Alternate history

arts Maturity 11-13 Next article →

Alternate history, also known as althist or allohistory, is a subgenre of speculative fiction. It focuses on "what if?" scenarios regarding pivotal moments in human history. Writers use these stories to propose outcomes that differ from the actual historical record.

While often grouped with science fiction or historical fiction, it remains a distinct way of exploring the past. The genre allows creators to speculate on how the course of human events might have been altered. By changing one event, an author can reshape the entire world.

To construct a valid alternate history, a writer must follow three essential conditions. First, there must be a point of divergence. This is a specific moment that splits away from the real historical record. Second, this divergence must cause a change that alters known history. Third, the author must examine the ramifications of that alteration.

These ramifications are the long-term results and consequences of the initial change. This process turns a simple change into a complex, new timeline.

This genre is different from several other types of storytelling. It is not the same as secret history. Secret history documents events that might have happened but had no effect on the recorded outcome. It is also distinct from counterfactual history. Counterfactual history is a form of historiography used to understand real history by exploring an extrapolated timeline.

Some stories are also misidentified as alternate history. For example, science fiction set in the future is not alternate history. To qualify, the story must deal with events that occurred before the time of writing.

Humans have engaged in this type of speculation since antiquity. The earliest examples are found in the works of Livy. In his writings, Livy contemplated a 4th century BC where Alexander the Great survived to attack Europe. He wondered how Rome would have fared in such a war. In the 11th century, Peter Damian explored the concept in his work *De Divina Omnipotentia*. He questioned if God could change the past, such as preventing the founding of Rome.

Later, in 1490, Joanot Martorell wrote *Tirant lo Blanch*. This epic romance imagined a world where the Byzantine Empire was saved from Ottoman conquest.

During the 19th century, the genre grew in popularity and scale. Louis Geoffroy published works imagining Napoleon Bonaparte unifying the world after successful invasions. In 1830, the publication of the Book of Mormon provided what some biographers call an alternative history. This text suggests a different history for the Americas involving a Jewish group from Israel.

In 1845, Nathaniel Hawthorne wrote "P.'s Correspondence," a story where famous dead poets were still alive. The first English novel-length alternate history was *Aristopia* by Castello Holford in 1895. This story depicted a Utopian society built on a gold reef in Virginia.

In the early 20th century, the genre introduced new concepts like time travel. H. G. Wells published *A Modern Utopia* in 1905. He introduced the idea of a person traveling to a geographical equivalent in an alternate world. This became a staple of the genre. In 1931, Sir John Squire published an anthology titled *If It Had Happened Otherwise*. This collection included essays from major scholars and figures like Winston Churchill.

Churchill wrote about a world where the Confederacy won the American Civil War. This sparked further interest in "recursive alternate history," where characters navigate different timelines.

Today, alternate history remains a powerful tool for exploring complex ideas. It connects to broader discussions about politics, sociology, and the nature of time. Writers use it to test social ideas or to provide satire. For instance, James Thurber used it to parody American Civil War stories. By looking at what did not happen, we gain a deeper perspective on the world as it is. It invites us to see history not as a single path, but as a web of possibilities.
