Most novels don't need a prologue. This is the starting point. A prologue is warranted when it delivers something structurally necessary that Chapter One cannot provide in the flow of the main narrative. The clearest case: a different point-of-view character whose perspective frames the main story but who won't appear again. Second case: a mythological, historical, or thematic context that the reader genuinely needs before meeting the protagonist. Third case: a future scene that plants a question whose full significance only lands retroactively. If your prologue is backstory you couldn't fit elsewhere, it's a symptom of a structure problem, not a solution to it.
The dead body prologue – opening on a crime, a death, a crisis – is genre shorthand. It tells readers: this is a thriller; this is a mystery; something like this will happen. It creates a question and makes a promise. Done well, it establishes atmosphere and hooks efficiently. The failure mode is a prologue that is more exciting than the pages that follow. If your prologue opens on a car chase and your first three chapters are in an office building, you've created an expectation problem. The promise of the prologue must be honored by the pacing and content of the main story.
An in medias res prologue opens in the middle of a future event – a moment the story will eventually reach – then steps back to tell the story leading there. It creates momentum and mystery: who are these people, and how did they get here? The technique requires the opening scene to work without the character context that creates normal stakes. The reader has to be hooked by tension alone before they know why it matters. When it works, the reader reads the whole story with the knowledge that it's building toward that prologue moment. When it doesn't, the prologue is just a confusing opening that readers skim.
Agents, editors, and experienced readers often read prologues with skepticism. A prologue is often where writers hide the backstory they couldn't integrate and the world-building they didn't know how to dramatize. An info-dump prologue signals to the industry reader that the writer didn't trust their own Chapter One. A sharp, scene-based prologue that does its structural job signals exactly the opposite. If you're submitting to agents, know that many read Chapter One before the prologue to assess voice and character. Your prologue cannot replace a strong Chapter One – it can only supplement one.
Epic fantasy has a long tradition of prologues that establish the world, the mythology, or the history before the protagonist enters. Done well – Tolkien, Jordan, Le Guin – these prologues create a sense of depth and scale that grounds everything that follows. Done poorly, they front-load the reader with proper nouns, geography, and history they have no emotional investment in yet. The modern reader's tolerance for this kind of prologue has dropped significantly. If you write a world-building prologue, keep it short, keep it tense, and anchor it in a specific scene or voice rather than in dry exposition.
When in doubt, cut the prologue. This is the advice most developmental editors give most of the time, and it's right more often than it's wrong. Take whatever was in your prologue and ask: can this information be delivered in the main narrative through character action and scene? Usually, yes. The backstory can be revealed gradually. The mythology can be shown through how characters interact with their world. The future scene can become the actual climax, not a preview of it. Cutting the prologue and strengthening Chapter One is the revision move that fixes more books than almost any other single change.

Start writing – freeA prologue is warranted when it delivers something essential that Chapter One cannot: a different POV character who won't appear in the main story, a historical or mythological context that frames everything that follows, or a future scene whose significance the reader won't understand until much later. If your prologue is backstory you couldn't fit into Chapter One, it's probably not needed. If removing it would leave the reader unable to understand something crucial, keep it.
The dead body prologue opens with a moment of high stakes – often a death, a crime, or a crisis – before the main narrative begins. It's designed to establish genre tone and create a question the reader wants answered. Used in thrillers and mysteries, it works by making an implicit promise: this story contains what you just saw. The risk is a prologue that's more exciting than the chapters that follow, which creates an expectation problem.
An in medias res prologue drops the reader into the middle of action – often a future scene that the story will eventually reach and contextualize. The reader doesn't yet know who these people are or what led to this moment. The technique creates suspense and forward momentum, but it requires careful execution: the opening scene must be compelling enough to hook the reader without the character context that makes stakes meaningful.
A strong prologue increases commitment by establishing the story's promise early and creating a question the reader wants answered. A weak prologue – especially an info-dump prologue – signals that the writer didn't trust Chapter One to do its job. Many agents and editors skip prologues or skip to Chapter One first. A prologue that confuses, bores, or over-explains reduces the probability a reader will continue. If in doubt, cut it and make Chapter One stronger.
Fantasy and epic fantasy use prologues most – often for world-building context, mythological frame-setting, or a different-era perspective. Thrillers use dead body prologues frequently. Literary fiction rarely uses them. Romance almost never does. Contemporary and YA fiction trends strongly against prologues. Know your genre's conventions before adding one – a prologue can signal genre fluency or genre confusion depending on whether it fits.
