Who were the Celts?

Because the Celts relied heavily on oral tradition, they left behind little in the way of written records. What they did leave, though, still captures the imagination: powerful artwork, ancient symbols, remarkable artefacts, and a deep connection to Irish heritage that continues to inspire people today.

But who were the Celts, where did they come from, and what were they really like?

First, let’s clear up one important thing, the pronunciation. In Ireland and Britain, Celtic is usually pronounced “Keltic” when talking about the ancient Celts, Celtic art, or Celtic heritage. Say “Seltic” here, and people may think you’re talking about the Scottish football club!

The term Celt refers more to a shared language and culture than one single ethnic group. Around three thousand years ago, Celtic-speaking peoples developed from the wider Indo-European world, with early roots in central Europe. Groups such as the Urnfield and later Hallstatt peoples helped shape what we now recognise as Celtic culture, especially during the Bronze and Iron Ages.

Over time, the Celts spread across much of northern and western Europe, from the Alps to parts of Spain, France, Britain, and Ireland. The ancient Greeks called them Keltoi, and the Gauls of France were also part of this wider Celtic world.

Roman expansion and later Germanic migrations pushed Celtic languages and traditions out of much of mainland Europe. But in places beyond Rome’s full control, especially Ireland and Scotland, Celtic culture survived and continued to shape the stories, symbols, and heritage we still celebrate today.

The Celts believed in many gods and goddesses, often connected to nature, rivers, land, and local places. Some deities were known across wider Celtic regions, while others belonged to specific communities. Their spiritual world was rich, layered, and closely tied to the landscape around them.

At the heart of Celtic society were the Druids. They were priests, teachers, healers, judges, and keepers of history. Their training could take many years, with knowledge passed down through memory and spoken tradition rather than writing.

Celtic leadership was also different from later feudal systems. Kings and chiefs were often chosen through tanistry, where leading families selected the person they believed was most fit to rule. The next leader usually came from the same family, but not always from father to son.

The Celts earned a fierce reputation as warriors, known for their bold fighting style and powerful beliefs. They saw the head as the seat of the soul, which may explain some of the more unsettling customs recorded by ancient writers. There is also evidence of Celtic warrior women and female ambassadors, showing that women could hold important roles in their society.

Despite their bravery and ability to unite tribes against common enemies, the Celts struggled against the organised power of Rome. Later, Christianity absorbed many older Celtic traditions, especially in Ireland after St. Patrick.

Ironically, much of what we know about the Celts comes from Roman writers and early Christian scribes. The Celts were not simply “illiterate”; they valued memory, speech, song, and storytelling. Their art, metalwork, and oral tradition remain some of their greatest legacies.

Today, the regions where Celtic languages still survive are known as the Celtic Nations: Ireland, Scotland, Wales, the Isle of Man, Cornwall, and Brittany. Each has kept traces of Celtic language, music, art, and identity alive in its own way.

Ireland has a strong Celtic heritage, but the Irish story is bigger than one culture alone. Over thousands of years, this island has been shaped by many peoples, from ancient settlers and Celts to Vikings, Normans, and others who left their mark. The result is the rich mix of language, history, art, and tradition we now know as Irish heritage.
