Halloween traditions have roots in a Celtic pagan festival called Samhain, traditionally held between the fall equinox and winter solstice to mark the harvest. It was seen as a time of transition when spirits could rise and roam the earth. To ward them off, Celts lit bonfires and wore fearsome costumes.
In the eighth century, after Pope Gregory III devoted November 1 to honoring saints, Samhain traditions became All Saints’ Day festivities, and the night before was known as All Hallows’ Eve, eventually Halloween. Like St. Patrick’s Day, the holiday took on a new life after Irish immigrants brought it to the US in the 19th century. Today, America’s over-the-top celebration of costumes, candy, and spooks has helped redefine Halloween worldwide.
