Agamemnon was the king of Mycenae in Greece who led the Greek forces in the Trojan War. He had a troubled family history marked by murder and incest. As the commander of the Greek armies, he sacrificed his daughter Iphigenia to appease the goddess Artemis so the winds would allow the fleet to sail. During the war, he angered Achilles by taking a slave from him. When he returned home victorious from Troy, his wife Clytemnestra and her lover Aegisthus killed him in revenge for Iphigenia's death. His son Orestes later avenged the murder.
