10th-century monarchs of Brittany

Duke of Brittany

Gourmaëlon or Wrmaelon (died 913/4), was the Count of Cornouaille and de facto ruler of Brittany from 907 – . As ruler of Brittany he was considered Prince de Bretagne in some chronicles and histories. His actual history is among the least well documented of the early medieval rulers of Brittany. His reputed time of rule coincides with a dramatic increase in Viking invasions that ultimately led up to the Viking Occupation of Brittany that began after his death.
