You can thank early residents of the United Kingdom for the trick-or-treating tradition. The earliest origins are traced to the Celtic Samhain, where people disguised themselves and had big bonfires to scare off the gods who were seeking to trick them. That pagan holiday eventually combined with the Christian All Soul's Day. That led to some new traditions such as guising, mumming, or souling, which still involved disguises and also included visiting neighbors for treats or entertainmen
