King Arthur was a legendary British leader who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the late 5th and early 6th centuries. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various sources, including the Annales Cambriae, the Historia Brittonum, and the writings of Gildas. Arthur's name also occurs in early poetic sources such as Y Gododdin.
Arthur is a central figure in the legends making up the Matter of Britain. The legendary Arthur developed as a figure of international interest largely through the popularity of Geoffrey of Monmouth's fanciful and imaginative 12th-century Historia Regum Britanniae (History of the Kings of Britain). In some Welsh and Breton tales and poems that date from before this work, Arthur appears either as a great warrior defending Britain from human and supernatural enemies or as a magical figure of folklore, sometimes associated with the Welsh otherworld Annwn. How much of Geoffrey's Historia (completed in 1138) was adapted from such earlier sources, rather than invented by Geoffrey himself, is unknown.
Although the themes, events and characters of the Arthurian legend varied widely from text to text, and there is no one canonical version, Geoffrey's version of events often served as the starting point for later stories. Geoffrey depicted Arthur as a king of Britain who defeated the Saxons and established a vast empire. Many elements and incidents that are now an integral part of the Arthurian story appear in Geoffrey's Historia, including Arthur's father Uther Pendragon, the magician Merlin, Arthur's wife Guinevere, the sword Excalibur, Arthur's conception at Tintagel, his final battle against Mordred at Camlann, and final rest in Avalon. The 12th-century French writer Chrétien de Troyes, who added Lancelot and the Holy Grail to the story, began the genre of Arthurian romance that became a significant strand of medieval literature. In these French stories, the narrative focus often shifts from King Arthur himself to other characters, such as various Knights of the Round Table.
Arthurian literature thrived during the Middle Ages but waned in the centuries that followed until it experienced a major resurgence in the 19th century. In the 21st century, the legend lives on, not only in literature but also in adaptations for theatre, film, television, comics and other media.
The historical basis for King Arthur has long been debated by scholars. One school of thought, citing entries in the Historia Brittonum (History of the Britons) and Annales Cambriae (Welsh Annals), sees Arthur as a genuine historical figure, a Romano-British leader who fought against the invading Anglo-Saxons some time in the late 5th to early 6th century. The Historia Brittonum, a 9th-century Latin historical compilation attributed in some late manuscripts to a Welsh cleric called Nennius, contains the first datable mention of King Arthur, listing twelve battles that Arthur fought. These culminate in the Battle of Badon, where he is said to have single-handedly killed 960 men. Recent studies, however, question the reliability of the Historia Brittonum.
The other text that seems to support the case for Arthur's historical existence is the 10th-century Annales Cambriae, which also link Arthur with the Battle of Badon. The Annales date this battle to 516-518, and also mention the Battle of Camlann, in which Arthur and Medraut (Mordred) were both killed, dated to 537-539. These details have often been used to bolster confidence in the Historia's account and to confirm that Arthur really did fight at Badon. Problems have been identified, however, with using this source to support the Historia Brittonum's account. The latest research shows that the Annales Cambriae was based on a chronicle begun in the late 8th century in Wales. Additionally, the complex textual history of the Annales Cambriae precludes any certainty that the Arthurian annals were added to it even that early. They were more likely added at some point in the 10th century and may never have existed in any earlier set of annals. The Badon entry probably derived from the Historia Brittonum.
This lack of convincing early evidence is the reason many recent historians exclude Arthur from their accounts of sub-Roman Britain. In the view of historian Thomas Charles-Edwards, "at this stage of the enquiry, one can only say that there may well have been an historical Arthur [but ...] the historian can as yet say nothing of value about him". These modern admissions of ignorance are a relatively recent trend; earlier generations of historians were less sceptical. The historian John Morris made the putative reign of Arthur the organising principle of his history of sub-Roman Britain and Ireland, The Age of Arthur (1973). Even so, he found little to say about a historical Arthur.
