Camelot is the most famous fictional castle and court associated with the legendary King Arthur in Britain during the interim between the Roman Empire and the Anglo-Saxon Kingdom. Later romance depicts it as the fantastic capital of Arthur's realm, from which he fought many of the battles and quests that made up his life. It is portrayed as a paradise or utopia, paradoxically in the same literary works that depict it as the site of much arbitrary, senseless violence in the name of "chivalry". Various locations in England and Wales have been proposed for the site of the historical Camelot, if indeed it ever existed.
In romantic views of American history, the moniker "Camelot" has been applied to the presidency of John F. Kennedy, as his truncated term was said to have potential and promise for the future, and the period was symbolic of hope for many in the world.
NOTE: There is a popular fringe theory that Camelot was only a model.
