9th-century monarchs of Brittany

Nominoe or Nomenoe (; ; c 800,  7 March 851) was the first Duke of Brittany from 846 to his death. He is the Breton pater patriae and to Breton nationalists he is known as '''' ("father of the country").

King of Brittany

Duke of Brittany

Erispoe (; ; died 2 or 12 November 857) was Duke of Brittany from 851 to his death. After the death of his father Nominoe, he led a successful military campaign against the Franks, culminating in his victory at the Battle of Jengland. He is subsequently referred to as "King of Brittany".

Wrhwant, Gurwant, Gurwent or Gurvand () (died 876) was a claimant to the Kingdom of Brittany from 874 until his death in opposition to Pascweten, Count of Vannes.

Morman (also spelled Morvan, Morwan, or Moruuan) (died 818) was a Breton chieftain who was declared king (rex) after the death of the Bretons' Frankish overlord Charlemagne in 814. He is the first person known by name to be described as a Breton "king". He probably ruled a warband with members drawn from throughout Brittany. He had a stronghold defended by ditches, hedges and marshes.

Pascweten (died 876) was the count of Vannes and a claimant to the rule of Brittany. He was a son of Ridoredh of Vannes, a prominent and wealthy aristocrat first associated with the court of Erispoe in the 850s. He owned vast landed estates and salt works (as at Guérande) in southeastern Brittany and was a patron of Redon Abbey.

Duke of Brittany

Wihomarc or '''Wiomarc'h''' (; died 825) was a Breton chieftain "who seemed to have greater authority than the other Breton leaders" and who revolted against Frankish overlordship in 822 and held on to his power until his death. His rebellion may have been incited by the creation of a Frankish county in Poutrocoet sometime between 818 and 820.
