King Arthur was a mythical king in the mythology of Great Britain. He lived in the medieval times, in his famous castle, Camelot. He possessed a sword known as Excalibur, given to him by the Lady of the Lake.
King Arthur is a fabled ruler of Sub-Roman Britain who defended his kingdom from the Anglo-Saxons. He is a popular fictional character in modern literature. He won several battles, and had many homes. However, his favorite home was in Camelot. In one of the most famous tales of King Arthur, he pulls a sword out of a stone, making him King of the Britons.
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), completed c. 1138.[1][2]
