The origin of trick-or-treating may have also come from Celtic tradition. Poor children in Britain and Ireland went door-to-door on All Hallows Eve and received food in exchange for the promise of playing for the giver’s dead relatives on All saints Day. This practice was know as “going –a- souling.” While that may be the start of it that traditional didn’t make its way to America. Here, trick-or-treating may have started with children trading songs for treats in the 1910s, according to the old newapaper texts.The tradition didn’t really take off until after World War ll, when popular children’s magazines started discussing it and the idea entered popular culture. Including radio show and cartoons.