Partly in reaction to such theories, another school of thought emerged which argued that Arthur had no historical existence at all. Morris's Age of Arthur prompted the archaeologist Nowell Myres to observe that "no figure on the borderline of history and mythology has wasted more of the historian's time".Gildas' 6th-century polemic De Excidio et Conquestu Britanniae (On the Ruin and Conquest of Britain), written within living memory of Badon, mentions the battle but does not mention Arthur. Arthur is not mentioned in the Anglo-Saxon Chronicle or named in any surviving manuscript written between 400 and 820. He is absent from Bede's early-8th-century Ecclesiastical History of the English People, another major early source for post-Roman history that mentions Badon. The historian David Dumville wrote: "I think we can dispose of him [Arthur] quite briefly. He owes his place in our history books to a 'no smoke without fire' school of thought ... The fact of the matter is that there is no historical evidence about Arthur; we must reject him from our histories and, above all, from the titles of our books."
Some scholars argue that Arthur was originally a fictional hero of folklore--or even a half-forgotten Celtic deity--who became credited with real deeds in the distant past. They cite parallels with figures such as the Kentish Hengist and Horsa, who may be totemic horse-gods that later became historicised. Bede ascribed to these legendary figures a historical role in the 5th-century Anglo-Saxon conquest of eastern Britain. It is not even certain that Arthur was considered a king in the early texts. Neither the Historia nor the Annales calls him "rex": the former calls him instead "dux bellorum" (leader of battles) and "miles" (soldier).
Historical documents for the post-Roman period are scarce, so a definitive answer to the question of Arthur's historical existence is unlikely. Sites and places have been identified as "Arthurian" since the 12th century, but archaeology can confidently reveal names only through inscriptions found in secure contexts. The so-called "Arthur stone", discovered in 1998 among the ruins at Tintagel Castle in Cornwall in securely dated 6th-century contexts, created a brief stir but proved irrelevant. Other inscriptional evidence for Arthur, including the Glastonbury cross, is tainted with the suggestion of forgery.
Several historical figures have been proposed as the basis for Arthur, ranging from Lucius Artorius Castus, a Roman officer who served in Britain in the 2nd or 3rd century, to sub-Roman British rulers such as Riotamus,Ambrosius Aurelianus,Owain Ddantgwyn, and Athrwys ap Meurig. However, no convincing evidence for these identifications has emerged.
The origin of the Welsh name "Arthur" remains a matter of debate. The most widely accepted etymology derives it from the Roman nomen gentile (family name) Artorius. Artorius itself is of obscure and contested etymology, but possibly of Messapian or Etruscan origin. Linguist Stephan Zimmer suggests Artorius possibly had a Celtic origin, being a Latinization of a hypothetical name *Artor?jos, in turn derived from an older patronym *Arto-r?g-ios, meaning "son of the bear/warrior-king". This patronym is unattested, but the root, *arto-r?g, "bear/warrior-king", is the source of the Old Irish personal name Artrí. Some scholars have suggested it is relevant to this debate that the legendary King Arthur's name only appears as Arthur or Arturus in early Latin Arthurian texts, never as Art?rius (though Classical Latin Art?rius became Arturius in some Vulgar Latin dialects). However, this may not say anything about the origin of the name Arthur, as Art?rius would regularly become Art(h)ur when borrowed into Welsh.
Another commonly proposed derivation of Arthur from Welsh arth "bear" + (g)wr "man" (earlier *Arto-uiros in Brittonic) is not accepted by modern scholars for phonological and orthographic reasons. Notably, a Brittonic compound name *Arto-uiros should produce Old Welsh *Artgur (where u represents the short vowel /u/) and Middle/Modern Welsh *Arthwr, rather than Arthur (where u is a long vowel /?:/). In Welsh poetry the name is always spelled Arthur and is exclusively rhymed with words ending in -ur--never words ending in -wr--which confirms that the second element cannot be [g]wr "man".
An alternative theory, which has gained only limited acceptance among professional scholars, derives the name Arthur from Arcturus, the brightest star in the constellation Boötes, near Ursa Major or the Great Bear. Classical Latin Arcturus would also have become Art(h)ur when borrowed into Welsh, and its brightness and position in the sky led people to regard it as the "guardian of the bear" (which is the meaning of the name in Ancient Greek) and the "leader" of the other stars in Boötes.
