Purim (; פּוּרִים , lit. 'lots'; see Name below) 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 (usually dated to the late-5th or 4th centuries BCE). Haman was the royal vizier to the Persian king Ahasuerus (Xerxes I or Artaxerxes I; Khshayarsha and Artakhsher in Old Persian, respectively). https://en.wikipedia.org/wiki/Purim
