John of England
King John of England was the king of England between 1199 and 1216. He was a brother of both Richard I of England and Joan of England, Queen of Sicily.
While the real King John was in London taking the Crusader's Oath, a doppleganger of the monarch, later revealed to be the android Kamelion, was being used in a plot by the Master to sabotage Earth history by preventing King John's signing of the Magna Carta, a pivotal step in the development of parliamentary democracy on that planet. This plot was foiled by the intervention of the Doctor. The following year, whilst eluding rebel forces, John sent his baggage train across the square-mouthed estuary on the northwest margin of East Anglia, only to have the Crown Jewels it carried accidentally dropped and sunk in its waters. Tegan Jovanka's foreknowledge of this event was summed up in her assessment of John as "the one who lost something in the Wash." (DW: The King's Demons)
