Agamem′non, the leader of the Greeks in the Trojan war. He was the son or grandson of Atreus, king of Mycenæ, and the most powerful prince in Greece. He and his brother Menelaus married the two daughters of the king of Sparta, Clytemnestra and Helen. When the Trojan Paris carried off Helen, Agamemnon was chosen chief of the forces sent out for her recovery. At Troy, in the ninth year of the war, he quarreled with Achilles over two captive maidens, and almost ruined the Greek cause. After his return from the capture of Troy, he was murdered at a feast by his wife and her lover. His death was afterward avenged by his son Orestes. Agamemnon was worshiped in Sparta as a god.
