51st century

Another Ice Age affects Earth during this time. (DW: The Talons of Weng-Chiang, PDA: Emotional Chemistry). Earth began to be abandoned by the rich and powerful as the sun goes nova. Those left behind have fractured into millions of nation-states battling through the ether in the Transmat Wars. (DWM: The Keep). About the year 5000 the planet is organised into "Alliances"

By this time humanity first started to develop time travel. The Supreme Alliance, at the initiative of its minister of justice Magnus Greel, developed time travel a method based on Double nexus particles and zygma beam, but this proved to be a cull de sac of which nothing good came. Magnus Greel was the first person to travel trough time, but became horribly disfigured for it. (DW: The Talons of Weng-Chiang)
 * nonetheless, the problems with time travel as seen in Talons seem to have been solved by the time the time agency was established.

The Time Agency operated out of this century. However, it is closed down again in same century, and only two agents were left. (DW: The Talons of Weng-Chiang, The Empty Child, TW: Kiss Kiss, Bang Bang'')

The Doctor called this era a scientific dark age.

Major Events

 * Early 51st century - The Icelandic Alliance fell and the Supreme Alliance, of whom Magnus Greel was Minister of Justice, rose in its stead. The Supreme Alliance committed a number of war crimes and was brought down by the Filipino Army at the Battle of Reykjavik, which the Doctor witnessed. (DW: The Talons of Weng-Chiang)


 * unknown - The Time Agency formed and began employing Time Agents for missions in other time periods. (DW: The Empty Child) Later it was closed down and only seven agents were left. (TW: Kiss Kiss, Bang Bang)

Minor Events

 * 5094 - Jack Harkness is voted "rear of the year" (TW: Kiss Kiss, Bang Bang)


 * unknown : The weapons factories of Villengard is destroyed by the Doctor and is replaced by a banana grove (DW:The Doctor Dances)


 * unknown - SS Madame De Pompadour becomes disabled and its computer core begins cannibalizing the crew for parts; when this proves ineffective, it creates clockwork droids and attempts to kidnap the original Madame de Pompadour from the 18th century, a scheme foiled by the Doctor, which results in the ship being left adrift in space. (DW: The Girl in the Fireplace)


 * Unknown - The Doctor and Donna Noble visit The Library where they face an infestation by the Vashta Nerada, and the Doctor meets River Song for the first time in his personal timeline (but not in hers'). The Doctor tells Donna that by this century, despite the availability of other options, humans' love affair with printed paper books continues. The nature of The Library is revealed as the Doctor retrieves the consciousnesses of some 4,022 humans who were uploaded to the memory banks of the supercomputer, CAL, who runs the Library and restores them to life. All but one member of River Song's crew are "killed" by the Vashta Nerada, and Song herself "dies" in the effort to retrieve the 4,022 Library visitors, but the Doctor and CAL arrange for their consciousnesses to survive inside CAL's now-stabilized mainframe. (DW: Silence in the Library, Forest of the Dead)

Notable individuals

 * Jack Harkness, John Hart, Gray and Magnus Greel all came from this century.
 * ''River Song is working in this century, and ultimately ends up preserved in the CAL computer during this time, but given her travels with the Doctor it's uncertain if she was actually a native of the century