The familiar literary persona of Arthur began with Geoffrey of Monmouth's pseudo-historical Historia Regum Britanniae (History of the Kings of Britain), written in the 1130s. The textual sources for Arthur are usually divided into those written before Geoffrey's Historia (known as pre-Galfridian texts, from the Latin form of Geoffrey, Galfridus) and those written afterwards, which could not avoid his influence (Galfridian, or post-Galfridian, texts).
The earliest literary references to Arthur come from Welsh and Breton sources. There have been few attempts to define the nature and character of Arthur in the pre-Galfridian tradition as a whole, rather than in a single text or text/story-type. A 2007 academic survey that does attempt this by Caitlin Green identifies three key strands to the portrayal of Arthur in this earliest material. The first is that he was a peerless warrior who functioned as the monster-hunting protector of Britain from all internal and external threats. Some of these are human threats, such as the Saxons he fights in the Historia Brittonum, but the majority are supernatural, including giant cat-monsters, destructive divine boars, dragons, dogheads, giants, and witches. The second is that the pre-Galfridian Arthur was a figure of folklore (particularly topographic or onomastic folklore) and localised magical wonder-tales, the leader of a band of superhuman heroes who live in the wilds of the landscape. The third and final strand is that the early Welsh Arthur had a close connection with the Welsh Otherworld, Annwn. On the one hand, he launches assaults on Otherworldly fortresses in search of treasure and frees their prisoners. On the other, his warband in the earliest sources includes former pagan gods, and his wife and his possessions are clearly Otherworldly in origin.
One of the most famous Welsh poetic references to Arthur comes in the collection of heroic death-songs known as Y Gododdin (The Gododdin), attributed to 6th-century poet Aneirin. One stanza praises the bravery of a warrior who slew 300 enemies, but says that despite this, "he was no Arthur" - that is, his feats cannot compare to the valour of Arthur.Y Gododdin is known only from a 13th-century manuscript, so it is impossible to determine whether this passage is original or a later interpolation, but John Koch's view that the passage dates from a 7th-century or earlier version is regarded as unproven; 9th- or 10th-century dates are often proposed for it. Several poems attributed to Taliesin, a poet said to have lived in the 6th century, also refer to Arthur, although these all probably date from between the 8th and 12th centuries. They include "Kadeir Teyrnon" ("The Chair of the Prince"), which refers to "Arthur the Blessed"; "Preiddeu Annwn" ("The Spoils of Annwn"), which recounts an expedition of Arthur to the Otherworld; and "Marwnat vthyr pen[dragon]" ("The Elegy of Uther Pen[dragon]"), which refers to Arthur's valour and is suggestive of a father-son relationship for Arthur and Uther that pre-dates Geoffrey of Monmouth.
Other early Welsh Arthurian texts include a poem found in the Black Book of Carmarthen, "Pa gur yv y porthaur?" ("What man is the gatekeeper?"). This takes the form of a dialogue between Arthur and the gatekeeper of a fortress he wishes to enter, in which Arthur recounts the names and deeds of himself and his men, notably Cei (Kay) and Bedwyr (Bedivere). The Welsh prose tale Culhwch and Olwen (c. 1100), included in the modern Mabinogion collection, has a much longer list of more than 200 of Arthur's men, though Cei and Bedwyr again take a central place. The story as a whole tells of Arthur helping his kinsman Culhwch win the hand of Olwen, daughter of Ysbaddaden Chief-Giant, by completing a series of apparently impossible tasks, including the hunt for the great semi-divine boar Twrch Trwyth. The 9th-century Historia Brittonum also refers to this tale, with the boar there named Troy(n)t. Finally, Arthur is mentioned numerous times in the Welsh Triads, a collection of short summaries of Welsh tradition and legend which are classified into groups of three linked characters or episodes to assist recall. The later manuscripts of the Triads are partly derivative from Geoffrey of Monmouth and later continental traditions, but the earliest ones show no such influence and are usually agreed to refer to pre-existing Welsh traditions. Even in these, however, Arthur's court has started to embody legendary Britain as a whole, with "Arthur's Court" sometimes substituted for "The Island of Britain" in the formula "Three XXX of the Island of Britain". While it is not clear from the Historia Brittonum and the Annales Cambriae that Arthur was even considered a king, by the time Culhwch and Olwen and the Triads were written he had become Penteyrnedd yr Ynys hon, "Chief of the Lords of this Island", the overlord of Wales, Cornwall and the North.
