Domnonée

500 CE – 850 CE (approx.)

Breton kingdom of northern Brittany, named after Dumnonia in Britain, whose king Judicael treated with Dagobert I as an equal.

Origins

Migrants from Dumnonia in south-west Britain, the land of modern Devon and Cornwall, settled the northern coast of Armorica in the 5th and 6th centuries and gave it the name of their homeland. Its early rulers are known mainly from saints' lives, which may preserve legend.

Rule and society

The kingdom stretched along the Channel coast from the Rance to the Morlaix area. Its life centred on monastic foundations such as Saint-Malo, Dol and Saint-Pol-de-Léon, linked to saints from Wales and Cornwall. The chronicle of Fredegar records that King Judicael met Dagobert I at Clichy in 636 and made peace with the Franks.

Decline and legacy

In the 9th century Domnonée was absorbed into the Kingdom of Brittany created by Nominoe and Erispoe. The bishopric of Dol and the later counties of Penthièvre and Léon preserved parts of its territory.

Few sources survive for this state; details are uncertain.
