1. Trick or Treating used to be very different.

One of the best parts of Halloween is getting to go trick-or-treating with your family or friends. Getting candy and trading for your favorites the next day is something the majority of kids remember the best from childhood. Originally, though, trick or treating was a tradition where poor people would go door-to-door asking for food or money in exchange for song and prayers. If these people were denied food, the house would receive a trick.

2. Costumes weren't originally just worn for fun.

Halloween's origins trace back to the Celts' festival of Samhain, where demons and ghosts roamed the Earth due to the belief that the barrier between our world and their world was thinnest then. People used costumes as a defense barrier in order to disguise themselves so they'd be protected from any ghouls roaming on that night.

3. Jack-o'-lanterns have transformed over the years.

Originally jack-o'-lanterns weren't made from pumpkins; they used to be formed from turnips! The story of how the lanterns got their name came from a myth that told of a man named Jack who tricked the devil several times and, as punishment, was denied entrance to both heaven and hell and as a result was condemned to wander the earth, using his lantern to lead people off their paths.

4. Halloween has been around longer than most realize.

While the current version of Halloween has evolved over the years, it is believed that the earliest origins of the holiday began 2,000 years ago with the Celtic celebration of Samhain.
