According to the Book of Esther, in the Tanakh, Haman was an Agagite noble and vizier of the empire under Persian King Ahasuerus, generally identified as Xerxes the Great (son of Darius the Great) in the 6th century BCE. Haman and his wife Zeresh instigated a plot to kill all the Jews of ancient Persia. The plot was foiled by Queen Esther, the Jewish Queen of Persia. As a result, Ahasuerus ordered the hanging of Haman and his ten sons. The events of the Book of Esther are celebrated as the holiday of Purim.
