Agamemnon

Agamemnon is the son of Atreus and the brother of Menelaus.  He was the king of either Mycenae (in Homer) or of Argos (in some later accounts), and during the Trojan War he was the leader of the Greek forces. He married Clytemnestra and had several children by her, including Orestes, Electra, and Iphigenia.
