Life
He was son of Duke Geoffrey I and Hawise of Normandy.[1] Alan succeeded his father as Duke of Brittany in 1008.[2] Because he was still a minor at his father's death, his mother acted as regent of Brittany [3] while her brother Richard II, Duke of Normandy assumed guardianship over Brittany.[4] In 1018 Alan married Bertha of Blois, daughter of Odo II, Count of Blois and his second wife Ermengarde of Auvergne.[1]
When Richard III, Duke of Normandy died in August of 1026, his brother Robert I succeeded him.[5] Alan apparently took advantage of the resulting turmoil to break free of Norman suzerainty.[4] In the early 1030s Robert I successfully attacked Dol and Alan's retaliatory raid on Avranches was repulsed causing continued raiding back and forth between them.[6] Facing an invasion from Normandy via land and from Duke Robert's fleet, Robert, Archbishop of Rouen mediated a truce between his two nephews at Mont Saint-Michel where Alan swore fealty to his cousin Robert.[7] When he left Normandy for the Holy Land Robert I, Duke of Normandy appointed his cousin, Alan III, to be a guardian of his young son William.[a][8] Alan III also assisted Herbert I 'Wake-Dog' in his wars with Avesgaud, Bishop of Le Mans and was with the count in his attack on Avesgaud's castle at La Ferté-Bernard destroying the castle and causing Avesgaud to flee.[9]
In 1037 at the death of Robert, Archbishop of Rouen, the protection of young William was now left to Alan III and his cousin Gilbert who tentatively held Normandy together.[10] They appointed Mauger to the now vacant see of Rouen and his brother William as count of Arques, attempting to gain their support for Duke William.[10] On 1 October 1040, while besieging a rebel castle near Vimoutiers in Normandy, Alan III suddenly died.[10] According to Orderic, he was poisoned by unnamed Normans.[b][11]
