Alternate history

Alternate history (also called "alternative history", "allohistory", "uchronie" (French)) is a subgenre of SF that takes Earth history and changes some aspect of it. Compare with historical fantasy, in which there is an earth-history setting with fantastic elements (e.g., Sorcery and Cecilia, or, The Enchanted Chocolate Pot)

Works of alternative history have been written almost as long as works of history and fantasy. Modern science fiction has added time travel and parallel universe stories to the panoply of "what-if" stories.
