The History of Samhain: Where Halloween Begins

Long before pumpkins glowed on porches and children went door to door asking for candy, the end of October marked a very different kind of threshold.

The harvest was ending. The days were growing shorter. Winter was approaching.

And in Gaelic-speaking parts of Ireland and Scotland, this seasonal turning was marked by Samhain.

Today, Samhain is often described as an ancient Celtic festival and as the origin of Halloween. There is truth in that connection, but the real history is a little more complicated, and honestly, a lot more interesting.

What Was Samhain?

Samhain, generally pronounced something like sow-in, was a major seasonal festival in Gaelic culture. It marked the beginning of winter and was traditionally associated with November 1, with many celebrations taking place on the evening before.

For communities whose lives depended heavily on agriculture and livestock, this was an important turning point in the year.

The harvest had been gathered. Animals were brought in from summer pastures, with livestock that could not be kept through winter often slaughtered. The bright, productive part of the year was giving way to the cold and darkness of winter.

Samhain was therefore a time of transition.

And transitions have always carried a little mystery with them.

A Time When the Worlds Drew Close

One of the most enduring ideas associated with Samhain is that the boundary between the human world and the Otherworld became less secure.

Medieval Irish literature contains stories in which supernatural beings and humans interact at Samhain. The University College Cork Department of Early and Medieval Irish describes Samain as a time when the natural and supernatural worlds were believed to come particularly close together, allowing mortals and inhabitants of the Otherworld to encounter one another.

This wasn't necessarily a simple celebration of ghosts.

The Otherworld in Irish tradition was populated by powerful and sometimes dangerous beings, and encountering them could bring knowledge, fortune, danger, or transformation.

Samhain was a liminal time, and liminal times have a way of making ordinary rules feel less certain.

Fire, Food, and Community

Fire was an important part of Samhain traditions.

Bonfires were associated with the festival, and communities gathered around them for feasting and celebration. Later Irish and Ulster traditions preserved memories of fires, masks, storytelling, food, and communal gatherings around Samhain Eve.

And this is something that can sometimes get lost when we talk about Samhain today.

It wasn't simply a night of fear.

It was also a social festival.

People gathered together as the year changed around them. They ate, told stories, played games, and participated in seasonal customs. The Ulster Folk Museum describes Samhain and later All Hallows' Eve traditions as occasions for community, shared stories, warmth, and laughter as winter approached.

There is something wonderfully human about that.

When the nights get longer, we gather around the fire.

When winter approaches, we share food.

When the darkness feels bigger, we tell stories.

Divination and the Future

Samhain was also associated with divination.

Medieval Irish sources connect the festival with supernatural knowledge and attempts to discover what the coming year might bring. One account recorded in the Annals of Tigernach for 1084 describes a man visiting Newgrange at Samain to seek knowledge of the future.

Later Irish Halloween traditions continued this fascination with divination.

Foods such as barmbrack could contain hidden objects whose meanings were used to foretell aspects of a person's future. Other traditions involved games and rituals intended to reveal information about marriage, prosperity, or fortune.

That makes some of our modern Halloween games look a little less random.

The desire to ask, What comes next? is much older than Halloween itself.

What About Costumes and Spirits?

This is where things get particularly interesting.

You may have heard that ancient Celts dressed in animal skins and disguises at Samhain to trick or frighten spirits.

That idea is widely repeated, but the historical evidence is not nearly as straightforward as popular Halloween histories sometimes suggest.

What we can document much more clearly is that later Irish and Scottish Halloween traditions included disguises, masks, “guising,” pranks, and supernatural beliefs. The Ulster Folk Museum's historical collections, for example, document the use of masks or “false faces,” mischief, storytelling, and protective customs around Halloween.

So while the modern Halloween costume has connections to older traditions, we shouldn't assume that every costume custom practiced today can be traced directly to an ancient Samhain ritual.

History is rarely that neat.

From Samhain to All Hallows' Eve

As Christianity spread through Ireland and other parts of Europe, existing seasonal traditions continued to evolve.

November 1 became All Saints' Day, also known as All Hallows' Day. The evening before became All Hallows' Eve, which eventually became Halloween. November 2 became All Souls' Day, a day associated with remembering the dead.

Over centuries, Christian observances and older seasonal customs existed alongside one another and influenced the traditions that developed around this time of year.

That's why modern Halloween contains such a fascinating mixture of influences.

Ancient seasonal traditions.

Christian observances.

Medieval folklore.

Irish and Scottish folk customs.

Immigrant traditions.

And eventually, distinctly American Halloween traditions.

The Turnip Came Before the Pumpkin

Here's one of my favorite pieces of Halloween history:

The jack-o'-lantern wasn't originally a pumpkin.

In Ireland and other parts of the British Isles, turnips and other root vegetables were carved into lanterns. Historical traditions associated these lanterns with frightening or warding off supernatural beings.

When Irish immigrants brought Halloween traditions to North America, the pumpkin became the preferred carving material.

And honestly, it makes sense.

Have you ever tried carving a turnip?

The pumpkin definitely won that particular evolutionary battle.

So, Was Samhain the First Halloween?

Not exactly.

Halloween has roots in Samhain, but saying that Halloween is simply “Samhain with a different name” erases centuries of cultural change.

Likewise, calling every modern Halloween custom an ancient Samhain practice isn't supported by the historical evidence.

The connection is real, but it is a long chain rather than a straight line.

Samhain influenced the seasonal traditions that developed around this time of year. Christian observances became part of the calendar. Irish and Scottish folk customs continued to evolve. Immigrants carried traditions across the Atlantic. And American culture transformed Halloween into the holiday many of us recognize today.

The result is something that doesn't belong entirely to one period or one tradition.

It's a holiday built over centuries.

And What Does Samhain Mean for Modern Witches?

Modern witchcraft has its own relationship with Samhain.

Many contemporary witches observe it as a time for honoring ancestors, reflecting on death and transformation, releasing what no longer serves them, practicing divination, and preparing for the darker half of the year.

Those practices can be meaningful parts of a modern spiritual practice, but they shouldn't automatically be presented as unchanged ancient Celtic customs.

Sometimes we can honor the past without pretending we know exactly what every ancient person believed.

And perhaps that's one of the most beautiful things about Samhain.

At its heart, it is about transition.

The harvest ends.

The year turns toward darkness.

One season gives way to another.

We remember what has passed, gather close to the people we love, and prepare ourselves for what comes next.

That is a tradition humans have understood for thousands of years.

And maybe that's why Samhain still feels so powerful.

Because even after all these centuries, we are still standing at the same threshold.

Still watching the leaves fall.

Still lighting fires against the darkness.

Still telling stories.

Still remembering those who came before us.

Still wondering what the next season will bring.

And that's where the magic begins. 🖤🔥🍂
