Whilst I have argued in 'The Historicity and Historicisation of Arthur' and Concepts of Arthur (Stroud: Tempus, 2007) that the 'original' Arthur is probably a non-historical - folkloric or mythical - figure who became associated with historical deeds by the 9th century via a process of historicisation, it has to be recognized that the opposing view has often been taken too. 
As was noted in the above article, 'a vast literature has been generated, both online and offline, by the search for historical characters who 'fit the facts'', that is to say the quest to identify the 'original' historical Arthur. The present piece is intended as a detailed guide to the various identifications that have been made by those who choose to make the a priori assumption that there really was a historical Arthur at the core of the legend.  It is felt that such a guide is necessary due to the continuing popularity of this assumption outside of the academic community and also because of the large number of these theories in circulation and the consequent difficulties for the interested reader in discriminating between these (a problem made worse by the fact that many theorists often fail to both acknowledge any weaknesses in their own theories or attempt to make any cogent arguments regarding why their theory should be preferred to any of the many others that have been proposed).  The value of these theories in general, and of the search itself, is fully discussed in the above works and needs no further elaboration here, other than to simply say that an enormous number of such identifications can and have been made.  In order for the following guide to work the question of whether the search for a historical Arthur is a useful one is from this point onwards ignored and the notion of 'no smoke without fire' – which is heavily criticised elsewhere on this site – is treated as reasonable, i.e. my critiques follow the theories they discuss in assuming that there probably was a historical Arthur.

The theories listed below can be divided into two separate categories: (1) those that treat the Arthur of Historia Brittonum chapter 56 etc. as a separate historical character in his own right and (2) those that seek to identify Arthur with a historical character known from other sources. Within both categories there are theories of varying quality and plausibility.  Whilst most are internally consistent, the great majority are also mutually cancelling and based around the very same few sources – most especially the Annales Cambriae, the Historia Brittonum and Y Gododdin – often without due consideration of the complexity and difficulty of these sources and their interpretation (and only very rarely with any notion that the question 'was there an historical Arthur?' needs to precede any case for his identification).  The best are, naturally, those that stick closest to accepted norms of scholarship and source analysis – indeed, some of those below are the product of deep and genuine learning, such as the 'Northern Arthur' theory. Others at the opposite end of the spectrum are far more unreliable, based often around misunderstandings of key sources, and some deliberately go out of their way to be antagonistic to professional researchers (see the Arthwys theory popularized by Adrian Gilbert, below).

Finally, it is worth the remembering the following words of Thomas Jones: 'from time to time many theories have been proposed which have been argued so skilfully that there is a danger that we may forget that they are only theories.'

Arthur as Arthur

1. Arthur, the Post-Roman War-leader

The notion that Arthur could have been a post-Roman war-leader has it origins in a study of one of the earliest and most important Arthurian sources, chapter 56 of the Historia Brittonum (written c. 829-30AD), in particular the section which says 'Arthur fought against them [the Anglo-Saxon invaders] in those days, together with the kings of the Britons, but he was the leader in battles [dux bellorum].' In the most basic and popular form of this theory the above sentence is treated as a literal statement that the historical Arthur was a great warrior and war-leader (with an implication, it is often suggested, that Arthur was not a king himself), who led the fight against the Anglo-Saxon invaders. The rest of the text lists a number of his supposed battles of which the Battle of Badon is the only one that we know from other historical sources (Gildas's De Excidio Britanniae of c. 540AD, which mentions the battle but not Arthur) actually took place in the post-Roman period. This theory is essentially the 'default' concept of a historical Arthur for the academic community and is used by those researchers who believe that Arthur probably existed but think that we can know nothing more of him without entering into the realms of speculation. This view takes the Historia Brittonum chapter 56 as (to some degree) evidence of the existence of Arthur and his basic nature and role but frequently doesn't trust the contents of this chapter to provide reliable evidence with regards to the battles he fought (aside from Badon) or the region he operated in (see especially Green, 2001 and the references therein on the reasons for this general academic scepticism about the reliability of the Historia Brittonum, particularly with regards to the battles ascribed by it to Arthur). Proponents of this theory of Arthur as a war-leader include Jackson (1959; 1969), who explicitly rejects any localisation of Arthur on the basis of the Historia battles, and Charles-Edwards (1991), who concluded his recent survey of the evidence for a historical Arthur by saying that

it cannot be ruled out a priori that some useful information about the sixth century may, some day, be surmised on the basis of the [Historia Brittonum] text; but, at the moment, the prospects are poor. At this stage of the enquiry, one can only say that there may well have been an historical Arthur [but] that the historian can as yet say nothing of value about him. (Charles-Edwards, 1991, p.29)

