Greek Myth
Electra was the daughter of Agamemnon and Clytemnestra. After their father was murdered, she sent her brother Orestes away in order to save his life. Later on, her brother came back to avenge Agamemnon's death, and the brother and sister killed their mother, as well as her lover Aegisthus.

Modern Reference
Opposite of the Oedipus Complex, there is the Electra Complex, developed by Jung and somewhat rejected by Freud (Freud used a different term, feminine Oedipus attitude). This theory suggests that the female child becomes attached to the father once she realizes she is without male sex organs, and then feels resentment towards her mother.This Electra Complex relates back to the story of Electra, who seeks revenge over her father's murder by killing her mother and her mother's lover.
