A time of anarchy and chaos (roughly 400-600 AD) when most people were disease-ridden and covered with filth, unless they happened to be kings. The cleanest and most well-known king of this time was King Arthur, the King(-ish) of the Britons who had a round table around which sat his band of noble and chivalrous knights guys with weapons (many of whom proved to be not so noble and chivalrous when left to their own devices). Since most popular culture portrayals of him were written centuries after he lived (featuring fashion and architecture from those eras), many Hollywood Historians choose to lump him in with The High Middle Ages (but hey, when have they ever been sticklers for accuracy?).
