Magna Carta bears an iconic status in legal history. Signed eight centuries ago by King John at Runnymede, near Windsor, it laid the foundations for constraints on arbitrary power - the basis for the rule of law, democracy, and human rights. The only problem with the historical account is that almost none of it is true. The agreement at Runnymede was not a constitutional document intended to limit power but a peace treaty to preserve the King's rule. Despite many paintings and a commemorative $2 coin showing him holding Magna Carta and a quill, King John never signed it. Oh, and it was not called Magna Carta.
