How ghosts became part of Halloween

Samhain, an ancient Celtic festival, marked the end of the harvest season and the beginning of winter, symbolizing a transition into the new year. During Samhain, the Celts believed that the boundary between the living and the spirit world blurred, allowing spirits to walk the Earth.

Centuries later, as Christianity spread around the world, they introduced All Souls’ Day on November 2. This new observance preserved the idea of a time when the living and the dead could connect, linking it with the seasonal tradition of Samhain and blending it with Christian customs.
