Geoffrey I, Duke of Brittany (980 – November 20, 1008), also known as Geoffrey of 
Rennes and Geoffrey Berengar, was the eldest son of Duke Conan I of Brittany. He 
was Count of Rennes (ruler of the Romano-Frankish civitas of Rennes), by right of 
succession. In 992 he assumed the title of Duke of Brittany, which had long been an 
independent state, but he had little control over much of Lower Brittany.[a]

Life[edit]

Geoffrey was the son of Duke Conan I, by his marriage to Ermengarde-Gerberga of 
Anjou.[1] He was the grandson of Judicael Berengar, Count of Rennes.

When Geoffrey succeeded to Brittany he had several problems: Blois was encroaching 
on his territory, Vikings were threatening his shores, and he had to decide whether to 
accept the protection offered by Anjou.[2]

In 996, at about the age of sixteen, Geoffrey entered into a dynastic alliance with 
Richard II, Duke of Normandy,[2] with a diplomatic double marriage between the two 
houses. The church-sanctioned marriage ceremonies were held at Mont Saint-Michel, 
on the Breton-Norman border, and while Geoffrey married Hawise of Normandy, 
daughter of Richard I of Normandy and sister of Richard II,[3] Richard married Judith 
of Brittany, Geoffrey's sister.

Geoffrey and Hawise had four children:
Alan III of Brittany (997-1040)[1]
Evenus (born c. 998, died after 1037)[1]
Odo, Count of Penthièvre (died 1079)[1]
Adela, Abbess of Saint-Georges[4]

Geoffrey died on 20 November 1008 while travelling on a pilgrimage to Rome.[4]
