The Bretons are a Celtic people, who settled in Brittany ( France).
About 1500 years ago, the tribe came Britto ( Breton in Latin ) from the UK - partly as refugees from Anglo-Saxon and Irish raiders, partly in the wake of targeted settlement. They have mixed with the locals and are now part of the national minorities in France. The majority belong to the Roman Catholic Church.
Since the 16th century, the Brittany is one of France. She was bilingual from the start: the western French dialect was spoken Gallo in the east of the region and the Celtic language in the West. The latter is still spoken as a Breton language today.
