Agamemnon

In Greek mythology, Agamemnon was High King of Mycenae, brother-in-law of Helen of Troy, and commanded the Greek expeditionary force attacking Troy (ancient city) during the Trojan War. To overcome contrary winds for sailing to Troy, he sacrificed his daughter, Iphigeneia.

Agamemnon's dispute with Achilles over the concubine Briseis is central to the Iliad.

On his return to Greece after the Trojan war, Agamemnon's wife Clytemnestra killed him to revenge Iphigenia, and also to prevent his discovering that she had taken a lover (Aegisthus).

Akagamunaš, ruler of Ahhiyawa (i.e. the Achaeans, a Homeric name for the Greeks in the Trojan War) is mentioned in Hittite records of about the right period, so Agamemnon may well have some historical existence.
