Halloween celebrates the old Irish (Celtic) New Year’s Eve. For the ancient Irish, the end of the harvest (and consequent death of the land) came on October 31st, with the new year and new land to begin on November 1st. On this night of transition from one world to the next, it was believed that the spirits of the dead could rise from the grave. One way to avoid being hurt by these spirits was to mask oneself as one of the dead, by wearing masks, etc. It was also customary to ‘bribe’ the dead spirits to leave one safe and sound by giving them candy. Failing to provide a spirit with a ‘treat’ could result in having a ‘trick’ played.
