Halloween started in Ireland as a pagan holiday for people to celebrate the spirits of their ancestors. Then many, many years later people started dressing into costumes to sc â¦ are away evil spirits. Now in this day in age it is a known holiday for children of some countries to dress up and get candy.
Halloween has a murkey history, with historians pointing to several traditions as the origin of the holiday. The most costumed and spooktacular event of the year is far from what originators celebrated centuries ago on October 31. The modern-day developments of Halloween â with its candy, haunted decorations and risque costumes â stem from a blending of traditions. Ancient festivals and remembrances of the dead on the end of October first spawned Halloween. Subsequent celebrations from cultures that believed the living collided with the dead on this date contributed to the now classic customs of the dark holiday. Take a look back on the evolution of Halloween with this timeline: Over 2,000 years ago: While unknown specifically when, itâs believed that Halloween descended from a Celtic festival dating back at least 2,000 years. Known as Samhain, the ancient celebration marked the end of the harvest season on October 31. Pagans believe it to be a day of overlap between the living and the dead.
