Guinevere was the daughter of King Leodegrance. Leodegrance was a loyal knight when Uther Pendragon sat on the throne and he was entrusted with the precious Round Table after Uther's death. He is sometimes referred to as The Keeper of the Table.
When Arthur took the throne, he did not have the support of all the kingdoms and he spent the early part of his reign fighting to prove his worth. Leodegrance was an ally and Arthur came to his aid when Rience attacked -- Rience wanted to control all 12 kingdoms of Britain, Arthur's Kingdom was the 12th. Once Arthur and his men had driven Rience from Leodegrance's kingdom, Leodegrance introduced Arthur to his daughter, Guinevere.
Arthur and Guinevere fall instantly in love and they married. Arthur couldn't be happier - all he needed now was for the rest of the kingdoms to recognise him, as High King and life would be perfect.
Guinevere is abducted by the evil Meleagant. Sir Gawain volunteers to rescue her. But he isn’t the only man intent on rescuing her.
It is Lancelot that finds her. It is Lancelot that saves her. How can she not love this brave and noble knight. If you want to read the rest of this story, you can check it out here.
When Arthur finds out of his wife's unfaithfulness and Lancelot’s disloyalty he accuses both his wife and his knight of High Treason. Guinevere begs Lancelot to leave before he is arrested. On her persistent urging he does. Arthur, in his rage and grief, sentences Guinevere to be burned at the stake as a traitor - what else can he do?
But let us not forget that Arthur is incredibly clever. I like to think that his sentence of Guinevere to death was merely a ploy to trap Lancelot. Arthur knew that Lancelot would find out. He knew that Lancelot would come for her. Arthur sends his most loyal knights to intercept the traitor. Lancelot must die. This treachery cannot be forgiven.
As angry as he is with Lancelot, Sir Gawain cannot bring himself to watch his Queen die, nor can he kill one of his bestfriends. He refuses to attend the execution.
Lancelot does rescue the Queen, but in doing so he kills Gawain's two brothers. Gawain will never forgive Lancelot for this - he wants revenge.
Meanwhile Lancelot takes his lover to safety, but Guinevere is overcome with guilt and, despite everything that has happened, she loves her husband. She returns to Arthur. Lancelot reluctantly lets her go. There is nothing left for him here now, she has made her choice. He goes home to Brittany.
However, Lancelot has to pay for what he had done. Arthur will not let the insult go unpunished. Arthur takes his knights and his army across the water. He leaves Britain and Guinevere in, what he thinks, are the safe hands of Mordred.
But while the cats away the mice will play….Mordred has an evil scheme to take over Arthur’s kingdom and marry his Queen. Guinevere finds out about Mordred's plot and flees, seeking sanctuary first at The Tower of London (because that was built then??? Correct me if I am wrong, but I was under the impression that was built after the Norman occupation) and then at a convent.
Meanwhile, back in Brittany, Gawain, in a fit of rage, kills Lancelot's brothers in battle. He has had his revenge. But it didn’t taste as sweet as he had hoped it would.
News travels from Britain and Arthur learns of Mordred disloyalty. A truce is called. Lancelot tells Arthur that he will travel with him back to Britain and despite what Arthur thinks of him, his loyalty to Camelot has never wavered. Arthur refuses Lancelot’s request. But the battle between the two men is over. Arthur has to return to Camelot.
Guinevere meets Lancelot one more time. They say their farewells and she joins a convent while he joins a monastery.
That is one version of events anyway!
