Purim (Hebrew: פּוּרִים (help·info) Pūrīm "lots", from the word pur,related to Akkadian pūru) is a Jewish holiday that commemorates the deliverance of the Jewish people in the ancient Persian Empire from destruction in the wake of a plot by Haman, a story recorded in the Biblical Book of Esther (Megillat Esther).
According to the Book of Esther, in the Hebrew Bible, Haman, royal vizier to King Ahasuerus (presumed to be Xerxes I of Persia), planned to kill all the Jews in the empire, but his plans were foiled by Mordecai and his adopted daughter Queen Esther. The day of deliverance became a day of feasting and rejoicing.
Purim is celebrated by giving mutual gifts of food and drink (mishloach manot), giving charity to the poor (mattanot la-evyonim), a celebratory meal (se'udat Purim), and public recitation of the Scroll of Esther (keriat ha-megillah), additions to the prayers and the grace after meals (al hannisim).Other customs include drinking wine, wearing of masks and costumes, and public celebration.
