The Telnarian Histories are a series of five space opera novels by American writer John Norman; the first three were published between 1991 and 1993. The setting of the novels is a galactic realm closely parallel to the later history of the Roman Empire and its wars with Germanic barbarians. The ruling family of the empire is human, but extraterrestrials exist, while individuals pursue destinies of freedom and slavery. The depiction of slavery in the books resembles that found in the Gor series, with female slaves dominated by male masters.
