King Arthur

According to the most widely known version of the legend, Arthur was born from the union of Uther Pendragon and Igraine, Duchess of Cornwall. Uther, besotted with Igraine, enlisted the wizard Merlin to disguise him as Igraine's husband, Duke Gorlois, for one night. In exchange for this service, Merlin demanded the child that would result. Arthur was born and, as arranged, was taken by Merlin to be fostered by Sir Ector, growing up unaware of his royal blood.

Arthur's claim to the throne was established through the Sword in the Stone. After Uther's death left Britain without a clear heir, Merlin caused a sword to appear lodged in an anvil atop a stone in a London churchyard, bearing the inscription that whoever could draw it forth was the rightful king of all Britain. As recounted in Robert de Boron's Merlin (c. 1200) and later Malory's Le Morte d'Arthur (1485), many knights tried and failed, but the young Arthur drew it effortlessly - first merely to provide a sword for his foster brother Sir Kay, and then publicly to prove his claim.

As king, Arthur gathered the greatest knights of the realm at Camelot and established the Round Table, a symbol of equality among his warriors where no seat was superior to another. The Round Table first appears in Wace's Roman de Brut (c. 1155), though it becomes most fully developed in the later prose cycles. Through the Round Table, Arthur created a fellowship dedicated to justice, honour, and the protection of the innocent.

The legends also record Arthur's military achievements. The Historia Brittonum lists twelve battles Arthur fought against the Saxons, culminating in the Battle of Badon Hill, where he reportedly slew 960 men single-handedly. The Annales Cambriae (c. 970) independently confirms Arthur as the victor at Badon. Geoffrey of Monmouth expands these references into a full campaign of conquest, including wars against the Picts, Scots, Norwegians, and even a continental invasion of Gaul.

The end of Arthur's reign is as famous as its beginning. The seeds of destruction were sown through the affair between his queen, Guinevere, and his greatest knight, Lancelot, as told in the French Vulgate Cycle (c. 1215-1235) and Malory. This betrayal fractured the fellowship of the Round Table. Compounding this was the revolt of Mordred - in earlier tradition Arthur's nephew, later his illegitimate son by his half-sister Morgause - who seized the throne while Arthur was campaigning abroad. The two forces met at the Battle of Camlann, where Arthur slew Mordred but sustained mortal wounds himself. He was then borne away to the Isle of Avalon to heal, with the promise that he would return in Britain's hour of greatest need - hence the epithet "the Once and Future King."

The question of a historical Arthur remains one of the most debated topics in medieval scholarship. Candidates proposed by historians include Riothamus, a 5th-century British leader mentioned by the 6th-century historian Jordanes; Ambrosius Aurelianus, a Romano-British war leader praised by Gildas; and Lucius Artorius Castus, a 2nd-century Roman officer stationed in Britain. The name "Arthur" may derive from the Roman family name Artorius, or from the Welsh arth (bear) combined with gwr (man), meaning "bear-man."
