You've probably already bought your Halloween costume, but have you ever wondered why we dress up each year? Where did trick-or-treating come from, anyway? Check out these 10 Things You Didn't Know about Halloween!
It Started as Samhain
Halloween has been traced all the way back to an ancient Celtic festival called Samhain (pronounced sow-in,) that took place 2,000 years ago. Samhain was observed with large bonfires and the wearing of costumes, much like Halloween today.
