Where Did Halloween Come From?
It’s not exactly clear what ancient Celts did during Samhain, the pagan holiday we now link with Halloween, but historians have some idea thanks to a surviving bronze calendar. The first written mentions of Samhain appeared in Europe around the first century, marking winter’s swift approach and the start of the Celtic new year. Celebrated on October 31, Samhain was a time when the wall between the spirit plane and the living world was thought to be at its weakest, allowing spirits to cross the boundary with ease. In an effort to curb vandalism and mishaps from angsty ghosts, the Celts hosted welcoming bonfires and left food offerings; eventually, the practice transitioned to dressing as ghouls themselves and traveling door to door in search of refreshments and merriment. Modern Halloween has held tight to many Celtic traditions, like fortune-telling and bobbing for apples, but Roman Christian attempts to squash pagan ceremonies, starting around 600 CE, started the slow transition from religious festival to the spooky secular event.
Colonists in early America brought some Halloween traditions with them (telling ghost stories, pulling pranks, and sharing harvest meals) but strict social and religious rules in Puritan communities scaled back the death-centric influence of early celebrations. Halloween would gain back some of its edge around the mid-1800s when a large influx of Irish immigrants began sharing their holiday traditions passed down from Celtic ancestors, such as carving pumpkins and donning costumes. The Halloween we’re familiar with today slowly spread across the US, and by the 1920s, trick-or-treaters across the country were looking forward to their one night of socially acceptable mischief and candy collecting.
