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.[1]

Life

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:

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

Notes

  1. ^ Geoffrey, Count of Rennes, assumed the title Duke of Brittany in 992. Brittany was not then part of the emerging Kingdom of France, but earlier Dukes had paid homage to the kings of the fledgling French state. By the time of Count Geoffrey's reign, his claim to suzerainty over all of Brittany was weak, and he had virtually no control over western Brittany and Nantes. See William W. Kibler, ed., Medieval France: An Encyclopedia (New York: Garland Publishing, 1995), p. 148; The New international encyclopædia, Volume 3 (1918), p. 789
