Halloween (Allhallows Even) is the evening of October 31. In its strictly religious aspect, this occasion is known as the vigil of Hallowmas or , November 1, observed by the Roman Catholic and Anglican churches. In the fourth decade of the 8th century, Pope Gregory III moved this holiday to the present date (from May 13) for celebrating the feast when he consecrated a chapel in St. Peter’s Basilica in Rome to all the saints. Later, Gregory IV extended the feast to the entire church in 834. In Latin countries in Europe the evening of October 31 is observed mainly as a religious occasion, but in Great Britain, Ireland, and the United States, ancient Halloween folk customs persist alongside the ecclesiastical observance.

Halloween is the most popular holiday in the U.S. after Christmas, at least according to retailers — but it is the in terms of candy sales. Not only are candy and costumes popular purchases, but increasingly, houses are being decorated with “Halloween lights.” Parties are popular and are increasingly being celebrated the weekend . In Boston, for example, Salem is a popular location for these with its month-long Haunted Happenings celebrations — due to the Salem Witch Trials of 1692 — and the Massachusetts Turnpike traffic signs point out that Salem can be reached from Boston via Route 1A North. In Tokyo, I’ve seen young people dress up in western-style costumes during Halloween, especially in the district along the shopping area on.

Students of folklore believe that the popular customs of Halloween show traces of the Roman harvest festival of Pomona and of Celtic Druidism. These influences are inferred from the use of nuts and apples as traditional Halloween foods and from the figures of witches, black cats, and skeletons commonly associated with the occasion.

Pre-Christian Europe

In pre-Christian Ireland and Scotland, the Celtic year ended on October 31, the eve of Samhain, and was celebrated with both religious and harvest rites. For the Druids, Samhain (pronounced: SOWin) was both the “end of summer” and a festival of the dead. The spirits of the departed were believed to visit their kinsmen in search of warmth and good cheer as winter approached. It was also an occasion when fairies, witches, and goblins terrified the populace. The agents of the supernatural were alleged to steal infants, destroy crops, and kill farm animals. Bonfires were lighted on hilltops on the eve of Samhain. The fires may have been lighted in the belief of guiding the spirits of the dead to the homes of their kinsmen or to ward off witches. In the City Center of modern-day Dublin, one can find signs advertising “Samhain Halloween” parties. Samhain is also the name for in the modern Scots and Irish Gaelic languages.

Medieval Europe

During the Middle Ages when the common folk believed that witchcraft was devoted to the worship of Satan, this practice included periodic meetings, known as Witches’ Sabbaths, which were allegedly given over to feasting and revelry. One of the most important Sabbaths was held on Halloween. Witches were alleged to fly to these meetings on broomsticks, accompanied by black cats who were their constant companions. Stories of these Sabbaths are the source of much folklore about Halloween.

Colonial America

In 17th century Puritan New England the celebration of Halloween was banned, along with any special celebration of Christmas and Easter, though Catholic Maryland and Anglican Virginia retained some Halloween customs. During 19th century Victorian times, Halloween was generally tame and devoid of occult overtones. Instead of pulling pranks or haunting neighborhoods, young people chatted and flirted in festooned parlors.

Modern Practices

By the early part of the 20th century, Halloween became almost a civic affair with block parties and parades. Pranks and mischief were common on Halloween. Wandering groups of celebrants blocked doors of houses with carts, carried away gates and plows, tapped on windows, threw vegetables at doors, and covered chimneys with turf so that smoke could not escape. In some places, boys and girls dressed in clothing of the opposite sex and, wearing masks, visited neighbors to play tricks. These activities generally resembled the harmful and mischievous behavior attributed to witches, fairies, and goblins.

Trick or Treat

The contemporary “trick or treat” custom resembles an ancient Irish practice associated with . Groups of peasants went from house to house demanding food and other gifts in preparation for the evening’s festivities. Prosperity was assured for liberal donors and threats were made against stingy ones. These contributions were often demanded in the name of Muck Olla, an early Druid deity, or of , “dove of the Church” (also known as St. Colomba) who was an Irish missionary to Scotland during the 6th century. In England, some of the folk attributes of Halloween were assimilated by Guy Fawkes day celebrated on November 5. Consequently, Halloween lost some of its importance there.


In the late 20th and early 21st centuries became popular in larger parts of Mexico than just the central and south parts of the country, migrating to the north, and in parts of the US with Mexican immigrants. “The Day of the Dead” honored the dead, especially children, and harkens back to pre-Columbian indigenous traditions across Mexico and some parts of Latin America, Spain, Italy, and the Philippines.


Immigrants from Great Britain and Ireland brought secular Halloween customs to the U.S., but the festival did not become popular in America until the latter part of the 19th century. This may have been because it had long been popular with the Irish, who migrated here in large numbers after 1840. In America, although some churches observe Halloween with religious services, many people regard it as a secular festival. Other Protestant churches celebrate it as Reformation Day in commemoration of the date of October 31 in 1517 when Martin Luther nailed the 95 Theses to the northern wooden door of the Castle Church in Wittenberg, Germany.
