King Arthur is a legendary British leader who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the early 6th century. 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.
There is no firm date available for the birth of King Arthur, as he is considered a legendary figure

The first narrative account of Arthur's life is found in Geoffrey of Monmouth's Latin work Historia Regum Britanniae (History of the Kings of Britain). This work, completed c. 1138, 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 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.
