Breton people

The Bretons (; or , ) are an ethnic group native to Brittany, north-western France. Originally, the demonym designated groups of Brittonic speakers who emigrated from southwestern Great Britain, particularly Cornwall and Devon, mostly during the Anglo-Saxon settlement of Britain. They migrated in waves from the 3rd to 9th century (most heavily from 450 to 600) to the west of Armorica. That western part of Armorica was subsequently named after them, as were the inhabitants.
