Many of the customs linked to Halloween come from very old traditions.
Going door to door to collect treats come from Ireland hundreds of years ago when groups of farmers used to do it collecting goods for a village feast. Those who gave were promised prosperity; those who didn’t received threats of bad luck.
The Jack-o-Lantern, which is a pumpkin with a candle inside, comes from an Irish legend about Jack, a man who never did anything good in his life and was forced by the devil to roam the earth looking for a place to rest with only a coal burning inside a pumpkin to light his way.
Halloween is a very traditional celebration in the USA and some other countries. It is celebrated on October 31st.
According to the tradition, the Druid Priests of ancient Britain believed that witches, demons and spirit of dead people, used to roam on the eve of November First, which marked the end of summer, the harvest time and the beginning of a new year. To protect themselves from bad spirits, the Druids offered them things to eat and disguised with masks.
The name Halloween comes from another tradition. The Catholic Church designed the first day of November to honor all Saints, or Hallows. The night before All Saints was called “All Hallows Even” and the expression was shortened to Halloween.
Nowadays every year on October 31, a group of noisy children dressed as ghosts and witches may knock on your door holding a bag. They ring the bell and you ask:” What do you want?” They shout “Trick or Treat”. Then you should give them candies or some money or they’ll put some dirt on your home walls.
Nowadays this activity is restricted to relatives and friends houses because it’s too dangerous for little children to knock on unknown people doors
