In Greek mythology, Agamemnon was the son of king Atreus and queen Aerope of Mycenae, the brother of Menelaus, the husband of Clytemnestra as well the father of Iphigenia, Electra, Orestes and Chrysothemis. Mythical legends make him the king of Mycenae or Argos, thought to be different names for the same area. When Helen, the wife of Menelaus, was abducted by Paris of Troy, Agamemnon commanded the united Greek armed forces in the ensuing Trojan War.
On Agamemnon’s return from Troy he was murdered (according to the fullest version of the oldest surviving account, Odyssey 11.409–11) by Aegisthus, the lover of his wife Clytemnestra. In old versions of the story: “The scene of the murder, when it is specified, is usually the house of Aegisthus, who has not taken up residence in Agamemnon’s palace, and it involves an ambush and the deaths of Agamemnon’s followers too”. In some later versions Clytemnestra herself does the killing, or they do it together, in his own home.
