The Celtic festival of Samhain, which was celebrated on November 1 in modern calendars, is where Halloween got its start.
People donned costumes and built bonfires to fend off ghosts since it was thought that on that day, the souls of the deceased made their way back to their homes. All Saints Day was established by Pope Boniface IV in the seventh century CE and was first observed on May 13.
Pope Gregory III changed the holiday's date to November 1 a century later, most likely as a Christian replacement for the pagan celebration of Samhain. All Hallows Eve, or Halloween, came to be recognized as the day before the holy holiday.
