The Quick Answer
Trick-or-treating mixes old customs like 'souling' and 'guising' with a North American community tradition that grew popular in the 1930s–1950s.
The Story
In medieval Britain, people went 'souling' — offering prayers for the dead in exchange for small 'soul cakes.' In Scotland and Ireland, guisers performed for treats. In North America, communities promoted organized trick-or-treating to reduce Halloween pranks, and it became widespread after the Second World War.
Legend vs. History
The phrase 'trick or treat' appears in print in North America by the 1920s — the earliest known uses include Canadian newspapers.
