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. 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). Īrthur is a central figure in the legends making up the Matter of Britain. Arthur's name also occurs in early poetic sources such as Y Gododdin. The sparse historical background of Arthur is gleaned from various sources, including the Annales Cambriae, the Historia Brittonum, and the writings of Gildas.

The details of Arthur's story are mainly composed of Welsh and English folklore and literary invention, and modern historians generally agree that he is unhistorical. King Arthur ( Welsh: Brenin Arthur, Cornish: Arthur Gernow, Breton: Roue Arzhur) 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.