In addition to these pre-Galfridian Welsh poems and tales, Arthur appears in some other early Latin texts besides the Historia Brittonum and the Annales Cambriae. In particular, Arthur features in a number of well-known vitae ("Lives") of post-Roman saints, none of which are now generally considered to be reliable historical sources (the earliest probably dates from the 11th century). According to the Life of Saint Gildas, written in the early 12th century by Caradoc of Llancarfan, Arthur is said to have killed Gildas' brother Hueil and to have rescued his wife Gwenhwyfar from Glastonbury. In the Life of Saint Cadoc, written around 1100 or a little before by Lifris of Llancarfan, the saint gives protection to a man who killed three of Arthur's soldiers, and Arthur demands a herd of cattle as wergeld for his men. Cadoc delivers them as demanded, but when Arthur takes possession of the animals, they turn into bundles of ferns. Similar incidents are described in the medieval biographies of Carannog, Padarn, and Eufflam, probably written around the 12th century. A less obviously legendary account of Arthur appears in the Legenda Sancti Goeznovii, which is often claimed to date from the early 11th century (although the earliest manuscript of this text dates from the 15th century and the text is now dated to the late 12th to early 13th century). Also important are the references to Arthur in William of Malmesbury's De Gestis Regum Anglorum and Herman's De Miraculis Sanctae Mariae Laudensis, which together provide the first certain evidence for a belief that Arthur was not actually dead and would at some point return, a theme that is often revisited in post-Galfridian folklore.
Geoffrey of Monmouth's Historia Regum Britanniae, completed c. 1138, contains the first narrative account of Arthur's life. This work is an imaginative and fanciful account of British kings from the legendary Trojan exile Brutus to the 7th-century Welsh king Cadwallader. Geoffrey places Arthur in the same post-Roman period as do Historia Brittonum and Annales Cambriae. He incorporates Arthur's father Uther Pendragon, his magician advisor Merlin, and the story of Arthur's conception, in which Uther, disguised as his enemy Gorlois by Merlin's magic, sleeps with Gorlois's wife Igerna (Igraine) at Tintagel, and she conceives Arthur. On Uther's death, the fifteen-year-old Arthur succeeds him as King of Britain and fights a series of battles, similar to those in the Historia Brittonum, culminating in the Battle of Bath. He then defeats the Picts and Scots before creating an Arthurian empire through his conquests of Ireland, Iceland and the Orkney Islands. After twelve years of peace, Arthur sets out to expand his empire once more, taking control of Norway, Denmark and Gaul. Gaul is still held by the Roman Empire when it is conquered, and Arthur's victory leads to a further confrontation with Rome. Arthur and his warriors, including Kaius (Kay), Beduerus (Bedivere) and Gualguanus (Gawain), defeat the Roman emperor Lucius Tiberius in Gaul but, as he prepares to march on Rome, Arthur hears that his nephew Modredus (Mordred)--whom he had left in charge of Britain--has married his wife Guenhuuara (Guinevere) and seized the throne. Arthur returns to Britain and defeats and kills Modredus on the river Camblam in Cornwall, but he is mortally wounded. He hands the crown to his kinsman Constantine and is taken to the isle of Avalon to be healed of his wounds, never to be seen again.
