The historical origins and evolution of Halloween

Halloween, celebrated annually on October 31, has its origins in the ancient Celtic festival of Samhain. Approximately 2,000 years ago, British and Irish peoples observed Samhain to mark the end of summer and the beginning of the Celtic New Year. During this time, it was believed that spirits of the dead visited the living, leading people to wear costumes, light fires, and prepare food to appease or frighten these spirits.

The tradition evolved significantly following the Roman conquest of Celtic regions. Two Roman festivals merged with Samhain: Feralia, a period for honoring the dead through offerings at ancestral graves, and the festival of Pomona, dedicated to the Roman goddess of fruit and trees. The latter is linked to the modern tradition of ‘bobbing for apples.’

The name Halloween is derived from ‘All Hallows’ Eve,’ the night preceding All Saints' Day. Other modern customs also have deep historical roots, such as the Jack o’ lantern, which stems from Irish folklore, and ‘Trick or Treat,’ which evolved from British traditions where children offered prayers for souls in exchange for sweets.
