What culture added the to Halloween?

It's tricky to pinpoint one specific culture that "added" trick-or-treating to Halloween. It's more accurate to say that the practice evolved over time, drawing inspiration from various traditions:

Early Influences:

* Celtic/Pagan: The ancient Celtic festival of Samhain, celebrated on October 31st, involved bonfires, feasts, and the belief that the veil between the worlds of the living and the dead was thin. This might have contributed to the practice of going door-to-door to beg for food or offerings, perhaps as a way to appease spirits.

* Medieval Europe: The practice of "souling" involved children going door-to-door on All Souls' Day (November 2nd) and singing prayers for the dead in exchange for food or money.

Later Influences:

* 19th Century: The practice of "guising" or "mumming" - dressing up in costumes and going door-to-door to perform pranks or songs - was common in Scotland and Ireland. This practice likely contributed to the modern-day Halloween tradition of trick-or-treating.

* Early 20th Century: In America, the practice of "going door-to-door" for treats on Halloween started to gain popularity, especially in the 1930s and 1940s. This was likely influenced by the combination of earlier traditions and the growing popularity of Halloween celebrations.

In Conclusion:

While trick-or-treating has its roots in various ancient and medieval traditions, it was a combination of factors, particularly in the early 20th century, that led to the practice becoming a widely recognized aspect of Halloween in America.
