How did Celtic culture shape Brittany’s identity?

A strong Celtic background is a defining element of Brittany’s identity, distinguishing it from the rest of France. This heritage is rooted in two distinct waves of Celtic influence:1

• Early Inhabitants: The Celts were the first historically identifiable people in the region, though they likely intermingled with the earlier Neolithic populations who constructed the area's famous megaliths, such as menhirs and dolmens.1
• Migration from Britain: In the 5th and 6th centuries, Celts fleeing Anglo-Saxon invaders in Britain settled in the region, which was then known as Armorica. This migration established the Breton language—an Insular Celtic tongue closely related to Cornish and Welsh—which remains a vital symbol of regional uniqueness.123

Beyond language, this Celtic identity has been reinforced by a history of resistance to centralization and the preservation of distinct social and religious traditions. Today, a separatist movement continues to affirm the consciousness of this unique heritage, while modern cultural revivals have sought to integrate the Breton language into contemporary life through education and media.12
