In Greek mythology, Helen of Troy, also known as Helen of Sparta, was the daughter of Zeus and Leda, and was a sister of Castor, Pollux, and Clytemnestra. In Greek myths, she was considered the most beautiful woman in the world. By marriage she was Queen of Laconia, a province within Homeric Greece, the wife of King Menelaus. Her abduction by Paris, Prince of Troy, brought about the Trojan War. Elements of her putative biography come from classical authors such as Aristophanes, Cicero, Euripides and Homer. In her youth she was abducted by, or eloped with, Theseus, and in some accounts bore him a child. A competition between her suitors for her hand in marriage sees Menelaus emerge victorious. An oath sworn beforehand by all the suitors requires them to provide military assistance in the case of her abduction; this oath culminates in the Trojan War. When she marries Menelaus she is still very young; whether her subsequent involvement with Paris is an abduction or a seduction is ambiguous. The legends recounting Helen's fate in Troy are contradictory. Homer depicts her as a wistful, even a sorrowful, figure, coming to regret her choice and wishing to be reunited with Menelaus.
