Alternate History or AH is a fictional genre that imagines what would happen if history had gone differently. It often begins by changing a single historical event, called the point of divergence or POD, and tracing how this produces big changes in the world, diverging it from Our Timeline (OTL) and creating a new, alternate and parallel world. Other names include alternative history, allohistory and uchronie. Although not generally categorized as such, alternate history can be considered a form of worldbuilding, which is more so true for timelines which explore the cultural and societal aspects of the altered world. On the Constructed Worlds Wiki, alternate history timelines are generally classified as a posteriori constructed worlds, meaning they are constructed worlds based on preexisting conditions and circumstances (alternate histories are based on our real world), as opposed to a priori constructed worlds (constructed worlds based on original worlds independent of our own).

Physicists and philosophers theorized the existence of Alternate Timelines and parallel worlds in the late-20th Century. They suggested that time has "branches" as a result of numerous points of divergence in the past. Some speculate that all these branches occur simultaneously, perhaps in other universes. The changes would represent "alternate histories," differing in varying degrees from our own.

These theories have helped inspire the literary genre. Pioneering works like The Man in the High Castle by Philip K. Dick (1962) and For Want of a Nail by Robert Sobel (1973) led to a boom in AH fiction in the 80s and 90s, led by writers like Harry Turtledove and S.M. Stirling. The 90s and 2000s saw many AH-themed video games. Amazon's 2015 show The Man in the High Castle, based on Dick's novel, brought the genre to an even wider audience. On the Internet, Alternate Timelines began appearing in the mid- to late-1990s, first on newsgroups, then on individual web pages, and then on forums and wikis like this one; we started in 2005. Social media like Reddit and DeviantArt now have thriving AH communities, often focused on visuals, but with extensive bodies of written lore. AH YouTube channels like the Alternate History Hub and The Alternate Historian boast viewerships ranging from the tens of thousands to the millions.

Alternate History has often accompanied stories about time travel. In the Back to the Future movies, time travelers Doc and Marty have to keep going back in time to correct small changes that have had unexpected effects on the timeline. In this scene, Doc nicely explains the concepts of alternate timelines and points of divergence. It's a good explanation; there's a chalkboard.

Some historians have used althistorical thinking to explore how a hypothetical change in the past could have affected the course of events. This is known as counterfactual history. It is different from AH because its purpose is to better understand real history rather than create a fictional world, but otherwise it involves very much the same thought process.

Elements of alternate history[edit source]

In alternate history, an author makes the conscious choice to change something in their past. According to Steven H Silver[1], alternate history requires three things:

  1. The story must have a point of divergence from the history of our world prior to the time at which it was written.
  2. The change alters known history.
  3. The work examines the consequences of that change.

Alternate history is related to, but distinct from, counterfactual history - what some professional historians do when they speculate about "what might have happened if..." as a tool of academic research. Many historians dismiss the value of counterfactuals, but others have come to its defense, such as Scottish historian Niall Ferguson.[2]

A few genres of fiction can be confused with alternate history. Future history and science fiction, which take place in the author's future but may now be in our past, like Arthur C. Clarke's 2001: A Space Odyssey, are not alternate history: the author did not intentionally change the past. Secret history, an explanation of real history using made-up or unknown past events, is also not the same as AH.[3]

Alternate histories do not need to:

  • Be set in the past. (Note that on this wiki, we do require timelines to stop at the writer's present.)
  • Spell out the exact point of divergence.
  • Have just a single point of divergence.
  • Deal with large, world-changing events.
  • Include famous people.
  • Be written in any one particular style.

Sliding scale of plausibility[edit source]

The sliding scale of alternate history plausibility

According to TV Tropes, alternate history timelines can be categorized into five different categories based on a "sliding scale of plausibility". They are as follows:

  • Hard alternate history
  • Hard/soft alternate history
  • Soft alternate history
  • Utterly implausible (wank) alternate history
  • Alien Space Bats/Fantastical alternate history

AH fandoms[edit source]

Online fandom[edit source]

Online, alternate history has grown into a large, flourishing community across numerous sites. On most of these, the line has blurred between fans and creators, as fans showcase their own works and help fellow fans find interesting works and timelines, professionally published or not.

Uchronia: The Alternate History List is an online database that contains thousands of alternate history novels, stories, essays and other written content, in several languages. Twice Uchronia was selected as the SciFi Channel's "Sci Fi Site of the Week."[4][5]

The online community has created a new vocabulary to discuss alternate history. On the Usenet group soc.history.what-if, users invented the term "alien space bats" to criticize implausible alternate histories[6] or to add intentionally nonrealistic elements to timelines.[7] One science fiction reviewer in Strange Horizons called alien space bats "everyone’s favourite SF plot McGuffin."[8] popularized the term wank to describe a timeline where one country does unrealistically well.

Online creators have achieved some impressive things. Althistorical maps and other content can be so believable that they're routinely confused with the real thing.[9] Timelines have inspired their own fandoms and fan art. Entire languages have appeared as part of alternate timelines, such as Brithenig, Wenedyk, and numerous other languages created for Ill Bethisad.
