Dol rebels against Conan IIEdit

Rivallon was influenced by William the Conqueror, the Duke of Normandy.

In this period Normandy and Brittany clashed with each other in border skirmishes. Before William had become Duke, the Breton tribal lands of the Contentin Peninsula, near Dol, had been ceded to Norman rule. When Duke Alan III of Brittany died he left Brittany to his infant son Conan II with his younger brother, Odo of Penthievre, as Conan's Regent. Odo challenged Conan II by refusing to relinquish rule on Conan's achieving his majority. Conan affirmed his rule as Duke only when he imprisoned Odo in 1057.

Following this, in 1065 William, as Duke of Normandy convinced Rivallon to rebel against Conan II, Duke of Brittany with the aid of Geoffrey III of Anjou. This rebellion was the first major conflict of the Breton-Norman War.
