Where did the Celts migrate to?

The Celts migrated across various regions of Europe, primarily during the Iron Age. They spread from their original homeland in Central Europe into areas such as the British Isles, France (then known as Gaul), the Iberian Peninsula, and parts of Eastern Europe. Their movements led to the establishment of Celtic cultures in these regions, significantly influencing local languages, traditions, and social structures. By the time of the Roman expansion, Celtic tribes were well-established in many parts of Western Europe.
