An original copy of the Magna Carta has been discovered in a scrapbook in Kent, England. The tattered document dates back to 1300, 85 years after King John of England was compelled to sign the first agreement limiting the rights of kings. This version was issued by King Edward I (King John's grandson), who was under pressure from the church and the barons to reaffirm good governance, said Sophie Ambler, a research associate with the Magna Carta Project.