How much of this narrative was Geoffrey's own invention is open to debate. He seems to have made use of the list of Arthur's twelve battles against the Saxons found in the 9th-century Historia Brittonum, along with the battle of Camlann from the Annales Cambriae and the idea that Arthur was still alive. Arthur's status as the king of all Britain seems to be borrowed from pre-Galfridian tradition, being found in Culhwch and Olwen, the Welsh Triads, and the saints' lives. Finally, Geoffrey borrowed many of the names for Arthur's possessions, close family, and companions from the pre-Galfridian Welsh tradition, including Kaius (Cei), Beduerus (Bedwyr), Guenhuuara (Gwenhwyfar), Uther (Uthyr) and perhaps also Caliburnus (Caledfwlch), the latter becoming Excalibur in subsequent Arthurian tales. However, while names, key events, and titles may have been borrowed, Brynley Roberts has argued that "the Arthurian section is Geoffrey's literary creation and it owes nothing to prior narrative." Geoffrey makes the Welsh Medraut into the villainous Modredus, but there is no trace of such a negative character for this figure in Welsh sources until the 16th century. There have been relatively few modern attempts to challenge the notion that the Historia Regum Britanniae is primarily Geoffrey's own work, with scholarly opinion often echoing William of Newburgh's late-12th-century comment that Geoffrey "made up" his narrative, perhaps through an "inordinate love of lying".Geoffrey Ashe is one dissenter from this view, believing that Geoffrey's narrative is partially derived from a lost source telling of the deeds of a 5th-century British king named Riotamus, this figure being the original Arthur, although historians and Celticists have been reluctant to follow Ashe in his conclusions.
Whatever his sources may have been, the immense popularity of Geoffrey's Historia Regum Britanniae cannot be denied. Well over 200 manuscript copies of Geoffrey's Latin work are known to have survived, as well as translations into other languages. For example, 60 manuscripts are extant containing the Brut y Brenhinedd, Welsh-language versions of the Historia, the earliest of which were created in the 13th century. The old notion that some of these Welsh versions actually underlie Geoffrey's Historia, advanced by antiquarians such as the 18th-century Lewis Morris, has long since been discounted in academic circles. As a result of this popularity, Geoffrey's Historia Regum Britanniae was enormously influential on the later medieval development of the Arthurian legend. While it was not the only creative force behind Arthurian romance, many of its elements were borrowed and developed (e.g., Merlin and the final fate of Arthur), and it provided the historical framework into which the romancers' tales of magical and wonderful adventures were inserted.
The popularity of Geoffrey's Historia and its other derivative works (such as Wace's Roman de Brut) gave rise to a significant numbers of new Arthurian works in continental Europe during the 12th and 13th centuries, particularly in France. It was not, however, the only Arthurian influence on the developing "Matter of Britain". There is clear evidence that Arthur and Arthurian tales were familiar on the Continent before Geoffrey's work became widely known (see for example, the Modena Archivolt), and "Celtic" names and stories not found in Geoffrey's Historia appear in the Arthurian romances. From the perspective of Arthur, perhaps the most significant effect of this great outpouring of new Arthurian story was on the role of the king himself: much of this 12th-century and later Arthurian literature centres less on Arthur himself than on characters such as Lancelot and Guinevere, Percival, Galahad, Gawain, Ywain, and Tristan and Iseult. Whereas Arthur is very much at the centre of the pre-Galfridian material and Geoffrey's Historia itself, in the romances he is rapidly sidelined. His character also alters significantly. In both the earliest materials and Geoffrey he is a great and ferocious warrior, who laughs as he personally slaughters witches and giants and takes a leading role in all military campaigns, whereas in the continental romances he becomes the roi fainéant, the "do-nothing king", whose "inactivity and acquiescence constituted a central flaw in his otherwise ideal society". Arthur's role in these works is frequently that of a wise, dignified, even-tempered, somewhat bland, and occasionally feeble monarch. So, he simply turns pale and silent when he learns of Lancelot's affair with Guinevere in the Mort Artu, whilst in Yvain, the Knight of the Lion, he is unable to stay awake after a feast and has to retire for a nap. Nonetheless, as Norris J. Lacy has observed, whatever his faults and frailties may be in these Arthurian romances, "his prestige is never--or almost never--compromised by his personal weaknesses ... his authority and glory remain intact."
