Every 31 October, houses glow with carved pumpkins, people dress as ghosts and monsters, and children head into the night in search of treats. The modern celebration feels instantly recognisable, but its history is far more complicated than a single origin story.
Halloween developed over a long period from a mixture of seasonal customs, Christian observances, folk traditions and, eventually, popular entertainment. Some practices disappeared. Others crossed oceans, changed shape and returned in forms their earlier participants might barely recognise.
Before Halloween
Long before the modern Halloween celebration existed, communities across Europe marked the changing seasons in different ways. Autumn meant shorter days, colder nights and the end of the main growing season.
In Ireland and parts of Britain, the Gaelic festival Samhain marked a seasonal transition around the beginning of November. Historical and later folkloric sources connect the period with gatherings, fires, feasting and supernatural beliefs.
Samhain is frequently described today as simply being the ancient version of Halloween. The real history is less straightforward. Scholars have debated exactly how particular Samhain customs relate to later Halloween practices, and Halloween also developed within a Christian calendar that became established over subsequent centuries.
It is safer to think of Halloween as a tradition that developed from several historical streams rather than as a holiday invented at one particular time or place.
All Hallows' Eve
The name Halloween comes from All Hallows' Eve — the evening before All Saints' Day on 1 November.
“Hallow” is an older word associated with a holy person or saint. Over time, “All Hallows' Evening” was shortened into forms including Hallowe'en and eventually Halloween.
All Saints' Day was followed by All Souls' Day on 2 November, traditionally associated with remembrance and prayer for the dead. Together these observances placed death, remembrance and the departed close to the seasonal celebrations occurring at the beginning of November.
Souling and Guising
Long before plastic buckets and supermarket costumes, there were European traditions involving people travelling from house to house.
One was souling. In forms recorded in Britain and Ireland, people went from door to door and received food — including small cakes — in connection with prayers for the dead.
Another tradition was guising, particularly associated with Scotland and Ireland. Participants disguised themselves and might perform a song, rhyme, joke or other small entertainment in exchange for food, coins or another reward.
These customs were not identical to modern trick-or-treating, but the resemblance is easy to see: costumes, houses, performances and a reward at the door.
Lanterns Before Pumpkins
One of Halloween's most famous symbols originally looked rather different.
In Britain and Ireland, people carved lanterns from root vegetables, particularly turnips. Faces could be cut into the vegetable and a light placed inside.
Some surviving carved turnip lanterns look considerably more sinister than the cheerful orange pumpkins familiar today.
As Halloween traditions developed in North America, pumpkins became the ideal replacement. They were larger, easier to hollow out and provided a much bigger surface for carving.
Eventually the glowing pumpkin became one of the most recognisable symbols of Halloween anywhere in the world.
Halloween Crosses the Atlantic
Immigration carried customs from Ireland, Scotland and elsewhere in Europe to North America. There, traditions mixed with local practices and continued to evolve.
By the nineteenth and early twentieth centuries, Halloween parties, games, costumes and neighbourhood celebrations were increasingly visible in the United States and Canada.
During the twentieth century, door-to-door trick-or-treating became a major part of the North American celebration.
Film, television, advertising and popular culture then helped export the imagery of pumpkins, witches, haunted houses and costumed trick-or-treaters around the world.
Ghost Stories and the Supernatural
Halloween has long been a natural home for stories about ghosts, witches and unexplained things in the darkness.
Autumn itself provides the perfect atmosphere: nights arrive earlier, trees become bare, fog appears and people spend more time gathered indoors.
Storytelling traditions surrounding winter and the supernatural were not limited to Halloween. Ghost stories have also been strongly associated with Christmas and other winter gatherings.
Halloween, however, gradually became the night most closely identified with the eerie and supernatural in modern popular culture.
From Homemade Costumes to Halloween Industry
For much of Halloween's history, costumes were improvised from whatever people already owned. Old clothes, sheets, homemade masks and simple disguises could transform someone into a ghost, witch or mysterious figure for the evening.
During the twentieth century, commercially produced costumes became increasingly common. Halloween expanded into a major seasonal event involving decorations, sweets, films, parties, attractions and elaborate costumes.
Yet the simplest version survives remarkably well. Turn off the lights, carve a face into something, tell a frightening story and suddenly a tradition centuries in the making feels very familiar.
A Very Short Halloween Timeline
Early seasonal traditions
Communities mark the transition into winter with gatherings, food, fires and traditions that sometimes include supernatural themes.
Medieval period
All Saints' and All Souls' observances become established, while customs involving remembrance, disguise and door-to-door activity develop in different regions.
18th–19th centuries
Halloween customs including guising, games and carved vegetable lanterns are recorded in Britain and Ireland.
19th century
Immigrants carry traditions to North America, where Halloween continues to evolve.
20th century
Costumes, parties and trick-or-treating become central features of the increasingly popular North American Halloween.
Today
Halloween is celebrated internationally through a mixture of old customs, modern entertainment and local traditions.
Halloween Keeps Changing
Halloween has never been frozen in time.
A carved turnip became a pumpkin. Regional disguising traditions contributed to a culture of elaborate costumes. Door-to-door customs developed into trick-or-treating. Folk tales became books, films, television programmes and haunted attractions.
That constant reinvention may be one reason Halloween has survived so successfully. Every generation inherits pieces of the celebration and adds something of its own.
Halloween's history is full of traditions that changed, disappeared or were reinvented. Elsewhere in the GhostlyTV Halloween archive, we'll explore the stories behind trick-or-treating, jack-o'-lanterns and some customs that have almost vanished.
