Why Do Americans Carve Pumpkins? The Real Story of the Jack-o’-Lantern, From Irish Turnips to Your Porch

Every October, millions of Americans scoop out a pumpkin, cut a face into it, and set it glowing on the porch. It feels like a tradition that must be ancient, and in a way it is. But the pumpkin itself is the newest part of the story. The jack-o’-lantern began as a ghost story, travelled across the Atlantic inside a turnip, and only became a pumpkin once it reached America. Here is the full journey, from a bog light in Ireland to the carved masterpiece on your doorstep.

The Short Answer

A jack-o’-lantern is a hollowed-out vegetable with a carved face and a light inside, made to look like a glowing head. It comes from an Irish folk tale about a man named Stingy Jack, from the Celtic festival of Samhain, and from an old habit of carving vegetables into lanterns to ward off evil spirits. Irish immigrants brought the custom to America in the 1800s, swapped the turnip for the pumpkin, and turned a folk practice into the Halloween symbol we know today.

First, the Name: From Watchman to Bog Light

Long before anyone carved a pumpkin, the words «jack-o’-lantern» were already in use. In 1663, the term meant a night watchman, a man carrying a lantern on his rounds. Over time, people started using the same name for the strange lights sometimes seen over marshes and bogs at night, flickering flames that seemed to dance and disappear when you walked towards them.

Those lights had a scientific explanation: gases released by decomposing plant matter in wet ground can ignite and glow. Folklore gave them another: they were will-o’-the-wisps, or ignis fatuus in Latin, spirits trying to lead travellers astray. The name «jack-o’-lantern» stuck to those lights, and later to the carved lanterns said to look like them. The jack-o’-lantern was a ghost light before it was ever a vegetable.

The Legend of Stingy Jack

The story that gave the lantern its name is the legend of Stingy Jack, a clever, hard-drinking Irish blacksmith who, according to folklore, tricked the Devil not once but twice. In the first trick, Jack invited the Devil for a drink and persuaded him to turn himself into a coin to pay for it. Instead of paying, Jack slipped the coin into his pocket next to a silver cross, trapping the Devil. He only freed him after the Devil promised to leave him alone for a year.

In the second trick, Jack persuaded the Devil to climb a tree to pick fruit, then carved a cross into the bark so the Devil could not climb down. This time the price of freedom was a promise never to claim Jack’s soul. When Jack eventually died, the bargain backfired in a way he had not foreseen. Heaven would not take him because of his life, and Hell could not take him because of the Devil’s promise. So Jack was left to wander the earth in darkness, with only a burning coal inside a hollowed-out turnip to light his way. That wandering ghost became known as Jack of the Lantern, or jack-o’-lantern.

Historians note that the legend first appeared in print in the 19th century, which means it was told as a folk tale long before anyone wrote it down. It may not be literally true, but it explains why the lantern was seen as both a joke and a warning: a light that keeps wandering spirits away, and a reminder of a man who outsmarted himself.

Samhain and the Church Calendar

The lantern story sits inside a bigger festival. Samhain, pronounced «sow-in,» was the Celtic festival marking the end of the harvest and the start of winter. It was a time when, people believed, the boundary between the living and the dead grew thin, and spirits could cross over. People lit bonfires, wore disguises to avoid being recognised by wandering souls, and left food out for the dead.

When Christianity spread through Ireland and Britain, the Church placed All Saints’ Day on November 1, in the 8th century, and the evening before became All Hallows’ Eve, now Halloween. The old customs did not disappear; they blended with the new calendar. Disguises became costumes, offerings became treats, and carved lanterns became part of the night’s protection, meant to scare away exactly the kind of spirit Samhain was said to let loose.

From Turnips to Pumpkins: The American Switch

In Ireland and Scotland, people carved turnips. In England, they sometimes used beets. Turnips are hard, small, and difficult to carve, which is part of why the old lanterns had crude, frightening faces rather than the elaborate designs we see today. Potatoes and mangelwurzels, a kind of large beet, were also used. The point was not beauty; it was a glowing face in the dark.

