Long ago, many people lived in Europe. 


The Celts were a group of people from long ago. They lived across much of Europe. They shared similar languages and art styles. 

Scientists study how the Celts spread. Some think they moved from central Europe. Others think they moved from the west. Many different groups lived in these lands. These included the Gauls and the Britons. 
Ancient leaders and druids led the people. Druids were religious leaders. The Celts often fought with the Roman Empire. By the first century AD, Rome ruled much of their land. 
Even after Rome, Celtic ways stayed alive. People in Ireland, Scotland, and Wales kept their traditions. Today, many people still speak Celtic languages. Some of these languages are being brought back. 
The Celts were a collection of people who lived a long time ago. They were part of a large group called Indo-Europeans. These people shared similar languages and art styles across many lands. 

Historians use different clues to understand how the Celts spread. One idea is called the "Celtic from the East" theory. This theory says they started in central Europe during the late Bronze Age. This period included the Urnfield culture around 1200 BC. This was followed by the Hallstatt culture, which lasted until 500 BC. Then came the La Tène culture, named after a site in Switzerland. Another idea is the "Celtic from the West" theory. This suggests they started near the Atlantic coast and moved east. A third idea says they started in Gaul and spread in many directions. 
Writing and art tell us much about their daily lives. The earliest clear examples of the Celtic language are Lepontic inscriptions. These date back to the 6th century BC. In places like Britain and Ireland, people used Ogham inscriptions. These were written as early as the 4th century AD. 
Life for the Celts involved many different famous groups. The Gauls lived in much of Europe. The Celtiberians and Gallaeci lived in parts of Iberia. In the British Isles, there were the Britons, Picts, and Gaels. 
Even though Rome changed much, Celtic culture did not disappear. It survived in specific places like Ireland and Wales. It also stayed in Brittany and parts of Scotland. 
The Celts were a collection of Indo-European peoples who lived across Europe and Anatolia. They were not a single unified nation or one central government. Instead, they were many different tribes that shared common languages and artistic traditions. In modern studies, scholars primarily define "Celtic" by the use of Celtic languages. This group of people reached the height of their territorial expansion during the 4th century BC. At this peak, their influence stretched from the British Isles to Asia Minor. 
Historians use several theories to explain how Celtic culture spread. The "Celtic from the East" theory suggests the language began in central Europe. This theory links the Celts to the Urnfield culture around 1200 BC. It also connects them to the Hallstatt culture, which lasted until 500 BC. Finally, it points to the La Tène culture, named after a site in Switzerland. 

Archaeology and inscriptions provide the main evidence for Celtic life. The earliest undisputed Celtic language examples are Lepontic inscriptions from the 6th century BC. In the British Isles, Insular Celtic languages appear in Ogham inscriptions by the 4th century AD. Much of the early written history comes from Greco-Roman writers. These writers often described the Celts as barbarian tribes. The Celts followed a religion that was overseen by specialized leaders called druids. 
Many distinct groups made up the Celtic world. The Gauls lived in much of continental Europe. In Iberia, groups like the Celtiberians and Gallaeci occupied various lands. 
The expansion of the Roman Empire significantly changed Celtic territories. The Romans engaged in several conflicts, such as the Roman-Gallic wars and the conquest of Britain. By the 1st century AD, the Roman Empire had absorbed most Celtic lands. This included groups like the Britons, Boii, and Galatians. 
Despite these changes, a cohesive Celtic cultural entity emerged between the 5th and 8th centuries. This identity was built on shared linguistic, religious, and artistic heritage. Insular Celtic culture eventually branched into the Gaels and the Celtic Britons. The Gaels include the Irish, Scots, and Manx peoples. The Celtic Britons include the Welsh, Cornish, and Bretons. 
Today, the term "Celt" is used to describe a modern cultural identity. This identity was constructed during the Romanticist Celtic Revival in Britain and Ireland. While the ancient ethnic identity is complex, Celtic languages survive in several regions. Irish, Scottish Gaelic, Welsh, and Breton are still spoken today. Additionally, languages like Cornish and Manx are undergoing modern revivals. This connection links the ancient Indo-European roots to the modern world.
