Where Did the Halloween Tradition Originate?

The Halloween tradition came from a group of people called the 'Celts" who lived in Europe almost 2000 years ago. They thought the dead would visit them on October 31st so they dressed up as spirits and ghosts so the dead would not harm them. Other countries took different interpretations on the Halloween idea, and decided that on November 1st they would remember the dead. So the people decided to call October 31st 'All Hallows Eve". In Ireland and Scotland, people dressed up and carried lanterns made from turnips on Halloween. Later in times, people gave food to the poor. This is where the term "trick-or-treating" came from.
