Halloween and candy are closely linked. Indeed, one of the most popular traditions of this holiday is to dress up and go knocking on neighborhood doors to collect treats. Candy has therefore become a key element of the Halloween experience, and children eagerly await this opportunity to fill their bags with sweets.
The origin of Halloween dates back to Celtic times, when the end of the year was celebrated during the Samhain festival, which took place on October 31st. It was believed that on that night, the spirits of the dead returned to Earth to haunt the living and cause mischief. To protect themselves, the Celts lit fires and dressed up as frightening creatures.
Over the centuries, this tradition evolved and combined with other holidays, notably the Christian All Saints' Day. The idea of asking for candy on Halloween appeared in the United States in the 1920s, when children began knocking on doors asking for sweets. This practice quickly spread throughout the country, and the phrase "Trick or Treat" became common.
The confectionery industry seized the opportunity of this tradition to develop new products and make significant profits. Today, candy has become one of the essential elements of Halloween, with millions of dollars in sales every year.
However, the commercial aspect of Halloween has been criticized by some, who believe that it has diverted attention from the original meaning of this holiday.
According to a study conducted by the National Confectioners Association in the United States, Halloween candy sales amounted to approximately $2.6 billion in 2020, despite the COVID-19 pandemic. Candy is therefore a significant source of revenue for the confectionery industry, and companies compete to offer innovative and attractive products for this occasion.
Nevertheless, Halloween remains a festive and joyful occasion for many people, with its scary costumes, terrifying decorations, and delicious sweets. The "Trick or Treat" tradition has become a fun ritual for children, who eagerly await filling their bags with candy and spending a memorable evening with their friends and family.
