Why We Carve Pumpkins, Wear Masks and Knock on Strangers' Doors
Every Halloween custom gets an origin story attached to it, usually delivered with great confidence. Some of those stories hold up. Others were made up by Victorian folklorists who wanted everything to be older and more pagan than it was.
Here is what can actually be traced, tradition by tradition, with the uncertain parts marked as uncertain.
Carved lanterns
Well documented. In Ireland and Scotland people hollowed turnips and mangelwurzels, cut faces into them, and set an ember or candle inside. They were carried, set on walls, and used to startle.
What they were for
Sources give two overlapping purposes: warding off whatever might be moving on a night when the boundary was thought thin, and simple mischief. Both can be true. A carved turnip lit from within is genuinely unsettling, far more so than a pumpkin, because the flesh is dense and the face comes out cramped and sunken.
The Stingy Jack story
The Irish tale of a man who tricks the devil, is refused by both heaven and hell, and wanders with a coal in a hollowed turnip is real folklore. Whether it explains the custom or was attached to it later is not something the record settles.
Costumes and masks
Bring the season into the house
Guising is attested across Scotland and Ireland: going out disguised, performing a song or verse, receiving food or coin. The performance mattered. You did not simply hold out a bag.
The protective explanation
The common claim is that people disguised themselves so wandering spirits would mistake them for their own. This appears in folklore collections but the collectors were often writing centuries after any practice began, and asking leading questions. Treat it as plausible rather than established.
What changed in America
The performance requirement quietly dropped out during the twentieth century. Mass-produced costumes arrived in the 1930s. The move from home-made disguise to bought character costume is the single largest change in how the night looks.
Trick or treat
The phrase is North American and recent, appearing in print in the 1920s and 1930s. It fused the older door-to-door custom with a genuine local problem: Halloween mischief in American cities had escalated badly, and organised treat-giving was promoted partly to redirect it.
Sugar rationing interrupted the spread during the war. The post-war suburbs finished the job.
Apple bobbing
More for the season
Attested at autumn gatherings in Britain and Ireland, frequently as a divination game rather than a children's amusement. The first to catch an apple would be first to marry, and variants involved peeling an apple in one strip and reading the shape of the peel.
The Roman connection
You will read that this descends from the Roman festival of Pomona, goddess of orchards. The link is asserted far more often than it is evidenced. Apples were simply what was ripe and abundant in October across northern Europe, which is a sufficient explanation on its own.
More on the divination side in our piece on Samhain divination practices.
Black cats
The association is medieval and European, tied to witch trial material in which a witch was said to keep animal companions. Cats were common, nocturnal, independent, and lived close to households, which made them convenient to accuse.
The shelter myth
A modern belief holds that shelters suspend black cat adoptions each October because of ritual harm. Investigations by welfare organisations have repeatedly failed to find evidence of any such pattern. Some shelters do pause adoptions in October, but the stated reason is usually impulse adoption around costume season, not cruelty.
The older superstitions are genuinely regional and often contradictory, which we cover in black cat superstitions around the world.
Candles in windows
A quieter custom, and one that survived in Irish practice: a light left burning to guide the household's own dead home, and a place set or food left out for them.
This one has a clear line to All Souls' and to the wider European practice of feeding the dead. It also sits behind the modern dumb supper, a silent meal with a place laid for the absent.
Bonfires
Well attested in Ireland, Scotland, Wales and the Isle of Man. Communal fires were lit, hearths sometimes extinguished and rekindled from the shared flame, and cattle driven between fires or around them.
The practical layer is real: this was slaughter season, and fire had a role in preserving and in managing herds. The symbolic layer and the practical layer are not in competition.
What to do with all this
If you mark the season, knowing which parts are old and which are Edwardian invention does not spoil anything. It usually improves it. A custom you have chosen deliberately, understanding where it came from, tends to hold more weight than one you inherited by assumption.
And several of these are worth reviving on their own terms. The candle in the window costs nothing. The apple peel is a better party game than most. Setting an extra place is a genuinely moving thing to do.
Two more that get less attention
Mirrors and divination
A cluster of customs used the night for looking forward rather than back: a girl combing her hair before a mirror at midnight to see a future husband, apple peels thrown over a shoulder, nuts set on a hearth to see which burned steadily. These appear widely in nineteenth-century collections and were treated as party entertainment as much as prophecy.
The through-line is that a night when the boundary was thought thin was also considered a good night to ask questions. Our guide to Samhain divination goes into the individual methods.
The empty chair
Setting a place for the dead is attested across Europe in various forms, and it is the quietest custom on this list. No costume, no sweets, no performance. A plate, a chair, and an acknowledgement. The dumb supper is its most structured surviving version.
What the Victorians did to all of this
A great deal of what circulates as ancient Halloween lore was written down between roughly 1850 and 1910 by antiquarians who were, to put it gently, enthusiastic. They collected genuine material and then supplied explanations for it, and the explanations were shaped by what was fashionable to believe about druids at the time.
How to spot it
Watch for explanations that are too neat. Real folklore is regional, contradictory and often has no stated reason at all. When a custom comes with a single tidy purpose that resolves everything, it is usually a later addition.
Why it still matters
Not because accuracy is morally superior, but because the invented layer tends to crowd out the real one, and the real one is more interesting. The turnip lantern is genuinely stranger than the story attached to it.
The fuller history is in where Halloween actually came from, and the wider calendar in why Samhain is treated as the pagan new year.
Bringing one back
If you want a single custom to adopt this year, the candle in the window is the strongest candidate. It costs nothing, it requires no explanation to anyone else, and it has a clear traceable line rather than an invented one. Light it at dusk on the thirty-first and put it out before bed.
The Samhain altar guide covers the fuller version, and the room-by-room decor checklist handles the rest of the house.

Frequently Asked Questions About Halloween Traditions
Why do people wear costumes on Halloween?
The traceable root is guising in Scotland and Ireland, where people went door to door in disguise and performed for food. The idea that disguise hid you from wandering spirits appears in folklore collections but is not firmly evidenced. Shop-bought character costumes are a twentieth-century development.
Is apple bobbing really Roman?
Probably not. The link to the Roman goddess Pomona is asserted much more often than it is supported. Apples were the fruit in season across northern Europe in October, and the game appears in British and Irish sources mainly as a marriage divination rather than as a Roman survival.
Do animal shelters really stop black cat adoptions in October?
Some do pause them, but not for the reason usually given. Welfare organisations investigating claims of ritual harm have repeatedly found no evidence of a pattern. Where pauses happen, the stated concern is impulsive adoption around costume season.
What strikes you, reading the older collections, is how much of this was aimed at young unmarried people and how much of it was about the future rather than the dead. The apple peel, the mirror, the nuts on the hearth, the first to catch an apple in the water: these are marriage divinations, played at parties, by people who were probably half laughing at them. The solemn ancestor-focused version of the night that most modern practice emphasises is real and is also only one strand, and it sat alongside a great deal of flirting, drinking and showing off. Both were the same evening.
