  Research Notes:

From http://cybergata.com/roots/3857.htm :
In the next few years several Viking states, similiar to the one forming in Normandy, were established in Brittany. The county of Nantes was abandoned to the Vikings in 921 by King Robert I of France. William Longsword, Duke of the Normans, aqdvanced through the Contenin and the Avaranchin. About 936, William assented to the return to Brittany of Alain Barbetote, Count of Cournaille from England - the same year that Louis IV d'Outremer returned to France from England to reestablish Carolingian rule there. An earlier attempt by Alain to his inheritance in 931 had failed.
While other Breton counts were seeking refuge at the English court, Berenger of Rennes alone remained to withstand the Viking onslaught. He was surrounded by them.
Direct contact between the rulers of Brittany and the Kings of France gradually ceased in the course of the 10th century. No Duke of Brittany acknowledged fealty of performed homage directly to the King of France until 1099. Following Alain Barbatorte's death in 952, leaving no clear heir, a power vacuum in the duchy was filled by the Counts of Rennes.