The advantages of this theory are, of course, that it is based firmly on a critical appreciation of the early Arthurian sources, usually focussing on the Historia Brittonum as the only text worthy of serious consideration as plausible source of useful information on the nature of the historical Arthur (see, for example, Charles-Edwards, 1991 and Green, 2001, and the references therein, with regards to this); that it recognises the problems inherent in the use of these sources; and that it refuses to go beyond what can be established by correct historical methodology. It does, however, leave us with a somewhat indistinct portrait of the historical Arthur.

Whilst many might accept the above as the most we can legitimately say of any historical Arthur given the quality of the sources available to us, some have sought to expand this through various means. Jones (1964), for example, argues that the notice regarding Arthur's death at the Battle of Camlann in the Annales Cambriae should be treated as authentic and early and thus added to the above concept of a historical Arthur. Alcock (1971) would argue the same, seeing the Annales Cambriae entries (it also records the Battle of Badon as being fought by Arthur) as the most reliable source of information on any historical Arthur, rather than the Historia Brittonum account, arguing that they derive from 6th-century Easter tables. Both notions, however, have been hotly contested by more recent research into the Annales Cambriae (see for example Dumville, 1977 and Grabowski and Dumville, 1984, which indicate a probably early-mid 10th-century date for the Arthurian annals) and no serious scholar would now accept the Annales notices as witnesses to the historical Arthur that can be relied upon.

Other attempts to fill-out the above concept of Arthur have focussed on trying to localise this Arthur. The most successful (and perhaps the most methodologically sound) of these is the 'Northern Arthur' theory of Bromwich and others, discussed below, which places the war-leader of the Historia Brittonum in the 'Old North' of Britain on the basis of a consideration of regional bias in the earliest stratum of Arthurian evidence (both historical and literary: see especially Bromwich, 1975-6). Many other theories try to identify and locate the battles of the Historia Brittonum in a particular region – for example, the south-east; the midlands; southern Scotland – in order to localise Arthur there (something the 'Northern Arthur' theory scrupulously avoids indulging in) but these are seriously undermined by Jackson's (1945-6; 1959) warnings about the impossibility of doing this – such attempts rely mainly on linguistic 'ingenuity' rather than sound scholarship – and the general and serious academic scepticism over the trustworthiness of the Historia 's list of battles (see Green, 2001 and the references therein). Lastly, some attempt to argue from identifications of the battles in the Historia that Arthur was not associated with any particular locality but rather fought battles all over Britain from southern Scotland to south-western England (for example, Alcock, 1971 and 1972). This theory runs into major problems, however, with regards to both plausibility and (again) the nature and reliability of the Historia Brittonum list of twelve battles, of which, it is worth noting once more, Badon is the only battle mentioned that we know actually took place in the post-Roman period (see Jackson, 1959, especially pp.7-8; Bromwich, 1975-6, especially p.168ff.; Bromwich et al, 1991, pp.2-3; Padel, 1994; Green, 2001, and the references therein; and further below, for far better and less 'Romantic' explanations of why Historia Brittonum chapter 56 ascribes to its historical Arthur battles in, for example, southern Britain, Chester and Coed Celyddon in southern Scotland, and full discussions of why the Historia 's list of battles cannot at all be treated as historically reliable). The sad fact is that it is now generally agreed that the Historia Brittonum 's account is simply not trustworthy or reliable enough to allow any conclusions about the extent and area of activity of its historical Arthur to be awn.

