1965

At some point in 1965, the British government was contacted by an alien race dubbed the 456. They demanded a dozen children in exchange for an anti-virus to an influenza outbreak that would otherwise killed millions. Jack Harkness of the Torchwood Institute was ordered to deliver a busload of children from an orphanage in Scotland. One child, Clem McDonald, escaped and ended up on the run, destined to spend the next forty-five years in asylums. With the children delivered, the anti-virus was provided and the flu outbreak was quelled. (TV: Children of Earth: Day One, Children of Earth: Day Four)

The First Doctor's TARDIS materialised in Wimbledon Common, London so Steven Taylor could go on with his own life. He came across Dodo Chaplet, who said she had witnessed a road accident. (TV: The Massacre of St Bartholomew's Eve) Immediately afterwards, the First Doctor, Dodo and Steven travelled to Manhattan, New York City where they met the alien Latter-Day Pantheon. (PROSE: Salvation)

In March, Commodore Charles Waverly was murdered by his wife Lady Catherine Waverly. Group Captain Ian Gilmore was accused of killing him. Less than a week later, Lady Waverly seemingly committed suicide because of the guilt. (AUDIO: Manhunt)

On 26 June, Ian Chesterton and Barbara Wright arrived back in London aboard the Dalek time machine, which they set to self-destruct soon after. Boarding a bus, they contemplated how they would pick up their previous, "normal" lives again, having arrived two years after joining the First Doctor on his travels. (TV: The Chase) The Doctor gave them an envelope of British notes and coins which included a twenty pence coin from 1982. (PROSE: The Time Travellers)

An alien race designated the 456 came to Earth to offer the human race the anti-virus to a new strain of Spanish influenza which would wipe out millions of lives, in exchange for twelve children, to be harvested for certain chemicals that gave the 456 an equivalent of a high from Earth narcotics. The British government and the Torchwood Institute chose Clement McDonald and eleven others from the Holly Tree Lodge orphanage, believing that that no one would miss them, and so kept the act a secret. After arriving in a secluded location, Captain Jack Harkness drove them to a white light, and guided them from there. (TV: Children of Earth: Day Four) Clem, however, managed to escape. He was chased for several miles until the 456 decided to stop. (TV: Children of Earth: Day One)

On 9 November, the Eleventh Doctor, Amy Pond and Rory Williams visited New York City. (AUDIO: Blackout)

On 25 December, the Doctor's TARDIS materialised in the yard of a police station in Liverpool, its scanner malfunctioning. After some initial fears the polluted atmosphere of the 20th century might harm his companions Steven Taylor and Sara Kingdom, who had grown up in the clean air of the future, and some trouble with the local police, the First Doctor repaired the scanner and the TARDIS departed. (TV: The Daleks' Master Plan)

On 31 December, after leaving the Monk on Tigus, the TARDIS materialised in Trafalgar Square during the New Year's Eve celebrations. (TV: The Daleks' Master Plan)

The Sixth Doctor and Melanie Bush visited Salford, Manchester where they encountered the Wishing Beast for the first time in its personal timeline but the second time in theirs. (AUDIO: The Vanity Box)

The Dreadful Flap opened above Darlington. (PROSE: The Dreadful Flap)

There were major riots in Prague, Harlem in New York City and Detroit. The riot in Prague was caused by a person with psychic powers designed by the Soviet Union to provoke extreme emotions in people. Group Captain Ian Gilmore and Professor Rachel Jensen believed that the same was true of the violence in Harlem and Detroit but had no proof of that. (AUDIO: Peshka)

Mary Cleaver and Emma Waverly died. (AUDIO: Sins of the Fathers)

Simon Cooper and his wife were married. He died only three months later. (AUDIO: The Concrete Cage)

Allison Williams' father died. (AUDIO: The Forgotten Village)

Alternative timeline
In an alternative timeline in which Nazi Germany won World War II as a result of the Seventh Doctor and Ace accidentally leaving laser technology in Colditz Castle in October 1944, Elizabeth Klein travelled back in time to Colditz during that incident using the Doctor's TARDIS. She was assisted in making the TARDIS operational by a fellow scientist named Johann Schmidt, who was in actuality an alternative version of the Eighth Doctor. Schmidt fabricated a "flight log" for the TARDIS to allow Klein to pilot the ship back to any of its recent destinations and manipulated her into travelling to 1944 on the pretext of retrieving the Seventh Doctor so that he could teach her to pilot the TARDIS.

Her lover Major Jonas Faber saw through Schmidt's trickery but was too late as Klein had already decided to disobey his orders and make the trip into the past. She left her lover behind, promising to make him Führer by her efforts. Unfortunately for Klein, her arrival in October 1944 alerted the Seventh Doctor to the impending alteration of history and he and Ace were able to prevent it. Klein was stranded in the proper timeline. Believing her mistake had destroyed the correct version of history, she vowed to get the TARDIS back and restore her world. (AUDIO: Colditz, Klein's Story)
