Childebert I
According to Gregory of Tours, the Bretons were divided into various "" (minor kingdoms) during the sixth century, of which Domnonée, Cornouaille, and Gwened are the best known. They initially pledged themselves to Childebert I in exchange for legitimacy. They attempted to escape Frankish rule during the time of Chilperic I, who subdued Waroch II and at least the eastern realms of the region. Guntram, Chilperic's brother, retained his lordship over Waroch and the "Brittani" formed a Frankish tributary-vassal state through the reign of Dagobert I.