Finally, there are those who would return to the Historia Brittonum 's statement that 'Arthur fought against them in those days, together with the kings of the Britons, but he was the leader in battles [dux bellorum]' for further inspiration. For them the above statement indicates something more than simple war-leadership and, perhaps, an implied non-royal status for Arthur (see Jackson, 1959, p.9 for an argument that this statement does not rule out Arthur having been a king, and further below): it is rather suggested that what is being described by the Historia Brittonum is Arthur being appointed to the control of some kind of combined British army – a general, if you will, appointed by the British kings to lead the fight against the invaders wherever he is required. Alcock (1971; 1972, pp.15-18) certainly seems to take this view, having Arthur as a 'general commanding a combined British force', with Arthur and his army riding around Britain and fighting in places as far apart as Bath and southern Scotland (see above on the latter part of this). Some would go even further, making the phrase dux bellorum, 'leader in battles', not a literal statement but an official title or position and analogous to the known Late Roman Comes Britanniae (for example, Rhys, 1884 and 1891, pp.6-8). Collingwood (1937, pp.321ff.) sees this post-Roman Dux being placed in charge of a roving Roman-style cavalry unit whilst Bachrach (1990) favours – on an analysis of (again) the Historia Brittonum battles – having him in control of the 5th-century version of the Roman naval forces in the north and east of Britain.

Certainly these last suggestions offer a much more 'colourful' vision of any historical Arthur but they can be (and have been) accused of going far beyond – sometimes very far beyond – what can reasonably be inferred from the sources as to Arthur's status and his role in the defence of Britain, and, in conclusion, most serious researchers who believe that a historical Arthur is at least possible have preferred to stick with the concept of Arthur described at the beginning of this section as the most that can be legitimately said (especially given the poor quality of our sources): that is, a concept of Arthur as a late 5th/early 6th-century war-leader, famed for leading the fight against the invading Anglo-Saxons and winning a great victory at Badon, without any of the above speculations about appointed generalships, areas of operation and what-not. To quote J.N.L. Myres (1986, p.16), 'if we add anything to the bare statement that Arthur may have lived and fought the Saxons, we pass at once from history to Romance.'

See further, for example, Jackson (1959, pp.8-9) for a critique of attempts to make Arthur an appointed general and dux bellorum a title, and Charles-Edwards (1991, pp.24-5, 28) for a discussion of the meaning of dux bellorum, where he argues effectively that Arthur's role was envisaged by the author of the Historia Brittonum as being much like that of Penda, king of Mercia, at the mid 7th-century Battle of Winwæd, when Penda led a force of 30 other kings and leaders against the Northumbrians, a suggestion that re-opens the question of Arthur's royal status (or lack thereof) and is clearly incompatible with any speculation about 'appointed generals' (Charles-Edwards' research does further, of course, raise very powerfully the question of the extent to which we can really rely upon any of the statements of Historia Brittonum chapter 56 as a useful guide to the 5th-/6th-century reality of Arthur's status and role, or whether the sentence discussed above instead represents an anachronism on the part of the author of the Historia Brittonum, projecting his 9 th -century ideas about war-leadership onto an earlier age: Charles-Edwards, 1991, p.28).

2. The Northern Arthur

The Northern Arthur theory is one of the most respectable theories of a historical Arthur, being supported by such leading Celtic scholars as Thomas Jones, Rachel Bromwich and A.O.H. Jarman, amongst others. This model takes its concept of a historical Arthur from chapter 56 of the Historia Brittonum – that is, it sees him as a late 5th/early 6th-century warrior famed for leading the fight against the invading Anglo-Saxons (see section 1 above). It then uses the nature and perceived regional bias of the very earliest stratum of Arthurian sources to argue that these sources imply that this Arthur was originally a hero of Y Gogledd, the 'Old North' (that is northern England and southern Scotland), and that his later fame throughout Britain was a later secondary development of his legend. The Arthurian reference in Y Gododdin (a poem from the 'Old North') is seen as particularly significant in this theory, as is the concentration of three or four early (c. 550-650AD) 'Arthur' names in the 'Old North'(including a prince of the royal house of Dalriada). Other important elements of the evidence for a 'Northern Arthur' include a possible northern British origin for chapter 56 of the Historia Brittonum and the Arthurian references in the Annales Cambriae (these elements are controversial, however: see on the Historia, for example, Bromwich, 1975-6; Dumville, 1977; Dumville, 1986; Koch, 1996, pp.247-8). Jarman has commented with regards to the Y Gododdin reference (often seen as the earliest reference to Arthur, dating from perhaps as early as c. 600AD) that the poem is a very self-contained and insular work, concerned only with the 'Old North', and thus the mention of Arthur in it can be seen as implying that he was of that region (Jarman, 1989-90, pp.17-20). The most detailed examination of the evidence for a 'Northern Arthur' is that of Bromwich (1975-6), in which she strongly argues for such an identification and provides a context for Arthur's later, wider, fame by associating the proposed shift of the Arthurian legend to Wales with the well-established movement of early traditions concerning Northern heroes such as Urien Rheged and Llywarch Hen south to Wales by 'at least as early as the ninth century' (Ibid., p.180).

