The Celts came from central Europe although their previous origin are unclear. Around 500 BCE, perhaps to escape wars with their Germanic neighbors, they began to move westwards. Groups of people settled in what are now Spain, France, Britain and Ireland. Celts were warlike and their arrival usually led to fighting.
The Celts were artistic people. They loved stories and music and they made beautiful jewelry and metal work decorated with other abstract designs and animal shapes.
They had no written language passing their legends of gods and heros in stories around fire. Most of what we know of the Celts today comes from the writings of their enemies such as the Romans. The Celts themselves left a legacy of art and legend, and language : Welsh, Breton, Cornish, Irish and Scottish Gaelic are all Celtic languages.
