The Bretons (/ˈbrɛtɒnz, -ənz, -ɒ̃z/; Breton: Bretoned or Vretoned, Breton pronunciation: [breˈtɔ̃nɛt]) 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.
The main traditional language of Brittany is Breton (Brezhoneg), spoken in Lower Brittany (i.e., the western part of the peninsula). Breton is spoken by around 206,000 people as of 2013. The other principal minority language of Brittany is Gallo, a Romance language; Gallo is spoken only in Upper Brittany, where Breton used to be spoken as well but it has seen a decline and has been less dominant in Upper Brittany since around the year 900. Currently, most Bretons' native language is standard French.
