This holiday is celebrated on October 31, and you can see children knocking on doors, shouting "trick or treat!" However, as you may have already noticed, there is much history behind the holiday of Halloween, so let us get into details what this day is all about.

Halloween goes back to the ancient times of Celtic tribes, which celebrated a holiday called Samhain: a day that signifies the end of summer and harvest gathering. It was celebrated because dark and cold days were coming, and Celts believed that dark forces were growing in power, so it was necessary to celebrate the last warm and shiny days before the hard months of winter.

Celtic druids were believed to be spiritual leaders of their tribes, so they were responsible for the establishment of the connection with the ghosts of their dead ancestors. They believed that ghosts were coming with large bonfires in order to light their way in darkness. Thus, Celtic families tried to spread the bonfire from one to another in order to preserve themselves from evil powers.

At the beginning of the 5th century, Roman legions invaded the territories inhabited by Celtic tribes, so Samhain transformed into a day devoted to the change of seasons. This custom, though, was not stable for long, as long as the adoption of Christianity changed Samhain into the day of All the Hallows, or All-Hallows Eve. As a result, a mixture of Celtic, Roman, and Christian cultures created a unique holiday, when people pay tribute to all the saints, treat ghost and evil spirits to stay away from them, and use pumpkins lights as Celtic bonfires to attract the spirits of their dead ancestors. In spite of the fact that Halloween is commonly perceived as a holiday, which presupposes having fun, it is also a day when we need to pay a respect to our ancestors and enjoy last warm days.
