Steampunk is a genre defined by an aesthetic rather than a mechanic: a world built on steam power, clockwork, brass, and airships, usually set in an alternate nineteenth-century industrial age that developed its machines along a different line than ours did. It can lean science fiction or fantasy, but the brass-and-gears look and the age-of-steam setting are what make a story steampunk, not any particular plot or power system.
What does steampunk actually mean?
Steampunk is a genre and aesthetic in which the technology of the industrial revolution is pushed further, stranger, or sideways, so that steam engines, clockwork, and brass machinery do the work that electronics and computers do in our own world. The classic image is a Victorian or roughly nineteenth-century setting threaded with airships, mechanical automatons, pneumatic tubes, and gear-driven contraptions, all of it running on coal, steam, and springs rather than silicon. What unifies the genre is not a particular story engine, the way LitRPG is unified by game mechanics or cultivation is unified by a ladder of power, but a look and an alternate-history premise: the age of steam kept going, and this is the world it made.
That distinction matters more than it sounds, and it is the thing that confuses most newcomers. A lot of the genres I have written about on this blog are defined by how they work. Steampunk is defined by how it feels and where it is set. You can have a steampunk murder mystery, a steampunk war epic, a steampunk romance, or a steampunk coming-of-age story, and they are all steampunk because of the brass and the boilers, not because they share a plot shape. If you want the wider family these labels belong to, I keep a map of the territory in the web fiction genres guide; steampunk sits in the corner where setting and aesthetic, rather than mechanic, do the defining.
Where does steampunk come from?
The word steampunk was coined around 1987 by the author K.W. Jeter, in a letter to the science fiction magazine Locus, and he meant it half as a joke. Jeter, along with Tim Powers and James Blaylock, had been writing fantastical novels set in a Victorian London of mad science and strange machines, and he reached for a label that riffed on cyberpunk, the term then attached to William Gibson's near-future, high-technology fiction like Neuromancer (1984). Cyberpunk had computers and street-level grit; the Victorian stuff had steam, so, steampunk. The name was a bit of fun that happened to describe something real, and it stuck so thoroughly that it eventually outgrew the handful of books it was invented to label.
But the roots go back much further than the 1980s, which is worth knowing if you want to write in the mode honestly. The deep ancestors are the Victorian "scientific romances" themselves, the actual nineteenth-century writers imagining what their own machine age might become. Jules Verne gave us the submarine Nautilus in Twenty Thousand Leagues Under the Sea (1870) and the circumnavigating obsession of Around the World in Eighty Days, and H.G. Wells gave us The Time Machine (1895) and the invading tripods of The War of the Worlds (1898). Further back still, Mary Shelley's Frankenstein (1818) sits at the headwaters as the first great story of science reaching past its grasp. My feeling is that steampunk is best understood as the modern genre looking back fondly at that era and asking the question those writers could not quite ask themselves, which is what their century would have looked like if its inventions had run wild.
What are the hallmarks of a steampunk story?
The surface markers of steampunk are the easiest part to name and the most fun to deploy: airships and dirigibles drifting over a smoke-choked city, clockwork automatons and mechanical men, difference engines and analytical machines standing in for computers, goggles and brass and leather and soot, and a social world that still runs on the manners, class lines, and empires of the nineteenth century. The 1990 novel The Difference Engine, by William Gibson and Bruce Sterling, is the book most often credited with bringing steampunk to mainstream science fiction attention, and it does the signature move cleanly: it imagines that Charles Babbage's mechanical computer actually got built and working, and follows the consequences out into an altered Victorian Britain. That is the whole genre in miniature, one real technology nudged forward, and a world reorganized around it.
Underneath the brass, though, the stories that last tend to do something with the setting rather than just wear it. Philip Reeve's Mortal Engines (2001) turns the age of machines into enormous predator cities that roll across a ruined earth eating each other, which is steampunk as ecological fable. China Miéville's Perdido Street Station (2000), usually filed under steampunk and the New Weird both, uses its grimy industrial city of New Crobuzon to stage questions about labor, bodies, and power. Scott Westerfeld's Leviathan (2009) rebuilds the First World War as a clash between clanking Austro-German war machines and living British bioengineered airships, and Cherie Priest's Boneshaker (2009) drops a walled, gas-poisoned Seattle into the genre's map. Even outside prose, Alan Moore and Kevin O'Neill's comic The League of Extraordinary Gentlemen (1999) and Hayao Miyazaki's films, especially Castle in the Sky (1986) with its airships and floating city, have done as much as any novel to fix the look in people's minds. The lesson I draw from all of them is that the aesthetic buys you attention, but the alternate-history argument, the "here is what this machine did to this society," is what buys you a reader for three hundred chapters.
How is steampunk different from its neighbors?
