A Princess of Mars
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 &amp; Company, the novel was retitled "A Princess of Mars."
