Stories in the sword and planet genre fall primarily into two chronological classes.
The first includes the stories of Burroughs himself and his early imitators, of whom Otis Adelbert Kline was the most significant.
In A Princess of Mars, John Carter, a Confederate officer and soldier, has taken up prospecting in Arizona after the war to regain his fortune. Under mysterious circumstances, he is transported to Mars, called Barsoom by its inhabitants. There he encounters savage and monstrous aliens, a beautiful princess, and a life of adventure and wonder. Burroughs followed up this first book with several more Barsoom stories, and another series that could be considered Sword & Planet, featuring as hero Carson Napier and his adventures on Venus, natively known as Amtor. Burroughs' Pellucidar series could arguably be considered sword-and-(inner) planet, as it follows most of the plot conventions described below.
The second and larger group includes authors who began to write Burroughs pastiches from the mid-1960s to early 1970s. Such authors included Lin Carter and Michael Moorcock. Except for continuations of the extended Dray Prescot and Gor sequences, and occasional parodies of earlier series, not many new works in the genre have appeared from major publishers since 1980. One notable exception are two books by S. M. Stirling, published by Tor, The Sky People, (2006) and In the Courts of the Crimson Kings (2008). Smaller presses have continued to issue new works in the genre, though, most notably Wildside Press, primarily through The Borgo Press imprint. In 2007, for example, Wildside/Borgo published a new book in Charles Nuetzel's Torlo Hannis of Noomas series, and printed the Talera trilogy by Charles Allen Gramlich (Charles Gramlich).
