Agamemnon is a mythical king of Mycenae. During the Trojan War, as described in Homer's Iliad, Agamemnon was the Supreme commander of the Greek forces. He was a member of the House of Atreus, which is considered to have been cursed due to its violent history, and was brother to Menelaus, king of Sparta. With his wife, Clytemnestra, Agamemnon had four daughters: Chrysothemis, Electra, Iphianissa, and Iphigenia; he also had one son, Orestes.
During the Trojan War, Agamemnon sacrificed Iphigenia to Artemis, to ensure strong winds for the voyage to Troy. During the war, he captured Priam's daughter, Cassandra, and brought her back to Mycenae with him. However, upon his return, he discovered that Clytemnestra had taken a new husband, Aegisthus. Clytemnestra killed both Agamemnon and Cassandra after luring them to a banquet.
