51st century

In the 51st century, humanity began to spread into the galaxy and to deal with time travel.

Another Ice Age affected Earth during this time. (TV: The Talons of Weng-Chiang; PROSE: Emotional Chemistry; AUDIO: The Butcher of Brisbane)

Earth began to be abandoned by the rich and powerful as the sun being a red giant collapsed into a white dwarf.. Those left behind were fractured into millions of nation-states ("Alliances") battling through the ether in the Transmat Wars. (COMIC: The Keep) Ionisation was used to combat the glaciers caused by the Ice Age, and sites like Brittanicus Base were established by this time to deal with the glaciers. (TV: The Ice Warriors)

Humanity was more sexually liberal in this century than in previous eras, widely accepting both same-sex relations and inter-species ones. (TV: The Doctor Dances) Human bodies in this period evolved to produce more highly evolved pheromones, which made them more sexually attractive than their ancestors. (TV: Day One, Fragments)

This century was also notable for major advances in robot rights. (AUDIO: One Mile Down)

Among humans, however, discrimination against other species was still rampant. Though humans often thought themselves the saviours of others' worlds, the Tenth Doctor was quick to point out that human colonists destroyed planet after planet, along with all native life, as they exploited new worlds for natural resources. (AUDIO: One Mile Down)

The Church was a faith-based military organisation primarily responsible for interstellar security, protecting human populations, and special covert operations. Regular military ranks were replaced by offices such as Bishop, Cleric and Verger. (TV: The Time of Angels, Flesh and Stone)

The Time Agency operated out of this century, but it was closed again in the same century. (TV: The Talons of Weng-Chiang, The Empty Child, Kiss Kiss, Bang Bang)

Law and order collapsed in this century. Derek O'Dell, a fan of the 20th century comic book Aggrotron!, adopted the identity of Courtmaster Cruel, a character from the comic, to strike fear into the hearts of criminals. (AUDIO: Izzy's Story)

The Supreme Alliance of Eastern State, at the initiative of its Minister of Justice Magnus Greel, experimented with time travel using a method developed by the alien scientist Dr Sa Yy Findecker based on double nexus particles and zygma beam, but this proved to be a dead end. Greel was said to be the first human to travel through time, arriving in China during the 19th century, but became horribly disfigured by it. (TV: The Talons of Weng-Chiang, AUDIO: The Butcher of Brisbane)

World War VI also took place in the early 51st century. The Icelandic Alliance fell and the Supreme Alliance of Eastern States, of which 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 Fourth Doctor witnessed. (TV: The Talons of Weng-Chiang, AUDIO: The Butcher of Brisbane)

Also in the early 51st century, Magnus Greel killed approximately 100,000 people, a deed which earned him the epithet "Butcher of Brisbane". (TV: The Talons of Weng-Chiang) Consequently, the area where the corpses were kept became known as the Brisbane Dead Zone. (AUDIO: The Butcher of Brisbane)

The weapons factories of Villengard were destroyed by the War Doctor and replaced by a banana grove. (TV: The Doctor Dances, COMIC: The Whole Thing's Bananas)

The spaceship SS Madame de Pompadour became disabled. Adrift in the Dagmar Cluster, its Clockwork Droids repaired the ship using whatever they could find, including the crew and used their body parts as substitutes for mechanical components, and attempted to kidnap the original Madame de Pompadour from the 18th century to use her brain as their computer core. This was thwarted by the Tenth Doctor. (TV: The Girl in the Fireplace) Its sister ship, the Marie Antoinette, fell through time to ancient Earth. The Clockwork Droids, controlled by a central droid which grew to become a cyborg, eventually surfaced in Victorian London where they harvested organs until the newly regenerated Twelfth Doctor stopped the Half-Face Man. (TV: Deep Breath)

The Eleventh Doctor and Amy Pond, along with River Song witnessed the crash of the Byzantium, then confronted the last of the Weeping Angels in the Maze of the Dead. (TV: The Time of Angels / Flesh and Stone)

The Tenth Doctor and Donna Noble visited the Library where they faced an infestation by the Vashta Nerada. The Doctor met River Song for the first time in his personal timeline (but not in hers). River retrieved the consciousnesses of some 4,022 humans who were uploaded to the memory banks of the supercomputer, CAL, died, and uploaded to the Library's computer. (TV: Silence in the Library / Forest of the Dead)

The Kollo-Zarnista Mining Corporation owned and run Kollo-Zarnista Mining Facility 27, which extracted diamonds from Saturn's atmosphere using Cancri technology. The hive-mind race Ba-El Cratt waged war against the Cancri and the Human Empire when they discovered they were working together to mine diamonds. Three Ba-El Cratt travelled to Saturn to destroy Kollo-Zantista Mining Facility 27. (PROSE: Diamond Dogs)

Some time during this period, the native Swampies of Delta III and Thawn, the leader of the local methane and protein collection and manufacturing refinery, were at war. Thawn was conspiring with the criminal and gun smuggler Rohm-Dutt to wipe the Swampies out. During this period Kroll appeared in its Fourth Manifestation, killing Thawn and Ranquin, leader of the Swampies. The Doctor was able to reduce Kroll back to his normal size and retrieve the segment of the Key to Time lurking within him. (TV: The Power of Kroll) Around this point, Laura Palmer was worried Rohm-Dutt would attack a shipment of diamonds coming out of Saturn. (PROSE: Diamond Dogs)

Some time in the 51st century, (PROSE: Diamond Dogs) the planets of Androzani Major and Minor of the Sirius system were independent. The exceedingly rare but also utterly toxic substance spectrox was found in the caves of Androzani Minor, and a war had broken over the control of the spectrox trade between Morgus of the Sirius Conglomerate and his former partner Sharaz Jek, who used android soldiers. The conflict was effectively over through the deaths of both Morgus and Jek. (TV: The Caves of Androzani)

At some point in this century the SS Madame de Pompadour was damaged by an Ion storm and the Clockwork Droids tried to fix it but as stoped by The Doctor. And a little time after The Doctor left the ship became sentient and believed it was Madame de Pompadour her self. (TV: The Girl in the Fireplace, WC: Pompadour)
