How to Write a Historical Novel

A historical novel is a story set in a real past that treats the period as a live force rather than a backdrop. The craft problem is a double one: the book has to be a novel first — with a protagonist who wants something and can't have it — and yet the world it moves through has to feel researched, specific, and not-now. Most historical fiction fails on one side or the other. It becomes a costume drama with modern people in it, or it becomes a research report with a thin plot laid over the top.

Choose a period you can hear

Start narrower than you think. "The Middle Ages" is not a setting; a particular decade, place and social layer is. The narrowing matters because the details you need are not the famous ones — they're the mundane ones: how long a journey takes, what a day's wage buys, who can enter a room without knocking, what happens to a woman who leaves her household. Those are the facts that make prose feel period. Battles and coronations are the easy part.

It also helps to pick a period whose voice you can hear. Historical fiction lives or dies on the reader believing the interior of a mind from another century. If you can't imagine what your protagonist would find shocking, funny, or unremarkable, you'll write a modern person in a costume, which is the commonest way the genre fails.

Research until it's boring, then stop

The useful test is whether the period has become ordinary to you. While every fact still feels exciting, you'll want to put it all on the page. Once the texture is unremarkable, you can select.

Practical shape for a first pass:

  • The spine: one solid narrative history of the period, to get chronology and cause straight.
  • The texture: something on daily life — food, money, clothing, work, medicine, law.
  • The voices: primary sources. Letters, diaries, court records, sermons, recipes, ballads. This is where the mindset lives, and no secondary source substitutes for it.
  • The map: geography and travel times. Distance is a plot constraint and writers routinely get it wrong.

Then keep a research file with the source next to every fact, because at revision you will need to know whether something is documented or something you assumed in month two.

The counterweight to all this is the iceberg. Research earns its keep by making you confident, not by appearing. A scene that stops to explain the guild system has stopped being a scene. If a fact doesn't press on a character's decision, it belongs in your notes, not the chapter.

Accuracy, and when story wins

There is a spectrum, and it's worth deciding where your book sits before you write, because readers will hold you to it.

Kind of fact How much licence Practical rule
The documented record (dates, outcomes, who was where) Very little Change it and an informed reader stops trusting you
Undocumented gaps (private conversations, motives, inner life) This is the novel Invent freely, consistent with what is known
Mundane texture (a meal, a street, a minor official) Broad Be plausible for the period; few readers will check, though the specialists will
Compression (merging two campaigns, one composite servant) Common, but declare it Standard practice; note it in an author's note
Language Broad but constrained Modern, readable prose; avoid words whose concepts postdate the period

The last row is the subtle one. Anachronism is usually conceptual, not lexical. A medieval character can't think about "trauma" or "the economy" as we understand them, even in words that existed. Meanwhile, fake-archaic dialogue ("prithee, good sir") ages worse than clean modern sentences. Plain prose with a period-consistent content of thought is the safest default — though it isn't the only route: novelists from Patrick O'Brian to Paul Kingsnorth have built period diction, or an invented one, into the texture of the prose itself. What's hard to defend is pastiche: archaic decoration over a modern mind.

Real people on the page

Using documented figures is a long tradition and it is not, in itself, a problem — but the leash shortens with fame. Hilary Mantel's Wolf Hall takes Thomas Cromwell, a man with a heavy public record and almost no recorded interior, and builds the novel in exactly the gap the record leaves. That's the model: find where the documents stop, and write there.

Umberto Eco's The Name of the Rose runs the plot the other way round — an invented murder mystery inside a meticulously reconstructed fourteenth-century abbey, where the period's real intellectual quarrels, and several of its real churchmen, supply the stakes. And Robert Graves's I, Claudius shows how far a novelist can go inside the gaps of a well-known chronology: Graves follows the Roman historians for the sequence of events, then invents freely in their rumour and silence — Livia the serial poisoner is largely Graves's construction — while a first-person narrator's voice makes a familiar history feel like news.

If the plot requires a real person to do something they demonstrably didn't, either fictionalize them into an invented character, or accept it and say so in an author's note. Readers of this genre are forgiving of declared licence and merciless about undeclared error.

Common mistakes

Mistake Why it hurts Fix
The research dump Hard-won facts stop the story to be admired Cut to the fact that changes a decision; the rest stays in your notes
Modern morality in period clothes A protagonist with twenty-first-century values is a tourist Give them period assumptions and let the conflict come from where they strain against them
The tour-guide narrator Characters explaining their own world to each other ("As you know, the King…") Let the reader infer; unexplained detail reads as real
Costume-drama dialogue Fake-archaic speech distances rather than immerses Write clear modern prose; period the thought, not the syntax
Only the famous parts A period reduced to its greatest hits feels like a textbook Anchor in the mundane — work, food, money, weather
No plot under the period Atmosphere isn't structure Make sure your protagonist wants something the period will not give them

The best single test: could this story be told, unchanged, in another century? If yes, the history is decoration. The period should be doing something — creating the obstacle, closing the exit, making the choice costly.

Keeping a period straight while you draft

Historical fiction generates two piles of material — the manuscript and everything you learned to write it — and the discipline is keeping them apart without losing either. Writer Studio splits them by design. The manuscript sits on a structural spine (book → part or act → chapter → scene), while research, sources and cut material live in book notes: free-form documents that open like any other tab, are covered by project search, and whose words never enter your word counts, writing goals or exports. Characters and locations live in the Book Wiki as entities with aliases, a summary and a description, linked to the scenes where they appear, which is how you check a minor official's title is the same in chapter twenty as it was in chapter three. Tags — one project-wide set, with colour dots in the tree — are useful as a fact-checking layer: mark every scene resting on an unverified claim and filter the project by that tag when the sources arrive. For the pass where you separate documented fact from what you assumed, the revision tools — issues raised against a scene, chapter or entity, revision notes, and scene statuses — are the place for it. Worth knowing what's not there yet: a proper timeline of events isn't built — it's still on the roadmap — so a chronology of real dates against your fictional plot currently belongs in a note. Writer Studio is free, local-first and in alpha, on macOS, Windows and Linux, and it exports to DOCX, EPUB and FB2 when the draft is ready to leave the desk.

A historical draft carries a second manuscript's worth of research behind it — download Writer Studio if you'd rather your sources sat beside the book than on top of it.

Historical fiction borrows machinery from its neighbours — a period mystery is still a mystery, and a court is a place of intrigue:
