Celtic Origin
Celtic: The ancient Celtic (Irish, Scottish, Welsh) festival called Samhain is considered by man to be a predecessor of our contemporary Halloween. Samhain was the New Year's Day of the Celts, celebrated on 1 November. It was also a day of the dead, a time when it was believed that the souls of those who had died during the year were allowed access to the land of the dead. It was related to the season: by Samhain, the crops should be harvested and animals brought in from the distant fields.
