The tradition of trick-or-treating dates back to ancient Celtic festivals, where people would light bonfires and wear costumes to ward off ghosts. However, the modern concept of Halloween candy began to take shape in the early 20th century. During the 1920s and 1930s, candy manufacturers began creating special treats for Halloween. The first packaged candy, such as Tootsie Rolls and candy corn, became popular, paving the way for the candy bonanza we know today. 💡