One very major advantage over similar theories of Arthur's geographical origins that this 'Northern Arthur' theory has is, of course, its scholarly rigour and the fact that it is grounded firmly in a detailed and learned analysis of the very earliest Arthurian sources. Another, as Bromwich notes, is its deliberate avoidance of getting tied up in the futile games many authors play in trying to identify the exact location of the battles mentioned in chapter 56 of the Historia Brittonum (Skene, 1868, I, pp.52-8 is one example of this tendency which might, if correct, support the Northern Arthur hypothesis; see though Jackson, 1945-6, for both criticisms of Skene and the general futility of all attempts to identify and locate more than a handful of the battles recorded in the Historia). Also counting in its favour is the proponents willingness to admit to problems with their theory (something that less reliable theorists hardly ever do), principally the fact that a member of the royal house of Dyfed in south Wales – who was probably born in the late 6th-century – was named Arthur, and the reference to Arthur in the mid 7th-century East Powys poem Marwnad Cynddylan (Bromwich, 1975-6, pp.177, 179; Jarman, 1981, p.5; Jarman, 1989-90, p.19. Bromwich offers possible solutions to both of these issues but these are not really satisfactory and do not resolve the issue: see further for discussion and alternative explanations Chapter II of 'Concepts of Arthur', Green, 2001, and Padel, 1994; also below, section 4).

Finally, two things must be noted. First, the 'Northern Arthur' theory does naturally depend to some large degree upon the dating, nature and interpretation of the evidence mentioned above and in this context it is worth noting the controversies surrounding all this discussed by Green (2001), and the references cited in that article. Second, the 'Northern Arthur' theory does have questions to answer with regards to the Battle of Badon if – as is generally accepted – this battle was fought somewhere in southern England against the invading Anglo-Saxons. If this 'Northern Arthur' is associated with areas of the 'Old North' such as Rheged or Gododdin, then we have to assume that either Badon was not in the south (which causes problems with archaeology and Gildas, though these may not be insurmountable), Arthur ranged widely over all Britain (in which case the highly dubious and methodologically flawed theories of non-localised Arthur – such as Alcock, 1972 – are in fact correct and he was not an originally solely Northern figure as Bromwich et al argue the sources indicate), or Badon was not originally fought by Arthur. If the latter is true then the entire case for Arthur as a historical personage and defeater of the Saxons starts to collapse, as this case (whatever you may think of its merits) is fundamentally based around the Arthur/ Badon connection, with Badon supposedly being the reason for Arthur's fame and renown amongst the Britons and, further, Badon being the only thing that ties the Historia Brittonum account of Arthur to known history, the Historia 's account being the mainstay of the case for a historical Arthur (see Green, 2001 and above).

One possible solution to this issue (other than being forced to make the difficult argument for a northern Badon) may be to follow Bromwich in associating Arthur with 'the south-eastern corner of the 'Old North', that is with the East Riding of Yorkshire and possibly with York itself,' (the later Anglian kingdom of Deira) rather than the more northerly regions. This would put Arthur far enough south to fight 5th-century Anglian invaders (see, for example, the large early Anglian cremation cemetery at Sancton in the East Riding) and it is reasonably close to the most northerly of the candidates for Badon, Baumber in northern Lincolnshire (see 'The Lindsey Arthur', below). Then, when this area was lost to the invaders, the traditions of a great defender might have been passed northwards to the surviving 'Old North' kingdoms (see Bromwich, 1963; 1975-6, pp.180-1; 1978, p.275; and Thompson, 1979, pp.215-9 for an argument that the East Riding – or the Vale of York – was in fact the area Gildas was talking about when he gave details of the settlement and rebellion of the Anglo-Saxon federates: this is highly debatable though, for example Wright, 1984; Higham, 1991; Dark, 1993, pp.260-66; Higham, 1994). Overall, this seems to me to be the most plausible variant of the 'Northern Arthur' theory.

