Alternate History in Fantasy and Television

Alternate History as a Literary and Television Genre Introduction Alternate history is a genre that explores "what if" scenarios by imagining how the world would be different if a single historical event had turned out differently. These stories diverge from our real timeline at a critical moment—called a point of divergence—and then explore the consequences of that change. Alternate history allows creators to examine how dependent our world is on specific events, people, and choices. The genre appears across multiple media: novels, short stories, television series, and film. Understanding Points of Divergence The key concept in any alternate history is the point of divergence: the moment in history where the fictional timeline splits from our actual past. Everything before this moment remains the same as real history, but from that point forward, events unfold differently. For example, in HBO's The Plot Against America, the divergence occurs in the 1940 U.S. presidential election when Charles Lindbergh wins instead of Franklin D. Roosevelt. This single electoral outcome sets off a cascade of changes: Lindbergh steers the nation toward fascism, the course of World War II potentially changes, and the treatment of Jewish Americans becomes threatened. The story then explores what American society would look like under these altered circumstances. <extrainfo> The specific historical moment chosen for divergence is crucial to the story's effectiveness. A divergence that's too recent or too distant from the story's setting will feel either unconvincing or irrelevant. </extrainfo> Alternate History in Literature Magic Systems as Historical Divergences Some alternate history works introduce fantasy elements by imagining that history took a different technological and intellectual path. Randall Garrett's Lord Darcy series presents a world where a monk systematized magic rather than science centuries ago. In this alternate England, magic functions as their primary explanatory system for how the world works, just as science functions in ours. Interestingly, this means that treatments for disease—like using foxglove for heart conditions—would be understood as magical practices rather than scientific medicine, even though they work just as effectively. This type of divergence is clever because it asks: what if the intellectual foundations of civilization had been completely different? How would that reshape society? Magical Kingdoms as Secret Histories Susanna Clarke's Jonathan Strange & Mr Norrell operates differently. It's set in Napoleonic-era England, but this England has a crucial secret: a separate magical kingdom ruled by the Raven King has existed hidden in Northumbria for over three hundred years. The novel treats this magical kingdom not as fantasy but as overlooked history—a real historical force that shaped England's past in ways conventional historians missed. The insight here is that an alternate history doesn't require a single divergence point; it can instead imagine that something has always been hidden from our historical record. Technological Decline and Mythical Retreat Keith Roberts's Pavane uses a different approach: it imagines that history took a technological step backward. The divergence occurs when the Spanish Armada, backed by successful Spanish intervention, conquers England after assassinating Queen Elizabeth I. The result is a technologically underdeveloped world where steam engines and electricity never became dominant technologies. What makes Pavane interesting is that it also incorporates fairies—"the Old Ones"—as characters whose presence shapes the world. The novel suggests that fairies retreated from the modern world not because they didn't exist, but because industrial civilization made their presence incompatible with human progress. By imagining technological stagnation, the story allows these mythical beings to remain present in human civilization. <extrainfo> Roberts's concept of fairy retreat is interesting philosophically because it suggests a hidden history where magical beings coexisted with humans but gradually disappeared as the world modernized. </extrainfo> Alternate History in Television Political and Military Divergences The most straightforward alternate history shows explore what would happen if major military or political conflicts had ended differently. The Man in the High Castle depicts a world where the Axis Powers won World War II, dividing North America between Japanese and German control. The series explores how utterly different American society would be—politically, socially, and culturally—under totalitarian occupation. SS-GB dramatizes the immediate aftermath of an Axis victory, showing what Britain would look like under Nazi occupation. Rather than exploring a fully-formed alternate society generations later, it focuses on the moment of conquest and the resistance that forms against occupying forces. C.S.A.: The Confederate States of America takes the opposite approach of fictional realism: it presents itself as a British documentary examining what happened in a world where the American Civil War resulted in Confederate victory. By using the documentary format, it creates unsettling verisimilitude—making the horrific alternate history feel disturbingly credible. Time Travel, Parallel Worlds, and Multiple Timelines Some television uses alternate histories differently: instead of imagining a single different past, these shows explore multiple timelines existing simultaneously. Counterpart follows a United Nations agency responsible for monitoring a gateway between two parallel worlds: Alpha and Prime. These worlds split at some point in the past, and now they're engaged in a Cold War-like rivalry. The premise explores espionage and identity when two versions of the same country are in conflict. <extrainfo> Community's "Remedial Chaos Theory" episode uses a simple device—a die roll—to generate six different timeline branches, each showing how different choices by the study group lead to radically different outcomes for the same characters. </extrainfo> The Plot Against America (HBO) creates an alternate history through a failed election: Charles Lindbergh becomes president in 1940, charming the nation toward fascism and complacency about the Holocaust. A journalist works to expose hidden evidence and prevent the spread of American fascism. What makes this alternate history particularly effective is that it starts from a plausible divergence (Lindbergh actually had significant political support in the 1930s) and follows the logical consequences. Science Fiction Meets Alternate History Some television series use science fiction concepts to explore alternate realities, blending the genres. For All Mankind imagines that the Soviet Union landed astronauts on the Moon before the United States, fundamentally altering the space race. Rather than the American victory ending the competition, it intensifies the rivalry. The show explores how this technological competition would reshape American culture, politics, and scientific progress. Doctor Who, which spans decades of television, has featured multiple alternate worlds. The serial Inferno depicts a fascist Great Britain, while later episodes showed cyber-punk versions of Britain. These alternate realities serve as backdrops for exploring how different political systems shape society. Loki and What If…?, both Marvel properties on Disney+, take a different approach. Rather than imagining historical divergences, they explore alternate versions of fictional universes. What If…? presents "what if" scenarios within the Marvel Cinematic Universe—what if specific events in those films had gone differently? Loki involves a Time Variation Authority that polices the timeline, featuring multiple versions of the character from different universes and timelines. <extrainfo> Fringe adds another dimension: a father steals an alternate version of his dead son from another reality, causing damage that fractures the boundaries between worlds and eventually forces the parallel realities to cooperate for survival. </extrainfo> Why Alternate History Matters Alternate history—whether in literature or television—serves several functions for audiences and creators. It allows exploration of counterfactual questions: What would happen if democracy had failed in the 1930s? What if technology had developed differently? How fragile is our current society? By imagining worlds that diverge from ours at specific points, these stories help us understand our actual history better. They suggest that the past wasn't inevitable—that different choices could have produced radically different outcomes. This genre also often functions as social commentary, using fictional divergences to critique real-world political trends or to explore difficult historical "what-ifs" that reveal something true about human nature and society.
