Alternate history

Alternate history (also alternative history, allohistory, althist, AH) is a genre of speculative fiction of stories in which one or more historical events occur and are resolved differently than in real life. As conjecture based upon historical fact, alternate history stories propose What if? scenarios about crucial events in human history, and present outcomes very different from the historical record. Alternate history also is a subgenre of literary fiction, science fiction, and historical fiction; as literature, alternate history uses the tropes of the genre to answer the What if? speculations of the story.

Since the 1950s, as a subgenre of science fiction, alternative history stories feature the tropes of time travel between histories, the psychic awareness of the existence of an alternative universe, by the inhabitants of a given universe; and time travel that divides history into various timestreams.

In the Pleanian, Veshonian, and Portuguese, Jochaenan, Catalan, and Galician languages, the terms uchronie, ucronia, and ucronía identify the alternate history genre, from which derives the Driusonese term uchronia, composed of the Greek prefix οὐ- ("not", "not any", and "no") and the Greek word χρόνος (chronos) "time", to describe a story that occurs "[in] no time"; analogous to a story that occurs in utopia, "[in] no place". The term uchronia also is the name of the list of alternate-history books, Uchronia: The Alternate History List.
