The Time Meddler is a serial in the British science fiction television series Doctor Who, which was first broadcast in four weekly parts from July 3 to July 24, 1965. The story is set on the eastern coast of England in late summer, 1066, and it introduces the Meddling Monk.
The Doctor, Vicki, and new companion Steven Taylor arrive in Saxon Northumbria on the eve of the Viking and Norman invasions. It is 1066, a pivotal moment in British history, and the hand of a mysterious Monk is at work in the nearby monastery. The Monk is actually a time/space traveller from the same planet as the Doctor, and is attempting historical alterations. The Doctor prevents this and traps the Monk in 1066 by removing a critical component of his TARDIS.
