Frequently asked questions

Mordred is the incestuous son of King Arthur and his half-sister, and the traitor who brings about the fall of Camelot. The key point is that he is not a mere external enemy: he is a member of the royal family, which makes his betrayal all the more devastating. In Geoffrey of Monmouth (around 1136), he is at first a usurping nephew; it is only in the Lancelot-Grail cycle (13th century) that his incestuous birth becomes central, making him a cursed figure from the very start.

Anecdotes

In the Arthurian tradition, Mordred is born of incest: King Arthur, unaware of the blood ties between them, lies with his half-sister (Morgause or Anna, depending on the version). This original sin foretells the kingdom's downfall, like a tragic curse hanging over Camelot.

According to legend, Arthur was warned of a prophecy that a child born on the 1st of May would bring about his ruin. He is said to have ordered all the kingdom's newborns gathered into a boat and set adrift at sea. Mordred, the sole survivor of the shipwreck, thus escapes death — an echo of the biblical Massacre of the Innocents.

In the final battle of Camlann, Mordred and Arthur face each other in single combat. Arthur runs his son through with his lance, but Mordred, with a last surge of strength, slides along the shaft to deal his father a mortal wound to the head. The two enemies kill each other.

The character of Mordred evolves over the centuries: in Geoffrey of Monmouth (12th century), he is above all a usurper who seizes the throne and Queen Guinevere in Arthur's absence. Later, in the prose romances such as the Lancelot-Grail, his incestuous birth becomes central and heightens his role as a cursed traitor.

In several versions, Mordred does not merely betray: he marries or tries to marry Guinevere, Arthur's wife, sealing his rebellion. The queen then takes refuge in a tower of London to escape him.

Primary Sources

Geoffrey of Monmouth, Historia Regum Britanniae (around 1136)
Arthur had entrusted the defence of Britain and of Queen Guinevere to his nephew Mordred; but the latter, treacherously, had himself crowned king and took the queen as his wife, in defiance of divine law.
Wace, Roman de Brut (around 1155)
Mordred was the most disloyal of men; he betrayed his uncle and his lord, he loved the queen and took her despite his sworn oath.
La Mort le roi Artu (Lancelot-Grail) (around 1230-1235)
King Arthur struck Mordred so hard that he ran the lance through his body; but Mordred, feeling that he was mortally wounded, struck his father on the helmet with such force that he split the bone of his head.