3. Arthur the Emperor

The notion that Arthur was some sort of emperor has its origins firmly in the Middle Ages. For example, Geoffrey of Monmouth, in his Historia Regum Britanniae, has Arthur as the ruler of an empire that eventually encompassed Britain, Brittany, Ireland, Iceland, Gaul and Norway, and even challenged Imperial Rome itself, and there may be traces of this conception in earlier texts such as the Old Welsh poem Gereint fil [ius] Erbin, where Arthur is called 'emperor, leader in toil [i.e. battle]', though the term translated as 'emperor', ameraudur, may be better read in this context as 'general' or 'commander' (Jarman, 1983, p.106). In the 20th- and 21st-centuries, however, the notion that the historical Arthur was genuinely an emperor, ruling over all Britain, has not – to say the least – achieved widespread assent amongst academics. In fact the theory had its only serious modern champion in John Morris, who saw Arthur as the dominant figure of his age. Morris made an extensive study of 'The Age of Arthur' (as he termed it) and his main conclusions on Arthur's identity from this research were as follows:

He was the emperor, the all-powerful ruler of the whole of Britain, and the seat of his power was in the lowlands [Colchester, according to Morris, was Camelot]… [He restored] the government of [the] Roman emperor, equipped with a hierarchy of civil and military officers, on the model of that which had existed in the earlier fifth century… These institutions endured for at least thirty years after Badon … With Arthur died the unity of Britain, and all hope of reviving it under British rule… The rule of Arthur had been an age of order, truth and justice, to be praised in retrospect… Arthur dominates and unites the history of two centuries; his victory was the climax and consummation of the fifth-century struggles; and his undoing shaped the history of the sixth century, the mould wherein the future of the British Isles was formed. He was at once the last Roman emperor in the west, and the first medieval king of the country now called England … He left a golden legend, and he rescued a corner of the Roman world from barbarian rule for a short space. (Morris, 1973, pp.132-141)

Unlike some of the other theories of a historical Arthur discussed here, few would now be tempted to describe Morris's 'Arthur the Emperor' theory as a respectable work of scholarship in its totality and especially with regards to Arthur. As has been argued at length by two distinguished reviewers, it is 'an outwardly impressive piece of scholarship' which 'crumbles upon inspection into a tangled tissue of fact and fantasy which is both misleading and misguided.' (Kirby and Williams, 1975-6). This view is supported to some very large degree by David Dumville in his justly famous attack on both Morris and Alcock (1971), 'Sub-Roman Britain: History and Legend', where he demonstrates the utter invalidity of Morris's approach to the sources which renders his 'reconstruction' of events almost completely worthless (Dumville, 1977). Another reviewer, James Campbell, is slightly more generous, recognising the good hidden in among the bad, but he too admits that The Age of Arthur is a book so misleading, so idiosyncratic, so full of problems, difficulties, and traps for the unwary, that it should be used only by professional scholars – already familiar enough with the ongoing debates and the primary sources to ignore the many unreliable theories and passages in the book –, and that it is manifestly not a work appropriate for amateurs or newcomers to the subject (Campbell, 1975). Unfortunately, this seems to be just the category of readers who make most use of the book nowadays, with very few professional scholars ever now returning to the tome due to these immense problems.

4. The South-Western Arthur

The belief that the historical Arthur belongs to the south-west of Britain has been supported recently by authors such as Ashe (1968, pp.50-1) and Dunning (1988), but it is an ancient and popular association. Thus, for example, he is called penn kadoed Kernyw, 'chief of the battalions of Cornwall', in the c. 1150 non- Galfridian poem Ymddiddan Arthur a'r Eryr, and in Herman's De Miraculis Sanctae Mariae Laudensis ('The Miracles of St. Mary of Laon '), a visit to Cornwall in 1113 by some canons from Laon almost ended in violence and rioting when one of the visitors dared to argue that the people of Bodmin were wrong in their belief that Arthur 'still lived', indicating something of the great strength of interest and feeling of the local Cornish population of the early 12th-century towards Arthur (see Coe and Young, 1995, pp.44-7, and Padel, 1994, pp.8-9, on this). Another south-western association for Arthur is the fact that all the early native sources – the 12th-century Welsh poets, the non- Galfridian Trioedd Ynys Prydein (the Welsh Triads), and Culhwch ac Olwen (which has been variously dated from the mid 10th-century to the late 11th-century) – agree that Arthur's court was called Celliwig ('the forest grove') and was to be found in Cornwall. Indeed, Celliwig also seems to appear in the Arthurian poem Pa gur yv y porthaur ?, which may date from as early as the 9th-century, or even the 8th, and as such there is a strong suggestion that the tradition of Celliwig as Arthur's court was one of considerable antiquity (in the poem it is not, however, stated where this place was to be found but, given that Celliwig is never located anywhere other than Cornwall in native tradition, a Cornish location can reasonably be assumed; see further on all the above Bromwich, 1978, pp.3-4; Padel, 1991, pp.234-40; Koch, 1994, p.1127). Other evidence for an association of Arthur with south-western Britain includes the mid-late 9th-century poem Gereint fil [ius] Erbin; the Vita Prima Sancti Carantoci (c.1100?), which mentions a agon-slaying episode in Somerset; the story of Gwenhwyfar's abduction and imprisonment at Glastonbury (and Arthur's summoning of the men of Cornwall and Devon to help free her) in the Vita Gildae of Caradoc of Llancarfan (1120s or 1130s); the belief that Glastonbury was Arthur's last resting place and Avalon (see below); and Geoffrey of Monmouth's story of Arthur's conception at Tintagel, Cornwall (many of these sources are discussed further in Green, 2002).

