Conan I of Rennes

Conan I (died 27 June 992), nicknamed Le Tort (The Crooked), was the Duke of Brittany from 990 to his death. Life Count to Duke Conan was the son of Judicael Berengar, succeeding his father as Count of Rennes in 970. Conan assumed the title of Duke of Brittany in the spring of 990 following his attack on Nantes and the subsequent death of Count Alan. As Duke, his rule succeeded the Regency that governed Brittany during the life of Drogo and the fractured rule of Brittany after Drogo's death by his illegitimate brothers Hoël and Guerech, and the latter's son Alan. The fractured rule over Brittany resulted in a short vacancy in the title Duke of Brittany. Conan I had to ally himself with Odo I, Count of Blois in order to defeat Judicael Berengar before he could assume the title of Duke.
