Magna Carta

Magna Carta was the first document in British history to place legal limits on the powers of the King.

History
In 1215, the nobles of England, chafing under King John's excessive taxation and arbitrary justice, would only renew their oaths of fealty if John agreed to their demands. John was forced to agree, and all parties signed the Magna Carta in June of that year.

As an important document in the history of jurisprudence, and its signing a pivotal moment in human history, the Master sought to prevent its signing, thus altering the course of history, but was prevented from doing so by the Fifth Doctor. (DW: The King's Demons)
