The Warlord of Mars is a science fantasy novel by American writer Edgar Rice Burroughs, the third of his Barsoom series. Burroughs began writing it in June, 1913, going through five working titles; Yellow Men of Barsoom, The Fighting Prince of Mars, Across Savage Mars, The Prince of Helium, and The War Lord of Mars. The finished story was first published in All-Story Magazine as a four-part serial in the issues for December, 1913-March, 1914. It was later published as a complete novel by A. C. McClurg in September, 1919. Plot introduction This novel continues where the previous one in the series, The Gods of Mars abruptly ended. At the end of the previous book, John Carter's wife, the princess Dejah Thoris, is imprisoned in the Temple of the Sun by the vile pretender goddess Issus. It is said one has to wait an entire Barsoomian year before the room the prisoner is in revolves back to the entrance. Plot summary After the battle at the end of the previous book, which ended with the destruction of the religion of Issus, John Carter's wife and two other women were locked in a slowly rotating prison attached to the Temple of the Sun, each of whose hundreds of cells are only open to the outside world once every year. In the meantime, Carter's friend Xodar has become the new Jeddak (chief or king) of the black Martian First Born, and those white Martian therns who reject the old religion likewise gain a new unnamed leader, but there are still some who wish to keep the old discredited religion going, including the therns' erstwhile leader, the Holy Hekkador Matai Shang. John Carter discovers that a First Born named Thurid knows the secret of the Temple of the Sun and he and Matai Shang want to rescue the Holy Thern's daughter Phaidor, who has been imprisoned with Dejah Thoris and another Barsoomian princess, Thuvia of Ptarth, in the Temple jail for several hundred days. Thurid, to spite Carter, gets Matai Shang to also take Dejah Thoris and Thuvia along with them. Carter follows them in the hope of liberating his beloved wife. His antagonists flee to the north, taking the three women along. (This resolves the cliffhanger from the previous book, in which Phaidor attempts to stab Dejah Thoris; apparently, Thuvia successfully disarmed Phaidor, and nobody was killed.)