Arthur and his retinue appear in some of the Lais of Marie de France, but it was the work of another French poet, Chrétien de Troyes, that had the greatest influence with regard to the development of Arthur's character and legend. Chrétien wrote five Arthurian romances between c. 1170 and 1190. Erec and Enide and Cligès are tales of courtly love with Arthur's court as their backdrop, demonstrating the shift away from the heroic world of the Welsh and Galfridian Arthur, while Yvain, the Knight of the Lion, features Yvain and Gawain in a supernatural adventure, with Arthur very much on the sidelines and weakened. However, the most significant for the development of the Arthurian legend are Lancelot, the Knight of the Cart, which introduces Lancelot and his adulterous relationship with Arthur's queen Guinevere, extending and popularising the recurring theme of Arthur as a cuckold, and Perceval, the Story of the Grail, which introduces the Holy Grail and the Fisher King and which again sees Arthur having a much reduced role. Chrétien was thus "instrumental both in the elaboration of the Arthurian legend and in the establishment of the ideal form for the diffusion of that legend", and much of what came after him in terms of the portrayal of Arthur and his world built upon the foundations he had laid. Perceval, although unfinished, was particularly popular: four separate continuations of the poem appeared over the next half century, with the notion of the Grail and its quest being developed by other writers such as Robert de Boron, a fact that helped accelerate the decline of Arthur in continental romance. Similarly, Lancelot and his cuckolding of Arthur with Guinevere became one of the classic motifs of the Arthurian legend, although the Lancelot of the prose Lancelot (c. 1225) and later texts was a combination of Chrétien's character and that of Ulrich von Zatzikhoven's Lanzelet. Chrétien's work even appears to feed back into Welsh Arthurian literature, with the result that the romance Arthur began to replace the heroic, active Arthur in Welsh literary tradition. Particularly significant in this development were the three Welsh Arthurian romances, which are closely similar to those of Chrétien, albeit with some significant differences: Owain, or the Lady of the Fountain is related to Chrétien's Yvain; Geraint and Enid, to Erec and Enide; and Peredur son of Efrawg, to Perceval.
Up to c. 1210, continental Arthurian romance was expressed primarily through poetry; after this date the tales began to be told in prose. The most significant of these 13th-century prose romances was the Vulgate Cycle (also known as the Lancelot-Grail Cycle), a series of five Middle French prose works written in the first half of that century. These works were the Estoire del Saint Grail, the Estoire de Merlin, the Lancelot propre (or Prose Lancelot, which made up half the entire Vulgate Cycle on its own), the Queste del Saint Graal and the Mort Artu, which combine to form the first coherent version of the entire Arthurian legend. The cycle continued the trend towards reducing the role played by Arthur in his own legend, partly through the introduction of the character of Galahad and an expansion of the role of Merlin. It also made Mordred the result of an incestuous relationship between Arthur and his sister Morgause and established the role of Camelot, first mentioned in passing in Chrétien's Lancelot, as Arthur's primary court. This series of texts was quickly followed by the Post-Vulgate Cycle (c. 1230-40), of which the Suite du Merlin is a part, which greatly reduced the importance of Lancelot's affair with Guinevere but continued to sideline Arthur, and to focus more on the Grail quest. As such, Arthur became even more of a relatively minor character in these French prose romances; in the Vulgate itself he only figures significantly in the Estoire de Merlin and the Mort Artu. During this period, Arthur was made one of the Nine Worthies, a group of three pagan, three Jewish and three Christian exemplars of chivalry. The Worthies were first listed in Jacques de Longuyon's Voeux du Paon in 1312, and subsequently became a common subject in literature and art.
The development of the medieval Arthurian cycle and the character of the "Arthur of romance" culminated in Le Morte d'Arthur, Thomas Malory's retelling of the entire legend in a single work in English in the late 15th century. Malory based his book--originally titled The Whole Book of King Arthur and of His Noble Knights of the Round Table--on the various previous romance versions, in particular the Vulgate Cycle, and appears to have aimed at creating a comprehensive and authoritative collection of Arthurian stories. Perhaps as a result of this, and the fact that Le Morte D'Arthur was one of the earliest printed books in England, published by William Caxton in 1485, most later Arthurian works are derivative of Malory's.
