Hippolyta
Theseus, believed either to be in the company of Heracles, or of his own accord, had journeyed to the land of the Amazons, a race of all-female warriors who had sex with men for reproduction but killed or banished any male children born. Sensing no trouble or malice from Theseus, the Amazons decided to welcome him by having the queen Hippolyta go aboard his ship bearing gifts. After boarding the ship, Theseus left for Athens, claiming Hippolyta as his bride. This sparked a war between the Amazons and the Athenians. Hippolyta eventually bore a son for Theseus, whom they named Hippolytus (Ἱππόλυτος). Theseus lost his love for Hippolyta, however, after he had seen Phaedra.
Plutarch's Life places Hyppolyta's Amazonian sister, Antiope, as the Amazonian kidnapped by Theseus. In this account, Antiope is the mother of Hyppolytus (named after her sister).
