Halloween's      origins date back to the ancient Celtic festival of  Samhain,  It's an Iish Gaelic word and depending on where in Ireland it  can be pronounced as sow an, soow an, or sow en.
The Celts, who lived 2,000 years ago in the area that is now Ireland, the United Kingdom, and northern France, celebrated their new year on November 1. This day marked the end of summer and the harvest and the beginning of the dark, cold winter, a time of year that was often associated with human death.
Celts believed that on the night before the new year, the boundary between the worlds of the living and the dead became blurred. On the night of October 31, they celebrated Samhain, when it was believed that the ghosts of the dead returned to earth. In addition to causing trouble and damaging crops, Celts thought that the presence of the otherworldly spirits made it easier for the Druids, or Celtic priests, to make predictions about the future. For a people entirely dependent on the volatile natural world, these prophecies were an important source of comfort and direction during the long, dark winter.

To celebrate the event, Druids built huge  sacred      bonfires, where the people gathered to burn crops and  animals as sacrifices      to the Celtic deities.
During the celebration, the Celts wore costumes, typically consisting of animal heads and skins, and told each others fortunes. When the celebration ended, they re-lit their hearth fires, which they had extinguished earlier that evening, from the sacred bonfire to help protect them during the coming winter.

By A.D. 43, Romans had conquered  the majority of      Celtic territory. In the course of the four hundred  years that they ruled      the Celtic lands, two festivals of Roman  origin were combined with the traditional      Celtic celebration of  Samhain.
The first was Feralia, a day in  late October when      the Romans traditionally commemorated the passing  of the dead. The second      was a day to honor Pomona, the Roman  goddess of fruit and trees. The symbol      of Pomona is the apple and  the incorporation of this celebration into Samhain      probably  explains the tradition of "bobbing" for apples that is      practiced  today on Halloween.
By the 800s, the influence of  Christianity had      spread into Celtic lands. In the seventh century,  Pope Boniface IV designated      November 1 All Saints' Day, a time to  honor saints and martyrs. It is widely      believed today that the pope  was attempting to replace the Celtic festival      of the dead with a  related, but church-sanctioned holiday. The celebration      was also  called All-hallows or All-hallowmas (from Middle English Alholowmesse       meaning All Saints' Day) and the night before it, the night of  Samhain, began      to be called All-hallows Eve and, eventually,  Halloween. Even later, in A.D.      1000, the church would make November  2 All Souls' Day, a day to honor the      dead. It was celebrated  similarly to Samhain, with big bonfires, parades,      and dressing up  in costumes as saints, angels, and devils. Together, the three       celebrations, the eve of All Saints', All Saints', and All Souls', were  called      Hallowmas.
Modern Traditions
The American tradition of  "trick-or-treating"      probably dates back to the early All Souls' Day  parades in England. During      the festivities, poor citizens would  beg for food and families would give      them pastries called "soul  cakes" in return for their promise to      pray for the family's dead  relatives.
The distribution of soul cakes was  encouraged by      the church as a way to replace the ancient practice  of leaving food and wine      for roaming spirits. The practice, which  was referred to as "going a-souling"      was eventually taken up by  children who would visit the houses in their neighborhood      and be  given ale, food, and money.
The tradition of dressing in costume for Halloween      has both  European and Celtic roots. Hundreds of years ago, winter was an  uncertain      and frightening time. Food supplies often ran low and,  for the many people      afraid of the dark, the short days of winter  were full of constant worry.      On Halloween, when it was believed  that ghosts came back to the earthly world,      people thought that  they would encounter ghosts if they left their homes.      To avoid  being recognized by these ghosts, people would wear masks when they       left their homes after dark so that the ghosts would mistake them for  fellow      spirits. On Halloween, to keep ghosts away from their  houses, people would      place bowls of food outside their homes to  appease the ghosts and prevent      them from attempting to enter.
