged to be Brittonic zones, and one Roman town, Lincoln (Lindum colonia), with evidence for continued occupation in what appears to be an Anglian zone.