Steampunk is distinct from its nearest genre neighbors because it is defined by an industrial-era aesthetic, where they are defined by setting-type, tone, or mechanic. The confusion usually comes from the fact that steampunk often shares a world with magic, which makes people file it next to fantasy and then struggle to tell the shelves apart. The honest answer is that the labels are answering different questions. Urban fantasy hides the fantastic inside our own recognizable modern world, the here-and-now with a secret magical layer underneath; steampunk reimagines an earlier, industrial world's technology and makes the strangeness the visible texture of everyday life, not a hidden secret. High fantasy builds a wholly invented, usually pre-industrial secondary world; steampunk is anchored to the look and the social machinery of the age of steam, whether it sets that in an altered version of real Victorian Earth or in a secondary world that reached its own industrial revolution.
The cleaner way to hold it, I think, is to separate the genre from its engine. When the odd machines in a steampunk story run on extrapolated science, as Babbage's engine does in The Difference Engine, you are reading alternate-history science fiction wearing steampunk clothes. When magic shares the workshop with the boilers, you are reading what the field often calls gaslamp fantasy, which is the same gaslit nineteenth-century backdrop with the fantastical element coming from sorcery rather than invented engineering. Steampunk is also the eldest of a whole family of "-punk" aesthetics that followed it, dieselpunk reaching for the machine age of the 1920s to 1940s, cyberpunk running the other direction into the near-future wires it was originally named against, and I find it useful to tell writers that these are all the same move, which is "take a technological era and push its defining machine until the world bends." Steampunk just happens to have planted its flag in the century of coal and steam.
Should you write a steampunk web serial?
Steampunk suits serialized web fiction unusually well, and I would encourage anyone drawn to the aesthetic to try it in the long format. Running a web fiction platform, I see the steampunk tag turn up steadily, and the stories that work tend to share a quality: they treat the invented technology and the alternate world as a place to be explored slowly, over many chapters, rather than explained in a single info-dump. A serial gives you room to let a reader learn the rules of your difference engines, wander the districts of your brass city, and come to understand the guild politics and airship navies the way they would a real place, which is exactly the kind of accumulating detail the format rewards and a single novel often has to compress.
The real hazard, and it is a serious one in this genre specifically, is continuity. Steampunk lives on invented detail, and the more distinctive your world's technology is, the more ways there are for it to quietly contradict itself across a long run. If your clockwork automatons cannot operate in the rain in chapter twelve, that had better still be true in chapter two hundred, and if your empire's airship fleet is coal-choked and slow early on, a sudden fast fleet later needs a reason the reader can see. This is where I think a purpose-built tool earns its place over a scattered pile of notes files. In the IlorisNovel editor the wiki stays connected to the manuscript, so the rules of your fictional technology, the factions and their rivalries, and the shape of your alternate world live in one place you can check against as you draft, and a timeline keeps the sequence of inventions and events honest. You can feel out whether that kind of connected world-building fits how you work by trying the editor with no account, which is the lowest-friction way to see whether a long steampunk serial is something you want to commit to. The brass and the goggles are the easy, pleasurable part; the thing that separates a steampunk world a reader believes from one they stop trusting is whether its machinery holds together from the first chapter to the last.
Common questions about steampunk
Is steampunk science fiction or fantasy?
Steampunk is defined by its setting and aesthetic, not by whether magic exists, so it can be either. When the strange machines run on extrapolated science, as in Gibson and Sterling's The Difference Engine, it reads as alternate-history science fiction. When magic shares the workshop with the boilers, it reads as fantasy, often called gaslamp fantasy. The brass, steam, and age-of-industry look is the constant across both; the engine underneath is what shifts a given story toward one shelf or the other.
Where did the word steampunk come from?
The author K.W. Jeter coined steampunk around 1987 in a letter to the magazine Locus, half in jest, to name the Victorian-set stories he, Tim Powers, and James Blaylock were writing. He was riffing on cyberpunk, the term then attached to William Gibson's near-future fiction. The joke stuck, and a loose description of a few novels gradually hardened into the name of a whole genre and a sprawling aesthetic movement that now reaches well beyond books.
What is the difference between steampunk and gaslamp fantasy?
Both share the nineteenth-century look, but the emphasis differs. Steampunk foregrounds invented machinery, steam engines, clockwork automatons, and mechanical computers, as the thing that makes the world strange. Gaslamp fantasy foregrounds magic set against the same gaslit Victorian backdrop, with the technology kept mostly period-accurate. In practice the two blur constantly, and plenty of stories sit comfortably under both labels at once, so I would not lose sleep over policing the border.
What makes a story steampunk rather than just historical Victorian fiction?
The divergence is what matters. Plain historical fiction keeps the real nineteenth century intact; steampunk asks what if the age of steam had gone further or sideways, and builds a world where airship fleets, mechanical computers, or clockwork prosthetics are ordinary. A useful test is to imagine deleting the invented technology: if the story would be unchanged, you have Victorian fiction with set dressing, but if removing the machines collapses the plot, you have genuine steampunk.
Can you write steampunk web fiction?
Yes, and the serial format suits it unusually well, because steampunk lives on invented detail, a city of brass and soot, a guild of engineers, an airship navy, that rewards being explored over many chapters rather than dumped at once. The main risk is continuity: the rules of your fictional technology and the map of your alternate world have to stay consistent across a long run, which is why a connected wiki that holds your tech rules and factions is worth more in this genre than in almost any other.
