This was a Gaelic festival celebrated mainly in Ireland and Scotland.
However, similar festivals were held by other Celts – for example the festival of Calan Gaeaf (pronounced kalan-geyf) which was held by the ancient Briton
The festival of Samhain celebrates the end of the "lighter half" of the year and beginning of the "darker half", and is sometimes regarded as the "Celtic New Year".
The celebration has some elements of a festival of the dead. The ancient Celts believed that the border between this world and the Otherworld became thin on Samhain, allowing spirits (both harmless and harmful) to pass through.
The family's ancestors were honoured and invited home whilst harmful spirits were warded off. It is believed that the need to ward off harmful spirits led to the wearing of costumes and masks.
Their purpose was to disguise oneself as a harmful spirit and thus avoid harm. In Scotland the spirits were impersonated by young men dressed in white with masked, veiled or blackened faces.
Samhain was also a time to take stock of food supplies and slaughter livestock for winter stores. Bonfires played a large part in the festivities.
All other fires were doused and each home lit their hearth from the bonfire. The bones of slaughtered livestock were cast into its flames.
Sometimes two bonfires would be built side-by-side, and people and their livestock would walk between them as a cleansing ritual.
Another common practise was divination, which often involved the use of food and drink.
The name Halloween and many present-day traditions, derive from the Old English era.h/t wiki