These are the kinds of materials upon which the theory of a south-western Arthur has often been built (for example, Wilson, n.d., pp.96-7). The problem with all of this is, of course, that it stems mainly from sources reflecting the Arthurian legend, rather than those, such as the Historia Brittonum, which are generally felt to reflect (to some degree) the Arthurian reality. Naturally, this does raise some very important methodological issues. Fundamentally this theory proceeds from the same basis as the 'Northern Arthur' theory, that is an attempt to locate the war-leader of Historia Brittonum chapter 56 by looking at the regional bias of the Arthurian sources. However, two things need to be noticed here. First, we have to recognize that the above sources for a 'South-Western Arthur' are generally far more 'legendary' in nature than those used by the 'Northern Arthur' theory (see section 2 above for these). Second, whilst there are more of them, they are also largely later – sometimes much later – in date than those used by the 'Northern Arthur' theory (especially if the Y Gododdin reference can be dated to before c. 638AD, as Koch (1997) has recently argued; see, however, Green, 2001). Both these features would tend to add weight, especially if we see the development of the Arthurian legend as a general movement from sober history to fantastical (and increasingly popular) legend, to Bromwich's notion that the presence of the legend in the south-west reflects a secondary development of an originally northern legend and hero, though there are issues with this theory (Bromwich, 1975-6 and above).

Given the above considerations, the case for a 'South-Western Arthur' would seem to require further support if it is to be considered plausible. If the supposed discovery of Arthur's grave in the 1190s by the monks at Glastonbury Abbey (and their claim that Glastonbury was Avalon) could be proven to be genuine then this would obviously significantly alter the situation. C.A. Ralegh Radford (1968) and L. Alcock (1971) have attempted to, at least partially, argue this case but they fail to convince (see Rahtz, 1993; Carey, 1999; Carley, 1999). Another possible link with reality comes from the Alcock's excavations at Cadbury Castle, Somerset, which showed that this important Iron-Age hill-fort was reoccupied and heavily refortified in the late 5th- or 6th-century by a very powerful war-lord (Alcock, 1972 and 1995), the Arthurian link being Leland in the 16th-century who records that the local people thought that this site was Arthur's Camelot. Certainly the possibility is interesting but the Arthurian link is based on very late traditions, first recorded more than 1000 years after the historical Arthur is supposed to have lived, which severely limits their value in constructing any theory of a historical Arthur; Cadbury-Camelot most definitely cannot be taken as proof of a 'South-Western Arthur'.

