A Princess of Mars

John Carter, a Confederate veteran of the American Civil War, goes prospecting in Arizona immediately after the war's end. Having struck a rich vein of gold, he runs afoul of the Apaches. While attempting to evade pursuit by hiding in a sacred cave, he is mysteriously transported to Mars, called "Barsoom" by its inhabitants. Carter finds that he has great strength and superhuman agility in this new environment as a result of its lesser gravity. He soon falls in with the Tharks, a nomadic tribe of Green Martians, as the planet's warlike, six-limbed, green-skinned inhabitants are known. Thanks to his strength and combat abilities, Carter rises to a high position in the tribe and earns the respect and eventually the friendship of Tars Tarkas, one of the Thark chiefs.
