Llana of Gathol and John Carter of Mars

John Carter was the lead character in the first novel by Edgar Rice Burroughs, set on a fictionalized version of Mars known as Barsoom. 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. Carter 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), the tenth (Llana of Gathol, 1948), and the eleventh and final installment (John Carter of Mars, published posthumously in 1964). John Carter is also a major secondary character in the fourth volume (Thuvia, Maid of Mars, 1920), and the ninth (Synthetic Men of Mars, 1940).
