Where planetary romance came from

Edgar Rice Burroughs' A Princess of Mars, serialised in 1912, sent the Civil War veteran John Carter to a dying Mars of four-armed warriors, airships and swordfights. It brought the form to a wide audience, sometimes called sword and planet, and Burroughs followed it with series set on Venus and inside the Earth.

Leigh Brackett made Mars her own in the 1940s and 1950s, with stories like The Sword of Rhiannon (1953) full of ancient canals and dead seas. C. S. Lewis' Out of the Silent Planet (1938) gave the form a theological turn, and Jack Vance's City of the Chasch (1968) brought it ironic wit.

As astronomy closed the door on living canals on Mars, the form moved to invented worlds. Anne McCaffrey's Pern books, starting with Dragonflight (1968), Marion Zimmer Bradley's Darkover series and Ursula K. Le Guin's Rocannon's World (1966) all set adventure on colony worlds where science had faded into something like magic.

What separates it from neighbouring subgenres

Planetary romance is defined by its setting and its spirit. A single alien world is the stage, and the story is adventure there: romance in the old sense of the word, full of journeys, sword fights and wonder.

Science Fantasy

Science fantasy mixes technology and magic freely, anywhere. Planetary romance often does too, but it is anchored to one alien world and its cultures.

Sword & Sorcery

Both feature lone swordsmen, decadent cities and exotic danger. Planetary romance moves the action to another planet and swaps sorcery for strange science.

Space Opera

Space opera roams across many worlds and fleets. Planetary romance stays on the ground, on one world, and rarely goes back to orbit.

Space Exploration

Space exploration treats an alien world as something to study and survive. Planetary romance treats it as a place to have adventures, and rarely worries about the science.

Planetary romance kept its canals and swordfights long after astronomers emptied Mars.

How it reads

Expect a hero, often from Earth, plunged into an alien world of warring kingdoms, monsters and ancient ruins. Travel across vast landscapes drives the plot, and the world's cultures are the main attraction. Science is light, and swords often outnumber guns.

The classics are pulpy, fast and colourful, and the Burroughs books in particular reflect their era. Later planetary romances settled into long series exploring one world in depth.



Frequently asked

What is planetary romance?+

Adventure fiction set on an alien planet, with an emphasis on exotic cultures, landscapes and action. 'Romance' here means adventure story, as in the older sense of the word.

What's the difference between planetary romance and sword and planet?+

Sword and planet is a subset: planetary romance in the Burroughs mould, with an Earth hero, swords and princesses. Planetary romance is the wider term.

Where should a new reader start?+

A Princess of Mars is short and fun, though very much of its time. For something more modern, Dragonflight begins the long Pern series.

Is Dune planetary romance?+

It's often described that way, since it's built around one desert planet and its cultures. It's also epic science fiction with a strong ecological and political focus.

Is Pern fantasy or science fiction?+

Science fiction, though it reads like fantasy. Pern is a lost human colony, and its dragons were genetically engineered, which the series reveals over time.
