Brian of Brittany
Brian of Brittany (c. 1042 – bef. 1086) was a Breton nobleman who fought in the service of William I of England.
A powerful magnate in south-western England
, he was the first post-Conquest earl of Cornwall.
Brian was born in about 1042, a son of Odo, Count of Penthièvre.
Brian joined in the Norman Conquest of England, along with his brothers Alan the Black
(Alain le Noir), and
Alan the Red.
Godwine and Edmund, sons of Harold Godwinson, escaped after the Battle of Hastings to Leinster, where they were guests of Diarmait.
In 1068 and 1069 Diarmait lent them the fleet of Dublin for attempted invasions of England.
At midsummer in 1069 Brian and Alan led a force that defeated a raid by a fleet of 64 ships on the mouth of the River Taw in Devon.
Later in the same year Brian and William fitz Osbern were sent to relieve sieges at Shrewsbury and Exeter by English forces rebelling against Norman lordship.
They were too late to save the former but a sally by the defenders of Exeter drove the English into the path of Brian and William who "punished their audacity with great slaughter".
After defeating Harold's sons, Brian's forces went north to counter the rebellion by Eadric the Wild, while William the Conqueror's army travelled west; the two armies joined and won the Battle of Stafford.
Brian received grants of land in Suffolk and Cornwall, although the first mention of him as Earl of Cornwall was not made until 1140, by his nephew Alan, 1st Earl of Richmond who had been given the same title by King Stephen and may have been trying to improve the legitimacy of his new rank.
Brian's name is often associated with the construction of Launceston Castle.
Brian may have left England soon after the battles of 1069, or perhaps following the rebellion of Ralph de Gaël in 1075.
In any case, his estates became part of the grants made by King William to Robert of Mortain.
Brian may have lived the rest of his life as a semi-invalid in and near Brittany, staying with his wife.
E. A. Freeman however has him holding Kastoria in Thessaly for Bohemond I of Antioch in 1083.
In 1084 he witnessed a charter of his eldest brother Geoffrey Boterel in Brittany and another in Anjou in that year; he may have died before 1086.
It is not clear whether Brian had descendants.
