A Brief History of Halloween

When was this event established: Halloween’s origins date back to the ancient Celtic festival of Samhain, celebrated from October 31 to November 1 to welcome the harvest and usher in “the dark half of the year.” Celebrants believed that the barriers between the physical world and the spirit world broke down during Samhain, allowing more interaction between humans and the Otherworld. Later, in the year 1000, early Christian leaders made November 1 All Souls’ Day, or All-Hallowmas, a day to connect to and honor the dead and martyrs. Today, it’s widely believed that the church was attempting to replace the Celtic festival with a related Christian holiday.

How has it developed since then: In the Middle Ages, various Halloween customs began to take shape, such as souling and jack-o-lanterns. The holiday was greatly expanded after it was brought to the US by Irish immigrants in the mid-19th century. Then, ideas like trick-or-treating and pulling pranks on Halloween emerged. In the early 20th century, Halloween slowly became a secular, community-centered holiday, with parades and town-wide parties, but also violent outbursts and vandalism. To keep boys from vandalizing communities, parents started organizing “haunted house visits.” After the 1950s, Halloween costumes and movies went mainstream, and the holiday became a widespread American tradition. 

3 Interesting Facts About Halloween

1. History of “treating”: Trick-or-treating stems from old customs: ancient Celts would “treat” deities with sacrifices to live in peace with them. They also prepared banquets with food to appease unwelcome spirits. Then, in the Middle Ages, people started dressing as ghosts, demons, and other dark creatures, performing antics in exchange for food and drink. In addition, poor people visited wealthier families and received soul cakes in exchange for praying for the souls of the homeowners’ dead relatives.
2. Scary pumpkins: Carving scary faces on vegetables has roots in Ireland, where large turnips were the early canvasses. The name “jack-o’-lantern” comes from an Irish folktale about a man named Stingy Jack who played various tricks on the Devil while alive. When Jack died, the Devil punished him by sending him to roam the Earth forever with only a lump of burning coal in a carved-out turnip to light his way. The legend says that people carved scary faces in vegetables to scare off Stingy Jack. 
3. Famous parties: One of the most notable Halloween gatherings in the US is the New York’s Village Halloween Parade. The event draws more than 2 million spectators and includes about 70,000 costumed marchers parading up Sixth Avenue. In addition, Chapel Hill in North Carolina has a downtown street party that can draw crowds of nearly 80,000 in a town with a population of just 54,000.