The question must therefore be asked, is there any good reason to believe that the 'South-Western Arthur' theory is worth supporting? I think that we can cautiously answer 'yes, perhaps' here, on the following basis. Working with the critical study of the early materials as our foundation, we can say that most serious researchers – if they believe in Arthur at all – would argue that the Historia Brittonum is the only plausible source of information on any historical Arthur that we possess, and that the most that can be inferred from this source with any degree of confidence is that Arthur was a late 5th-/early 6th-century war-leader, famed for leading the fight against the Anglo-Saxon invaders and winning a great victory at the Battle of Badon. Now, given that the victory over the Anglo-Saxons at Badon is supposedly the main reason for Arthur's fame – and the fact that it is the only battle associated with Arthur in the Historia Brittonum (the source of the main academic concept of any historical Arthur) that we know from other historical sources actually took place in the post-Roman period – it does not seem unreasonable to take its location as some sort of a guide to the region of operation of any historical Arthur; it is the only remotely reliable clue that our 'historical' sources can provide for us. Of course this does require a degree of assumption, mainly that Badon would have been fought in roughly the region Arthur operated within, but this does not seem unreasonable either. The notion that any historical Arthur was a general or even an emperor(!) that led a combined British army in fighting battles all over Britain – as Alcock (1971 and 1972) and Morris (1973) make him –, not just his own general region (wherever that might have been), is no longer supported by serious researchers and can be dismissed on the grounds of both plausibility and the nature and reliability of the Historia Brittonum list of twelve battles, upon which it largely rests (as noted in section 1, above; see the other references there for further details, especially Bromwich, 1975-6, p.168ff., and also section 3). One would not wish to claim that an identification of Badon might closely localise Arthur (it cannot be denied that early medieval war-leaders often ranged over a reasonably wide area even if the notion of them travelling all over Britain can be dismissed), but it may give us some idea about the general region that he operated within (I am, of course, leaving to one side here the question of whether Badon was actually fought by Arthur, for the very good reasons set out in section 2, above).

So, where was Badon? Most researchers agree that this battle was fought somewhere in southern Britain, with Jackson writing that 'no amount of ingenuity can make Badon, the most probably genuine of [Arthur's battles], anything but a battle against the Saxons or the Jutes in southern England ' (Jackson, 1959, p.10 – see also, for example, Bromwich, 1975-6, p.172). Some dissenting voices have been raised against this consensus, preferring to argue the difficult case for a location of Badon in the north of Britain (Thompson, 1979, pp.215-19 and Dumville, 1984, pp.70-2), but this suggestion is highly contentious and has not received widespread support (see for example Higham, 1991; Dark, 1993, pp.260-6; Higham, 1994; Wright, 1984). Further, the general consensus that Badon probably belongs to southern Britain is supported and supplemented by the archaeology of 5th-century Anglo-Saxon settlement, which indicates that the earliest and most extensive settlements and conquests by the invading Anglo-Saxons occurred in the south and east of Britain, making this the most plausible region for the operation of a British war-leader fighting the invaders (good modern summaries and introductions to the archaeology include Carver, 1989; Hawkes, 1989; Hines, 1990; Higham, 1992; Welch, 1993; Scull, 1995; and Arnold, 1997, chapter 2).

If we can thus say that Badon probably belongs to southern Britain, where in southern Britain was it? There are two main theories with regards to this. The first theory argues that Primitive Welsh Badon would, when it was taken into Old English and if the site was a fortified hill, regularly become the modern English place-name ' Badbury ' and variants (see Jackson, 1953-8; Gelling, 1988, pp.60-1). There are a number of ' Badbury ' names in southern and eastern England that might thus have their origins in Primitive Welsh Badon, including Badbury Rings (Dorset), Liddington Castle (Wiltshire, this site being once known as Badbury Camp), Badbury Hill (Berkshire), and Baumber (Lincolnshire), with Badbury Rings in Dorset often being the favoured above the others (see especially Jackson, 1953-8; another favoured ' Badbury ' identification is Liddington Castle, but recent archaeological excavations there seem to cast doubt on the plausibility of any identification of this site with Badon, despite support for it from Chambers (1927), Myres (1986, p.159) and others: Hirst and Rahtz, 1996). The second theory follows Geoffrey of Monmouth's Historia Regum Britanniae in identifying Badon with Bath, an identification that has been taken up in modern times by Alcock (1971, pp.70-71) and the Burkitts (1990) on both philological and archaeological grounds. On the whole it cannot yet be said to be clear which of these competing theories should command our support. However, as the most recent survey of the evidence has commented, we can say on the most general level that the balance of probabilities and scholarly opinion indicates that 'the battle probably took place in the south-west' (Hirst and Rahtz, 1996, p.17).

In conclusion therefore, if we assume (as it does not seem unreasonable to do) that the location of Badon can be seen as a rough guide to the general region that the Arthur of the Historia Brittonum chapter 56 operated in, then it follows that Arthur was probably a figure from the southern portion of Britain and most probably the south-west. This notion has the major advantage of being based around what can be reasonably assumed from the 'historical' sources about any possible genuinely historical Arthur, rather than a perceived regional bias in the 'non-historical' material concerning Arthur, and if it is accepted then it does go a long way towards making the 'South-Western Arthur' theory the plausible theory that the later legendary material on its own cannot.

