HALLOWEEN IS a complicated mix of traditions. According to history.com, its traditions reach back to Samhain, an ancient Celtic festival during which people lit bonfires and wore costumes to ward off ghosts.

Another big influence is All Hallows’ Eve, the evening before All Saints Day (a day to honour all saints, set as November 1 in the eighth century by Pope Gregory II), which was later called Halloween.

Over time the evening became a day filled with trick-or-treating, carving jack-o’-lanterns, eating treats and wearing costumes.
