The Arms of the Dukes of Brittany

Roll of the Dukes of Brittany

These are the dates for their reign, beginning to end. There are some cases where the end of the reign was not the end of their life, so I give the death date if I know it. I have tried to give some indication (where I can) of how they died (or ended their reign.)
