13th century

The 13th century was a time of some interest to the Doctor and his companions. A knight from this century was known to have been brought forward to the late 20th century, thanks to the Master's TOMTIT device. (DW: The Time Monster) During unspecified years this century, the Third Doctor defeated the villainous Lord Waldean de Beauvain, (TVC: The Magician) while the Eleventh Doctor and Amy Pond pursued Shoju, an alien traveller, to Japan. (DWAM: Samurai's Secret) Also, St John's Monastery was built in this century. (DW: The Rebel Flesh)

Likely the most historically significant event, however, happened in 1215, when the Fifth Doctor, Turlough and Tegan thwarted a plan by the Master to undermine King John's promulgation of the Magna Carta. (DW: The King's Demons)
