Reunification of Brittany
The Reunification of Brittany or Breton Reunification is a political movement to reunite the Loire-Atlantique department with the administrative region of Brittany, to form the entire cultural and historical region of Brittany. This reunification is considered by many Breton regionalists as a prerequisite for further Breton autonomy.