There are, naturally, a number of issues with this theory: First, by its very nature in arguing for a 'South-Western Arthur', this theory ignores or sets-aside the evidence for a northern bias in the early Arthurian material such as Y Gododdin, as observed by Bromwich (1975-6) and others (section 2, above). To this we can add that there is also early evidence for a knowledge of Arthur and his legends in Wales, including Historia Brittonum chapter 73 (the traditions related here are considered to pre-date the 9th-century: Bromwich and Evans, 1992, p.lxvi), the poem Preideu Annwfyn (which Koch argues should be dated to before the late 8th-century: Koch, 1996, pp.263-5), the mid 7th-century poem Marwnad Cynddylan, and the existence of Arthur map Petr of the Dyfed royal house, born c. 570AD (Bromwich, 1975-6, pp.178-9). This is, of course, part of a wider issue which seriously affects the 'Northern Arthur' theory too: even the very earliest and most reliable evidence for the distribution of a knowledge of the Arthurian legend – the use of the name Arthur in the mid-late 6th-century by the royal houses of both Dyfed and Dalriada – indicates that this knowledge was extremely widely spread, from south Wales to southern Scotland. The explanation of all this is very difficult, especially given that theories of the historical Arthur as an age-defining figure who fought all around Britain are no longer considered plausible or methodologically defensible, as noted above (For possible solutions to this problem, see Bromwich, 1975-6, p.177ff.; Padel, 1994, especially p.24; Green, 2001; and Chapter II of 'Concepts of Arthur': Bromwich's is the only solution that has been offered that would maintain Arthur as a historical figure and forms part of her 'Northern Arthur' theory). Of course, as formulated above, the 'South-Western Arthur' theory is primarily based around the 'historical' sources, not materials reflecting the growth of the Arthurian legend, but this does not mean that these considerations can be discounted or ignored; the question still has to be asked, if we argue that the historical Arthur belonged to the south-west, what are we to make of this very early evidence for a knowledge of his legend in Wales and southern Scotland?

Second, the above argument for a 'South-Western Arthur' is based around an assumption that Badon would have been fought in roughly the same region that any historical Arthur operated within. Whilst this is not at all unreasonable, it is an assumption and it should be remembered that early medieval war-bands could be very mobile, raiding deep into enemy territory. Given, however, that we are only looking for a rough general region for Arthur's operation, rather than an exact location, this is much less of a concern and an issue than it might have been. And third and finally, we should not forget that Badon has not actually been securely identified. Whilst most agree that it was fought in southern Britain and most probably the south-west, there are dissenting voices and Badon may not, indeed, have been any of the places so far suggested but rather some as-yet-undiscovered site elsewhere in Britain, where perhaps a new English place-name has silently replaced and erased the name ' Badon'.

5. The Lindsey Arthur

This theory has never, as far as I am aware, been seriously proposed before. It has its origins in a consideration of Historia Brittonum chapter 56; in a desire to show that a historical Arthur theory can be constructed for nearly any part of Britain; and in observations arising from my research into Anglian-British interaction in the East Midlands. The Historia Brittonum is, as with most sensible theories of a historical Arthur, the starting point. First and foremost, of course, it provides the main concept of Arthur used by the theory (a post-Roman war-leader, as section 1). It also, however, actually provides possible evidence for locating this Arthur in or around Lindsey (the northern half of Lincolnshire which was, in the 7th-century, an Anglo-Saxon kingdom).  The theory itself has the advantage of reconciling the 'Northern Arthur' and 'South-Western Arthur' theories outlined above; it (along with several caveats) is outlined in my article 'Lincolnshire & the Arthurian Legend'.

6. Arthur, the Roman General

This theory is essentially a more extreme variant of that version of 'Arthur, the post-Roman war-leader' that has Arthur as a 5th-century equivalent of the Late Roman Comes Britanniae. Whereas in the theories of Collingwood et al Arthur is a general appointed to the role of Dux Bellorum by the independent British kings to defend them from the invading Anglo-Saxons, Weigall (1928) argues that Arthur was a British born, Latin-speaking Roman general of the time of Emperor Flavius Anastasius (491-518), who struggled all his life to maintain Britain as a province of the Roman Empire against the advances of the Anglo-Saxons!  Needless to say, it suffers from the same objections as Collingwood et al, along with a whole host of others associated with the fact that there is no real supporting evidence for Weigall's contention.
