King Arthur
From Monty Python and the Holy Grail to the many remakes of King Arthur, everyone seems to be familiar with the tale of King Arthur. However, historians have questioned the story and agree that many of the facts prove to be unreliable. It seems like the story was based on a Roman military commander named Lucius Artorius Castus. Other historians suggest the tale is inspired by Riothamus, the king of the Britons during the fifth century.
William Shakespeare
There are many people who question William Shakespeare’s legacy and the legitimacy of his work. Researchers believe Shakespeare wrote under a pen name, but some others still question his existence due to a lack of knowledge about his background. A theory uncovered by schoolteacher J. Thomas Looney posits that Shakespeare was actually a man named Edward de Vere. The theory suggests de Vere’s work was published after his death under the name William Shakespeare.
