Purim is a Jewish holiday that celebrates the saving of the Jewish people from Haman's plot to kill all the Jews in the Persian Empire. The story of Purim takes place in the land of Shushan and is told in the Book of Esther, which is read during Purim often in a comical or dramatic play. The story tells the tale of King Achashverosh, his evil adviser Hamen, the courageous Mordechai and his cousin Esther who stood up to the king and helped save her Jewish people.
The holiday traditions include getting dressed up to hear the story; celebrating with sweets (hamentaschen) and giving baskets of these treats and small gifts to friends (Mishloach Manot); and (for grown ups!) drinking until you can't decipher the difference between Haman and Mordechai in the Purim story. The holiday is celebrated with feasting and rejoicing and can be a fun holiday to celebrate for the entire family.
