Mordred, also known as Modred or Modredus, was depicted as Arthur's traitorous nephew and a legitimate son of King Lot.
Description[]
Later variants most often characterised him as Arthur's villainous bastard son, born of an incestuous relationship with his half-sister, the Queen of Orkney named either Anna, Orcades, or Morgause. The accounts presented in the Historia and most other versions include Mordred's death at Camlann, typically in a final duel, during which he manages to mortally wound his slayer, Arthur.
Overview[]
Mordred is usually a brother or half-brother to Gawain; however, his other family relations, as well as his relationships with Arthur's wife Guinevere, vary greatly. In a popular telling originating from the French chivalric romances of the 13th century, and made prominent today through its inclusion in Le Morte d'Arthur, Mordred is knighted by Arthur and joins the fellowship of the Round Table. In this narrative, he eventually becomes the main actor in Arthur's downfall as he helps his half-brother Agravain to expose Guinevere and Lancelot's affair and then takes advantage of the resulting civil war to make himself the high king of Britain.
