King Arthur is a legendary British king and a central figure in the legends making up the Matter of Britain, the body of Medieval literature and legends about Great Britain and its legendary kings and heroes.

According to medieval histories and romances, a warrior named Arthur led the defense of Britain against Saxon invaders in the late 5th and early 6th centuries. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various sources.

The legendary Arthur developed as a figure of international interest largely through the popularity of Geoffrey of Monmouth's fanciful and imaginative 12th-century Historia Regum Britanniae (History of the Kings of Britain). Although the themes, events and characters of the Arthurian legend varied widely from text to text, and there is no one canonical version, Geoffrey's version of events often served as the starting point for later stories. Geoffrey depicted Arthur as a king of Britain who defeated the Saxons and established an empire over Britain, Ireland, Iceland, Norway and Gaul. Many elements and incidents that are now an integral part of the Arthurian story first appeared in Geoffrey's Historia.

Arthurian literature thrived during the Middle Ages but waned in the centuries that followed until it experienced a major resurgence in the 19th century. In the 21st century, the legend lives on, not only in literature but also in adaptations for theater, film, television, comics and other media.

King Arthur was away on a campaign against the Saxons when his kingdom in Britannia was visited by a time-displaced John F. Kennedy. While Kennedy was desperate to get back home, he still laid Arthur's queen, Guinevere. Arthur returned just after they'd completed their tryst, but Kennedy was sent back to his own time before Arthur caught them.

In 1467, English explorer Henry Radcliffe discovered a paradise-like inlet on the west coast of Atlantis. He named it Avalon Bay in honour of a mythical island in the Arthurian legends.

King Arthur in Worldwar[]

On being told by Benjamin Berkowitz that the Race had fully expected to confront 12th-century technology in their 20th-century invasion of Earth, Sam Yeager was amused to think of the Race expecting to fight King Arthur and Richard the Lion-Hearted, despite the fact that the Arthurian legends are not set in the 12th century.[1]
