Elizabeth I
Elizabeth I was the Queen of England from 1558 to 1603. She considered the Doctor her arch-nemesis for reasons the Doctor himself did not know when he first met her (from his point of view) in 1599 (but see below). (DW: The Shakespeare Code)
The Doctor had previously seen the Queen attempting to influence William Shakespeare's writing via the Time-Space Visualiser. (DW: The Chase)
- Given that the play under discussion is The Merry Wives of Windsor, which was written at some time between 1597 and 1600, this encounter must have been almost contemporaneous with the Tenth Doctor's meeting with the Queen.
Elizabeth I's court astrologer, John Dee was apparently another identity of Jared Khan, who was still fruitlessly hunting the Doctor at the time. At this point the Queen appeared to be on friendly terms with the Seventh Doctor, possibly not realising that he and the Tenth Doctor were in fact the same person (the reason for the Tenth Doctor's lack of recollection of this acquaintance is unknown). However, the Sixth Doctor met Dee in 1568, and he was not Khan on this occasion. (NA: Birthright, ST: Mortlake)
- Possibly Khan was able to impersonate the real John Dee for a time.
In an alternative timeline, the Doctor met another version of Elizabeth I, Gloriana of an England with its own star fleet. (DWU: A Storm of Angels
