In Trojan War mythology, Agamemnon was the Greek leader said to sacrifice Iphigenia at Aulis.
Iphigenia was Agamemnon’s daughter and the daughter of Clytemnestra. According to myth, Artemis stopped the Greek fleet’s winds after Agamemnon offended her, and the goddess demanded Iphigenia as compensation before the ships could sail.
The versions differ significantly. In Euripides’ plays, Iphigenia is associated with a sacrifice at Aulis, while another tradition says Artemis substituted a deer and carried her away to become a priestess at Tauris. These variations are part of the mythology rather than a single consistent narrative.
The story also explains the deep hostility Clytemnestra later feels toward Agamemnon. That family conflict becomes central in Greek tragedy after the king returns from Troy.
