Duke of Brittany

The Duke of Brittany was the ruler of the historic Duchy of Brittany, a region in northwest France, from the Middle Ages until 1532. The title represented both political leadership and territorial authority. The dukes often operated semi-independently, balancing power between local interests and the French crown. Over time, Brittany's autonomy was gradually integrated into France, culminating in the duchy becoming officially part of the French kingdom. The title remains historical today but no longer signifies political power.
