Halloween was a popular pagan festival of the dead (Samhain). The ancient Celts believed that the souls of the dead returned to Earth the night before.
To change the festival the churches stated making All Saint Day on November 1st. This is the day when all of the saints are honored, especially those who did not have a day of their own. This day was formerly known as Allhallowmas, hallow meaning “holy” or “holy person.” All Saints Day is known in England as All Hallows Day. In that regard the evening before the day on 31st is called Alla Hallow Eve that originates the American word. Halloween.
Soul cakes, pan cakes, calcannon, apples and cider are the traditional foods for the day. Distributing candies to the dressed up kids is another very famous ritual around the world.
