Bulletin Annuel de l'U.R.B :

The Breton Regionalist Union,(URB) was a Breton regionalist party of conservative leanings, created in 1898. It expressed a desire by certain Bretons of becoming involved in the fields of economics, of the administration and of Breton culture. A bulletin directed by the Marquis de l'Estourbillon was published from 1902 to 1943.
