The Treaty of 1213 is a treaty that was created between King John of England and Pope Innocent III on October 3, 1213. This treaty assigned all the land of England over to the Pope, who as the Vicar of Christ, claimed dominion over the whole world. This treaty essentially made the Vatican the owner of the world while the English Crown became the executive governing body.

Many people still believe that this is a legitimate treaty that is still in existence to this very day. The Pope has a long history of crowning kings and queens in Europe and acting as the Vicar of Christ has been the basis of the Pope's power since the beginning. Even today there is a close connection between the Pope and all the heads of state.
