Pays-de-la-Loire is made up of the following historical provinces:
- a part of Brittany, with its old capital Nantes: Loire-Atlantique département. This is only 20% of Brittany. The other 80% of Brittany make up the région of Bretagne.
- Anjou: Maine-et-Loire département. The whole of the fomer province of Anjou is contained inside Pays-de-la-Loire.
- Maine: Mayenne and Sarthe départements . The whole of the fomer province of Maine is contained inside Pays-de-la-Loire.
- a part of Poitou: Vendée département . Most of the old province of Poitou is inside the Poitou-Charentes région .
- a part of Perche: northeast of Sarthe département . The rest of Perche is inside the Lower Normandy and Centre régions.
- a small part of Touraine: southeast of Maine-et-Loire département. Most of the former province of Tourraine is inside the Centre région.
Consequently, the name of the région, chosen by the French central government, was not based on history, but purely on geographical references: Pays (i.e. "lands") -de-la-Loire (i.e. "of the Loire River "). It should be noted that the world famous châteaux of the Loire Valley are located in the Centre région, and not inside Pays-de-la-Loire, despite the confusing name.
There are some people in the département of Loire-Atlantique and in the région of Bretagne who are unhappy with the division of Brittany between two régions and who would like to have Loire-Atlantique enter the Bretagne région in order to reunify Brittany. So far, however, a change in the région boundaries is not on the agenda, as the tough issue of what to do with the rump Pays-de-la-Loire deprived of its capital and 21% of its territory seems hard to resolve.
