Gallic era

During the protohistorical period, Brittany was inhabited by five Celtic tribes:

Those people had strong economic ties to the Insular Celts, especially for the tin trade. Several tribes also belonged to an "Armorican confederation " which, according to Julius Caesar, gathered the Curiosolitae, the Redones, the Osismii, the Unelli, the Caletes, the Lemovices and the Ambibarii. The Unelli, Caletes, and Lemovices were respectively located in Cotentin (Lower-Normandy), pays de Caux (Upper-Normandy), and Limousin (Aquitaine); the location of the Ambibarii is unknown. The Caletes are sometimes also considered Belgians, and Lemovices is probably a mistake for Lexovii (Lower-Normandy).
