#11: Clytemnestra (Approx. 12th Century BC)
Clytemnestra had a long memory. While Agamemnon was off fighting in the Trojan War, she spent a decade furious over his sacrifice of their daughter, Iphigenia. By the time he returned around 1180 BC, she had taken Aegisthus as her partner. Together, they trapped Agamemnon in a net during his bath and killed him, turning his homecoming into a carefully planned act of revenge.
