For the past several months, I’ve been having a lot of fun reading recent alternate histories and historical fantasies (I’ve reviewed a couple in earlier posts). As a result, I’ve been thinking about how alternate history works, and what techniques apply to the sub-genre.
Divergence as the Elephant in the Room
At some point, all of us wonder about the road not taken. In our private lives, we wonder how life would have turned out if we’d gone to college B rather than college A, if we’d gotten (or kept) a particular job, etc. The same “what if” question gives rise to alternate history, where we try to imagine our world as made different. Whether the portrayal is fairly realistic (as in Harry Turtledove’s Timeline 191) or completely fantastical (e.g. Jonathon Stroud’s Bartimaeus trilogy), alternate history gives us the chance to consider what our world would be like in entirely different circumstances. And that’s fun, because it can give us insight into our own world, culture, and history today.
Because alternate history is so centrally concerned with what sets the imagined reality apart from our current reality, how the timeline diverges must be established very early on. Thinking about it, I’ve spotted a kind of spectrum of divergence in alternate history:
On the one hand, we have what I call fulcrum divergences. This method is most commonly found in “realistic” alternate histories, which lack magic, monsters, or really anything that could not exist in the real world. Some event is identified as a fulcrum on which history swings, and when creating the story we have things work out differently.
The best example I can think of for this type of alternate history has to be Harry Turtledove’s How Few Remain. In our real history, a Confederate messenger lost General Lee’s plans for the invasion of the North. The Union found the plans, and General McLellan was able to turn the Confederates back at the Battle of Antietam. Turtledove asks “what if the message never fell into Union hands?” and proceeds to create an excellent series of realistic novels that paint a Confederate victory and map out the consequences through World War II. Such “little differences” need not be so minor, however: Philip K. Dick posited a world where the Axis Powers won WWII in his classic The Man in the High Castle, nor need the resulting world be particularly realistic (consider Scott Westerfeld’s Leviathan series, where Darwin discovers DNA). Even fairly fantastical stories like Clay and Susan Griffith’s Vampire Empire series still rely on that one point where history changed. Universal within these stories is that the world’s history follows the familiar path we should all know up to that one key fulcrum moment when it skews Doc Brown-like into an alternate timeline.
The other end of the spectrum are foundational divergences. Typically used in more fantastical alternate histories, foundational divergence occurs so far back in the story’s timeline that its effects percolate through all aspects of the world. The place names, some of the personalities involved may be familiar to us, but they are already skewed relative to our timeline based on events that happened significantly prior to the events of the story.
In Stroud’s Bartimaeus trilogy, Patricia C. Wrede’s Frontier Magic series, or Michael A. Stackpole’s At the Queen’s Command magic has been known and applied within the world for centuries. There is no “point of divergence” with our known history, because instead the impacts of magic diffuse throughout all aspects of society, history, and cultural development. The key difference between such alternate histories and those relying on fulcrum divergence is that all recorded history has to be different from what is known. In these books, the foundational difference (e.g. the presence of magic) occurred or was discovered so far in antiquity that its consequences have percolated throughout the world. As a result, such books can often be enjoyed as secondary-world fantasies.
Between these two poles lie a variety of techniques that authors can use to establish that divergence. Often, authors use a time traveler from our timeline to introduce the divergence. Once in the past, the time traveler proceeds to change (or – sometimes not) the past as we know it.
Excellent examples of this kind of alternate history include books like Eric Flint’s 1632, Michael Moorcock’s Behold the Man and Mary Gentle’s First History sequence. In many respects, these books are similar to those that use a fulcrum divergence: in this case, the time traveler becomes the fulcrum. However, they differ significantly in that typically the protagonist (the time traveler) is aware of the divergence or its possibility. This changes the dynamic of the story and significantly alters the reader’s relationship with the hero.
On the opposite end of the spectrum, one can have an “alternate history” that completely recasts our known reality, which does not take place in any kind of recognizable version of our history. Here, the events of the book are modeled on actual events in our history, but they are depicted in a completely secondary world.
Turtledove’s World at War series employs this technique, depicting the events of WWII in a completely secondary world. Felix Gilman’s The Half-Made World (see my earlier review) similarly (though less historically) models aspects of his world on the American frontier.
Maintaining Suspension of Disbelief in Alternate Histories
The key to constructing an effective alternate history is to keep the reader locked in what Gardner calls the “dream” of the novel. This task is particularly challenging in alternate histories, where the reader knows they are reading something inimical to their pre-existing knowledge of the world. As a result, readers are likely to quickly pounce on perceived flaws, places where the author’s research or techniques fell short. There are several tools that can be used to maintain the reader’s acceptance of the alternate history.
The perspective that the book is written from, and the narrative voice that is employed, are both essential tools to maintain the reader’s disbelief. This is doubly-so if the book is written in first-person, but even when written in third the speech patterns, word choices, and value systems that our narrator employs contribute to the milieu of the era we are depicting. Recently, I read two alternate histories that execute on this aspect perfectly: Cherie Priest’s Dreadnought and Michael A. Stackpole’s At the Queen’s Command (see my earlier reviews here and here, respectively).
In both books, the narrative voice and the dialog employed by the characters rings (at least to my ear) true to the period when the books are set. The words key characters employ, the value systems inherent in their views, the differences in how different characters speak, in both books the quality of voice and dialog help to lock the reader into the alternate history. In At the Queen’s Command, the dialog is strongly reminiscent of other accounts of the late 18th century. As a result, I am able to believe that while there may be magic, I am still reading a story set in the 18th century I am familiar with. The same applies to Dreadnought, which follows a southern Confederate nurse across the frontier.
Nailing the voice like this is partly a question of the writer’s natural ear, but it is also heavily influenced by research. Reading books written in and written about the time period can help provide the “feel” of that time period. And solid research on word use and etymology can help make sure that the dialog is period-appropriate (as Mary Robinette Kowal pointed out recently, people swore differently even one hundred years ago). Research and extensive reading are the keys to nailing this aspect of an alternate history.
But there is a flip side to this coin: When we write alternate histories (or even historical fantasies) there is an understandable temptation to shoe-horn massive amounts of research into the text. After all, not everyone is as familiar with the time period as the author. But this natural tendency has to be handled very delicately because people who enjoy alternate histories are likely those who enjoy history. As a result, they are likely to already have substantial knowledge about history, and thus overloading them with historical information may weaken their engagement with the story.
In historical fantasy, this is a danger that I recently observed in Jasper Kent’s otherwise excellent Twelve. Kent clearly knows the history of 19th century Russia, however in many places he assumes that his readers do not. For some readers, this is likely not a problem. But for those of us who are familiar with that time period, the extensive expository background that Kent provides detracts from the rising action of the story. Striking a balance between that need for background and the forward motion of the story is key to writing any story based in history. When I think about the authors who do this well, they apply the rule of “less is more” and leave the reader to infer whatever background they do not already know. If we have to pick between momentum and background, I say always go for momentum.
Imagining a Different Today
If futuristic science fiction is about imagining a possible tomorrow, then alternate histories are about imagining a possible present. This at once constrains our world-building (to a greater or lesser degree, we have to conform to known history) while providing the opportunity for very focused imagination. When I read excellent alternate histories, I often think that it is much harder to paint a maserpiece by coloring within the lines. But the best authors of alternate history manage to do exactly that.