That changed when Irish immigrants came to America in large numbers in the 19th century, especially during and after the Irish famine of the 1840s. They brought the lantern custom with them, and they found something better to carve: the pumpkin. Pumpkins were native to North America, widely grown, much larger than a turnip, softer to cut, and hollow inside. A pumpkin could hold a candle easily, and its orange skin glowed beautifully when lit. Within a generation, the pumpkin had replaced the turnip, and the custom had shifted from a general autumn practice to something tied specifically to Halloween.

Pumpkins were already part of American autumn life, through pie and harvest festivals, so the lantern did not feel foreign. That is why it took root so quickly: an old Irish idea inside a very American vegetable.

Pranks, Porches, and the 1892 Party

In 19th-century America, carved pumpkins were not only porch decorations. They were also prank props. Young people carried glowing pumpkins to frighten travellers on dark roads, and the faces grew cruder and stranger as the joke went on. In New England, there was a tradition of stealing pumpkins from fields and carving them, a mischief that farmers grumbled about but that helped spread the custom from town to town.

By the late 1800s, the carved pumpkin was becoming respectable as well as mischievous. A good marker is a Halloween party hosted by the mayor of Atlanta in 1892, where carved, lit pumpkins were used as decorations. The lantern had moved from the roadside to the parlour, and over the following decades it gained a new job: a lit pumpkin on the porch signalled to trick-or-treaters that a house welcomed visitors, a meaning it still carries today.

The 20th Century: How Carving Became Big Business

After the Second World War, Halloween changed. The baby boom meant more children, the end of sugar rationing meant more sweets, and trick-or-treating became a neighbourhood institution. Pumpkin growers and breeders responded by developing pumpkins specifically for carving, with names like Spooktacular, Happy Jack, and Jack-O-Lantern. These varieties were bred to be a good size, a good shape, and easy to cut, with sturdy walls that hold a face well.

Mass media did the rest. Postcards, magazines, films, and later television showed carved pumpkins as the visual shorthand for Halloween. A house without a pumpkin started to look like a house that had forgotten the holiday. By the late 20th century, carving was no longer a folk craft. It was a family activity, a school project, and a seasonal industry, with pumpkin patches, carving kits, and stencils sold in every supermarket in October. If you want the sweeter side of the same season, our story of how pumpkin spice took over America pairs well with this one.

How to Pick, Carve, and Keep a Pumpkin

A good jack-o’-lantern starts at the pumpkin patch. Choose a pumpkin with a firm stem, no soft spots, and a flat bottom so it sits steady. A pumpkin that feels heavy for its size has thick walls, which carve cleanly. For carving, look for a variety sold for that purpose, often labelled as a carving pumpkin, rather than a pie pumpkin, which is smaller and denser.

Carving safely matters more than carving cleverly. Cut from the bottom rather than the top if you can: a bottom hole makes it easier to set the pumpkin over a light, and it keeps the stem and top intact for a natural lid. Use a small serrated knife or a carving kit, not a large kitchen knife, and always cut away from your body. Children should draw the design and scoop the seeds while an adult does the cutting. For light, a battery-powered LED is safer than a candle, especially on a dry porch, and it will not blow out in the wind.

To make a pumpkin last longer, keep it out of direct sun and bring it inside on warm days, since heat speeds up rotting. Carve it as close to Halloween as you can, ideally a day or two before, rather than a week early. A pumpkin carved on October 30 will look far better on Halloween night than one carved on October 20, however good the design.

Carving Culture Today

Today, carving has gone far beyond the classic triangle eyes and toothy grin. Stencil books and online patterns let anyone carve a cat, a haunted house, a movie character, or a detailed portrait. Contests and festivals celebrate the best work, from small-town pumpkin festivals to large displays like the Great Jack O’Lantern Blaze in New York, where thousands of carved pumpkins light a trail. Some artists use power tools and shading techniques to create pumpkins that look more like sculptures than lanterns.

At the same time, the simple version has not gone away. Most porches still carry the classic face, cut by a child with a parent’s help, glowing for one night. The pumpkin changed, the tools changed, and the designs got fancier, but the idea is the same one that crossed the Atlantic in the 1800s: a light in the dark that says someone inside is ready to welcome you.
