Purim (Hebrew: פּוּרִים , lit. 'lots') is a Jewish holiday that commemorates the saving of the Jewish people from annihilation at the hands of an official of the Achaemenid Empire named Haman, as it is recounted in the Book of Esther.
According to the Book of Esther, Haman was the royal vizier to the Persian king Ahasuerus (Xerxes I or Artaxerxes I; Khshayarsha and Artakhsher in Old Persian, respectively). His plans were foiled by Mordecai of the tribe of Benjamin, who previously warned the king about an assassination attempt, and Esther, Mordecai's cousin and adopted daughter who had become queen of Persia after her marriage to Ahasuerus. The day of deliverance became a day of feasting and rejoicing among Jews. Although traditionally viewed as a historical document, modern scholarship generally regards the Book of Esther as a historical novel with legendary elements, not a reliable account of Purim’s origins.