The end of the Middle Ages brought with it a waning of interest in King Arthur. Although Malory's English version of the great French romances was popular, there were increasing attacks upon the truthfulness of the historical framework of the Arthurian romances - established since Geoffrey of Monmouth's time - and thus the legitimacy of the whole Matter of Britain. So, for example, the 16th-century humanist scholar Polydore Vergil famously rejected the claim that Arthur was the ruler of a post-Roman empire, found throughout the post-Galfridian medieval "chronicle tradition", to the horror of Welsh and English antiquarians. Social changes associated with the end of the medieval period and the Renaissance also conspired to rob the character of Arthur and his associated legend of some of their power to enthrall audiences, with the result that 1634 saw the last printing of Malory's Le Morte d'Arthur for nearly 200 years. King Arthur and the Arthurian legend were not entirely abandoned, but until the early 19th century the material was taken less seriously and was often used simply as a vehicle for allegories of 17th- and 18th-century politics. Thus Richard Blackmore's epics Prince Arthur (1695) and King Arthur (1697) feature Arthur as an allegory for the struggles of William III against James II. Similarly, the most popular Arthurian tale throughout this period seems to have been that of Tom Thumb, which was told first through chapbooks and later through the political plays of Henry Fielding; although the action is clearly set in Arthurian Britain, the treatment is humorous and Arthur appears as a primarily comedic version of his romance character.John Dryden's masque King Arthur is still performed, largely thanks to Henry Purcell's music, though seldom unabridged.
In the early 19th century, medievalism, Romanticism, and the Gothic Revival reawakened interest in Arthur and the medieval romances. A new code of ethics for 19th-century gentlemen was shaped around the chivalric ideals embodied in the "Arthur of romance". This renewed interest first made itself felt in 1816, when Malory's Le Morte d'Arthur was reprinted for the first time since 1634. Initially, the medieval Arthurian legends were of particular interest to poets, inspiring, for example, William Wordsworth to write "The Egyptian Maid" (1835), an allegory of the Holy Grail. Pre-eminent among these was Alfred Tennyson, whose first Arthurian poem "The Lady of Shalott" was published in 1832. Arthur himself played a minor role in some of these works, following in the medieval romance tradition. Tennyson's Arthurian work reached its peak of popularity with Idylls of the King, however, which reworked the entire narrative of Arthur's life for the Victorian era. It was first published in 1859 and sold 10,000 copies within the first week. In the Idylls, Arthur became a symbol of ideal manhood who ultimately failed, through human weakness, to establish a perfect kingdom on earth. Tennyson's works prompted a large number of imitators, generated considerable public interest in the legends of Arthur and the character himself, and brought Malory's tales to a wider audience. Indeed, the first modernisation of Malory's great compilation of Arthur's tales was published in 1862, shortly after Idylls appeared, and there were six further editions and five competitors before the century ended.
This interest in the "Arthur of romance" and his associated stories continued through the 19th century and into the 20th, and influenced poets such as William Morris and Pre-Raphaelite artists including Edward Burne-Jones. Even the humorous tale of Tom Thumb, which had been the primary manifestation of Arthur's legend in the 18th century, was rewritten after the publication of Idylls. While Tom maintained his small stature and remained a figure of comic relief, his story now included more elements from the medieval Arthurian romances and Arthur is treated more seriously and historically in these new versions. The revived Arthurian romance also proved influential in the United States, with such books as Sidney Lanier's The Boy's King Arthur (1880) reaching wide audiences and providing inspiration for Mark Twain's satire A Connecticut Yankee in King Arthur's Court (1889). Although the 'Arthur of romance' was sometimes central to these new Arthurian works (as he was in Burne-Jones's "The Sleep of Arthur in Avalon", 1881-1898), on other occasions he reverted to his medieval status and is either marginalised or even missing entirely, with Wagner's Arthurian operas providing a notable instance of the latter. Furthermore, the revival of interest in Arthur and the Arthurian tales did not continue unabated. By the end of the 19th century, it was confined mainly to Pre-Raphaelite imitators, and it could not avoid being affected by World War I, which damaged the reputation of chivalry and thus interest in its medieval manifestations and Arthur as chivalric role model. The romance tradition did, however, remain sufficiently powerful to persuade Thomas Hardy, Laurence Binyon and John Masefield to compose Arthurian plays, and T. S. Eliot alludes to the Arthur myth (but not Arthur) in his poem The Waste Land, which mentions the Fisher King.
