Alternate History Science Fiction
Alternate History is more Speculative Fiction than Science Fiction and is more often focused on the "What If?" question than on the science. Alternate History is a sub-genre that explores what the world would look like if a part of history happened differently.
Alternate History stories take place on a world where history takes a different course. Often, a single event is the trigger for the alternate timeline. Usually these are pivotal moments. These moments are often referred to as points of divergence, meaning creating two histories or replacing a future that once existed. While these reimaginings are sometimes mere conjecture, sometimes they are based on science. There are a few tropes of Science Fiction that have become widely used in Alternate History stories: cross-time travel between alternate histories, splitting of time lines, and an awareness of the existence of other timelines. Some common historical foci: WWI, WWII, American Civil War, Roman Empire, historical figures like Napoleon and Kennedy.

Other Features of Alternate History Science Fiction
- Level of Real Science
Low. Generally, Alternate History stories are not concerned with science and technology, or at least not the specifics. Science and technology may be a key point of difference in the alternate world, but with a few exceptions, science and technology is rarely the focus.
- Level of Grand Ideas/Social Implications
High. Alternate History stories postulate a world that has developed differently than our own, which necessitates a commentary on the alternate world and thus our own. Often social, political, environmental, or industrial implications are explored in great detail.
- Level of Characterization
Variable. There are many ways to tell an Alternate History story. Some are character centered, where the reader follows a specific character through alternate timelines or the story focuses on a character in an alternate timeline, rather than the events. However, characterization may be lost at the expense of plot development and exploration of social implications.
- Level of Plot Complexity
High. A strong plot is necessary to world-building in Alternate History stories because the reader must have a strong understanding of how the timeline has been altered.
- Level of Violence
Variable. The level of violence is really going to depend on the focus of the story and the point in history the changes. However, with various wars and political events serving as points of divergence, violence is not uncommon in Alternate History stories.
Related Science Fiction subgenres
Time Travel. In an Alternate History story time travel is often used as a means to alter a timeline.
Social Science Fiction. A significant component to Alternate History stories is an examination of the consequences to the world the result form the divergence in history. Frequently, this component is used by authors as a means for social commentary or exploration of society.
Speculative Fiction. Alternate History stories are focused around "What if?" questions and speculate different worlds and realities based on this question, which means Alternate History is a branch of the Speculative Fiction genre.
