Kings and Dukes of Brittany

Brittany got its name from the British Celts who settled the region during the late Antiquity, it was previously known as Armorica. The British Celts created several different principalities and the historic sources contains many names of rulers in Brittany. But Brittany acted as a unity against external enemies and they managed to preserve considerable autonomy during the early Middle Age even if periodically acknowledged the Frankish kings supremacy. The Frankish king Louis the Pious appointed Nominoë as duke over all Brittany about 831. Nominoë later rebelled and managed to achieve complete independence from the Frankish kingdom 846. A few years later the duke of Brittany took the title king, but the Viking attacks hit Brittany very hard and they lost their independence. Brittany became a duchy again in the 10th century and fell first into strong English influence until it after 1203 came under increasingly stronger French central power, a process which was completed in the 16th century.
