Halloween is one of the oldest holidays with origins going back thousands of years. The holiday we know as Halloween has had many influences from many cultures over the centuries. From the Roman's Pomona Day, to the Celtic festival of Samhain, to the Christian holidays of All Saints and All Souls Days.
Hundreds of years ago in what is now Great Britain and Northern France, lived the Celts. The Celts worshipped nature and had many gods, with the sun god as their favorite. It was "he" who commanded their work and their rest times, and who made the earth beautiful and the crops grow.

 The Celts celebrated their New Year on November 1st. It was celebrated every year with a festival and marked the end of the "season of the sun" and the beginning of "the season of darkness and cold."

The Celts believed, that during the winter, the sun god was taken prisoner by Samhain, the Lord of the Dead and Prince of Darkness. *

On the eve before their new year (October 31), it was believed that Samhain called together all the dead people. The dead would take different forms, with the bad spirits taking the form of animals. The most evil taking the form of cats. 

 On October 31st after the crops were all harvested and stored for the long winter the cooking fires in the homes would be extinguished. The Druids, the Celtic priests, would meet in the hilltop in the dark oak forest (oak trees were considered sacred). The Druids would light new fires and offer sacrifices of crops and animals. As they danced around the the fires, the season of the sun passed and the season of darkness would begin. 

When the morning arrived the Druids would give an ember from their fires to each family who would then take them home to start new cooking fires. These fires would keep the homes warm and free from evil spirits.
