Trick-or-treating as we know it today is believed to have originated in the United States in the early 20th century. It is thought to have been influenced by ancient Celtic traditions of leaving out offerings to appease spirits during Samhain, as well as the Christian practice of souling. The modern version of trick-or-treating, where children go door-to-door asking for candy, became popular in the 1930s and 1940s in America. While there isn't a single inventor of trick-or-treating, it evolved over time from various cultural practices and traditions. **
