Julia Quinn was studying at Harvard when she started writing Regency romance novels. Her first Bridgerton book, The Duke and I, came out in 2000, and for twenty years the series sold quietly and steadily, building the kind of readership that doesn't require a cultural moment to sustain itself. Then Netflix adapted it in 2020 and suddenly everyone was talking about Quinn as if she'd appeared out of nowhere. She hadn't. She'd been writing dialogue in drawing rooms for two decades, and the 25 million copies the series eventually sold didn't come from the show. They came from the fact that her characters sound like they belong to their century without sounding like they're performing it.
That's the central problem of historical romance, I think. You're writing people who lived under different rules, different assumptions about what could be said and who could say it, and you have to make the reader feel the weight of those rules without burying the story under research. The writers who do this well tend to share a few habits. They aren't the habits I expected.
Regency dialogue is a game with rules the characters are trying to break
Quinn has talked about her approach to Regency dialogue, and the thing that sticks with me is how deliberate the constraints are. She avoids words that didn't exist in the early 1800s but also avoids words so archaic that a modern reader would trip over them. What she's writing isn't historically accurate speech. It's the rhythm of formal speech, stripped of anything that would pull you out of the scene.
The Bridgerton novels work because the formality isn't decoration. It's a system of pressure. When a character in a Quinn novel says exactly what they mean, it hits harder because everyone around them has been speaking in careful indirection for two hundred pages. The banter between her leads isn't witty in spite of the etiquette. It's witty because of the etiquette. Every honest sentence is a small act of rebellion against a social code that demands you never say the real thing out loud.
I think about this whenever I read historical romance dialogue that feels flat. Usually the problem isn't that the words are wrong for the period. It's that the writer hasn't built the cage tightly enough for the words to rattle against. If your characters can say whatever they want whenever they want, you've lost the tension that makes Regency dialogue worth reading. The subtext disappears. You're left with modern people in old clothes.
The heroine's cause and the romance should need each other
Evie Dunmore's Bringing Down the Duke opens with a Scottish suffragist arriving at Oxford in the 1880s. She's there on a scholarship that requires her to recruit men of influence to the women's suffrage cause. The duke she targets happens to oppose everything she stands for politically. And the romance that develops between them isn't separate from that political conflict. It is the political conflict.
Dunmore grew up in Germany and studied in the UK, and her League of Extraordinary Women series treats the suffrage movement the way a fantasy novel treats its magic system. It's woven into every scene, every decision, every cost. The heroine can't fall in love with the duke without compromising her cause. The duke can't support the heroine without dismantling his own position. Neither of them can have what they want without something real giving way.
What interests me about this approach is that it solves a structural problem most historical romance writers fight with: what to do with the heroine's life outside the romance. In a lot of period fiction, the love story and the heroine's personal ambitions run on parallel tracks that occasionally touch but never really merge. Dunmore welds them together so completely that you can't tell where the politics end and the love story begins, and that's what makes the stakes feel genuine. Neither half works alone.
