Trick or Treating

Trick-or-treating or guising at Halloween may come from customs related to the Celtic festivals of Samhain and Calan Gaef or from customs related to the Christian holy days of All Saints  and All Souls. 

The tradition of guising — children disguised in costumes going from door to door for food and coins — is recorded in Scotland at Halloween in 1895, where masqueraders in disguise carrying lanterns made out of scooped out turnips, visit homes to be rewarded with cakes, fruit and money. Before the 20th century, guising at Samhain was done in parts of Ireland, Mann, the Scottish Highlands  and islands, and Wales. 

The activity is prevalent in the United States, Canada, United Kingdom, Republic of Ireland, Puerto Rico, and northwestern and central Mexico. 

In the latter, this practice is called calaverita (Spanish for "little skull"), and instead of "trick or treat", the children ask ¿me da mi calaverita? ("can you give me my little skull?"); where a calaverita is a small skull made of sugar or chocolate.
