1901

January

 * 22 - Queen Victoria died on the Isle of Wight. A comment by the Fourth Doctor led Sarah Jane Smith to believe that the queen was one of his companions, though he was more probably referring to Victoria Waterfield. The Doctor, however, was present at Victoria's coronation. (DW: Pyramids of Mars, The Curse of Peladon) Victoria's death marked the end of the iconic Victorian era of Earth's history.
 * Edward VII ascended the throne of Great Britain and Ireland. Sometime during his reign (1901-1910), a Rutan invasion of Earth was averted by the Doctor at the Fang Rock lighthouse. (DW: Horror of Fang Rock)

December

 * 12 - While on an expedition to the ruins of Babylon, time sensitive linguist John Lafayette stumbled across a time path to Babylon, circa 570 B.C. (BNA: Walking to Babylon)

 * The first British submarine was launched (DW: Enlightenment)
 * Jack Harkness, who had been buried alive under Cardiff since 27 AD, was recovered by Alice Guppy and the Torchwood Cardiff team when they received a signal from a transmitter hidden on Jack by John Hart.
