Historia Brittonum in the context of "Arthurian"

King Arthur (Welsh: Brenin Arthur; Cornish: Arthur Gernow; Breton: Roue Arzhur; French: Roi Arthur) was a legendary king of Britain. He is a folk hero and a central figure in the medieval literary tradition known as the Matter of Britain.

In Welsh sources, Arthur is portrayed as a leader of the post-Roman Britons in battles against the Anglo-Saxons in the late-5th and early-6th centuries. He first appears in two early medieval historical sources, the Annales Cambriae and the Historia Brittonum, but these date to 300 years after he is supposed to have lived, and most historians who study the period do not consider him a historical figure. His name also occurs in early Welsh poetic sources, such as Y Gododdin. The character developed through Welsh mythology, appearing either as a great warrior defending Britain from human and supernatural enemies or as a magical figure of folklore, and was sometimes associated with the Welsh otherworld Annwn.

The following list of legendary kings of Britain (Welsh: brenin y Brythoniaid or brenin Prydain) derives predominantly from Geoffrey of Monmouth's circa 1136 work Historia Regum Britanniae ("the History of the Kings of Britain"). Geoffrey constructed a largely fictional history for the Britons (ancestors of the Welsh, the Cornish and the Bretons), partly based on the work of earlier medieval historians like Gildas, Nennius and Bede, partly from Welsh genealogies and saints' lives, partly from sources now lost and unidentifiable, and partly from his own imagination (see bibliography). Several of his kings are based on genuine historical figures, but appear in unhistorical narratives. A number of Middle Welsh versions of Geoffrey's Historia exist. All post-date Geoffrey's text, but may give us some insight into any native traditions Geoffrey may have drawn on.

Geoffrey's narrative begins with the exiled Trojan prince Brutus, after whom Britain is supposedly named, a tradition previously recorded in less elaborate form in the 9th century Historia Brittonum. Brutus is a descendant of Aeneas, the legendary Trojan ancestor of the founders of Rome, and his story is evidently related to Roman foundation legends.

The historicity of King Arthur has been debated both by academics and popular writers. While there have been many claims that King Arthur was a real historical person, the current consensus among specialists on the period holds him to be a mythological or folkloric figure.

The first definite mention of Arthur appears circa 828 in the Historia Brittonum, where he is presented as a military leader fighting against the invading Saxons in 5th- to 6th-century Sub-Roman Britain at the Battle of Badon, more than three centuries before the work was written. Arthur developed into a legendary figure in the Matter of Britain from the 12th century, following Geoffrey of Monmouth's influential but largely fictional Historia Regum Britanniae.

Welsh mythology, also known as Y Chwedlau (Welsh for 'the legends'), consists of both folk traditions developed in Wales, and traditions developed by the Celtic Britons elsewhere before the end of the first millennium. As in most of the predominantly oral societies Celtic mythology and history were recorded orally by specialists such as druids (Welsh: derwyddon). This oral record has been lost or altered as a result of outside contact and invasion over the years. Much of this altered mythology and history is preserved in mediaeval Welsh manuscripts, which include the Red Book of Hergest, the White Book of Rhydderch, the Book of Aneirin and the Book of Taliesin. Other works connected to Welsh mythology include the ninth-century Latin historical compilation Historia Brittonum (History of the Britons) and Geoffrey of Monmouth's 12th-century Latin chronicle Historia Regum Britanniae (History of the Kings of Britain), as well as later Welsh folklore, such as the materials collected in The Welsh Fairy Book by William Jenkyn Thomas (1908).

Cadwaladr ap Cadwallon (also spelled Cadwalader or Cadwallader in English) was king of Gwynedd in Wales from around 655 to 664 or 682. He died in one of two devastating plagues that happened in 664 and in 682. Little else is known of his reign.

The red dragon (Welsh: y Ddraig Goch), long known as a Welsh symbol, appearing in the Mabinogion, the Historia Brittonum, and the stories of Geoffrey of Monmouth, has, since the accession of Henry VII to the English throne, often been referred to as "The Red Dragon of Cadwaladr". The association with Cadwaladr is a traditional one without any historical basis.

Nennius – or Nemnius or Nemnivus – was a Welsh monk of the 9th century. He has traditionally been attributed with the authorship of the Historia Brittonum, based on the prologue affixed to that work. This attribution is widely considered a secondary (10th-century) tradition.

Nennius was a student of Elvodugus, commonly identified with the bishop Elfodd of Bangor who convinced British ecclesiastics to accept the Continental dating for Easter, and who died in 809 according to the Annales Cambriae.

Brutus, also called Brute of Troy, is a mythical British king. He is described as a descendant of the Trojan hero Aeneas and as the eponymous founder and first king of Britain. This legend first appears in the Historia Brittonum, an anonymous 9th-century historical compilation to which commentary was added by Nennius, but is best known from the account given by the 12th-century chronicler Geoffrey of Monmouth in his Historia Regum Britanniae.

Medieval football is a modern term used for a wide variety of the localised informal football games that were invented and played in England during the Middle Ages. Alternative names include folk football, mob football and Shrovetide football. These games may be regarded as the ancestors of modern codes of football, and by comparison with later forms of football, the medieval matches were chaotic and had few rules.

The Middle Ages saw a rise in popularity of games played annually at Shrovetide (before Lent) throughout England, particularly in London. The games played in England at this time may have arrived with the Roman occupation but there is little evidence to indicate this. Certainly the Romans played ball games, in particular harpastum. There is also one reference to ball games being played in southern Britain prior to the Norman Conquest. In the ninth century Nennius's Historia Brittonum tells that a group of boys were playing at ball (pilae ludus). The origin of this account is either Southern England or Wales. References to a ball game played in northern France known as La Soule or Choule, in which the ball was propelled by hands, feet, and sticks, date from the 12th century.
