Duchy of Brittany

The Duchy of Brittany was a medieval state located in the northwestern region of France, with its capital at Nantes. It was established in the 9th century as a separate entity from the Kingdom of France and had its own ruling dynasty. The Duchy maintained a certain degree of autonomy, but was often contested by the French monarchy and other neighboring states. It was united with the French crown in 1532 through a marriage alliance, but retained its own legal and administrative systems. The Duchy was known for its maritime trade and cultural distinctiveness.

Description
Brittany, the old lands of the Britons. With their mountains, and with a Celtic spirit, have now separated themselves from the French. Will the celts return the land they populated before Rome, or fall to invaders once more?

Trivia

 * Brittany can also separate if there is a rise of pan-Celticism across Scotland, Wales, Cornwall, and Ireland.
