Athaliah (Man living at the time of Divided Monarchy)

Athaliah was Ahab and Jezebel's daughter, married into Judah's royal line, and when her son King Ahaziah was killed she seized the throne for herself by murdering nearly the entire royal family, the only woman to ever rule Judah in her own name. She reigned six years worshiping Baal in Jerusalem until the priest Jehoiada revealed that one grandson, the infant Joash, had survived, and staged a coup that ended with Athaliah's execution.
