Alternate history

Alternate history (also referred to as alternative history, allohistory, althist, or simply A.H.) is a <a href="/facts/Subgenre/ow1Po53X">subgenre</a> of <a href="/facts/Speculative_fiction/j9dUbo0d">speculative fiction</a> in which one or more <a href="/facts/Historical_events/bSKgXaCA">historical events</a> have occurred but are resolved differently than in actual history. As conjecture based upon historical fact, alternate history stories propose What if? scenarios about crucial events in <a href="/facts/Human_history/uB3yXt4H">human history</a>, and present outcomes very different from the historical record. Some alternate histories are considered a subgenre of <a href="/facts/Science_fiction/d9hE2Lwt">science fiction</a>, or <a href="/facts/Historical_fiction/fIhoVb6M">historical fiction</a>.
Since the 1950s, as a subgenre of science fiction, some alternative history stories have featured the tropes of <a href="/facts/Time_travel/3rmwahY9">time travel</a> 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 <a href="/facts/Timestream/AyktIbcz">timestreams</a>.
