In Greek mythology, Agamemnon was the king of Mycenae or Argos (it is thought to be different names for the same area).
When Helen, the wife of Menelaus (Agamemnon’s brother), was abducted by Paris of Troy, Agamemnon commanded the Greek armed forces in the ensuing Trojan War.
Agamemnon was the commander-in-chief of the Greeks during the Trojan War. During the fighting, Agamemnon killed Antiphus and 15 other Trojan soldiers.
