Purim 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.
According to the Book of Esther, in the Hebrew Bible, Haman, royal vizier to King Ahasuerus, 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 reciprocal gifts of food and drink, giving charity to the poor, a celebratory meal, and public recitation of the Scroll of Esther, additions to the prayers and the grace after meals. Other customs include drinking wine, wearing of masks and costumes, and public celebration.
Wearing masks and costumes is main and most extincting part for the kids.
