History

History was the perception of time relative to past events, or in the case of time travel, events that hadn't happened yet but were meant to, composing "future history."

Despite being involved in many events and always showing up when trouble happened, the Seventh Doctor claimed that history happened even when he wasn't around, which Kadiatu Lethbridge-Stewart said was accidental. (PROSE: Transit)

The Web of Time, described as the "hitching-post of chronology," was created by Rassilon as a meta-structure imposed on history. (AUDIO: Neverland)

As such, history could be changed via anomalies like the Time Field, (TV: Flesh and Stone) and events could diverge from causal nexuses onto alternate timelines. As time changed both histories could be remembered by the people who experienced them, resulting in the memory of parallel time streams. (TV: The Wedding of River Song, AUDIO: Prisoners of Fate) Individuals who survived the negation of their timeline could also remember their version of history, and would not know the real history. (AUDIO: Colditz) Parallel universes had different histories from each other. (PROSE: The Face of the Enemy)

If something was erased from history, its possibility was still imprinted on the structure of the universe. (PROSE: Falls the Shadow)

After learning from the Fourth Doctor that he was only remembered as a war criminal, Magnus Greel quipped that "it [was] the winning side that [wrote] history". (TV: The Talons of Weng-Chiang)
