Over 10,000 people marched in Brittany's historic capital on the 19th of April 2014 to demand the administrative reunification of Nantes and its surrounding department, Loire Atlantique, with the rest of Brittany.
The French administrative region of Bretagne minus Nantes and Loire Atlantique department.
Currently Brittany is divided between two bodies of regional governance: 4 departments are regrouped in the administrative region of Brittany, whilst the 5th historic department of Brittany, Loire Atlantique, is attached to the totally artificial technocratic Pay de la Loire region.
The historic borders of the Duchy of Brittany.
It's worth noting that Nantes and the Loire Atlantique department were separated from Brittany by the collaborationist French 'Vichy' government during the second world war.
The current French socialist government has promised to reduce the number of administrative regions and simplify local government by abolishing the departments. Breton campaigners have therefore seized the chance to powerfully restate their desire for a reunified Brittany in which the councils of the 5 Breton departments and the regional council are fused to form a single assembly for Brittany. Another alternative being touted by some French politicians is the creation of a Grande Ouest region much like a South West or Devonwall region for Cornwall but on a much larger scale.
