Although many people associate Halloween with the United States, it actually originated in Ireland as a Celtic festival called Samhain, which marked the end of the harvest season and the beginning of the darker half of the year. On this night, it was believed that the spirits of the dead could cross over into the world of the living and cause mischief or harm. To ward off these supernatural beings, the Celts would light bonfires and wear costumes and masks. Later, when Christianity spread in Europe, Samhain was merged with the Christian holidays of All Saints’ Day and All Souls’ Day and became known as All Hallows’ Eve or Halloween.