In the latter half of the 20th century, the influence of the romance tradition of Arthur continued, through novels such as T. H. White's The Once and Future King (1958) and Marion Zimmer Bradley's The Mists of Avalon (1982) in addition to comic strips such as Prince Valiant (from 1937 onward). Tennyson had reworked the romance tales of Arthur to suit and comment upon the issues of his day, and the same is often the case with modern treatments too. Bradley's tale, for example, takes a feminist approach to Arthur and his legend, in contrast to the narratives of Arthur found in medieval materials, and American authors often rework the story of Arthur to be more consistent with values such as equality and democracy. In John Cowper Powys's Porius: A Romance of the Dark Ages (1951), set in Wales in 499, just prior to the Saxon invasion, Arthur, the Emperor of Britain, is only a minor character, whereas Myrddin (Merlin) and Nineue, Tennyson's Vivien, are major figures. Myrddin's disappearance at the end of the novel is "in the tradition of magical hibernation when the king or mage leaves his people for some island or cave to return either at a more propitious or more dangerous time" (see King Arthur's messianic return). Powys's earlier novel, A Glastonbury Romance (1932) is concerned with both the Holy Grail and the legend that Arthur is buried at Glastonbury.
The romance Arthur has become popular in film and theatre as well. T. H. White's novel was adapted into the Lerner and Loewe stage musical Camelot (1960) and Walt Disney's animated film The Sword in the Stone (1963); Camelot, with its focus on the love of Lancelot and Guinevere and the cuckolding of Arthur, was itself made into a film of the same name in 1967. The romance tradition of Arthur is particularly evident and in critically respected films like Robert Bresson's Lancelot du Lac (1974), Éric Rohmer's Perceval le Gallois (1978) and John Boorman's Excalibur (1981); it is also the main source of the material used in the Arthurian spoof Monty Python and the Holy Grail (1975).
Retellings and reimaginings of the romance tradition are not the only important aspect of the modern legend of King Arthur. Attempts to portray Arthur as a genuine historical figure of c. 500, stripping away the "romance", have also emerged. As Taylor and Brewer have noted, this return to the medieval "chronicle tradition" of Geoffrey of Monmouth and the Historia Brittonum is a recent trend which became dominant in Arthurian literature in the years following the outbreak of the Second World War, when Arthur's legendary resistance to Germanic enemies struck a chord in Britain.Clemence Dane's series of radio plays, The Saviours (1942), used a historical Arthur to embody the spirit of heroic resistance against desperate odds, and Robert Sherriff's play The Long Sunset (1955) saw Arthur rallying Romano-British resistance against the Germanic invaders. This trend towards placing Arthur in a historical setting is also apparent in historical and fantasy novels published during this period. In recent years the portrayal of Arthur as a real hero of the 5th century has also made its way into film versions of the Arthurian legend, most notably the TV series' Arthur of the Britons (1972-73) and The Legend of King Arthur (1979), and the feature films King Arthur (2004) and The Last Legion (2007).
Arthur has also been used as a model for modern-day behaviour. In the 1930s, the Order of the Fellowship of the Knights of the Round Table was formed in Britain to promote Christian ideals and Arthurian notions of medieval chivalry. In the United States, hundreds of thousands of boys and girls joined Arthurian youth groups, such as the Knights of King Arthur, in which Arthur and his legends were promoted as wholesome exemplars. However, Arthur's diffusion within modern culture goes beyond such obviously Arthurian endeavours, with Arthurian names being regularly attached to objects, buildings, and places. As Norris J. Lacy has observed, "The popular notion of Arthur appears to be limited, not surprisingly, to a few motifs and names, but there can be no doubt of the extent to which a legend born many centuries ago is profoundly embedded in modern culture at every level."
