A Princess of Mars
The novel originated several enduring Martian tropes in science fiction writing. These include Mars being an ancient world, nearing the end of its life, being the home of a superior civilisation capable of advanced feats of science and engineering, and also being a source of invasion forces, keen to conquer the Earth. The first two tropes were prominent in Edgar Rice Burroughs's "Barsoom" series beginning with "A Princess of Mars" in 1912.
