Yes but there was still a definite Breton regional identity... if the French government pushes too hard against such a thing, their efforts might backfire and lead to more Breton nationalism not less.I dunno I feel like Breton Nationalism is a pretty fringe movement considering how well Brittany was integrated into France. I don’t think a lot of Bretons would really support it.
With Catalonia the tensions started in the 19th century after its special rights to home rule were stripped.
Definitely- and the Germans would be happy to help there.Well to be fair. But there was a movement to revive the usage of Breton language and culture in the 19th and early 20th century. With France in disarray, nationalistic Bretons would want to try to create a "Free State of Brittany" (try being the key word here).
