About 2,000 years ago it is believed that Halloween originated in Ireland and spread with the flow of immigrants.

People would light bonfires and wear costumes to ward off roaming ghosts.

Eventually Halloween grew to be a community based event, with child friendly activities such as trick-or-treating and dressing up as various fictional characters, ghosts, goblins or celebrities.
