Samhain is a big festival. 

Samhain is a Gaelic festival. 

In old stories, Samhain was a special time. People believed the boundary between worlds was thin. The spirits or 'aos sí' could visit. People set a place at the table for dead kin. They also gave food to the spirits. This helped ensure everyone survived the winter. Some people wore costumes. They did this to hide from the spirits. Others went door-to-door for food. They might recite verses to get treats.
Farmers also used this time to move cattle. They brought animals down from summer pastures. People lit big bonfires for protection. These old ways helped shape modern Halloween. Many American traditions come from these customs.
Samhain is a Gaelic festival that marks a big change in the year. 

During the festival, many different things would happen. Farmers brought their cattle down from summer pastures to the lowlands. They also slaughtered some of their livestock at this time. People lit large bonfires to help protect and cleanse the land. Some people practiced "guising," which means wearing costumes to go door-to-door. They would recite verses to neighbors in exchange for food. People also used fruits like apples and nuts for divination. This is a way to try to learn about the future.
History tells us that Samhain has very old roots. It is mentioned in early Irish literature from the 9th century. Some people believe it started with ancient Celtic pagan traditions. Even older stone tombs in Great Britain and Ireland align with the sunrise during Samhain. 
Many myths and legends are tied to this time of year. In Irish mythology, Samhain was a time when the boundary between worlds blurred. 
Today, we can see how Samhain changed over many centuries. In the 9th century, the Western Church chose November 1st for All Saints' Day. This likely happened because of the influence of Irish missionaries. Later, November 2nd became All Souls' Day. These traditions eventually influenced the modern holiday we call Halloween. Many American Halloween traditions actually came from Irish and Scottish immigrants. Even now, some people celebrate Samhain as a religious holiday.
Samhain is a major Gaelic seasonal festival marking the transition from autumn to winter. 
The festival functions as a threshold or liminal period. In Celtic belief, this means the boundary between the physical world and the Otherworld becomes blurred. 
Practical agricultural tasks also defined the Samhain season. As the weather turned, farmers moved cattle from summer pastures down to the lowlands. This period often involved the slaughtering of livestock for the winter months. Special bonfires were lit during the festival. These fires were believed to possess protective and cleansing powers for the community. Another tradition involved "mumming" or "guising." In this practice, people wore costumes and went door-to-door. They would recite verses in exchange for food. These costumes may have served to disguise people from the aos sí.
Samhain is deeply rooted in ancient history and mythology. The festival is mentioned in the earliest Irish literature dating back to the 9th century. Some evidence suggests even older origins in the Neolithic period. Certain passage tombs in Great Britain and Ireland are aligned with the sunrise during the Samhain season. 
Irish mythology is filled with stories centered on this time of year. The hero Fionn mac Cumhaill is a central figure in several Samhain tales. In one legend, he slays the fire-breather Aillen, who attacked the palace of Tara. In another, Fionn touches the Otherworld and gains great wisdom. Other myths describe supernatural beings like the Fomorians. These beings represented the destructive forces of nature, such as darkness and blight. Some ancient texts claim the people of Nemed had to provide tributes to these forces at the start of winter.
Historical shifts changed how Samhain was observed over time. In the 9th century, the Western Church established November 1st as All Saints' Day. This change may have been influenced by Irish missionaries. November 2nd later became All Souls' Day. These Christian observances and the older Samhain traditions likely influenced one another. This combination eventually shaped the modern holiday of Halloween. Many American Halloween customs were brought over by Irish and Scottish immigrants.
Today, Samhain maintains several different cultural connections. Many people recognize its influence through modern Halloween celebrations and divination practices. Divination often involved using items like apples and nuts to predict the future.
