The word "Halloween" means "hallowed evening" or "holy evening". It comes from a Scottish term for All Hallows' Eve which is the evening before All Hallows' Day.
Although some people have detected its origin in some Roman feasts, it is usually linked to the Celtic festival of Samhain which comes from the old Irish for the end of summer. It was celebrated in Ireland, Scotland and the Isle of Man. On the same date, Brittonic Celts in Wales and Brittany celebrated similar festivals. This date marked the end of summer and the beginning of winter. After, it was influenced by Christian tradition.
Regarding to USA, it was not until mass Irish and Scottish inmigration in the XIX century when Halloween became an important celebration in the country.
Death, evil and mythical monsters are themes included in Halloween imagery. The elements of the autumn season such as pumpkins and scarecrows with black, orange and purple colours are traditionally used in Halloween.
