The modern holiday of Halloween evolved from a number of ancient traditions. Harvest festivals, solemn religious observance, remembrance of the dead, children's frolics, and anarchistic high jinks have distilled into a uniquely American holiday celebrated on October 31 with candy, costumes, and an increasing number of spine-chilling decorations.
Many historians believe that Halloween has its origins as early as the fifth century BCE in the Celtic festival of Samhain, which marked the end of harvest and acknowledged the thin line between life and death. Theories differ as to the meaning behind the disguises and pranks that became associated with the celebration, but some historians believe they were intended to confuse and distract the spirits of the dead thought to roam the world on Samhain. The Catholic Church, seeking to suppress indigenous religious practices, reinvented Samhain as All Saints' Day, which was established on November 1; the day before it became All Hallows Eve, or Hallowe'en.
