King Leondegrance (sometimes Leodegrance, or some other minor variation) was, in Arthurian legend, the father of Queen Guinevere. His kingdom was located somewhere in the south of England, although some sources place it in France.
Stories of his allegiance to Arthur vary. In one account, when the young King Arthur pulled Excalibur from the stone, Leondegrance was one of the few kings to swear loyalty to the new king; but in other accounts, he opposed him, and Arthur's marriage to Guinevere was an attempt to heal the rift.
In some stories, the Round Table was Leondegrance's dowry to Arthur (according to others, it was made by Merlin for Uther Pendragon.
King Arthur is thought to be a king of fantasy whose stories were passed down through the ages.
King Arthur and Merlin were hunting in the forest and came upon a young knight who challenged Arthur.
King Arthur and Guenevere were married and all the knights assembled around the table and swore to uphold the rules and high ideals of the Round Table.
This appears to echo the story of the False Guinevere of French Romance: an identical half-sister of the Queen fathered on the same night who persuaded Arthur that she was his true wife.
Whatever Guinevere was or was not, she has been a useful tool in the hands of the romancers throughout the centuries and has greatly enhanced the legends of King Arthur.
She was the daughter of King Orrge of the Douglas River.
