Bretagne (or Armorica) was a kingdom having close Celtic ties with Cornwall before being assimilated into the Carolingian empire, following their defeat by the armies of King Louis the pious (818)

The early Kings were pure invention by Geoffrey of Monmouth. Dr. Peter C. Bartrum specifically notes the ones marked below with ** as being fictitious. It is therefore unclear at which point onwards credence can be given to subsequent Kings.
