For the technical term used in
historiography, see
alternative history.For the academic investigation of 'what-if' questions in history, see
counterfactual history.Alternate history or alternative history is a
subgenre of
speculative fiction (or some would say of
science fiction) that is set in a world in which
history has diverged from history as it is generally known. Alternate history
literature asks the question, "What if history had developed differently?" Most works in this genre are based in real historical events, yet feature social, geopolitical, or industrial circumstances that developed differently than our own. While to some extent all
fiction can be described as "alternate history," the subgenre proper comprises fiction in which a change or
point of divergence occurs in the past that causes human society to develop in a way that is distinct from our own.
