The scary, modern fun aspect of Halloween is seen today in Jack-o-lanterns, which are created by people carving frightening faces into pumpkins. Halloween has been celebrated for hundreds of years, and our modern-day traditions are very different from what our ancestors did back in the day. Many aspects of Halloween we celebrate today are American, with various European traditions mixed in with Native American ones over time. Todays Halloween customs are thought to be influenced by folk practices and beliefs of the Celtic-speaking countries, with some believed to have pagan roots. Halloween has roots in the Celtic festival of Samhain, which was celebrated mostly in present-day Ireland in the years immediately preceding the emergence of Christianity. The Celtic festival of Samhain was originally the day that Celts believed that the dead returned to earth, and that the priests of their society, the Druids, were most easily able to make predictions due to the presence of these spirits. In light of this belief, Celts used the Celtic festival of Samhain to make enormous bonfires for holy devotion, to dress up in animal-like clothing, and to tell one another their fortunes. Trick-or-treating may have originated as Celtic festivities for the Ancient Celtic festival. Halloween dates from the ancient Celtic festival called Samhain, celebrated throughout present-day Ireland, Scotland, and the United Kingdom, and parts of northern Europe. Halloween likely developed partly out of a pre-Christian festival called Samhain, celebrated around November 1st in Ireland during the Early Medieval period, marking the start of a new year. There is considerable evidence that the Celtic peoples of Western Europe before Christianity not only celebrated Samhain, they regarded it as a Celtic new year. In fact, Halloweens history dates back thousands of years to Celtic celebrations of Samhain, the holiday which marked the end of the harvest season and the start of a new year. What we today call Halloween was, in fact, an ancient festival. While traditions for the Gaelic holiday Samhain originated in Celtic countries, contemporary Wiccans make no attempt at historical replications of Samhain festivities. However, the holiday Halloween has its roots in the ancient Celtic festival Samhain , a pagan religious festival celebrating the arrival of the harvest at the end of the summer, where people would light bonfires and don costumes to keep ghosts away from harvesting. The origins of Halloween, and many Halloween practices, can be traced back to Samhain, the ancient pagan Celtic festival which is Gaelic for summer ends, the day on which we say goodbye to warmth and light. Halloween falls on Oct. 31) because the Pagan holiday called Samhain falls on this date. Halloween has its origins in the pre-Christian holiday of Samhain, which was celebrated by Celts of Ancient Britain and Ireland. Halloween was introduced by Christian authorities as an alternative to the old Samhain Festival . One theory holds that many Halloween traditions may have been influenced by the ancient Celtic harvest festivals, especially the Gaelic Samhain, which may have had pagan roots; some scholars believe Samhain may have been Christianized by the early church into All Hallows Day, alongside All Hallows Eve. The modern-day practice of Halloween in countries like the United States and Canada--where this tradition is more widespread--the U.S. Canada shares in this ancient tradition, although certain aspects of Halloween are relatively recent developments, which date to the Celtic Samhain festival. Halloween has changed over time, evolving from an ancient tradition into the brightly-coloured festival of fear that we know and love today. As it exists in America today, Halloween is the day when we all get to revel in the dark, creepy side of life, along with plenty of candy. Yes, those are things that we enjoy about Halloween, the holiday that we celebrate the last day of the month of October. The night before, on Oct. 31, is celebrated as Christian All Hallows Eve and then later as Halloween. November 1 was celebrated with a Mass, a bonfire, and people dressed in costumes while angels and saints paraded around the villages. November 2 was created as part of what is often considered to have been Christianitys attempt to expunge and replace the Celtic festival of Samhain, since that was celebrated with bonfires and costumes as well. The old festival is thought to have Celtic pagan origins, with evidence suggesting that it was celebrated as far back as antiquity. However, it was in fact the church itself which preserved the tradition of Samhain in the west, Christianizing it in the ninth century, setting the stage for converting northern European pagan religious traditions to the Christian Halloween celebration.
