Dejah Thoris

Character in Edgar Rice Burroughs's Martian novels

Dejah Thoris is a fictional character and princess of the Martian city state/empire of Helium in Edgar Rice Burroughs' series of Martian novels. She is the daughter of Mors Kajak, Jed (chieftain) of Lesser Helium, and the granddaughter of Tardos Mors, Jeddak (overlord or high king) of Helium. She is the love interest and later the wife of John Carter, an Earthman mystically transported to Mars, and subsequently the mother of their son Carthoris and daughter Tara. She plays the role of the conventional damsel in distress who must be rescued from various perils, but is also portrayed as a competent and capable adventurer in her own right, fully capable of defending herself and surviving on her own in the wastelands of Mars.

Except for some jewelry, all of the planet's races seem to eschew clothing and look down upon Earth's inhabitants because they do wear clothing. As Burroughs describes Dejah Thoris:

Dejah Thoris first appeared as the title character in the initial Mars novel, A Princess of Mars (1917). Written between July and September 28, 1911, the novel was serialized as Under the Moons of Mars in the pulp magazine The All Story from February to July 1912. It later appeared as a complete novel only after the success of Burroughs' Tarzan series. For its October 1917 hardcover publication by A. C. McClurg & Company, the novel was retitled A Princess of Mars. She reappeared in subsequent volumes of the series, most prominently in the second, The Gods of Mars (1918), the third, The Warlord of Mars (1919), the eighth, Swords of Mars (1936), and the eleventh, John Carter of Mars (1964). Dejah Thoris is also mentioned or appeared in a minor role in other volumes of the series.

Dejah Thoris has appeared in numerous adaptations of the Martian stories, such as in a 1995 storyline of Tarzan's Sundays comic strip and various comic book series featuring her husband John Carter. She is mentioned in the first issue of The League of Extraordinary Gentlemen, Volume II during a conversation between John Carter and Gullivar Jones.
