Klytemnestra was the daughter of Tyndareus and Leda. Klytemnestra was the wife of Agamemnon and mother of Iphigeneia, Orestes, Khrysothemis, and Elektra through him. Agamemnon was leading Greek forces in the Trojan War in Troy. However, consistently weak winds prevented his ships from sailing. Through a subplot involving the gods, he was told that the winds would return if he sacrificed his daughter Iphigeneia to the goddess Artemis. He persuaded Klytemnestra to send Iphigeneia by deceptively telling her that the purpose of his daughter's visit was to marry her to Akhilles. When Iphigeneia arrived, she was sacrificed. Klytemnestra learned of this event and grieved for her daughter.
