The holiday Halloween originated from ancient Celtic festivals, more specifically the festival of Samhain.

This festival was celebrated over 2,000 years ago. These festivals were celebrated in what is now called Ireland, the UK and Northern France.

The Celts had marked the end of harvest seasons and the beginning of the winter as a time associated with evil and death. The Celts believed that on October 31 the space between the living world and the spirit world became blurred, which allowed ghosts and spirits to return to the Earth.

The Celts would light bonfires and wear costumes made of animal heads and their skin in order to protect themselves. The festivals would also involve rituals to honor the dead and to try to seek guidance for the winter approaching. 

Today 2,000+ years later, we celebrate Halloween as a time to dress up, go trick or treating and even maybe pass out treats to the trick or treaters. We celebrate the fall and spooky season by attending pumpkin patches, haunted houses, decorating houses and even just enjoying fall foods and festivals.
