1881

On 26 October 1881, the Gunfight at the O.K. Corral occurred in Tombstone, Arizona Territory in the USA. The fight, which posed the Earp brothers and Doc Holliday against a group of outlaws, became one of the most iconic events in the history of the Wild West. The First Doctor, Steven Taylor and Dodo Chaplet arrived in Tombstone in the hours before the fight as the Doctor required treatment for his toothache. Holliday did the dentistry. The Doctor, Steven and Dodo subsequently witnessed the gunfight. (TV: The Gunfighters)

While following the Flying Dutchman through time, the Twelfth Doctor materialised on a ship off the coast of Australia. Prince George and Thorpe were on the ship and encountered the Doctor on the deck of the ship as he watched the Dutchman with a telescope. When the Doctor left 1881 in his TARDIS, he took Prince George and Thorpe with him. He returned them to their proper time after they helped the robots that were sailing in the Dutchman.

According to the Seventh Doctor, the last time that he received a haircut was in this year. (AUDIO: The Magic Mousetrap)

Behind the scenes
According to The Brilliant Book 2012, a book that contains non-narrative based information, in Egypt, Madame Vastra helped a group of archaeologists excavate a tomb, with the intention of eating any mummies found inside. Meanwhile, in London, the Eleventh Doctor and Jenny defeated a Kraal plot to replace Prince Bertie with an android duplicate.

One possible "game over" for the video game Don't Blink has the player being sent back in time by a Weeping Angel to the year 1881 to die in a gunfight at the O.K. Corral.
