Mordred

Mordred is a figure in the legend of King Arthur. The earliest known mention of a possibly historical Medraut is in the Welsh chronicle Annales Cambriae, wherein he and Arthur are ambiguously associated with the Battle of Camlann in a brief entry for the year 537. Medraut's figure seemed to have been regarded positively in the early Welsh tradition and may have been related to that of Arthur's son. As Modredus, Mordred was depicted as Arthur's traitorous nephew and a legitimate son of King Lot in Geoffrey of Monmouth's pseudo-historical work Historia Regum Britanniae, which then served as the basis for the following evolution of the legend from the 12th century.
