Halloween From Ancient Celtic Tradition to Global Phenomenon
Every October 31, streets, homes, and businesses are transformed with orange lights, ghostly figures, pumpkins, and costumes of all kinds. Millions of people around the world celebrate Halloween, a holiday that combines entertainment, traditions, and growing commercial activity. But behind this festive atmosphere lies a long and complex history, connected to ancient beliefs about the dead, spirits, and the arrival of winter.
The origins of Halloween are linked to Samhain, an ancient celebration observed by Celtic peoples in Europe that marked the end of the harvest and the transition into winter. For these communities, the changing of the seasons held special significance, as it was believed that during this time, the boundary between the world of the living and the dead became thinner. According to traditional beliefs, spirits could walk the Earth alongside other supernatural creatures, such as fairies and demons. Bonfires were lit, and costumes, possibly made from animal skins, were worn to frighten away or confuse wandering spirits. With the spread of Christianity throughout Europe, these ancient customs began to coexist with new religious observances, particularly All Saints' Day on November 1. The evening before eventually became known as All Hallows' Eve, the expression from which the name Halloween originated.
Migration brought these traditions to North America, particularly during the 19th century, when large numbers of Irish and Scottish immigrants introduced their customs to the United States and Canada. The Great Irish Famine, which began in 1845, triggered a major wave of immigration that helped popularize the celebration. Among the traditions brought to North America was the practice of carving figures to ward off evil spirits, inspired by the legend of Stingy Jack, a character condemned to wander through darkness carrying a light. In Ireland, turnips were traditionally used, but in North America, pumpkins became the preferred choice because they were more abundant and easier to carve. This gave rise to the familiar jack-o'-lanterns, hollowed-out pumpkins with illuminated faces that remain one of Halloween's most recognizable symbols.
Over time, Halloween evolved from a celebration primarily associated with religious and folk beliefs into a community event. In 1920, the city of Anoka, Minnesota, organized one of the first major Halloween parades in the United States, a tradition that continues today. During the 20th century, trick-or-treating also became increasingly popular, with children going door to door in costume to collect candy. This custom has roots in older European practices in which people requested food in exchange for prayers, songs, or small performances. Film and television, particularly horror movies, also helped establish the holiday's distinctive imagery, featuring witches, ghosts, monsters, and other characters that are now an essential part of Halloween celebrations.
Today, Halloween is both a cultural event and a major commercial occasion. In the United States, the National Retail Federation (NRF) estimates that consumer spending will reach $13.5 billion in 2026, compared with the $13.1 billion projected for 2025. According to its annual survey, 74% of consumers plan to celebrate Halloween, with participants expected to spend an average of $115.14 per person. Costumes account for approximately $4.4 billion, decorations for $4.3 billion, and candy for $4.1 billion. Even pets have become part of this growing industry, with an estimated $920 million expected to be spent on animal costumes. These figures illustrate how an ancient tradition has developed into an important commercial season for retailers, manufacturers, and entertainment companies.
Halloween's commercial expansion is also evident in other countries, although spending remains considerably lower. In the United Kingdom, a study by the agency Savvy estimates that consumers will spend approximately £705 million on Halloween in 2026, driven by purchases of candy, costumes, decorations, and party supplies. In Germany, the German Retail Association (HDE) estimated that additional Halloween-related sales would reach €520 million in 2025, representing a 63% increase compared with 2019. Although these studies use different methodologies and cover different periods, they demonstrate that Halloween has also become a commercial opportunity outside North America, particularly for the food, decoration, and entertainment industries.
However, Halloween celebrations vary considerably according to local customs. In Canada, families decorate their homes, and children go trick-or-treating through neighborhoods, much as they do in the United States. In Ireland, where some of the holiday's historical roots can be found, bonfires, festivals, and community celebrations remain part of the tradition. In the United Kingdom, costume parties, school activities, and children's trick-or-treating are common. In Mexico and other Latin American countries, Halloween coincides with traditional observances honoring the dead, such as Día de Muertos, or Day of the Dead, although the two celebrations have different origins, meanings, and customs. In countries throughout Europe and Asia, Halloween has also gained popularity through themed parties, commercial events, and entertainment activities, adapting to the cultural preferences of each location.
Although Halloween's growing consumerism has drawn criticism in some circles, the holiday is also valued for its social and recreational character. For one night, children and adults can take on fictional identities, enjoy family activities, and participate in community celebrations. Costumes, candy, pumpkins, and decorations have become central elements of an industry that generates billions of dollars, while the ancient beliefs that inspired the holiday remain visible in its symbols and traditions. In this way, Halloween continues to evolve, connecting its historical past with new forms of entertainment and celebration around the world.
