Duke of BrittanyEdit
Conan II faced a daunting series of challenges to assert his rule as Duke of Brittany. His father Duke Alan III had died when Conan was still a minor, his grandfather Duke Geoffrey I's attempts at an alliance with Normandy had been reduced to border skirmishes, his uncle Odo challenged his right to rule and he faced a rebellion from Breton nobles, notably Rivallon I of Dol.
Conan's inheritance was usurped by his uncle, Odo, who initially ruled Brittany as regent during Conan's minority. However, by the time Conan reached his majority his uncle Odo refused to give up his authority. By 1057 Conan captured his uncle, whom he then had chained and imprisoned.
Brittany, an independent Celtic duchy, had a traditional rivalry with neighboring Normandy. The 1064–1065 War between Brittany and Normandy was sparked after Duke William supported Rivallon I of Dol's rebellion against Conan II. In 1065, before his invasion of Anglo-Saxon England, William of Normandy sent word to the surrounding counties, including Brittany, warning them against attacking his lands, on the grounds that his mission bore the papal banner.
Conan promptly informed the duke that he would definitely take the opportunity to invade the latter's duchy. In the history of conflicts between Brittany and Anjou, Pouancé had served as the "Breton March" or border town. During Conan's 1066 campaign against Anjou, he took Pouancé and Segré, and arrived in Château-Gontier, where he was found dead after donning poisoned riding gloves. Duke William was widely suspected. He was also asked to help William the Conqueror on his 1066 conquest of England, but refused, saying that the Normans poisoned his father in 1040.
Conan II died leaving no known issue. It is possible he died because the gloves he was wearing were poisoned, and he swallowed the poison when he wiped his mouth with the glove.
He was succeeded by his sister Hawise and brother-in-law, Hoel II, whose marriage may have been a political move to consolidate and stabilize the east and west regions of the duchy following Conan's death.
