King Arthur’s Death by Progeny

Have you ever heard of the famous holy sword of legend, Excalibur? And do you know who wielded such a weapon? Who was the one to pull the sword from the stone? Only he would be deemed worthy of the crown to become Britain’s king. This man was the famous, legendary King Arthur. If you have never heard of Arthur Pendragon, I hope that I can give you a quick gist of his character, particularly the legend of King Arthur and the Battle of Camlann.

King Arthur is the legendary ruler over Britain and was considered a hero by his people. He is famously known for defending Britain from the invasion of the Anglo-Saxons in the sixth century. Early accounts of Arthur describe him as a warrior for Britain and a very successful one at that.1 Mordred, who in Arthur’s legend is Arthur’s son, was deemed a traitor by his own people for rebelling against his own father. This was the prelude to the famous Battle of Camlann.

King Arthur is signified as having strong Celtic values and chivalry. There is debate as to whether Arthur is a historical figure at all, and whether legends credited to him are true, but there is evidence of a famous “Arthur” in history. The earliest mentions of Arthur date back to the seventh century.2 Arthur was described primarily as a king of war, and as time went on, his legendary activity was popularized.3 Arthur is also known for his famous Knights of the Round Table, for his relationship with Sir Lancelot, and for his holy sword, Excalibur. In the Arthurian legend, Arthur’s son Mordred is also his nephew. Arthur conceived Mordred without knowledge of his incest, and this sin furthermore brings him trouble.4

Arthur’s son Mordred was conceived due to Arthur’s incest with his half-sister Morgause. Arthur did not seem to know that Morgause was his half-sister. When Mordred became a young adult, he became one of Arthur’s knights of the Round Table and aspired to be like his father in the sense that he would someday assume the throne. In order to be one of those knights, one had to be recognized as someone with incredible skill, leadership, honor, and chivalry. Mordred eventually got a small taste of what it would be like to take his father’s place. Arthur left the kingdom and his queen, Guinevere, in Mordred’s hands when he departed for Rome. Unfortunately, during this time Mordred decided to betray his father, assume the throne, and marry Guinevere.5 Because of this, Mordred is partly to blame for the downfall of Arthur’s reign and of Camelot.6 Arthur, when he heard of these events, came back to Camelot to take back what was rightfully his. What ensued was… the Battle of Camlann.

The Battle of Camlann is believed to be the historical Battle of Mount Badon, thought to have taken place in the late fifth or early sixth century. This is where Arthur is said to have fought his last battle against the Anglo-Saxons. In the mythos, the Battle of Camlann accounts for the fight between Arthur and his son Mordred. It is believed that because of Mordred’s treason, he himself joined the Anglo-Saxons to fight against his father and take over Camelot. He supposedly promised them land in the instance that they would defeat Arthur, his knights, and his army.7 Arthur pushed Mordred’s forces back, but at the expense of losing some very important knights. Mordred then tried to hide from his father’s wrath. Arthur pursued Mordred to the river Camlann, where both armies inevitably collide. Arthur and Mordred fought to the death, and in the end Arthur thrust a spear straight through Mordred as he lunged at him. With his dying breath, Mordred fatally wounded Arthur, which eventually caused his death as well.

    Huh. I always thought the story of King Arthur was set following the Anglo Saxon Conquest. I would be curious to know if this took place prior to the Christianization of the Celtic Tribes, or after.

    There always is a kernel of truth to legendary figures. It is no doubt that Arthur probably existed as a king of the Britons (Celtic Peoples), but I think most historians agree that the Anglo Saxon invasion of England was largely without bloodshed.

    This article depicts a succinct overview of King Arthur and his downfall at the hands of his nephew and son, Mordred. I found the information very informative and educational because I did not know much regarding Arthurian legends. I never realized that Mordred took over Camelot and forced Guinevere to marry himself when Arthur left for Rome. I also never realized that this was the potential reason behind the fall of Camelot because all of the stories I read said that Camelot fell because of the betrayal of Lancelot and Guinevere. This article was very helpful in providing insight into Arthurian mythos.

  • Michael Thompson

    I didn’t really know about King Arthur, besides the fact that he was the one who drew out the famous sword, Excalibur, and that he ruled Camelot. But I didn’t know he ended up having a son with his half sister, and the son would later kill him. Kind of makes King Arthur less heroic and more a tragic hero, who made dumb mistakes, like sleeping with his half sister, and then leaving the kingdom in the son’s care.

  • Analisa Cervantes

    I knew some of the history involving the King Arthur myths. Mostly about King Arthur’s quest to find Excalibur and the formation of the Knights of the Round Table. I never knew that he had a son/nephew. Or that the two would eventually fight, not as allies but as enemies. And that they would kill the other in cold blood.

  • Todd Brauckmiller

    What a surprising ending, who knew they both ended up killing each other in the end. Now thinking about King Authors story it doesn’t seem all sunshine and rainbows, his own son betrayed him. Why is everyone always killing because of jealousy or greed, no one even cares if there related to you or not they just end up being killed. Very sad story but at least Author was able to defend his kingdom to his last breath, what a shame he ended up being killed by his own son.

  • Hali Garcia

    The legend of King Arthur was always so intriguing to me. Although, I am sorry to say I do not know the whole story. I have always wondered if King Arthur was real and I was confused by some of the different stories on who Mordred was. What struck me about this article was that he had a son with his half sister who ended up betraying him. Overall, this was a great article.

  • Marytrewq

    So, what version are you following exactly? Geoffrey of Monmouth? Because in Geoffrey’s account, Arthur wasn’t killed. He was taken to Avalon to be healed, and eventually came back, according to Merlin. Mordred wasn’t his son either. That was a French propaganda fabrication. Are you combining them both?

  • Mason Kheiv

    The article was incredibly informative. The story of Arthur Pendragon and Mordred is a tragic tale of greed. Mordred wanted the throne for himself and was willing to go to extreme measures to do so. Joining the enemy Anglo-Saxons in order to dethrone his father. The fight ensued and father and son were pitted against each other in mortal combat. Arthur struck a killing blow, but not before being mortally wounded by Mordred. It reminds me of Obi-Wan fighting Anakin Skywalker in Revenge of the Sith.

    When I first started reading this article The first things that came to my mind was the Disney movie The Sword in the Stone and the cartoon’s version of Arthur and Camelot. Though I did know that Arthur was started the knights of the round table and that he had a child with his half-sister I did not know that his son betrayed him and the knights against him.

  • Madison Guerra

    This article was very well written. It gave me information about King Arthur’s rule that i had never previously knew. I never had prior knowledge about King Arthur’s son/nephew and how he ultimately aided in his fathers downfall.
