The ancient Celts were a group of people who began to spread throughout Europe in the 1000s B.C. and had a reputation as fierce and courageous warriors and were viewed with respect by the Romans. .
Just a few areas, notably Ireland and northern Britain managed to remain free and to continue to pass on the Celtic traditions. Six groups of Celts have survived to modern times: the peoples of Ireland, Scotland, the Isle of Man, Wales, Cornwall, and Brittany. .
The ancient Celts were a varied people bound together by language, customs, and religion rather than by any centralized government. Each tribe was divided into three classes: the noble knights and warriors, the Druids, and the farmers and commoners. .
Their mythology of gods, heroes, and villains made up of hundreds of tales that included magic, magicians, cauldrons and the supernatural that played a significant role in the stories passed on orally by the Druids. Much of what is now known about Celtic mythology is based on manuscripts that were prepared by monks in the Middle Ages.
