The Ducs de Bretagne were the historical rulers of the region of Brittany in northwestern France. This title was held by various noble families from the 9th century until the late 16th century, when Brittany was united with the French crown. The dukes played a significant role in the region's culture, politics, and economy, often asserting their independence from the French monarchy. The most notable of the Ducs de Bretagne include Duke Francis II, the last independent duke, and his daughter, Anne of Brittany, who became queen consort of France. Their legacy is still celebrated in Brittany today, with numerous monuments and cultural references honoring their contributions to the region.
