In Greek mythology, Agamemnon was a Greek hero of the Trojan wars, son of Atreus, king of Mycenae, and brother of Menelaus. He married Clytemnestra, and their children included Electra, Iphigenia, and Orestes. He sacrificed Iphigenia in order to secure favourable winds for the Greek expedition against Troy and after a ten years' siege sacked the city, receiving Priam's daughter Cassandra as a prize. On his return home, he and Cassandra were murdered by Clytemnestra and her lover, Aegisthus. His children Orestes and Electra later killed the guilty couple. Research Agamemnon
